Phone 653-4121 [S/NCE 1925] -Micro-encapsulation tech niques can lead to 38 per cent efficienty —Water-degradable polymers and difficulty soluble substances can have efficiencies of 50 per cent for spheres and 70 percent for slabs —A simple combination of water-degradable slabs and conventional material can lead to 100 per cent efficiency, which is of course the ideal In more than a year of laboratory work, Dr Collins and co-researcher Silvia Doglia, postdoctoral student from Milan, Italy, solve the diffusion equation enabling them to make the efficiency comparisons Dr Collins says their diffusion solution disproved the currently accepted diffusion equation of Takeru Higuchi and further proved that a constant efficiency can be expected from that technique other solar radiation can cause permanent eye injury and could lead to blindness “Especially at this time of year,” Dr Perka said, “when the sun hangs low on the horizon, should eyes be given every protection possible ” He said the outdoorsman, especially when there is snow on the ground to reflect light rays, should wear optically-ground sunglasses These sunglasses, he said, should be dense enough to allow only 20 to 30 percent of the sun’s visible light through and they should absorb some of the in frared and ultraviolet radiation as well 21
