Corallistine, a new polynitrogen compound from the sponge Corallistes fulvodesmus L. and L.

Two polynitrogen compounds 1-methyl-pteridine-2,4-dione 1b and corallistine 2 were isolated from the new-caledonian sponge #Corallistes fulvodesmus$ L. & L. The structure of corallistine was determinated by X-ray single crystal analysis of its 6'-isobutyloxycarbonyl derivative 3. (Résumé d'auteur

The Admiralty, Popular Navalism, and the Journalist as Middleman, 1884-1914

The three decades before the First World War were a period of intense militarism, and in the United Kingdom this meant navalism. By the late Edwardian period the navalist movement had captured Britain’s attention – a movement that paradoxically claimed the Royal Navy was weaker than at any point in its history while presiding over a total revolution in British naval technology and a concurrent unprecedented rise in naval budgets. This dissertation explores the creation, propagation, success and failure of directed navalism between 1884 and 1914. Directed navalism, for the purposes of this project, refers to the cooperation between and support of navalism among three elite national groups: serving naval officers at the level of captain and above (professionals), naval correspondents and editors working for large circulation national newspapers and periodicals (press), and members of Parliament in both houses, from backbenchers to high Cabinet-level officials, who dealt with navalist issues during the course of their public service careers (politicians). Directed navalism was the bedrock upon which the more popular and ultimately more successful ‘soft’ navalism – penny dreadfuls, the Navy League, fundraising drives, fleet reviews – was built. The three groups of professionals, press and (to a lesser extent, particularly before 1900) politicians purposefully created and fostered the navalist movement. Navalism meant different things to each of the three, obtainable via different methods, but from 1884 onward they were able to put aside their differences in service to a broader movement. This unofficial partnership remained effective through the majority of the Edwardian period, but after the twin upheavals of Liberal electoral victory and First Sea Lord Sir John (Jacky) Fisher’s naval reforms in 1906 it began to be overtaken by partisanship, factionalism, and a general radicalization of both public and parliamentary navalism. The rise and fall of directed navalism – the backroom deals, surreptitious leaks and midnight meetings that laid the foundation for a national movement – is the story of this dissertation. Though directed navalism collapsed before the First World War, it was extraordinarily successful in its time, and it was a necessary precursor for the creation of a national discourse in which ‘soft’ navalism could thrive

Design document for the Surface Currents Data Base (SCDB) Management System (SCDBMS), version 1.0

The Surface Currents Database Management System (SCDBMS) provides access to the Surface Currents Data Base (SCDB) which is maintained by the Naval Oceanographic Office (NAVOCEANO). The SCDBMS incorporates database technology in providing seamless access to surface current data. The SCDBMS is an interactive software application with a graphical user interface (GUI) that supports user control of SCDBMS functional capabilities. The purpose of this document is to define and describe the structural framework and logistical design of the software components/units which are integrated into the major computer software configuration item (CSCI) identified as the SCDBMS, Version 1.0. The preliminary design is based on functional specifications and requirements identified in the governing Statement of Work prepared by the Naval Oceanographic Office (NAVOCEANO) and distributed as a request for proposal by the National Aeronautics and Space Administration (NASA)

Perpendicular momentum injection by lower hybrid wave in a tokamak

The injection of lower hybrid waves for current drive into a tokamak affects the profile of intrinsic rotation. In this article, the momentum deposition by the lower hybrid wave on the electrons is studied. Due to the increase in the poloidal momentum of the wave as it propagates into the tokamak, the parallel momentum of the wave increases considerably. The change of the perpendicular momentum of the wave is such that the toroidal angular momentum of the wave is conserved. If the perpendicular momentum transfer via electron Landau damping is ignored, the transfer of the toroidal angular momentum to the plasma will be larger than the injected toroidal angular momentum. A proper quasilinear treatment proves that both perpendicular and parallel momentum are transferred to the electrons. The toroidal angular momentum of the electrons is then transferred to the ions via different mechanisms for the parallel and perpendicular momentum. The perpendicular momentum is transferred to ions through an outward radial electron pinch, while the parallel momentum is transferred through collisions.Comment: 22 pages, 4 figure
