Biometeorological Methods provides a unified look at methodologies in biometeorology. Examples of biometeorological studies have been chosen not because the results are necessarily significant but because the method is instructive. The book begins with a brief survey of biometeorology to orient the reader approaching the subject for the first time. The remaining chapters seek to place in perspective the various experimental, empirical, analytical, and physical methods that are being used or could be used in biometeorology. Key topics discussed include space and time considerations in the sampling of the atmosphere; the design of biometeorological experiments; the use of tables, graphs, and charts in the search for biometeorological relationships; statistical and physical methods; and the synoptic approach. Also covered are studies on seasonal relationships, past climates, and climatic classification and indices. The present volume should be of value to anyone seeking assistance in the design of experiments and analysis of environmental data.

Physiology, Environment, and Man is based on a symposium conducted by the National Academy of Sciences-National Research Council, August 1966. While one might expect a textbook to present its field in organized and comprehensive fashion, a symposium necessarily follows more of an illustrative pattern, according to the personal interests or even idiosyncrasies of the participants. It is interesting to note that, in spite of these limitations, the presentations did in fact cover the range of physiological concerns with environmental effects, from the genetic to the temporal, and from the molecular to the holistic. The book opens with a discussion of the National Academy of Sciences-National Research Council’s broad-based critical study of the physiological underpinning of current concepts of biological responses to toxic chemicals and physical stresses. Subsequent chapters deal with topics such as the metabolic fate of common environmental agents; growth and trophic factors in carcinogenesis; environmental factors in aging and mortality; adaptation to heat and cold; and the definition of an optimum environment.

Advances in Water Pollution Research contains the papers that were presented at the Fourth Conference of the International Association on Water Pollution Research, held in Prague, Czech Republic, on September 2–6, 1968. This book provides information on a wide variety of subjects concerned with research on water pollution. Organized into three sections encompassing 55 chapters, this book begins with an overview of the self-purification of flowing surface waters, which is a natural, complex physico-biochemical phenomenon that has special significance in canalized rivers. This text then examines the adoption of special measures to prevent stream pollution, which is caused by the ever-increasing amounts of industrial waste waters and sewage. Other chapters consider the factors that affect the variations of water quality in rivers, including the external effects and the quantitative or qualitative variations in the volume of flowing liquid. The final chapter deals with alternative cooling water systems. This book is a valuable resource for sanitary and civil engineers.

Molecular Approaches to Ecology presents studies on the molecular aspects underlying adaptation along with discussions of the concept of molecular adaptation. A proper approach to the study of adaptation must start from the consideration of the relation organism-environment at the level of the community or of the organism, and progressively proceed from this organismic starting point to the underlying molecular aspects. Examples are presented showing that the adaptation to a given environment cannot be traced down to a single molecular mechanism. The book contains nine chapters and begins with a discussion of adaptation and natural selection. This is followed by separate chapters on the basic concepts of comparative biochemistry; the biochemical continuum and ecological integration; and the chemical properties of organisms related to physical and chemical properties of the environment. Subsequent chapters deal with isosmotic intracellular regulation; physiological radiations of biochemical systems; and metabolic relations in the production of the cocoon by the silkworm.

Principles of Regeneration focuses on the principles, methodologies, and changes involved in the process of regeneration. The book first underscores the nature of the nucleus in Acetabularia, enzyme effects, role of ribonucleic acid in morphogenesis, and functions of the stentor. The text then takes a look at the turnover in hydroids and flatworms and regeneration blastema. Discussions focus on regeneration in hydra, interstitial cells, colonial hydroids, neoblasts, and morphogenetic fields. The publication surveys segmental addition in annelids and molting, metamorphosis, and regeneration in arthropods. The termination of regeneration, importance of nerves, morphogenesis, histogenesis of the regenerate, and role of the nerves are discussed. The manuscript also examines regeneration in fishes, amphibian limb, horns and antlers, and heads and tails. The manuscript is a dependable source of data for students of developmental biology, anatomy, and evolution, as well as teachers and researchers in biology and medicine.

A Review of the Radiosensitivity of the Tissues in Bone is a report prepared by the Task Group for the International Commission on Radiological Protection Committees 1 and 2. The book reviews a biological indicator of the maximum permissible radiation dose. Data shows that an induction of malignant change should be considered as the limiting factor in maximum permissible levels for the bone. The risk of carcinogenesis in cells is connected with the proliferative potential of the cells. These cells are on bone marrow surfaces, in hematopoietic marrow, and in certain epithelial cells close to bone surfaces. The text also reviews the changes in the patterns of distribution resulting from growth and remodeling of bone. The book examines the effect of distribution of alkaline earth, of plutonium, of thorium, of americium, and of phosphorus in bone growth. The book also evaluates the comparative tumorigenic effects of external and internal irradiation of bone and the factors to be considered in determining the dose limitation from bone-seeking radionuclides. This book can prove beneficial to researchers and practitioners in the fields of radiology, internal medicine, or oncology.
