In vitro study on the effect of low level fast neutrons on cow hemoglobin

The induced changes in biophysical properties such as: viscosity and turbidity of cow hemoglobin exposed to different low level fast neutron fluences in the range from 10[5] to 10 [8]n/cm [2]are examined. The data indicated that strong correlation relations between the changes in the parameters under investigation and the molecular weight of hemoglobin specimens due to neutron irradiation. Empirical for mulae are deduced to calculate the correspondence neutron fluence from the induced effects of viscosity as well as turbidity

CO2 laser effects on the structure of gallbladder stones

The effects of three energy densities of CO2 laser on solid state characterization of gallbladder stones are investigated. The macrostructure of the stones is studied using X-ray diffraction [XRD] analysis and infrared [IR] technique. The results indicated that lasing produced remarkable changes in the crystalline structure which are proportional to the laser energy density. Moreover, data of IR technique showed variation in the optical density without changing band positions. These observed results of infrared is complemented with X-ray diffraction data
