We separated platelets from whole blood and incorporated them into In-Ill and Te-99m agents. Sn-GHA, Tropolone, Oxine (sulphate) and HMPAO were used to diffuse radionuclides into the platelets. The effects of time, temperature, PH of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m C13 and Te-99m on labeling efficiency were studied.

Continual advances in information and communication technologies (ICT) are revolutionizing virtual education, and bringing new tools on the market that provide virtual solutions to a range of problems. Nevertheless, non-virtual experimentation using Computer-Aided Control System Design tools is still fundamental for future engineers. This paper describes a control course lab element, designed t...
