Spenser and the Historical Revolution: Briton Moniments and the Problem of Roman Britain

Curran argues that, since Roman Britain is a key to understanding the historiographical debates of Edmund Spenser\u27s time, the Roman Britain section of Briton Moniments in The Faerie Queene needs to be examined. It is here that Spenser acknowledged the direction historiography was taking, and saw how this new trend altered the relation between history and glory

Arcjet thermal characteristics

The performance of water-cooled and radiation cooled arcjet thrusters operating on both 1:2 nitrogen/hydrogen mixtures at 1 to 2 kW and on pure hydrogen at 1 to 4 kW are compared. To investigate the effects of test facility background pressure on performance, data were taken for both thruster operating on nitrogen/hydrogen mixtures at facility background pressures nominally at 0.20 Pa and 20 Pa. It is shown that increasing the background pressure decreased the thruster performance, and simple pressure area corrections alone could not account for observed degradation in performance

Galvanic Liquid Applied Coating Development for Protection of Steel in Concrete

Corrosion of reinforcing steel in concrete is a major problem affecting NASA facilities at Kennedy Space Center (KSC), other government agencies, and the general public. Problems include damage to KSC launch support structures, transportation and marine infrastructures, as well as building structures. A galvanic liquid applied coating was developed at KSC in order to address this problem. The coating is a non-epoxy metal rich ethyl silicate liquid coating. The coating is applied as a liquid from initial stage to final stage. Preliminary data shows that this coating system exceeds the NACE 100 millivolt shift criterion. The remainder of the paper details the development of the coating system through the following phases: Phase I: Development of multiple formulations of the coating to achieve easy application characteristics, predictable galvanic activity, long-term protection, and minimum environmental impact. Phase II: Improvement of the formulations tested in Phase I including optimization of metallic loading as well as incorporation of humectants for continuous activation. Phase III: Application and testing of improved formulations on the test blocks. Phase IV: Incorporation of the final formulation upgrades onto large instrumented structures (slabs)
