Specialization: Chemical Engineering Degree: Master of Science Abstract: Metallurgical coke is an important raw material for iron making in a blast furnace. Two significant criteria for selecting high quality coke are Coke Reactivity Index (CRI) and Coke Strength after Reaction with carbon dioxide (...

International audience For students, the pressing demands for memorization, top-level performance, and peer competition create an environment favorable for pharmaceutical cognitive doping behavior. We aimed to describe recent practices and the benefit/risk ratio of such behavior and to discuss the i...

The aim of this research was to determine the “chaînes opératoires” of colouring materials in the north-western Mediterranean region during the Early and Middle Neolithic and to integrate them in chrono-cultural framework. Two major archaeological sites were selected: Castellar – Pendimoun rock-shel...

In order to control the risks to which workers are exposed at their workstations, it is necessary to know the hazardous properties of the substances they use manually or in industrial processes. Most of these data are summarised in the safety data sheets of the handled substances and are usually obt...

Summary The goats live in arid regions as a result of their adaptation to extreme conditions. Dietary selection is one of the behavioural strategies that have allowed them to avoid nutritional deficiencies or intoxications even under conditions of low food availability. In addition, as an inestive b...

Specialization: Chemical Engineering Degree: Master of Science Abstract: The utilization of waste materials to generate value-added products is an appealing prospect that can generate economic and environmental benefits. When the end product of this process is itself environmentally friendly, the be...

[ES] Bio-waste is the biodegradable fraction of municipal waste (UK). Currently, in many cities, they are still collected together with the remaining fraction, so a large amount of bio-waste goes to landfills. Separate collection of this fraction would facilitate recycling. This would bring a number...

Micropollutants (MPs) represent an important environmental and health issue. Identifying their sources and then reducing their discharges is the strategy used in France to fight against water pollution. This is also the approach implemented in the Regard project (Reduction and management of micropol...

International audience Octahedral molybdenum clusters were found to be efficient visible light homogeneous photocatalysts for the reduction of carbon dioxide (CO 2) to methanol. Photoreduction was carried out by using 20 watt white cold LED flood light in dimethyl formamide/water or acetoni-trile/wa...

The regulation of cell death is crucial for the life living beings. The programmed cell death (PCD) can be triggered by extra- or intracellular signals under physiological (PCD is essential for normal development and tissue homeostasis) or pathological conditions for eliminating impaired cells (nota...
