ORBi Open Repository and Bibliography
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision).
This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.
Physicochemical properties and thermal behaviour of African wild mango (Irvingia gabonensis) seed oil. - Yamoneka, Juste; Malumba Kamba, Paul; Blecker, Christophe; Gindo, M.; Richard, Gaetan; Fauconnier, Marie-Laure; Lognay, Georges; Danthine, Sabine
African wild mango (lrvingia gabonensis) is now recognized for its numerous food and medicinal uses. This plant produces seeds rich in fat, which is traditionally used as a soup thickener. in the present
study, the proximate composition of seeds from lrvingia gabonensis is reported. The oil from the seeds was then solvent extracted; its fatty acid (FA) and triacylglycerol (TG) profiles were determined. Besides this chemical characterization, the melting and crystallization behaviour
of the extracted fat was studied by pNMR, DSC and X-ray diffraction. The result of this investigation showed that the seeds from lrvingia gabonensis (IG) represent an important source of...
Food Compounds from Meadow Grasshoppers - Paul, Aman; Frederich, Michel; Uyttenbroeck, Roel; Malik, Priyanka; Alabi, Taofic; Heuskin, Stéphanie; Blecker, Christophe; Richel, Aurore; Monty, Arnaud; Francis, Frédéric; Haubruge, Eric; Lognay, Georges; Danthine, Sabine
Eating insects as food, particularly grasshopper is practiced in many cultures throughout the world. Meadow grasshopper (Chorthippus parallelus) is commonly found in Europe and some part of Asia. It is already known that grasshoppers of Chorthippus species are consumed as food in countries such
as Thailand. With the aim of evaluating the nutritional potential of this insect species the proximate nutritional composition of grasshoppers caught from the local fields was realized. Besides this, the fatty acid profile of extracted lipids, amino acid profile and mineral composition of the insect was also revealed. Results suggest that meadow grasshopper is an excellent source...
The role of tree species diversity in drought resistance of oak and beech sapling - Rahman, Md Masudur; Carnol, Monique
Drier condition during the growing season have been predicted in the future. It has been suggested that diverse forest could maintain productivity and provide better ecosystem services under stress condition such as drought. However, those studies focused mainly on mature forest and little known about young forest. Oak and beech are the important species in European forestry, and may face a strong challenge in the future. Drought effects on young ( ̴5yr) oak and beech saplings in monoculture and mixed with other species are not known. Moreover, single studies evaluating both above- and below-ground ecosystem response to drought are scarce....
La menace climatique sur les plantes - Hambuckers, Alain
L’exposé commence par un bref rappel du contexte climatique (évolution de la température globale au cours des 150 dernières années, grandes tendances des changements climatiques prévus par les modèles globaux). Je présente ensuite quelques exemples d’observations de modification de la végétation au cours des décennies passées (enrichissement en espèces de sommets alpins, augmentation de la mortalité de la végétation ligneuse en région sahélienne, variation de la limite altitudinale de présence d’espèces endémiques sur l’île de Ténérife) et les limites de leur interprétation (prise en compte des modifications de l’occupation du sol, de la pollution atmosphérique, des interactions biotiques). On s’intéresse...
“Rhizoponics”: a novel hydroponic rhizotron for root system analyses on mature Arabidopsis thaliana plants - Mathieu, Laura; Lobet, Guillaume; Tocquin, Pierre; Périlleux, Claire
Well-developed and functional roots are critical to support plant life and reach high crop yields. Their study however, is hampered by their underground growth and characterizing complex root system architecture therefore remains a challenge. In the model plant Arabidopsis thaliana, in vitro culture remains the easiest and preferred method to study root development, which limits the analyses to young seedlings. We present here an innovative design of hydroponic rhizotron (rhizoponics) designed for the root system analysis of adult plants of Arabidopsis thaliana.
