Chromatography and Electrophoretic Techniques, Volume II: Zone Electrophoresis presents a number of methods, all based on zone electrophoresis, which has been carried out on commercially available apparatus offering many advantages to the majority of laboratories. This book is composed of six chapters and begins with discussions on the principles, instrumentation, and applications of paper electrophoresis at low voltages, such as voltages not exceeding 300-400 volts or a potential drop of not more than 10 volts/cm in the direction of migration. The next chapter describes the general experimental methods for the separation of abnormal hemoglobins and surveys the application of paper electrophoresis to the final identification of a hemoglobin variant. The remaining chapters deal with the principles, apparatus, reagents, and applications of other zone electrophoretic techniques, including cellulose acetate; agar gel, starch block, starch gel, and sponge rubber; high voltage paper; and continuous electrophoresis. This book will prove useful to analytical chemists and biologists.

The Chemistry of Lignin provides a critical review of the literature published from 1949 to 1958. This book provides information pertinent to the fundamental aspects of lignin chemistry. Organized into 27 chapters, this book begins with an overview of the derivatives that are prepared for the characterization of the mother substance. This text then examines the various kinds of lignin and biosynthetic lignin-like products, which have been characterized by their behavior toward oxidation with nitrobenzene and alkali. Other chapters consider the morphological distribution of lignin in the wood fiber and the place of origin of lignin precursors and of the lignification process. This book discusses as well the formation or biosynthesis of lignin in plants and reviews the structure, isolation, and biosynthesis of lignin. The final chapter deals with producing lignin by the action of enzymes. This book is a valuable resource for lignin chemists, scientists, research workers, and botanists.

Hydrogen Bonding covers the papers presented at the Symposium on Hydrogen Bonding, held at Ljubljana on July 29 to August 3, 1957. The book focuses on the developments, processes, approaches, methodologies, and reactions involved in hydrogen bonding. The selection first offers information on the structure of water; function of hydrogen bond in solids and liquids; and study of hydrogen bonds by neutron diffraction. The text then takes a look at x-ray and neutron studies of hydrogen bonding; x-ray studies of ammonium bifluoride, potassium hydrogen maleate, theophylline, and caffeine; and isotope effect in relation to bond length in hydrogen bonds in crystals. The publication ponders on proton magnetic resonance measurements of hydrogen bonding; interpretation of nuclear magnetic resonance shifts in hydrogen bonding; nuclear resonance investigation of hydrogen bonding; and infrared spectroscopy and hydrogen bonding — band-widths and frequency shifts. The book then examines the tunneling of protons as a cause of the splitting of hydroxyl stretching bands; infrared spectroscopic study of H-bonding and of metal-element bonding; and effect of hydrogen bond formation on the electronic spectra of phenolic substances. The selection is a vital source of information for readers interested in hydrogen bonding.

River Pollution 1: Chemical Analysis discusses methods of detecting and determining the various forms of pollution and the interpretation of results. It aims to provide a chemical background for, and supplement to, the information on analytical methods, and to review critically other methods which may be useful in certain circumstances for research, control work, and field tests. The book begins with a description of river surveys, and physical and chemical methods for determining river pollution. Separate chapters cover methods to determine the presence of dissolved oxygen, combined nitrogen, sulfur compounds, carbon dioxide, free chlorine, metallic contaminants, and carbon compounds. Subsequent chapters discuss the estimation of less important substances which may sometimes be encountered in pollution problems; and the significance of chemical and physical tests and the interpretation of the results of an analysis. This book is intended for those interested in chemical analysis as applied to river pollution problems, sewage, and trade wastes.

Analytical Elements of Mechanics

Analytical Elements of Mechanics, Volume 1, is the first of two volumes intended for use in courses in classical mechanics. The books aim to provide students and teachers with a text consistent in content and format with the author’s ideas regarding the subject matter and teaching of mechanics, and to disseminate these ideas. The book opens with a detailed exposition of vector algebra, and no prior knowledge of this subject is required. This is followed by a chapter on the topic of mass centers, which is presented as a logical extension of concepts introduced in connection with centroids. A theory of moments and couples is constructed without reference to forces, these being mentioned only in illustrative examples. This is done because it eventually becomes necessary to apply the theory to systems of vectors which are not forces, such as momenta and impulses. Equilibrium is discussed in the final chapter, preceded by extended examination of the concept of force.

Ultracentrifugation in Biochemistry

Ultracentrifugation in Biochemistry discusses the fundamental aspects of ultracentrifugation. The book begins with a sketch of the field, highlighting some of the principal developments. Following this is a chapter that discusses ultracentrifugation in general terms and describes the division of the field into three major areas. The subsequent chapter deals with developments of the experimental aspects of the field such as improvements in the instrument itself, cells, rotors, measurement, and control of temperature, and the various optical systems. The remainder of the book discusses the fundamental principles of sedimentation velocity, transient states, and sedimentation equilibrium. A section is also included which deals with interpretation of sedimentation data in terms of hydrodynamic models, charge effects, and interactions in multicomponent systems. This book is likely to become an indispensable companion to the laboratory worker who is planning and conducting an ultracentrifuge run for almost any purpose. It should also be of fundamental value to the thoughtful student or investigator who wants to know the present state of knowledge in the field, both experimental and theoretical.
