Nondestructive Testing involves the use of methods such as wave propagation, electromagnetism, electrical conductivity, and thermal conductivity to test structural integrity and thereby allow nondestructive assessment of structures and the possibility of structural failures before they occur. Nondestructive Testing of Deep Foundations covers different techniques designed to provide information about the integrity and quality of the material that makes up a deep foundation. Nondestructive Testing methods are used at all stages of a structure's life - from new construction quality control to residual lifetime prediction, and even during the monitoring of demolition. In addition, Nondestructive Testing is being increasingly specified in deep foundation projects, though often without a good understanding of its limitations and with the result that methods are often misused. In order to be able to specify an appropriate method, or to recognize an inappropriate specification, it is necessary for the engineer, specifier and/or contractor to understand the capabilities and limitations of each of the methods currently in use. Nondestructive Testing of Deep Foundations: Describes the most commonly used deep foundation construction techniques, including typical use of material Provides a brief history of the development of commercially available nondestructive methods Summarises each method's capabilities and limitations Acts as a one stop reference drawing together resources only previously available in conference proceedings and journal papers This manual will prove to be a welcome addition to the bookshelf of all practitioners in civil/structural and geotechnical engineering and architecture. It will also provide a valuable insight into this highly technical field for university researchers, lecturers and postgraduate students in civil/structural and geotechnical engineering.
Land development to support population increases and shifts requires changes to the hydrologic cycle. Increased impervious area results in greater volumes of runoff, higher flow velocities, and increased pollutant fluxes to local waterways. As we learn more about the negative impacts of these outcomes, it becomes more important to develop and manage land in a smart manner that reduces these impacts. This text provides the reader with background information on hydrology and water quality issues that are necessary to understand many of the environmental problems associated with land development and growth. The variability of runoff" flows and pollutant concentrations, however, makes the performance of simple technologies erratic and predicting and modeling their performance difficult. Chapters on statistics and modeling are included to provide the proper background and tools. The latter chapters of the text cover many of the different technologies that can be employed to address runoff flows and improve water quality. These chapters take a design approach with specific examples provided for many of the management practices. A number of methods are currently available for addressing the problems associated with stormwater runoff quality from urban areas; more continue to be developed as research is advanced and interest in this subject continues to surge. Traditionally, techniques for the improvement of runoff quality were borrowed applications from water and wastewater treatment, such as large sedimentation ponds Recently, increased interest has been placed on using natural systems to improve water quality.
This manual helps clinicians easily to find the best available evidence to facilitate sound medical decisions. It is the first published compilation of highly relevant InfoPOEMs that the editors believe has the potential to change a clinician's practice. The editors have selected over 300 of the most influential, compelling POEMs, and organized them by topic for easy reference. Each POEM contains: Clinical Question: Poses a question that the study seeks to answer. Bottom line: Summarizes the findings of the research and places these findings into the context with the known information on the topic. The bottom line also is designed to help readers understand how to apply the results. LOE: Each review is given a Level of Evidence indicator. This allows the reader to discern an overall sense of how well the new information is supported. Reference: Displays the citation of the article being reviewed. Study Design: Identifies the procedures of the study (i.e., Meta-Analysis, randomized controlled trial). Setting: Identifies the environment in which the study took place (i.e., outpatient, inpatient). Synopsis: Provides a brief overview of the study design and results, but is not an abstract. The editors have pulled out only the most important information - the materials that readers need to judge the validity of the research and to understand the results. The manual opens with two complementary, original chapters: 1) Introduction to Information Mastery which covers the skills physicians need to practice the best medicine. 2) An Introduction to Evidence Based Medicine that reviews the key concepts and principles behind this practice model.
