"Collections: A Journal for Museum and Archives Professionals" is a multi-disciplinary peer-reviewed journal dedicated to the discussion of all aspects of handling, preserving, researching, and organizing collections. Curators, archivists, collections managers, preparators, registrars, educators, students, and others contribute.

This focus issue of the journal examines case studies from the field of photographic preservation and collections management. Guest Editor, Olivia Arnone, provides a history and context for the eponymous program based at the George Eastman Museum in Rochester, NY. Six amply-illustrated articles addressing this area of research follow.

This volume is part of the definitive edition of letters written by and to Charles Darwin, the most celebrated naturalist of the nineteenth century. Notes and appendixes put these fascinating and wide-ranging letters in context, making the letters accessible to both scholars and general readers. Darwin depended on correspondence to collect data from all over the world, and to discuss his emerging ideas with scientific colleagues, many of whom he never met in person. The letters are published chronologically: volume 24 includes letters from 1876, the year in which Darwin published Cross and Self Fertilisation in the Vegetable Kingdom, and started writing Forms of Flowers. In 1876, Darwin's daughter-in-law, Amy, died shortly after giving birth to a son, Bernard Darwin, an event that devastated the family. The volume includes a supplement of 182 letters from earlier years, including a newly discovered collection of letters from William Darwin, Darwin's eldest son.

"Volume I contains subjective reviews, specialized and novel technique descriptions by guest authors. Part 1 includes contributions on purely analytical techniques and Part 2 includes matters such as development of mass spectrometers, stability of ion sources, standards and calibration, correction procedures and experimental methods to obtain isotopic fractionation factors. Volume II will be available in 2005."--Publisher's website.

Soil is formed from physical and chemical weathering of rocks - processes described historically because they involve eons of time-by glaciation and by wind and water transport of soil materials, later deposited in deltas and loessial planes. Soil undergoes further transformations over time and provides a habitat for biological life and a base for the development of civilizations. Soil is dynamic -always changing as a result of the forces of nature and particularly by human influences. The soil has been studied as long as history has been documented. Numerous references to soil are found in historical writings such as Aristotle (384-322 B. c. ), Theophrastus (372-286 B. c. ), Cato the Elder (234-149 B. C. ) and Varro (116-27 B. c. ). Some of the earliest historical references have to do with erosional forces of wind and water. The study of soils today has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experienced. This has led to an increase in land degradation and desertification. Desertifica tion is largely synonymous with land degradation but in an arid land context. Deterioration of soil resources is largely human induced. Poverty, ignorance, and greed are the indirect causes of desertification. The direct cause is mismanage ment of the land by practices such as overgrazing, tree removal, improper tillage, poorly designed and managed water distribution systems, and overexploitation.

Advances in Natural Gas: Formation, Processing, and Applications is a comprehensive eight-volume set of books that discusses in detail the theoretical basics and practical methods of various aspects of natural gas from exploration and extraction, to synthesizing, processing and purifying, producing valuable chemicals and energy. The volumes introduce transportation and storage challenges as well as hydrates formation, extraction, and prevention. Volume 5 titled Natural Gas Impurities and Condensates Removal comprehensively discusses the characteristics and properties of natural gas condensates and dehydrated non-acidic impurities. The book describes related environmental challenges, removal standards, policies and regulations as well as economic assessment. It covers particulates (such as aerosols, arsenic, etc.) and condensates removal techniques from natural gas as well as mercury, nitrogen and helium removal from natural gas by absorption, adsorption and membrane-based processes. - Introduces different impurities and condensates of natural gas with their characteristics - Includes common methods for particulates and condensates removal from natural gas such as adsorption, absorption and cryogenic techniques - Describes various membrane technologies for particulates and condensates removal from natural gas

Collection of Problems in Physical Chemistry provides illustrations and problems covering the field of physical chemistry. The material has been arranged into illustrations that are solved and supplemented by problems, thus enabling readers to determine the extent to which they have mastered each subject. Most of the illustrations and problems were taken from original papers, to which reference is made. The English edition of this book has been translated from the manuscript of the 2nd Czech edition. It has been changed slightly in some places and enlarged on in others on the basis of further experience gained in teaching physical chemistry at the Institute of Chemical Technology in Prague. The book begins with illustrations and problems on the atomic structure and the fundamentals of quantum mechanics. Subsequent chapters cover the kinetic theory of ideal gas; fundamentals of thermodynamics; states of matter; phase equilibrium; chemical equilibrium and third law of thermodynamics; electrochemistry; reaction kinetics; surface phenomena and colloidal systems; and molecular structure and physical properties.
