of alloys, particularly cathodic protection. Particular projects have 
included synthesis and study of copolymers for photographic emulsions, study 
of active fillers for nylon, surface tension and other properties of sil- 
oxanes, copper selenocyanates, and cyanine dyes. In metallurgical research, 
scientists at the University have studied the strengthening of manganese 
steels by heat treatment and deformation, mobility of antimony, iron, and 
cobalt in solid copper, surface tension of the copper-aluminum system, grain 
boundaries of aluminum-copper-nickel alloys, diffusion of zine in aluminum 
by means of zine radioisotopes, dislocations during deformation of Armco iron 
and magnesium, and pulverization of metals by deuterium ions. In welding 
research, problems of arc stability and gas-shielded welding have been 
studied. 
Large-scale research is carried out on semiconductors and semi- 
conductor theory. Projects have included electron migration phenomena in 
metals and alloys, Hall effect and photoconductivity in a magnetic field, 
excess carriers in a magnetic field, thermionic emission of semiconductor 
eathodes, and electrical properties of thin films. Specific semiconducting 
materials whose properties have been studied are copper oxide, germaniun, 
alkali halide crystals, antimony selenide, telluride, and sulfide single 
erystals, and tellurium. 
In physics generally, research investigations have included studies 
of cathodes, plasma, spectral lens structure of X-rays, optical examinations 
of solutions, light absorption and dispersion in crystals, abnormal dis- 
persion of solutions, molecular beams of metals, microwave and are discharge, 
secondary-emission theory, propagation velocity in ultrasonics, quantum field 
theory of deuteron luminescence, and thermionic energy conversion. 
In mechanics, research projects have been carried out in the fields 
of strength and plasticity of metals and alloys, theory of elasticity, 
theory of plates and shells, shock waves, and hypersonic flow. 
Mathematics studies at the University cover boundary-value problems, 
stochastic equations, differential equations, Markov chains, and biharmonic 
equations. In 1957, the University established a computer center equipped 
with a differential analyzer. The center has a universal computer of the 
URAL type. 
In biology, scientists have studied the effects of frost and drought 
on plants. Associated with the University is the Institute of Physiology 
of Man and Animals. This institute has established methods of investigating 
higher nervous activity, conditioned reflexes, and physiology of digestion. 
Also associated with the University is the Nuclear-Research 
Laboratory, which has built a charged-particle accelerator for the production 
of neutrons. The University has an astronomical observatory. Under the 
direction of K. K. Dubinu, Docent, is the Institute for Improving the 
Qualifications of Social-Science Teachers.
