Literature Pertinent to a Steam Generator Design for a Gas-Cooled Reactor System

References to signiflcant design information for a steam generator in a gas-cooled reactor system are presented. Papers concerning heat transfer and pressure drop correlations for gas flow across banks of bare and circular finned tubes and for subcooled waters boiling water, and superheated steam flow inside pipes are listed and briefly discussed.

Conceptual Design of an Antiproton Generation and Storage Facility (open access)

Conceptual Design of an Antiproton Generation and Storage Facility

The Antiproton Generation and Storage Facility (AGSF) creates copious quantities of antiprotons, for bottling and transportation to remote cancer therapy centers. The #12;first step in the generation and storage process is to accelerate an intense proton beam down the Main Linac for injection into the Main Ring, which is a Rapid Cycling Synchrotron that accelerates the protons to high energy. The beam is then extracted from the ring into a transfer line and into a Proton Target. Immediately downstream of the target is an Antiproton Collector that captures some of the antiprotons and focuses them into a beam that is transported sequentially into two antiproton rings. The Precooler ring rapidly manipulates antiproton bunches from short and broad (in momentum) to long and thin. It then performs some preliminary beam cooling, in the fraction of a second before the next proton bunch is extracted from the Main Ring. Pre-cooled antiprotons are passed on to the Accumulator ring before the next antiprotons arrive from the target. The Accumulator ring cools the antiprotons, compressing them into a dense state that is convenient for mass storage over many hours. Occasionally the Accumulator ring decelerates a large number of antiprotons, injecting them into a Deceleration …

Child Labor in America: History, Policy, and Legislative Issues (open access)

Child Labor in America: History, Policy, and Legislative Issues

The history of child labor in America is long and unsavory. It dates back to the founding of the United States. Traditionally, most children, except for the privileged few, has always worked - either for their parents or for an outside employer. Through the years, however, child labor practices have changed. This report details the history of child labor in American, the Child Labor Under the Fair Labor Standards Act, the re-emergence of the child labor issue in the late 20th century, and child labor initiatives in the 108th,109th, and 110th Congresses.
