Screening of the bactericidal action of phytocompositions and their components. Materials and methods: standard methods of microbiology used Results: Three phytocompositions based on Filipendula ulmaria (L.) Maxim. have been created, allowing to obtain improved organoleptic properties, reduce the number of deficient components, and expand the range of antioxidant, anti-inflammatory and anti-ulcerogenic compositions based on plant materials of the Republic of Belarus. Compositions are obtained by simple mixing of air-dried plant components in the desired weight ratio. Brew in boiling water, keep for several minutes and consume in hot or chilled form. The bactericidal action of three phytocompositions and their plant components was screened using five cultures of test microorganisms as an example. It was found that the studied aqueous extracts had a different degree of bactericidal action. The bactericidal action was most pronounced in relation to the culture of Bacillus subtilis. Sarcina lutea was the most resistant colony to the bactericidal action of the plant extracts. The maximum bactericidal action of all the studied samples was established for Filipendula ulmaria (L.) Maxim. Conclusion. Three phytocompositions of Filipendula ulmaria (L.) Maxim. have been created by the authors of the article. Improved organoleptic properties, decrease the number of scarce plant components, increase the number of phytocompositions that have an antioxidant, anti-inflammatory and antiulcerogenic effect with plants which grow in Belarus. Bactericidal action of phytocompositions and their components has been screned by using five kinds of test microorganisms

Screening of the bactericidal action of phytocompositions and their components. Materials and methods: standard methods of microbiology used Results: Three phytocompositions based on Filipendula ulmaria (L.) Maxim. have been created, allowing to obtain improved organoleptic properties, reduce the number of deficient components, and expand the range of antioxidant, anti-inflammatory and anti-ulcerogenic compositions based on plant materials of the Republic of Belarus. Compositions are obtained by simple mixing of air-dried plant components in the desired weight ratio. Brew in boiling water, keep for several minutes and consume in hot or chilled form. The bactericidal action of three phytocompositions and their plant components was screened using five cultures of test microorganisms as an example. It was found that the studied aqueous extracts had a dif-ferent degree of bactericidal action. The bactericidal action was most pronounced in relation to the culture of Bacillus subtilis. Sarcina lutea was the most resistant colony to the bactericidal action of the plant extracts. The maximum bactericidal action of all the studied samples was established for Filipendula ulmaria (L.) Maxim. Conclusion. Three phytocompositions of Filipendula ulmaria (L.) Maxim. have been created by the authors of the article. Improved organoleptic properties, decrease the number of scarce plant components, increase the number of phytocompositions that have an antioxidant, anti-inflammatory and antiulcer-ogenic effect with plants which grow in Belarus. Bactericidal action of phytocompositions and their com-ponents has been screned by using five kinds of test microorganisms

    Parafermionic theory with the symmetry Z_5

    A parafermionic conformal theory with the symmetry Z_5 is constructed, based on the second solution of Fateev-Zamolodchikov for the corresponding parafermionic chiral algebra. The primary operators of the theory, which are the singlet, doublet 1, doublet 2, and disorder operators, are found to be accommodated by the weight lattice of the classical Lie algebra B_2. The finite Kac tables for unitary theories are defined and the formula for the conformal dimensions of primary operators is given.Comment: 98 pages, 21 eps figure

    Estimation of the possibility of using autochton species for landscaping urbanized spaces in the territory of Belarus

    Objective of the research. Based on the analysis of the composition of highly decorative representatives of the flora of Belarus, growing in places with a high level of anthropogenic impact, to assess the possibility of using autochthonous species for planting greenery in urban areas. Materials and methods. Standard methods of analytical chemistry. Results. The article presents the main results of ecological and botanical research on changes in phytocenotic parameters and aesthetics of the vegetation cover during the growing season. Highly decorative plants were found most of all among eutrophic eumezophytes (Leucanthemum vulgare Lam., Primula veris L., Agrimonia eupatoria L., etc.) and xeromesophytes (Centaurea jacea L., Origanum vulgare L., etc.). Most sites show the presence of species such as Achillea millefolium L., Centaurea jacea L., Knautia arvensis (L.) Coult., Plantago lanceolata L., Daucus carota L., Potentilla erecta (L.) Raeusch., Trifolium pratense L., Viscaria vulgaris Bernh., Echium vulgare L., Dianthus deltoides L., Leucanthemum vulgare Lam., Cota tinctoria (L.) J. Gay., Betonica officinalis L., Origanum vulgare L. were found in areas with less intense anthropogenic load. Conclusion. The composition of soils, pollution and highly ornamental species of the autochthonous flora of Belarus in areas with increased anthropogenic significance were analyzed.ЦСль Ρ€Π°Π±ΠΎΡ‚Ρ‹.

    Non-additive fusion, Hubbard models and non-locality

    Full text link
    In the framework of quantum groups and additive R-matrices, the fusion procedure allows to construct higher-dimensional solutions of the Yang-Baxter equation. These solutions lead to integrable one-dimensional spin-chain Hamiltonians. Here fusion is shown to generalize naturally to non-additive R-matrices, which therefore do not have a quantum group symmetry. This method is then applied to the generalized Hubbard models. Although the resulting integrable models are not as simple as the starting ones, the general structure is that of two spin-(s times s') sl(2) models coupled at the free-fermion point. An important issue is the probable lack of regular points which give local Hamiltonians. This problem is related to the existence of second order zeroes in the unitarity equation, and arises for the XX models of higher spins, the building blocks of the Hubbard models. A possible connection between some Lax operators L and R-matrices is noted.Comment: 14 pages, Latex. A remark added in section 2, four typos correcte

    Random Matrix Theory and higher genus integrability: the quantum chiral Potts model

    Full text link
    We perform a Random Matrix Theory (RMT) analysis of the quantum four-state chiral Potts chain for different sizes of the chain up to size L=8. Our analysis gives clear evidence of a Gaussian Orthogonal Ensemble statistics, suggesting the existence of a generalized time-reversal invariance. Furthermore a change from the (generic) GOE distribution to a Poisson distribution occurs when the integrability conditions are met. The chiral Potts model is known to correspond to a (star-triangle) integrability associated with curves of genus higher than zero or one. Therefore, the RMT analysis can also be seen as a detector of ``higher genus integrability''.Comment: 23 pages and 10 figure
