Films streaks

Thompson and Mathewman 1983). In this method the silicon crystal is rotated over a continuous angle and a given reflection sweeps out a continuous streak. By digitising the film streak the intensity variation of the reflection gives the A-curve. 

In the present work, we have examined poly(N-vinylcarbazole) (abbreviated hereafter as PVCz) and pyrene-doped poly(aethyl methacrylate) (PMMA) films by using a tine-resolved fluorescence spectroscopic aethod. Fluorescence spectra and their dynanic behavior of the forner fila were elucidated with a high intensity laser pulse and a streak camera, which nakes it possible to neasure dynaaics just upon laser ablation. This aethod reveals aolecular and electronic aspects of laser ablation phenomena (17). For the latter fila a laser pulse with weak intensity was used for characterizing the ablated and Basked areas. On the basis of these results, we demonstrate a high potential of fluorescence spectroscopy in aolecular studies on laser ablation and consider its mechanism. Experimental... 

But this is only half of the transformation. The blackness of the blackface not only masks Jewish physicality but also unites Jack with Mary by casting the actor s whiteness in stark relief. The film self-consciously plays on the white-and-black contrasts inherent in the minstrel form—as when, in one scene backstage, Jack wipes a white glove across his eyes, leaving a white streak across his face —thus heightening the visual impact of Jolson s white skin.69 The white streaking effect is important to Jakie s overall transformation, but it is especially important to his liaison with... 

In order to accurately determine the speed of the flash-across phenomenon, the experiment was repeated and recorded by streak camera with color film. Also thinner SPHF plates were used. In the streak camera trace, 8.5 (isec after each initial wave entered the NM, a hot spot appeared at the surface of each plate and flashed to the center of the chge each at the phenomenal speed of 35 mm/fisec. Cook (Ref 3) considers the flash-across phenomenon to be the heat pulse predicted by M.A. Cook, R. Keyes A.S. Filler (Ref 1)... 

The format or film size, shape and dimension, runs the full range of photographic recording. Early streak cameras consisted of a large strip of film wrapped around a drum electrically driven to rotate at a high speed. (See diagram taken from Ref 26)... 

A somewhat unusual approach is encountered when high-speed motion picture cameras of the Hycam type are used as a streak camera. This is accomplished by filming through the camera s viewfinder which bypasses the prism system that normally cuts up the scene into frames or pictures. After nearly one-fourth of the film has run through the camera the voltage-controlled rate of film travel is reasonably steady and can be used for velocity measurements. 

Stirba and Hurt (S12), 1955 Experimental work on C02 absorption by water films in vertical tubes of length 3 and 6 ft., and dissolution of tubes of solid organic acids by water films. Effective diffusivity exceeds molecular diffusivity, even at 2VRe = 300. Dye streak experiments show that waves cause mixing surfactants damp waves to give continuous dye streak and mass transfer results in agreement with theory. 

By separating the coating from the substrate after deposition, the unique coating features of parylenes, especially continuity and thickness control and uniformity, can be imparted to a freestanding film. Applications include optical beam splitters, a window for a micrometeoroid detector, a detector cathode for an x-ray streak camera, and windows for x-ray proportional counters.
