Кл.слова (ненормированные):
диэлектрическая модель -- влажность -- температура -- органическая почва -- минеральная почва -- мерзлая почва -- талая почва -- dielectric model -- moisture -- temperature -- organic soil -- mineral soil -- frozen soil -- thawed soil
Аннотация: На основе рефракционной диэлектрической модели создана одночастотная диэлектрическая модель талых и мерзлых лесных почв корневой зоны, учитывающая влияние как минеральной, так и органической компоненты почвенной смеси. Модель разработана для частоты 435 МГц на основе диэлектрических измерений пяти почв, в которых содержание органического вещества варьировалось от 11,1 до 54,4 % и глины от 21,1 до 40,9 %. Диэлектрические измерения были проведены в диапазоне массовой влажности от сухого состояния до наименьшей влагоемкости и диапазоне температур от – 30 до 25 ℃. В исследуемом диапазоне температур коэффициент детерминации между рассчитанными с использованием предложенной модели и измеренными значениями действительной (ε') и мнимой (ε") частями комплексной диэлектрической проницаемости составляет 0,988 – 0,997 для ε' и 0,957 – 0,971 для ε". Нормированное среднеквадратическое отклонение при этом составило 6 – 5,6 % для ε' и 20,2 – 21,2 % для ε". Разработанная диэлектрическая модель может быть применена в алгоритмах дистанционного зондирования при восстановлении значения влажности лесных почв корневой зоны из данных радарного и радиометрического зондирования.
The single-frequency dielectric model of thawed and frozen forest soils in the root zone based on the refractive dielectric model was created, taking into account the influence of both the mineral and organic components of the soil mixture. The dielectric model was created on at 435 MHz the basis of the laboratory dielectric measurements of five soils with organic matter content in the range from 11.1 to 54.4 % and clay content from 21.1 to 40.9 %. Dielectric measurements were carried out in the range of the gravimetric moisture from the dry state to the lowest moisture capacity and in the temperature range from –30 to 25 ℃. The coefficient of determination between the predicted and measured values for real and imaginary parts of the complex permittivity are 0.988 - 0.997 and 0.957 - 0.971, respectively. The normalized standard deviations in this case are 6 - 5.6 % and 20.2 - 21.2 % for real and imaginary parts of the complex permittivity, respectively. The developed dielectric model can be used in remote sensing algorithms of soil moisture retrieval of forest soils in the root zone from the data radar and radiometric.

Photo-biological effectiveness of PAR for radish plant communities irradiated using an LED source with an adjustable spectrum / A. A. Tikhomirov, M. S. Molokeev, V. V. Velichko // Light Eng. - 2024. - Vol. 32, Is. 2. - P. 70–77, DOI 10.33383/2023-063. - Cited References: 15. - The study was carried out with financial support within the framework of State Assignment 121101300066-7 of the Ministry of Education and Science and the Strategic Academic Leadership Program "Priority-2030" for the Siberian Federal University . - ISSN 0236-2945. - ISSN 2541-9935
Кл.слова (ненормированные):
spectral composition of radiation -- spectral effectiveness of radiation -- variable radiation spectrum -- fluorescent LEDs -- radish productivity
Аннотация: The aim of the current study was to find the most effective spectral modes of irradiation of short-season plants (for example, radish) using a fluorescent LED irradiator with a variable spectrum. The research methodology was based on the species-specific response of plants to the spectral composition of light. Photo-biological experiments were carried out to find effective spectral composition of PAR for cultivating radish communities under stable and variable irradiation modes of electrical lighting. It was shown that under stable irradiation modes, the highest productivity of economically useful radish biomass had been achieved at spectral composition with a maximum of 60 % radiation in the (600–700) nm region in a variable spectral irradiation mode. The variable spectral irradiation mode turned out to be the most effective when the spectral composition with the dominance of red rays was changed to the spectral composition with the dominance of blue rays. There were no significant differences between the best production parameters for stable and variable modes of irradiation of radish plants, which indicates the expediency of choosing the stable spectral mode of irradiation of radish plants as a short-season crop under electrical illumination. The results obtained can be used to select spectral irradiation modes for short-season plants grown under electrical lighting in northern regions and in isolated rooms in various climatic zones using "City-farm" technologies.

Кл.слова (ненормированные):
Concrete optimization -- Random forest -- Decision tree -- Machine learning -- Сement concrete roads
Аннотация: Current manuscript presents a study on the use of 48 experimental data points containing parameters of concrete production technological process and its properties, such as strength, density, and bending strength. It was revealed that temporal characteristics, specifically - compressive strength at the age of 3, 7, 28 days, R3, R7, and R28, are significantly correlated with each other, indicating that only one characteristic, such as R28 or Rfl 28, is sufficient for prediction. The absence of multiple correlations between parameters and properties suggests that linear regression analysis may not be accurate. Therefore, the use of Machine Learning is optimal; specifically Random Forest method is preferable due to ease of use and minimum hyperparameters for tuning. Low prediction errors (?1–11%) for 30% of the test data, as determined by the cross-validation method, confirm a relationship between the experimental parameters and the concrete properties. The most important parameters for achieving high values of compressive and bending strengths, R28 and Rfl 28, were identified, namely: air-entraining additives, granite crushed stone consisting of a mixture of fractions 5–20 mm, crushed stone derived from gravel of high strength grains of large fractions 10–20 mm. To obtain explanatory model, another Machine Learning method, that was used, called Decision Tree. The model showed that a high amount of crushed stone 10–20 mm from gravel, more than 212 (kg per 1 m3 of concrete mix), leads to a higher number of strong grains with smooth, rounded surface, thereby, reducing the bending strength of concrete. However, a large concentration of crushed stone mix fractions of 5–20 mm from granite, more than 537 (kg per 1 m3 of concrete mix), leads to the maximum roughness, which makes a significant contribution to the increased strength of concrete due to the adhesion of the matrix and aggregates to each other.

Кл.слова (ненормированные):
biosynthesis -- different precursors -- sulfur-containing PHAs -- chemical composition -- 3MP monomers contents -- properties
Аннотация: The study addresses the growth of the wild-type strain Cupriavidus necator B-10646 and the synthesis of sulfur-containing polyhydroxyalkanoates (PHA) by this strain on media containing fructose and three different precursors (3-mercaptopropionic acid, 3′,3′-dithiodipropionic acid and 3′,3′-thiodipropionic acid). By varying the concentration and number of doses of the precursors added into the bacterial culture, it was possible to find conditions that ensure the formation of 3-mercaptopropionate (3MP) monomers from the precursors and their incorporation into the C-chain of poly(3-hydroxybutyrate). A series of P(3HB-co-3MP) copolymer samples with different content of 3MP monomers (from 2.04 to 39.0 mol.%) were synthesized and the physicochemical properties were studied. The effect of 3MP monomers is manifested in a certain decrease in the molecular weight of the samples and an increase in polydispersity. Temperature changes are manifested in the appearance of two peaks in the melting region with different intervals regardless of the 3MP content. The studied P(3HB-co-3MP) samples, regardless of the content of 3MP monomers, are characterized by equalization of the ratio of the amorphous and crystalline phases and have a close degree of crystallinity with a minimum of 42%, = and a maximum of 54%.

Photocatalytic water splitting -- Novel materials -- Transition metal dichalcogenides -- H2 generation
Аннотация: The successful fabrication of H-phase Janus transition metal dichalcogenides (TMDs) has received considerable interest due to its great potential in photocatalytic applications. Here, new A′-XMoY (X/Y = O, S, Se, Te) Janus-type structures belonging to the family of TMDs were theoretically investigated for the first time in terms of photocatalytic water splitting via DFT calculations. For all compounds, the Raman spectra were calculated. The SMoO, SeMoO, SMoSe, SMoTe and SeMoTe compounds are dynamically stable and are semiconductors. Among all considered structures SMoTe is the most promising candidate for solar hydrogen production because valence and conduction bands perfectly engulf the redox potentials of water at both neutral and acidic media, opposite to SMoSe, SMoO, SeMoO suitable only in the acidic media, and SeMoTe – in the neutral media. Moreover, A′-SMoTe demonstrates the outstanding values of the solar-to-hydrogen (STH) conversion efficiencies of 54.0 and 67.1 for neutral and acidic media.
