Réponse du peuplier soumis à la combinaison simultanée de contraintes ozone et sécheresse Dans des conditions naturelles, les épisodes de sécheresse et d’augmentation des concentrations d’O3 troposphérique peuvent être concomitants. Cette combinaison de contraintes nécessite une attention particulière. En effet,...
If cryptography is the art of secrecy, then steganography may be considered as the art of hiding data secretly.To take a metaphor, steganography would be to make a file in your computer invisible where cryptography would be to lock this...
Sol-gel The sol-gel process is a wet-chemical synthesis technique for preparation of oxide gels, glasses, and ceramics at low temperature [17]. The process involves the evolution of inorganic networks from colloidal suspension (sol). In particular, the hydrolysis and condensation of...
Modern volcanology explores all aspects of volcanic eruptions, and processes occurring on micron to kilometre scales. One of the most important micro-scale processes is the formation and development of bubbles in magmas, which can have a major effect on the...
Effect of Graphene Filler on the Mechanical, Electrical, and Thermal Properties of Polymer Composite
Composite materials with organic matrices, such as carbon fiber-reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP), are increasingly being employed in multiple industrial sectors, such as aeronautic, marine, submarine, wind energy, and road vehicles. In general, the fiber-reinforced polymer...
