Effects of Ionizing Radiations on Immune Processes
establishment of new neural connections rather than the modification of existing sets. Blinded octopuses can acquire certain kinds of discriminations based upon tactile or chemical stimulation. The results of a textual discrimination experiment with grooved cylinders suggest that the "discrimination of the topographical features of objects touched may be based simply upon the proportion of sens...
متن کاملRadiation Effects and Damage 1. Ionizing Radiations
The detrimental consequences of radiation are referred to as radiation damage. To understand the effects of radiation, one must first be familiar with the radiations and their interaction mechanisms. Further, the fundamental characteristics of the material(s) being irradiated must also be understood. A brief summary of the characteristics of radiation is first presented below. This is followed ...

متن کاملBiological Effects of Low Doses of Ionizing Radiations: Particle Tracks in Radiobiology
A radiation field is made up of a tangle of particle tracks, from the primary particle and secondary and higher generation electron interactions, well isolated at low doses and with multiple intersections in cell nuclei at high doses. Low dose effects in multicellular systems are therefore the sum of individual track structures. Until we can state with confidence the structure of a particle tra...
متن کاملThe Initial Effects of Ionizing Radiations on Cells
divides into the Lorisiform lemurs and the Lemuriform lemurs. There is some justification for this, yet the unique features of the Malagasy (Lemuriform) lemurs does argue that the nocturnal lorises of Asia and Africa are better kept in a separate category. But here we go arguing terminology, a deplorably bad habit which Sir Wilfred has noted is a characteristic trait of students of the Primates...
