the testing equipment and the methods of field tests used for calculating the modulus of deformation and elasticity of the shah _ abass dam foundation rock are described here. the communication includes conclusions of which a sharp difference between the quality of the roc kin the right and in the left bank is the most important.

Density and Ultrasonic velocity Sucrose in 1M NaCl at 298.15K, 303.15K, 308.15K and 313.15K have been measured. Various ultrasonic and solution parameters such as adiabatic compressibility, change and relative change in adiabatic compressibility, acoustic impedance, available volume and free length have been calculated using these data. The present investigation has been used to exploit the pos...
