    Introduction. The issues of creating, preserving and improving the quality of green areas are relevant not only for the municipality — the city of Barnaul, but also for each urban settlement of the Russian Federation, village and settlement.Methodology. To identify numerous shortcomings in the management, a statistical analysis of the main indicators of the development of the improvement sector, the main opinions of «experts», was carried out. In order to find ways out to ensure the comfort of living for each resident of the city, a theoretical generalization is used.Results. The main geoecological characteristics of the municipality — the city of Barnaul – are described. It reflects not only the achievements of local governments in this area, but also highlights the main problem-the lack of a unified concept of landscaping. To predict the development of the city and the formation of a unified approach to landscaping, the main measures are proposed that will allow creating an up-to-date, and most importantly, allowing each resident to comfortably exist, a model for managing the field of landscaping.Analysis and discussion. The forecast estimate for the municipality — the city of Barnaul from the proposed measures for rational use of natural resources is given.Conclusions. The application of these results is not only possible, but it is also necessary to take into account the local self-government bodies when managing the geoecological processes of each city of the Russian Federation in order to achieve an optimal standard of living for the population

    Objective: to analyze the impact of the externalities of the sanctions pressure policy on small and medium-sized enterprises and to develop specific proposals that allow them to adapt to the conditions of uncertainty.Methods: general scientific methods of systemic, structural and comparative analysis, as well as specific scientific methods (static and graphical analysis, expert assessments).Results: the analysis was carried out of the externalities of the sanctions pressure policy, which significantly affected the activities of the Russian small and medium-sized enterprises. Among the key factors studied are the disruption of logistics chains, reduction of the customer base, restrictions on monetary transactions, blocking of digital platforms, etc. The special role of this sector in eliminating the imbalances of the country’s economy in a difficult geopolitical situation and economic instability is outlined. It is proposed to investigate ways of adapting small businesses to new economic conditions, taking into account the systematic classification of enterprises in the SME sector. The forecast trends in the development of small and medium-sized firms for the near future are formulated. Based on the analysis of externalities, the author suggests measures to increase the adaptability of enterprises in the studied segment of the economy, which can be used by both representatives of the business community and government agencies.Scientific novelty: the division of firms into three categories (“kids”, “genetic dwarfs”, “transformers”) and three subgroups (“travelers”, “reorganizers”, “imago”) is proposed; their key functions and ways of adaptation characteristic of each category of enterprises are identified, which made it possible to develop recommendations on improving the adaptability of small and medium-sized enterprises, taking into account their characteristics.Practical significance:  the main provisions and conclusions of the article can be used in the educational process of educational institutions; in scientifi activities for the development of academic competencies on the functioning of small and medium-sized enterprises; in the work of organizations that make up the infrastructure for the development and support of SMEs; they also contribute to the study of ways and strategies for the entrepreneurship adaptation under exogenous shocks

    Get PDF
    One of the mainstreams in linguistics at the end of the XXth - beginning of the XXIst century is a linguocultural modeling of linguistic consciousness and communicative behaviour, i.e. the creation of a certain linguocultural archetype. By itself, the term "linguocultural archetype" is an interdisciplinary concept of cultural linguistics, linguistic conceptology and linguistic personology. The authors of the paper consider a linguocultural archetype, on the one hand, as a set of indicators, which make it possible to find a recognizable image of some individual, and on the other hand, reveal the features typical for a social or ethnic group, which is a binding basis for the archetype. The linguocultural archetypes presented in the paper are considered as typified individuals from a certain ethno-social group; they are recognisable by their characteristic features of verbal and non-verbal behaviour and value orientation in the society. The paper deals with conceptual, figurative, value and associative features of British linguocultural archetypes such as "English policeman", and "knocker up".The important indicators of linguocultural archetypes in cognitive consciousness of people are recurrence, associativity and textuality. The recognisability of the linguocultural archetypes "English policeman" and "knocker up" is stipulated by the mentioning of these professions in films, works of writers and artists, as well as in mass media materials

    © Published under licence by IOP Publishing Ltd. The paper deals with the problem of determining the mechanical macroparameters of the porous material in case of knowing the information about it's structure. Fabric tensor and porosity was used to describe structure of the material. Experimental study presented. In research two-component liquid polyurethane plastics of cold curing Lasilcast (Lc-12) was used. Then samples was scanned on computer tomography. Resulting data was analyzed. Regular subvolume was cut out after analyses. Then mechanical tests was performed. As a result we get information about fabric tensor, porosity, Young's modulus and Poisson ratio of the sample. In the abstract presented results for some samples. Taking into account the law of porosity variation, we considered the problem of evaluating the mechanical macro parameters depending on the nature of the porous structure. To evaluate the macroparameters, we built the dependence of the Young's modules and Poisson ratio of the material on the rotation angle α and the pore ellipticity parameter λ. The sensitivity of the deformations to the elastic constants was also estimated

    This paper presents the results of assessing the reproductive seed quality of Clarkia amoena (Lehm) A. Nelson & J.F. Macbr) seeds during storage under laboratory conditions (temperature 20–22°C). The seeds were stored in paper bags for eight years. The authors selected seed samples from pods of varying degrees of maturity (open and closed) and different positions on the mother plant (branches of other orders). The authors set up three groups based on their location on the mother plant: 1) Sixty-four seed samples were formed on the main stem (firstorder branches); 2) Sixty-four seed samples were created on second-order branches; 3) Sixty-four seed samples were created on third-order branches and two groups based on fruit maturity: open and closed pods. In total, 192 seed samples were evaluated. Seed quality assessment was conducted annually in April, following GOST 24933.081 standards for flower crop seeds. The initial laboratory germination of seeds ranged from 69% for samples taken from closed pods on third-order branches to 97% for samples taken from open pods on the main stem. It decreased with an increase in the seed storage period according to a linear regression equation: Y = 7.673–0.064X, where Y is the storage duration, and X is the seed germination rate. Over eight years of storage, the 1000-seed mass decreased by 37.2% for samples from the main stem's open pods and 30.3% for samples from closed pods, by 43.6% and 46.8% for second-order branches, and by 46.1% and 50.9% for third-order extensions, respectively. On average, the 1000-seed mass decreased by 0.2 g for all samples over eight years of storage. Regression and correlation analyses (Pearson's coefficient) revealed significant negative relationships between storage duration and seed germination energy (r = –0.849), germination rate (r = –0.853), and 1000-seed mass (r = –0.790). A strong positive correlation was observed between seed mass and viability (r = 0.886). Over eight years of storage, seeds from the main stem lost their germination rate to 18–23%, significantly lower than the initial rate. In contrast, second-order branch seeds decreased by half, and roots from third-order branches completely lost viability. A multidimensional model of the interaction of factors—storage duration and branch order—on seed viability under ex-situ conditions was constructed, demonstrating that the overall viability of Clarkia amoena seeds is maintained for 4–5 years.Представлены результаты оценки репродуктивных качеств семян Clarkia amoena Lehm.) A. Nelson & J.F. Macbr.) при хранении в лабораторных условиях (температура 20–22 о С). Семена хранились в лабораторном шкафу в бумажных пакетах в течение 8 лет. Образцы семян были выделены из коробочек разной степени зрелости (открытых и закрытых) и разного местоположения на материнском растении (побеги разных порядков). Было выделено три группы по местоположению на материнском растении: 1) 64 образца семян, сформированных на главном стебле (побег первого порядка); 2) 64 образца семян, сформированных на побегах второго порядка; 3) 64 образца семян, сформированных на побегах третьего порядка и две группы по степени зрелости плодов: открытые и закрытые коробочки. Всего – 192 образца семян. Определение качества семян проводили ежегодно, в апреле, согласно ГОСТ 24933.0-81 на семена цветочных культур. Исходная лабораторная всхожесть семян варьировала от 69 % у образцов семян, выделенных из закрытых коробочек с побегов третьего порядка, до 97 % у образцов семян, взятых из открытых коробочек главного стебля, и уменьшалась с увеличением периода хранения семян при линейном уравнении регрессии У = 7,673–0,064 х, где У – срок хранения, Х – всхожесть семян. Масса 1000 семян за 8 лет хранения снизилась у образцов с главного стебля на 37,2 % из открытых коробочек и на 30,3% – из закрытых; с побегов второго порядка – на 43,6 и 46,8; с побегов третьего порядка – на 46,1 и 50,9 % соответственно. В среднем для всех образцов, масса 1000 семян за 8 лет хранения уменьшилась на 0,2 г. В результате проведенного регрессионного и корреляционного анализа (коэффициент Пирсона) были определены достоверные отрицательные зависимости влияния срока хранения на энергию прорастания семян (r = – 0,849), всхожесть (r = – 0,853) и массу 1000 семян (r = – 0,790). Сильная положительная корреляция наблюдалась между массой и жизнеспособностью семян (r = 0,886). За 8 лет хранения семена с главного стебля снизили всхожесть до 18–23 %, что на 78–74 % ниже первоначальной, с побегов второго порядка – еще вдвое, а семена с побегов третьего порядка полностью утратили жизнеспособность. Была построена многомерная модель взаимодействия факторов: срока хранения и порядка побега на жизнеспособность семян в условиях ex-situ, которая наглядно подтвердила, что жизнеспособность семян Clarkia amoena сохраняется в течение 4–5 лет

    Clarkia amoena (Lehm.) A. Nelson & J. F. Macbr., a valuable outdoor ornamental crop, was grown south of Western Siberia (GPS coordinates: 55.0312880° N, 82.9903190° E). The work aimed to study the features of the reproductive biology of a new variety of clarkia Malinovaya chasha selected by the Novosibirsk State Agrarian University and to assess the topographic (quantity and quality of seeds from shoots of different orders), matural (various degrees of fruit ripening) and ecological (dependence of productive and sowing attributes on the main climatic factors in periods flowering and fertilisation) variability of economically valuable traits. The study used the method of multiple regression, correlation, and cluster analyses of experimental data. Fruits and seeds of a new variety of Clarkia Raspberry Cup, which were set during free pollination, formed at different flowering times and on shoots of various locations on the main stem, differed in quantity, weight, size and sowing qualities. Analysis of seed quality indicators (weight of 1000 seeds, germination energy, germination) revealed a multiple regression dependence on the heat supply of the periods of fertilisation and seed formation. The importance of the seeds of the clarkia variety Raspberry bowl by weight of 1000 pcs., formed in different periods, varied from 0.327 g in the period unfavourable for seed formation - from August 20 to September 10 - to 0.6 g in the favourable period - the first ten days of August. A significant dependence of the mass of 1000 pcs. Based on the average daily air temperature and the sum of active temperatures above 15 °C, the correlation coefficient (r) ranged from 0.976 to 0.978. The conducted studies have revealed several features of the formation of the crop structure of a new variety of Clarkia, depending on topographic, matural, and ecological variability. The actual seed productivity of the clarkia variety Raspberry bowl in the south of Western Siberia is, on average, 50% of the potential. From one varietal plant in the south of Western Siberia, 3.026 g of seeds are obtained (on average, over three years of research). The established relationships between the quality of seed material and the main climatic factors make it possible to control and, to a certain extent, predict the seed yield of the new variety Clarkia amoena Raspberry bowl in the sharply continental climatic conditions of the south of Western Siberia.Кларкия прелестная (Clarkia amoena (Lehm.) A. Nelson & J. F. Macbr.), являющаяся ценной декоративной культурой открытого грунта, выращивалась в климатических условиях юга Западной Сибири (координаты GPS: 55.0312880° с.ш., 82.9903190° в.д.). Целью работы являлось изучение особенностей репродуктивной биологии нового сорта кларкии Малиновая чаша селекции Новосибирского ГАУ и оценка топографической (количество и качество семян с побегов разных порядков), матуральной (разная степень созревания плодов) и экологической (зависимость продуктивных и посевных качеств от основных климатических факторов в периоды цветения и оплодотворения) изменчивости хозяйственно-ценных признаков. В исследовании использовали метод множественной регрессии, корреляционный и кластерный анализы экспериментальных данных. Плоды и семена нового сорта кларкии Малиновая чаша, завязавшиеся при свободном опылении, сформированные в разные сроки цветения и на разных по местоположению на главном стебле побегах, различались по количеству, массе, крупности и посевным качествам. Анализ показателей качества семян (масса 1000 шт., энергия прорастания, всхожесть) выявил множественную регрессионную зависимость от теплообеспеченности периодов оплодотворения и формирования семян. Полновесность семян кларкии сорта Малиновая чаша по массе 1000 шт., сформировавшихся в разные периоды, варьировала от 0,327 г в неблагоприятный для формирования семян период – с 20 августа по 10 сентября – до 0,6 г в благоприятный период – первую декаду августа. Была выявлена значительная зависимость массы 1000 шт. семян от среднесуточной температуры воздуха и суммы активных температур выше 15 °С, коэффициент корреляции (r) колебался в пределах 0,976–0,978. Проведенные исследования выявили ряд особенностей формирования структуры урожая нового сорта кларкии в зависимости от топографической, матуральной, экологической изменчивости. Реальная семенная продуктивность сорта кларкии Малиновая чаша в условиях юга Западной Сибири в среднем составляет 50 % от потенциальной. С одного сортового растения в условиях юга Западной Сибири получается 3,026 г семян (в среднем за 3 года исследований). Установленные взаимосвязи между качеством семенного материала и основными климатическими факторами позволяют контролировать и в определенной мере прогнозировать урожайность семян нового сорта Clarkia amoena Малиновая чаша в резко-континентальных климатических условиях юга Западной Сибири
