This book presents the statistical methods that are useful in the study of molecular evolution and illustrates how to use them in actual data analysis. Molecular evolution has been developing at a great pace over the past decade or so, driven by the huge increase in genetic sequence data from many organisms, the improvement of high-speed microcomputers, and the development of several new methods for phylogenetic analysis. This book for graduate students and researchers, assuming a basic knowledge of evolution, molecular biology, and elementary statistics, should make it possible for many investigators to incorporate refined statistical analysis of large-scale data in their own work. Nei is one of the leading workers in this area. He and Kumar have developed a computer program called MEGA, which has been sold for about $20 to over 1900 users. For the book, the authors are thoroughly revising MEGA and will make it available via FTP. The book also included analysis using the other most popular programs for phylogenetic studies, including PAUP, PHYLIP, MOLPHY, and PAML.

Explores the latest applications arising from the intersection of nanotechnology and microfluidics In the past two decades, microfluidics research has seen phenomenal growth, with many new and emerging applications in fields ranging from chemistry, physics, and biology to engineering. With the emergence of nanotechnology, microfluidics is currently undergoing dramatic changes, embracing the rising field of nanofluidics.This volume reviews the latest devices and applications stemming from the merging of nanotechnology with microfludics in such areas as drug discovery, bio-sensing, catalysis, electrophoresis, enzymatic reactions, and nanomaterial synthesis. Each of the ten chapters is written by a leading pioneer at the intersection of nanotechnology and microfluidics. Readers not only learn about new applications, but also discover which futuristic devices and applications are likely to be developed. Topics explored in this volume include: New lab-on-a-chip systems for drug delivery Integration of microfluidics with nanoneuroscience to study the nervous system at the single-cell level Recent applications of nanoparticles within microfluidic channels for electrochemical and optical affinity biosensing Novel microfluidic approaches for the synthesis of nanomaterials Next-generation alternative energy portable power devices References in each chapter guide readers to the primary literature for further investigation of individual topics. Overall, scientists, researchers, engineers, and students will not only gain a new perspective on what has been done, but also the nanotechnology tools they need to develop the next generation of microfluidic devices and applications.Microfluidic Devices for Nanotechnology is a two-volume publication, the first ever to explore the synergies between microfluidics and nanotechnology. The first volume covers fundamental concepts; this second volume examines applications.

A challenge for professionals involved in the cultural heritage sites in tropical environments, is the biodeterioration of stone. This volume discusses the types and causes of stone biodeterioration in hot and humid climates, and preventive and remedial treatments.

Natural resources are vital for meeting the food, livelihood and environmental security. It is now widely accepted that future of food, livelihood and environmental security depends upon the attention paid to conservation, sustainable development and management of natural resources. Natural resource management ties in with applied concepts such asmaximum sustainable yield (MSY) and optimum utilization. Every natural resource has its optimum utilization, or acceptable levels of use, which are established scientifically and according to which management authorities regulate its exploitation. Degradation of natural resources has been caused by a variety of social, economic, institutional and technological factors. Rapidly growing population, urbanisation and industrial activities have all resulted in considerable deterioration in the quality and quantity of natural resources. This book discusses both the principles and applications of an integrated approach to natural resources management. This book is compilation of various topical issues on the prime concerns of natural resource conservation in arable and non-arable lands, suitable land utilization planning soil-water resource conservation, diversification of crops and farming systems to ensure sustainable management
