The Effect of Personal Health on the Formation of Human Capital: a Metasystem Approach

In article the problem of influence of the personality's health on formation of the human capital is considered. Authors have conducted theoretical researches of the existing knowledge of the human capital and justifications of influence of the personality's health on its formation are given. On the basis of the carried-out analysis it is established that now the personality's health is a significant factor of efficiency of any kind of activity and important quality of the personality, therefore, it can be considered as a factor of formation of the human capital. According to it need of determination of criteria, the indicators of health of the personality influencing formation and development of the human capital was designated

Random raman fiber laser based on a twin-core fiber with FBGs inscribed by femtosecond radiation

Narrowband Raman lasing in a polarization-maintaining two-core fiber (TCF) is demonstrated. Femtosecond point-by-point inscription of fiber Bragg gratings (FBGs) in individual cores produces a half-open cavity with random distributed feedback. The laser linewidth in the cavity with a single FBG inscribed in one core of the TCF reduced by ∼2 times with respect to the cavity with a fiber loop mirror. It is shown that the inscription of two FBGs in different cores leads to the formation of a Michelson-type interferometer, leading to the modulation of generation spectra near threshold. This technique offers new possibilities for spectral filtering or multi-wavelength generation

SiC- and Ti3SiC2-Based Ceramics Synthesis by Spark Plasma Sintering of Preceramic Paper

This paper is devoted to proposing a new approach to the synthesis of SiC- and Ti3SiC2-based ceramics by using of preceramic paper as a feedstock. A preceramic paper with SiC and Ti3SiC2 powder fillers were sintered by spark plasma sintering (SPS) method for holding time 10 minutes under pressure 20-100 MPa. The temperature for the sintering of SiC- and Ti3SiC2-filled paper was 2073-2373 K and 1373-1473 K respectively. The influence of sintering parameters on the materials microstructure was analyzed by scanning electron microscopy. It was revealed that with an increase in pressure from 20 to 100 MPa, the microstructure of the materials becomes denser. It agrees with the results of measuring the density of the sintering materials by the hydrostatic weighting. The determination of Young`s modulus by the acoustic method demonstrates that with the increase of the applied pressure during SPS, Young’s modulus of the synthesized SiC- and Ti3SiC2-ceramics increase

Influence of preceramic paper composition on microstructure and mechanical properties of spark plasma sintered Ti3SiC2-based composites

AbstractThis paper describes the effect of preceramic paper composition on microstructure and mechanical properties of Ti3SiC2-based composites. The preceramic paper with Ti3SiC2-powder filler and different content (from 10 to 40 wt.%) of organic component (cellulose) was prepared. The composites were obtained by spark plasma sintering (SPS) at 50 MPa pressure for 10 min holding time. The sintering temperature was 1473 K. The influence of organic content on microstructure, phase composition, and flexural strength of the sintered materials was analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and mechanical testing, respectively. It was revealed that the microstructure of the sintered materials became more porous with increasing of cellulose content in the paper. XRD analysis showed the presence of Ti3SiC2, TiC and TiSi2 phases in the sintered samples while the content of the Ti3SiC2 phase increase with decreasing of the organic content. The flexural strength changes from 100 (40 wt.%) to 300 MPa (10 wt.% organic binder) that is caused by porosity of the composites

Raman fiber laser based on dual-core fiber with fiber Bragg grating inscribed by femtosecond radiation

Application of femtosecond point-by-point inscription technique make it possible to form fiber Bragg gratings (FBGs) in different cores of multicore fibers as mirrors of laser cavity. In this paper, we present various configurations of Raman laser based on dual-core fiber. Due to the use of the inscribed FBG in the cavity of dual-core fiber, lasing threshold is reduced and the output power stability is increased, comparing to existing schemes
