Biodegradation and Durability of Materials Under the Effect of Microorganisms

By: Sergei A. Semenov,Klara Z. Gumargalieva,Gennadiĭ Efremovich Zaikov

This volume in the book series New Concepts in Polymer Science deals with the damaging effects, which microorganisms such as bacteria, fungi, etc. can have on a range of materials in machinery. The book aims to provide theoretical notions about the mechanisms of material damaging by microorganisms under operation conditions as well as to give recommendations for protection of technical articles and machinery.This monograph consists of the following topics: finding of kinetic regularities, analytical models and quantitative indices for stages material biodamaging; study of influence of properties of materials, features of microorganisms, temperature, humidity and other factors on interaction between a material and a biodestructor; and, compilation of guidelines to determine and forecast biological resistance (bioresistance) of materials, development of means and methods for their protection as well as estimates of their efficiency.This monograph will be of value and interest to researchers and engineers working in fields in which materials are subject to active microbiological aging and destruction.

Statistics of Knots and Entangled Random Walks

By: Sergei K. Nechaev

In this book, the author announces the class of problems called ?entropy of knots? and gives an overview of modern physical applications of existing topological invariants.He constructs statistical models on knot diagrams and braids using the representations of Jones-Kauffman and Alexander invariants and puts forward the question of limit distribution of these invariants for randomly generated knots. The relation of powers of corresponding algebraic invariants to the Lyapunov exponents of the products of noncommutative matrices is described. Also the problem of conditional joint limit distributions for ?brownian bridges? on braids is discussed. Special cases of noncommutative groups PSL(2, R), PSL(2, Z) and braid groups are considered in detail.In this volume, the author also discusses the application of conformal methods for explicit construction of topological invariants for random walks on multiconnected manifolds. The construction of these topological invariants and the monodromy properties of correlation function of some conformal theories are also discussed.The author also considers the physical applications of ?knot entropy? problem in various physical systems, focussing on polymer

The Black Sea Encyclopedia

By: Sergei R. Grinevetsky,Igor S. Zonn,Sergei S. Zhiltsov,Aleksey N. Kosarev,Andrey G. Kostianoy

This publication is devoted to the natural feature – the Black Sea and its littoral states. At the same time the Azov Sea is also considered here. This region is the focus of many geopolitical, economic, social and environmental issues that involve not only the countries coming out to the Black and Azov Seas, but other world countries, too. This publication contains over 1500 articles and terms providing descriptions of geographical and oceanographic features, cities, ports, transport routes, marine biological resources, international treaties, national and international programs, research institutions, historical and archaeological monuments, activities of prominent scientists, researchers, travelers, military commanders, etc. who had relation to the Black Sea. It includes a multi-century chronology of the events that became the outstanding milestones in the history of development of the Black Sea – Azov Sea region.
