Published: June 2024

Rapid changes and the increasing complexity of modern education system brought forth numerous challenging situations for teachers and scholars of different fields. Amongst, the most challenging task is the innovation and application of unique and different teaching methodologies, which further balances the curriculum and increases the learning capacity of students. Many teaching methods already exist in the field of education such as Lecture Method, Discussion Method, Socratic Questioning Method etc. These methods are used both collectively and separately. The established efficiency of these methods is evident by their exponential relevance in different fields. However, to transfigure teaching into a riveting experience for students, there is need of more conscious efforts to devise new teaching skills or to draw inspiration from the core theoretical work of renowned scholars of different fields and apply those ideas, directly or with some modifications in the classroom teaching. Therefore, in the present article, an effort has been made to understand the application and relevance of Max Weber’s Verstehen approach as a teaching method in classroom settings.

Authors: Albuja Urvina M Gabriela , Pérez Pérez Paulina del Rocío
Published: June 2024

Se observa que en los últimos años un creciente número de adultos mayores, con una mayor expectativa de vida, han normalizado como parte del proceso de deterioro propio de la edad cambios como la pérdida de memoria, lenguaje entre otros, pese a las dificultades que esto representa en su vida diaria y estos síntomas pueden derivar en trastornos neurológicos como, Alzheimer, entre otros. La presente investigación tiene como objetivo comparar el estado cognitivo de adultos mayores en tres ámbitos: aquellos que están institucionalizados, aquellos que acuden a programas de estimulación cognitiva y aquellos que viven por su propia cuenta. Este es un estudio cuantitativo no experimental con una muestra no probabilística donde se empleó el Montreal Cognitive Assessment en una población de 371 adultos mayores. Se encontró deterioro cognitivo en el 99% de pacientes institucionalizados en geriátrico, el 75% en quienes asisten a programas de estimulación cognitiva y el 83% de personas que no asisten a programas. No hay diferencia significativa en cuanto el nivel de estudios cursados, de igual manera con respecto al sexo de los participantes. Las áreas más afectadas son: dominio visoespacial, lenguaje y recuerdo diferido. Se puede concluir que el deterioro cognitivo no es un trastorno que se presente en un grupo especifico de personas, puede afectar a individuos tanto hombres como mujeres, independiente de su nivel académico. De igual forma, tanto aquellos que están institucionalizados, o en programas de estimulación presentan deterioro cognitivo, el porcentaje de pacientes que no tienen un desempeño normal es muy reducido en los tres ámbitos.

Published: June 2024

The present study aims to investigate how organizational sensemaking contributes towards sustainability performance (i.e., environmental performance and social performance) by proposing green dynamic capabilities as underlying mechanisms. It uses time-lagged design and the data were collected in two waves, from 232 agribusiness organizations in Romania using an online survey. PLS-SEM was employed in WarpPLS 8.0 software to analyze the data and test the hypothesized relationships. Results showed that organizational sensemaking positively influences both dimensions of sustainability performance. Moreover, the results also supported the mediating role of green dynamic capabilities. Findings imply that organizations that are proficient in sensing and interpreting external events, cues, and changes can successfully strengthen internal business processes (by developing green dynamic capabilities) to address environmental concerns, which in turn helps these organizations to achieve enhanced sustainability performance. The novelty of this study is the development of a dynamic-capabilities-based integrated framework for sustainability performance.

Published: June 2024

It is necessary to reduce engine fuel consumption for loaders to overcome the energy crisis faced by today's society. To this end, a hybrid loader arm energy recovery and reuse system is proposed, adding an electrical energy recovery and reuse system to the conventional loader arm system and effectively reducing the loader engine fuel consumption and emissions. The principle of the system is analyzed, the mathematical model of the system components is analyzed, and AMESim models the system. The simulation results show that the system does not affect the regular motion characteristics of the boom arm cylinders. The energy recovery efficiency of the system reaches 58.9 %, and the energy reuse efficiency reaches 86.9 % after four operation cycles. The system can recover energy in hybrid, pure engine, and motor modes. The system's engine provides 24.8 % less energy, engine fuel consumption is reduced by 24.9 %, and pollutant emissions CO, HC, and NOx are reduced by 19.2 %, 25.9 %, and 23.6 %, respectively. The system provides a reference for the research of energy-saving technology for loaders.

Authors: MENACER Brahim , SOUALMIA Abdelkader , NARAYAN Sunny , AL-LEHAIBI Moaz
Published: June 2024

In Compression ignition engines combustion occurs at higher temperatures that leads to a rapid rise in combustion pressure and amount of heat released. This may lead to lesser emissions during engine cycle. Moreover, occurrence of combustion takes place for a very small crank angles duration resulting in better thermal efficiency. On the other hand, the oil used for lubrication in IC engines is responsible for a significant amount of pollution and particles emitted into the environment. In order to comply with increasingly strict pollution standards, manufacturers make considerable efforts to minimize the impact of oil consumption on engine emissions. The purpose of this study is to develop a one dimensional numerical simulation method using GT-Suite software to assess how the engine speed and load affect the oil film thickness, frictional force, and power losses during the operating engine cycle. The results obtained in this simulation were validated using experimental data, and there is good agreement between the numerical and experimental results. It was found in this paper that the maximum friction power losses were found to be 1.6 kW at middle of strokes and the minimum Oil film thickness was obtained in range of 9-38 μm.

INFLUENCE OF BLAST FURNACE SLUDGE AND CONVERTER SLAG ON VETCH PLANTS DEPENDING ON THE ACIDITY OF THE ENVIRONMENT
Authors: Baranchikov P. , Chebotaryova S. , Zakharova Olga
Published: June 2024

The use of waste as raw material to obtain commercially promising products allows us to solve a whole range of environmental, economic and social problems, especially during a crisis. The main share of unused waste consists of metallurgical waste, which can be a source of microelements for plants. Slag waste, due to its component composition, can also act as a soil degrader. The goal of the work is to create a technology for using dried blast furnace sludge alone or in combination with converter slag in agricultural production as a microelement fertilizer to increase the productivity of agricultural plants; reducing the volume of metallurgical waste disposed of in landfills.
Using electron microscopy, it was found that blast furnace sludge granules reach a size of 15 microns, while the size of converter slag particles ranges from 20 to 500 microns. Analysis of the elemental composition of the slag sample showed that the waste contains Ca, Fe, Mg, Si, Al, Mn. The composition of blast furnace slurry includes Fe, Zn, Al, Ca, Si, Na. Using X-ray diffraction analysis, it was established that the predominant compound in the converter slag is calcium oxide (53%). The composition of blast furnace sludge mainly includes iron oxide.
The results of the study showed high tolerance of vetch at a sludge concentration of 0.1 g/kg in acidified soil conditions, the increase in stem length increased by 17%, and its wet biomass increased by 30%. The increase in root length was 48%. The greatest increase in the dry mass of the stem was observed when sludge was added at concentrations of 0.01 g/kg (+71%) and 1 g/kg (+86%) in acidified soil against the background of the addition of slag. The accumulation of zinc extracted from blast furnace sludge in plant tissues of vetch has also been established.
Thus, the studied waste from metallurgical production can be used as a mineral fertilizer, since it contains microelements necessary for the mineral nutrition of plants.
STUPINSKOYE FIELD NATURE MONUMENT: CURRENT PRESERVATION OF 60-YEAR-OLD SCOTS PINE TREES IN DIFFERENT ECOTYPES OF GEOGRAPHICAL FOREST CROPS
Authors: Mihaylova Mariya , Chernyshov Mikhail
Published: June 2024

Specially protected natural areas play an important role in the conservation of biological and species diversity. The range of geographical forest crops of scots pine "Stupinskoye field" is a regional natural monument, which contains more than 425 of its ecotypes from different regions of the USSR. The biological age of the trees has reached 60 years. In this regard, the issues of their preservation at the stage of transition of seed progeny from middle-aged to mature ones are of great practical importance.
As a result of the conducted comprehensive studies, it was found that by the age of 60, no clear pattern reflecting the current preservation of trees in 32 sample areas (PP) is traced. However, the current preservation of trees in the seed progeny of steppe ecotypes is less (4.78%) than in the progeny of forest-steppe ecotypes (7.05%). These differences are significant with a probability of 0.95. The coefficient of reliability of differences t=3.69 > 1.98.
The amplitude of the boundaries of changes in the values of the current preservation of trees in forest-steppe ecotypes is wider (6.7%) than in steppe ecotypes (5.0%).

Published: June 2024

One of the most perspective regions in terms of introduction for the conditions of the central part of Russia is North America. It is of particular interest because the geographical location of North America and the central part of Russia have similar climate and soils. Therefore, the probability of a good adaptation of North American plants in our conditions with the preservation of decorative properties will be high. The purpose of the study was to evaluate the results of the introduction of North American woody plants planted in public areas of the city Voronezh, and the selection of the most highly decorative resistant species among them. When analyzing the results of the introduction, it is important to determine the degree of adaptation of plants to new natural and climatic conditions. The researchers propose to determine the success of the introduction on several scales at the same time, which will allow taking into account the variety of options for the introduction process. For the analysis, we selected the most common introduction scales of P.I. Lapin and S.B. Sidneva, as well as I.A. Smirnov's perspective coefficient, modified by U.F. Kuchinskaya. As the conducted studies have shown, Quercus macrocarpa and Quercus imbricaria received the highest indicators for the complex of characteristics among the analyzed species, and, therefore, we can say that they are the most promising for use in urban landscaping. Acer saccharinum and Acer rubrum can also be considered promising.

A METHOD OF SOIL BIOTESTING TO ASSESS THE RHIZOSPHERE EFFECT OF NATURAL AND ARTIFICIAL PHYTOCENOSES
Authors: Yurchuk O. , Svistova Irina
Published: June 2024

The relationship between plants and the soil microbiome has been studied from the point of view of analyzing the stimulating effect of rhizodeposites on the phytotoxic activity of soil in natural and artificial phytocenoses using the biotesting method. Biotesting makes it possible to accurately assess the positive or negative effect of plant allelopathic substances on the rhizosphere zone without spending significant time and material resources. Basically, biotesting techniques are implemented using the analysis of aqueous extract, but a more reliable assessment of soil samples is the assessment of the solid soil phase. Therefore, the most accessible method for evaluating the stimulating effect of rhizodeposites is the method of biotesting on soil plates using a test plant. The use of an indicator plant organism makes it possible to study the impact on the soil environment of a combination of factors, both positive and negative, and to make an overall assessment of the toxicity of this environment based on their changes. The results of soil biotesting allow us to develop the most effective methods of tillage to increase its fertility.

Published: June 2024

Plantings for reclamation purposes in the conditions of the Rossoshansky district of the Voronezh region form biological objects of long-term use with an ever-increasing reclamation effect. With an area of forest belts of 2009.6 hectares, the foliage of arable land is 1.50%. The purpose of the study is to identify patterns of tree growth in protective plantings and establish parameters for afforestation and the volume of forest reclamation work. In protective plantings, biometric growth indicators of species vary depending on the agrotechnical and silvicultural features of the creation, mixing patterns, and formation structure. Due to physiological processes in different parts of the transverse profile, the largest diameter at the age of 16 - 36 years in white acacia and green ash is observed in the peripheral rows, and, accordingly, the highest height in the central rows. The average increase in height in middle-aged forest belts with the participation of common elm and green ash on leached and ordinary chernozem is 0.2 - 2.2 m/year and at the age of 12-16 years a decrease in growth activity is already noted. Artificial linear plantings with a smaller width and number of rows have a greater wind-protective height. With a planting density of 5000 pcs/ha and placement of planting places of 2.5 x 0.8 m, the difference in the double width of forest belts leads to a change in the preservation of species and height indicators by 6.7 -12.0%. Mixed plantings with the participation of white acacia, green ash, and silver birch are in quite satisfactory condition. With an increase in the forest cover of arable land, an increase in agricultural crop yields is noted. The optimal parameters for arable land cover should be 3.25%.

Published: June 2024

Adventitious plants are plants that have taken root in a place that does not correspond to their area of origin due to anthropogenic impact, and therefore they are all wild species that were created only with human help, unlike native species
The results of the study of adventitious woody plants of the urban flora of the Republic of Crimea, Russia are presented. The composition of adventitious flora species has been determined, and their ecologobiological properties have been studied. 162 species of adventitious species from 49 families have been identified in the flora of the Republic of Crimea, which is about 43% of the total species composition of the peninsula.
The adventitious flora in all parts of the world is very diverse, and its expansion is a rapidly growing process that has a global character and entails a chain of negative consequences.
The scale of the adventitious component's impact on nature does not entail the need for special study of its composition, properties and development trends
A comprehensive study of the adventitious species of the Republic of Crimea seems relevant as a starting point for monitoring the invasion of adventitious species.

Authors: Nozdracheva R. , Kostennikov R.
Published: June 2024

Cherry is a fruit stone fruit crop, popular in many countries of the world and on the territory of the Russian Federation. Cherry fruits are valued for their dessert and delicate taste, high content of nutrients. It is consumed fresh and processed. Cherries are especially suitable for making compotes. Breeders have created many varieties of cherries for different soil and climatic conditions. Cherry varieties differ in color and ripening of fruits. The trees are tall, have a spreading and sparse crown, and require regular pruning.
To create cherry varieties with small-sized crowns, it is necessary to select compact crowns and propagate cherry varieties on clonal rootstocks. Scientific studies on the propagation of cherries on vegetatively propagated rootstocks indicate a decrease in the growth activity of annual seedlings in the fruit nursery, and shortening of the central trunk of seedlings (tweezing) allows you to increase the formation of side shoots at a given height and form a crown in annual cherry seedlings. It has been established that the studied cherry varieties when grafted on clonal rootstocks VSL-1 and LC-52 provide good survival in the nursery, high yield of planting material, but the growth and development of seedlings depends on variety-rootstock combinations.

THE EFFECT OF SALT STRESS ON THE CATALYTIC ACTIVITY OF γ-HYDROXYBUTYRATE DEHYDROGENASE IN THE LEAVES OF MAIZE ZEA MAYS L.
Authors: Plotnikova E. , Anohina G. , Eprintsev A.
Published: June 2024

Soil salinity is one of the main problems in agriculture, and it has a significant impact on the growth and development of agricultural crops. High salt content in the soil leads to increased osmotic pressure, which hinders the uptake of water and nutrients by the plant. This leads to changes in plant metabolism, in particular, disrupting the functioning of the Krebs cycle, which is the main source of energy for plant growth. In addition, soil salinity affects the functioning of the GABA-shunt, which plays an important role in regulating stress responses in plants. The enzyme γ-hydroxybutyratedehydrogenase (GBDH) plays an important role in the adaptation of plants to abiotic stresses. Unfortunately, the functioning of this enzyme in plant cells is still poorly understood. Therefore, we studied the effect of salt stress on the enzymatic activity of GBDH in the leaves of corn seedlings. It was shown that salt stress induces GBDH activity in the leaves of corn starting from the first hour of incubation in the stressful environment.

In the presented work, based on many years of research and generalization of surveys of the hanging birch, the issues of the modern agroecological state of the environment in which it is not always favorable not only for humans, but also for all living organisms are highlighted.
Green spaces are important in urban systems, which perform many important functions: from oxygen saturation of the air to dust and noise absorption. Being a part of urban ecosystems, trees and other plant groups fully feel the negative impact of the urban environment, especially the increase in MPC.
Modern methods of environmental monitoring make it possible to assess the state of the environment based on morphological, anatomical and other changes in the structure of green organisms, in particular leaf asymmetry.
QUANTITATIVE CHANGES IN THE CONTENT OF MIR165A microRNA IN MAIZE LEAVES UNDER IRRADIATION WITH LIGHT OF DIFFERENT WAVELENGTHS
Authors: Fedorin Dmitry , Chuykova V. , Eprintsev A.
Published: June 2024

The most important factor for the development and growth of a plant is light, which acts as the main source of energy. In addition, light regulates physiological and biochemical processes through photoreceptor systems. Studies have shown that microRNAs play a special regulatory role in the organization of cellular metabolism, regulating gene expression in various ways both at the transcriptional and post-transcriptional levels. There are a significant number of microRNAs that participate in the light-dependent mechanisms of regulation of target genes. miR165a microRNA is light-dependent, the amount of which varies depending on the state of the phytochrome system. The use of such a specific PEG 1500 coadjutor, which separates high-molecular and low-molecular RNAs during phenol-chloroform extraction, made it possible to obtain a high yield of microRNAs from the total cellular RNA. A probe and specific primers have been developed to quantify miR165a in corn leaves. It was found that the active form of phytochrome causes an increase in the concentration of the analyzed microRNA in the cells of corn leaves, which was shown using the real-time polymerase chain reaction method. A change in the light regime of light-loving plants, for example, corn, associated with a decrease in the proportion of red light in the light stream, will negatively affect the cellular regulation mediated by miR165a.
