Deposition and aggregation of small solid particles are encountered in many natural and industrial environments. Whether it be deposition of particles onto a surface immersed in a liquid suspension or aggregateion of individual particles, these processes are of enotmous significance. They are vital to the manufacture of magnetic tape, purification of water using packed bed filters, selective capture of solids, cells and macromolecular species, and many other applications.This book presents a unified approach to the measurement, modelling and simulation of these processes, bringing together the disciplines of colliod and surface chemistry, hydrodynamics, and experimental and computational methods. It will be required reading for graduates working in process and environmental engineering, postgraduates involved in industrial R & D and for all scientists wishing to gain a more detailed and realistic understanding of process conditions in these areas.

Glycoconjugate Research, Volume I contains the proceedings of the Fourth International Symposium on Glycoconjugates, held in Woods Hole, Massachusetts, in September 1977. Contributors focus on the state of knowledge in the field of glycoconjugates ranging from polysaccharides and glycoproteins to glycolipids, proteoglycans, and all their varieties in plants, animals, and microorganisms. This text is organized into three sections and consists of 87 chapters. After an introductory chapter where the use of glycosidases for the structural analysis of complex carbohydrates is described, the discussion turns to other methods used for elucidating the structure of complex carbohydrates. The chapters that follow focus on the primary structure and conformation of glycans that are N-glycosically linked to peptide chains; isolation of monofuco-disialoganglioside from human and bovine brains; and partial chemical characterization of activated peptides isolated from a single cell suspension of rat colonic secretory cells. The last two sections explore cartilage proteoglycans and the structure-function relationships of glycoconjugates, touching on topics such as link proteins; the biochemical aspects of malignancy in human chondrosarcomas; defensive response of plants to a microbial oligosaccharide with a pheromone-like activity; and the interaction of saccharides with ricin. This book is intended for students and practitioners of chemistry and biochemistry; biology and microbiology; and physiology.

Glycoconjugate Research, Volume II contains the proceedings of the Fourth International Symposium on Glycoconjugates held in Woods Hole, Massachusetts in 1977. The papers explore the biosynthesis and regulation of glycoconjugates, particularly those of cell membranes, and glycolipid storage diseases. This volume is comprised of 95 chapters divided into three sections. After reviewing the regulatory mechanisms underlying glycoprotein synthesis, it turns to enzymic modifications of sialic acids in the course of glycoconjugate biosynthesis. The following chapters focus on the biosynthesis and characterization of lipid-linked sugars in the outer membrane of liver mitochondria; effect of bacitracin on the biosynthesis of dolichol derivatives in calf pancreas microsomes; secretion of proteoglycans by chondrocytes; and heterogeneity of arterial proteoglycans. The biosynthesis of elastin by chondroblasts in monolayer cultures is also considered, along with the phosphorylation of proteoglycans in human articular cartilage. The final chapter describes a double-antibody radioimmunoassay for soluble and cell-surface blood group Ii antigens. This book will be a useful resource for biochemists.

This extensively revised and updated second edition of The Neoplatonists provides a valuable introduction to the thought of the four central Neoplatonist philosophers, Plotinus, Porphyry, Proclus and Iamblichus.

Compelling stories of fatherhood from the popular NPR radio show

From the popular radio series This I Believe comes this touching and thought-provoking compilation of original essays on one of the most fundamental of human relationships-fatherhood. It is a relationship filled with joy and heartbreak, love and anger, lessons learned, and opportunities missed.

The stories in this collection are engaging and meaningful. Some are reverential and loving; some are sad and clouded by yearning, loss, and regret: You''ll read reflections from expectant and new dads, full of optimism, as well as from longtime parents who, through the distance of time, are able to reflect on their successes and failures as fathers.

We also hear from children (some young and some well into adulthood) writing about their fathers. They honestly and openly introduce us to the men who shaped them, sometimes in surprising ways. They talk about the fathers they want to emulate, the mistakes they hope to avoid repeating, and the wisdom they realized they''ve gained.

This I Believe: On Fatherhood offers a compelling portrait of the diverse range of experiences and beliefs related to the father-child relationship. With personal insights and inspiration, this collection makes a wonderful gift for long-time fathers, new fathers, and fathers-to-be.
