Laser monitor for non-destructive testing of materials and processes shielded by intensive background lighting.

A single-pulse imaging laser projection system (laser monitor) is proposed for real-time monitoring high-speed processes shielded by the intensive background lighting. The brightness temperature of the lighting can reach thousands or even tens of thousands of degrees, which makes it difficult to observe the processes with the naked eye. The estimates of limiting temperatures show that the use of the proposed instrument allows to view the objects when the equivalent brightness temperature of the background lighting is up to 45,000 K.

Modeling technique of capacitive discharge pumping of metal vapor lasers for electrode capacitance optimization.

To estimate optimum gas discharge tube (GDT) electrode capacitance of metal vapor lasers (MVLs) pumped by a longitudinal capacitive discharge, we offer to use series connection of capacitors to the electrodes of a conventionally pumped GDT with inner electrodes. It has been demonstrated that the maximum output power in CuBr lasers is obtained when the capacitances of high-voltage and ground electrodes are equal. When using a model circuit an average output power reaches 12 W that suggests the possibility of generating high average output power (>10 W) in MVLs pumped using a capacitive discharge.

[The use of neoadjuvant intra-arterial polychemotherapy in the treatment of cancer of the genitalia].

Results are submitted of employment of intraarterial superselective polychemotherapy in the treatment of malignant tumors of female genital organs in 106 patients; of these, forty individuals presented with carcinoma of the neck of the womb, 33 with tumours of the trophoblast, 18 had carcinoma of the ovaries, and 15 carcinoma of the body of the womb. A clinical analysis was done of the results obtained as were clinical-morphological correspondences (there has been studied a therapeutic pathomorphosis of the tumours) depending on the disease stage, individual schemes of polychemotherapy. The greatest benefit from the above treatment occurred in proliferative and invasive vascular mole and choriocarcinoma; patients with carcinoma of the neck and body of the womb derived less benefit, those with carcinoma of the ovaries experienced the least therapeutic effect.

[Structure of working conditions in occupation having privileges according to the List #1 and #2].

The scientists studied work conditions of workers at KAMAZ plants. The studies covered the workers which are assigned to Registers 1 and 2 providing preferential pensions for hazardous and hard work conditions. Although being empirically formed, the Registers include workplaces which are similar in some characters.
