Book Description
The era of easily acquiring oil and gas is over. Now, to extract these resources, deep vertical and curvilinear, off-shore and ground-based boreholes are drilled in inclement climate conditions and in complex heterogeneous tectonic rocks. Additional novelties have also been assimilated into these technologies by the shale revolution. The techniques and methods of borehole drivage are developing so fast that scientific understanding and substantiation have no time to refine them. Therefore, as a rule, different unpredictable emergency effects and overall failures accompany these procedures. The gravest of these are buckling of the drill strings, their resonant vibrations, their sticking during dragging and twisting, the self-triggering of torsional relaxation vibration, and the self-excitation of forward, backward, and superfast bit whirlings. To analyse these phenomena, this volume elaborates new mathematic models and numerical methods. On the basis of these, a special software was created, which allowed new results concerning the peculiarities of the affected phenomena to be achieved. The book will be of interest to borehole designers and specialists in mechanics and applied mathematics.

Book Description
This book - comprised of three separate volumes - presents the recent developments and research discoveries in structural and solid mechanics; it is dedicated to Professor Isaac Elishakoff. This first volume is devoted to the statics and stability of solid and structural members. Modern Trends in Structural and Solid Mechanics 1 has broad scope, covering topics such as: buckling of discrete systems (elastic chains, lattices with short and long range interactions, and discrete arches), buckling of continuous structural elements including beams, arches and plates, static investigation of composite plates, exact solutions of plate problems, elastic and inelastic buckling, dynamic buckling under impulsive loading, buckling and post-buckling investigations, buckling of conservative and non-conservative systems and buckling of micro and macro-systems. This book is intended for graduate students and researchers in the field of theoretical and applied mechanics.

Book Description
This book is one out of six IAEG XIII Congress and AEG 61st Annual Meeting proceeding volumes, and deals with topics related to geologic hazards, such as earthquakes, land subsidence, coastal hazards, and the emergency response. The theme of the IAEG/AEG Meeting, held in San Francisco from September 17-21, 2018, is Engineering Geology for a Sustainable World. The meeting proceedings analyze the dynamic role of engineering geology in our changing world. The meeting topics and subject areas of the six volumes are: Slope Stability: Case Histories, Landslide Mapping, Emerging Technologies; Geotechnical and Environmental Site Characterization; Mining, Aggregates, Karst; Dams, Tunnels, Groundwater Resources, Climate Change; Geologic Hazards: Earthquakes, Land Subsidence, Coastal Hazards, and Emergency Response; and Advances in Engineering Geology: Education, Soil and Rock Properties, Modeling.

Book Description
Water Wells and Boreholes provides the necessary scientificbackground together with practical advice using global casestudies, in an accessible easy to use style suitable for bothpostgraduates/researchers and practitioners. The book begins with an introduction to the type and uses ofwater wells from water supply and irrigation through to groundwaterremediation. It then covers well siting detailing how to sourcedata from geophysical surveys, remote sensing etc. Well design isthen summarised to ensure the well is stable and cost-effective.The book ends with three chapters covering well construction, welltesting and well performance, maintenance and rehabilitation.
