Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

Download or read book Biological Electron Transfer Chains Genetics Composition and Mode of Operation written by G.W. Canters and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: From May 3-7,1997, the NATO Advanced Research Workshop on 'Biological Electron Transfer Chains' was organized in Tomar, Portugal. In the application for support the choice of the topic was justified as follows: "[Until recently efforts] have concentrated on the study of the structure and function of individual redox enzymes and proteins. Enough information is now available to make a start with the study of biological electron transfer (E1) at the next higher level of organization, that of the complete ET chain." The interest in the workshop was high: the majority of participants had registered before the workshop was formally announced, which illustrates the popularity of the topic within the biochemical and biophysical communities. The present volume contains a number of reports based on the lectures presented by the key speakers during the meeting. The workshop dealt with the following three themes: a) Electron transfer, which is the subject of Chapter 1. The analysis of ET at the molecular level is still fundamental for an understanding of how ET chains operate in vivo. After 40 years of research the contours of the subject are becoming clear now. b) Bacterial redox chains. This is the subject of Chapter 2. Its contents show how complicated these chains can be, often involving a number of gene clusters. Our understanding of the regulatory aspects and control mechanisms of these chains is only in its beginning.

This book was released on 2015-07-15 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past half-century has witnessed a dramatic increase in the scale and complexity of scientific research. The growing scale of science has been accompanied by a shift toward collaborative research, referred to as "team science." Scientific research is increasingly conducted by small teams and larger groups rather than individual investigators, but the challenges of collaboration can slow these teams' progress in achieving their scientific goals. How does a team-based approach work, and how can universities and research institutions support teams? Enhancing the Effectiveness of Team Science synthesizes and integrates the available research to provide guidance on assembling the science team; leadership, education and professional development for science teams and groups. It also examines institutional and organizational structures and policies to support science teams and identifies areas where further research is needed to help science teams and groups achieve their scientific and translational goals. This report offers major public policy recommendations for science research agencies and policymakers, as well as recommendations for individual scientists, disciplinary associations, and research universities. Enhancing the Effectiveness of Team Science will be of interest to university research administrators, team science leaders, science faculty, and graduate and postdoctoral students.

Download or read book Multi copper Oxidases written by Albrecht Messerschmidt and published by World Scientific. This book was released on 1997 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological activation of dioxygen is a key reaction in biological systems. Enzymes involved in direct oxygen activation are oxidases and oxygenases. Multi-copper oxidases are an important class of oxidases reducing dioxygen in a four-electron reduction to water with concomitant one-electron oxidation of the reducing substrate. The progress in the characterization and understanding of the structure and function of these enzymes has advanced so tremendously over the last ten years that the publication of a book documenting these achievements has been overdue.Especially the recent discovery of a key role of the FET3 protein of Saccharomyces cerevisae, a multi-copper oxidase, in iron metabolism of this eukaryote has underpinned the function of the plasma multi-copper oxidase ceruloplasmin in vetebrate iron transport. The lately determined x-ray structure of human ceruloplasmin confirms its close structural relatedness to the plant multi-copper oxidases ascorbate oxidase and laccase and due to strong amino-acid sequence similarities has allowed to construct a useful model of the more distantly related blood-clotting factor VIII.This book contains review articles from experts in the field, dealing with modern spectroscopy, enzyme kinetics, bioinorganic chemistry, x-ray crystallography, electron transfer reactions, molecular biology, medical aspects and potential industrial applications of the three main members of multi-copper oxidases, i.e., laccase, ascorbate oxidase and ceruloplasmin.

Download or read book Human Motion Sensing and Recognition written by Honghai Liu and published by Springer. This book was released on 2017-05-11 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the latest exciting advances in human motion sensing and recognition, from the theoretical development of fuzzy approaches to their applications. The topics covered include human motion recognition in 2D and 3D, hand motion analysis with contact sensors, and vision-based view-invariant motion recognition, especially from the perspective of Fuzzy Qualitative techniques. With the rapid development of technologies in microelectronics, computers, networks, and robotics over the last decade, increasing attention has been focused on human motion sensing and recognition in many emerging and active disciplines where human motions need to be automatically tracked, analyzed or understood, such as smart surveillance, intelligent human-computer interaction, robot motion learning, and interactive gaming. Current challenges mainly stem from the dynamic environment, data multi-modality, uncertain sensory information, and real-time issues. These techniques are shown to effectively address the above challenges by bridging the gap between symbolic cognitive functions and numerical sensing & control tasks in intelligent systems. The book not only serves as a valuable reference source for researchers and professionals in the fields of computer vision and robotics, but will also benefit practitioners and graduates/postgraduates seeking advanced information on fuzzy techniques and their applications in motion analysis.

Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Social Status Correlates summarizes findings from nearly 4000 studies on traits associated with variations in socioeconomic status. Much of the information is presented in roughly 300 tables, each one providing a visual snapshot of what research has indicated regarding how a specific human trait appears to be correlated with socioeconomic status. The social status measures utilized and the countries in which each study was conducted are also identified.QUESTIONS ADDRESSED INCLUDE THE FOLOWING: - Are personality traits such as extraversion, competitiveness, and risk-taking associated with social status? - How universal are sex differences in income and other forms of social status? - What is the association between health and social status? - How much does the answer vary according to specific diseases? - How well established are the relationships between intelligence and social status? - Is religiosity associated with social status, or does the answer depend on which religion is being considered? - Are physiological factors correlated with social status, even factors involving the brain? - Finally, are there as yet any "universal correlates of social status"?

Download or read book Hematopoiesis written by Leonard I. Zon and published by Oxford University Press. This book was released on 2001-04-12 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hematopoiesis, or the process of blood formation, has been extensively studied at both basic and clinical levels. Human diseases such as thalassemia, immunodeficiency, and leukemia represent defects in this process. Approaches to treat these disorders have required a basic understanding of the biology of blood cells. For instance, hemapoietic stem cell replacement or bone marrow transplantation has been used to ameliorate disease. This volume focuses on hematopoiesis at a cellular and molecular level, and establishes the basis for clinical manipulation of hematopoietic cells for therapeutic benefit. In Part I, the cellular characteristics of progenitors and stem cells are explored. Emphasis is placed on purification of stem cells and both in vitro and in vivo assays. The regulation of normal and leukemis stem cells is illustrated. An excellent discussion of potential use of these cells for gene therapy concludes this section. Hemapoiesis is easily studied during embryogenesis. Part II develops the concept of the waves of hemapoiesis during development. Comparative hematology is making a major comeback as a field in the 1990's. One hope is that general principles of hematopoiesis will be established by studying many models and systems. Part III delves into critical factors that regulate hematopoiesis, including both intracellular and extracellular signals. Part IV and V describe lineage programs for myeloid and lymphoid lineages. These chapters are meant to be illustrative of the different cell fates, but are not exhaustive. Part VI examines the genetics of hematopoisis, particularly in animal models. The hematopoietic system is in constant contact with stromal cells and endothelial cells during development and in the adult. Evidence suggests that endothelial cells and blood cells may arise from a common progenitor, the hemangioblast. Part VII and VIII discuss the stromal and endothelial cells with the emphasis on their interaction with hematopoietic cells.

Download or read book Lyme Disease Recent Advances and Perspectives written by Tanja Petnicki-Ocwieja and published by Frontiers Media SA. This book was released on 2015-08-08 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interplay between host and pathogen is a complex co-evolutionary battle of surveillance and evasion. The pathogen continuously develops mechanisms to subvert the immune response in order to establish infection while the immune system responds with novel mechanisms of detection. Because the majority of Lyme disease pathology is due to an over-exuberant immune response, much research in Borrelia burgdorferi pathogenesis has been devoted to understanding the mammalian host response to the bacterium. Immunological studies continue to be an active area of research employing emerging techniques, such as intra-vital imaging. These studies have furthered our understanding of inflammatory processes during long-term infection and provided some surprising insights, such as the continued presence of bacterial products after clearance. The field of Lyme disease has long debated the etiology of long-term inflammation and recent studies in the murine host have shed light on relevant cell types and inflammatory mediators that participate in the pathology of Lyme arthritis. Live imaging and bioluminescent studies have allowed for a novel view of the bacterial life cycle, including the tick mid-gut, tick-to-mammal transmission and dissemination throughout a mouse. A number of tick and bacterial proteins have been shown to participate in the completion of the enzootic cycle. Novel mechanisms of gene regulation are continuously being identified. However, B. burgdorferi lacks many traditional virulence factors, such as toxins or specialized secretion systems. Many genes in the B. burgdorferi genome have no known homolog in other bacteria. Therefore, studies focusing on host-pathogen interactions have therefore been limited by an incomplete understanding of the repertoire of bacterial virulence factors. Questions such as how the pathogen causes disease, colonizes the tick and evades host immune-surveillance have been difficult to address. Genetic studies involving single gene deletions have identified a number of important bacterial proteins, but a large-scale genomics approach to identify virulence factors has not been attempted until recently. The generation of a site-directed mutagenesis library is an important step towards a detailed analysis of the B. burgdorferi genome and pathogenome. Using this library, high-throughput genomic studies, utilizing techniques such as massively parallel sequencing have been promising and could be used to identify novel virulence determinants of disease in the mammalian host or persistence in the tick vector. Continued research on this unique pathogen and its specific interaction with host and vector may have far reaching consequences and provide insights for diverse disciplines including ecology, infectious disease, and immunology. Here, several reviews will discuss the most recent advances and future studies to be undertaken in the field of B. burgdorferi biology.

Download or read book Ecology of Amphibian Microbial Symbioses written by Eria A. Rebollar and published by Frontiers Media SA. This book was released on 2019-08-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of amphibian microbial ecology has greatly advanced in recent years. The work published to date has shown that amphibian skin bacterial communities can be influenced by host species, host life-history stage, environmental conditions, surrounding bacterial communities that serve as reservoirs and external biotic agents such as pathogens. As the ecology of amphibian-microbial symbiosis is a relatively new field, there are still many unanswered questions. The aim of this Research Topic is to highlight recent research on amphibian microbiomes that addresses relevant questions on the ecology of amphibian-microbe interactions. The publications gathered in this Research Topic have expanded our knowledge on the role of microbial symbionts of amphibians and have revealed novel insights that can direct the next set of research questions. We suggest that soon the field will move from the basic (and necessary) descriptions of microbial communities to more experimental approaches that include the use of omics methods and a variety of novel analytic and multivariate approaches. In addition to providing more insights into the microbial and disease ecology of amphibians, these studies may lead to effective ways to manipulate the microbiome to achieve protection from diseases, such as chytridiomycosis.
