Factors of Fracture Toughness of Plate Steel “In the Third Direction”

The contribution of dendrites of eutectic sulfides and oxides in the fracture of plate steel to the specific work of fracture is evaluated by comparing the fracture toughness of plates in the plane of rolling (Z-direction) and results of studies of fracture surfaces.__________Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 1, pp. 26 – 31, January, 2005.     

Turbulent jet in a channel subjected to archimedes forces

Fundamental regularities of the flow being formed during blowing of a heated jet in a vertical circular channel are found experimentally. An integral method is proposed for computation of such a flow. A comparison of the computation results with experiment is presented.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 55, No. 2, pp. 191–198, August, 1988.     

Pepsinogen messenger RNA of human gastric mucosa and stomach cancer

The cell-free translation method has shown that pepsinogen mRNA is a predominant fraction in the total poly(A)+ RNA from human gastric mucosa. The pepsinogen protein with the molecular weight of 45 kDa has been identified. The level of pepsinogen mRNA decreased in tumours as compared with normal mucosa but in most cases pepsinogen mRNA synthesis depression was not total.
