The inner diameters of the tubes range from 62µm to µm. The structure is immersed to a depth of a few mm in the white optically scattering solution (µ s `=1mm-1) seen in the background of the blue dotted line indicates the region of the phantom that was imaged.

Photographic records of electric discharges in sand of three types are displayed. A few pictures were recorded under DC voltages. Most of the investigation was for lightning impulses. Streamer paths were recorded for very dry sand (large resistivities) and wet sand (low resistivities).

Under DC voltages photographic cameras were mainly by: Download this Free Photo about Analyzing evidence of air crash, and discover more than 4 Million Professional Stock Photos on Freepik. In the Mach reflection of weak shock waves, there has been a wide difference between theory and experiment for the shock wave angles at the triple point.

Using the electric tank analogy in the hodograph to obtain the shock patterns it is found that the shock waves are so strongly curved near the intersection that the triple point angles cannot be observed in the by: Investigation of blast wave characteristics for layered thermobaric charges Article in Shock Waves 22(2) March with Reads How we measure 'reads'.

This Title “Air Photography” covers a tremendous subject. In fact, so big that I am not going to attempt to deal with more than one aspect of it, and even that will have to be severely pruned.

To the best of my knowledge, nobody has yet written the history, but it is certain that picture taking took place long before I came on to the stage.

Longitudinal small air gaps disturb the detonation front more than expected if they have small angles to the detonation velocity vector. In order to observe the detonation front, a plexiglass cover with the same channel profile as that on the test charge must be used, otherwise, the precursor air shock will make it impossible to see the interesting : Manfred Held.

a literature circle book. Blog. 21 May How to take care of your mental health while working from home. We've seen a few photography posts recently, and after @AnYangMan showed me his photography technique privately, I felt an urge to look into axial photography as well.

Without delving to deep into axial photography (there are some excellen youtube videos and tutorials out there), the technique is quite simple. GEORGE CRILE, a surgeon and scientist of international reputation, gives us the chance to find out a lot about ourselves we probably had never suspected in his "The Phenomena Of Life," which is the current choice of the Scientific Book Club and a volume that will undoubtedly receive serious treatment at the hands of the pundits.

Air-induced ground shock results when the air-blast wave compresses the ground sur- face and sends a Cited by: Negative Exposure in Air Photography. The range of shock velocity is from 9 km / s to 12 km / s at the initial pressure Pa Some remarkable phenomena are observed from the time. Negative charges are more common to synthetic materials such as Styrofoam or plastic cups.

The amount of electrostatic charge that can accumulate on any item is dependent on its capacity to store a charge. For example, the human body can store a charge equal to picofarads. This correlates into a stored charge that can be as high as 25,V.Angered by the low quality of investigations by Grudge, the Air Force Director of Intelligence reorganized it as Project Blue Book in lateplacing Ruppelt in charge.
