Fungal microbiota of biodamages of various polymeric materials.

Data on microbial fouling of various synthetic polymer materials, including those used in space technology, are summarized. It has been established that the dominant groups of microbiota of polymer fouling are the genera of mitosporous fungi Aspergillus, Penicillium, Alternaria, Trichoderma. The enzymatic properties of fungal strains from the collection of microbial cultures of the Microbial Depository Center of the National Academy of Sciences of Armenia were studied.

[Forensic chemical and chemicotoxicological examination of ricin poisoning by the HPLC-MS/MS method].

Is to suggest the method of ricin determination in biological liquids during forensic medical and chemicotoxicological examination. This research describes the optimal conditions of sample processing of biological liquids, allowing to extract the components (ricinine and ricinoleic acid) of castor seeds. The recommended analysis conditions allow to perform research for 15 minutes by high resolution mass spectrometry method combined with high-value liquid chromatography on a chromato-mass spectrometer to detect ricinine and ricinoleic acid.

The modulating impact of illumination and background radiation on 8 Hz-induced infrasound effect on physicochemical properties of physiolagical solution.

At present, when the level of background ionizing radiation is increasing in a number of world locations, the problem of the study of biological effect of high background radiation becomes one of the extremely important global problems in modern life sciences. The modern research in biophysics proved that water is a most essential target, through which the biological effects of ionizing and non-ionizing radiations are realized. Therefore, there is no doubt about the strong dependency of non-ionizing radiation-induced effect on the level of background radiation.

The density-dependency of dark- and low-background radiation effects on water and water solution properties.

The effects of dark -(Ev=0 lux) and low-background radiation (BGR), where R<1μRongen/h, on physicochemical properties (specific electrical conductivity, heat fusion, hydrogen peroxide (H2O2), and oxygen contents) of distilled water (DW) and physiological solution (PS) at 4°C and 18°C were studied. The incubation of DW and PS samples in dark and in low BGR (under dark) medium at 4°C and 18°C brings to changes of their physicochemical properties compared with DW and PS samples incubated in light and normal BGR condition (Ev=500-550 lux and R=17 μRoentgen/h). The observed changes of DW and PS properties depended on their initial temperature, density and ionic composition.

The non thermal effect of weak intensity millimeter waves on physicochemical properties of water and water solutions.

The comparative study of the effects of 5.8 mW/cm(2) Millimeter Waves (MMW) and near Infrared (IR) irradiation on thermal properties, specific adsorption rate (SAR), specific electrical conductivity (SEC) and hydrogen peroxide (H(2)O(2)) content of distilled water (DW), and physiological solutions (PS) was performed. The thermal effect of MMW irradiation appeared only after the first minute of irradiation, while the IR heating started from the first minute of irradiation.
