Neogene, Paleontology of the Manonga Valley, Tanzania: A Window into the Evolutionary History of East Africa (Topics in Geobiology)

Book Description

Contributions to this volume detail paleontologic research in Manonga Valley, and shed important light on the evolutionary development of eastern Africa. Chapters provide novel insights into the taxonomy, paleobiology, ecology, and zoogeographic relationships of African faunas, as well as lay the foundation for future geological, paleontological, and paleoecological studies in this important area. The book concludes with a discussion of the importance of investigations on broader geographical sites, including the Manonga Valley, for human evolution research. The text is supported by 143 illustrations.

Book Description

The United States has absorbed nearly 10 million immigrants in the past decade. This book examines who the new immigrants are, where they live, and who among them are gaining entry into the American middle class. Discussed are the complex factors that promote or hinder immigrant success, as well as the varying opportunities and constraints met by those living in particular regions. Extensive data are synthesized on key dimensions of immigrant achievement: income level, professional status, and rates of homeownership and political participation. Also provided is a balanced analysis of the effects of immigration on broader socioeconomic, geographic, and political trends. Examining the extent to which contemporary immigrants are realizing the American dream, this book explores crucial policy questions and challenges that face our diversifying society.

Book Description

This book provides a systematic treatment of the thermal and elastic deformation of bearings, seals, and other machine elements under a wide variety of conditions. In particular, it discusses failure mechanisms in bearings and seals when high speeds or loads cause significant frictional heating and methods for predicting and avoiding such failures. Intended for designers and mechanical engineers responsible for high-performance machinery, the book is unique in giving a systematic treatment of instabilities driven by frictional heating and thermal expansion and in developing a theoretical approach to engineering design in those cases in which the thermal problems are pivotal. It thus provides a guide as to what is important and what is secondary in the development of high-performance engineering systems. References to recent publications, new material that fill gaps in the literature, a consistent nomenclature, and a large number of worked examples make this a useful text and reference for researchers and practicing engineers.

Book Description

This classic work, originally published in 1950, was a landmark in the development of the subject of tribology. When it was first published, one reviewer wrote that it 'marks the beginning of a new epoch in the study of friction and lubrication .... The most interesting and comprehensive work on a single branch of physics I have ever read.' For the 1986 reprint David Tabor wrote a new preface, reviewing developments in the subject in the 36 years since the book first appeared. He has also added an appreciation of the life and work of F.P. Bowden, who died in 1968.

Book Description

Tribology is a science of friction, wear and lubrication of moving components. Advances in tribology have made it possible to considerably reduce energy and material losses in machines and during technological processes. Mechanics of solids, in particular contact mechanics and fracture mechanics, is a powerful tool for investigation of basic tribological problems.
This volume suggests new formulations and methods of solution of contact problems, describing specific features of friction interaction essential for tribology. These problems take into account the discreteness of contact of rough surfaces, surface inhomogeneity, properties of an intermediate medium, complicated boundary conditions, surface fracture, shape variations of surfaces in wear processes, and so on. The solutions of these problems are used to describe the friction and wear processes, to predict their characteristics for given loading and friction conditions, and to determine the optimal parameters of surface treatment for increasing the service life and reliability of moving components. Most solutions presented in the book are expressed in the closed form.
This book will be helpful to engineers and researchers in the field of contact mechanics and tribology. It can be recommended as a supplementary text for graduate and post-graduate students.

Development of a High-Precision Sensor for the Attitude Determination of the Bifocal Spacecraft Simulator

Manufacturer: Storming Media
ProductGroup: Book
Binding: Spiral-bound

Product Description

This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A190524. The abstract provided by the Pentagon follows: The Bifocal Relay Mirror spacecraft attitude control simulator is under development in the Spacecraft Research and Design Center of the Naval Postgraduate School (NPS). The objective of this test bed is to provide on-the- ground simulation of the dynamics and control of spacecraft for high precision acquisition, tracking, and pointing applications associated with space-based laser relay. The required initial attitude determination accuracy for the Bifocal Relay Mirror test bed is 10 micron-radians. Normally, in laboratories where very high initial attitude knowledge is required, actual (space qualified) star trackers are incorporated into the test bed design. This is not possible at NPS as the laboratory does not have a skylight to allow visual access to the stars, and the photosensitive nature of many of the experiments would make such an opening inconvenient. Since it is critical to the operation of the test bed to provide accurate attitude knowledge, a substitute system was required. The present thesis documents the development of a new attitude sensor capable of providing attitude information within the required 10 micron-radians (within a field of view of the order of 1 degree). The concepts leading up to the final design, the testing and selection of the equipment used in the final configuration, and a detailed explanation of how the final system calibration was performed are discussed in detail in this paper.

Book Description

1835. Written by a Rosicrucian adept, this fantastic tale is a masterful work of occult teachings. Not written for the masses, Seraphita was for those few lofty spirits who could discern Jacobs mystical stair.

Customer Reviews:

unforgettable portrait of spiritual attainment.......2006-04-26

One of the very greatest achievements of European literature. A pair of lovers transcend every conceivable spiritual obstacle to transcend their very sexual identities, becoming one with one another in the most refined and lofty circumstances imaginable. And you believe it, if you are ready. Balzac's and the reader's Mt. Everest, equaled but not surpassed by Holderlin's HYPERION and other great contemporaneous works of German romanticism.

Swedenborgian aesthetics.......2000-04-04

The opening of this book is one of the most sublime and lovely scenes in French literature. It is the description of an ascent up a Norwegian fjord by a girl and an other-worldy being,and, as Gautier said, "He has used no colors but the pure blue of the sky, the white of the snow, and a few pearly tints for the shadows."

The rest of the book involves long didactic sermons, but as the sermons pertain to Swedenborgian theology, they are aestheitcally gratifying as well as instructive.

Amateurs may be confused by the character of Seraphita/Seraphitus, who continually fluctuates between both genders, and some may fail to see how this all relates to the Human Comedy, but I think most readers will be entirely capable of enjoying and comprehending this wonderful novel.
