Available in PDF, EPUB and Kindle. Book excerpt: Biological warfare (BW) agents are a prime concern to both military and civilian personnel because of both their lethality and the resulting terror they would inflict upon a population. Dc testing and identifying aerosols is a primary objective of the US DoD and many other institutions worldwide. Light scattering may provide an automated means of rapidly detecting and identifying potentially lethal aerosols real-time without the use of chemical reagents or expensive maintenance. Since organic particles tend to fluoresce, many detector systems have focused on measuring this property to identify potentially harmful particles to raise an alarm. However, because fluorescence signals tend to be weak and smooth, it is difficult to differentiate among species of biological particles. Natural backgrounds vary widely and may cause false alarms. For this reason, other information is needed about the particle system that may be gathered from the elastic scattering spectrum. One property of 3W agents is that when they are aerosolized, they tend to aggregate into clusters. From the scattering signal, it might be possible to characterize the individual spores making up the cluster to help in the identification. However, again it is essential to be aware of the natural background signals caused by dust, diesel fumes, pollen, etc. and to develop methods to distinguish between these particles and the particles of concern.

Available in PDF, EPUB and Kindle. Book excerpt: Photopolarimetric remote sensing is vital in fields as diverse as medical diagnostics, astrophysics, atmospheric science, environmental monitoring and military intelligence. The areas considered here include: radiative transfer; dynamic systems; backscatter polarization; biological systems; astrophysical phenomena; comets; and instrumentation. Subtopics include observational information including determining morphology and chemistry, light-scattering models, and characterization methodologies. While this introductory text highlights the latest advances in this multi-disciplinary topic, it is also a reference guide for the advanced researcher.
Download or read book Cometary Science after Hale Bopp written by Hermann Böhnhardt and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comet Hale-Bopp defines a milestone event for cometary science: it is the first "really big" comet observed with modern equipment on the ground and from space and due to that; it is considered the new reference object in cometary sciences. At the beginning of a new era in spacecraft exploration of comets and five years after Hale-Bopp's perihelion passage these proceedings of invited and contributed papers for IAU Colloquium 186 "Cometary Science after Hale-Bopp" review the state-of-the-art knowledge on comets, the icy, dusty and most primordial left-overs of the formation disk of our own solar system.
Download or read book NATO Advanced Research Workshop Optics of Biological Particles Held in Novosibirsk Russia on 3 6 Oct 2005 written by and published by . This book was released on 2005 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Included within this volume are the abstracts to be presented at the NATO Advanced Research Workshop on Optics of Biological Particles. The meeting's focus is on the potential of light scattering in the detection of biological agents, on novel detection systems using polarized light scattering, imaging (microscopy), inelastic scattering, absorption and emission over all EM spectral regions. The aim is to bring together researchers from different fields (physics, biophysics, microbiology, cytology, etc) to foster the flow of information between these diverse groups of researchers. Most of all, we hope that the workshop results in new collaborations that improve research efficiency.

This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Research Workshop on 'Frontiers of Optical Phenomena in Semiconductor Structures of Reduced Dimensions provided a forum in which experimental and theoretical physicists discussed and evaluated recent developments in the optical research of the exciting new phenomena that occur in the electron systems of semiconductor nanostructures. The topics of principal interest to the participants included the integral and fractional quantum Hall effects, the nonlinear optics of low dimensional electron systems, the optical responses associated with electrons in quantum wires and dots and the optical characterization of electron tunneling in ultra-small structures. We also had informative presentations on recent developments in the studies of optically active porous silicon and the optical properties of C60 molecules.
