Free Download Lei Wu, "Rarefied Gas Dynamics: Kinetic Modeling and Multi-Scale Simulation" English | ISBN: 9811928711 | 2022 | 305 pages | EPUB | 66 MB This book highlights a comprehensive description of the numerical methods in rarefied gas dynamics, which has strong applications ranging from space vehicle re-entry, micro-electromechanical systems, to shale gas extraction.  Free Download Rasel Das, "Rapid Refrigeration and Water Protection: Next Generation Adsorbents " English | ISBN: 3030938441 | 2022 | 273 pages | EPUB | 41 MB This book provides a cross-disciplinary, multi-scale assessment of the development of adsorption-based refrigerants and super-adsorbent-based wastewater purification. The book covers two major aspects from the 21st century, including the development of an environmentally benign adsorption cooling system and the preparation of a super-adsorbent for water purification. Although work has been published on these topics, the authors present the latest findings and introduce some new perspectives. The book is written as a reference book with contributions from global field experts and will appeal to water engineers, chemists, environmentalists, physicists, material scientists, nano-technologists, and environmental technologists.

The development of all heavy automatic weapons of every nation during the 20th century is explained with easily understood technical descriptions of mountings, sights, ammunition feeds, and other mechanisms. Analyses of the weapons are presented in the historical contexts in which they were developed, and photos depict the weapons in use. Line drawings and a look into the future of heavy weapons.  Free Download Howell G. M. Edwards, "Raman Spectroscopy in Cultural Heritage Preservation " English | ISBN: 3031143787 | 2023 | 531 pages | EPUB | 44 MB This book addresses the application of Raman spectroscopic techniques to a range of diverse problems which arise in the study, conservation and restoration of artefacts and sites closely related to our cultural heritage as well as in authentication. These themes are naturally wider than what at first might be considered as artworks and archaeological artefacts and the topics include pigments, paintings, ceramics, glass, sculpture and patination / corrosion, textiles, industrial archaeology, the degradation and preservation of biomaterials, mummies and human skeletal remains. An interesting feature is the inclusion of modern case studies which describe specific problems and approaches to the Raman spectral analysis of items important to our cultural heritage. The text is prefaced with an introduction to the important parameters used in nondestructive Raman measurements and also highlights some future applications based upon novel miniaturised instrumentation for in-field studies andpotential screening work which will identify specimens which would repay further studies in the laboratory. An attempt is made to give a snapshot of the state-of-the-art evolution since the beginning of the technique (1970s) and to point out potential further development. The book is co-edited by three international experts with many years' experience in the application of Raman spectroscopy to artworks, archaeological artefacts and in the investigation of materials and sites for cultural heritage preservation and each editor has undertaken to write individual chapters and different topics personally. The adopted approach is designed to convey the sort of information which has become available from the adoption of analytical Raman spectroscopy to different problems in the field of cultural heritage preservation through the spectral interrogation of artefacts and how the interpretation of the spectral data can assist museum curators, archaeologists and cultural heritage historians in the preservation and conservation of ancient materials and sites : a particular advantage in this respect is the ability of Raman spectroscopy to determine -generally in a strictly noninvasive procedure - at the laboratory or on-site with mobile instruments, the presence of both organic and inorganic components in a particular specimen together nondestructively without any chemical and mechanical pretreatment being undertaken, which is an essential requirement for rare and valuable samples . An important aside from this work is the means of spectral identification of ongoing biodeterioration and biological colonisation in specimens in storage and the effects of environmental deterioration such as humidity and temperature upon their integrity.  Free Download Ian Hembrow, "Ralph Edwards: RARE EVENTS: The Inside Story of a Worldwide Quest for Safer Medicines " English | ISBN: 3031149807 | 2023 | 512 pages | EPUB | 133 MB Medical treatments designed to help people can also be harmful or fatal. Around 2.5 million people die this way each year. So if any kind of medicine makes someone unwell, they or their doctor should report it. Those reports, from nearly every country in the world, go to the Uppsala Monitoring Centre (UMC) in Sweden.  Free Download Aysha Akter, "Rainwater Harvesting―Building a Water Smart City " English | ISBN: 3030946428 | 2022 | 294 pages | EPUB | 62 MB This book introduces the readers to possible aspects of the rainwater harvesting system against urbanization to plan, design, and implement. Practical applications of rainwater harvesting to supplement potable water, stormwater management, greywater reuse, and managed aquifer recharge are included. Along with conventional practices, advanced technologies for conceptualizing, data collection and processing, test procedures, and design principles are provided to illustrate the theory. This book is a pathway to a water smart city, example problems reflect the solutions for harvested water quantity and/or quality and afterward. Socio-economic assessments are incorporated to explore comprehensive knowledge. |
