Plant rennets hold an important position amongst various coagulants used in cheese technology. The selection of a suitable plant coagulant is important due to the increasing global demands of cheese alongside reduced supply of calf rennet. Thus, a literature synthesis is presented to investigate recent achievements on their functional properties and enzymatic role in cheese making. Efforts have also been done to compare certain rheological and sensory properties of final products, arising from some plant and animal based rennets. In fact, some coagulants such as actinidin or dubiumin produce cheeses with sensory qualities similar to those produced by animal rennet. Others, like ginger, cucumisin or hieronymain proteases contribute to develop very different textures and flavors, due to excessive proteolytic activity and production of bitter peptides. For milk-clotting enzymes with high non-specific action, several improvement strategies have been developed to produce cheeses with sensory properties close to those of animal rennet. For example, the mixture of coagulants (cardosins/chymosin), the selection of appropriate milk or its ultrafiltration, as well as the increase of salting time of cheese during ripening could be efficient ways to improve texture and reduce bitterness. Concerning cheeses with high yield loss, the whey could be used for a traditional production of whey cheese. To conclude, the selection of appropriate plant rennet with high MCA/PA ratio and the optimization of all coagulation parameters play a central role in manufacturing cheese with superior rheological and sensory properties.

The quantification and the spatialisation of reliable SOC stocks (Mg C ha− 1) and total stock (Tg C) baselines and associated uncertainties are fundamental to detect the gains or losses in SOC, and to locate sensitive areas with low SOC levels. Here, we aim to both quantify and spatialize SOC stocks at regional scale (southern Belgium) based on data from one non-design-based or model-based sampling scheme. To this end, we developed a computation procedure based on Digital Soil Mapping techniques and stochastic simulations (Monte-Carlo) allowing the estimation of multiple (here, 10,000) independent spatialized datasets. The computation of the prediction uncertainty accounts for the errors associated to both the estimations of i) SOC stocks and ii) parameters of the spatial model. Based on these 10,000 individuals, median SOC stocks and 90% prediction intervals were computed for each pixel, as well as total SOC stocks and their 90% prediction intervals for selected sub-areas and for the entire study area. Hence, a Generalised Additive Model (GAM) explaining 69.3% of the SOC stock variance was calibrated and then validated (R2 = 0.64). The model overestimated low SOC stock (below 50 Mg C ha− 1) and underestimated high SOC stock (especially those above 100 Mg C kg− 1). A positive gradient of SOC stock occurred from the northwest to the center of Wallonia with a slight decrease on the southernmost part, correlating to the evolution of precipitation and temperature (along with elevation) and dominant land use. At the catchment scale higher SOC stocks were predicted on valley bottoms, especially for poorly drained soils under grassland. Mean predicted SOC stocks for cropland and grassland in Wallonia were of 26.58 Tg C (SD 1.52) and 43.30 Tg C (2.93), respectively. The procedure developed here allowed to predict realistic spatial patterns of SOC stocks all over agricultural lands of southern Belgium and to produce reliable statistics of total SOC stocks for each of the 20 combinations of land use/agricultural regions of Wallonia. This procedure appears useful to produce soil maps as policy tools in conducting sustainable management at regional and national scales, and to compute statistics which comply with specific requirements of reporting activities.

Given a video sequence acquired with a fixed camera, the generation of the stationary background of the scene is a challenging problem which aims at computing a reference image for a motionless background. For that purpose, we developed our method named LaBGen, which emerged as the best one during the Scene Background Modeling and Initialization (SBMI) workshop organized in 2015, and the IEEE Scene Background Modeling Contest (SBMC) organized in 2016. LaBGen combines a pixel-wise temporal median filter and a patch selection mechanism based on motion detection. To detect motion, a background subtraction algorithm decides, for each frame, which pixels belong to the background. In this paper, we describe the LaBGen method extensively, evaluate it on the SBI 2016 dataset and compare its performance with other background generation methods. We also study its computational complexity, the performance sensitivity with respect to its parameters, and the stability of the predicted background image over time with respect to the chosen background subtraction algorithm. We provide an open source C++ implementation at http://www.telecom.ulg.ac.be/labgen. [less ▲]

A coordinated supervisory control scheme for future multi-terminal High-Voltage Direct-Current (HVDC) grids is proposed. The purpose is to supervise the grid and take appropriate actions to ensure power balance and prevent or remove voltage or current limit violations. First, using DC current and voltage measurements, the power references of the various Voltage Sources Converters (VSC) are updated according to participation factors. Next, the setpoints of the converters are smoothly adjusted to track those power references, while avoiding or correcting limit violations. The latter function resorts to Model Predictive Control and a sensitivity model of the system. The efficiency of the proposed scheme has been tested through dynamic simulations of a five-terminal HVDC grid interconnecting two asynchronous AC areas and a wind farm. [less ▲]

Dans le dernier quart du XVIe siècle, Philippe II d’Espagne est à la tête de l’ensemble territorial le plus puissant d’Europe. Fils préféré de l’Église romaine et souverain reconnu d’une grande partie de l’Italie, il exerce une influence considérable sur la papauté à travers l’action de son ambassadeur espagnol résidant près le Saint-Siège. Ce dernier a pour tâche d’étendre le réseau des alliés au sein de la Curie. Il chapeaute aussi les différents services diplomatiques et ecclésiastiques des États de la monarchie présents dans la cité des papes . Si elle conserve une certaine autonomie, la légation des Pays-Bas et de la Franche-Comté près le Saint-Siège – conduite par l’agent Laurent du Blioul de 1573 à 1598 – est également soumise à la volonté de cet envoyé. Ce n’est d’ailleurs pas un hasard si l’étude de la légation à l’époque du règne de Philippe II a peu passionné les historiens . Effacée derrière la puissance de l’ambassadeur espagnol, celle-ci semble être un piètre avatar des services ecclésiastiques et diplomatiques dépêchés à Rome par les ducs de Bourgogne , Philippe le Beau ou les archiducs Albert et Isabelle . Or, si, aux temps de Laurent du Blioul, la légation, considérée en tant qu’actrice isolée dans le paysage romain, joue un rôle modeste qui se cantonne au suivi des affaires ecclésiastiques provenant des Pays-Bas et de la Franche-Comté, il faut envisager qu’elle fait partie intégrante d’une toile religieuse, diplomatique, sociale et politique plus vaste tissée à Rome par le roi Philippe II et ses agents. Dépassant les seuls intérêts des Pays-Bas, l’étude de cette institution conduit à appréhender tout un pan de la stratégie politique habsbourgeoise. L’imbrication de la légation dans le théâtre diplomatique espagnol à Rome a deux facettes : si, d’une part, elle limite les prérogatives institutionnelles de l’agent du Blioul, d’autre part, elle favorise régulièrement l’efficacité de son action.

The first part is dedicated to the study of the form and the origin of the Christian symbols, on the ground of both the oldest papyri which bear them and the literary sources about them. In the second part we analyze their disposition in the papyri and in relation to the texts they bear. Finally, in the third part, the data studied before lead to identifying the functions of the Christian symbols in the papyri. [less ▲]

En 1928, des étudiants de l’Académie des Beaux-Arts de Liège fondent la revue d’architecture et d’urbanisme L’Équerre. S’inscrivant bien que tardivement dans la continuité des avant-gardes internationales, le mensuel revendique une vision transversale de l’architecture où la réflexion plastique occupe une place centrale. Dès le départ, elle s’associe à Anthologie, revue imprégnée des théories futuristes et qui diffuse les artistes de l’avant-garde locale. D’abord par le biais de l’édition et des expositions, plasticiens et architectes travaillent ensuite ensemble dans le cadre de projets ambitieux financés par les pouvoirs publics. Cette contribution revient aux racines de cette collaboration en définissant les liens théoriques ou personnels unissant les deux revues. En se concentrant sur les infrastructures publiques, elle comment les artistes et les architectes ont répondu ensemble aux exigences concrètes de la commande en les replaçant dans le contexte social, politique et économique d’une ville belge de seconde importance à la veille de la Seconde Guerre mondiale.

This manuscript presents the work carried out within the European Project RENAISSANCE-ITN, which was dedicated to the development of innovative polyelectrolytes for energy and environmental applications. Within the project different types of innovative polyelectrolytes were synthesized such as poly(ionic liquid)s coming from renewable or natural ions, thiazolium cations, cathechol functionalities or from a new generation of cheap deep-eutectic monomers. Further, macromolecular architectures such as new poly(ionic liquid) block copolymers and new (semi)conducting polymer/polyelectrolyte complexes were also developed. As the final goal, the application of these innovative polymers in energy and environment was investigated. Important advances in energy storage technologies included the development of new carbonaceous materials, new lignin/conducting polymer biopolymer electrodes, new iongels and single-ion conducting polymer electrolytes for supercapacitors and batteries and new poly(ionic liquid) binders for batteries. On the other hand, the use of the innovative polyelectrolytes into sustainable environmental technologies led to the development of new liquid and dry water, new materials for water cleaning technologies such as floculants, oil absorbers, new recyclable organocatalysts platform and multifunctional polymer coatings with antifouling and antimicrobial properties. All in all this article demonstrates the potential of the poly(ionic liquid)s for high-value applications in Energy & Enviromental areas. [less ▲]
