Symposium on mammalian radiation genetics,July 7–9th, 1970 summary and synthesis

Papers given at the Symposium on Mammalian Radiation Genetics are summarized and discussed under three headings: (i) those helping to bridge the gap between what we know about genetic damage in the mouse and what we need to know in man; (ii) analytical studies on mice; (iii) assessment of genetic hazards from various sources.     

Form and Function in the Xenarthra–an Introduction to the Symposium Proceedings Volume

This special issue of the Journal of Mammalian Evolution represents the proceedings from a symposium held in conjunction with the 9th International Congress of Vertebrate Morphology (ICVM IX, Punta del Este, Uruguay, July 29, 2010), and entitled “Form and Function in the Xenarthra.” This symposium was the third on xenarthran biology to be presented in association with the ICVM meetings. In this brief introduction to the symposium proceedings, we plan to discuss the justification for the symposium, to provide a brief history of previous symposia and their results, and to introduce the contents of the present volume.     

New structural–optical effect in LiF–Li2B4O7 thin-film structures in the crystallization

The effect of optical radiation during the phase transition from the amorphous to the crystalline state of matter was investigated for the first time. The results were obtained on nanoscale films of (LiF)_x(Li₂B₄O₇)_1-x compositions by sputtering on cold Ni substrates. The starting materials for films were chosen due to their wide use for tissue-equivalent ionizing radiation dosimetry. It is shown that the detected thermoluminescence effect is sensitive to the thickness of the films. The paper compares the results of these studies with the study of the thermoluminescence characteristics of films irradiated by an M-30 microtron with bremsstrahlung radiation with a maximum energy of 6 MeV. The absorbed radiation dose was 1 kGy. Differences in the luminescence characteristics of irradiated and nonirradiated films were revealed. The nature of the demonstrated structural–optical effect is discussed.
