Block 2 SRM conceptual design studies. Volume 1, Book 1: Conceptual design package

The conceptual design studies of a Block 2 Solid Rocket Motor (SRM) require the elimination of asbestos-filled insulation and was open to alternate designs, such as case changes, different propellants, modified burn rate - to improve reliability and performance. Limitations were placed on SRM changes such that the outside geometry should not impact the physical interfaces with other Space Shuttle elements and should have minimum changes to the aerodynamic and dynamic characteristics of the Space Shuttle vehicle. Previous Space Shuttle SRM experience was assessed and new design concepts combined to define a valid approach to assured flight success and economic operation of the STS. Trade studies, preliminary designs, analyses, plans, and cost estimates are documented

Study of star formation in RCW 106 using far infrared observations

High resolution far-infrared observations of a large area of the star forming complex RCW 106 obtained using the TIFR 1-metre balloon-borne telescope are presented. Intensity maps have been obtained simultaneously in two bands centred around 150 & 210 micron. Intensity maps have also been obtained at the 4 IRAS bands using HIRES processed IRAS data. From the 150 & 210 micron maps, reliable maps of dust temperature and optical depth have been generated. The star formation in this complex has occured in five linear subclumps. Using the map at 210 micron, which has a spatial resolution superior to that of the IRAS at 100 micron, 23 sources have been identified. The SED and luminosity of these sources have been determined using the associations wit hthe IRAS maps. Luminosity distribution of these sources has been obtained. Assuming these embedded sources to be ZAMS stars and using the mass-luminosity relation, the power law slope of the Initial Mass Function is found to be -1.73+-0.5. This index for this very young complex is about the same as that for more evolved complexes and clusters. Radiation transfer calculations in spherical geometry have been undertaken to fit the SEDs of 13 sources with fluxes in both the TIFR and IRAS bands. From this, the r^-2 density distribution in the envelopes is ruled out. Finally, a correlation is seen between the luminosity of embedded sources and the computed dust masses of the envelopes.Comment: Accepted for publication in MNRAS (21 pages, 8 figures & 3 tables

For the Progress of “Faustus and Helen”: Crane, Whitman, and the Metropolitan Progress Poem

This essay is meant to invigorate a critical discussion of the progress poem—a genre that, while prevalent in American literature, has been virtually ignored by critics and scholars. In lieu of tackling the genre in its entirety, a project too large for just one article, the author focuses the argument through the well-known alignment between Walt Whitman and Hart Crane on the subject of the modern city. It is through the progress poem genre that Crane and Whitman’s peculiar place in metropolitan poetics can best be understood, and it is through their poetry that scholars can begin to approach the broader issue of the progress poem’s place in American literature. Cet article vise à soulever un débat critique au sujet de la poésie du progrès, un genre courant dans la littérature étatsunienne, mais pratiquement ignoré par les critiques et les commentateurs. Plutôt que d’aborder le genre dans son entièreté – un projet qui déborde du cadre d’un article –, l’auteur resserre l’argumentation autour du parallèle bien connu entre Walt Whitman et Hart Crane concernant le traitement de la ville moderne. C’est la poésie du progrès en tant que genre qui permet le mieux de comprendre la place particulière qu’occupent ces deux auteurs dans la poésie métropolitaine, et c’est par leurs poèmes que les chercheurs peuvent aborder la question plus vaste de la place du poème sur le progrès dans la littérature étatsunienne
