Metallic compounds in the Ti−Cu system

Conclusions In alloys of the Ti–Cu system we found the Ti₃Cu phase at a concentration of 25 at % Cu formed at 1000°C by the peritectic reaction L+Ti₃Cu.Siberian Metallurgical Institute. Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 2, pp. 10–11, February, 1967.     

Stress relaxation in InGaAsP/InP heterostructures for 1064-nm laser radiation converters

Technical Physics Letters - Specific features of mechanical-stress relaxation in InGaAsP/InP heterostructures for 1064 nm laser radiation converters have been studied. It is established that stress...     

Steady states of a biotechnological process for producing lactic acid at a given substrate concentration in the inlet stream

Relationships are derived that form the domain in which the multiplicity of steady states exists for the continuous process of lactic acid production in a fermenter with stirring. Algorithms are described for estimating the technological characteristics of the process under the conditions of multiplicity. Methods and results of calculations are presented for different variants of specifying the concentration of a substrate in the inlet stream, and examples of numerical calculations are given.

Trappean magmatism as the basic cause of coal metamorphism and hydrocarbon generation in the Tungus Coal Basin

A survey is presented for coal reserves and possible amounts of methane and other gases in the Tungus Coal Basin, where brown coal is metamorphized to various (down to anthracites) stages under the action of heat generated by many trappean intrusions. There is a presumption that some hydrocarbon gases are in a fossil state. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 6, pp. 72–80, November–December, 2005.
