Abstract Presently, there is an intensive search for fungal endophytes to be used in agriculture the protection and condition improvement of plants medicine. We screened presence raspberry, which occurs naturally Białowieża Forest. The isolates representative each morphotype were analysed using molecular markers ITS1 ITS2. In total, we found 34 taxa endophytic fungi. majority potential pathogen...
The genus Thalictrum species (Ranunculaceae) are of interest for study as medicinal plants that promising expanding the gene pool and treating socially significant diseases. data analysis more than 100 geobotanical descriptions obtained in 2010-2017 were used to coenotic complexes minus simplex growing Tomsk region determine their ecological-coenotic confinement. aim our research was region, di...
The aim. Today we are witnessing the actualization of research on plant sources for pharmaceutical and food industries. It is caused by a significant increase in demand these types resources. Therefore, variety case studies aimed at identifying characteristics resources, becoming more actual too. In accordance with this need, present work aims to identify relationship between content flavonoids...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
Contemporaneous plant communities may retain a mark of past disturbances in their ecological patterns. However, unraveling the history of disturbance on natural systems at a large scale is often unfeasible, due to the complexity of the factors involved and lack of historical data. Here we aim at demonstrating how comparing observed spatial structure of tree assemblages with that expected in a h...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...

Abstract Light gray forest soils (Eutric Retisols (Loamic, Cutanic, Ochric)) were studied under a 20–25-yr-old fallow at the stage of overgrowing by meadow vegetation, pine, and birch. The area plot was confined to one element topography, without morphological evidences erosion processes, with relatively homogenous soil texture. To assess influence vegetation on formation organic matter (SOM), ...
