Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of this work has been to examine the design of a delimiter for an Accelerator Based Neutron Source (ABNS) for Boron Neutron Capture Therapy (BNCT). The purpose of the delimiter is to shape the neutron field within a patients head in order to spare healthy tissue while delivering radiation to tumor cells and to simultaneously provide some degree of shielding to the patients body in order to reduce whole body exposure during treatment. In this evaluation, three previously developed assessment tools for delimiter performance have been combined to provide a more complete picture of the function of the delimiter in performing its dual roles. The first assessment tools that was used was the objective function (F) which provides a score based on the competing goals of sparing normal tissue and delivering high dose to tumor cells. The goal of the delimiter design is to achieve the highest F-score within an acceptable treatment time. The second assessment tool that was used was the beam assessment parameters of tumor dose and treatment time, where the goal is to achieve the highest possible tumor dose within an acceptable treatment time. The third assessment tool that was used was the whole body absorbed dose to the red bone marrow which measures the degree of shielding that the delimiter provides to the whole body of the patient. Here the goal of the design was to limit the whole body absorbed dose to the red bone marrow to values below the non-stochastic annual dose limit for radiation workers. Two parameters of delimiter design have been examined. The first parameter is the diameter of the treatment port and the second parameter is the axial thickness of the delimiter. As a basis for comparison, an Idealized Neutron Source with a 1/E energy spectrum was evaluated. For the Idealized Neutron Source the best beam diameter, of those evaluated, was found to be 15cm. For the delimiter the best configuration, of those evaluated, turned out to be a 15cm treatment port with an axial thickness of 13cm.

Download or read book Building Industries at Sea Blue Growth and the New Maritime Economy written by Kate Johnson and published by CRC Press. This book was released on 2022-09-01 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world there is evidence of mounting interest in marine resources and new maritime industries to create jobs, economic growth and to help in the provision of energy and food security. Expanding populations, insecurity of traditional sources of supply and the effects of climate change add urgency to a perceived need to address and overcome the serious challenges of working in the maritime environment. Four promising areas of activity for ‘Blue Growth’ have been identified at European Union policy level including Aquaculture; Renewable Energy (offshore wind, wave and tide); Seabed Mining; and Blue Biotechnology. Work has started to raise the technological and investment readiness levels (TRLs and IRLs) of these prospective industries drawing on the experience of established maritime industries such as Offshore Oil and Gas; Shipping; Fisheries and Tourism. An accord has to be struck between policy makers and regulators on the one hand, anxious to direct research and business incentives in effective and efficient directions, and developers, investors and businesses on the other, anxious to reduce the risks of such potentially profitable but innovative investments.The EU H2020 MARIBE (Marine Investment for the Blue Economy) funded project was designed to identify the key technical and non-technical challenges facing maritime industries and to place them into the social and economic context of the coastal and ocean economy. MARIBE went on to examine with companies, real projects for the combination of marine industry sectors into multi-use platforms (MUPs). The purpose of this book is to publish the detailed analysis of each prospective and established maritime business sector. Sector experts working to a common template explain what these industries are, how they work, their prospects to create wealth and employment, and where they currently stand in terms of innovation, trends and their lifecycle. The book goes on to describe progress with the changing regulatory and planning regimes in the European Sea Basins including the Caribbean where there are significant European interests. The book includes:• Experienced chapter authors from a truly multidisciplinary team of sector specialisms• First extensive study to compare and contrast traditional Blue Economy with Blue Growth• Complementary to EU and National policies for multi-use of maritime space

Download or read book Boron And Gadolinium Neutron Capture Therapy For Cancer Treatment written by Narayan S Hosmane and published by World Scientific. This book was released on 2012-03-07 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on two concurrent experimental therapies in cancer treatment known as boron neutron capture therapy (BNCT) and gadolinium neutron capture therapy (GdNCT) using a variety of boron- and gadolinium-based compounds. Some of the gadolinium compounds serve the dual purpose as being MRI contrast agents and GdNCT agents. The book describes why BNCT & GdNCT were not at the forefront of the clinical trials during the past seven to eight decades since the discovery of neutrons by John Chadwick in 1932 and how the latest development in the synthesis of target boron- and gadolinium-based drugs has turned the area into the hottest one worthy of further investigation with the new clinical trials in the USA and elsewhere.
Download or read book Cancer Neutron Capture Therapy written by Y. Mishima and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 893 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many human cancers which actively synthesize specific characteristic proteins such as melanomas, thyroid cancer and squamous cell carcinoma. Many cancer researchers have of course tried to utilize this specific activity as a key for the selective treatment of cancers. In the past for example, the molecular hybrid compound of DOPA, a substrate of melanin, and nitrogen mustard N-oxide hydrochloride, a ctyotoxic anti-tumor drug, was synthesized as Melphalan and used to treat malignant melanoma. A major problem arose though in that it was soon found to be highly suppressive toward bone marrow and quite toxic while not being remarkably effective. Thus, malignant melanoma could not be cured by it. Such failure led us to develop a novel bimodal therapeutic system which includes the use of non-toxic potentially cytocidal chemicals which selectively accumulate within the cancer cells and which are converted by a controllable modality into an actively cytocidal element in situ. We can now non-surgically cure malignant melanoma and glioblastoma with our selective cancer treatment, neutron capture therapy (NCT); as can be found in this volume. Included are 124 papers on the latest breaking developments discussed at the Sixth International Symposium on NCT for Cancer held in Kobe during the late autumn of 1994.

Download or read book Silicon Heterojunction Solar Cells written by W.R. Fahrner and published by Trans Tech Publications Ltd. This book was released on 2006-08-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.

Book excerpt: Boron Hydride Chemistry covers the significant contributions of boron hydride research in the subjects of bonding, structure, and stereochemistry. This book contains 12 chapters that illustrate the merging of certain areas of boron hydride chemistry with other disciplines, such as organic, organometallic, and transition metal chemistry. After providing an overview of the general geometric, stereochemical, and dynamic stereochemical features of boron hydrides, this book goes on exploring the bonding theory and theoretical research on boron hydrides, with an emphasis on boron hydrides that have open polyhedral structures. These topics are followed by discussions on gas phase and solution reactions of borane and substituted boranes. A chapter focuses on the chemistry of cations containing boron atoms bonded to hydrogen. The remaining chapters examine the syntheses, structures, bonding, spectral properties, and chemistry of specific boron hydrides, including borazines, closo-boron hydrides, carboranes, icosahedral carboranes, and close- and nido-heteroboranes. Inorganic chemists and researchers, teachers, and undergraduate inorganic chemistry students will find this book invaluable.
