Microstructure of epitaxial layers of doped GaAs and its crystal growth dynamics on single crystal GaAs substrate were studied by Raman microspectroscopy with a Dilor OMARS instrument equipped with a 1024 photodiode multichannel detector and a ion-argon laser Spectra-Physics emitting at 514.5 nm.The spatial resolution of this technique, less than 1 μm2, allows the recording of Raman spectra at several spots in function of thickness, from the substrate to the outer deposit, including areas around the interface (Fig.l).The high anisotropy of the LO and TO Raman bands is indicative of the orientation of the epitaxial layer as well as of the structural modification in the deposit and in the substrate at the interface.With Sn doped, the epitaxial layer also presents plasmon in Raman scattering. This fact is already very well known, but we additionally observed that its frequency increases with the thickness of the deposit. For a sample with electron density 1020 cm-3, the plasmon L+ appears at 930 and 790 cm-1 near the outer surface.

Abiotic And Biotic Factors

Pike-perch is an invader for the water basins of Central Kazakhstan. These species have stable self-reproductive populations in the regional waters. Back calculation method was used to investigate pike-perch growth rates in reservoirs of K. Satpayev’s channel. For comparison, the data from the other water bodies (Vyacheslavsky and Sherubay-Nurinsky water reservoirs) were used, as well as literature data. Pike-perch species from the investigated waters don’t show high growth rates. The populations from the reservoirs of K. Satpayev’s channel have quite similar growth rates with populations from the Amur river, from a number of reservoirs in the Volga river basin and from the reservoir in Spain. Sexual differences in growth have not been observed. Evaluating possible influence of various abiotic and biotic factors on the growth rate of pike-perch in the reservoirs of K. Satpayev’s channel was carried out. It has been stated that the availability of trophic resources cannot play a key role in growth dynamics because of their high abundance. Morphology of water bodies also does not play a role, as well as chromaticity, turbidity and other optical water indicators. It can be supposed that the main factor influencing growth of pike perch is the habitat’s temperature. This factor hardly ever approaches optimal values for the species in reservoirs of K. Satpaev’s channel. The possible influence of fishing selectivity on pike-perch growth rates was also evaluated. Currently, there has been imposed a moratorium on pike-perch catch. However, pike-perch is found in by-catches and in catches of amateur fishermen. It should be said that such seizures have an insignificant role in the dynamics of growth rates.

Urgent Task

Relevance: Inflammatory-destructive periodontal diseases are the most complicated and became the main cause of tooth loss in adult population. Herbal medicines have a variety of pharmacological properties, so the development and introduction of new forms for the treatment of inflammatory periodontal diseases is an urgent task today.Purpose – experimental evaluation of effectiveness of the use of herbal medicines “Tonzinal” and “CM-1” in relation to the priority periodontal pathogenes.Materials and methods: in experimental studies, the basis for the experiment was the system for the cultivation of microorganisms in real time – the Revers-Spinner RTS-1 bioreactor. With the priority strains of periodontitis pathogens, the study of the growth dynamics of the culture was carried out in several parallels.Results: herbal medicines “CM-1” and “Tonsinal” has a multilateral therapeutic effect, exerting a diverse influence on the key stages of development of such bacterial populations as Aggregatibacter actinomycetemcomitans, Streptococcus constellatus, Candida albicans.Conclusion: tan integrated approach in the treatment of patients with inflammatory periodontal diseases is promising and will contribute to a more prolonged remission and increase the effectiveness of treatment.
