Individual psychomotor reactions in servicemen of special forces in the dynamics of performance of their service and combat missions have been studied. The data on personality psychological properties and functional processes in the nervous system of the servicemen in reference to different service length has been presented. The study has found that the reliability coefficient in the samples tended to decrease, but at all the studied stages, it was statistically significantly higher in the more experienced servicemen. There have been analyzed the most important parameters of responses to visual stimuli.

Objective: The aim of this study was to investigate the state and analyze the tendencies in development of voluntary health insurance in Bulgaria. Methods: The methods of system and critical analysis and statistical data processing were used to achieve the study objective. Results: Normative documents in the field of health insurance were examined and correlated to voluntary health insurance market in Bulgaria. Conclusion: Voluntary health insurance market in Bulgaria is poorly developed and there is no strategy for its expansion.

Results of the study of the conditions of detection of traces of marking agents added to industrial plastic explosives in air using preconcentration and subsequent analysis on a ECHO-V-IDVS modernized gas chromatograph with a polycapillary column, an ionization detector of a varying selectivity (IDVS), and atmospheric air as a carrier gas are presented. A significant effect of air humidity on the limits of detection for 4-nitrotoluene and 2,3-dimethyl-2,3-dinitrobutane is demonstrated; the highest IDVS sensitivity was observed at the humidity of the carrier gas less than 8.5 mg/m3. For the preconcentration of marking agents, concentrators based on Tenax adsorbent or those produced as metal wire grids coated with a stationary phase are most efficient. The limits of detection for vapors of marking agents in sampling 1 L of air to a concentrator are 22 pg/cm3 for 4-nitrotoluene and 0.1 pg/cm3 for 2,3-dimethyl-2,3-dinitrobutane. © 2015, Pleiades Publishing, Ltd.

The carrier leakage is one of the major factor that limits the performance of the UHF RFID reader. Compared to conventional method which uses vector modulator, this paper presents a passive carrier suppression method achieving low noise. Through experiments, the implemented carrier suppression circuit exhibits 40dB with transmission power of 28dBm; As a result, the sensitivity of reader improved 14dB when the BER of 10-5. The proposed method is successfully applied to the design of the UHF RFID reader. © 2014 IEEE.
