Objectives Modelling microscopic properties of rock allows simulation of non-linear and complex macroscopic behaviour. Rather than specifying a "true" representation of rock at a microscopic scale, models use empirical properties at a mesoscopic scale such that the correct macroscopic behaviour is simulated. The objectives of the session \Modelling the micro-physics underlying earthquake nuclea...

Phenomenological and theoretical aspects of fragmentation for elementary particles (resp. nuclei) are discussed. It is shown that some concepts of classical fragmentation remain relevant in a microscopic framework, exhibiting non-trivial properties of quantum relativistic field theory (resp. lattice percolation).

Abstract Red mud, a by-product of alumina production, has great impact on the environment due to its high alkalinity. In this paper, two-part geopolymer mortar was synthesized by combining red mud and blast furnace slag (BFS) obtain optimized compressive strength flexural for construction materials. Geopolymer concrete prepared with cementitious material in replaced mortar. Mechanical propertie...

A major challenge in biology is to understand how molecular processes determine phenotypic features. We address this fundamental problem in a class of model systems by developing a general mathematical framework that allows the calculation of mesoscopic properties from the knowledge of microscopic Markovian transition probabilities. We show how exact analytic formulae for the first and second m...

Using molecular-dynamics computer simulations we investigate how in silica the glass transition and the properties of the resulting glass depend on the cooling rate with which the sample is cooled. By coupling the system to a heat bath with temperature Tb(t), we cool the system linearly in time, Tb(t)5Ti2gt , where g is the cooling rate. In qualitative accordance with experiments, the temperatu...

Abstract Fission properties of the actinide nuclei are deduced from theoretical analysis. We investigate potential energy surfaces and fission barriers predict fragment mass yields isotopes. The results compared with experimental data where available. calculations were performed in macroscopic-microscopic approximation Lublin-Strasbourg Drop (LSD) for macroscopic part, microscopic corrections e...
