Alternative Toxicological Methods By Harry Salem, Sidney A. Katz 2003 | 617 Pages | ISBN: 084931528X | PDF | 8 MB Bringing together the recent and relevant contributions of over 125 scientists from industry, government, and academia in North America and Western Europe, Alternative Toxicological Methods explores the development and validation of replacement, reduction, and refinement alternatives (the 3Rs) to animal testing. Internationally recognized scientists present what has been accomplished thus far in developing acceptable alternatives to traditional animal toxicological assessment and provide potentially new initiatives.In over 40 chapters, the book addresses 7 themes, beginning with the validation and regulatory acceptance of alternatives in the US, the UK, and Western Europe. Then the book covers methods based on the mechanisms of eye irritation at the ocular surface, dermal toxicity testing, and assessing neurotoxicity. It also includes a case study in the use of alternatives to determine the mechanism of sulfur mustard action and discusses the role of transgenics and toxicokinetics in the development of alternative toxicity tests. Finally the book presents recent innovations in alternatives, including the use of archival data, and in silico techniques.Focusing on the science and not the politics, Alternative Toxicological Methods concisely discusses the application of state-of-the-art methods and explores cutting-edge research related to developing and validating alternatives to animal testing. This book will benefit toxicologists, cosmetic chemists, pharmacologists, experimental biologists, dermatologists, ophthalmologists, and regulatory officers in their quest for applying the 3Rs to the use of animals in toxicological testing of drug candidates, chemicals, and cosmetics.  All at Sea by John Cooke English | December 19th, 2020 | ISBN: 1800460740 | 344 pages | True EPUB | 3.65 MB One man's voyage through life  Algorithmic Thinking: A Problem-Based Introduction by Daniel Zingaro English | December 15, 2020 | ASIN: B085BVJ51Z, ISBN: 1718500807 | AZW3 | 408 pages | 6.2 MB A hands-on, problem-based introduction to building algorithms and data structures to solve problems with a computer.  Alaska: Saga of a Bold Land By Walter R. Borneman 2004 | 632 Pages | ISBN: 0060503076 | PDF | 6 MB The history of Alaska is filled with stories of new land and new riches -- and ever present are new people with competing views over how the valuable resources should be used: Russians exploiting a fur empire; explorers checking rival advances; prospectors stampeding to the clarion call of ''Gold!''; soldiers battling out a decisive chapter in world war; oil wildcatters looking for a different kind of mineral wealth; and always at the core of these disputes is the question of how the land is to be used and by whom.While some want Alaska to remain static, others are in the vanguard of change. Alaska: Saga of a Bold Land shows that there are no easy answers on either side and that Alaska will always be crossing the next frontier.  Steven E. Jones, "Against Technology: From the Luddites to Neo-Luddism" English | 2006 | pages: 290 | ISBN: 0415978688 | PDF | 4,5 mb This book addresses the question of what it might mean today to be a Luddite-that is, to take a stand against technology. Steven Jones here explains the history of the Luddites, British textile works who, from around 1811, proclaimed themselves followers of "Ned Ludd" and smashed machinery they saw as threatening their trade. Against Technology is not a history of the Luddites, but a history of an idea: how the activities of a group of British workers in Yorkshire and Nottinghamshire came to stand for a global anti-technology philosophy, and how an anonymous collective movement came to be identified with an individualistic personal conviction. Angry textile workers in the early nineteenth century became romantic symbols of a desire for a simple life-certainly not the original goal of the actions for which they became famous. Against Technology is, in other words, a book about representations, about the image and the myth of the Luddites and how that myth was transformed over time into modern neo-Luddism.  P. Van Mele, Jeffrey W. Bently, Robert. G Guei, "African Seed Enterprises: Sowing the Seeds of Food Security" English | ISBN 10: 1845938437 | 2011 | PDF | 224 pages | 3,7 MB In most developing countries, good quality seed is hard to obtain and farmers struggle to save seed from one year to the next. Instead, they increasingly turn to public or private enterprises that multiply, store and distribute seed.  Patricia Ann Lynch, "African Mythology A to Z" English | ISBN: 0816048924 | 2004 | 137 pages | PDF | 3 MB Alphabetically listed entries discuss the myths, traditions, beliefs, and characters of African mythology.  Abdelmejid Benamara, Mohamed Haddar, Benameur Tarek, "Advances in Mechanical Engineering and Mechanics" English | 2019 | ISBN: 3030197808 | PDF | pages: 285 | 43.8 mb This book reports on original theoretical and experimental findings related to a number of cutting-edge topics in mechanics and mechanical engineering, such as structure modelling and computation; design methodology and manufacturing processes; mechanical behaviour of materials; fluid mechanics and energy; and heat and mass transfer. It includes a selection of papers presented at the 4th Tunisian Congress on Mechanics, CoTuMe'2018, held in Hammamet, Tunisia, on October 13-15, 2018. Thanks to the good balance of theory and practical findings, it offers a timely snapshot for researchers and industrial communities alike, and a platform to facilitate communication and collaboration between the two groups.  Magdalena Diering, Michał Wieczorowski, Christopher A. Brown, "Advances in Manufacturing II: Volume 5 - Metrology and Measurement Systems" English | 2019 | ISBN: 3030186814 | PDF | pages: 313 | 79.3 mb This book gathers timely contributions on metrology and measurement systems, across different disciplines and field of applications. The chapters, which were presented at the 6th International Scientific-Technical Conference, MANUFACTURING 2019, held on May 19-21, 2019, in Poznan, Poland, cover cutting-edge topics in surface metrology, biology, chemistry, civil engineering, food science, material science, mechanical engineering, manufacturing, metrology, nanotechnology, physics, tribology, quality engineering, computer science, among others. By bringing together engineering and economic topics, the book is intended as an extensive, timely and practice-oriented reference guide for both researchers and practitioners. It is also expected to foster better communication and closer cooperation between universities and their business and industry partners.
