This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: DANS LE BUT DE MIEUX COMPRENDRE LES PROCESSUS PHOTOGRAPHIQUES, NOUS AVONS ETUDIE, PAR SPECTROMETRIES D'EMISSION ET DE DIFFUSION RAMAN A TRES BASSE TEMPERATURE (8 K), DES MACROCRISTAUX ET DES MICROCRISTAUX DE BROMURE D'ARGENT, DOPES OU NON. LES TRAVAUX EFFECTUES SUR LES MACROCRISTAUX NOUS ONT PERMIS DE LOCALISER, DANS LA BANDE INTERDITE DU BROMURE D'ARGENT, LES NIVEAUX DE PIEGES A ELECTRONS ET DE PIEGES A TROUS. CES NIVEAUX SONT DUS A DES IMPURETES EXTRINSEQUES (PIEGES A ELECTRONS OU A TROUS), DES DEFAUTS INTRINSEQUES (ION ARGENT INTERSTICIEL, PIEGE A ELECTRONSET VACANCE D'ARGENT, PIEGE A TROUS) OU A DES AGREGATS D'ARGENT DE DEUX OU TROIS ATOMES (PIEGES A ELECTRONS). SUR LES MICROCRISTAUX PURS, LE MEME SPECTRE RAMAN EST TOUJOURS OBTENU APRES IRRADIATION, A TEMPERATURE AMBIANTE, AVEC UN FAISCEAU LASER. CE SPECTRE SEMBLE ETRE CARACTERISTIQUE D'UNE DISTRIBUTION D'AGREGATS DONT LES TAILLES SONT COMPRISES ENTRE DEUX ET CINQ ATOMES D'ARGENT. L'ETUDE DES MICROCRISTAUX DOPES NOUS A CONDUIT A PROPOSER DES ENERGIES DE LOCALISATION POUR LES PIEGES A ELECTRONS DANS LE CAS D'UNE SENSIBILISATION AU SOUFRE SEUL OU ASSOCIE A L'OR. LA SENSIBILISATION SERAIT DUE A L'APPROFONDISSEMENT DES NIVEAUX DE CES PIEGES. LES ATOMES DE SOUFRE OU D'OR NE SONT, EN EFFET, PAS INCORPORES DANS LES AGREGATS FORMES LORS DES IRRADIATIONS
Download or read book Infrared Spectroscopy in Conservation Science written by Michele R. Derrick and published by Getty Publications. This book was released on 2000-03-16 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides practical information on the use of infrared (IR) spectroscopy for the analysis of materials found in cultural objects. Designed for scientists and students in the fields of archaeology, art conservation, microscopy, forensics, chemistry, and optics, the book discusses techniques for examining the microscopic amounts of complex, aged components in objects such as paintings, sculptures, and archaeological fragments. Chapters include the history of infrared spectroscopy, the basic parameters of infrared absorption theory, IR instrumentation, analysis methods, sample collection and preparation, and spectra interpretation. The authors cite several case studies, such as examinations of Chumash Indian paints and the Dead Sea Scrolls. The Institute’s Tools for Conservation series provides practical scientific procedures and methodologies for the practice of conservation. The series is specifically directed to conservation scientists, conservators, and technical experts in related fields.

Download or read book Cave and Karst Systems of Romania written by Gheorghe M. L. Ponta and published by Springer. This book was released on 2018-07-04 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on Romania’s more than 12,000 caves, which developed in limestone (including thermal water caves), salt, gypsum, and occasionally in sandstone. It examines these caves and related topics in a format suitable for cavers, while also addressing a broad range of aspects useful for students and researchers. Since the Institute of Speleology was first established by Emil Racovita in 1920, a great deal of research has been conducted on all cave and karst types. As such, the book examines a variety of scientific fields, including karst geology, hydrogeology, biospeleology, paleoclimatology, mineralogy and archaeology.

Download or read book Organic Chemistry of Museum Objects written by John Mills and published by Routledge. This book was released on 2012-09-10 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The Organic Chemistry of Museum Objects' makes available in a single volume, a survey of the chemical composition, properties and analysis of the whole range of organic materials incorporated into objects and artworks found in museum collections. The authors cover the fundamental chemistry of the bulk materials such as wood, paper, natural fibres and skin products, as well as that of the relatively minor components incorporated as paint, media, varnishes, adhesives and dyes. This expanded second edition, now in paperback, follows the structure of the first, though it has been extensively updated. In addition to chapters on basic organic chemistry, analytical methods, analytical findings and fundamental aspects of deterioration, the subject matter is grouped as far as possible by broad chemical class - oils and fats, waxes, bitumens, carbohydrates, proteins, natural resins, dyestuffs and synthetic polymers. This is an essential purchase for all practising and student conservators, restorers, museum scientists, curators and organic chemists.
Download or read book The Fingerprint written by U. S. Department Justice and published by Createspace Independent Publishing Platform. This book was released on 2014-08-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of The Fingerprint Sourcebook originated during a meeting in April 2002. Individuals representing the fingerprint, academic, and scientific communities met in Chicago, Illinois, for a day and a half to discuss the state of fingerprint identification with a view toward the challenges raised by Daubert issues. The meeting was a joint project between the International Association for Identification (IAI) and West Virginia University (WVU). One recommendation that came out of that meeting was a suggestion to create a sourcebook for friction ridge examiners, that is, a single source of researched information regarding the subject. This sourcebook would provide educational, training, and research information for the international scientific community.

This book was released on 1992-02-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Matching DNA samples from crime scenes and suspects is rapidly becoming a key source of evidence for use in our justice system. DNA Technology in Forensic Science offers recommendations for resolving crucial questions that are emerging as DNA typing becomes more widespread. The volume addresses key issues: Quality and reliability in DNA typing, including the introduction of new technologies, problems of standardization, and approaches to certification. DNA typing in the courtroom, including issues of population genetics, levels of understanding among judges and juries, and admissibility. Societal issues, such as privacy of DNA data, storage of samples and data, and the rights of defendants to quality testing technology. Combining this original volume with the new update-The Evaluation of Forensic DNA Evidence-provides the complete, up-to-date picture of this highly important and visible topic. This volume offers important guidance to anyone working with this emerging law enforcement tool: policymakers, specialists in criminal law, forensic scientists, geneticists, researchers, faculty, and students.
