Description: 
Much of the research of this institute is of a mathematical nature. 
Some examples are as follows: application of the averaging principle, first- 
order differential equations, linear-differential-equation systems, question 
of stability according to the first approximation, accuracy of a position of 
a point, some problems of the nonlinear theory of elasticity, scattering of 
plane sonic waves by a spherical obstacle (for short wavelengths), and 
molecular-light-scattering theory. Some work has been reported on machining, 
on the cutting of gears, and on the high-speed machining of spherical surfaces. 
The Institute offers courses in mining, development of mineral 
deposits, mining equipment, automation, mine construction, reinforced-concrete 
structures, heating and ventilation, prefabricated construction, plumbing, 
higher mathematics, physics, geology, and resistance of metals. 
The Institute, which has a branch in Stalinogorsk, has published a 
Nauchnyye Trudy.

Description: 
This institute was established in 1938 to prepare secondary-school 
teachers. Studies of electrochemistry, magnetohydrodynamics, and plasmas, 
particularly nonlinear vibrations of ions in a plasma, have been conducted. 
Courses are offered in Russian language, literature, and history, mathematics 
and drafting, and physics and fundamentals of production.
