This atlas contains 147 bright-field photomicrographs that illustrate the anatomy of bacteria, algae, fungi, lichens, mosses, liverworts, ferns, conifers, and flowering plants. With each micrograph, there is an interpretive line drawing which is useful since many of the photographs are of fair quality only. The book is representative of thinking in the field of plant anatomy 50 years ago. There...

Ionizing radiation at low LET is more effective in the presence of oxygen than in its absence in producing most biological effects. Most experimental radiobiological irradiations are conducted in the presence of oxygen at sufficient concentration to produce a “full oxygen effect”. To understand the full oxygen effect it is helpful to review the traditional definition of OER, which is the ratio ...

several thousand sets of quotation marks, parentheses, and italics. Hardly a page in the book does not have at least a dozen words in quotations unnecessarily. Despite these objections there is much useful information in the book, which would be well for physicians to know. The book is at its best when it discusses sex education of the child and parental attitudes toward children. It is at its ...

Radiation biology is a highly interdisciplinary field at the interface of biology, physics, and medicine. It is characterized by rapid advances in biological and technical knowledge. The potential for using these advances to optimize medical care, radiation protection, and related fields can be exploited only with complementary activities to support the education of young academics. A small num...
