Sedimentation as a Three-Component System describes the most common styles of deposition in marine environments as they relate to sediment composition.Three components, organic matter, carbonate, and siliciclastic sediment, maysettle concurrently, but at different rates, intermixing on the sea floor to form a particular sediment composition. A change in the flux of one component is capable of relatively diluting or concentrating theother two components, which can be expressed in the characteristic ratio of organic carbon to carbonate in the resulting sediment. The basic concept of this book is to address organic carbon-carbonate associations in terms of depositional inputs and time spans. In addition, the three-component system describes organic carbon changes related to major facies transitions. Examples include models of the genesis of carbonaceous sediments, with their various laminated to bioturbated lithotypes, and numerical organic carbon prediction.

Analytical ultracentrifugation is one of the most powerful solution techniques for the study of macromolecular interactions, to define the number and stoichiometry of complexes formed, and to measure affinities ranging from very strong to very weak and repulsive. Building on the data analysis tools described in the volume Sedimentation Velocity Analytical Ultracentrifugation: Discrete Species and Size-Distributions of Macromolecules and Particles, and the experimental and instrumental aspects in the first volume Basic Principles of Analytical Ultracentrifugation, the present volume Sedimentation Velocity Analytical Ultracentrifugation: Interacting Systems is devoted to the theory and practical data analysis of dynamically coupled sedimentation processes. This volume is designed to fill a gap in biophysical methodology to provide a framework that builds on the fundamentals of the highly developed traditional methods of analytical ultracentrifugation, updated with current methodology and from a viewpoint of modern applications. It will be an invaluable resource for researchers and graduate students interested in the application of analytical ultracentrifugation in the study of interacting systems, such as biological macromolecules, multi-protein complexes, polymers, or nanoparticles.

Mathematical Theory of Sedimentation Analysis presents the flow equations for the ultracentrifuge. This book is organized into two parts encompassing six chapters that evaluate the systems of reacting components, the differential equations for the ultracentrifuge, and the case of negligible diffusion. The first chapters consider the Archibald method for molecular weight determination; pressure-dependent sedimentation; expressions for the refractive index and its gradient; relation between refractive index and concentration; and the analysis of Gaussian distribution. Other chapters deal with the basic equations for three-component systems, the extension of the Archibald method to multicomponent systems, and the case of independent sedimentation and diffusion. These topics are followed by a presentation of the extrapolation procedures due to Oth and Desreux. The last chapters are devoted to the examination of the Johnston-Ogston effect and sedimentation with a differential boundary. The book can provide useful information to chemists, physicists, students, and researchers.

Computerized modeling is a powerful tool to describe the complex interrelations between measured data and the dynamics of sedimentary systems. Complex interaction of environmental factors with natural variations and increasing anthropogenic intervention is reflected in the sedimentary record at varying scales. The understanding of these processes gives way to the reconstruction of the past and is a key to the prediction of future trends. Especially in cases where observations are limited and/or expensive, computer simulations may substitute for the lack of data. State-of-the-art research work requires a thorough knowledge of processes at the interfaces between atmosphere, hydrosphere, biosphere, and lithosphere, and is therefore an interdisciplinary approach.

Analytical ultracentrifugation (AUC) can supply rich information on the mass, shape, size distribution, solvation, and composition of macromolecules and nanoscopic particles. It also provides a detailed view of their reversible single- or multi-component interactions over a wide range of affinities. Yet this powerful technique has been hard to mast

Polymer Fractionation focuses on the processes, reactions, and transformations involved in polymer fractionation, including chromatography, titration, and sedimentation. The selection first offers information on theoretical considerations and fractional precipitation. Topics include polydispersity of high polymers, phase relations for polydisperse systems, fractionation theory and efficiency, and fractionation by solvent evaporation. The manuscript then takes a look at fractional solution, chromatographic fractionation, and gel permeation chromatography. The book elaborates on thermal diffusion and turbidimetric titration, as well as methods of fractionation, studies of the variables, outline of the method and range of application, and elaboration of the method. The text then ponders on sedimentation, isothermal diffusion, and summative fractionation. Discussions focus on mathematical interpretation of summative data, experimental methods for the determination of diffusion constants, and methods for the determination of the diffusion coefficient distribution. The selection is a valuable source of information for readers interested in polymer fractionation.
