The study of biofilm considers the close association of micro-organisms with each other at interfaces and the consequent physiological adaptation to the proximity of other cells and surfaces. As such it is relevant to a variety of disciplines, including medicine, dentistry, bioremediation, biofouling, water technology, engineering and food science. Although the habitats studied, and their associated cellular communities, differ widely, some common elements exist such as method of attachment, coadhesion, regulation of biofilm phenotype and biofilm architecture. This book aims to distil the common principles of biofilm physiology and growth for all interested disciplines. It will appeal to the specialist biofilm researcher as well as to students wishing to introduce themselves to the topic.

Microbes are of key importance in the production, deposition and diagenesis of sediments. This volume provides a comprehensive overview of microbial sediments. It contains authoritative and stimulating contributions by distinguished authors that cover the field and set the scene for future advances. It deals with mats and biofilms, biosedimentary precipitates, fabrics and diagenesis in a wide range of sedimentary environments, and it examines the development of microbial sediments through time. It is designed for postgraduate researchers and professional scientists who require up-to-date information on the influence of microorganisms on sedimentation.

This book is an introduction to manifolds at the beginning graduate level. It contains the essential topological ideas that are needed for the further study of manifolds, particularly in the context of di?erential geometry, algebraic topology, and related ?elds. Its guiding philosophy is to develop these ideas rigorously but economically, with minimal prerequisites and plenty of geometric intuition. Here at the University of Washington, for example, this text is used for the ?rst third of a year-long course on the geometry and topology of manifolds; the remaining two-thirds focuses on smooth manifolds. Therearemanysuperbtextsongeneralandalgebraictopologyavailable. Why add another one to the catalog? The answer lies in my particular visionofgraduateeducation—itismy(admittedlybiased)beliefthatevery serious student of mathematics needs to know manifolds intimately, in the same way that most students come to know the integers, the real numbers, Euclidean spaces, groups, rings, and ?elds. Manifolds play a role in nearly every major branch of mathematics (as I illustrate in Chapter 1), and specialists in many ?elds ?nd themselves using concepts and terminology fromtopologyandmanifoldtheoryonadailybasis. Manifoldsarethuspart of the basic vocabulary of mathematics, and need to be part of the basic graduate education. The ?rst steps must be topological, and are embodied in this book; in most cases, they should be complemented by material on smooth manifolds, vector ?elds, di?erential forms, and the like. (After all, few of the really interesting applications of manifold theory are possible without using tools from calculus.

This paper describes the primary framework associating the four principal price indices in the system of economic statistics—the Producer Price Index (PPI), the Consumer Price Index (CPI), and the Export and Import Price Indices (XPI and MPI)—with the macroeconomic value aggregates they decompose into price and volume components. The paper begins by defining the basic algebra of price indices. It then discusses the definition of the value aggregates comprising the goods and services components of the System of National Accounts 1993 (1993 SNA). The paper concludes by briefly considering purchasing power parities and labor compensation indices.
