A Simple Mathematical Model to Calculate Dose Distribution of the Co-60 Beam
Rawaa N. Al-Shammary,
The measurement of dose distribution for any radiotherapeatic device is essential for good treatment planning. Therefore, dose distribution were measured for the field size [F.S = (10x10)cm], then...
Direct Determination of Prednisolone by Derivative UV Spectroscopy
Nada B. Shareef,
UV Derivative spectra were used for the direct quantitative determination of Prednisolone in absolute ethanol, the quantification was accomplished according to the integrated area under the peaks....
Comparison Between Washed and Unwashed Ninivite on the Removal Efficiency of Mercury from Aqueous Solutions
Muath H. Mustafa,
Ninivite is a silica rich rock, which has a very high surface area, that may exceed (800g/m2). Low grad ninivite is characterized by high absorption, adsorption ability and may act as an ion...
