Mankind constructed many structures in/on rocks in association with better living conditions and expectations of their societies. Without any doubt, these activities would continue in modern days and the future. Such activities may be extended to other planets in our solar system. The rock mechanics and rock engineering feld utilizes some of the basic laws of continuum mechanics and the techniques developed in computational mechanics. This book is intended to describe the basic concepts behind these fundamental laws and their utilization in practice irrespective of whether rock and rock mass contain discontinuities. <...>

A. Allgemeiner Teil Einführung in die Forschungsrichtung der Sedimentologie und Vorstellung des Studienobjektes
Nachstehende allgemeinverständliche Einleitung für einen breiten Leserkreis gibt einen Überblick über die Stellung der Sedimentologie in der Geologie und die Arbeitsrichtungen dieses Wissenschaftszweiges, stellt den Buntsandstein als Beispielsobjekt sedimentologischer Forschung vor und definiert die Zielsetzung des Buches.

This article and a future article in the SEG Newsletter will serve as previews to an SEG-sponsored forum to examine and discuss the origins of gold deposits in the Carlin and Witwatersrand camps. The forum will be held in Reno, Nevada, on May 14, 2005, in conjunction with Geological Society of Nevada’s Symposium 2005 – Window to the World. Both districts have been the focus of major controversies. In this article, three short papers discuss the origin of Carlin-type deposits in north-central Nevada. Over the last few decades, Carlin-type deposits have been seen as shallow hot spring deposits, distal products of porphyry copper deposits, and the uppermost parts of deep mesother-mal systems. The first paper, by Jean Cline, provides an introduction to the characteristics of Carlin-type deposits and a framework for discussions of their origin. The second paper, by Marcus Johnston and Michael Ressel, argues for a magmatic origin for the deposits, and specifically that plutons are the source of heat and probably fluids and metals. The third paper, by Eric Seedorff and Mark Barton, discusses amagmatic models for the origin of Carlin-type deposits, as well as pointing out shortcomings in magmatic models. These authors will give talks at the May 2005 forum, which will be followed by panel and open discussions with the aim of identifying what we need to know to better understand and explore for these deposits.

During the past few years many experiments have been tried in the development of Manual Training Courses and much time has been spent in discussing of what lines of work they should consist. Wood and iron were the first materials used and are yet indispensable, but experience has led those who are developing this work to believe that there are other materials as well adapted to Manual Train¬ ing work in all its various forms. Clay, used not only for modeling but for ceramic work as well, leather, brass and copper are materials that have also been put to the test and found satisfactory in many ways
