Работа направлена на изучение околосолнечных и околоземных астероидов и их связей. Исследования в области изучения околосолнечных астероидов важны для развития эволюционной теории Солнечной системы. На данный момент отсутствует теория динамики солнечного ветра и изучение поведения околосолнечных и околоземных астеро- идов вносит свой вклад в построение данной теории. Принимается, что околосолнечные астероиды можно исследовать как околоземные астероиды, если они находятся в непосредственной близости от Солнца, имеют малые размеры и малые перигелийные расстояния. В работе применяется созданная авторами имитационная модель динамики около- солнечных астероидов с малыми перигелийными расстояниями. Рассматривается пополнение пылевых образований и колец, существующих во внутренней части Солнечной системы. Изучаются распределения по орбитальным пара- метрам – построены зависимости эксцентриситета от большой полуоси орбиты и наклона орбиты от большой полуоси орбиты для NEA. Построены и проанализированы температурные зависимости - зависимость изотермической и сфе- рической температуры и субсолнечной температуры от большой полуоси орбиты для NEA. Получены зависимости по цветовым индексам и проведен их анализ. Результаты данной работы полезны для понимания физики динамических процессов как Солнечной системы, так и, как следствие, вносят вклад в исследование эволюции систем экзопланет.
The work is aimed at studying near-solar and near-Earth asteroids and their connections. Research in the field of studying near-solar asteroids is important for the development of the evolutionary theory of the Solar System. Currently, there is no theory of solar wind dynamics, and the study of the behavior of near-solar and near-Earth asteroids contributes to the construction of this theory. It is accepted that near-solar asteroids can be studied as near-Earth ones if they are in close proximity to the Sun, have small sizes and small perihelion distances. The work uses a simulation model of the dynamics of near-solar asteroids with small perihelion distances created by the authors. The replenishment of dust formations and rings existing in the inner part of the Solar System is considered. The distributions of orbital parameters are studied – the dependences of the eccentricity on the semi-major axis of the orbit and the orbital inclination on the semi-major axis of the orbit for NEAs are constructed. Temperature dependencies were constructed and analyzed – the dependence of isothermal and spherical temperature and subsolar temperature on the semi-major axis of the orbit for NEAs. Dependencies on color indices were obtained and analyzed. The results of this work are useful for understanding the physics of dynamic processes in both the Solar System and, as a consequence, contribute to the study of the evolution of exoplanet systems.

Abstract. We investigate the formation mechanism of a tropopause cirrus cloud layer observed during the Balloon measurement campaigns of the Asian Tropopause Aerosol Layer (BATAL) over Hyderabad (17.47° N, 78.58° E), India, on 23 August 2017. Simultaneous measurements from a backscatter sonde and an optical particle counter on board a balloon flight revealed the presence of a subvisible cirrus cloud layer (optical thickness ∼ 0.025) at the cold-point tropopause (temperature ∼ −86.4 °C, altitude ∼ 17.9 km). Ice crystals in this layer are smaller than 50 µm with a layer mean ice crystal number concentration of about 46.79 L−1. Simultaneous backscatter and extinction coefficient measurements allowed us to estimate the range-resolved extinction to backscatter coefficient ratio (lidar ratio) inside this layer with a layer mean value of about 32.18 ± 6.73 sr, which is in good agreement with earlier reported values at similar cirrus cloud temperatures. The formation mechanism responsible for this tropopause cirrus is investigated using a combination of three-dimensional back trajectories, satellite observations, and ERA5 reanalysis data. Satellite observations revealed that the overshooting convection associated with a category 3 typhoon, Hato, which hit Macau and Hong Kong on 23 August 2017, injected ice into the lower stratosphere. This caused a hydration patch that followed the Asian summer monsoon anticyclone to subsequently move towards Hyderabad. The presence of tropopause cirrus cloud layers in the cold temperature anomalies and updrafts along the back trajectories suggested the role of typhoon-induced waves in their formation. This case study highlights the role of typhoons in influencing the formation of tropopause cirrus clouds through stratospheric hydration and waves.

Abstract. Peatland management practices, such as drainage and restoration, have a strong effect on boreal peatland methane (CH4) fluxes. Furthermore, CH4 fluxes are strongly controlled by local environmental conditions, such as soil hydrology, temperature and vegetation, which are all experiencing considerable changes due to climate change. Both management practices and climate change are expected to influence peatland CH4 fluxes during this century, but the magnitude and net impact of these changes is still insufficiently understood. In this study, we simulated the impacts of two forest management practices, rotational forestry and continuous cover forestry, as well as peatland restoration, on hypothetical forestry-drained peatlands across Finland using the land surface model JSBACH (Jena Scheme for Biosphere–Atmosphere Coupling in Hamburg) coupled with the soil carbon model YASSO and a peatland methane model HIMMELI (Helsinki Model of Methane Buildup and Emission for Peatlands). We further simulated the impacts of climatic warming using two RCP (Representative Concentration Pathway) emission scenarios, RCP2.6 and RCP4.5. We investigated the responses of CH4 fluxes, soil water-table level (WTL), soil temperatures and soil carbon dynamics to changes in management practices and climate. Our results show that management practices have a strong impact on peatland WTLs and CH4 emissions that continues for several decades, with emissions increasing after restoration and clearcutting. Towards the end of the century, WTLs increase slightly, likely due to increasing precipitation. CH4 fluxes have opposing trends in restored and drained peatlands. In restored peatlands, CH4 emissions decrease towards the end of the century following decomposition of harvest residue in the top peat layers despite increasing WTLs, while in drained peatland forests sinks get weaker and occasional emissions become more common, likely due to rising WTLs and soil temperatures. The strength of these trends varies across the country, with CH4 emissions from restored peatlands decreasing more strongly in southern Finland, and forest soil CH4 sinks weakening most in northern Finland.

The actions necessary for the successful transfer of technology in the pharmaceutical sector—commonly referred to as technology transfer - constitute a systematic procedure. This process involves the transmission, implementation, and adaptation of information, research findings, new technologies, and developments. It serves as the foundation for production processes, control strategies, approaches to validation, and continuous improvement efforts. The specifics of knowledge transfer have been addressed, emphasizing the need for step-by-step documentation of all stages of the transfer process. The role of insufficient documentation of the knowledge required for transfer has been highlighted, as it can lead to ineffective transfer and serious issues during product release. The success of technology transfer is closely linked to the effective functioning of the pharmaceutical quality system at the site of stable production, aligned with the specified quality parameters established during development. The participation of the receiving party in the transfer process and the importance of accounting for and maintaining documentation have been emphasized. Additionally, the significance of the receiving party’s role in evaluating the relevant documents from the transferring party, considering the specific differences between the sites of both parties, has been noted. The importance of analytical methods in their transfer has also been recognized.

In recent years, functional foods have gained increasing importance in the food industry due to their positive impact on health. In response to the growing demand, experts in food technology and healthcare have focused their efforts on developing effective methods for controlling their use to strengthen health, improve nutrition, and enhance overall well-being. The study investigated the probiotic properties of 27 strains of lactobacilli, from which 5 strains with high acid production capacity and antagonistic activity were selected, as well as 3 strains with antibiotic resistance and biocompatibility. Based on the strains L. acidophilus AA1, L. plantarum 8PA-3, and L. rhamnosus GG, a functional chocolate was created, enriched with symbiotics at a concentration of 109 CFU/ml. The strains with pronounced probiotic properties, combined with the prebiotic inulin in a 1:10 ratio, were microencapsulated in a natural polysaccharide. A technological scheme for producing functional dark chocolate with pro- and prebiotic microcapsules was developed using inulin from Jerusalem artichoke in a 3:100 ratio as a sugar substitute.
В последние годы функциональные продукты приобретают всё большее значение в пищевой промышленности, благодаря их положительному влиянию на здоровье. В ответ на растущий спрос специалисты в области пищевых технологий и здравоохранения сосредоточили свои усилия на разработке эффективных методов контроля их применения для укрепления здоровья, улучшения питания и повышения общего благополучия. В ходе исследования были изучены пробиотические свойства 27 штаммов лактобактерий, среди которых было выбрано 5 штаммов с высокой способностью к образованию кислоты и антагонистической активностью, а также 3 штамма, обладающие устойчивостью к антибиотикам и биосовместимостью. На основе штаммов L. acidophilus AA1, L. plantarum 8РА-3 и L. rhamnosus GG был создан функциональный шоколад, обогащённый симбиотиками в концентрации 109 КОЕ/мл. Штаммы с выраженными пробиотическими свойствами совместно с пребиотиком инулином в соотношении 1:10 были подвергнуты микрокапсулированию в натуральном полисахариде. Технологическая схема производства функционального тёмного шоколада с про- и пребиотическими микрокапсулами была разработана с использованием инулина из топинамбура в соотношении 3:100 как заменителя сахара.

The article provides an analysis of data on the impact of drought on vegetation cover. Severe drought leads to the accumulation of salts and ions in the upper layers of the soil, which results in osmotic stress and ionic toxicity of plants. With an increase in the degree of stress from drought, the turgor pressure of plant cells decreases, as a result of which the state of the cell walls changes. The phytocenotic composition of the sands of the Small Moyinkum along the Almaty-Konaev highway has been studied. Vegetation is represented by only 10 plants with a single tree species Ulmus pumila of artificial origin. Botanical studies on the studied breed showed the following: the average dominant and maximum age of the trees was 20-30 years. One of the ways plants adapt to arid cultivation conditions is the presence of endophytic microorganisms living inside the tissues, which largely determine the overall metabolism of the plant. To isolate endophytic microorganisms, xerophytic, mesoxerophytic and xerophytic plants most adapted to arid growing conditions were selected.
В статье приведен анализ данных по влиянию засухи на растительный покров. Сильная засуха приводит к накоплению солей и ионов в верхних слоях почвы, следствием которого является осмотический стресс и ионная токсичность растений. С увеличением степени стресса от засухи тургорное давление растительных клеток снижается, в результате чего изменяется состояние клеточных стенок. Изучен фитоценотический состав песков Малого Мойынкума вдоль автодороги Алматы-Конаев. Растительность представлена всего 10 растениями с единственной древесной породой Ulmus pumila искусственного происхождения. Ботаническое изучение исследуемой породы показало следующее: средний доминантный и максимальный возраст деревьев составил 20-30 лет. Одним из способов адаптации растений к засушливым условиям выращивания является наличие эндофитных микроорганизмов, живущих внутри тканей, которые во многом определяют общий метаболизм растения. Для выделения эндофитных микроорганизмов были отобраны ксерофитные, мезофитные и одноклеточные растения, наиболее приспособленные к засушливым условиям произрастания.

The medicinal properties of fermented milk products largely depend on the quantity and quality of antibiotic substances formed in the products during their preparation, and are determined to a large extent by the species composition and activity of the starter cultures used. Starter cultures must have pronounced antagonistic activity against pathogenic and opportunistic bacteria. In this article, the objects of study were new strains of lactic acid bacteria isolated from natural sources. The main candidates for inclusion in the starter consortium were selected, 7 strains of lactobacilli: 021pK, 022pK, 031pK, 068pK, 071pK, 074kA, 075kA. They have a high rate of antagonistic activity and inhibit the growth of opportunistic and pathogenic bacteria.
Лечебные свойства кисломолочных продуктов во многом зависят от количества и качества антибиотических веществ, образующихся в продуктах в процессе их приготовления, и определяются в значительной степени видовым составом и активностью используемых заквасок. Заквасочные культуры должны обладать выраженной антагонистической активностью по отношению к патогенным и условно-патогенным бактериям. В данной статье объектами исследования послужили новые штаммы молочнокислых бактерий, выделенных из природных источников. Отобраны основные кандидаты для включения в консорциум заквасок, 7 штаммов лактобацилл: 021пК, 022пК, 031пК, 068пК, 071пК, 074кА, 075кА. Они имеют высокий показатель антагонистической активности и ингибируют рост условно-патогенных и патогенных бактерий.
