An embankment that is washed away can be repaired or restored by replacing the washed away earth, which is necessarily large because embankments have a gentle slope. A quicker method is to replace the washed out earth with a criss-cross structure of timber steepers called a pigsty which is only slightly wider than the track itself. The pigsty ...
In addition, with this way of processing, the possibility of a chemical decomposition of the hydro peroxides is possible by adding a corresponding P-stabilizer directly when plasticizing. The destruction of the hydro peroxide groups is, with other processes, already carried out during the last step of flake treatment for instance by adding H 3 ...
In photography, washing is an important part of all film processing and printmaking processes. After materials have been fixed, washing removes unwanted and exhausted processing chemicals which, if left in situ, may cause deterioration and destruction of the image.
Precautionary statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). [1] They are intended to form a set of standardized phrases giving advice about the correct handling of chemical substances and mixtures, which can be translated into different languages.
In modern swept wing aircraft, yaw damping control systems are used to dampen and stabilize the Dutch-roll motion of an aircraft in flight. However, when a pilot inputs a command to yaw the aircraft for maneuvering (such as steady turns), the rudder becomes a single control surface that functions to dampen the Dutch-roll motion and yaw the aircraft.
A USAF Boeing B-52G Stratofortress, 57-6493, of the 68th Bomb Wing, Seymour Johnson AFB, North Carolina, crashed near Aiken, South Carolina, when the aircraft suffered major structural failure due to a major fuel leak with the right wing separating between the third and fourth engine nacelles, the wing then shearing off the horizontal ...
His body was never recovered. An Accident Investigation Board determined that the crash was caused by the structural failure of the honeycomb material supporting the leading edge of the port vertical stabilizer during a high-speed test dive. A section of the leading edge, approximately 6 X 3 feet, broke away. [40] "The doomed F-15C was flying ...
