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.

Download or read book The Cosmic Dust Connection written by J. Mayo Greenberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid particles are followed from their creation through their evolution in the Galaxy to their participation in the formation of solar systems like our own, these being now clearly deduced from observations by the Hubble Space Telescope as well as by IR and visual observations of protostellar disks, like that of the famous Beta Pictoris object. The most recent observational, laboratory and theoretical methods are examined in detail. In our own solar system, studies of meteorites, comets and comet dust reveal many features that follow directly from the interstellar dust from which they formed. The properties of interstellar dust provide possible keys to its origin in comets and asteroids and its ultimate origin in the early solar system. But this is a continuing story: what happens to the solid particles in space after they emerge from stellar sources has important scientific consequences since it ultimately bears on our own origins - the origins of solar systems and, especially, of our own earth and life in the universe.
Download or read book Experiments on Cosmic Dust Analogues written by E. Bussoletti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrophysical analysis relating to solid matter requires data on properties and processes. Such data, however, expecially appropriate to space conditions are mostly lacking. It appeared then very tempting to gather together experimentalists, ob servers and theoreticians working in the field of cosmic dust and in related areas. The Workshop held in Capri (Italy) from September 8th till 12th 1987 gave the participants a unique opportunity for exchange of ideas and discussions of problems and experimental procedures. Introductory reports were prepared with the aim of giving the state of the art about single subjects; contributed poster papers presented, on the contrary, very recent results in the various fields. According to his specific interest each attendant has also contributed to three Working Groups respectively on a) carbon, b) silicates, c) ice and related topics. Scientifical and technical problems about these items were discussed in great detail. Though no definite answers were given, useful indications come out which will be of some help for future works. In addition to the scientific efforts, the Capodimonte Observatory and the Istituto Universitario Navale sought to give a warm welcome to the participants. Thanks to several sponsors, the LOC could organize some excursions and shows to entertain people during their spare time.

This book was released on 2013-04-17 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE EDITORS: DAVID L. BLOCK AND KENNETH C. FREEMAN (SOC CO-CHAIRS), IVANIO PUERARI, ROBERT GROESS AND LIZ K. BLOCK 1. Harvard College Observatory, 1958 The past century has truly brought about an explosive period of growth and discovery for the physical sciences as a whole, and for astronomy in particular. Galaxy morphology has reached a renaissance . . The year: 1958. The date: October 1. The venue: Harvard College Observatory. The lecturer: Walter Baade. With amazing foresight, Baade penned these words: "Young stars, supergiants and so on, make a terrific splash - lots of light. The total mass of these can be very small compared to the total mass of the system". Dr Layzer then asked the key question: " . . . the discussion raises the point of what this classification would look like if you were to ignore completely all the Population I, and just focus attention on the Population II . . . " We stand on the shoulders of giants. The great observer E. E. Barnard, in his pioneering efforts to photograph the Milky Way, devoted the major part of his life to identifying and numbering dusty "holes" and dust lanes in our Milky Way. No one could have dreamt that the pervasiveness of these cosmic dust masks (not only in our Galaxy but also in galaxies at high redshift) is so great, that their "penetration" is truly one of the pioneering challenges from both space-borne telescopes and from the ground.

Download or read book The Chemistry of Cosmic Dust written by David A Williams and published by Royal Society of Chemistry. This book was released on 2015-11-18 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been firmly established over the last quarter century that cosmic dust plays important roles in astrochemistry. The consequences of these roles affect the formation of planets, stars and even galaxies. Cosmic dust has been a controversial topic but there is now a considerable measure of agreement as to its nature and roles in astronomy, and its initiation of astrobiology. The subject has stimulated an enormous research effort, with researchers in many countries now involved in laboratory research and in ab initio computations. This is the first book devoted to a study of the chemistry of cosmic dust, presenting current thinking on the subject distilled from many publications in surface and solid-state science, and in astronomy. The authors discuss the nature of dust, its formation and evolution, the chemistry it can promote on its surfaces, and the consequences of these functions. The purpose of this book is to review current understanding and to indicate where future work is required. Mainly intended for researchers in the field of astrochemistry, the book could also be used as the basis of a course for postgraduate students who have an interest in astrochemistry.
Download or read book Cosmic Dust Collection Facility Scientific Objectives and Programmatic Relations written by and published by . This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science objectives are summarized for the Cosmic Dust Collection Facility (CDCF) on Space Station Freedom and these objectives are related to ongoing science programs and mission planning within NASA. The purpose is to illustrate the potential of the CDCF project within the broad context of early solar system sciences that emphasize the study of primitive objects in state-of-the-art analytical and experimental laboratories on Earth. Current knowledge about the sources of cosmic dust and their associated orbital dynamics is examined, and the results are reviewed of modern microanalytical investigations of extraterrestrial dust particles collected on Earth. Major areas of scientific inquiry and uncertainty are identified and it is shown how CDCF will contribute to their solution. General facility and instrument concepts that need to be pursued are introduced, and the major development tasks that are needed to attain the scientific objectives of the CDCF project are identified.
Download or read book Dust in the Solar System and Other Planetary Systems written by S.F. Green and published by Elsevier. This book was released on 2002-12-10 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the last joint IAU and COSPAR Colloquium in Gainesville in 1995, there have been dramatic changes in the field resulting from in-situ space experiments, Earth orbiting satellites and ground based observations. The brightest comet since the early years of the twentieth century, comet Hale-Bopp, appeared, giving an invaluable opportunity to see in action one great source of interplanetary dust. Similarly, the Leonid meteor shower has been at its most active since 1966, producing spectacular displays of meteors and allowing for an array of observational techniques, not available in 1966 to be used, while theory has also been refined to a level where very accurate predictions of the timing of meteor storms has become possible. Prior to the meeting a total eclipse of the Sun in South West England and North Europe was observed, traditionally a good opportunity to observe the Zodiacal cloud. The knowledge of the Near-Earth Asteroid population has also increased dramatically, with the increased study arising from the heightened awareness of the danger to Earth from such bodies. Extrasolar planets have been discovered since the last meeting and it is recognised that interplanetary dust in other Planetary Systems can now be studied. Since much of the dust observed in such systems is at a distance of order 100 AU from the star, this brings into focus the production of dust in the Edgeworth-Kuiper belt of our own system. Recent years have seen a recognition of the importance of dust originating outside our own system, that is now present in the near-Earth environment. As is always the case when great strides take place observationally, much theoretical work follows, and the same is true in this instance. While data about the planetary medium from Venus to Jupiter was beginning to be available at the meeting in 1995, the data from both Galileo and Ulysses have now been more fully analysed, with a corresponding increase in our knowledge. This book reflects the thematic approach adopted at the meeting, with a flow outwards (from meteors in the atmosphere, through zodiacal dust observation and interplanetary dust, to extra solar planetary systems) and returning (via the Edgeworth-Kuiper belt and comets) to the Earth, with laboratory studies of physical and chemical processes and the study of extra-terrestrial samples.

Download or read book Dust and Chemistry in Astronomy written by T.J Millar and published by Routledge. This book was released on 2019-06-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dust is widespread in the galaxy. To astronomers studying stars it may be just an irritating fog, but it is becoming widely recognized that cosmic dust plays an active role in astrochemistry. Without dust, the galaxy would have evolved differently, and planetary systems like ours would not have occurred. To explore and consolidate this active area of research, Dust and Chemistry in Astronomy covers the role of dust in the formation of molecules in the interstellar medium, with the exception of dust in the solar system. Each chapter provides thorough coverage of our understanding of interstellar dust, particularly its interaction with interstellar gas. Aimed at postgraduate researchers, the book also serves as a thorough review of this significant area of astrophysics for practicing astronomers and graduate students.
