Effect of the heat treatment and plastic deformation of high-strength corrosion-resistant nitrogen-bearing steels on their wear resistance during sliding friction

Wear-resistance sliding-friction tests of high-strength corrosion-resistant nitrogen-bearing 08Kh14AN4MDB and 05Kh22AG15N8M2F steels have been performed for different structural states under sliding-friction conditions. The wear resistance of these steels depends on the intensity of the strain hardening of austenite. The martensitic-austenitic 08Kh14AN4MDB steel has a higher wear resistance if it has a high nitrogen-austenite concentration. The dependence of the weight loss of the 05Kh22AG15N8M2F and 12Kh18N10T steels on the test time is found to be linear.     

Microprocessor system for controlling household electronic equipment

We propose three variants for systems for controlling household heating devices. We consider the feasibility of using these systems in various household consumer services (for therapeutic purposes, security systems, etc.). Translated from Izmeritel’naya Tekhnika, No. 7, pp. 30–32, July, 1999.     

Diagnosis of restorable components of special-purpose on-board data-acquisition systems

The diagnosis of restorable components of special-purpose on-board data-acquisition systems containing continuous and discrete devices is analyzed. Translated from Izmeritel'naya Tekhnika, No. 7, pp. 17–19, July, 2000.     

Information features of multi-extremal functions for describing the functioning indicators of the components of information measurement systems

The questions are considered of estimating the information content of the extrema of multi-extremal functions which are of great practical significance for numerically solving a number of applied problems and, in particular, for estimating the spectral power density of steady-state random processes when choosing a numerical method for approximating the multi-extremal functions, etc. Translated from Izmeritel'naya Tekhnika, No. 8, pp. 19–21, August, 2000.     

Study of neuroblastomas in children using a complex of monoclonal antibodies

The possibility to reveal the following types of neuroblastoma is described: with c-ALL-antigen; with Thy-1-antigen (ICO-10); with granulocytic antigen (ICO-G2); with B-cell antigen (IPO-10). Immunocompetent cells in the tumour may be studied with the use of monoclonal antibodies ICO-1, ICO-11, ICO-GM-1, OKT3, IPO-3.     

Estimating the total error for a distributed group standard for time and frequency

Studies have been made on the systematic and random errors in the group frequency and time scale for a distributed group standard for the units of time and frequency. A new approach has been devised for calculating the total error of secondary standards. __________ Translated from Izmeritel’naya Tekhnika, No. 6, pp. 24–26, June, 2008.
