Chi possiede il passato? Come si leggono le ossa antiche? E cosa ci dicono sulle nostre origini gli artifatti, il polline e il DNA dell'età glaciale? Usando tecniche sempre più raffinate, gli scienziati riescono a ricostruire gli ambienti del passato profondo e i primi esseri umani che ci vivevano. I lettori di ossa esamina i fatti e i miti sull'arrivo dei primi uomini in Australia; il DNA degli attuali Aborigeni australiani rivela le loro origini; le teorie degli hobbit indonesiani; e chi o cosa ha ucciso i marsupiali giganti dell'Australia. Le scoperte australiane trovano eco nei dibattiti sulla misteriosa fine dei Neanderthal e gettano luce sull'evoluzione umana. Ma, come sempre, gli scienziati sono divisi. I lettori di ossa mette in evidenza un mondo di coloriti personaggi e un dibattito appassionato - e alcune idee veramente bizzarre. Questo libro chiarisce le idee a chi è incuriosito da affermazioni e contro-affermazioni su chi ha fatto cosa, quando a e a chi nel profondo passato della preistoria e spiega in modo lineare la scienza su cui si basano le recenti metodologie investigative. Senza timore di essere controverso, I lettori di ossa è destinato a riscaldare il dibattito sul passato dell'umanità.

Heteromagnetic Microelectronics: Microsystems of Active Type, by Alexander A. Ignatiev of Saratov State University and Alexander V. Lyashenko of JSC Research Institute Tantal in Russia, offers a very detailed and specialized account of the author's research and development of heteromagnetic materials and devices. The book is based on original material from the author's programs of designing heteromagnetic microsystems. Polyvalent, multiple parameter magneto-semiconductor microsystems are described and the book reports on extensive experimental and theoretical results of research in a range of frequencies up to 1000 GHz. For the first time the direction of satisfying criteria, and burst technologies, which can make a subject of discovery, are discussed in great detail. This book is intended for post-graduate students and researchers specializing in the design and application of heteromagnetic materials and devices. Alexander A. Ignatiev is author of Magnetoelectronics of Microwaves and Extremely High Frequencies in Ferrite Films (Springer, 2009).

As technology matures, communication system operation regions shift from mic- wave and millimeter ranges to sub-millimeter ranges. However, device perf- mance at very high frequencies suffers drastically from the material de?ciencies. As a result, engineers and scientists are relentlessly in search for the new types of materials, and composites which will meet the device performance requirements and not present any de?ciencies due to material electrical and magnetic properties. Anisotropic and gyrotropic materials are the class of the materials which are very important in the development high performance microwave devices and new types composite layered structures. As a result, it is a need to understand the wave propagation and radiation characteristics of these materials to be able to realize them in practice. This book is intended to provide engineers and scientists the required skill set to design high frequency devices using anisotropic, and gyrotropic materials by providing them the theoretical background which is blended with the real world engineering application examples. It is the author’s hope that this book will help to ?ll the gap in the area of applied electromagnetics for the design of microwave and millimeter wave devices using new types of materials. Each chapter in the book is designed to give the theory ?rst on the subject and solidify it with application examples given in the last chapter. The application examples for the radiation problems are given at the end of Chap. 5 and Chap. 6 for anisotropic and gyrotropic materials, respectively, after the theory section.
