Submerged Rice: Morphological, Molecular and Genetic Analyses

by Pranab Basuchaudhuri

Water stagnation and submergence are major factors in rice growing. Water stagnation and submergence happen as a result of excessive rainfall or flash floods. The duration of submergence can last several weeks, and the level of water may be as high as 100 cm. This impacts rice yields. This book analyzes different aspects, viz., morphology, physiology, biochemistry and genetics, and reviews the suitability of different varieties for better sustainability and reduction of yield loss. It also reviews the different types of floods, and studies biological changes in indigenous and recently developed rice varieties. There are seven chapters: Introduction, History of floods, Diversity of submergence, Adoptive morphology, Physiological aspects, Molecular and genetic aspects, and Yield and yield-gaps. It is comprehensive with scientific dogma, findings and reasonings for students at universities and researchers.

Suborbital

by Erik Seedhouse

The nascent commercial suborbital spaceflight industry will soon open the space frontier to commercial astronauts, payload specialists, scientists and of course, tourists. This book describes the tantalizing science opportunities to be offered when suborbital trips become routine within the next 12 to 18 months. It describes the difference in training and qualification necessary to become either a spaceflight participant or a fully-fledged commercial suborbital astronaut and it describes the vehicles this new class of astronauts will use. Anticipation is on the rise for the new crop of commercial suborbital spaceships that will serve the scientific and educational market. These reusable rocket-propelled vehicles are expected to offer quick, routine and affordable access to the edge of space along with the capability to carry research and educational crew members. Yet to be demonstrated is the hoped-for flight rates of suborbital vehicles. Quick turnaround of these craft is central to realizing the profit-making potential of repeated sojourns to suborbital heights. As this book outlines, vehicle builders still face rigorous shake-out schedules, flight safety hurdles as well as extensive trial-runs of their respective craft before suborbital space jaunts become commonplace. The book examines some of these 'cash and carry' suborbital craft under development by such groups as Blue Origin, Masten Space Systems, Virgin Galactic and XCOR Aerospace and describes the hurdles the space industry is quickly overcoming en-route to the industry developing into a profitable economic entity. Seedhouse also explains how the commercial suborbital spaceflight industry is planning and preparing for the challenges of marketing and financing and how it is marketing the hiring of astronauts. It examines the role of commercial operators as enablers accessing the suborbital frontier and how a partnership with governments and the private sector will eventually permanently integrate the free market's innovation of commercial suborbital space activities.

Subsidence Analysis and Visualization: For Sedimentary Basin Analysis and Modelling (SpringerBriefs in Petroleum Geoscience & Engineering)

by Eun Young Lee Johannes Novotny Michael Wagreich

This book provides a comprehensive introduction to techniques for quantitative subsidence analysis and visualization with example applications. Subsidence analysis is an essential step to understand basin evolution through geologic time and space in the study of sediments and sedimentary basins. Quantifying techniques have been developed and applied in many basin research projects to evaluate total, tectonic and thermal subsidence. They are also a pre-requisite for basin evolution modelling. Recent studies have applied visualization techniques to understand regional subsidence contexts and trends, which confirmed that three-dimensional visualization of the basin subsidence is highly helpful to gain insight into basin evolution. In this book, we show how geoscience and computer science can be effectively combined in advanced basin analysis, especially in terms of basin subsidence. Each type of subsidence analysis is introduced with example applications. In particular we present a study of the Vienna basin using BasinVis, a MATLAB-based program for analyzing and visualizing basin subsidence. Given its breadth of coverage, this book will benefit students in undergraduate and postgraduate courses and provide helpful information for research projects and industry applications.

Subsoil Constraints for Crop Production

by Teogenes Senna de Oliveira Richard Willian Bell

This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

Substrate Analysis for Effective Biofuels Production (Clean Energy Production Technologies)

by P. K. Mishra Vijai Kumar Gupta Neha Srivastava Manish Srivastava

As a substrate, cellulose plays a crucial role in the biomass-based biofuel production process, and is essential to enzyme and sugar production. Accordingly, ensuring maximum availability of cellulose for enzyme production and bioconversion for sugar generation is one of the major challenges for sustainable biofuels production. To date there has been extensive research on biofuel production using lignocellulosic biomass, but there is a huge gap when it comes to the critical analysis of cellulose content, structural feasibility, availability, and economic processing, so that it can be converted for enzyme and fuel production at low cost.Consequently, this book discusses the availability of lignocellulosic substrate for biofuel production in light of the challenges that the biofuels industry is currently facing. After identifying the major substrate selection challenges for the practical biofuel production process, the book addresses said challenges by focusing on various issues such as: potential substrates that have high cellulosic content, structural feasibility, and low-cost & effective processing to remedy the structural complexity of biomass structure and create added value. In addition, it covers recent advancements in cellulase production and outlines future prospects.Given its scope, it offers a valuable guide for research students and industry practitioners alike.

Subsurface Solute Transport Models and Case Histories

by Vyacheslav G. Rumynin

The book addresses the development of the basic knowledge of the subsurface solute transfer with a particular emphasis on field data collection and analysis coupled with modeling (analytical and numerical) tool application. The relevant theoretical developments are concerned mainly with the formulation and solution of deterministic mass-transport equations for a wide range of engineering issues in groundwater quality assessment and forecasting. The book gives many computational examples and case studies drawn from the conducted field investigations. The analyzed problems are as follows: investigation and prediction of groundwater contamination by industrial contaminants and solutions (radionuclides, chloride and nitrate brine) with special focus on the effect of (a) aquifer heterogeneity, anisotropy, and dual porosity, (b) density contrast existing between industrial waste and groundwater, or in density-stratified artesian and coastal groundwater systems; (c) physicochemical interactions that play a major role in retarding (e.g. adsorption) or enhancing (e.g. interactions between dissolved species and mobile colloids) contaminant transport;prediction of the effects of pumping on groundwater quality at wellfields;groundwater dating using stable and radioactive isotopes for prediction and assessment of contamination potential;field and laboratory tests' design and analysis, and monitoring data interpretation;partitioning of surface and subsurface flows using isotope techniques.One of the most essential topics addressed in the book is the migration and fate of radionuclides. Model development is motivated by field data analysis from a number of radioactively contaminated sites in the Russian Federation: near-surface radioactive waste disposal sites and deep-well radioactive waste injection sites. They play a unique role in the advancement of knowledge of the subsurface behavior and fate of many hazardous radionuclides and can be considered as field-scale laboratories. Thus, the book, along with theoretical findings, contains field information, which will facilitate the understanding of subsurface solute transport and the development of a methodology for practical applications to groundwater hydrology.

Subsurface Upgrading of Heavy Crude Oils and Bitumen

by Cesar Ovalles

Heavy crude oils and bitumen represent more than 50% of all hydrocarbons available on the planet. These feedstocks have a low amount of distillable material and high level of contaminants that makes their production, transportation, and refining difficult and costly by conventional technologies. Subsurface upgrading of heavy crude oils and bitumen is of interest to the petroleum industry mainly because of the advantages compared to aboveground counterparts. This book presents an “in depth” account and a critical review of the progress of industry and academia in the area of subsurface upgrading of heavy, extra-heavy oils and bitumen, as reported in the patent and open literature.

Subtelomeres

by Edward J. Louis Marion M. Becker

New genes and diversity leading to adaptation and evolution are generated in special areas of genomes. One such area in all eukaryotic genomes and in those prokaryotes with linear chromosomes is the region near the ends of the chromosomes. These telomere-associated sequences or subtelomeres, have different properties than the rest of the genome and are one of the most exciting frontiers left in genomics. This book provides a broad introduction to the field of subtelomeres with detailed information from various fields and systems, covering yeasts and fungi, pathogens and parasites, plants, insects, humans and primates and bacteria with linear chromosomes. Advances in the field as well as continuing challenges are discussed throughout. The mosaic nature of this collection and the everchanging perspectives reflect the nature of subtelomeres themselves. Unlike the core of most genomes, which are conserved and stable over time, subtelomeres are dynamic and polymorphic, so much so that generally no two individuals look alike in these regions. The dynamic nature of the region and the ability to change the copy number, generate diversity and try novel combinations make it the evolutionary tinker's toolbox. In many organisms the genes found in the region are involved in dealing with the environment. In yeasts, different gene families involved in sugar metabolism as well as clumping together are found in subtelomeres and differences in the region may be the reason why some strains are good for baking, others for brewing and why some are pathogenic. In fungal plant and animal pathogens, many of the genes involved in virulence are found here. In humans and primates there are a number of gene families that vary between ends, for example the diverse olfactory receptor genes. Even in bacterial linear chromosomes the region contains genes involved in adapting to their environments. Perhaps the ultimate use of these regions is in parasites where they rapidly adapt and escape from host immune systems through dynamic changes to the proteins exposed to the host's defenses. Such dynamic, polymorphic structures are also found in plants and insects though it is not always clear what the function might be; in some cases they take on the role of end maintenance. The dynamic, polymorphic nature of subtelomeres, where many ends share segmental duplications, is an exciting area for study but also presents a difficult challenge from the technical perspective.

Subtle Agroecologies: Farming With the Hidden Half of Nature (Advances in Agroecology)

by Julia Wright Nicholas Parrott

This book is about the invisible or subtle nature of food and farming, and also about the nature of existence. Everything that we know (and do not know) about the physical world has a subtle counterpart which has been scarcely considered in modernist farming practice and research. If you think this book isn’t for you, if it appears more important to attend to the pressing physical challenges the world is facing before having the luxury of turning to such subtleties, then think again. For it could be precisely this worldview – the one prioritises the physical-material dimension of reality - that helped get us into this situation in the first place. Perhaps we need a different worldview to get us out? This book makes a foundational contribution to the discipline of Subtle Agroecologies, a nexus of indigenous epistemologies, multidisciplinary advances in wave-based and ethereal studies, and the science of sustainable agriculture. Not a farming system in itself, Subtle Agroecologies superimposes a non-material dimension upon existing, materially-based agroecological farming systems. Bringing together 43 authors from 12 countries and five continents, from the natural and social sciences as well as the arts and humanities, this multi-contributed book introduces the discipline, explaining its relevance and potential contribution to the field of Agroecology. Research into Subtle Agroecologies may be described as the systematic study of the nature of the invisible world as it relates to the practice of agriculture, and to do this through adapting and innovating with research methods, in particular with those of a more embodied nature, with the overall purpose of bringing and maintaining balance and harmony. Such research is an open-minded inquiry, its grounding being the lived experiences of humans working on, and with, the land over several thousand years to the present. By reclaiming and reinterpreting the perennial relationship between humans and nature, the implications would revolutionise agriculture, heralding a new wave of more sustainable farming techniques, changing our whole relationship with nature to one of real collaboration rather than control, and ultimately transforming ourselves.

A Subtle Balance: Expertise, Evidence, and Democracy in Public Policy Governance, 1970-2010

by Edward A. Parson

From the Asian tsunami of 2004 to hurricane Katrina in 2005 and the Tohoku earthquake of 2011, our century has been fraught with catastrophic natural disasters. Disaster Risk and Vulnerability assesses the human toll and economic losses of natural disasters and reasserts the importance of human collaboration and organization in disaster management. In most cases, policy makers, planners, managers, and regulators who implement disaster risk reduction response planning and management strategies remain detached from local conditions, failing to address them effectively. Presenting case studies from Asia and North America, as well as a broad range of approaches to community mobilization and partnership development, contributors show that local communities, all levels of government, and non-governmental organizations must work collectively in order to reduce the harm caused by disasters. Despite unprecedented progress in science and technology and governments' continued efforts in disaster risk reduction, socioeconomic losses due to environmental disasters continue to rise. Disaster Risk and Vulnerability provides knowledge and information that will benefit anyone working in the fields of environment, disasters, and community mobilization in an effort to reverse this trend.

Subtract: The Untapped Science of Less

by Leidy Klotz

Blending evidence across science and design, Subtract: The Untapped Science of Less offers a revolution in problem-solving: proving why we overlook subtraction, and how we can access its true potentialWe pile on “to-dos” but don’t consider “stop-doings.” We create incentives for good behavior, but don’t get rid of obstacles to it. We collect new-and-improved ideas, but don’t prune the outdated ones. Every day, across challenges big and small, we neglect a basic way to make things better: we don’t subtract.Leidy Klotz’s pioneering research shows why. Whether we’re building Lego models or cities, grilled-cheese sandwiches or strategic plans, our minds tend to add before taking away. Even when we do think of it, subtraction can be harder to pull off because an array of biological, cultural, and economic forces push us towards more. But we have a choice—our blind spot need not go on taking its toll on our cities, our institutions, and our minds. By diagnosing our neglect of subtraction, we can treat it. Subtract will change how you change your world. In these pages you’ll meet subtracting exemplars: design geniuses, Nobel Prize-winners, rock-stars, and everyday heroes, who have subtracted to dismantle racism, advance knowledge, heal the planet, and even tell better jokes. These and more guiding lights show how we can revolutionize not just our day-to-day lives, but our collective legacy. A paradigm shift of a book, Subtract shows us how to find more of the options we’ve been missing—and empowers us to pursue them.

Subtropical Mountain Forests of Las Yungas: Vegetation and Bioclimate (Geobotany Studies)

by Gabriela S. Entrocassi Rosario G. Gavilán Daniel Sánchez-Mata

The vegetation addressed in this book is, biologically, one of the most diverse on Earth, with many characteristic taxa offering refuge and food sources for many resident and migratory animals. Yet the forests of Las Yungas remain poorly known from a floristic and vegetation point of view. This book seeks to fill that gap by studying the distribution of forest along an altitudinal but also a bioclimatic gradient. The richness in species demonstrates that these forests are substantially more diverse than other subtropical mountain woodlands. 103 diagnostic (characteristic or indicator) species were selected, of which 29 are dominant, 67 are exclusive, selective, preferential or differential, and 7 are stenoic. In addition, 13 communities were identified and characterized. These forests can be attributed to the Bolivian-Tucuman biogeographical province (South-Andean Region, Neotropical Sub-Kingdom). They are seasonal, semi-deciduous or evergreen micro- and mesowoodlands growing on foothills, hillsides, ravines, gorges and the edges of mountain ranges (terrestrial communities), as well as river terraces and beaches (riparian communities). Thanks to the range of new findings, the content presented here will benefit experts in related fields such as geographers, ecologists and botanists, but also teachers, nature guides, those involved in the management of forest or conservation areas, and policymakers.

The Suburban Apartment Boom: Case Study of a Land Use Problem (Routledge Revivals)

by Max Neutze

With an increase in urban crises arising from a growing population and rising affluence, and the inadequacy of conventional theories to predict the future states of the environment, Resources for the Future laid out a series of studies on the resource base of the urban environment. Originally published in 1968, this particular study examines the increase of apartment construction in the suburb including the extent of construction and the factors behind construction such as population demographics, highway construction and national and local land use policy. Neutze makes comparisons of U.S. metropolitan areas to draw conclusions on new policies which the government should consider in relation to the urban land market. This title will be of interest to students of Environmental Studies.
