Later it was found that the active substance of the bacterial extract was a low-molecular (16.9 kDa) thermostable protein named Microbial Factor 3 (MF3). The gene of MF3 was cloned and sequenced. The amino acid sequence of MF3 revealed a high level of homology with peptidyl-prolyl cis-trans isomerases of FKBP-type. The ability of MF3 to cause nonspecific resistance in plants to plant pathogens was shown on the following plant - pathogen pairs. The ability to induce resistance in plants to viral infections. Tobacco leaves treated with low concentration of MF3 solutions were not infected by TMV and potato virus Y (YVP). Resistance to TMV and YVP infection was kept at least within 11 and 4 weeks, correspondingly. MF3 did not directly affect TMV but decrea...

Remote diagnostics of mineral oil on water surface necessarily includes fast mapping of the spill, oil type recognition, and estimation of thickness of oil spilled on water surface. Since very thin oil films spreading on water surface affect the character of aquatic and atmospheric processes, it becomes important to measure film thickness with micrometer accuracy. Nowadays, the only sensor which has the ability to positively identify and quantify oil films is the laser fluorosensor. Currently LIDAR techniques for oil spill monitoring are based on detection of laser induced oil fluorescence and backscattered water Raman signal. The technique of water Raman suppression by an oil spill is used for oil film thickness measurement and evaluation of the total oil volume spread on water surface. This work describes spectral properties of mineral oils (ranging from sub-micrometer layer on water surface up to optically thick layer) excited by laser radiation under controlled laboratory conditions. Three types of LIDAR systems operating at wavelengths of 308, 337 and 355 nm were tested experimentally. The measurements were performed for several crude and refined mineral oils as pure substances and spilled into a large water container.

Unfortunately there are many clear systematical disagreements both in shape and magnitude between data obtained in different experiments. Very shortly most of them can be described as following: as a rule reaction cross sections obtained in experiments using quasimonoenergetic annihilation photons in comparison with those obtained in experiments using bremsstrahlung look much smoother. The reasons for that were investigated in detail on the basis of all (final and intermediate) results of some typical experiments with annihilation photons. It was shown that photonuclear reaction cross sections obtained with annihilation photons are strongly over-smoothed and the real energy resolution is several (3–4) times worse than estimated one (calculated p...
