Calcareous Algae and Stromatolites
This volume provides a comprehensive overview of calcareous algae and stromatolites. It contains reviews by leading specialists of major groups, together with accounts of floras through time. It deals with marine and non-marine, benthic and planktic, and modern as well as ancient examples. As the first multi-authored review of the field ever published in English, it is an essential reference text for this complex field. It is designed for both postgraduate researchers and professional scientists who require up-to-date and authoritative information on these long-ranging organisms and fabrics which are of wide evolutionary, environmental and sedimentary significance.
Transacting Functions of Human Retroviruses
The coding domains of simple retrovirus genomes direct the synthesis of virion proteins. Complex retroviral genomes generate in addition to virion proteins regulatory transacting proteins that are translated from multiple spliced messenger RNAs and fulfill important functions in the virus life cycle. All human retroviruses have such complex genomes. The transacting proteins of these pathogens are attractive targets for therapeutic intervention because they are viral specific, are essential for efficient virus replication and may be mediators of viral pathogenicity. In summarizing the current knowledge on the regulatory transacting proteins of human retroviruses this volume makes an important contribution toward the control of virus disease.
Microfacies of Carbonate Rocks
This unparelleled reference synthesizes the methods used in microfacies analysis and details the potential of microfacies in evaluating depositional environments and diagenetic history, and, in particular, the application of microfacies data in the study of carbonate hydrocarbon reservoirs and the provenance of archaeological materials. Nearly 230 instructive plates (30 in color) showing thin-section photographs with detailed explanations form a central part of the content. Helpful teaching-learning aids include detailed captions for hundreds of microphotographs, boxed summaries of technical terms, many case studies, guidelines for the determination and evaluation of microfacies criteria, for enclosed CD with 14000 references, self-testing exercises for recognition and characterization skills, and more
Recent Developments in Carbonate Sedimentology in Central Europe
In the field of sedimentary research, ever increasing emphasis has been put on the investigations of carbonates and carbonate rocks during the past 30 years. It is thus quite natural that in Central Europe - where c1assical carbonate in vestigations have already been carried out 100 years ago - numerous scholars turned to the study of this sediment type. On the occasion of a visiting professorship of G. M. FRIEDMAN at the Labora torium für Sedimentforschung, Heidelberg University, a seminar on "Recent Developments of Carbonate Sedimentology in Central Europe" was held in July 1967. 90 persons involved in carbonate investigations participated, and 35 lectures were held. The present volume co...
Nitric Oxide in the Eye
Nitric oxide (NO) is a simple gas with free radical properties. No one would have imagined a role for such a simple substance in the human body. In 1998, R. E Furchgott, E Murad, and L. J. Ignarro received the Nobel prize for their work on NO. Interestingly, Alfred B. Nobel, who invented dynamite by combining nitro glycerin with other substances, took nitroglycerin for his chest pain without realizing that NO mediates its action. Now, in addition to its vasodilating action, NO is known to possess many fundamental functions that include neurotrans mission, blood pressure control, blood clotting, and immune responses. These diverse functions, conversely, imply that the simple NO molecule may u...
