Autor: O A, Levada, A V, Trailin, A L, Kvitka, O V, Stolbinskaia

Publikováno v: Likars'ka sprava. (1-2)

Auditory P300 latency and amplitude values were assessed in 11 elderly persons without cognitive impairments (WCI), mean age--(70.73 +/- 4.24) years, 20 patients with subcortical vascular mild cognitive impairment (SCMCI), mean age--(75.35 +/- 5.48)

We analyze the stressed state of pipeline T-joints in which the connecting pipe makes an angle of 90° or 45° with the main pipe under the action of torques and bending moments causing the out-of-plane torsion and bending of the T-joint. The influen

We propose a procedure of numerical analysis of three-dimensional thermal stressed states of machine parts with multiplayer heat-shielding coatings based on the use of the SPACE finite-element software package. A detailed analysis of thermal and stre

Analysis of the stressed state in equal-diameter T-joints of pipelines. Part 1. Action of internal pressure and bending moments in the plane of a T-joint

Publikováno v: Strength of Materials. 30:645-650

We analyze the stressed state of two types of T-joints in which the union makes angles of 45° and 90° with the main pipe. The character of the distribution of stresses in a T-joint illustrates the distinctive features of its operation under the act
