Book excerpt: Under the High Pressure Earth Storable Rocket Technology (HIPES) Program, TRW successfully completed testing of two 100 lbf thrust class rhenium chambers using N204-MMH. The first chamber was successfully fired for 4789 seconds of operating time with a maximum duration of 700 seconds. This chamber had been previously fired for 5230 seconds with N2O4-N2H4. The second chamber was successfully fired for 8085 seconds with a maximum firing duration of 1200 seconds. The Isp (specific impulse) for both chambers ranged from 323 lbf-sec/lbm to 330 lbf-sec/lbm.Chazen, M.

This book was released on 2018-07-08 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The HIPES Program was conducted for NASA-LeRC by TRW. The Basic Program consisted of system studies, design of testbed engine, fabrication and testing of engine. Studies of both pressure-fed and pump-fed systems were investigated for N2O4 and both MMH and N2H4 fuels with the result that N2H4 provides the maximum payload for all satellites over MMH. The higher pressure engine offers improved performance with smaller envelope and associated weight savings. Pump-fed systems offer maximum payload for large and medium weight satellites while pressure-fed systems offer maximum payload for small light weight satellites. The major benefits of HIPES are high performance within a confined length maximizing payload for lightsats which are length (volume) constrained. Three types of thrust chambers were evaluated -- Copper heatsink at 400, 500 and 600 psia chamber pressures for performance/thermal; water cooled to determine heat absorbed to predict rhenium engine operation; and rhenium to validate the concept. The HIPES engine demonstrated very high performance at 50 lbf thrust (epsilon = 150) and Pc = 500 psia with both fuels: Isp = 337 sec using N2O4-N2H4 and ISP = 327.5 sec using N2O4-MMH indicating combustion efficiencies greater than 98%. A powder metallurgy rhenium engine demonstrated operation with high performance at Pc = 500 psia which indicated the viability of the concept. Chazen, M.

Download or read book LSD My Problem Child written by Albert Hofmann and published by Multidisciplinary Association for Psychedelic Studies. This book was released on 2017-09-27 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of LSD told by a concerned yet hopeful father, organic chemist Albert Hofmann, Ph.D. He traces LSD's path from a promising psychiatric research medicine to a recreational drug sparking hysteria and prohibition. In LSD: My Problem Child, we follow Dr. Hofmann's trek across Mexico to discover sacred plants related to LSD, and listen in as he corresponds with other notable figures about his remarkable discovery. Underlying it all is Dr. Hofmann's powerful conclusion that mystical experiences may be our planet's best hope for survival. Whether induced by LSD, meditation, or arising spontaneously, such experiences help us to comprehend "the wonder, the mystery of the divine, in the microcosm of the atom, in the macrocosm of the spiral nebula, in the seeds of plants, in the body and soul of people." More than sixty years after the birth of Albert Hofmann's problem child, his vision of its true potential is more relevant, and more needed, than ever.

Download or read book Space Tourism written by Michel van Pelt and published by Springer Science & Business Media. This book was released on 2005-03-09 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many scientific papers and popular articles have been written on the topic of space tourism, describing everything from expected market sizes to the rules of 3-dimensional microgravity football. But what would it actually feel like to be a tourist in space, to be hurled into orbit on top of a controlled explosion, to float around in a spacecraft, and to be able to look down on your hometown from above the atmosphere? Space tourism is not science fiction anymore, Michel van Pelt tells us, but merely a logical step in the evolution of space flight. Space is about to be opened up to more and more people, and the drive behind this is one of the most powerful economic forces: tourism. Van Pelt describes what recreational space travel might look like, and explains the required space technology, the medical issues, astronaut training, and the possibilities of holidays to destinations far, far away. This is a book for everyone who has ever dreamed of traveling to space: a dream which, according to van Pelt, may not be so far from becoming a reality. Consider it the armchair traveler's guide to the coming boom in space tourism.

Download or read book OZONE written by Velio Bocci and published by Springer Science & Business Media. This book was released on 2010-10-05 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen-Ozone therapy is a complementary approach less known than homeopathy and acupuncture because it has come of age only three decades ago. This book clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classical biochemistry, physiological and pharmacological knowledge. Ozone is an oxidizing molecule, a sort of super active oxygen, which, by reacting with blood components generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes and cancer. Moreover, by inducing nitric oxide synthase, ozone therapy may mobilize endogenous stem cells, which will promote regeneration of ischemic tissues. The description of these phenomena offers the first comprehensive picture for understanding how ozone works and why. When properly used as a real drug within therapeutic range, ozone therapy does not only does not procure adverse effects but yields a feeling of wellness. Half the book describes the value of ozone treatment in several diseases, particularly cutanious infection and vascular diseases where ozone really behaves as a “wonder drug”. The book has been written for clinical researchers, physicians and ozone therapists, but also for the layman or the patient interested in this therapy.

Download or read book The Space Shuttle Program written by Davide Sivolella and published by Springer. This book was released on 2017-06-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells the story of the Space Shuttle in its many different roles as orbital launch platform, orbital workshop, and science and technology laboratory. It focuses on the technology designed and developed to support the missions of the Space Shuttle program. Each mission is examined, from both the technical and managerial viewpoints. Although outwardly identical, the capabilities of the orbiters in the late years of the program were quite different from those in 1981. Sivolella traces the various improvements and modifications made to the shuttle over the years as part of each mission story. Technically accurate but with a pleasing narrative style and simple explanations of complex engineering concepts, the book provides details of many lesser known concepts, some developed but never flown, and commemorates the ingenuity of NASA and its partners in making each Space Shuttle mission push the boundaries of what we can accomplish in space.Using press kits, original papers, newspaper and magazine articles, memoirs and interviews, this book provides the most up-to-date and comprehensive account available of the shuttle’s many missions and will refocus interest on a remarkable flying machine and space program that is often pushed to the background.

This book was released on 2012-12-06 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Conference on the State of the Art on Biogas Technology, Transfer and Diffusion was held in Cairo, Egypt, from 17 to 24 November 1984. The Conference was organized by the Egyptian Academy of Scientific Research and Technology (ASR T), the Egyptian National Research Centre (NRC), the Bioenergy Systems and Technology project (BST) of the US Agency for International Development (US/AID) Office of Energy, and the National Academy of Sciences (NAS). A number of international organizations and agencies co-sponsored the Conference. More than 100 participants from 40 countries attended. The purpose of the Conference was to assess the viability of biogas technology (BGT) and propose future courses of action for exploiting BGT prospects to the fullest extent. The Conference emphasized a balanced coverage of technical, environ mental, social, economic and organizational aspects relevant to biogas systems design, operation and diffusion. It was organized to incorporate experiences that are pertinent, for the most part, to developing countries. In addition to the wide spectrum of presentations and country programs, structured and non-structured discussions among the participants were strongly encouraged in thematic sessions at round-table discussions, and through personal contacts during poster sessions and field trips. It was clear from the enthusiastic response of most participants that the Conference, in large measure, succeeded in fulfilling its mission. Although draft papers were distributed to all participants, it was felt that the results obtained were worthy of organized and refined documentation. And this is precisely what this book intends to do.

Download or read book Principles and Applications of Modified Atmosphere Packaging of Foods written by R. T. Parry and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modified atmosphere packaging (MAP) has proved to be one of the most significant and innovative growth areas in retail food packaging of the past two decades. Bulk modified atmosphere packs have been an accepted form of packaging for meat and poultry in the USA since the early 1970s, but MAP is only now of being widely adopted. Today there is a substantial wholesale on the verge market for bulk packaged fresh vegetables and fruit, and the most significant retail MAP products are fresh pasta, pre-cooked poultry and sausage, and biscuits (a unique American product). The United Kingdom is the biggest single market for the modified atmosphere packaging of fresh chilled food products, accounting for about half of the total European market. A further quarter is represented by France. The success of MAP in both the British and French markets can be attributed to the large, highly sophisticated food retailing multiples and dense populations existing in both countries.

Download or read book The Earth Care Manual written by Patrick Whitefield and published by Permanent Publications. This book was released on 2004 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-awaited exploration of permaculture specifically for cooler Northern Hemisphere climates is finally here! Already regarded as the definitive book on the subject, The Earth Care Manual is accessible to the curious novice as much as it is essential for the knowledgeable practitioner. Permaculture started out in the 1970s as a sustainable alternative to modern agriculture, taking its inspiration from natural ecosystems. It has always placed an emphasis on gardening, but since then it has expanded to include many other aspects, from community design to energy use. It can be seen as an overall framework that puts a diversity of green ideas into perspective. Its aims are low work, high output, and genuine sustainability.

Download or read book Social Media in Industrial China written by Xinyuan Wang and published by UCL Press. This book was released on 2016-09-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life outside the mobile phone is unbearable.’ Lily, 19, factory worker. Described as the biggest migration in human history, an estimated 250 million Chinese people have left their villages in recent decades to live and work in urban areas. Xinyuan Wang spent 15 months living among a community of these migrants in a small factory town in southeast China to track their use of social media. It was here she witnessed a second migration taking place: a movement from offline to online. As Wang argues, this is not simply a convenient analogy but represents the convergence of two phenomena as profound and consequential as each other, where the online world now provides a home for the migrant workers who feel otherwise ‘homeless’. Wang’s fascinating study explores the full range of preconceptions commonly held about Chinese people – their relationship with education, with family, with politics, with ‘home’ – and argues why, for this vast population, it is time to reassess what we think we know about contemporary China and the evolving role of social media.

Download or read book Space Storable Rocket Technology Program Ssrt Option 1 Program written by National Aeronautics and Space Adm Nasa and published by . This book was released on 2018-11-08 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Space Storable Rocket Technology (SSRT) Option 1 Program was initiated in October 1991 after completion of the Basic Program. The program was restructured in mid-July 1992 to incorporate a Rhenium Technology Task and reduce the scope of the LO2-N2H4 engine development. The program was also extended to late February 1993 to allow for the Rhenium Technology Task completion. The Option 1 Program was devoted to evaluation of two new injector elements, evaluation of two different methods of thermal protection of the injector, evaluation of high temperature material properties of rhenium and evaluation of methods of joining the rhenium thrust chamber to the columbium injector and nozzle extension. In addition, critical experiments were conducted (Funded by Option 2) to evaluate mechanisms to understand the effects of GO2 injection into the chamber, helium injection into the main LO2, effect of the splash plate and effect of decreasing the aspect ratio of the 120-slot (-13a) element. The performance and thermal models were used to further correlate the test results with analyses. The results of the work accomplished are summarized.
