The U.S. Bureau of Mines examined previous research on rib stability in an effort to develop a practical approach to understanding, characterizing, and controlling weak rib conditions in underground coal mines. Because success in stabilizing ribs depends on a basic knowledge of how weak ribs behave, the report reviews the mechanics of rib failure and the relationship of coal mine geology and pillar constraint to rib instability. Strategies for choosing an effective method of rib support are considered, and various rib support methods are discussed. Finally, the report documents techniques for monitoring ribs and use of models to assess rib stability; such monitoring and modeling can also help determine the most effective method for roof support.

First built in the 1960s for rescue work, the Rigid Inflatable Boat has revolutionised the marine market. The Complete RIB Manual, published to coincide with the 50th anniversary of the first RIB, is the ultimate reference catering all aspects of a RIB's design, handling and maintenance, aimed at all owners and users, both commercial and leisure. The emphasis of the book is entirely practical, and covers: 1. A History of the RIB • Early development • Modern design: leisure, commercial and military 2. RIB Handling • Impact of hull design, tube types, internal layout and engines • Driving techniques: throttle control and driving position • Advanced techniques for economy, sport and rough seas • Cruising: planning, weather, anchoring and communications • RIBs as tenders - stowing and towing • Launching and transportation • Safety and survival 3. Maintenance • Outboards, diesels, water jets, stern drives, fuel tanks and electrics • Tube care: cleaning, repair, replacement • Hull maintenance • Winter storage, checking for leaks, servicing The Complete RIB Manual is a comprehensive worldwide reference for all RIB owners and users, covering all the information necessary to handle and maintain a RIB of any size.

Over the past two decades there have been major advances in the treatment of spinal disorders including anterior decompression of the neural structures as well as various forms of spinal stabilization by utilization of implants. These changes primarily reflect the development of better techniques of diagnosis and anesthesia, as well as new fusion procedures that are often supplemented with instrumentation. Biomechanics of Spine Stabilization bridges the gap that has existed between the physics of biomechanical research and the clinical arena. The book helps surgeons to plan treatments for the injured spine based on sound biomechanical principles - principles that will influence the surgeon's choice for the surgical approach, type of fusion and type of instrumentation. Biomechanics of Spine Stabilization begins with the essentials, proceeds gradually toward the development of an understanding of biomechanical principles, and, finally, provides a basis for clinical decision-making. These features make it a cover-to-cover must-read for anyone who is involved with the care of a patient with an unstable spine. Chocked full of illustrations, Biomechanics of Spine Stabilization includes: -Physical principles and kinematics -Segmental motion, stability and instability -Spine and neural element pathology -Surgical approaches and spinal fusion -Spinal instrumentation: General principles -Spinal instrumentation constructs: biomechanical attributes and clinical applications -Non-operative spinal stabilization -Special concepts and concerns -CD-ROM containing illustrations from book to create mental images of critical anatomical, biomechanical and clinical points

Up-to-date and multidisciplinary, this text brings together all of the latest research and clinical treatment strategies for the management of injuries to the chest wall and rib cage. The management of trauma to the chest wall, especially “flail chest” injuries, has been relatively stagnant for many years. Non-operative treatment has been the standard of care, and despite some advances, has reached the point where there is little new to offer a severely traumatized patient. However, recently, there has been a dramatic increase in the interest in surgical fixation of unstable chest wall injuries. Specifically, plate or intramedullary nail fixation of multiple rib fractures has rapidly become the state-of-the-art in many trauma centers, and there have multiple research papers, reviews, new fixation devices, and instructional courses at national level meetings on this topic. This book assembles a diverse group of experts in the field—orthopedic surgeons, trauma surgeons, anesthetists, basic science researchers—to produce the definitive work on this topic that will appeal to a wide variety of medical practitioners.

Under the Monitoring of Completed Coastal Projects (MCCP) work unit, Periodic Inspections, past MCCP structures and structures with unique design aspects that have probable applications to other projects are considered for inclusion in a periodic monitoring program. The emphasis of the work is to measure the long-term response of the above-water portions of the structures to their environment. The rubble-mound breakwaters at Kahului Harbor, Maui, Hawaii, and Laupahoehoe Boat Launching Facility, Laupahoehoe Point, Hawaii, Hawaii, are armored with concrete armor unit and concrete rib caps. By means of limited land surveys, low-level helicopter inspections with 35-mm photography, aerial photography, and photogrammetric analysis base conditions have been established for the breakwaters. Now that the base (control) conditions have been defined and a method has been developed to closely compare subsequent years of high- resolution aerial photography of the Kahului and Laupahoehoe breakwaters, these sites will be revisited during future years to gather data by which assessments can be made on the long-term response of the structures to their environment. Insight gathered from these efforts will allow definite decisions to be made based on sound data as to whether or not closer surveillance and/or repair of a structure is required to reduce the chance that it will fail catastrophically.
