Published: May 2024

The work objective is to evaluate the ecotoxicity of silver nanoparticles (AgNPs) according to the state of the biota of Haplic Chernozems Calcic. Contamination of Haplic Chernozems Calcic with 10 nm AgNPs in concentrations of 0.1, 0.5, 1, 5, 10, 50, and 100 mg/kg was simulated in laboratory conditions. In this study, biodiagnostical methods were used to assess the ecotoxic effect of AgNPs on soil biota: the activity of catalase, dehydrogenases, invertase, phosphatase, urease, the total number of bacteria, the Azotobacter sp. abundance, germination, and length of radish roots. The response of soil biota to exposure to AgNPs was assessed by the difference between the values in contaminated and uncontaminated soil. It was found that the more silver nanoparticles were introduced into the soil, the stronger the ecotoxic effect on the biota. The highest sensitivity degree to contamination of Haplic Chernozems Calcic with AgNPs was recorded for the total number of bacteria. The critical value of the AgNPs content in Haplic Chernozems Calcic, which is 0.4 mg/kg has been developed.

Authors: Denisova S.G. , Reut A.A.
Published: May 2024

The purpose of the research is to study the influence of the substrate and plant growth stimulants on the rooting of cuttings of some varieties of Chrysanthemum coreanum (H. Lev. & Vaniot) Nakai garden group ‘Multiflora’. Four varieties of Chrysanthemum introduced into the South-Ural Botanical Garden-Institute of Ufa Federal Research Center of Russian Academy of Sciences (‘Sunbeam Bronze Bicolor’, ‘Meridian Red’, ‘Ditto Dark Pink’ and ‘Daybreak Apple Blossom’) were used as research objects. We examined the influence of two types of substrates (sand and vermiculite) and four growth stimulants on the rooting of chrysanthemums (Zircon, Lignohumate brand AM potassium, Beres Super seaweed extract, Beres AminoComplex). It was revealed that the treatment of chrysanthemum cuttings with plant growth regulators contributed to an increase in the number (by 7−117%) and length of roots (by 3−118%) in the majority of the studied objects. It was noted that positive results from the use of preparations were obtained when chrysanthemum cuttings were placed in vermiculite, in contrast to options with sand as a substrate. It has been shown that the greatest effect is noticeable when cuttings are soaked in Beres AminoComplex and Beres Super solutions compared to the control option. Varietal differences in chrysanthemums to the effects of root formation stimulants during vegetative propagation have been revealed. Thus, in the varieties ‘Ditto Dark Pink’ and ‘Daybreak Apple Blossom’, an improvement in the biometric parameters of cuttings was observed when rooted in vermiculite after exposure to plant growth regulators. It was noted that when chrysanthemum cuttings are soaked for three hours, in contrast to their wetting, the number of roots increases by 38−88% in all variants of the experiment.

Published: May 2024

Over the past decades of forestry development in Russia, the main trends have been identified, according to which P. sylvestris planting material can be effectively grown in a container method with a closed root system, considering the forest-seed area. The purpose of the study was to study the annual dynamics of ammonium and nitrate nitrogen in a soil with P. sylvestris with a closed root system using encapsulated urea with hydroquinone and mulch. The objectives of the study were based on the study of the effect of mineral fertilizers on the annual dynamics of ammonium and nitrate nitrogen and their effect on the growth of seedlings. The object of the study was the dynamics of the content of these nitrogen compounds in the soil. The study was carried out by methods of agrochemical, biometric and statistical analysis. Thus, the use of extended-form carbamide makes it possible to cover the need of plants for nitrogen nutrition throughout the growing season, having a significant impact on their growth in stem height. The use of encapsulated carbamide with hydroquinone, 0.5 cm pine mulch, potassium monophosphate and phosphorous flour allows the production of the best P. sylvestris seedlings with a maximum height of 188.82±15.41 mm per year due to constant saturation of the soil with available nitrogen, on which a change in the growth rate of seedlings is almost directly dependent (R = 0.99821-0.99988; Multiple R = 0.99643-0.99977; Adjusted R = 0.98928-0.99930; p < 0.01525-0.05978). At the same time, ammonium nitrogen has the greatest effect on it (p < 0.01633-0.05436).

Published: May 2024

The article shows the yield of spring soft wheat in different technologies in the absence of autumn tillage. Technologies differ in the place of wheat in crop rotation and the use of fertilizers. Soil tillage in experiment No. 1 in a four-field grain-fallow crop rotation and on permanent wheat is zero. In experiment No. 2, stubble was left in autumn on long (24 yields) repeated wheat crops, where the soil loosens only when sown with a seeder SKP-2,1 with a cultivator-type coulter. With zero tillage with the removal of crops from fallow, the yield from 1,7 t/ha in the 1st field in the following crops decreased by 1,31-1,44 times, against the background of fertilizer in 1,08-1,12. Permanent sowing of wheat on stubble, compared with the yield of fallow, reduced grain harvest on backgrounds N0 and N40 by 1,60 and 1,42 times. Yield of 2,5 t/ha were obtained in the 1st field after fallow only in a favorable year, as in the following field. Due to fertilizer N40 in such a year, grain harvest increased in three crops of the crop rotation to 2,7-3,0-3,3 t/ha in up to 2,9 t/ha of permanent wheat. The formation of a high yield of wheat by fallow was facilitated by the preservation of the number of productive stems at an average level of 291 pieces per 1 m2, whereas on other backgrounds there were 274-265 and 243 with permanent cultivation. The number of grains in the ear was of great importance, which reached 18,1-20,2 pieces in fallow with 14-15 in other technologies.
Justification of the effective distribution of energy emitted by a film electric heater on stacked lumber
Authors: Levinskiy V.N.
Published: May 2024

The research was carried out at the expense of the grant of the Russian Science Foundation No. 23-76-01090, https://rscf.ru/project/23-76-01090/. The article considers the issue of placing boards in a drying plant using infrared film electric heaters. Two options for placing one cubic meter of boards with a thickness of 25 mm and 50 mm are proposed for consideration. The boards are placed between shields with film electric heaters and are separated from each other by transverse gaskets, it is obvious that more gaskets are needed to accommodate boards with a thickness of 25, which means that the distance between the boards will be greater. Hence the hypothesis: an increase in the distance between the shields will lead to an increase in drying time and electrical energy costs. For a theoretical solution, the following is proposed – to present the piled stack in the form of a prism and, considering the known dimensional parameters of the skipped shield, according to a well-known formula, it is possible to obtain a dependence describing changes in the irradiation coefficient on the distance in the radiator-receiver system. The considered irradiance coefficient shows how much of the total radiation from the area of the “receiver” falls on the surface of the “receiver”. As a result, an exponential dependence is obtained, according to which it can be determined that the irradiation coefficient for the placement of boards with a thickness of 25 mm is 8% less than for boards with a thickness of 50 mm, which ultimately will affect the duration of the drying process and the cost of electrical energy. Options are proposed to increase the drying efficiency by increasing the irradiation coefficient by reducing the distance between the panels with film electric heaters. In conclusion, in view of the result described in this article, the main directions for further research on improving the “radiator-receiver” system in relation to drying plants based on film electric heaters are given.

The most significant characteristics of the soil are water-physical, biological and other properties, by influencing which it is possible to increase the productivity of agricultural crops. Analyzing various soil characteristics is a very labor-intensive and expensive process. The authors reviewed research on the use of artificial intelligence systems in the field of soil analysis. The purpose of the study is to analyze research on the use of artificial intelligence systems in the field of soil analysis. The article presents an analysis of artificial intelligence systems based on artificial neural networks (ANN), adaptive neuro-fuzzy inference system (ANFIS), support vector machine (SVM), multiple regression (MR) methods, particle swarm algorithm (PSO) and also their ensembles (various combinations). The use of these systems (their models) makes it possible to predict various types of soil erosion, predict soil temperature and moisture depending on various conditions, and also predict such complex indicators as the cation exchange capacity of the soil. The scope of application of artificial intelligence systems is to increase the awareness of managers and specialists of agricultural organizations and industry management bodies about various soil characteristics. This, in turn, allows you to make optimal decisions on various agricultural activities. Artificial intelligence systems can process significant amounts of data with high accuracy and speed compared to humans, which makes it possible to more effectively analyze many factors affecting the condition of the soil. The use of artificial intelligence systems can significantly reduce the cost of analyzing various soil characteristics and is a necessary condition for the use of precision farming systems.

Published: May 2024

Radiation-induced processes in germ reproductive cells, as well as the effect of low doses of radiation on the reproductive potential of farm animals remain poorly studied. Assessing the radiation effects of low doses on gametes and early embryos will reveal biological features that are important for assisted reproductive technologies in animal husbandry. In addition, the study of the processes of maturation and fertilization of irradiated gametes and the subsequent development of early preimplantation embryos will make it possible to update measures to protect the health and reproductive potential of farm animals in conditions of technogenic radiation risks. In this study, we focused on analyzing the effects of irradiation on the ovaries of cattle and examining the consequences of this exposure on embryo development under in vitro fertilization conditions. We used X-ray radiation of different dose rates with an absorbed dose of 100 mGy. The research results showed a decrease in the frequency of blastocyst formation in all experimental groups of embryos obtained from oocytes of irradiated ovaries. The data obtained can serve as a scientific basis for the development of measures to preserve the reproductive potential of farm animals under technogenic radiation risks, as well as for further search of ways to improve assisted reproductive technologies in animal husbandry.

Authors: Saveliev Leonid A.
Published: May 2024

In 2024, due to sanctions restrictions, the availability of medical raw materials may be seriously limited, which acutely raises the question of the availability of its own, Russian base of medicinal raw materials. The concept of pharmaceutical safety of the country involves expanding the range of cultivated medicinal plants, primarily in the northern regions, where special soil and climatic conditions (long daylight hours, low temperatures of the growing season, soil conditions) allow plants to accumulate a greater amount of biologically active substances compared to plants cultivated in the southern regions. One of the most valuable, but sparsely distributed species of medicinal plants is the common autumn crocus (Colchicum autumnale), which contains a sparsely distributed alacloid – colchicine. Colchicine is a valuable alkaloid used in medicine and in plant breeding. Previously, it was found that the common autumn crocus containing the alkaloid colchicine tolerates winter in South Karelia and can be used as a local source of colchicine. In this regard, the purpose of our research was to study the features of the introduction of the common autumn crocus on sod-podzolic mineral soils of South Karelia.

Published: May 2024

A soil survey was carried out under the collection plantings of Prunus cerasifera Ehrh., growing on the experimental site of the Nikitsky Botanical Garden. During the research, the morphological structure, granulometric composition, pH, content of carbonates, humus, exchangeable potassium, oxalate-soluble (amorphous) iron were studied using generally accepted methods of soil analysis. The content of mobile forms of micronutrients and heavy metals (Zn, Cu, Mn, Pb, Cd) was determined in ammonium acetate extract at pH=4.8. It was revealed that the soils of the experimental site are characterized by favorable physical, chemical properties and agrochemical parameters for cherry plum plants, including uniform distribution of humus along the profile, slightly alkaline reaction, low content of carbonates, high content of available potassium. Among the mobile forms of trace elements and heavy metals, exceeding of the maximum permissible concentration was found only for copper, the source of which is copper-containing fungicides. The slightly alkaline reaction of the soil contributes to a decrease in the mobility of micronutrients and heavy metals, therefore, even with their excessive content in the soil, there was no excess of maximum permissible concentration in cherry plum fruits.

Authors: Prakh A.V. , Yakuba Yu.F. , Redka V.M. , Reznichenko K.V. , Prakh A.A.
Published: May 2024

The quality of wine depends not only on the balance of volatile and non-volatile macro-components, but also on the content of micro-components contained in ng, such as methoxypyrazines. They form shades of green vegetables – peas, asparagus, which are undesirable in excess for grape wines. Due to extremely low concentrations and serious interference from the complex wine matrix, their direct quantitative analysis is difficult. The general opinion of the researchers indicates that the direct determination of methoxypyrazines by available chromatography methods is practically impossible. Therefore, as a sample preparation, various types of extraction concentration are mainly offered, providing for subsequent concentrate purification. The possibilities of different variants of the QuEChERS technology are evaluated. The information analysis suggests that QuEChERS preparation will be the most accessible and effective, which can then be easily combined with analysis by gas-liquid chromatography methods. Due to the volatility of methoxypyrazines, capillary GLC with a highly sensitive detector is proposed as the main method of analysis. Some advantage is given to multidimensional analysis: the use of a mass spectrometer in combination with a flame ionization detector shows higher reliability of the results. The use of a fairly simple but reliable flame ionization detector, which is able to ensure the reliability of measurements, is evaluated. In general, the approaches proposed by the researchers make it possible to ensure the necessary accuracy and quality of the quantitative determination of methoxypyrazines in wine samples.

Published: May 2024

Non-uniform series resistance design of VCSEL arrays is studied to improve thermally induced current bifurcation based on an electro-opto-thermal model of VCSEL arrays. Taking an 850nm VCSEL array with 4×4 cells for example, the impact of series resistance on current bifurcation is investigated. Increasmg series resistance is helpful to enhance the critical current values of current bifurcation point (Irc) and hence delay the current bifurcation phenomenon. For VCSEL array with non-uniform series resistance, Irc is increased by 28.6% and the total output optical power is enhanced by 14.3% when compared with that of VCSEL array with uniform series resistance. Therefore, non-uniform series resistance design is a better method for delaying the current bifurcation phenomenon and enhancuig the output optical power of VCSEL arrays.

Since the reform and opening up, China has introduced modern commercial management ideas for cultural tourism from abroad, and cultural tourism resources have been fully developed and utilized, greatly enriching the material and cultural life of the people. The author of this paper is passionate in touring and Chinese history and culture. After visiting many tourist attractions in China, it was found that there are some "flaws" in the development and utilization of the domestic cultural and tourism industry. Firstly, the development of cultural and tourism resources is overly commercialized, emphasizing the hardware construction of scenic spots, and neglecting the deep exploration of historical and cultural connotations, resulting in a serious phenomenon of homogenization of scenic spots throughout the country. Only a glimpse can reveal the whole picture. Secondly, there is a serious decoupling between hardware construction and software construction, and there is still significant distance for improvement in the service level of scenic spots. The comprehensive quality of practitioners is not well enough, and they are older in age; Finally, there is a serious talent gap in cultural and tourism related fields, and the development of cultural and tourism professional talents does not match the actual needs. This paper proposes a solution to the problem of decoupling cultural and tourism talent cultivation from actual needs: optimizing the curriculum system, strengthening practical teaching, and promoting the integration of industry, academia, and research.

Authors: Xiao He , Suwanarak Kasma
Published: May 2024

The overarching objective of this study was to explore online learning effect of English writing combining teachers’ teaching engagement with perceptive interaction behaviour of students. The Utrecht Work Engagement Scale (UWES) of online teaching and the questionnaire of perceptive interaction behaviours from students were adopted to find the appropriate participants in this study, and finally four teachers with different levels of work engagement (high vs. low) were selected and 100 undergraduates in university with Perceptive Oral Interaction (POI) and Perceptive Written Interaction (PWI) were verified, One-way ANOVA were used to check the homogeneity of variances (p< .05). Through the writing test scores, the two-way ANOVA was conducted to find whether the teachers’ engagement (high vs. low) affects students’ English writing learning, whether the types of perceptive interaction behaviours (POI vs. PWI) affect their English writing learning gains, and whether there is an interaction between teachers’ engagement and types of perceptive interaction behaviours on their English writing learning. The results shows that there is a significant interaction between teacher’s online work engagement and students’ online behavioural perceptive interaction, and students with POI behaviour under the guidance of high work engagement from teachers yield higher learning gains than the other groups. However, the results also shows that students with POI got lower effect than students with PWI when they all met the teachers with low online work engagement, which need to be further studied in the future.
Theoretical concerns and compensation strategies on student-centered theory
Authors: Chi Mingyang , Ye Ruiling , Fu Shuang
Published: May 2024

Student-centered theory is the fundamental concept of current education reform, as well as the fundamental requirement of classroom instruction. Student-centered education has gone through four stages: enlightenment, development, formal proposal, and in-depth investigation. Student-centered education reform is a long-term investigation that emphasizes that by emphasizing students’ dominant position, teachers return the classroom to students and realize the leap of students’ freedom. However, the complexity of the real education field creates a new teaching dilemma due to the centrality of its theory, resulting in an excessive burden on students’ academic burden and the exile of educators’ responsibility. The way to fix the student center theory is to consider both the survival and development of students, ensure the return and responsibility of educators, and implement a student-centered reform that takes care of reality, according to the composition of the educational field and the core of the student center.
