SCIENCE teachers, TEACHER training, CHEMISTRY education, HIGH schools, OCCUPATIONAL training, SECONDARY education, EFFECTIVE teaching, HIGH school students, and EDUCATION research
The article discusses studies about developments in professional training of science teachers in high schools in the U.S. A chemistry teacher should have as a minimum, college courses in general inorganic chemistry, organic chemistry, qualitative analysis, quantitative analysis and physical chemistry. Organic chemistry is studied because of the basic principles and general information involved and the important role organic substances play in modern life. One of the conclusions reached by the Committee on Preparation of High School Chemistry teachers is that more extensive training and other sciences is urgently needed in many cases and these needs should be met either by decreasing the requirements in educational course, by increasing the number of credits required for graduation.
SCIENTISTS, BIOLOGISTS, BIOLOGICAL research, SCIENTIFIC community, and OXYTETRACYCLINE
The article presents information on scientist Ben A. Sobin and his research achievements. He was born in Cleveland, Ohio, in 1912 and his graduate education took place at Ohio State University. He specialized in chemistry, organic chemistry, bacteriology and biochemistry. Professionally he worked in various organizations and his career with Pfizer Inc. began as chief of biologies control where he attained success in research assignment. One of them was the preparation of the first samples of Terramycin under Sobin's direction.
SEDIMENTATION & deposition research, OCEAN bottom, and CARBONATE minerals
Discusses the mechanism underlying the relative deposition rates of organic carbon and calcite to the sea floor. Effect of total calcite concentration on the specific depth at which calcite dissolves; Control of atmospheric carbon dioxide by ocean carbonate chemistry; Organic carbon degradation in the sediments.
Published data and the results of the authors' investigations on the electrochemical conversion of carbon, sulfur, and nitrogen oxides and freons into valuable organic products are reviewed. Considerable attention is paid to the probable mechanisms of such processes, the role and position of the radical-ions and free radicals in them, and the effect of the structure of the reagents, the electrolysis conditions, and other factors on the composition and yield of the products. The problems of developing this promising process, which lies at the junction between physical chemistry, organic chemistry, and ecology, are explored. [ABSTRACT FROM AUTHOR]

Since mining is a basic and essential industry supplying raw materials for medicines; building materials for homes, schools, hospitals, commerce, roads; fuels for heating and energy; metals for transportation (cars, aircraft and ships), machinery, communications infrastructure and other conveniences, it cannot be done away with as some extremist environmentalists would like. What would modern life be without minerals?Miners are the harvesters of the earth's fruits. To reap those fruits, the earth must be plowed up. After harvesting, the plowed fields can be reclaimed and restored to pristine, natural beauty with only temporary disturbance to the earth.Reclamation of surface mines can profitably utilise the void space for burial of society's solid wastes while restoring the mined land surfaces to their original beauty or utility. Industry and environmentalists should rejoice.
This book is a synthesis of two of Hudlicky's earlier books outlining the many unpredictable properties of fluorine and its compounds that are not analogous to the properties of any other halogens and their compounds. It is divided into two separate sections, the first presenting peculiar reactions as problems to be solved. Each reaction can be analyzed in the lab without the help of the second section, however if a solution is not easily reached, the second section provides discussion of the problems, outlining the products of the reactions and their mechanisms. Among the 105 reactions outlined are the introduction of fluorine into organic molecules, reduction and oxidation of fluorine compounds, reactions of fluorocompounds with halogens and their derivatives, nitration, acid catalyzed reactions, organometallic syntheses, and pyrolyses. The reactions are documented in the experimental material of the earlier volumes and will be important background knowledge for anyone working in organic chemistry.

Solid-phase synthesis and Peptides--Synthesis
In the years since the publication of Atherton and Sheppard's volume, the technique of Fmoc solid-phase peptide synthesis has matured considerably and is now the standard approach for the routine production of peptides. The basic problems at the time of publication of this earlier work have now for the most part, been solved. As a result, innovators in the field have focussed their efforts to develop methodologies and chemistry for the synthesis of more complex structures. The focus of this new volume is much broader, and covers the essential procedures for the production of linear peptides and more advanced techniques for preparing cyclic, side-chain modified, phospho- and glycopeptides. Many other methods also deserving attention have been included: convergent peptide synthesis; peptide-protein conjugation; chemoselective ligation; and chemoselective purification. The difficult preparation of cysteine and methionine-containing peptides is also covered, as well as methods for overcoming aggregation during peptide chain assembly. Many of the techniques developed for the production of large arrays of peptides by parallel synthesis, such as t-bag, SPOT and PIN synthesis, have naturally been included. Finally, a survey of available automated instrumentation has also been provided.
Polymers, Crystallization, Crystalline polymers, and Chemical equilibrium
First published in 2002, from an original 1964 edition, in the Crystallization of Polymers, 2nd edition Leo Mandelkern provides a self-contained treatment of polymer crystallization. All classes of macromolecules are included and the approach is through the basic disciplines of chemistry and physics. The book discusses the thermodynamics and physical properties that accompany the morphological and structural changes that occur when a collection of molecules of very high molecular weight are transformed from one state to another. Volume 1 is a presentation of the equilibrium concepts that serve as a basis for the subsequent volumes. In this volume the author shows that knowledge of the equilibrium requirements is vital to understanding all aspects of the polymer crystallization process, and the final state that eventually evolves. This book will be an invaluable reference work for all chemists, physicists and materials scientists who work in the area of polymer crystallization.
Assuming no previous knowledge of polymers, this book provides a general introduction to the physics of solid polymers. Covering a wide range of topics within the field of polymer physics, the book begins with a brief history of the development of synthetic polymers and an overview of the methods of polymerisation and processing. In the following chapter, David Bower describes important experimental techniques used in the study of polymers. The main part of the book, however, is devoted to the structure and properties of solid polymers, including blends, copolymers and liquid crystal polymers. With an approach appropriate for advanced undergraduate and graduate students of physics, materials science or chemistry, the book includes many worked examples, and problems with solutions. It will provide a firm foundation for the study of the physics of solid polymers.
