Natural resources not only contribute to overall growth of the economy but also help reduce poverty by providing employment and food security to populations on the continent, and is thus the most inclusive growth sector of the economy of Asian countries. Global weather and climate studies are also increasingly being considered a vital source of information to understand the earth's environment, in particular in the framework of weather and climate studies, land use transformation and human influence across these areas. Satellite earth observing systems provide a unique tool to monitor these changes. This book includes significant and up to date contributions in the field of sustainable natural resources conservation across the globe. While the range of applications and innovative techniques is constantly increasing, this book provides a summary of key case studies where satellite data offers critical information to help understand the causes and effects of those environmental changes, allowing us to reflect on how to minimize their negative impacts. This book is of interest to researchers and practitioners in the field of remote sensing, geographical information, meteorology, and environmental sciences. Scientists and graduate to post-graduate-level students in environmental science will also find valuable information in this book.

This is a graduate-level introduction to quantitative concepts and methods in the science of living systems. It relies on a systems approach for understanding the physical principles operating in biology. Physical phenomena are treated at the appropriate spatio-temporal scale and phenomenological equations are used in order to reflect the system of interest. Biological details enter to the degree necessary for understanding specific processes, but in many cases the approach is not reductionist. This is in line with the approach taken by physics to many other complex systems.The book bridges the gap between graduate students¿ general physics courses and research papers published in professional journals. It gives students the foundations needed for independent research in biological physics and for working in collaborations aimed at quantitative biology and biomedical research. Also included are modern mathematical and theoretical physics methods, giving the student a broad knowledge of tools that can shed light on the sophisticated mechanisms brought forth by evolution in biological systems. The content covers many aspects that have been the focus of active research over the past twenty years, reflecting the authors' experience as leading researchers and teachers in this field.

The monograph is based on the research and training activities in the Western Pacific Ocean Region within the umbrella of UNESCO/IOC-Sub-Commission for the Western Pacific Region. The results of these activities are compared to cases from other tropical and subtropical regions on this planet to make the knowledge applicable to global aspects of sustainability of coral reef ecosystems. In this monograph, we examine the coral reefs from viewpoint of multidisciplinary approaches, including, environmental impacts, coral biology and system ecology, biogeochemical cycles and processes that drive the material and energy flow through the food web, as well as the proxies in geochemistry that have been used to track the responses of coral reefs to the changing climate and human perturbations. Although this study is focused on the Western Pacific Ocean, the Western Pacific Ocean is so large and diverse that most reef environment types on this planet are located within it. Therefore, knowledge gained in this study is relevant to the application of coastal management in practice as well as in the teaching classes on the interactions between coral reef ecosystems with changing environments.

This Monograph explains the statistical theory behind the National Forest Inventory (NFI) data collection and compares different methods for modelling and inventory design. The author also explains how natural uncertainty in measurement and modelling can affects the results. Forests, as dynamic systems, are influenced by many unpredictable factors over time. Therefore, readers can use this book to develop the right framework of expectations, when using NFI data.The chapters give an outlook on traditional methods like sample plots, but also consider newer approaches like remote sensing. By merging these different techniqes, NFI datasets can become more reliable and facetted. One of the most contemporary developments in the field, is the use of continuous plots that offer live data at all times. Whether this data should be open to the public, is another discussion point that the author addresses.Offering a perspective from Estonia, readers will find practical examples for all discussed methods. This bridge from theory to practice, makes the volume a useful resource for scientists and decision makers in the forestry sector.  

This volume explores multiple methods and approaches used to generate human brain and neuroretinal organoids to address fundamental questions in human brain research. The chapters in this book cover topics such as self-organizing brain organoids with ventricles amenable to injection and electroporation; visualization of 3D organoids though the latest advancements in microscopy; generation of 3D retinal tissue with physiologically competent, light-sensitive photoreceptors; modeling brain tumors using genetically edited brain organoids; and brain organoids as a model to study Zika virus and SARS-CoV-2 infections. In the Neuromethods series style, chapters include the kind of detail and key advice from the specialists needed to get successful results in your laboratory.  Comprehensive and cutting-edge, Brain Organoid Research is a valuable resource for researchers at various levels of learning, ranging from undergraduate students, early researchers, and advanced laboratories. This book aims to be instrumental in moving this developing field forward.

This volume details experimental protocols to study structure and function of hepatocytes in vivo and in vitro, and for characterizing heterogeneity and plasticity of hepatocytes in healthy and in injured liver. Chapters guide readers through separating hepatocyte subfractions, characterizing the heterogeneity, novel culture systems, hepatocyte-like cells from human pluripotent stem cells, analyzing drug metabolism, monitoring protein sorting, manipulating gene expression, and methods for expanding primary hepatoblastoma and identifying hepatocellular carcinoma subtypes. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Hepatocytes: Methods and Protocols aims to provide techniques to further understand molecular mechanisms involved in the regulating hepatocyte functions and underlying liver diseases.

Intelligent Design goes well beyond the evolution debate. This book explores the science of this vast subject from the universe to life as well as going down to cells and DNA. It argues that the origin of first life, complexities of a cell, unparallel information system in DNA and many perfect systems seen in all life can only come from intelligence. It also draws evidence from lesser explored topics such as the brain- the most complex in the universe, power of the zygote, superior animal features, phylogenetics, microbiome, development of sexes in new species, physiology and fine-tuning of over 200 parameters in the universe, solar system, the earth as well as in the environment needed for life. It dissects fallacies and limitations of Darwinism falling well short of the biological complexities of all life, while agreeing with microevolution, which is a drop in the ocean of macroevolution. It concludes the impossible task of producing 8.7 million species with just two mechanisms of Darwinian theory namely random mutations and natural selection. Evidenced by purpose and fine-tuning at every level of complexity, this book gives proof of Intelligent Design based on undisputable mathematical probabilities.
