Reinforced Composite

Abstract Tires are fabricated using single ply fiber reinforced composite materials, which consist of a set of aligned stiff fibers of steel material embedded in a softer matrix of rubber material. The main goal is to develop a mathematical model to determine the local stress and strain fields for this isotropic fiber and matrix separated by a linearly graded transition zone. This model will then yield expressions for the internal stress and strain fields surrounding a single fiber. The fields will be obtained when radial, axial, and shear loads are applied. The composite is then homogenized to determine its effective mechanical properties—elastic moduli, Poisson ratios, and shear moduli. The model allows for analysis of how composites interact in order to design composites which gain full advantage of their properties.

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.
