    The American woman as she has been represented in a select number of American plays produced on the American stage from 1920 to 1930 forms the subject of this study. Particular consideration has been given to such matters as the thoughts, feelings, manners, morals, and social conduct of the women in the plays - all of which throw light on the behavior, characteristics, and ideals of the woman of the twenties as she was presented on the American stage

    Extended flight evaluation of a near-term pitch active control system

    Get PDF
    Fuel savings can be achieved by moving the center of gravity of an aircraft aft which reduces the static stability margin and consequently the trim drag. However, flying qualities of an aircraft with relaxed static stability can be significantly degraded. The flying qualities can be restored by using a pitch active control system (PACS). This report documents the work accomplished during a follow-on program (see NASA CR-165951 for initial program report) to perform extended flight tests of a near-term PACS. The program included flying qualities analyses, piloted flight simulation tests, aircraft preparation and flight tests to demonstrate that the near-term PACS provided good flying qualities within the linear static stability envelope to a negative 3% static stability margin

    The English Language: How the French Normans Changed its Trajectory through the Onset of the Battle of Hastings

    The English Language: How the French Normans Changed its Trajectory through the Onset of the Battle of Hastings Abstract This capstone discusses the convoluted connection between Denmark, England, and Normandy and identifies how this complicated shared history led to William the Conqueror’s infiltration of England, via Normandy. Subsequently, the Battle of Hastings promptly follows, ultimately ushering in a new era within Anglo-Saxon England. This pivotal event established the prevalence of the French language within the English language in a variety of capacities, especially pertaining to sub-sections within culture. These various sections within culture are related to the military, law, government, cuisine, fashion, and art. To highlight the occurrence of French lexicon strewn throughout the English language a variety of poems spanning from Medieval England to eighteenth century England were implemented as primary source quotations. The Oxford English Dictionary served as chief consultant to ascertain each word’s etymology within each poem included in this research paper

    A wind-tunnel investigation at high subsonic speeds of the lateral control characteristics of various plain spoiler configurations on a 3-percent-thick 60 degree delta wing

    Get PDF
    Results are presented of wind-tunnel investigations at Mach numbers of 0.60 to 0.94 and angles of attack of -2 degrees to about 24 degrees to determine the lateral control characteristics of spoilers with various wing chord-wise and spanwise locations and spoiler spans and deflections on thin 60 degree delta wing of NACA 65a003 airfoil section parallel to free stream

    Amorphous metallizations for high-temperature semiconductor device applications

    Get PDF
    The initial results of work on a class of semiconductor metallizations which appear to hold promise as primary metallizations and diffusion barriers for high temperature device applications are presented. These metallizations consist of sputter-deposited films of high T sub g amorphous-metal alloys which (primarily because of the absence of grain boundaries) exhibit exceptionally good corrosion-resistance and low diffusion coefficients. Amorphous films of the alloys Ni-Nb, Ni-Mo, W-Si, and Mo-Si were deposited on Si, GaAs, GaP, and various insulating substrates. The films adhere extremely well to the substrates and remain amorphous during thermal cycling to at least 500 C. Rutherford backscattering and Auger electron spectroscopy measurements indicate atomic diffussivities in the 10 to the -19th power sq cm/S range at 450 C

    [Special Issue on SEA Demographics] Response - Language Policy: Using the American Community Survey to Investigate Bilingualism and Biliteracy among Immigrant Communities

    Get PDF
    This article is a response to Mark Pfeifers Cambodian, Hmong, Lao and Vietnamese Americans in the 2005 American Community Survey and elaborates on the utility of the American Community Survey (ACS) for studying immigrant groups in the United States of America, and also compares the ACS to the U.S. Census. Neither the Census nor ACS questionnaire is structured to capture the language and literacy skills of immigrant communities in as far as these surveys only collect information about respondents oral language abilities, with a focus on English fluency. Direct, self-reported, and surrogate measures of literacy are discussed, with a proposal to use education level as surrogate for literacy. Using the Vietnamese subpopulation in the ACS, examples are presented of ways to construct composite variables from the ACS raw microdata, to measure respondents bilingualism and biliteracy. When such new variables are used in analysis of immigrant communities, a more complex multilingual picture emerges than is presented normally in Census and ACS data products available to the public

    On the amino acids of sponges

    Get PDF
    The distribution of amino acids in 14 sponges was surveyed qualitatively by paper chromatography. Dried acetone-extracted sponge material was treated with 95% alcohol to remove soluble amino acids and peptides. From two sponges this material consisted largely of peptides, five of which were hydrolyzed and examined. From the present data it appears doubtful that any significant correlation exists between the amino acid distribution in sponges and the biological classification of these organisms
