Nanofiber Filter Technologies for Filtration of Submicron Aerosols and Nanoaerosols by Wallace Woon-Fong Leung Pdf

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

Nanoaerosols, Air Filtering and Respiratory Protection by Katarzyna Majchrzycka Pdf

Recent toxicological studies show that nanoparticles released in technological processes and combustion processes outside industry can be dangerous for humans especially when entering the body through the mouth and nose. In connection with the above, the use of adequately effective respiratory protection equipment is of great importance in prophylactic and preventive activities. The first part of Nanoaerosols, Air Filtering and Respiratory Protection: Science and Practice refers to the general phenomena of filtration described on the basis of the authors’ own experience and international reports. The book also includes a description of the respiratory system and principles of its functioning and the accumulation of aerosol particles. It goes on to discuss technological innovations regarding the production of filtering materials for protection against nanoparticles and the latest test methods. Finally, the book contains information about the proper selection and use of respiratory protective devices against airborne nanoparticles in the workplace and everyday life. Special attention is paid to proper fit procedures as well as use and maintenance activities of such devices. The content of the book with rich illustrative material has been presented so that it can be used by health and safety experts, students as well as employers, employees and private users of respiratory protective devices. "Through a comprehensive approach to the subject of the work, the authors present theoretical foundations as well as practical solutions that are used in the research and development of personal respiratory protection. The complementarity of the information contained in the book will allow the reader to become familiar with a wide range of knowledge related to the design and manufacture as well as assessment of properties and procedures for the use of respiratory protection against the adverse effects of aerosols, including air contaminated with nanoparticles and microparticles. In my opinion the book is a valuable part of the series Occupational Safety, Health, and Ergonomics: Theory and Practice, published by Taylor & Francis." —Maciej Boguń, ŁUKASIEWICZ – The Textile Research Institute, Łódź

Aerosol Filtration by Dominique Thomas,Augustin Charvet,Nathalie Bardin-Monnier,Jean-Christophe Appert-Collin Pdf

Filtration of aerosols is omnipresent in our daily lives, in areas as diverse as health, the protection of people and the environment, and air treatment inside buildings. However, the collection of particles within a filter media is not, contrary to popular belief, linked to a simple screen effect. The phenomena involved are much more complex and require the consideration of aerosol interactions, filter media and process conditions to select the best fiber filter for a given application. Aerosol Filtration, book for students, hygiene or process engineers, fibrous media manufacturers, designers, and filtration system suppliers or users addresses the filtration of aerosols in six chapters. These chapters cover physics and aerosol characterization, the fibrous media, and efficiency and filter clogging by solid or liquid aerosols, with special attention to the filtration of the nanoparticles. Analyses the behavior of fibrous media against solid and liquid aerosols Presents models of efficiency and pressure drop Introduces computing elements for estimating the lifetime of filters Provides guidance for designing filters and predicting their behavior over time

Reusability of Facemasks During an Influenza Pandemic by Institute of Medicine,Board on Health Sciences Policy,Committee on the Development of Reusable Facemasks for Use During an Influenza Pandemic Pdf

Any strategy to cope with an influenza pandemic must be based on the knowledge and tools that are available at the time an epidemic may occur. In the near term, when we lack an adequate supply of vaccine and antiviral medication, strategies that rely on social distancing and physical barriers will be relatively more prominent as means to prevent spread of disease. The use of respirators and facemasks is one key part of a larger strategy to establish barriers and increase distance between infected and uninfected individuals. Respirators and facemasks may have a role in both clinical care and community settings. Reusability of Facemasks During an Influenza Pandemic: Facing the Flu answers a specific question about the role of respirators and facemasks to reduce the spread of flu: Can respirators and facemasks that are designed to be disposable be reused safely and effectively? The committee-assisted by outstanding staff-worked intensively to review the pertinent literature; consult with manufacturers, researchers, and medical specialists; and apply their expert judgment. This report offers findings and recommendations based on the evidence, pointing to actions that are appropriate now and to lines of research that can better inform future decisions.

Vasculopathies by Marc Thiriet Pdf

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.

Living with Covid-19 by Chaudhery Mustansar Hussain,Gustavo Marques da Costa Pdf

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.
