In a context of high productivity, eggs’ quality assessment is necessary for enhanced safety and quality assurance towards the consumers and feedback for producers. The quality assessment of eggs and egg products is performed using destructive and time-consuming methods, therefore the use of rapid tools becomes mandatory, especially in the case of a high production rate. Near Infrared (NIR) spectroscopy is considered a very reliable and rapid technique with large use in food industry. At the farm level, NIR spectroscopy technique would be an interesting tool to determine the chemical and physical properties of eggs, eggshell and internal quality and, moreover, this information may help the layer farm manager when a problem occurs in the flock. Its application in the egg industry is aimed at the quality changes in eggs during storage and quality assessment of the egg products, through the compositional analysis. It is possible and in some cases successful the prediction and/or determination of different parameters such as: protein, total lipid and total solids content (for liquid egg products), polyunsaturated fatty acids (for freeze-dried egg yolk), moisture, fat and protein content (for spray-dried whole eggs). In addition, for the white colored shell eggs, the detection of blood and meat spots is also successful. Further studies with NIR and near infrared hyper spectral imaging system (NIR-HSI) are needed in this direction, as the results obtained until now are very promising for the development of a rapid tool for quality assessment of eggs and egg products.

The Mediterranean Sea is an enclosed basin, highly submitted to anthropogenic pressures. Chemical pollution originating from coastal urban centres and industries, or carried by air and rivers, will primarily affect its coastal ecosystems. The pollution by trace elements into the marine environment is rapidly evolving further to the recent modifications of their production and industrial uses by men. As a result, some trace elements that were previously poorly studied can be considered now as environmental pollutants, whose concentrations can sometimes be way above their natural baseline levels. The purple sea urchin Paracentrotus lividus is a well know bioindicator used for metal pollution monitoring (Fe, Cd, Cr, Pb, Zn and Cu) along the Mediterranean and Atlantic coasts. This sedentary organism successfully concentrates the pollutants diluted in its environment, and the measured concentrations reflect properly the health status of the ecosystem. This study is a first approach on the use of P. lividus as bioindicator for some less investigated trace elements (Al, V, Mn, Co, Ni, Se, Mo and Ag), chosen for their potential toxic effects. We have compared the element concentrations of the digestive tract tissues and gonads of female and male sea urchins. The organisms were frozen prior to dissection, or they were dissected alive, the two experimental procedures being compared afterwards. The existence of an eventual relationship between their gonadic index or their test diameter and the measured pollutant concentrations was also investigated. [less ▲]

Car manufacturers are faced with increasingly severe European regulations concerning End of Live Vehicles (ELV) recycling. Issues for the coarse fractions of Automotive Shredder Residue (ASR) are now quite largely studied. However, the European objectives could only be achieved by considering the processing and valorization of the fine ASR fraction (< 2mm) which usually represents 5 to 10 wt.% of shredded ELV. A laboratory study was carried out on the fine ASR fraction. By combining granulometric, gravimetric and magnetic separations, four valorizable fractions were identified. This paper presents the valorization of the finest fraction (< 250 μm) as filler in bituminous concrete. Physical and chemical properties were first determined. Bituminous concrete samples were then prepared with different substitution levels of calcareous filler by fine ASR. Marshall tests (mechanical properties) and leaching tests were performed without compromising results. [less ▲]

Doubly tunable sum frequency generation (SFG) spectra demonstrate that the water molecules at gold/electrolyte interface change their orientation with applied potential. At negative potentials, water molecules in the double layer align with their oxygen atom pointing to the solution. As potential became positive to be close to the potential of zero charge (PZC), the SFG signal decreased, suggesting the OH groups of the water molecule are either in random orientation or parallel to the electrode. As potential became more positive than the PZC, the SFG signal increased again with the oxygen-up orientation as same as in the negative potential region, indicating that water molecules interact with the adsorbed sulfate anions. The peak position of the SFG spectra indicates a relatively disordered state of water molecules at the gold electrode surface, in contrast to the previously observed ice-like structure of water at electrolyte/oxide interfaces.

Le très controversé robinier (une bonne trouvaille pour les uns, une menace écologique pour les autres) fait l’objet de plusieurs études en Région wallonne, entre autres au sein de « l’accord cadre de recherche forestière » depuis 2000. L’objectif est de mieux connaître cette essence et son potentiel en sylviculture, et d’évaluer, à partir d’observations et de mesures réalisées au sein de nos peuplements régionaux, si les connaissances étrangères (hongroises surtout) peuvent être transposées à la Wallonie, comme cela a notamment été le cas dans le Fichier écologique des essences.
