GeomInt–Mechanical Integrity of Host Rocks by Olaf Kolditz,Uwe-Jens Görke,Heinz Konietzky,Jobst Maßmann,Mathias Nest,Holger Steeb,Frank Wuttke,Thomas Nagel Pdf

This open access book summarizes the results of the collaborative project “GeomInt: Geomechanical integrity of host and barrier rocks - experiment, modeling and analysis of discontinuities” within the Program: Geo Research for Sustainability (GEO: N) of the Federal Ministry of Education and Research (BMBF). The use of geosystems as a source of resources, a storage space, for installing underground municipal or traffic infrastructure has become much more intensive and diverse in recent years. Increasing utilization of the geological environment requires careful analyses of the rock–fluid systems as well as assessments of the feasibility, efficiency and environmental impacts of the technologies under consideration. The establishment of safe, economic and ecological operation of underground geosystems requires a comprehensive understanding of the physical, (geo)chemical and microbiological processes on all relevant time and length scales. This understanding can only be deepened on the basis of intensive laboratory and in-situ experiments in conjunction with reliable studies on the modeling and simulation (numerical experiments) of the corresponding multi-physical/chemical processes. The present work provides a unique handbook for experimentalists, modelers, analysts and even decision makers concerning the characterization of various types of host rocks (salt, clay, crystalline formations) for various geotechnical applications.

GeomInt—Discontinuities in Geosystems From Lab to Field Scale by Olaf Kolditz,Keita Yoshioka,Tuanny Cajuhi,Ralf-Michael Günther,Holger Steeb,Frank Wuttke,Thomas Nagel Pdf

This is an open access book. In view of growing conflicts over strategic georesources, the use of the geological subsurface in the sense of a regional resource is becoming increasingly important. In this context, georeservoirs are playing an important role for the energy transition not only as a source of energy but also as a storage facility and deep geological disposal for energy waste. The success of the energy transition also depends to a large extent on the efficient and safe use of underground resources. This book complements the previous basic book (GeomInt—Integrity of Host Rocks) with a series of application examples in different rock formations, clay, salt, and crystalline. The methodology developed in GeomInt is used, among others, in the Mont Terri underground research laboratory (Opalinus Clay), in the large borehole test in Springen (salt rock) and in the “Reiche Zeche” teaching and research mine (crystalline rock). In addition, new methodological developments are also taken up in experiments and models and embedded in workflows for geotechnical system analyses. The present book summarizes the results of the collaborative project “GeomInt2: Geomechanical integrity of host and barrier rocks - experiment, modeling and analysis of discontinuities” within the program: Geo Research for Sustainability (GEO: N) of the Federal Ministry of Education and Research (BMBF).

Mont Terri Rock Laboratory, 20 Years by Paul Bossart,Alan Geoffrey Milnes Pdf

The international Mont Terri rock laboratory in Switzerland plays a central role in the safety and construction of deep geological nuclear repositories in clay formations. The laboratory has developed and refined a range of new measurement and evaluation methods: it has e.g. advanced the determination of rock parameters using innovative borehole geophysics, improved the methodology for characterizing pore-water and microbial activity in claystones, and greatly improved our understanding of diffusion and retention processes of radionuclides in and through claystones. The methods and insights described in this compendium can also be applied to low-permeability rocks at various sites around the globe, and in other fields of application.

The Last Word by Thomas Nagel Pdf

If there is such a thing as reason, it has to be universal. Reason must reflect objective principles whose validity is independent of our point of view--principles that anyone with enough intelligence ought to be able to recognize as correct. But this generality of reason is what relativists and subjectivists deny in ever-increasing numbers. And such subjectivism is not just an inconsequential intellectual flourish or badge of theoretical chic. It is exploited to deflect argument and to belittle the pretensions of the arguments of others. The continuing spread of this relativistic way of thinking threatens to make public discourse increasingly difficult and to exacerbate the deep divisions of our society. In The Last Word, Thomas Nagel, one of the most influential philosophers writing in English, presents a sustained defense of reason against the attacks of subjectivism, delivering systematic rebuttals of relativistic claims with respect to language, logic, science, and ethics. He shows that the last word in disputes about the objective validity of any form of thought must lie in some unqualified thoughts about how things are--thoughts that we cannot regard from outside as mere psychological dispositions.

Computational Geotechnics by Thomas Nagel,Norbert Böttcher,Uwe-Jens Görke,Olaf Kolditz Pdf

In this book, effective computational methods to facilitate those pivotal simulations using open-source software are introduced and discussed with a special focus on the coupled thermo-mechanical behavior of the rock salt. A cohesive coverage of applying geotechnical modeling to the subsurface storage of hydrogen produced from renewable energy sources is accompanied by specific, reproducible example simulations to provide the reader with direct access to this fascinating and important field. Energy carriers such as natural gas, hydrogen, oil, and even compressed air can be stored in subsurface geological formations such as depleted oil or gas reservoirs, aquifers, and caverns in salt rock. Many challenges have arisen in the design, safety and environmental impact assessment of such systems, not the least of which is that large-scale experimentation is not a feasible option. Therefore, simulation techniques are central to the design and risk assessment of these and similar geotechnical facilities.

OpenGeoSys Tutorial by Agnes Sachse,Erik Nixdorf,Eunseon Jang,Karsten Rink,Thomas Fischer,Beidou Xi,Christof Beyer,Sebastian Bauer,Marc Walther,Yuanyuan Sun,Yonghui Song Pdf

This book explores the application of the open-source software OpenGeoSys (OGS) for hydrological numerical simulations concerning conservative and reactive transport modeling. It provides general information on the hydrological and groundwater flow modeling of a real case study and step-by-step model set-up with OGS, while also highlighting related components such as the OGS Data Explorer. The material is based on unpublished manuals and the results of a collaborative project between China and Germany (SUSTAIN H2O). Though the book is primarily intended for graduate students and applied scientists who deal with hydrological modeling, it also offers a valuable source of information for professional geoscientists wishing to expand their knowledge of the numerical modeling of hydrological processes including nitrate reactive transport modeling. This book is the second in a series that showcases further applications of computational modeling in hydrological science.

Models of Thermochemical Heat Storage by Christoph Lehmann,Olaf Kolditz,Thomas Nagel Pdf

Thermochemical gas-solid reactions, as well as adsorption processes, are currently of significant interest for the design of heat storage systems. This book provides detailed models of these reactions and processes that account for heat and mass transport, chemical and physical reactions, and possible local thermal non-equilibrium. The underlying scientific theory behind the models is explained, laboratory tests are simulated, and methods for high-performance computing are discussed. Applications ranging from seasonal domestic heat storage to diurnally operating systems in concentrating solar power facilities are considered in these models, which are not available through any other sources. Finally, an outlook on future developments highlights emerging technologies.

The Mechanical Behavior of Salt – Understanding of THMC Processes in Salt by Manfred Wallner,Karl-Heinz Lux,Wolfgang Minkley,H. Reginald Hardy, Jr. Pdf

A unique opportunity to review the latest progress in an expanding area of interest: the Mechanical Behaviour of Salt. These Proceedings include over fifty papers and summaries describing the latest findings in ongoing studies from a number of research groups. For the 2007 conference, there was a particular focus on the understanding of thermal, mechanical, hydraulic and chemical coupled processes (THMC). Such processes are of specific interest when considering advanced problems in waste disposal, storage and mining. The book includes a number of themes: - laboratory and in-situ investigations modelling, e.g. derivation of constitutive equations - numerical computations and prediction of long-term behaviour - THMC processes in mining projects, storage and permanent disposal - case studies - geology - mining and storage applications and abandonment The International Conferences on the Mechanical Behaviour of Salt have a long tradition, being initiated in 1981 at The Pennsylvania State University, USA. The present conference, the sixth of the series, took place in Hannover, Germany, in May 2007. The conference brought together mining engineers, researchers, and university professors interested in the mechanical behaviour of salt, mostly from Europe and beyond.

The Feeling of Value by Sharon Rawlette Pdf

Winner of New York University's Dean's Outstanding Dissertation Award This revolutionary treatise starts from one fundamental premise: that our phenomenal consciousness includes direct experience of value. For too long, ethical theorists have looked for value in external states of affairs or reduced value to a projection of the mind onto these same external states of affairs. The result, unsurprisingly, is widespread antirealism about ethics. In this book, Sharon Hewitt Rawlette turns our metaethical gaze inward and dares us to consider that value, rather than being something "out there," is a quality woven into the very fabric of our conscious experience, in a highly objective way. On this view, our experiences of pleasure and pain, joy and sorrow, ecstasy and despair are not signs of value or disvalue. They are instantiations of value and disvalue. When we feel pleasure, we are feeling intrinsic goodness itself. And it is from such feelings, argues Rawlette, that we derive the basic content of our normative concepts-that we understand what it means for something to be intrinsically good or bad. Rawlette thus defends a version of analytic descriptivism. And argues that this view, unlike previous theories of moral realism, has the resources to explain where our concept of intrinsic value comes from and how we know when it objectively applies, as well as why we sometimes make mistakes in applying it. She defends this view against G. E. Moore's Open Question Argument as well as shows how these basic facts about intrinsic value can ground facts about instrumental value and value "all things considered." Ultimately, her view offers us the possibility of a robust metaphysical and epistemological justification for many of our strongest moral convictions.
