Abstract Fluoroprene, the first fluorine-containing elastomer, was developed by E. I. du Pont de Nemours … Company and reported by Mochel and others in 1948. However, intensive research to develop specialty rubbers from fluorocarbons was not started until the early 1950's. At the time, there was an urgent military need for fuel and chemical resistant rubbers for service under extremely low temperatures. Consequently, most of the fluorine-containing elastomers were the result of research conducted or sponsored by the Department of Defense. Army experiences in the Aleutians during World War II and in several task force operations in the Arctic regions showed, among others, that fuel hoses became brittle and cracked. Gaskets failed to function. On shipboard, the Navy was experiencing similar difficulties with rubber items. The Air Force, on the other hand, was being plagued with an epidemic of fuel leakage on many of its aircraft. The extraction of the plasticizers from the nitrile rubber compounds and the low temperature of the environment caused shrinkage of the seals and gaskets resulting in leakage of fuels. Obviously, a solution to these problems was to develop new fuel resistant rubbers which would be inherently flexible at extremely low temperatures.

The evolution of a cost/schedule control system (C/SCS) for direct labor in naval shipyards can be traced from the cost/schedule control concept used in the Air Force in the 1960s as an initiative toward more reliable data. Subsequent C/SCS programs were initiated across the Department of Defense (DoD) in the late 1960s and early 1970s. As private shipyards came under what is known as cost/ schedule control system criteria (C/SCSC), and its validation requirements, the issue of C/SCS in naval shipyards rose to the surface. In 1984, the Naval Sea Systems Command (NAVSEA) issued a directive which called for C/SCS implementation in naval shipyards. Expanded use and standardization has followed. This paper reviews basic C/SCS principles, how naval shipyards have used C/SCS in improving performance, and how it has been standardized while still retaining a degree of flexibility.

ABSTRACT The Tri-Service Microbiome Consortium (TSMC) was recently established to enhance collaboration, coordination, and communication of microbiome research among Department of Defense (DoD) organizations. The TSMC aims to serve as a forum for sharing information related to DoD microbiome research, policy, and applications, to monitor global advances relevant to human health and performance, to identify priority objectives, and to facilitate Tri-Service (Army, Navy, and Air Force) collaborative research. The inaugural TSMC workshop held on 10 to 11 May 2017 brought together almost 100 attendees from across the DoD and several key DoD partners. The meeting outcomes informed attendees of the scope of current DoD microbiome research efforts and identified knowledge gaps, collaborative/leveraging opportunities, research barriers/challenges, and future directions. This report details meeting presentations and discussions with special emphasis on Tri-Service labs’ current research activities.
