General Relativity and the Pioneers Anomaly


Free Download Marcelo Samuel Berman, "General Relativity and the Pioneers Anomaly "
English | ISBN: 1621000036 | 2012 | 205 pages | PDF | 6 MB
This book is an introduction to the General Relativity Theory (GRT) and to the solution of the Pioneers Anomaly by means of relativistic cosmology, a study that is designed to be understood by undergraduate and graduate students alike in the fields of theoretical physics, applied mathematics and space engineering. In fact, this book is the first elementary account of GRT and cosmology to address the NASA problem, which consists of a specific deceleration suffered by two space-probes launched to outer space more than thirty years ago. The other two NASA anomalies, which are, the spin-down of the Pioneers, when they were not disturbed, and the fly-by of spacecraft in gravity assists, around the Earth, are explained by Berman, along with the linear deceleration, by the rotation of the Universe, and General Relativity theory.

Arachidonic Acid Dietary Sources and General Functions


Free Download Gerard G. Dumancas, "Arachidonic Acid: Dietary Sources and General Functions "
English | ISBN: 1622574818 | 2012 | 255 pages | PDF | 6 MB
Arachidonic acid (AA) is an -6 polyunsaturated fatty acid found in the phospholipids of the membranes of the human body’s cells, and is abundant in the brain, muscles, and liver. This fatty acid is particularly obtained from meat products including chicken, beef, pork, and fishes. An interesting source of AA is through its accumulation in a green microalga, Myrmecia incisa, enhanced by nitrogen starvation. The general functions of AA and its metabolites including its association with coronary heart disease, oxidative stress and cancer, metabolic syndrome, insulin resistance, and its endocrine response to stress are also discussed.

With more than 10,000 known species, recent reptiles (excluding birds) are the most specious tetrapod class. Their diversity is high, and many of them are frequently used as model organisms in phylogeographic and ecological studies. On the other hand, unique aspects of their biology are still being studied and important contributions to their understanding have just been issued. These aspects include the evolution of viviparity and of venom glands, metabolic regulation in poikilotherms, their ecophysiological tolerance and neurobiological and sensorial capacities such as infrared imaging and chemosensitivity. Genetic and developmental phenomena such as parthenogenesis and temperature-dependent sex determination are also special to reptiles. They are generally important for understanding evolutionary processes in vertebrates.

Towards a General Theory of Classifications


Free Download Towards a General Theory of Classifications By Daniel Parrochia, Pierre Neuville (auth.)
2013 | 304 Pages | ISBN: 3034806086 | PDF | 4 MB
This book is an essay on the epistemology of classifications. Its main purpose is not to provide an exposition of an actual mathematical theory of classifications, that is, a general theory which would be available to any kind of them: hierarchical or non-hierarchical, ordinary or fuzzy, overlapping or non-overlapping, finite or infinite, and so on, establishing a basis for all possible divisions of the real world. For the moment, such a theory remains nothing but a dream. Instead, the authors essentially put forward a number of key questions. Their aim is rather to reveal the "state of art" of this dynamic field and the philosophy one may eventually adopt to go further. To this end they present some advances made in the course of the last century, discuss a few tricky problems that remain to be solved, and show the avenues open to those who no longer wish to stay on the wrong track. Researchers and professionals interested in the epistemology and philosophy of science, library science, logic and set theory, order theory or cluster analysis will find this book a comprehensive, original and progressive introduction to the main questions in this field.

SYMMETRIES AND CURVATURE STRUCTURE IN GENERAL RELATIVITY


Free Download G. S. Hall, "SYMMETRIES AND CURVATURE STRUCTURE IN GENERAL RELATIVITY "
English | ISBN: 9810210515 | 2004 | 440 pages | PDF | 20 MB
Hall (U. of Aberdeen) compiles the theoretical aspects of the literature on symmetries in general relativity that have been produced over the past few decades. He is not offering a textbook, he warns, but a study of certain aspects of four-dimensional Lorentzian differential geometry emphasizing the special requirements of Einstein’s general theory of relativity. His main goal is to present a mathematical approach to symmetries and to the related topic of the connection and curvature structure of space-time, without paying much attention to attendant problems that worry mathematicians more than physicists.

Topics in the Foundations of General Relativity and Newtonian Gravitation Theory


Free Download David B. Malament, "Topics in the Foundations of General Relativity and Newtonian Gravitation Theory "
English | ISBN: 0226502457 | 2012 | 368 pages | PDF | 2 MB
In Topics in the Foundations of General Relativity and Newtonian Gravitation Theory, David B. Malament presents the basic logical-mathematical structure of general relativity and considers a number of special topics concerning the foundations of general relativity and its relation to Newtonian gravitation theory. These special topics include the geometrized formulation of Newtonian theory (also known as Newton-Cartan theory), the concept of rotation in general relativity, and Gödel spacetime. One of the highlights of the book is a no-go theorem that can be understood to show that there is no criterion of orbital rotation in general relativity that fully answers to our classical intuitions. Topics is intended for both students and researchers in mathematical physics and philosophy of science.
