Download or read book Space Radiation Biology and Related Topics written by Cornelius A. Tobias and published by Elsevier. This book was released on 2013-10-22 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space Radiation Biology and Related Topics provides information pertinent to the fundamental aspects of space radiation biology. This book discusses space radiation hazards as well as the importance of natural radiations in the processes of biogenesis. Organized into 12 chapters, this book begins with an overview of the fundamental aspects of radiobiology. This text then discusses the theoretical treatments of the chronic radiation response and the applicability of some of its features in extended manned space missions. Other chapters review the literature on models for recovery from radiation damage to some cellular systems. This book discusses as well the effects of radiations on mammals, with emphasis on those effects pertinent to the space-flight situation. The final chapter deals with the safety of nuclear power in space and explains the three types of nuclear devices designed for power production in space. This book is a valuable resource for radiologists, radiobiologists, and radiotherapists.

Download or read book Optimization of Moisture Content for Wheat Seedling Germination in a Cellulose Acetate Medium for a Space Flight Experiment written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-12-29 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Porous Tube Plant Nutrient Delivery System (PTPNDS), a hydrophilic, microporous ceramic tube hydroponic system designed for microgravity, will be tested in a middeck locker of the Space Shuttle. The flight experiment will focus on hardware operation and assess its ability to support seed germination and early seedling growth in microgravity. The water controlling system of the PTPNDS hardware has been successfully tested during the parabolic flight of the KC-135. One challenge to the development of the spaceflight experiment was to devise a method of holding seeds to the cylindrical porous tube. The seed holder must provide water and air to the seed, absorb water from the porous tube, withstand sterilization, provide a clear path for shoots and roots to emerge, and be composed of flight qualified materials. In preparation for the flight experiment, a wheat seed-holder has been designed that utilizes a cellulose acetate plug to facilitate imbibition and to hold the wheat seeds in contact with the porous tube in the correct orientation during the vibration of launch and the microgravity environment of orbit. Germination and growth studies with wheat at a range of temperatures showed that optimal moisture was 78% (by weight) in the cellulose acetate seed holders. These and other design considerations are discussed. Johnson, Corinne F. and Dreschel, Thomas W. and Brown, Christopher S. and Wheeler, Raymond M.

This book was released on 2018-07-16 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the influence of narrow-spectrum red light-emitting diodes (LED's) on plant growth and seed production, wheat (Triticum aestivum L.cv Superdwarf) and Arabidopsis (Arabidopsis thaliana (L.) Heynh, race Columbia) plants were grown under red LED's (peak emission 660 nm) and compared to plants grown under daylight fluorescent (white) light and red LED's supplemented with either 1 percent or 10 percent blue fluorescent (BF) light. Wheat growth under red LED's alone appeared normal, whereas Arabidopsis under red LED's alone developed curled leaf margins and a spiraling growth pattern. Both wheat and Arabidopsis under red LED's alone or red LED's + 1 percent BF light had significantly lower seed yield than plants grown under white light. However, the addition of 10 percent BF light to red LED's partially alleviated the adverse effect of red LED's on yield. Irrespective of the light treatment, viable seeds were produced by wheat(75-92 percent germination rate) and Arabidopsis (85-100 percent germination rate). These results indicate that wheat, and to a lesser extent Arabidopsis, can be successfully grown under red LED's alone, but supplemental blue light is required with red LED's to sufficiently match the growth characteristics and seed yield associated with plants grown under white light.

This book was released on 2002 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat is the most widely grown cereal crop in the world, with an ever increasing demand. It plays a fundamental role in food security, and a major challenge is to meet the additional requirements with new cultivars and improved cropping technologies. This book covers information from a number of international experts on the current status of research on wheat improvement and production (wheat breeding programs and genetics), as well as on other aspects (including wheat diseases), from its evolutionary origins to seed production technologies.

Download or read book A Strategy for Research in Space Biology and Medicine in the New Century written by National Research Council and published by National Academies Press. This book was released on 1998-09-16 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction of the international space station, scheduled to start in late 1998, ushers in a new era for laboratory sciences in space. This is especially true for space life sciences, which include not only the use of low gravity as an experimental parameter to study fundamental biological processes but also the study of the serious physiological changes that occur in astronauts as they remain in space for increasingly longer missions. This book addresses both of these aspects and provides a comprehensive review of ground-based and space research in eleven disciplines, ranging from bone physiology to plant biology. It also offers detailed, prioritized recommendations for research during the next decade, which are expected to have a considerable impact on the direction of NASA's research program. The volume is also a valuable reference tool for space and life scientists.
Download or read book Radiation in Medicine and Biology written by Pandit B. Vidyasagar and published by CRC Press. This book was released on 2017-05-08 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the conventional and emerging applications of radiations, which include radio waves and ultraviolet and gamma radiations. It discusses new techniques in radiation therapy and the effects of ionizing radiations on biological systems. The applications of radiations in the synthesis and use of nanoparticles along with the effects of hypergravity indicate a new trend. The book offers a concise account of the latest studies carried out so far and shows the new initiatives to be undertaken in the field of medicine and biology. It covers the medical use of radiations, such as ferrous sulfate–benzoic acid–xylenol orange dosimetry, Co-60 tomotherapy, radio-electro-chemotherapy, and fractional radiotherapy, and radiobiological effects, such as the effects of cell phone radiations on human health parameters and the combined effects of radiations and hypergravity on plants.
