This book introduces Planctomycetes bacteria and deals in detail with their unusual structure, physiology, genomics and evolutionary significance. It is a definitive summary of recent knowledge of this important distinctive group of bacteria, microorganisms which challenge our very concept of the bacterium. Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria, including verrucomicrobia and chlamydia, challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full diversity of how living cells can be organized internally. Unique among bacteria, they include species possessing cells with intracellular membrane-bounded compartments and a peptidoglycan-less cell wall, and bacteria such as the anammox organisms performing unique anaerobic ammonium oxidation significant for global nitrogen cycle.
An Introduction to Organic Geochemistry explores the fate of organic matter of all types, biogenic and man-made, in the Earth System. investigates the variety of pathways and biogeochemical transformations that carbon compounds can experience over a range of time scales and in different environments scope widened to provide a broad and up-to-date background - structured to accommodate readers with varied scientific backgrounds essential terminology is defined fully and boxes are used to explain concepts introduced from other disciplines further study aided by the incorporation of carefully selected literature references It investigates the variety of pathways and biogeochemical transformations that carbon compounds can experience over a range of time scales and in different environments.
Better understanding of life processes on a molecular level is the aim of Bioorganic Chemistry. Structure elucidation, synthesis of biomimetic models, theoretical and mechanistic concepts e.g. of enzyme action are the basic tools. The new series will bring together critical reviews on the progress in this field.

Current use of the ammonia oxidizing bacteria (AOB) within biological wastewater treatment system is incomplete due to limitations of current culture-based techniques. This book offers an overview of new nitrification technologies via the use of AOB in the removal of ammonia nitrogen from wastewater. The application of new approaches based on AOB leads to greater ammonia nitrogen removal and results in more efficient wastewater treatment.

In 1973, President Nixon halted new construction of public housing, claiming that the U.S. government had become "the biggest slumlord in history." Four decades earlier, in the depths of the Great Depression, strong political support for federally-subsidized low-income housing had resulted in the Housing Act of 1937. By the 1950s, growing criticism of the housing constructed by local authorities and prejudice against poor residents--particularly African Americans--fueled opposition to new projects. This book documents the lively and wide-ranging national debate over public housing from the New Deal to Nixon.
Isotopic studies combined with geochemical, lithological, mineralogical and palaeontological investigations have been widely used in reconstructing Cretaceous marine and continental environments. Furthermore stable and radiogenic isotope trends play an important role in the interpretation of the causes and consequences of biotic turnovers at stratigraphic boundaries as well as in global correlations.
