Download or read book Characterization of the SCP 1021 Aerosol Sampler written by and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study characterized the SCP 1021 aerosol sampler (SCP Dynamics, Inc., Minneapolis, MN) at flow rates of 1350 L/min and 1000 L/min. Polydisperse aluminum oxide (Al2O3) particles were used as the solid particles, and the analysis was by Coulter counter. Fluorescent oleic acid particles were used as the monodisperse liquid particles, and the analysis was by fluorometry. The results show that: (1) the sampling efficiency curves for both solid and liquid particles have a peak at approximately 5-6 micrometers, (2) there are no significant differences between the sampling efficiencies of the 1350 and 1000 L/min air flow rates, (3) there is no difference in sampling efficiency between the liquid and solid particles for particles smaller than 6 micrometers; however, large (> 6 micrometers) solid particles bounce when they hit surfaces and are carried by the air to the collection site, resulting in higher sampling efficiency for solid particles, (4) removing the inlet cap and the pre-collector increases the sampling efficiency for particles larger than approximately 4 micrometers, and (5) washing the final stage stem shows that there is significant particle loss in the stem that takes the aerosol to the liquid impaction/bubbling site.

Download or read book Sensor Systems for Biological Agent Attacks written by National Research Council and published by National Academies Press. This book was released on 2005-12-11 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last ten years, there has been growing concern about potential biological attacks on the nation's population and its military facilities. It is now possible to detect such attacks quickly enough to permit treatment of potential victims prior to the onset of symptoms. The capability to "detect to warn", that is in time to take action to minimize human exposure, however, is still lacking. To help achieve such a capability, the Defense Threat Reduction Agency (DTRA) asked the National Research Council (NRC) to assess the development path for "detect to warn" sensors systems. This report presents the results of this assessment including analysis of scenarios for protecting facilities, sensor requirements, and detection technologies and systems. Findings and recommendations are provided for the most probable path to achieve a detect-to-warn capability and potential technological breakthroughs that could accelerate its attainment.

Download or read book Microscale Acoustofluidics written by Thomas Laurell and published by Royal Society of Chemistry. This book was released on 2014-12-08 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: The manipulation of cells and microparticles within microfluidic systems using external forces is valuable for many microscale analytical and bioanalytical applications. Acoustofluidics is the ultrasound-based external forcing of microparticles with microfluidic systems. It has gained much interest because it allows for the simple label-free separation of microparticles based on their mechanical properties without affecting the microparticles themselves. Microscale Acoustofluidics provides an introduction to the field providing the background to the fundamental physics including chapters on governing equations in microfluidics and perturbation theory and ultrasound resonances, acoustic radiation force on small particles, continuum mechanics for ultrasonic particle manipulation, and piezoelectricity and application to the excitation of acoustic fields for ultrasonic particle manipulation. The book also provides information on the design and characterization of ultrasonic particle manipulation devices as well as applications in acoustic trapping and immunoassays. Written by leading experts in the field, the book will appeal to postgraduate students and researchers interested in microfluidics and lab-on-a-chip applications.
Download or read book A Stratigraphical Basis for the Anthropocene written by C.N. Waters and published by Geological Society of London. This book was released on 2014-06-05 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humankind has pervasively influenced the Earth’s atmosphere, biosphere, geosphere, hydrosphere and cryosphere, arguably to the point of fashioning a new geological epoch, the Anthropocene. To constrain the Anthropocene as a potential formal unit within the Geological Time Scale, a spectrum of indicators of anthropogenically-induced environmental change is considered, and shown as stratigraphical signals that may be used to characterize an Anthropocene unit, and to recognize its base. This volume describes a range of evidence that may help to define this potential new time unit and details key signatures that could be used in its definition. These signatures include lithostratigraphical (novel deposits, minerals and mineral magnetism), biostratigraphical (macro- and micro-palaeontological successions and human-induced trace fossils) and chemostratigraphical (organic, inorganic and radiogenic signatures in deposits, speleothems and ice and volcanic eruptions). We include, finally, the suggestion that humans have created a further sphere, the technosphere, that drives global change.
Download or read book Physical and Chemical Processes in the Aquatic Environment written by Erik R. Christensen and published by John Wiley & Sons. This book was released on 2014-09-15 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.
