Turning Tool Wear Estimation Based on the Calculated Parameter Values of the Thermodynamic Subsystem of the Cutting System.

Today, modern metalworking centers are not yet able to reliably assess the degree of wear of the tool used in metal cutting. Despite the fact that a large number of methods for monitoring the service life of the tool have been developed, this issue still remains a difficult task that needs to be solved. Idea: The article proposes a new, previously unused method for estimating the power of a cutting wedge in metalworking.

[Regional vasoactive and metabolic therapy of patients with severe cranio-cerebral traumas].

In patients with severe cranio-cerebral traumas an investigation was performed of the efficiency of using vasoactive therapy in complex treatment directed to earlier recovery of the microcirculatory blood flow and aerobic metabolism in ischemic parts of the brain.

[The early rehabilitation of the patients following extensive liver resection and transplantation].

This study included 500 patients who had undergone extensive liver resection and transplantation of whom 250 were treated with the use of remedial gymnastics, physiotherapeutic factors, and massage. The positive dynamics of objective characteristics of the patients' condition. None of the treated patients showed a negative response to the proposed program of medical rehabilitation and activation throughout the early postoperative period.
