https://doi.org/10.31174/SEND-NT2020-233VIII28-01
Abstract. We studied the effect of a 10-day drought and additional short-term temperature stress on changes in the structure and functional activity of photosystem II in two varieties of winter wheat of different resistance. It is shown that short-term high- temperature stress has a stronger effect on structural changes and a decrease in functional activity than drought. These changes in the resistant variety were less pronounced than in the unstable variety. During drought, a resistant variety forms nonspecific resistance to the action of high temperature, which is not observed in an unstable variety.
Keywords: Triticum aestivum L., winter wheat, photosystem II, low-temperature fluorescence, chlorophyll fluorescence induction.

Abstract. The flower morphology of some representatives in the order Asparagales is investigated in the article and the gynoecium zonality and the structure of septal nectary are studied. Our approach provides us with the possibility to differentiate the species and perhaps the genera after the location and presence of various vertical zones of the gynoecium and nectary particularly. The gynoecium structure in studied specied has differences in the lenght of the gynoecium and septal nectary zones, and also in the interrelation of all of these three types of vertical zonality.

https://doi.org/10.31174/SEND-NT2020-233VIII28-04
Abstract. A review of the literature revealed the disadvantages of the methods of mineral ores’ processing. To reduce the duration of the process in comparison with chloride leaching, we have developed a method of processing polymineral ores by leaching with saturated sulfate solutions. To study the features of sulfate leaching, it is interesting to use, first of all, the rotating disk method. This allowed us to study the kinetic patterns of sulfate leaching compared with the chloride leaching technology. It was found that in both cases the dissolution rate constants are close to each other. This indicates that in the process of sulphate leaching, the products of salting out crystallize in the extent of the solution and will not show inhibitory effect on the process. Therefore, the replacement of chloride leaching with sulfate does not reduce the speed of the process and will bring a number of advantages that determine the technological and instrumental design of galurgical processing of salt ores.
Keywords: polymineral ores, dissolution kinetics, rotating disk, sulphate leaching.

https://doi.org/10.31174/SEND-NT2020-233VIII28-12
Abstract. The first signs of disruption of the ultramicroscopic structure of the tricuspid valve of the white rat heart were detected after 2 weeks of experimental exposure to nalbuphin, which was manifested by changes in the thickness of the endothelial cell in its various parts, a decrease in the number of microvilli on the surface of endothelial cells and swollen cells. In the course of the experiment lasting 6 weeks, destructive changes increased, which led to the disorganization of the structure of the tricuspid heart valve of the white rat. Changes in the shape and size of endothelial cells, their loss of contact with the destroyed and homogenized basement membrane, the destruction of collagen and elastic fibers. The connective tissue exposed as a result of endothelial damage is infiltrated by blood lipids, indicating the onset of fatty degeneration.

Abstract. The article presents a study of antimicrobial action of copper citrate and silver citrate solution on pathogenic enterobacteria of Klebsiella Pneumoniae and Enterobacter Aerogenes species, which currently cause enterobacteriosis in bees. The solution of copper citrate and silver citrate has been shown to have a low antimicrobial effect on Gram-negative pathogens of the species Klebsiella pneumoniae and Enterobacter Aerogenes. It is promising to improve the disinfectant composition in order to increase activity and synergy between the components to enhance the bactericidal effect on pathogenic enterobacteria of bees.
