    The most important task facing the baking enterprise under market conditions is the production of bakery products with the best qualities that can be achieved from a particular batch of processed flour. In producing bakery products, wheat flour is the most volatile commodity. Then in order to obtain finished products with desired texture parameters the rheological properties of the semi-finished baking properties created from the raw materials and formulation products must be controlle

    Aspects of applying the method of chemical mutagenesis to develop cultivars of <i>Calendula officinalis</i> L.

    Get PDF
    Background. The need for continuous breeding practice to develop new varieties of Calendula officinalis L. is induced by the accumulation of low-grade morphotypes in the already existing cultivars as a result of crosspollination. Materials and methods. Seeds selected from high-yielding biotypes of cv. ‘Kalta’ were treated with various mutagens for 18 hours, using 1000 seeds for each option. The mutation rate in the M1 generation and seed quality were determined, and plant viability was assessed under field conditions. Plant height, number of branches, number of leaves, number of inflorescences per plant, inflorescence diameter, number of ray floret rows, and weight of one inflorescence were measured in the mass flowering phase. The yield of raw materials (fresh and air-dry biomass of inflorescences) was calculated for each harvest and for the total amount of all 7 harvests during the flowering period. Results. The mutagens DES0,05% and DMS0,08% turned out the most effective for developing new source material. None of the plants produced seeds after treatment with nitrosomethyl urea (NMU0.02% ), and only one plant produced seeds after treatment with NMU0.04% . As a result of a long-term breeding process (2009–2016), new varieties were developed on the basis of mutant generations M2–M3 : cvs. ‘Zolotoe more’ and ‘Rajskij sad’, both exceeding cv. ‘Kalta’ in the yield of inflorescences by 39 and 30%, seed yield by 48 and 49%, total extractives by 13.8 and 21.3%, and total flavonoids by 29.9% and 43.3%, respectively. Conclusion. New cultivars of C. officinalis, ‘Zolotoe more’ and ‘Rajskij sad’, were developed in accordance with the mutation breeding scheme that employed methods of chemical mutagenesis, with expanded selection of plants altered in their morphological characteristics, productivity and content of bioactive compounds in the first mutant generation and assessment of uniformity, distinctness and stability in the second and subsequent generations

    Background. The cultivars of Achillea millefolium L.: ‘Eney’ and ‘Millennium’ (Research Institute of Agriculture of Crimea), and ‘Vasyurinsky’ (North-Caucasian Branch of VILAR), were the objects of the ecological testing in 2018–2020 in Moscow Province.Methods. A nursery was established with planting material of vegetative origin. Phenological and morphometric parameters, indicators of raw matter productivity, and crop structure components were assessed in the phase of mass flowering.Results. For cv. ‘Vasyurinsky’, the start of growing and subsequent phenological phases occurred 14–25 days earlier than for ‘Eney’ and ‘Millennium’ whose growing season was 15–20 days longer. The plant height varied from 72 to 106 cm for cv. ‘Vasyurinsky’, 43 to 56 cm for ‘Eney’, and 38 to 42 cm for ‘Millenium’. The yield of fresh green biomass reached 8.8–10.3 t/ha for the Crimean cultivars, and 18.2 t/ha for ‘Vasyurinsky’. The latter exceeded cvs. ‘Eney’ and ‘Millenium’ in the yield of green biomass and air-dry matter (1.7–2.9 and 1.5–2.6 times, respectively). Essential oil content in ‘Eney’ was 4.74% of the absolute dry weight, being 1.6–3.5 times higher than in ‘Millenium’ (2.99%) and ‘Vasyurinsky’ (1.35%). Chamazulene content in the essential oil of the Crimean cultivars was 10–12 times higher, and the content of caryophyllene and germacrene D 2.5–3.1 times higher than in the essential oil of cv. ‘Vasyurinsky’.Conclusion. All the studied cultivars of A. millefolium can be recommended for commercial cultivation in Moscow Province

    Anisotropic flow fluctuations in hydro-inspired freeze-out model for relativistic heavy ion collisions

    Get PDF
    The LHC data on event-by-event harmonic flow coefficients measured in PbPb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted within the HYDJET++ model. To compare the model results with the experimental data the unfolding procedure is employed. The essentially dynamical origin of the flow fluctuations in hydro-inspired freeze-out approach has been established. It is shown that the simple modification of the model via introducing the distribution over spatial anisotropy parameters permits HYDJET++ to reproduce both elliptic and triangular flow fluctuations and related to it eccentricity fluctuations of the initial state at the LHC energy.Comment: 12 pages including 9 figures as EPS-files; prepared using LaTeX package for publication in the European Physical Journal

    Two-dimensional discrete wavelet analysis of multiparticle event topology in heavy ion collisions

    Full text link
    The event-by-event analysis of multiparticle production in high energy hadron and nuclei collisions can be performed using the discrete wavelet transformation. The ring-like and jet-like structures in two-dimensional angular histograms are well extracted by wavelet analysis. For the first time the method is applied to the jet-like events with background simulated by event generators, which are developed to describe nucleus-nucleus collisions at LHC energies. The jet positions are located quite well by the discrete wavelet transformation of angular particle distribution even in presence of strong background.Comment: 6 pages, 6 figure

    Breeding of medicinal and essential oil crops in VILAR: achievements and prospects

    Get PDF
    This review discusses the main methods of breeding material development, the current state, problems and prospects for medicinal and essential oil plants breeding. The relevance of this area has especially increased due to the sanctions, the resulting shortage of medicinal plants and their low quality, which does not meet the requirements of the pharmaceutical industry. To produce a stable plant raw material base, it is necessary to actively develop a breeding process to create new highly productive varieties of medicinal plants resistant to biotic and abiotic environments. In breeding with the use of modern molecular biological methods, related species and generic complexes of the All-Russian Research Institute of Medicinal and Aromatic Plants (VILAR) collection can be involved, where there is extensive original genetic material of medicinal, essential oil, rare and endangered species. In the breeding of medicinal and essential oil crops, traditional methods of individual and individual-family selection, polyploidy, chemical mutagenesis and a combination of methods to obtain original breeding material are still promising. VILAR has created more than 90 varieties of medicinal and essential oil crops, most of which have been approved for use throughout the Russian Federation

    This study appears urgent due to the need to create new jobs in the sport and recreation sector and to update the existing approach to vocational training in a micro-enterprise. This paper proposes an education project as a form of vocational training in such conditions. The authors aim to comprehend the current issues of pedagogical design for the transfer of experience within a micro-enterprise of the sport and recreation sector and to determine the conditions for effective educational interaction of micro-enterprise employees. This problem is addressed with a combination of the systematic approach and activity-based learning. This makes it possible to present the process of pedagogical design of vocational training in the conditions of a micro-enterprise as systematic activity of individuals in developing the professional competencies of a sport and recreation worker. The authors used theoretical and empirical methods. The theoretical methods were analysis of the psychological, pedagogical, sociological, scientific-methodological and specialized literature on the studied problem; the systematic approach to the definition of the problem and the formation of the research terminology; and analysis of the legal acts. The empirical methods were pedagogical observation; study and generalization of pedagogical experience; pedagogical design; questioning; conversation; interview; performance analysis; and expert evaluation method and integration of expert opinions. © 2018 Authors
