AbstractPhase stability in alloys under irradiation is studied considering effective thermodynamic potentials. A simple kinetic model of a binary alloy with phase separation is investigated. Time evolution in the alloy results from two competing dynamics: thermal diffusion, and irradiation induced ballistic exchanges. The dynamical (steady state) phase diagram is evaluated exactly performing Kinetic Monte Carlo simulations. The solution is then compared to two theoretical frameworks: the effective quasi-interactions model as proposed by Vaks and Kamishenko, and the effective free energy model as proposed by Martin. New developments of these models are proposed to allow for quantitative comparisons. Both theoretical frameworks yield fairly good approximations to the dynamical phase diagram.

Objective: Study on 106 patients with closed head injury, assessment of serum ADH concentration, correlation with Glasgow score, sodium and plasma osmotic pressure. Patients and methods: Patients with closed head injuries were diagnosed determined by computerized tomography, admitted to the Hue Central Hospital 72 hours ago. Results: (i) Serum concentration of ADH 42.21 ± 47.80 pg/ml. (ii) There is a negative correlation between serum levels of ADH with: (1) Glasgow point r = -0.323, p <0.01; (2) Plasma sodium concentration r = - 0.211, p > 0.05; (3) Plasma osmotic pressure r = - 0.218, p> 0.05. Conclusion: There is a negative correlation between serum levels of ADH with Glasgow scale, plasma sodium concentration and osmotic pressure in plasma. Key words: ADH traumatic brain injury.
