In this study the processes affecting groundwater chemistry in the Eocene Brussels sands aquifer in Central Belgium are identified based on evaluation of ionic ratios of major solutes. Based on these results, in combination with mineralogical and hydrogeological information of the aquifer, a geochemical mass-balance model is created to quantify the contribution of each of the processes to the observed composition of groundwater. After a rigorous validation process, a dataset of 99 groundwater samples is obtained from observation and pumping wells in the Eocene Brussels sands aquifer, which is one of the main aquifers for drinking water production in Belgium. The aquifer consists of heterogeneous alteration of calcified and silicified coarse sands, with local presence of clay drapes and glauconite-rich zones (Laga et al. 2001). The entire aquifer is overlain by Quaternary eolian deposits, mainly consisting of loam with the exception of the north east, where the Quaternary deposits are sandy loam. The groundwater in this aquifer is of Ca-Mg-HCO3-type with locally elevated nitrate concentrations. Based on the evaluation of ionic ratios and the mineralogy of the aquifer, a conceptual geochemical model is developed for mass-balance modeling, including (1) concentration of precipitation by a factor 1 to 5 due to evaporation, (2) dissolution of a pure calcite phase and a calcite phase containing 25 % magnesium by both carbonic acid and sulfuric acid, (3) anthropogenic inputs for all major cations and anions except bicarbonate, (4) dissolution of glauconite, (5) cation exchange of sodium and potassium for calcium and magnesium. The two calcite phases can be thought of as end-members of a solid solution of magnesium in calcite. The mass-balance modeling consists of a mole-balance equation for each considered element according to: [Obs] = p[Prec] + p1[Phase 1] + ... + pi[Phase i] + a [Anthropogenic] +/- c[Cation Exchange] This set of linear equations is additionally constrained by (1) defining a range for concentration factors p based on measured and calculated evaporation rates, (2) charge balance for the anthropogenic sources and (3) pi being positive or negative according to whether the phase dissolves or precipitates. The set of linear equations with the given constraints is solved using a least squares optimization. Based on the possible processes and reactions several geochemical models are tested for each sample and a model is considered adequate if the root mean squared error (RMSE) between observed and calculated concentrations is less than 10-10 mol/L and the charge balance of the calculated composition is less than 5 %. If several models are able to explain the observed concentrations, the RMSE provides an objective measure to compare the quality of the models. The best model for each sample is selected and the spatial distribution of these models is compared to the spatial variations in lithology and land-use to asses the feasibility of the proposed models.

Le Gouvernement de la Région wallonne (Belgique) a confié à l'unité de recherche la tâche d'inventorier les différentes directives relatives au calcul de la distance à respecter entre les bâtiments d'élevage (dont les élevages de volailles) et les habitations pour assurer un niveau d'acceptabilité de l'odeur générée. Huit formules de calcul, appliquées dans différents pays, ont été examinées et comparées et une étude de sensibilité des différents paramètres a été menée. Cette première comparaison a donné lieu à une appréciation des différentes méthodologies, selon des critères de pertinence par rapport à la réalité de terrain, de faisabilité technique, d'applicabilité à la Région wallonne et de cohérence avec les théories de la génération et de la dispersion des odeurs. Sur base de ces différents éléments, une formule originale a été proposée : elle permet de calculer une distance d'acceptabilité de la nuisance olfactive sur base de facteurs multiplicatifs incluant les éléments suivants : nombre et type d'animaux, facteurs techniques de l'étable (type, stockage et manipulation de la litière, ventilation, nourriture), environnement orographique et météorologique et type de voisinage. Les différents paramètres de cette formule ont été ajustés grâce à des visites de terrain, puis la formule a été validée sur 22 poulaillers et élevages de canards. La compatibilité a été testée avec les unités d'odeur, les débits d'odeur et les percentiles spatio-temporels utilisés pour apprécier les zones de nuisances olfactives. [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 ▲]

This study investigated the influence of four modalities of wheat (Triticum aestivum L.) presentations on the performances and digestive tract characteristics of broilers (Ross). The variety of wheat was Meunier. The first dietary treatment (Milled) corresponded to milled wheat (hammer mill, sieve of 3 mm). The second treatment (Rolled) was related to rolled wheat. The third dietary treatment (Whole-Advanced) corresponded to 10 % whole wheat for first week of study (d 10 to d 17), 20 % whole wheat for second week of study (d 17 to d 24) and 30 % after d 24. The fourth treatment (Whole-Belated) was similar to the third, except a delay equals to 1 week (10 % for d 17 to d 24, 20 % for d 24 to d 31 and 30 % after d 31). Except for the first week of study, intake of Milled was inferior (p < 0.05) to other treatments. From the second week (between d 17 and d 24), growth related to Rolled was higher (p < 0.05) than two whole wheat treatments. From the third week (between d 24 and d 31), growth related to Rolled was also higher (p < 0.05) than Milled. Cumulated feed conversion ratio (FCRc) of Milled and Rolled was better (p < 0.05) than FCRc of whole wheat treatments (30 % of whole grain in fine). With this two whole wheat incorporation schemes, 20 or 30 % of whole grain was superior (p < 0.05) to Milled for FCR. The gizzards of broilers related to whole wheat were proportionally heavier (p < 0.05) than gizzards associated to Milled or Rolled. Rolled was not different (p > 0.05) from Milled for weights of gizzards. [less ▲]

Although linear systems are now very well-understood in the context of structural dynamics, this is not at all the case for nonlinear systems. In particular, despite huge advances in the mathematical theory of nonlinear dynamical systems, progress in the difficult field of nonlinear system identification (learning of models from measured input/output data) has largely remained fairly slow and incremental. This is not to say that there have been no major successes in the field in its comparatively short history, and the objective of this paper is to present some of the highlights, as perceived by the authors, and to pave the way for a second paper discussing new developments and possibilities for the future.

Thiamine, also known as vitamin B1, and its different phosphorylated derivates are found in all known organisms. The main form of the vitamin is the coenzyme thiamine diphosphate (ThDP). Thiamine triphosphate (ThTP) is also found in low amounts in all organisms studied from bacteria to mammals. In E. coli ThTP accumulation is linked to amino acid starvation and the presence of a suitable carbon source. Recently a new thiamine derivative, adenosine thiamine triphosphate (AThTP) or thiaminylated ATP was discovered in our laboratory. AThTP is accumulated in E. coli during carbon starvation. When the cells are grown under optimal conditions (rich medium containing amino acids) neither ThTP nor AThTP is present in significant amounts. The synthesis of both compounds is inhibited by amino acids. In E. coli, AThTP accumulates in response to two different conditions of metabolic stress: lack of energy substrates (or inhibition of their metabolization) and uncoupled pyruvate oxidation.

L’image photographique devient une ressource dans les mains des acteurs sociaux et fait fonction de diagnostic des tensions du contemporain. La photographie permet de « reconnaître à travers » (c’est-à-dire « diagnostiquer ») et de formuler des jugements. Le potentiel sémantique du diagnostic engendré par cette série et la force illocutoire des jugements qui y sont inscrits fonctionnent comme une sorte d’« argumentation par images ».

This paper addresses a new, unified thermomechanical constitutive model for unsaturated soils through a coupled study. In the context of elastoplasticity and the critical state theory, the model uses the concepts of multi-mechanism and bounding surface theory. This advanced constitutive approach involves thermo-plasticity of saturated and unsaturated soils. Bishop’s effective stress framework is adopted to represent the stress state in the soil. This stress is linked to the water retention curve, which is represented by an elasto-plastic model. Attention is focused particularly on the coupling relations inferred from this unified thermo-hydro-mechanical (THM) study. Finally, the theoretical aspects of the paper are supported by comparisons between numerical simulations and experimental results. [less ▲]

The availability of IKONOS stereo pairs has made it possible to generate Digital Surface Models of IKONOS data. Though it is possible to obtain a DSM from two images with a different viewing angle on the same area, it is preferred to work with products ordered as stereo. Such stereo pairs have images that are made in the same orbital pass, resulting in a much better geometry of the stereo model. In this paper the accuracy of an IKONOS derived DSM of urban areas is assessed, based on DSMs from aerial photography and laser scanning. The quality and accuracy of a DSM derived from IKONOS stereo pairs has been assessed for test zones in two cities, Ghent and Liege. The test zones are characterized by a typical urban morphology (city center, residential, industry). The accuracy has been assessed for each of the different types of urban morphology in the study areas. An error surface is obtained by calculating the difference between the generated IKONOS surface models and reference surface models. This surface is used as a measure for the accuracy of the IKONOS surface model. Reference surface models from different origins are used (aerial photography, lidar, large scale 3D database). For the test zones in Liege, the relation between the DSM accuracy and different land cover types is studied in detail. Also the relation between DSM error and the topography will be investigated.

As scaling of the critical transistor dimensions below 65 nm has been slowed down, the implementation of novel materials, especially high mobility channel materials is most attractive to boost the transistor performance. Applying strain to silicon has become a successful route. The electron mobility can be enhanced by biaxial strain introduced into Si by epitaxial growth of Si on a strain relaxed SiGe layer or by so called process induced methods applied directly on transistor level. The combination of strained Si and SOI is particularly promising due to the combination of the enhanced mobilities and the inherent advantages of SOI. First long channel n-MOSFETs with gate lengths of 5 to 50 mum and a 6.6 nm thick SiO2 gate dielectric were fabricated. For comparison, devices on unstrained SOI were made. The transfer characteristics of a fully depleted sSOI-MOSFET with a gate length of 5 mum and a gate width of 20 mum indicating an inverse sub-threshold slope of 75mV/dec. [less ▲]

Aphids are important pests of crop plants in Europe. Increasing resistance of aphids to insecticides and their side effects on the environment and non target organism's including human's stimulated research on alterative methods of aphid control, including the use of entomotoxic proteins. Lectins are carbohydrate binding proteins that are widely distributed in nature; they have been isolated from microorganisms, fungi, plants and animals. Several of these proteins were tested for their potential biocide effect on plenty of pests. A fungal lectin, namely Xerocomus Chrysenteron lectin (XCL) was previously purified and was shown to be toxic for several pests including aphids. XCL was clearly the most toxic lectin against M. persicae. In this work, bioassays using artificial diets incorporating a broad range of XCL concentrations (from 10 microg x ml(-1) to 5000 microg x ml(-1)) were developed to assess the negative effects of XCL on the biological parameters (development duration, weight and fecundity) of M. persicae a polyphagous aphid found on more than 400 host plant species and transmitting more than 100 viral diseases. A significant mortality of aphids was observed, corresponding to the LC50 and LC90 of 0, 46 and 6, 02 mg/ml respectively after 24hrs. Significant differences of M. persicae weight, development duration and fecundity (P < 0.05) was observed between the tested XCL concentrations.

Cette étude aborde l'épineuse question du style cinématographique. En étudiant deux séquences spécifiques, l'une tirée d'un film de Fritz Lang, l'autre d'un film de Max Nosseck, il s'agit de dépasser les paradoxes inhérents à la notion de "style" (marque auctoriale vs norme collective) en leur opposant le concept de "reconfiguration", mixte plus ou moins subtil de reprise et de novation, de citation et d’écart.

Senecio inaequidens DC. (Asteraceae) est une plante invasive originaire d’Afrique du Sud et du Lesotho. Introduite involontairement par l’industrie lainière il y a environ un siècle, dans des zones indépendantes et connues, elle s’est répandue à travers l’Europe de l’ouest. Des collectes de graines et des mesures in situ ont été menés le long de deux gradients altitudinaux et climatiques, passant par les zones d’introduction de Belgique et du sud de la France (respectivement 8 et 10 populations). Dix individus parents, par population, ont été échantillonnés. Dix graines par individu parent ont été semées en pots, et une plantule a été gardée, dans un jardin expérimental homogènes, à Gembloux (Belgique). Ceci afin d’étudier les éventuelles différenciations génétiques le long des gradients climatiques. Les données collectées concernent la germination, la phénologie de la floraison, la croissance (hauteur, biomasse) et le succès reproducteur. Une relation entre la plupart des traits d’histoire de vie étudiés et l’altitude a été montrée pour le gradient français, reflétant une différenciation adaptative de l’espèce au cours de l’invasion. Les plants de basse altitude (région méditerranéenne) tendent à germer plus tôt, à être plus grand, à fleurir à un âge plus avancé et à allouer plus de ressources à la croissance qu’à la reproduction. In situ, un patron altitudinal similaire est observé pour la hauteur et la biomasse. Les résultats du gradient belge sont aussi comparables pour les traits relatifs à la croissance, mais moins marqués. Ceci est à mettre en relation avec une moins grande différence d’altitude, des climats moins contrastés et un flux de gènes potentiellement plus important le long du gradient de colonisation belge.

The paper summarizes the investigations on shear resistance of I-girders longitudinally stiffened by closed trapezoidal stiffeners, performed in the frame of a European RFCS project (RFS-CR-03018) designated as “ComBri” (Competitive Steel and Composite Bridges by improved Steel Plated Structures), with configurations typical of what may be expected in the design of modern steel bridges. It first reports on four full-scale tests performed at RWTH Aachen, on stiffened panels with strong closed stiffeners where the deformations have been measured with photogrammetric devices. As expected, failure in the subpanels has been governing. A devoted FEA shell model is then described and validated towards these results and other experimental sources. The numerical simulations demonstrate a very good agreement with the test-results. Parametric studies performed with a sophisticated numerical tool help pointing out several aspects where the recommendations of EN 1993-1-5 [1] on stiffened panels in bending and shear may be improved.

In this paper, different modeling philosophies are explored in order to explain and forecast daily traffic counts. The main objectives of this study are the analysis of the impact of holidays on daily traffic, and the forecasting of future traffic counts. Data coming from single inductive loop detectors, collected in 2003, 2004 and 2005, were used for the analysis. The different models that were investigated showed that the variation in daily traffic counts could be explained by weekly cycles. The Box-Tiao modeling approach was applied to quantify the effect of holidays on daily traffic. The results showed that traffic counts were significantly lower for holiday periods. When the different modeling techniques were compared with respect to forecasting with a large forecast horizon, Box-Tiao modeling clearly outperformed the other modeling strategies. Simultaneous modeling of both the underlying reasons of travel, and revealed traffic patterns, certainly is a challenge for further research. [less ▲]
