Wing extension

During World War I, cellulose acetate replaced the highly flammable cellulose nitrate coating on airplane wings and the fuselage fabrics. After World War I, it found extensive use in photographic and x-ray films, spun fibers, and mol ding plastics. [Pg.249]

Applications. Boron fibers are used as unidirectional reinforcement for epoxy composites in the form of preimpregnated tape. The material is used extensively, mostly in fixed and rotary wing military aircrafts for horizontal and vertical stabilizers, mdders, longerons, wing doublers, and rotors. They are also used in sporting goods. Another application is as reinforcement for metal matrix composites, in the form of an array of fibers pressed between metal foils, the metal being aluminum in most applications. [Pg.469]

Cuello was excavated by Hammond and co-workers between 1975 and 1993. It is the earliest known Preclassic Maya site, with a Preclassic occupation from ca. 1200 BC to AD 300 as well as later Classic period (AD 300-900) remains the earliest pottery-using phase (Swasey, 1200-900 BC) has not yet been found at other Preclassic sites, but the Bladen (900-600 BC) and subsequent phases match occupations elsewhere in date and material culture. The Cuello excavations have been extensively described in the report edited by Hammond (1991). Of particular relevance here are the chapters on the ecology and subsistence economy (Ch. 4) by Miksicek and by Wing and Scudder, and on the human burials (Ch. 7), by Frank and Julie Saul. More recent publications have focused on the subsistence economy (Crane and Carr 1994) and on the human skeletal remains (Saul and Saul 1997). [Pg.24]

Optimised for the 1-5 pm wavelength range with extensions into the visible (0.5 pm) and infrared (30 pm), this great winged giant should restore supremacy to the astronomy of the new continent. It is wise to accept the fact and encourage transatlantic cooperation. [Pg.46]

The sexual response of adult males depends on both intrinsic and environmental factors. Males become responsive to the pheromone 6-9 days after adult emergence (Wharton et al, 1954 Hawkins and Rust, 1977). Antennation and erect body posture appear at the same hme during sexual maturation, followed by, in this order, increased locomotion, running, wing-raising, and abdominal extension (Silverman,... [Pg.195]

For the Mexican boll weevil a specially prepared calcium arsenate containing up to 20 per cent, of arsenic pentoxide is effective. This is prepared by heating together white arsenic and precipitated chalk in the presence of excess air at 650° C. The cotton plant is not injured by this preparation.10 In Peru about 30,000 acres of cotton fields are dusted annually from aeroplanes with calcium arsenate. Acid arsenates of calcium appear to be more toxic to boll weevils and to locusts than the basic arsenates. This is probably because the latter must be partially hydrolysed to compounds giving more soluble arsenic before toxic results are produced.11 The extensive application of such sprays to cotton plants is frequently followed by heavy infestations of the cotton aphis. This appears to be due in the first place to the positive photo-tropism of the winged females to white substances such as the arsenate, chalk or flour. Increase of the aphis population is then aided by the destruction by the spray of the hymenopterous parasites of the aphis.12... [Pg.305]

In late summer 1989, I received an English copy of the so-called Leuchter Report, which I have just mentioned, and I read and translated it into German immediately, but the report did not convince me entirely, because it was inexact at points and contained sloppy errors, as I described extensively in a letter to the editor published in the small right-wing monthly newspaper Junge Freiheit in 1990. But the Leuchter Report had embedded the thorn of doubt in my heart. I must now explain what that meant, since therein lies the real reason for my involvement. [Pg.310]

LION. - Symbol of the fixed, Sulphur, when alone. If carrying wings, it represents the volatile, Mercury. The lion represents also the mineral, (green vitriol), from whence is extracted the oil of vitriol, (sulphuric acid), which was so extensively used by the alchemists. The lion opposed to three other animals represents the element. Earth. In fine it is the symbol of the Stone. The lioness represents the volatile. [Pg.103]

Of course, the definition might not be very useful we could also define the ears of an elephant to be wings, but this would not make elephants fly. What makes this definition interesting is a very simple extension. He also argued that the orbit of an electron around a proton would only be stable if its circumference lit R were an integral number of wavelengths. Thus... [Pg.104]

The electroplating of reflective surfaces for exterior mirrors is an important and growing application. Moulding is to a high standard of precision and the electroplated surface creates a mirror with excellent reflection. It will resist impact much better than glass so a longer life in service can be expected— hence, such mirrors are fitted extensively on commercial vehicles, buses, and lorries. ABS is moulded and electroplated also into small mirrors that can be fixed by adhesive on vehicle wing mirrors to cover blind spots . [Pg.185]

In point of fact, the FLQ was itself funded by Bronfman family networks as an extension of earlier efforts to assassinate French President de Gaulle (the story will be told below). The Bronfmans FLQ option was the North American version of the British Special Air Service s control over both the Provisional Wing of the Irish Republican Army and the British Army s counterterror efforts. [Pg.287]

It is apparent that effects of eddy currents and general air turbulence might be approximated by modifying Equations 10 and 14. Modifications of the basic equations could possibly account for solute effects. Extension of the theory to nonaqueous solvents requires the appropriate evaluation of Ap and K. Momentum imparted by vertical spray nozzles affects the time required for droplets to reach terminal fall velocity (II). Helicopter and fixed-wing aircraft impart a downward vector to the bulk of the spray and also produce a turbulent effect on the time of droplet fall and should be accounted for. [Pg.153]
