The main driving force behind the development of new applications for chitin and its derivative chitosan lies with the fact that these polysaccharides represent a renewable source of natural biodegradable polymers. Since chitin is the second most abundant natural polymer, academic as well as industrial scientists are faced with a great challenge to find new and practical applications for this material. This book provides an examination of the state of the art, and discusses new applications as well as potential products. Applications of Chitin and Chitosan deals almost exclusively with applications. Previous books in the field have devoted less than 30% of their material to commercial or medical uses.
In the past thirty years, substantial progress has been made on fundamental and applied research in chitosan technology. One of the driving forces behind this rapid development has been the decrease in the supply of natural resources. At the same time there has been an increased realization that there are abundant alternative bioresources. Two factors-economics and versatility-have also stimulated interest in chitosan's utilization in various fields. Chitin and chitosan derivatives have applications in fields that range from fertilizers to pharmaceuticals. Chitosan is no longer just a waste by-product from the seafood processing industry. This material is now being utilized by industry to solve problems and to improve existing products, as well as to create new ones.
Applications of Chitin and Chitosan is illustrated with over 100 photos, charts, graphs and figures and more than 40 tables.
Applications of Chitin and Chitosan will be of interest to industrial personnel involved in bioprocessing as well as bioengineering students, specialists in the biomedical and biopharmaceutical industry, biochemists, food engineers, environmentalists, and microbiologists and biologists who specialize in chitosan technology.

Many countries experience lack of harmony among economic development, environmental management and human health. As a consequence, public health, the integrity of ecosystems, and the efforts to reach environmental sustainability, have been adversely affected. The complexity, frequency and magnitude of those impacts is increasingly parallel to the technological revolution, rising population, and increasing per capita consumption. The burden of the concerns about how humans inflict natural and man-made enclaves tends to rely in highly industrial societies. However, many of the world environmental alterations are been achieved by non-industrial societies. This book examines and discusses multidisciplinary aspects of the impacts that humans had on the physical environment, the biota, and human health, focusing on the scenario of developing and under developing countries. Among the areas covered are environmental degradation, pollution, occupational health, risk management, epidemiology and toxicology. This book will help scientists, resource managers, administrators, educators, policy makers and college students interpret that risk management and the advancement of research in sustainable development is of utmost importance for all parties involved in seeking solutions for the protection of natural and anthropogenic systems, and human health.

Consolidating and expanding current, fundamental notions of virology and animal cell cultivation, this practical reference examines the development of insect cell culture techniques for the production of recombinant proteins and insect pathogenic viruses.;Resolving on-the-job problems such as sparging cell damage and reduced infectivity cells, Insect Cell Culture Engineering: includes special introductory material as well as background information on insect pathogenic viruses, the molecular biology of baculoviruses and bioreactor design; offers advice on how to save time when deciding which insect cell line, bioreactor and medium to exploit; discusses the preparation of mathematical modelling in animal cell culture; addresses the concerns associated with insect cell immobilization and the use of serum-free culture media; provides insights into the protective effects of polymer additives and insect cell gene expression in pharmaceutical research; and analyzes process scale-up and reactor design.;Bridging the gap between laboratory research and pilot plant scale insect culture/baculovirus technology, Insect Cell Culture Engineering is designed as a reference for biochemical and bioprocess engineers, bioprocess technologists, biochemists, molecular and cell biologists, microbiologists, and upper-level undergraduate and graduate students in these disciplines.

Expansive soils are a worldwide problem. The estimated damage to buildings, roads and other structures built on expansive soils exceeds fifteen billion US dollars annually. With their ability to swell and shrink in relation to the environment's water content, expansive soils are considered as geonatural hazards and form a challenge to geotechnical and construction engineers. To address the problems associated with these soils, this edited book provides expert contributions on the recent advances in the characteristics and treatment of expansive soils as well as an evaluation of and remedial measures suggested for structures built on expansive soils. Expansive Soils: Recent Advances in Characterization and Treatment provides the reader with easy and specific access to the information needed. Containing contributions by 52 experts from 22 countries, it gives a truly worldwide perspective of the problems and solutions associated with expansive soils. It is a valuable reference for engineers, researchers and (graduate) students working on expansive soils, soil improvement and foundation engineering.

Economic growth is a major source of wealth creation at the national and international level. It elevates a nation's standard of living as well as being able to lift it out of poverty. With suitable guidance on population growth, fiscal soundness, environmentally sustainable development and resource use, an acceptable distribution of income and a constant rate of technical progress, economic growth will always have a quantitative, as well as a qualitative dimension, both of which improve general living conditions and individual growth. This book argues that a key driver of economic growth among nations or regional economic entities is an intrinsic, ongoing, perpetual and historically observable rivalry to propel a state's standing, prestige, power and economic performance through getting ahead of or not to fall too much behind its rivals in a pecking order.
