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.

The Effects of Noise on Man covers the techniques for the evaluation of environmental noise in terms of its effects on human. The book provides the fundamental definitions of sound, its measurement, and concepts of the basic functioning, and the attributes of the auditory system. The text also presents along with their experimental basis, procedures for estimating from physical measures of noise its effects on man's auditory system and speech communications. The last part of the book is devoted to man's nonauditory system responses and includes information about the effects of noise on work performance, sleep, feelings of pain, vision, and blood circulation.

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.

Molecular Approaches to Ecology

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

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.

Ground Water Problems, Volume 11 presents the proceedings of the International Symposium held in Stockholm, Sweden in October 1966. The book covers the influence of topography on ground water formation; the ground water in Precambrian rocks in Southern Sweden; and the ground water conditions in the sedimentary rocks of Scania. The text also includes papers on the short-time variation of the ground water; some hydrogeological aspects on aquifers, especially Eskers; and the chemistry of ground waters. The tracers for ground water investigations; the protected areas for ground water sources; and the ground water production from the bedrock of Sweden are also encompassed. The book further tackles the ground water draft from earth layers; artificial replenishment of ground water; and the excursion to the Verka district.

A Review of the Radiosensitivity of the Tissues in Bone

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.

Radiation Dosimetry, Second Edition, Volume I: Fundamentals describes the significant aspects and fundamentals of radiation dosimetry. This books deals with the concepts and units of dosimetry; special problems of energy deposition in the microscopic domain; interactions of x and y rays, charged particles, and neutrons with matter; mathematical theory of radiation fields; ionization; and cavity-chamber theory. Other topics discussed include the LET distributions, Compton and photoelectric effect, pair production by photons, dosimetry principles, and interactions of neutrons with tissue elements. The calculation of neutron dose in large objects; ionization in gases, liquids, and solids; and cavity dimensions comparable with the electron ranges are also deliberated. This publication likewise covers the measurement of absorbed dose and exposure and application of cavity theory to devices other than the ionization chamber. This volume is a valuable reference for radiation workers, but is also beneficial to students and researchers interested in radiation dosimetry.

Ecology of Insect Vector Populations provides a review and appraisal of the ecology of insect vectors of disease, with particular attention to the problems of sampling adult insect vector populations. The book examines the manner in which the inter-related problems of insect ecology, behavior, and population sampling have been explored over a wide range of investigations on disease vectors. The text focuses mainly on the study of blood-sucking dipterous insects such as tse-tse flies, mosquitoes, black-flies, and midges along with the appraisal of relevant studies on house-fly and blow-fly populations. The studies of the ecology of the wingless vectors of disease or plague such as the fleas are carried out extensively. The dissertation will be of interest to medical entomologists, animal ecologists, and epidemiologists.

Weather Studies presents thorough discussions on various aspects of weather and weather studies. This text first presents the methods of measuring the weather, including measuring the temperature, humidity, rainfall, snowfall, visibility, wind force and direction, and pressure. Then, this book explains how to put these measurements in graphs to better present the data. This topic is followed by discussions on “weather in pairs,” or the relationships of weather measurements, such as of temperature and pressure, wind, and humidity, as well as of visibility and wind direction and humidity. This book ends by discussing local weather and forecasting the weather. This selection will be very invaluable to those studying the weather, including weather researchers, meteorologists, and students of meteorology.
