Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Chimaeroid Fishes and Their Development Chimaeroid fishes, a group representing some of the oldest and simplest of backboned animals, arc considered in the present memoir with especial regard to their relationship and descent. To this end, attention has now been paid to the plan of their embryonic development, and upon this side evidence has been obtained which, whether of major or minor importance in the study of descent, has at least the interest of newness. For to the embryologist Chimacroids have until recently remained practically unknown, and they are thus the only vertebrate group of their anatomical importance-if ranked as a subclass-to have escaped investigation. On the other hand, from the standpoints of comparative anatomy and paleontology these shark-like fishes have received considerable notice, and they have figured in publications of the past half-century as the "most primitive vertebrates," or, more precisely, as the least modified descendants of the ancestral cranium- and jaw-bearing vertebrate. And in such a role (which I now believe is only partially deserved) they have been given especial importance in problems of descent. The evidence which has been brought forward to demonstrate the primitive nature of Chima roids is based in part upon the findings of paleontology; it is, moreover, as one frankly admits, supported by anatomical facts which are broad in range and which have in many instances been provided by masters in morphology. The substance of this evidence is that Chimacroids, although shark-like, are nevertheless widely distinct from the shark, and that they represent a lower plane in piscine evolution. As an aid to subsequent reference, the grounds for this conclusion may now be summarized. Chimaroids are believed by some to be older than sharks. Their fossils, as Walcott maintains, occur among fragments of "fish" plates in the Ordovician (Lower Silurian) sandstones. Sharks, on the other hand, do not occur-that is, unquestionably-before the Upper Silurian. Probable it is that Chimacroids lived during the Lower Devonian and, judging from their dental plates, these forms, if Chimaeroid, were highly differentiated, even at this early period. Moreover, according to the studies of Jaekcl, paleozoic Chimacroids provide the evolutional stages from certain archaic armored "fishes" to the shagreencd sharks.

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.

Book excerpt: NATIONAL BESTSELLER • "A dazzling journey across the sciences and humanities in search of deep laws to unite them." —The Wall Street Journal One of our greatest scientists—and the winner of two Pulitzer Prizes for On Human Nature and The Ants—gives us a work of visionary importance that may be the crowning achievement of his career. In Consilience (a word that originally meant "jumping together"), Edward O. Wilson renews the Enlightenment's search for a unified theory of knowledge in disciplines that range from physics to biology, the social sciences and the humanities. Using the natural sciences as his model, Wilson forges dramatic links between fields. He explores the chemistry of the mind and the genetic bases of culture. He postulates the biological principles underlying works of art from cave-drawings to Lolita. Presenting the latest findings in prose of wonderful clarity and oratorical eloquence, and synthesizing it into a dazzling whole, Consilience is science in the path-clearing traditions of Newton, Einstein, and Richard Feynman.
Download or read book Fingerprint Development Techniques written by Stephen M. Bleay and published by John Wiley & Sons. This book was released on 2018-02-16 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of the latest fingerprint development and imaging techniques With contributions from leading experts in the field, Fingerprint Development Techniques offers a comprehensive review of the key techniques used in the development and imaging of fingerprints. It includes a review of the properties of fingerprints, the surfaces that fingerprints are deposited on, and the interactions that can occur between fingerprints, surfaces and environments. Comprehensive in scope, the text explores the history of each process, the theory behind the way fingerprints are either developed or imaged, and information about the role of each of the chemical constituents in recommended formulations. The authors explain the methodology employed for carrying out comparisons of effectiveness of various development techniques that clearly demonstrate how to select the most effective approaches. The text also explores how techniques can be used in sequence and with techniques for recovering other forms of forensic evidence. In addition, the book offers a guide for the selection of fingerprint development techniques and includes information on the influence of surface contamination and exposure conditions. This important resource: Provides clear methodologies for conducting comparisons of fingerprint development technique effectiveness Contains in-depth assessment of fingerprint constituents and how they are utilized by development and imaging processes Includes background information on fingerprint chemistry Offers a comprehensive history, the theory, and the applications for a broader range of processes, including the roles of each constituent in reagent formulations Fingerprint Development Techniques offers a comprehensive guide to fingerprint development and imaging, building on much of the previously unpublished research of the Home Office Centre for Applied Science and Technology.

Download or read book Phytochemical Methods written by Jeffrey B. Harborne and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.
