This book was released on 2021-10-30 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanofiber Filter Technologies for Filtration of Submicron Aerosols and Nanoaerosols covers the nanoaerosols (less than 100 nanometers) to larger submicron aerosols due mostly to pollution, which are present in high number concentration in our surroundings. People are breathing these nanoaerosols daily without being aware of it. Airborne viruses from flu to coronaviruses are also nanoaerosols. During the COVID-19 pandemic, it took a long time for health authorities and the General Public to recognize the airborne transmission mode of the virus. This leads to inadequate protection and ineffective virus control strategies resulting in high infection and death rates. The book cites evidence and observations pointing to the airborne transmission mode of the coronavirus. It also discusses different filtration technologies using nanofibers to capture these aerosols for short-term filtration, where aerosols are trapped in the filter (depth filtration), and long-term filtration, where aerosols are trapped in the growing filter cake (cake filtration). This book provides a good understanding on how nanofibers, which is of size 1/1000 times that of a normal human hair, can effectively filter these tiny aerosols. NFT, organized in four sections – fundamentals, deep understanding, technologies, and application, covering comprehensively on the subject, is a valuable resource for undergraduates and graduates, engineers, researchers and practitioners in related industries. Describes technologies with insight and use basic engineering principles to build-up technologies Includes extensive clear and understandable figures and tables to enhance key concepts Uses examples throughout to explain engineering principles and interdisciplinary concepts The only book in the market focusing on nanofiber filter technologies for filtering submicron aerosols and nanoaerosols

Download or read book Vasculopathies written by Marc Thiriet and published by Springer. This book was released on 2019-02-18 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents one of the clinical foundations of vasculopathies: the biological markers and risk factors associated with cardiovascular disease. A detailed biological and clinical framework is provided as a prerequisite for adequate modeling. Chapter 1 presents cardiovascular risk factors and markers, where the search for new criteria is aimed at improving early detection of chronic diseases. The subsequent chapters focus on hypertension, which involves the kidney among other organs as well as many agents, hyperglycemia and diabetes, hyperlipidemias and obesity, and behavior. The last of these risk factors includes altered circadian rhythm, tobacco and alcohol consumption, physical inactivity, and diet. The volumes in this series present all of the data needed at various length scales for a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to nano- and microscopic events in a corrector scheme of regulated mechanisms. Therefore, investigation of flows of blood and air in anatomical conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning in quantitative terms.

Book Synopsis Living with Covid-19 by : Chaudhery Mustansar Hussain
Download or read book Living with Covid-19 written by Chaudhery Mustansar Hussain and published by . This book was released on 2021-11-25 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the end of 2019, the world came across a virus, SARS-CoV-2. This new coronavirus produces the disease classified as COVID-19. The virus is highly transmissible and causes an acute respiratory syndrome that ranges from mild cases in about 80% to very severe cases with respiratory failure that varies between 5% and 10% of cases. The World Health Organization has declared the outbreak of COVID-19 to be a pandemic, classifying it a high global risk. The epicenter of the outbreak of this pandemic was the city of Wuhan in China's Hubei Province. The risk assessment for COVID-19 depends on the characteristics of the virus, including how it spreads among people. Among the risks, we have is the risk of exposure, and in this way we can assess occupational exposure to waste from health services. Human health risk assessment is a process of gathering and analyzing environmental and health information using specific techniques to support decision making and the execution, systematically, of actions and articulation within and between sectors for the use and promotion of health, improving the social and living conditions of populations. The risk assessment for COVID-19 needs to consider and document all relevant information available at the time of assessment. In this way, decision making will be directed and a record of the process will be provided, including which risks and control measures were evaluated, the methods used to evaluate them, why they were considered important, and their order of priority. In this sense, if documented in a consistent manner, risk assessment may provide a record of the justification for changes throughout the event, including the level of risk assessed, recommended control measures, and key decisions and actions that will be fundamental to be considered in the face of the coronavirus pandemic. This book addresses the new challenges of COVID-19 in detail with up-to-date knowledge on safety risk, economics, and ELSI of COVID-19.
