Hardback. Condizione: New. Despite decades of study, fundamental aspects of the development of the Earth's crust remain enigmatic. This book presents geophysical and geological studies obtained from different tectonic structures and geological time intervals. It contains three sections: "Crustal Evolution and Tectonic Problems", "Geophysical Methods in Geological Applications" and "Seismic Forecasting, Seismotectonics and Geodynamic Evolution of the Himalayan Belt". Chapters address such topics as the evolution of tectonic structures of Earth, how geophysical and geological data can be used for modelling this evolution, and the geodynamic processes in the Earth's crust with the present tectonic activity.…

Soil Science - Emerging Technologies, Global Perspectives and Applications describes recent research that illustrates the universal importance of understanding soil and soil's relationship to environmental stewardship and food security. Research supporting emerging technologies provides abilities to discern key soil attributes that influence soil behavior and development, understand soil biology to create sustainable land management, and sequester carbon to partially negate climate change. Soil science is an interdisciplinary field of inquiry that must consider resource allocation and social needs to foster a culture that protects and secures not only soil health but also water and air quality. Chapters in this book reflect the diversity of modern thinking within the discipline of soil science, but collectively illustrate that global sustainability of food, the environment, and biological diversity are critical to future generations.…

Hardback. Condizione: New. Epigenetics, which deals with the study of heritable gene expression that takes place independent of changes in DNA sequence, and optogenetics, which deals with the study of genes expressed under the influence of light, are two emerging areas of study and research that have contributed immensely to our current knowledge of mechanisms and disease processes in humans. These disciplines are interrelated in the broader picture of biology and one can be used to change or modify the other. The complexity of the techniques involved in these disciplines often leads to a lack of proper understanding by researchers from other disciplines and the scientific community at large. As such, this book provides simple and easy-to-follow explanations of some of the most exciting areas of research in these disciplines.…

Hardback. Condizione: New. Worldwide interest in nuclear reactors continues to increase and significant focus has been placed on advanced nuclear reactors intended to produce electricity and process heat. However, there is limited literature on the importance of research reactors and certain specialized reactor analysis topics. Thus, this book addresses these topics over three sections: "Nuclear Reactors for Spacecraft Propulsion", "Research Reactors", and "Select Reactor Analysis Techniques". It provides detailed information on the use of nuclear reactors for spacecraft propulsion, presents research conducted on reactors in Idaho, USA, and discusses reactor analysis topics such as cyber-informed engineering for nuclear reactor digital instrumentation and control, the effect of plenum gas on fuel temperature, and more.…

Hardback. Condizione: New. Keratinocytes have various functions to maintain epidermal homeostasis. Many inflammatory skin diseases can develop due to suppressed or defective anti-inflammatory properties of keratinocytes. This book discusses the structural, biological, and molecular aspects of keratinocytes. Chapters discuss keratins and attachment molecules and their importance in maintaining epidermal homeostasis, skin diseases such as psoriasis and atopic dermatitis, and aging and skin regeneration.…

Staphylococcus spp. and Streptococcus spp. that are Gram positive cocci are the main pathogens in several infections. Virulence factors such as usual and unusual surface proteins encoded by resistance genes are the main causes of pathogenesis. Multidrug-resistant pathogens that are the main causes of morbidity and mortality worldwide have the ability to synthesize a number of destructive enzymes encoded by resistance genes such as ?-lactamases. Resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pneumoniae, Group A, and Group B Streptococcus have emerged throughout the world. To eliminate these resistant pathogens that cause untreatable, acute, and chronic infections, different new antimicrobials must be developed and used. The goal of this book is to provide the latest information about the above topics.…

Hardback. Condizione: New. Bacteriophages are viruses that utilise bacterial cells as factories for their own propagation and as safe havens for their genomic material. They are capable of equipping bacteria with properties that bestow environmental advantages. They are also capable of specifically and efficiently killing bacteria.Bacteriophages are resilient in a wide diversity of environments, presumed to be as ancient as life itself, and are estimated to be the most numerous biological entities on the planet. Their overarching capacity to survive via molecular adaptation is supported by an arsenal of encoded enzymatic tools, which also enabled biotechnology. This volume includes contributions that describe bacteriophages as nanomachines, genetic engineers, and also as medicines and technologies of the future, including relevant production and process issues.…

Organic crop production is the science and art of growing field crops, fruits, vegetables, and flowers by adopting the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety conservation. This book provides detailed insights into organic farming in agriculture, biological efficacy in the management of plant diseases, organic nutrient management, socio-economic dimensions of adoption of conservation practices, nonchemical weed control, plant growth promoting fungi for phytostimulation, nanotechnological approaches, and finally vermicomposting. The book primarily focuses on research and development based organic agriculture and horticulture production technologies, and has attempted to abridge information on organic crop production of the major food grain crops. The book also contains comprehensive information on the various related dimensions of organic crop production.…

While initially associated with patients with advanced co-morbidities, such as renal failure and chronic immunosuppression, endocarditis now spans many diverse disciplines. As such, the importance of advanced diagnostic imagining tools, a better understanding of the pathophysiology of not only the infectious (and non-infectious) disease process but also of cardiac structural abnormalities, and the growing literature on management cannot be underemphasized. This book broadens our collective understanding of the spectrum of diagnostic and therapeutic challenges that all areas of medicine must appreciate when faced with the challenging clinical problem of endocarditis.…

Hardback. Condizione: New. Endocarditis is a disease process that involves an infection of the heart, cardiac structures, or implantable cardiac support devices and can be a difficult clinical problem. As patients get older and have more comorbidities, their risks for infection increase. In addition, the growing problem of intravenous substance abuse has led to a considerable increase in these patients developing endocarditis. Advances in medical technology have facilitated diagnosis and management, particularly with greater emphasis on early surgical intervention. Nevertheless, success requires a team approach and individualization of care in the setting of very complex medical, surgical, and ethical problems. The goal of this book is to illustrate some of the evolving challenges and controversies in managing these very complex and often extremely sick patients.…
