Textiles and meaning in the lais Guigemar, Lanval, and Laustic of Marie de France.

Through an analysis of Guigemar, Lanval, and Laustic, I show how Marie incorporates textiles into her stories to subvert tropes of misogynistic authority and to assert equality and independence, and to invert traditional gender roles. In Guigemar, a wife uses female knowledge as healing. While keeping her lover tightly-bound through a symbolic exchange, she instructs him in the art of love and ensures his fidelity to her. In Lanval a mysterious Fairy Queen bestows her love upon the receptive and willing Lanval, enacting a reversal of gender stereotypes. From the onset of their relationship she takes on a masculine role and uses feminine sexuality to highlight her exoticism through her erotic dress. In Laustic a wife rescues her lover from her husband’s jealousy by sending him a dead nightingale in embroidered silk. This lai parallels Ovid’s “Philomena” as the heroines in both stories use textiles to relay a message

Noise reduction studies for the Cessna model 337 (0-2) airplane

A study was undertaken to determine the noise reduction potential of the 0-2 airplane in order to reduce its aural detection distance. Static and flyover noise measurements were made to document the noise signature of the unmodified airplane. The results show that significant reductions in aural detection distance can be achieved by the combination of propeller geometry changes and the addition of engine exhaust mufflers. The best results were estimated for the aircraft equipped with a six-blade propeller operating at 3/4 engine speed in combination with a 3.49 cubic foot exhaust muffler installed on each engine. Detection distance for the modified aircraft is estimated to be reduced from about 4-1/4 miles to about 1-1/2 miles when the aircraft is operating at an altitude of 1,000 ft over grassy terrain. Reducing the altitude to 300 ft over a leafy jungle ground cover should reduce the aural detection distance to 0.9 miles. Reduced aural detection distances were also indicated for a modification utilizing a direct-drive six-blade propeller of reduced radius along with smaller exhaust mufflers

Noise reduction studies for the U-10 airplane

A study was undertaken by the NASA Langley Research Center to determine the noise reduction potential of the U-10 airplane in order to reduce its aural detection distance. Static and flyover noise measurements were made to document the basic airplane noise signature. Two modifications to the airplane configuration are suggested as having the best potential for substantially reducing aural detection distance with small penalty to airplane performance or stability and control. These modifications include changing the present 3-blade propeller to a 5-blade propeller, changing the propeller diameter, and changing the propeller gear ratio, along with the use of an engine exhaust muffler. The aural detection distance corresponding to normal cruising flight at an altitude of 1,000 ft over grassy terrain is reduced from 28,000 ft (5.3 miles) to about 50 percent of that value for modification 1, and to about 25 percent for modification 2. For the aircraft operating at an altitude of 300 ft, the analysis indicates that relatively straightforward modifications could reduce the aural detection distance to approximately 0.9 mile. Operation of the aircraft at greatly reduced engine speed (1650 rpm) with a 1.3-cu-ft muffler provides aural detection distances slightly lower than modification 1

»Schwerttag, Kriegstag, Bluttag«. Zu Hanns Heinz Ewers’ Weltkriegsroman "Vampir. Ein verwilderter Roman in Fetzen und Farben" // Hanns Heinz Ewers’ World War Novel Vampir. Ein Verwilderter Roman in Fetzen und Farben

Der Beitrag thematisiert den äußerst umstrittenen, zu Lebzeiten ungemein erfolgreichen, heutzutage jedoch weitgehend in Vergessenheit geratenen deutschen Schriftsteller Hanns Heinz Ewers (1871–1943) und dessen propagandistische, pro-deutsche Rolle im Ersten Weltkrieg, vor allem mit Blick auf seinen während des Krieges verfassten Roman "Vampir. Ein verwilderter Roman in Fetzen und Farben" (1920). Ewers bettet nationale Ideologie in scheinbar harmlose Unterhaltungsliteratur ein, indem er – jedoch nur vordergründig – an die Tradition des Vampir-Genres anknüpft. Die ideologisch-wahnhaft zu verstehende Vampir-Motivik entpuppt sich als Symbol für den deutschen ›Blutdurst‹ während des Ersten Weltkriegs. This paper focuses on the highly controversial German writer Hanns Heinz Ewers (1871–1943), who is today largely unknown, but was extraordinarily popular in his lifetime. During the Great War, Ewers was heavily involved in German propaganda. Around this time, he also wrote his novel Vampir. Ein verwildeter Roman in Fetzen und Farben, which was published in 1920. In this novel, Ewers embeds nationalist ideology into seemingly harmless light fiction. However, the motif of the bloodsucking vampire can be read as a symbol for the German ›bloodthirstiness‹ during World War I
