An extensive guide to the legionary fortresses of the Roman Empire, including locations, history, layout, and more. This is a reference guide to Roman legionary fortresses throughout the former Roman Empire, of which approximately eighty-five have been located and identified. With the expansion of the empire and the garrisoning of its army in frontier regions during the 1st century AD, Rome began to concentrate its legions in large permanent bases. Some have been thoroughly explored while others are barely known, but this book brings together for the first time the legionary fortresses of the whole empire. An introductory section outlines the history of legionary bases and their key components. At the heart of the book is a referenced and illustrated catalogue of the known bases, each with a specially prepared plan and an aerial photograph. A detailed bibliography provides up-to-date publication information. The book includes a website providing links to sites relevant to particular fortresses and a Google Earth file containing all of the known fortress locations.
This book is the second of two volumes that deal with discovery of chemical pathways of biosynthesis of natural products (secondary metabolites). The first volume covered the use of isotopes in biosynthetic research and the formation of enzyme cofactors and reduced polyketides. This second volume describes biosynthesis of aromatic (unreduced) polyketides, enzymes responsible for cyclization of terpenoids (isoprenoids), and biochemical generation of selected classes of alkaloids (prenylated tryptophan, tropane, pyrrolizidine). Knowledge of the pathways and the techniques to elucidate them opens the door to combinatorial biosynthesis as well as to the production of targeted pharmaceutical agents utilizing a combination of chemistry, molecular biology and protein biochemistry.
Vols. for 1963- include as pt. 2 of the Jan. issue: Medical subject headings.
Includes section, "Recent book acquisitions" (varies: Recent United States publications) formerly published separately by the U.S. Army Medical Library.
Due to the increasing importance of product differentiation and collapsing product life cycles, a growing number of value-adding activities in the industry and service sector are organized in projects. Projects come in many forms, often taking considerable time and consuming a large amount of resources. The management and scheduling of projects represents a challenging task, and project performance may have a considerable impact on an organization's competitiveness. This handbook presents state-of-the-art approaches to project management and scheduling. More than sixty contributions written by leading experts in the field provide an authoritative survey of recent developments. The book serves as a comprehensive reference, both, for researchers and project management professionals. The handbook consists of two volumes. Volume 1 is devoted to single-modal and multi-modal project scheduling. Volume 2 presents multi-project problems, project scheduling under uncertainty and vagueness, managerial approaches and a separate part on applications, case studies and information systems.
