Chelyabinsk Superbolide
On February 15, 2013, the Chelyabinsk meteor sailed over Russian skies in a streak of light that was momentarily brighter than the Sun. The remarkable event and its subsequent shock wave were witnessed and documented by countless local residents, launching a widespread scientific expedition to gather and study the remaining meteoritic fragments. This book chronicles Chelyabinsk’s tale of recovery and discovery from the minds of many of the scientists who studied the superbolide, leading field experiments and collecting meteorites and meteorite dust across the region. The Chelyabinsk superbolide is a complex and multi-aspect phenomenon. The book not only presents the results of the scientific research but also details the firsthand experiences of those involved in such efforts, providing readers with a unique opportunity to look at the "inner workings" of science that are seldom shown to the public. Over the course of their studies, the scientists collected over 200 photographs and a dozen video recordings taken by nearly 40 different eyewitnesses. Many of those never-before-published illustrations and photos can be found in full color in the pages of this book.
Radioaktivität - Band II
Radioaktivität wird seit Jahrzehnten heiß debattiert; Nutzen und Gefahren der Kernenergie stehen dabei im Mittelpunkt. Das Thema greift jedoch weiter - sowohl in Bezug auf natürliche Vorkommen als auch vielfache Anwendungen von Radioaktivität. Nach summarischer Darstellung der Radioaktivität als natürlicher Erscheinung in Band I wendet sich der Autor in Band II der wachsende Anwendung und Bedeutung von Radioaktivität in der modernen industrialisierten Welt zu. Er beschreibt das Anwachsen der Belastung durch radioaktive Strahlung im menschlichen Umfeld wie auch durch die verschiedenen industriellen Anwendungsgebiete. Dazu zählen nicht nur Themen wie Kernwaffen und Kernenergie, sondern auch Nutzung radioaktiver Stoffe in Ackerbau, Industrie, Medizin und sogar Kunstgeschichte. Zahlreiche Beispiele verdeutlichen das. In diesem Rahmen werden auch die Möglichkeiten zur Endlagerung oder Entsorgung langlebiger radioaktiver Substanzen und die damit verbundenen technischen Probleme diskutiert.
Neutron Capture Therapy
Neutron capture therapy (NCT) is based on the ability of the non-radioactive isotope boron-10 to capture thermal neutrons with very high probability and immediately to release heavy particles with a path length of one cell diameter, which in principle allows for tumor cell-selective high-LET particle radiotherapy. This book provides a comprehensive summary of the progress made in NCT in recent years. Individual sections cover all important aspects, including neutron sources, boron chemistry, drugs for NCT, dosimetry, and radiation biology. The use of NCT in a variety of malignancies and also some non-malignant diseases is extensively discussed. NCT is clearly shown to be a promising modality at the threshold of wider clinical application. All of the chapters are written by experienced specialists in language that will be readily understood by all participating disciplines.
The Exploited Seas
The book combines the approaches of maritime history and ecological science to explore the evolution of life-forms and eco-systems in the ocean from a historical perspective, in order to establish and develop the sub-discipline of marine environmental history. Documentary records relating to the human activity, such as fishing, plus naturally occurring paleo-ecological data are analysed in order to determine the structure and function of exploited ecosystems. The book is divided into four chapter groups, the first concerned with Newfoundland and Grand Banks’ fisheries, the second with the potential of historical sources to provide a history of marine animal populations, the third explores the development of fisheries in the southern hemisphere during the twentieth century, and the final section explores the limitations of data and existing analysis of whale populations. The epilogue reiterates the suggestion that collaboration between historians and biologists is the key to furthering the sub-discipline.
Proceedings of the International Conference Industrial and Civil Construction 2021
This book gathers the latest advances, innovations, and applications in the field of construction design and management, as presented by researchers and engineers at the International Conference Industrial and Civil Construction 2021, held in Belgorod, Russia, on January 18-19, 2021. It covers highly diverse topics, including building materials, building constructions, structural mechanics and theory of structures, industrial and civil construction, environmental engineering and sustainability. The contributions, which were selected by means of a rigorous international peer-review process, highlight numerous exciting ideas that will spur novel research directions and foster multidisciplinary collaborations.
Multiple Stressors: A Challenge for the Future
Ecotoxiclogical risk from multiple stressors covers any situation where org- isms are exposed to a combination of environmental stressors. These include physical and chemical pollutants as well as other stressors such as parasites and environmental impact (e. g. , climate change or habitat loss). The combi- tion of stressors can result in increased risk to organisms (either additive or synergistic effects) or decreased effects (protective or antagonistic effects). The multiple stressor challenge is an international, multi-disciplinary problem requiring an international, multi-disciplinary approach. The c- rent approach to multiple stressors is to examine one stressor at a time and assume add...
