Methods in Plant Biochemistry, Volume 1: Plant Phenolics reviews current knowledge about techniques used in the analysis of the biochemistry of plant polyphenols and their importance in the agricultural and food industries. It looks at the application of these techniques in the fractionation of cellular constituents, isolation of enzymes, electrophoretic separation of nucleic acids and proteins, and chromatographic identification of the intermediates and products of cellular metabolism. Organized into 15 chapters, this book opens with an overview of the general procedures and measurement of total phenolics, from detecting phenolic substances in crude plant extracts to determining which classes they belong to and the quantitative estimation of total phenol. The reader is introduced to the chemistry, structural variation, function, and distribution of each class of plant phenolics and, in a few cases where this is practicable, detailed listings of known derivatives are given. Most chapters focus on chromatographic separations and high performance liquid chromatography (HPLC), along with thin layer and paper Rf values with HPLC retention times and NMR spectroscopy. The book also outlines the procedures for the extraction, isolation, separation, and characterization of different classes of phenolic compounds, ranging from phenols and phenolic acids to phenylpropanoids, lignins, stilbenes and phenanthrenes, flavones and flavonols, chalcones and aurones, flavanoids, anthocyanins, biflavanoids, tannins, isoflavanoids, quinones, xanthones, and lichen substances. The book is a valuable resource for students, biochemists, and researchers in the plant sciences.
In the second edition of this book, the origin, upkeep and latex harvest from the Hevea rubber tree are dealt with succinctly. New chapters have been included on Propagation Systems and Genetic Resources. The importance of Heterozygosis and Breeding is a new theme for the section on Breeding. A new chapter on Genomics and Molecular Breeding that focuses on the latest advancements on gene mapping, marker assisted selection and stimulation has been added. Lastly, ‘textboxes’ that highlight points and topics of significant interest are included in the new addition. Natural rubber has been an essential commodity not only for the tire industry but also for more than 50,000 products that holds elasticity as an attribute. The prime source of natural rubber worldwide is Hevea brasiliensis. Hevea rubber tree is an excellent example of how a soil-tree-atmosphere system can work in tandem. The retrieval of rubber through ‘injuring’ the tree on alternate days or once in three days or once in seven days, is indeed a unique arrangement followed universally that ensures income to the planter almost throughout the year. Every molecule of rubber is the end result of meticulous biochemical changes. Therefore the biology of Hevea rubber tree itself is a subject that aggregates science and technology for the realization of its industrial utility.
Editing a book of this nature was a simultaneously exhilarating and frightening experience. It was exhilarating to draw from cell biologists, biochemists, and molecular biologists, as well as those dermatologists, pathologists, and pul monologists who are cell biologists at heart, to author chapters. At the same time, it was frightening to ask such busy investigators to devote their precious time to writing chapters that summarize not just their own endeavors but their entire area of expertise. However, the authors assuaged our fears by enthusi astically accepting the proposal to write on specific topics despite the time burden, and to update and willingly accept our editorial comments. In the editors' view, the authors have captured the important scientific data in their respective fields, have organized the data into an understandable outline, and have applied the information to elucidating wound repair processes. The explosion of new, important discoveries in the field of wound repair and related areas as our book was developing has been very unsettling. This observation predicts obsolescence. In response to this possibility, the authors and the editors have attempted to build fundamental concepts upon existing data. Hopefully, these concepts will help provoke further experimentation to unravel the complex, interwoven processes of wound repair. The book has been organized into three parts: Inflammation, Granulation Tissue Formation, and Extracellular Matrix Production and Remodeling.
Climate change is a major challenge for life on Earth. It is mainly manifested through modifications of average temperature, rainfall intensity and patterns, winds and solar radiation. These modifications significantly affect basic resources, such as land and water resources. Populations at disproportionately higher risk of adverse consequences with global warming of 1.5°C and beyond include disadvantaged and vulnerable populations, some indigenous peoples, and local communities dependent on agricultural or coastal livelihoods (IPCC, 2018). Therefore, adaptation measures are recommended in order to cope with climate change. Indigenous peoples have developed practices for climate change adaptation, based on their long-term experience with adverse climatic effects. There was thus a need to identify such practices as they could be effectively mainstreamed in community-based adaptation programmes. This report makes an inventory of indigenous and community adaptation practices across the world. The inventory was mainly done through literature review, field work and meetings with selected organisations. The case studies documented are categorized in five technologies and practices themes, including: (1) Weather forecasting and early warning systems; (2) Grazing and Livestock management; (3) Soil and Water Management (including cross slope barriers); (4) Water harvesting (and storage practices); (5) Forest Management (as a coping strategy to water scarcity), and; (6) Integrated wetlands and fisheries management. These were then related to the corresponding main agro-ecological zones (AEZ), namely arid, semi-arid, sub-humid, humid, highlands and coastal and wetlands. The AEZ approach was considered as an entry-point to adopting or adapting an existing indigenous strategy to similar areas. Challenges that threaten the effectiveness of indigenous and community adaption strategies were identified. These challenges include climate change itself (which is affecting the indicators and resources used by communities), human and livestock population growth (which is increasing pressure on natural resources beyond their resilience thresholds), current institutional and political settings (which limit migrants’ movements and delimits pieces of usable land per household), cultural considerations of communities (such as taboos and spiritual beliefs), and the lack of knowledge transfer to younger communities. Indigenous knowledge provides a crucial foundation for community-based adaptation strategies that sustain the resilience of social-ecological systems at the interconnected local, regional and global scales. In spite of challenges and knowledge gaps, these strategies have the potential of being strengthened through the adoption and adaptation of introduced technology from other communities or modern science. Attention to these strategies is already being paid by several donor-funded organisations, although in an uncoordinated manner.
Addressing the intelligent concepts of the ancient endeavour of road design, this book discusses how a road alignment optimization model can be developed and applied in real case studies. Based on research in intelligent road design and alignment optimization, it is suitable for road planners, designers, senior undergraduate and graduate students.
The increasing population densities of Asia, Africa and Oceania are in conflict with the ecosystem. A growing demand for food and fiber causes agriculture to rely heavily upon chemical fertilization, herbicides and pesticides. Rising industrial output creates higher contamination from cadmium, lead, selenium, and other metals. Soils and Groundwater Remediation explores the toxic levels of metals, radionuclides, inorganics, and anthropogenic organic compounds found in the soils and groundwater of Asia, Africa and Oceania. This 14 chapter book reviews the distribution, transformation, and dynamics of the pollutants. The authors also reflect on the impact of Acid-rain. The contributors to this book are well-known scientists from Japan, China, Korea, Malaysia, New Zealand, Australia, and Kenya. The authors address their findings to researchers, educators, government regulators, and students. As the title suggests, the book is ultimately concerned with remediation. Huang and Iskandar feel "the potential for restoring ecosystem health ... in these areas is enormous." The contributions of Soils and Groundwater Remediation will bring science closer to achieving that possibility.
Aeronomy, Part B discusses the scientific discipline devoted to the study of the composition, movement, and thermal balance of planetary atmospheres. The book presents the comprehensive exposition of the basic processes involved in the aeronomy of the earth's upper atmosphere. It demonstrates the chemical, ionic reactions, and the different collisional interactions involving particles and radiation. The text describes the molecular diffusion and its effects in producing the transition from homogeneous molecular gases of lower atmosphere to the heterogeneous atomic and molecular gases of the upper atmosphere. It also discusses the simple models of the ionospheres. Another topic of interest is the calculations of atmospheric photoionization. The section that follows describes the satellite and external hyperbolic particles. The book will provide valuable insights for engineers, scientists, students, and researchers in the field of space science.

Breeding Major Food Staples covers improving yields and quality of these crops through breeding and the use of molecular biology tools such as gene transfer, genome mapping, biofortification, and bioinformatics. This book will be an important reference for anyone working in crop breeding.
Nanomaterials are defined as materials in which at least one length dimension is below 100 nanometers. In this size regime, these materials exhibit particular - and tunable - optical, electrical or mechanical properties that are not present at the macro-scale. This opens up the possibility for a plethora of applications at the interface of materials, chemistry, physics and biology, many of which have already entered the commercial realm. When nanomaterials are blended with other materials not necessarily in the nanometer regime, the resulting nanocomposites can exhibit dramatically different properties than the bulk material alone, leading to an enhanced performance in terms of, for example, increased thermal and mechanical stability. This book presents the synthesis, characterization and applications of nanomaterials and nanocomposites, covering zero-dimensional, elemental nanoparticles, one-dimensional materials such as nanorods and nanowhiskers, two-dimensional materials such as graphene and boron nitride as well as three-dimensional materials such as fullerenes, polyhedral oligomers and zeolites, complemented by bio-based nanomaterials, e.g., cellulose, chitin, starch and proteins. Introductory chapters on the state-of-the-art of nanomaterial research and the chemistry and physics in nanoscience and nanotechnology round off the book.

Aimed at students, faculty and professionals in the aerospace field, this book provides practical information on the development, analysis, and control of a single and/or multiple spacecraft in space. This book is divided into two major sections: single and multiple satellite motion. The first section analyses the orbital mechanics, orbital perturbations, and attitude dynamics of a single satellite around the Earth. Using the knowledge of a single satellite motion, the translation of a group of satellites called formation flying or constellation is explained. Formation flying has been one of the main research topics over the last few years and this book explains different control approaches to control the satellite attitude motion and/or to maintain the constellation together. The control schemes are explained in the discrete domain such that it can be easily implemented on the computer on board the satellite. The key objective of this book is to show the reader the practical and the implementation process in the discrete domain. - Explains the orbital motion and principal perturbations affecting the satellite - Uses the Ares V rocket as an example to explain the attitude motion of a space vehicle - Presents the practical approach for different control actuators that can be used in a satellite
Fjords are both an interface and a buffer between glaciated continents and the oceans. They exhibit a very wide range in environmental conditions, both in dynamics and geography. Some are truly wonders of the world with their dizzying mountain slopes rising sharply from the ocean edge. Others represent some of the harshest conditions on earth, with hurricane winds, extremes in temperature, and catastrophic earth and ice movements. Fjords are unique estuaries and represent a large portion of the earth's coastal zone. Yet they are not very well known, given the increasing population and food pressures, and their present industrial and strategic importance. Temperate zone estuaries have had many more years of intense study, with multiyear data available. Most fjords have not been impacted by man but, if history repeats itself, that condition will not last long. Fjords present some unique environmental problems, such as their usually slow flushing time, a feature common to many silled environments. Thus there is presently a need for management guidelines, which can only be based on a thorough knowledge of the way fjords work. Fjords are, in many respects, perfect natural oceanographic and geologic lab oratories. Source inputs are easily identified and their resulting gradients are well developed. Throughout this book, we emphasize the potential of modeling pro cesses in fjords, with comparisons to other estuary, lake, shelf and slope, and open ocean environments.
Trees in dryland forests and wooded areas provide key ecosystem services such as animal feed, timber, fruits and, regulation of soil and water cycles. Equally, the presence of livestock in dryland woody areas can also play an important role in the local ecosystem; not only are they a source of income for local communities, but they also help vegetation and mobilise stored biomass. When both of these ecosystem elements are wisely combined – livestock and trees – it creates an integrated agricultural system that can boost the local ecosystem, representing a welcome agro-ecological transition in livestock farming. The ‘Grazing with Trees’ report gives a thorough assessment of the positive role that optimized extensive grazing livestock farming can play in the management and restoration of drylands’ forests and lands with trees. It assesses and provides sound evidence on the benefits of applying an integrated landscape approach and utilizing farmers and pastoralists’ knowledge to halt desertification, increase resilience, and enhance food security under the actual changing scenario. The report confirms the importance of agroforestry as a primary pathway for forest restoration in dryland areas as recommended by FAO’s State of Forests 2022, and its recommendations encourage landscape planners and decision makers to consider livestock as allies, carefully restore tree cover and accelerate action to promote healthy ecosystems.

Latest figures suggest that approximately 20% of the world's population of six billion is malnourished because of food shortages and inadequate distrib ution systems. To make matters worse, it is estimated that some 75 billion metric tons of soil are removed annually from the land by wind and soil ero sion, much of it from agricultural land, which is thereby rendered unsuitable for agricultural purposes. Moreover, out of a total land area under cultivation 9 6 of approximately 1. 5 x 10 ha, some 12 x 10 ha of arable land are destroyed and abandoned worldwide each year because of unsustainable agricultural practices. Add to this the fact that the world population is increasing at the rate of a quarter of a million per day, and the enormity of the task ahead becomes apparent. To quote the eminent wheat breeder E. R. Sears, It seems clear that plant geneticists can look forward to an expanded role in the 21st century, particularly in relation to plant improvement. The suc cess of these efforts may go a long way towards determining whether the world's increasing billions of humans will be adequately fed. Food for an ever-increasing population will have to be produced not only from an ever-diminishing, but from what will become an ever-deteriorating land resource unless justifiable environmental concerns are taken into account.
For Students, Scholars, Researchers, Investigators, Trainees and Scientists. "If I have seen a little further it is by standing on the shoulders of Giants." Isaac Newton. This book on research is an attempt to try to answer the basic fundamental questions that come to the minds of young students, researchers, scholars, investigators, trainees or scientists. It is an outcome of collaboration between 43 researchers from 11 different countries (Pakistan, India, United States, Iran, United Kingdom, Nepal, Canada, Greece, Poland, Japan and Australia): Achakzai AM, Afghan AK, Ahmed A, Ali D, Ans M, Asad RM, Ashfaq A, Butt NM, Farooq F, Fatima M, Gilani AI, Ibrahim M, Ishtiaq O, Janjua NZ, Kakisi O, Kasi PM, Kassi M, Kassi M, Khan SF, Khawar T, Kiani J, Kulkarni HS, Majeed A, Naqvi HA, Nawaz H, Oberoi DV, Qureshi SA, Rai AS, Rathore FA, Rehman R, Sabri AA, Saeed F, Shah M, Shankar R, Sharma A, Sherjeel SA, Shoraneh F, Siddiqui S, Syed FK, Szlufic S, Yaqoob N, Zafar A, Zaidi AH Although there is a lot of literature available to answer the queries that come to the mind of a young investigator, the language is often too complex and difficult to understand and thus, aversive. Some of these teaching materials sound more like experts talking to each other. This book would act as a catalyst in providing useful reviews and guidance related to different aspects of research for students who need to be inducted and recognized as an integral part of the research community. We hope researchers benefit from this endeavor of ours. E-mail: pashtoon.kasi@gmail.com Website: www.PromotingResearch.com
