This synthesis will be of interest to highway environmental engineers, noise analysts, design engineers, maintenance personnel, planners, administrators, and others responsible for the design, selection, and maintenance of noise barriers or other traffic noise abatement policies. Information is provided on current state practice associated with noise abatement techniques and on the various products that are used. This synthesis describes the state of the art with respect to traffic noise abatement procedures, especially noise barriers. This report of the Transportation Research Board provides information on the design, construction and maintenance of both new (Type I) and retrofit ( Type II) noise barriers. The design elements that are addressed include materials, the selection process, service life, foundations, drainage, aesthetics, and safety. The construction section covers technical problems related to surface effects, durability, snow damage, and costs. Other noise abatement measures such as insulation and highway design alternatives are also addressed. The issue of public demand and availability funding is included, and recommendations are made to improve the situation.
Since its first edition over 60 years ago, Rockwood and Green’s Fractures in Adults has been the go-to reference for treating a wide range of fractures in adult patients. The landmark, two-volume tenth edition continues this tradition with two new international editors, a refreshed mix of contributors, and revised content throughout, bringing you fully up to date with today’s techniques and technologies for treating fractures in orthopaedics. Drs. Paul Tornetta III, William M. Ricci, Robert F. Ostrum, Michael D. McKee, Benjamin J. Ollivere, and Victor A. de Ridder lead a team of experts who ensure that the most up-to-date information is presented in a comprehensive yet easy to digest manner.
Lincoln’s First Crisis concerns five of the most consequential months in American history: December 1860 through April 1861. When Abraham Lincoln swore his oath as president, the United States was disintegrating. Seven states had seceded, and as many as eight seemed poised to join them, depending upon how the new president handled the secession crisis and its flashpoint: Fort Sumter in South Carolina, the heart of the rebellion. The fate of the republic hung in the balance. The Sumter crisis has been hotly debated and deeply researched for more than 150 years. In this thoughtful reassessment, William Bruce Johnson combines thorough research and the latest historiography with a litigator’s methodical analysis and a storyteller’s eye for meaningful detail. Shortly after taking office, Lincoln decided upon a plan to avoid war with the seceded states while keeping his inaugural promise to maintain a Union military presence in the South. Because he chose not to reveal his plan to anyone, rumors soon spread that he was simply afraid to act. One source of such rumors was Lincoln’s secretary of state, William Henry Seward. Resentful that Lincoln had deprived him of the Republican nomination and convinced that Lincoln lacked the political sophistication necessary to deal with the secession crisis, Seward decided to negotiate with the Confederacy on his own and in secret. General Winfield Scott, meanwhile, the Union’s most senior military officer, had for a decade depended upon Seward for political advice, and now considered himself under orders from Seward, not the president. Johnson traces how Seward and Scott sabotaged Lincoln’s plan. From this account, from his examination of various personalities (such as that of Fort Sumter’s commander, Major Robert Anderson), and from his granular research into aspects of the Order of Battle in Charleston, Johnson has here constructed a new narrative of this crucial period, culminating in a new theory of how and why the Civil War began as it did, and how and why, if the new president’s orders had been properly carried out by Seward and Scott, it might have been averted.
