This extensively revised and updated fourth edition provides engineers with the principles and tools needed to turn their familiarity with earlier ACI Codes into more profitable, time-saving routine designs. Created to be used with the ACI Code and Commentary, this outstanding guide follows the new Code format with information covered in more specific sections and subsections in order to enhance clarity. In addition, it shortens the time needed for computer-aided design and analysis, converts code formulas from the review form to direct design, and presents simple formulas, tabulations, and charts for conservative longhand direct design. Two convenient indices - a subject index and a 1995 Code section index - are provided, enabling engineers to quickly locate all Code references to a particular topic, as well as concise interpretation of a given Code section. The Guide also saves engineers time and effort on the job with its detailed coverage of: torsional stiffness, braced and unbraced slender columns with and without sidesway, wide-module joist systems, reinforcement details for economy in design, detailing, fabricating, field erection, and inspection, latest ASTM material specifications, anchorage, development, and splice requirements, high-strength concrete, comparisons between wall and column economy, structural plain concrete. More than ever, the sure-handed Structural Design Guide to the ACI Building Code is an indispensable practical reference for structural, civil, and architectural engineers and students who want to safely meet modern building requirements while taking full advantage of every economy permitted by the 1995 ACI Code.

I I This book is intended to guide practicing structural engineers into more profitable routine designs with the AISC Load and Resistance Factor Design Specification (LRFD) for structural steel buildings. LRFD is a method of proportioning steel structures so that no applica ble limit state is exceeded when the structure is subjected to all appro priate factored load combinations. Strength limit states are related to safety, and concern maximum load carrying capacity, Serviceability limit states are related to performance under service load conditions such as deflections. The term "resistance" includes both strength states and serviceability limit states. LRFD is a new approach to the design of structural steel for buildings. It involves explicit consideration of limit states, multiple load factors and resistance factors, and implicit probabilistic determination of relia bility. The type of factoring used by LRFD differs from the allowable stress design of Chapters A through M of the 1989 Ninth Edition of the AISC Specifications for Allowable Stress Design, where only the resistance is divided by a factor of safety to obtain an allowable stress, and from the plastic design provisions of Chapter N, where the loads are multi plied by a common load factor of 1.7 for gravity loads and 1.3 for gravity loads acting with wind or seismic loads. LRFD offers the structural engineer greater flexibility, rationality, and economy than the previous 1989 Ninth Edition of the AISC Specifications for Allowable Stress Design."

The discovery and concept that Helicobacter pylori is associated with gastric disease including gastric cancer which is one of the most common and frequently lethal forms of malignancy, heralded a new and rapidly expanding field recognizing the emergence of many new pathogens and disease syndromes in clinical medicine, as well as basic infectious disease research. There is now an extensive and widely known literature of how H. pylori is involved in a wide variety of disease syn dromes. As summarized in the introductory chapter of this volume, many major advances have been made in diagnosis, both serologic and endoscopic in time of the involvement of this organism in patients with upper GI ailments as well as its presence in those who are not clinically ill. The Introduction describes the rapid development of understanding the role of this organism in disease. The basic bacteriology of H. pylori is then described in the second chapter. Diagnostic tests for detecting H. pylori infection is then highlighted, as well as the role of such infection in gastric cancer. Current knowledge concerning risk factors and peptic ulcer pathology associated with H. pylori is then described. Newer information concerning therapy of H. pylori infection and colonization is described in a subsequent chapter as well as one concerning the effects of anti biotics on H. pylori infection. The extensive literature on natural substances with anti-H."

Employing both large-scale surveys and in-depth interviews, the authors document the mental health effects on workers caused by the closure of four General Motor plants. They paint a portrait of how the social context in which these workers lived played a critical role in their experiences of unemployment or of keeping their jobs when others around them lost theirs. More than simply a study of unemployment and mental health, this book is also a story of coping and resilience.

Most research on the president's relationship with the public focuses on modern presidents because they frequently give speeches in the attempt to build public support for their policy goals. Expanding the concept of presidential communication beyond policy speeches, Popular Leadership in the Presidency: Origins and Practice reveals the extent to which presidents have always communicated with the public. And it is not simply the existence of public communication that is significant, but the fact that structural elements of the presidency encourage a connection with the people. The fact that the executive consists of one individual, the symbolic authority that devolves on the president as the sole national leader, and a selection process that in practice turned out to be popular all encourages a relationship with the people. An examination of the first four presidents demonstrates the broad range of public persuasion practiced by early presidents as well as the way in which the structural encourages that behavior.

This book is intended to guide practicing structural engineers familiar with ear lier ACI building codes into more profitable routine designs with the ACI 1995 Building Code (ACI 318-95). Each new ACI Building Code expresses the latest knowledge of reinforced concrete in legal language for safe design application. Beginning in 1956 with the introduction of ultimate strength design, each new code offered better uti lization of high-strength reinforcement and the compressive strength of the con crete itself. Each new code thus permitted more economy as to construction material, but achieved it through more detailed and complicated design calcula tions. In addition to competition requiring independent structural engineers to follow the latest code for economy, it created a professional obligation to fol low the latest code for accepted levels of structural safety. The increasing complexity of codes has encouraged the use of computers for design and has stimulated the development of computer-based handbooks. Before computer software can be successfully used in the structural design of buildings, preliminary sizes of structural elements must be established from handbook tables, estimates, or experienced first guesses for input into the com puter."

Knowledge of and experience with the basic technique of vaginal hysterectomy is not univers al. Each surgeon must learn to identify and appreciate the dimensions of individual variation in anatomic findings and therefore surgical technical decisions and their execu tion from one patient to another. Unexpected surgical difficulty can be predicted, but ultimately it is dealt with retrospectively. Skilled practitioners must study the particular patient and her problem comprehensively and allow for such individual variations in find ings and technical needs as are necessary to the surgical solution for that patient's problem. Recognizing these factors, Drs. Hoffman and Spellacy have orga nized and prepared a comprehensive monograph concerning this very real clinical entity. They have reviewed the experience of con temporary surgeons and blended these recommendations with their own experience in a useful compendium of surgical knowledge about this important subject. Their monograph is recommended not as a replacement for the many other fine surgical texts available to the reader but as a supplement to the surgeon's library. It is for those surgeons who, having mastered the basic techniques, are in terested in extending the frontiers of personal knowledge of this provocative subject and safely broadening the indications for effec tive surgery and reconstruction.
