IN VIVO STUDIES OF RADIATION POTENTIATON BY IODOACETAMIDE AND OBSERVATIONS ON TUMOR TRANSPLANTATION IMMUNITY

Description: Iodoacetamide has been shown by others to be a radiation sensitizer for bacteria and for certain mammalian cells tested in vitro. This work describes an examination of the effectiveness of iodoacetamide used in vivo. Survival of ascites tumor cells maintained in the peritoneal cavity of mice was used as an indicator of sensitization. Survival was assessed using TD{sub 50} and total tumor cell population determination methods. A comparison of results obtained by these methods is made. The effect… more

Climb of Dislocations in Magnesium Oxide Single Crystals

Description: The wave like pattern, observed in dislocation dipoles of uniform spacing during annealing, which starts from the ends of the dipole and gets damped toward the centre, has been attributed to controlled vacancy migration. A theory has been set-up to give activation energy for the process, 60,700 + 2,000 cal/mole. This value has been compared with an independent study of pipe diffusion, in which a prismatic loop inside the foil is connect to both surfaces of the foil by screw dislocation.

Velocity of Sound in Solid Krypton.

Description: Technical report documenting the methods and results of experiments with krypton, which involved using "ultrasonic pulse-echo measurements [...] on specimens of solid krypton prepared in a rigid-tail helium cryostat" (p. i). The report also discusses shortfalls in existing models to explain the high- and low-temperature thermoelastic properties of the element.
