ORBi Open Repository and Bibliography (260.650 recursos)

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.

  4. ANALYSE DE LA DEMANDE EN CHARBON DE BOIS PAR LES MÉNAGES URBAINS DE BUJUMBURA AU BURUNDI

    Sabuhungu, Emery Gaspard
    The objective of this study is to evaluate the demand for charcoal by urban households in Bujumbura in order to make recommendations ensuring the security of household energy and environmental protection. To achieve this objective, the analysis of the related documentation and collection of secondary data were carried out in order to formulate specific objectives, hypotheses and the methodology used in the course of this study. The specific objectives are: to analyze the structure, operation and market performance of the charcoal market in the city of Bujumbura and to compare this market to the cities of Lubumbashi and Kigali; to...

  8. Identifying wheat varieties with low acrylamide potential

    Lecart, Brieuc
    Maillard reactions are responsible for the formation of many compounds in food that have been baked at temperatures above 120°C1. Some of these compounds are sought for their contribution to the organoleptic qualities of food but others, such as acrylamide, have been identified since 1986 as reprotoxic, genotoxic and carcinogenic in animals2. Synthesized from a chain reaction between free sugars and free asparagine, acrylamide has been found in many food such as products prepared from wheat flour1,3,4. The correlation between the amount of free sugars and free asparagine in raw food with the acrylamide content in the baked food has been well...

  9. Assaying asparagine content in a complex matrix using a spectrophotometric method

    Lecart, Brieuc
    In this study we show, on 15 wheat varieties, the ability to assay the asparagine content in a complex matrix such as wheat flour by a simple spectrophotometric assay. This method is easier, faster and cheaper than conventional chromatography analysis and allow to discriminate quickly which materials has high or low level of this amino acid. Asparagine is an amino acid present in free form in the food biomass and has the property of reacting with the free sugars during the Maillard reactions that occur during baking at temperatures above 120°C. The Acrylamide resulting from this reaction chain has been...

  11. Quantification of nitrogen stress on winter wheat by multispectral vision based on reflectance measurements and textural descriptors

    Marlier, Guillaume; Gritten, Fanny; Fraipont, Guillaume; Leemans, Vincent; Dumont, Benjamin; Destain, Marie-France; Mercatoris, Benoît
    Hand-held sensors (SPAD meter, N-Tester, …) are used for detecting the leaves nitrogen concentration (Nc) on the basis of an optical detection of the chlorophyll concentration. These devices are active sensors: an internal radiation source emits light and transmission through a leaf is measured in the red (650 nm) and in the near-infrared (920 nm) spectral regions. These devices present several drawbacks. The nitrogen concentration is gained by an indirect way through the chlorophyll concentration and the leaves have to be fixed in a defined position for the measurements. These drawbacks could be overcome by an imaging device that measures...
