staff members have been, for the most part, intensive histories of specific 
subjects, such as production of synthetic nitric acid or variable mass 
mechanics, rather than broad, state-of-the-art reports. Studies are pub- 
lished in journals representing the particular field of interest, and 
collections of articles by staff members are periodically, published in a 
Trudy. 
The Institute has a branch in Leningrad and publishes Voprosy 
istorii yestestvoznaniya i tekhniki (Problems of the History of Natural 
Sciences and Engineering) and Nauchnoye nasledstvo. Yestestrenno-nauchnaya 
seriya (Scientific Heritage. Natural Science Series).

Description: 
This institute was established in 1957 as part of the Siberian 
Division of the Academy of Sciences of the U.S.S.R. near Novosibirsk. The 
All-Union Conference on Problems of the Application of Explosions for 
Industrial and Economic Purposes was held on February 16-20, 1959, at this 
institute. The staff of the Institute of Hydrodynamics is very active in 
theoretical and applied studies on the movement of liquid masses, on 
blasting, especially in mining, and in testing of materials. A number of 
devices has been developed here--a pulsed 1,000-atmosphere water thrower, 
a piezo pickup for recording shock-wave pressures, and a device for 
testing stress in tubular samples.
