Fruit Growing studies fruits, including its characterization and kinds; essential agricultural, horticultural, and silvicultural practices; and consumption. This book first qualifies what fruit is and then discusses some fruits such as berries and bush fruits. Various practices in growing, maintaining, and harvesting fruits are then examined, including cutting, layering, pruning, stooling, grafting, and pruning. How to plan and maintain a fruit garden is also explained. The latter part concerns itself with fruit storage, preparation, and record keeping. This text is a very helpful guide for those interested in putting up their own fruit garden, as well as to those in the field of agriculture, horticulture, human nutrition, and food technology.

Existing Mechanisms of Arms Control is a five-chapter text that considers the mechanisms for the international control of warlike materials, principally fissile material. This book emphasizes the very few cases where states have already come together and, by formal treaties, bilateral or multilateral, have set up systems and organizations for the international control, under international inspection, of weapons and warlike materials. Chapter 1 describes the role of Western European Union, which embodies a regional settlement, largely military in character. Western European Union authorizes the production of nuclear weapons by other member states on the continent of Western Europe. Chapter 2 looks into the United States program's relationship with that of the International Atomic Energy Agency. This chapter deals also with the reason for U.S. support for the development of international safeguard. Chapters 3 and 4 evaluate the function and peaceful purposes of the European Atomic Energy Community and the European Nuclear Energy Agency. Chapter 5 reviews the control of uranium, plutonium and associated facilities intended for peaceful purposes through the International Atomic Energy Agency. This book is of value to researchers and general readers who are interested in international efforts for arms control.

Systems Analysis in Ecology surveys the problems and techniques of systems analysis in ecology. The opening and closing chapters were written by the editor, the first to explain why systems analysis is needed in ecology and what is meant by the term, and the last to point out the implications of this new approach for the future development of ecology. The book opens with a discussion of the nature of systems analysis. This is followed by separate chapters on the complexity of ecological systems and problems in their study and management; the organization and analytical procedures required by a large ecological systems study; telemetry and automatic data acquisition systems; and surveillance of the activities of small mammals. Subsequent chapters deal with the analysis of bird navigation experiments; the analysis of determination in population systems; building models of complex ecological systems; mathematical tools for the design of better salmon fishery management systems; and the evolution of ecological research programs.

Advances in Oxytocin Research documents the proceedings of a symposium held by the Blair-Bell Research Society at the Royal College of Obstetricians and Gynecologists, London, England, on 1st May 1964. Oxytocin was chosen as the subject of the symposium due to recent important work on its physiology and pharmacology, and the availability of a new method of administering the drug for the induction of labor in women after extensive study in America, Europe, and Great Britain. The volume contains papers presented by during the two sessions held during the symposium. The first session on the physiology and pharmacology of oxytocin includes studies on the circulatory effects of oxytocin, release of oxytocin during parturition, and the release of oxytocin in domestic animals. The second session on clinical applications includes papers on the endocrine control of labour, clinical trials of buccal oxytocin, and tge oxytocin sensitivity test. Also included are the opening remarks by Sir Arthur Bell, President of the Blair-Bell Society and the Chairman’s Introduction at the beginning of each session.

The Control of Fertility

The Control of Fertility is concerned with the experimental control of fertility as a specific biological problem. It is, first of all, an attempt to summarize a collection of data hitherto either partially or not at all presented. Secondly, it attempts to indicate those avenues which hold promise for future investigation. Finally, it attempts an assessment of the implications of understandings and ignorances. The book opens with an account of the sequence of processes essential to successful sexual reproduction in mammals. This is followed by separate chapters on approaches to the inhibition of spermatogenesis, ovulation, fertilization, and free ovum development. Subsequent chapters deal with blastocyst development and implantation, biological activities of compounds affecting fertility, fertility control in men and women, the inhibition of ovulation, biological properties of ovulation inhibitors in human subjects, and effectiveness and acceptability of contraception.

Recent Advances in Aerosol Research: A Bibliographical Review presents a bibliographic review of advances in aerosol research covering the period from the beginning of 1957 to the end of 1962. Topics covered include chemical reactions, combustion, coagulation and diffusion, and adhesion of particles. References on filtration, evaporation and condensation, nucleation and growth, and laminar flow and impingement are also included. This volume is comprised of 19 chapters and begins by citing research on acoustic, ultrasonic, and shock wave effects, along with adhesion of particles, chemical reactions, combustion, coagulation and diffusion, and filtration. The following chapters deal with evaporation and condensation, nucleation and growth, laminar flow and impingement, generators, photophoresis, and the optics of aerosols. Other chapters focus on radioactivity, sampling instruments, sedimentation and fluid resistance, thermophoresis, and diffusiophoresis. The last chapter highlights turbulent flow and deposition of aerosols. This monograph will be a valuable resource for researchers and practitioners interested in aerosols.

Radiation, Radioactivity, and Insects focuses on the role of radiation and radioactivity in promoting the understanding of insects, including biochemistry, embryonic development, irradiation, and metabolism. The book first underscores the importance and dominance of insects in the animal kingdom, classification of insects, physiology and biochemistry, and embryonic development. The manuscript then examines the nongenetic effects of radiation, tagging, and insect control by irradiation. Topics include sex and genome number, nutritional status, mechanism of radiation damage, distribution and feeding studies, direct control by irradiation, and radiation effects. The publication takes a look at biochemistry, physiology, and insects and light, as well as amino acid metabolism, protein synthesis, permeability of the central nervous system, digestion and absorption, and elemental turnover. The manuscript then ponders on organophosphorus insecticides, chlorinated hydrocarbons, and miscellaneous insecticides. The book is a dependable source of data for entomologists, biologists, and readers who are interested in the role of radiation in advancing the understanding of insects.

River Pollution 2: Causes and Effects deals mainly with the causes of river pollution and the nature of the various kinds of pollution and their effects upon rivers. This book is an updated version of the first eight chapters of Aspects of River Pollution (first published early in 1957). Owing to the rapid development of the subject and the ever-increasing amount of literature devoted to it, some sections have been virtually rewritten, much new matter has been added, and minor alterations made throughout the text. This book begins with a review of the long history of river pollution, which can be traced back to ancient civilizations. Separate chapters deal with legal aspects of river pollution; the nature and effects of river pollution; the causes of river pollution; and uses of river water. Subsequent chapters cover the biochemical and physicochemical aspects of river pollution; the impact of river pollution on fishes; and biological aspects of river pollution.

Chronic Radiation Hazards: An Experimental Study with Fast Neutrons describes a large-scale experiment on the hazards to be expected from low and very low levels of chronic irradiation by fast neutrons. Fast neutrons may be an environmental hazard around nuclear reactors and some machines for accelerating particles, and it is therefore of practical as well as academic importance to get some idea of the likely ill-effects of chronic irradiation by fast neutrons. The book is organized into four parts. Part I describes the experimental design, including factors such choice of animal, choice of dose rate, observation of radiation effects, dose measurements, and energy of the neutrons. Part II deals with the measurement of fast neutron dose. Topics discussed include Interaction of neutrons with light elements; energy absorption due to fast neutrons; energy absorption due to gamma rays; and ionization-dose and ionization-flux relations for fast neutrons. Part III discusses the results of fast neutron irradiation while Part IV covers the relative biological efficiency of fast neutrons and gamma rays for chronic exposures.
