SPE water electrolyzers in support of the lunar outpost

During the 1970s, the SPE water electrolyzer, which uses ion exchange membranes as its sole electrolyte, was developed for nuclear submarine metabolic oxygen production. These developments included SPE water electrolyzer operation at up to 3,000 psia and at current densities in excess of 1,000 amps per square foot. The SPE water electrolyzer system is now fully qualified for both the U.S. and U.K. Navies with tens of thousands of system hours accumulated at sea. During the 1980s, the basic SPE water electrolyzer cell structure developed for the Navies was incorporated into several demonstrations for NASA's Space Station Program. Among these were: the SPE regenerative fuel cell for electrical energy storage; the SPE water electrolyzer for metabolic oxygen production; and the high pressure SPE water electrolyzer for reboost propulsion reactant production. In the 1990s, one emphasis will be the development of SPE water electrolyzers for the Lunar Outposts Currently defined potential Lunar Outpost applications for the SPE water electrolyzer include: SPE water electrolyzers for metabolic oxygen and potable water production from reclaimed water; and SPE water electrolyzers operating at high pressure as part of stationary and mobile surface energy storage systems

Postmodernism in the Contemporary Novel : Non-linear and Dyssynchronous Elements in the Narratives of The White Hotel, The Golden Notebook, and The French Lieutenant\u27s Woman

This paper seeks to examine theoretical aspects of the narrative by exploring the elements of time and structure that constitute selected novels of D.M. Thomas, Doris Lessing, and John Fowles. Specifically, this paper will explore the spatiotemporal aspects of the narrative, including the impact of chronological arrangement and structural organization on the formation of meaning. The novels examined in this paper-The White Hotel, The French Lieutenant\u27s Woman, and The Golden Notebook- challenge assumptions about the interpretation of narrative and the validity of the novel as commentary on the human condition. Each seeks new ways of narration and new ways to challenge form and tradition. Because these types of confrontation are consistent with a postmodern aesthetic, this paper will examine the theories of such postmodern thinkers as Roland Barthes, Jacques Derrida, and Jean Baudrillard. Doing so will provide background for its exploration into such issues as the use of pastiche by postmodern authors, the presentation of fragmented narratives, the confusion of narrative voice, and the overall challenge to authority that is a defining aspect of postmodernism. The overall purpose of this paper is to consider whether or not the disordered temporality, fragmented structure, confused narration, and oppositional stance of the postmodernism novel signals an abrogation of fictional narrative as a fundamental human activity and need

Closing the Financial Privacy Loophole: Defining “Access” in the Right to Financial Privacy Act

Part I of this Note will discuss the Miller decision and the hole it left in the Fourth Amendment’s protection of financial information left in the hands of trusted third parties. Part II will discuss Congress’s response to Miller in the RFPA. Part III will discuss the cramped interpretation of the RFPA affirmed by the Sixth Circuit, its misapplication of the statute, and policy problems arising from the acceptance of the court’s interpretation. Part IV will discuss statutory injuries and how the ambiguous outcome of the Spokeo case could threaten financial privacy protections generally and those specifically provided by the RFPA. Part V will discuss the proposed solution to the problem

Recent advances in SPE (tm) water electrolyzer

A new cell structure has been introduced into the SPE Water Electrolyzer which has improved overall characteristics significantly. Weight, reliability, and efficiency are the characteristics that are improved the most, with volume having a second order improvement. This paper discusses the capabilities of the new cell structure and the impact it would have in various space applications

Annular Array Search Units and Their Potential Application in Conventional Ultrasonic Testing Systems

This paper is based on a program to investigate the potential of multi-element annular arrays for practical application in ultrasonic testing systems. The annular array is comprised of coaxially-located, ring-shaped piezoelectric elements. By providing excitation pulses in a spherical time relationship, the transmitted beam may be focused at a specific range. By electronic switching, the focal point can be placed at various distances in the material under examination, Of particular interest is the length over which the beam can be held in collimation. Fabrication methods, delayed excitation techniques, and beam patterns in water and steel are described

Vortex avalanches in the non-centrosymmetric superconductor Li2Pt3B

We investigated the vortex dynamics in the non-centrosymmetric superconductor Li_2Pt_3B in the temperature range 0.1 K - 2.8 K. Two different logarithmic creep regimes in the decay of the remanent magnetization from the Bean critical state have been observed. In the first regime, the creep rate is extraordinarily small, indicating the existence of a new, very effective pinning mechanism. At a certain time a vortex avalanche occurs that increases the logarithmic creep rate by a factor of about 5 to 10 depending on the temperature. This may indicate that certain barriers against flux motion are present and they can be opened under increased pressure exerted by the vortices. A possible mechanism based on the barrier effect of twin boundaries is briefly discussed
