A number of factors affect the redistribution and value of axial forces in the cores of structural slabs, such as the location and quantity of supports, the presence or absence of prestress in the structure, the shape of the base crystal of the slab, which is the forming element, and the height (thickness) of the slab, which can be varied within certain permissible limits. A change in one of these features with the rest of the parameters remaining unchanged significantly changes the stress-strain state of the structure. The paper describes the description of finite element models of a structural grid slab with a plan dimension of 12.0×24.0 m. Four models of the slab are adopted, differing only in one parameter ‒ the thickness of the structure. The following values of the structure height were adopted: 1.5 m (model No. 1), 1.3 m (model No. 2), 1.1 m (model No. 3), 0.9 m (model No. 4). The analysis and design of all models were performed, which were accepted. New profiles of the structural groups of rods were selected so that they met the check conditions for the first and second groups of limit states and the percentage of rod cross-section utilisation was as high as possible. The maximum deflections of the models after the analysis were compared. The lowest weight as an optimality criterion is the most common criterion for structures, in particular metal structures, as this criterion is quite easy to formalise. The weight of each slab model was calculated and it was found that the optimal design solution is model No. 1 with a height of 1.5 m, since only for this model the deformability is within the permissible limits. The model characterised by the lowest weight is model No. 3, but the maximum vertical deflection of this structure is greater than the maximum limit. In conclusion, the analysis of the displacements of the slab model nodes revealed that only the maximum deflection of the slab in model No. 1 does not exceed the maximum permissible deflection of 4.8 cm. The maximum deflections in models No. 2, 3, 4 exceed the maximum permissible value of the absolute deflection. Consequently, the check condition for the second group of limit states is not met in models 2, 3, and No. 4, and model No. 3, which has the lowest weight, cannot be recognised as the most effective among the others. Considering the condition of sufficient stiffness, the optimal design solution is model No. 1. The difference in weight between model No. 1 (8.9 tonnes) and model No. 3 (8.33 tonnes) with the lowest weight is 6.8 %.

Published: July 2024

More and more roads with hard cement concrete pavements are built in developed countries, including Ukraine. The production of almost all types of concrete involves the use of plasticisers. Today, polycarboxylate additives are the most effective plasticisers. However, the effect of water-reducing modifiers depends on the formulation and technological characteristics of a concrete. In the construction of hard pavements, concrete mixes with relatively low mobility are used, in which it is necessary to determine the effectiveness of various plasticisers, taking into account the type of cement. Accordingly, the purpose of the study is to establish how the strength of concrete pavements is determined by different types of plasticisers. The strength of concretes with four different plasticisers was compared. The plasticisers considered were: Polyplast SP-1 (based on a mixture of sodium salts and polyethylene of phthalate sulphuric acids); Coral ExpertSuid-5 (based on carboxylic acid polymers and esters), Coral MasterSilk (based on lignosulphonates), and Sika® Plastiment®-1230 (produced on the basis of lignosulphonates). These were added in two dosages ‒ 0.8 and 1.2% by weight of cement. The cement used was PC II/A-Sh-500 R-H in the amount of 350 kg/m3, the crushed stone was as fine as 5–20 mm, and the washed quartz sand had the fineness modulus 2.4. The mobility of all concrete mixes was S1 and depended on the composition of the concrete. It has been found that the use of Coral ExpertSuid-5 can reduce the water/cement ratio most significantly. The use of Coral MasterSilk reduces the water/cement ratio to a slightly lesser extent. SP-1 and Sika® Plastiment®-1230 have approximately the same, and the lowest, effectiveness in reducing the water demand of the mixture. At the design age, the highest strength (55.9-57.5 MPa) was observed in concrete pavements modified with Coral ExpertSuid-5 and Sika® Plastiment®-1230 plasticisers. At the age of 3 days, concretes with the Coral ExpertSuid-5 additive have the highest strength. An increase in the dosage of these two plasticisers from 0.8% to 1.2% increases the early strength of concrete, but does not change the strength at the design age. The strength of the concrete modified with the Polyplast SP-1 and Coral MasterSilk additives was lower at the early and design ages. That is, taking into account the use of mixtures of low mobility and cement PC II/A-S-500 R-H, the effectiveness of the additive based on carboxylic acid polymers in increasing the strength of concrete at the design age is approximately equal to that of the lignosulphonate-based additive.

The intricate structure of the oil rim of oil and gas deposits is a determining factor in the peculiarities of its development. The exploitation of productive formations results in the depletion of oil reserves due to the uncontrolled withdrawal of gas. The application of an unbalanced oil withdrawal and waterflooding process results in a reduction in the oil recovery factor. The article considers the issue of enhancing the efficiency of oil rims exploitation technology, with a particular focus on the research conducted into the displacement process of oil by gas agents. The authors of the article present the applicability criteria of enhanced oil recovery technologies, which serve as a basis for selecting the method of stimulation of the reservoir based on its geological and physical characteristics. Additionally, the results of the technology efficiency assessment for each reservoir are presented, along with a justification for the application of enhanced oil recovery methods. Finally, the article justifies the choice of research objects based on the application of enhanced oil recovery methods for different fields. The results of the ranking led to the identification of the criteria that justified the sites for water-gas impact testing. The following sites were identified as suitable for water-gas impact testing: BU11 2 (Urengoy oil and gas condensate field), BT11 0, BT11 (Zapolyarnoye oil and gas condensate field), BU8-9 3 (Yen-Yakhinskoye oil and gas condensate field), BU9 2 (Pestsovoye oil and gas condensate field), PK1 (Tazovskoye oil and gas condensate field), ACh3 0, ACh3, ACh4, ACh5 (Yamburg oil and gas condensate field).

Issues of practical application of the results of seismic facies analysis are of concern to subsoil users and specialists from scientific institutes in the oil and gas industry. It is not always evident what contribution this work makes to the outcome of geological modeling and what significance it has when integrating materials from areal seismic studies, geophysical well surveys andcore data. At the same time, interest in this type of work decreases as fields are drilled, although with increasing well data, the reliability of the results of seismic facies analysis increases significantly, and additional opportunities arise to search for promising and undeveloped zones of the deposit.

   In this regard, the main objective of the article is to remind the public of the importance of this component of geological modeling, to illustrate the practical applications of seismic facies analysis, and to present various approaches to seismic facies mapping.

   The article describes approaches to seismic facies analysis at different stages of exploration of promising areas and fields, taking into account 2D and 3D seismic exploration. It is noted that the use of neural networks for calculating seismic classes makes it possible to work with different input data, including volumetric cubes of digital material and two-dimensional maps constructed from the results of seismic exploration. Attention is a paid to the role of seismic facies analysis in creating geological models and assessing the resource base. An option is a shown for calculating a three-dimensional cube of lithology and reservoir properties taking into account seismic facies analysis and lithofacies analysis with a brief description of modeling algorithms. The impact of seismic facies analysis and lithofacies analysis results on the distribution of reservoirs within the three-dimensional geological model is illustrated through the example of the simulation area. Furthermore, the mapping of zones of probable claying of the productive formation is demonstrated.

The object of the study is the process of formation of the spring wheat harvest after sowing with seeds isolated at soaring speeds of 9, 10, 11 m/s. The purpose of the work is to improve the quality of seed material and spring wheat harvest based on pneumatic separation. During the research, using a Petkus K-293 laboratory pneumatic classifier, grain was separated into fractions at soaring speeds in the range of 9-11 m/s with a sampling step of 1 m/s. To determine the effect of seeds with different soaring speeds on the growth and development of plants, as well as on the yield and quality of the resulting grain, studies were carried out in the period from 2020 to 2023 on the basis of the educational and experimental agricultural station of the Altai State Agrarian University. The most common and zoned variety in the Altai region, the elite soft wheat variety Altai Zhnitsa, was chosen. Comparative sowings of spring wheat were carried out with fractions isolated at soaring speeds of 9, 10, 11 m/s. In the process of work, a qualitative and quantitative assessment of the seed material of spring wheat and its harvest was carried out, observations were also made of the phases of plant development during the growing season and the conditions of their growth. The main indicators of seed material are their specific gravity; during the processing of the results, a linear relationship between the specific gravity of seeds and their yield was observed. The technology of seed preparation by pneumatic classification can be introduced into production after additional clarifying studies on differentiating the seeding rate within one selected fraction.

Health protection of aquacultured hydrobionts faces the problem of correcting immunodeficiency states of various genesis. Immunosuppression is associated with the development of opportunistic infections. In addition, the immuno-physiological status of farmed fish is directly related to fish production and, consequently, to the economic performance of aquaculture enterprises. The use of immune-correcting drugs in aquaculture is one of the new effective methods of controlling fish diseases. One such drug is Roncoleukin (recombinant interleukin-2), which provides the cellular component of adaptive immunity. Its use in fish farming has yielded positive results in sturgeon, carp and young salmon fish. In 2023 in the cold-water basin farm of IE Romanov (Leningrad Region) on three-year old Arctic char Salvelinus alpinus (Linnaeus, 1758) the effect of the preparation “Roncoleukin” on the indices of nonspecific immunity was evaluated. As a result of the experiment, the parameters characterizing the intensity of anti-infective immunity of fish bactericidal activity of blood serum, the level of C-reactive protein, the content of circulating nonspecific immune complexes and phagocytic activity of neutrophils were studied. The study showed a high level of bactericidal activity of blood serum in control and experimental fish and, as a consequence, the absence of immunodeficient individuals. The high index of neutrophil phagocytic activity in Arctic char fed Ronkoleikin indicates the stimulating effect of this drug on the mechanisms of cellular immunity. This indirectly confirms the higher content of immune complexes and the number of individuals with a positive level of C-reactive protein in the group of experimental fish.
The new methodoly of performance testing for young horses of sport breeds

Published: July 2024

The authors proposed and approved a new method of performance test for evaluating of dressage and jumping qualities of young horses on the farm and at the inter-farm level to assess the performance inclinations of sports horses. Since the early 1980s, a performance test system has been proposed which included horse’s demonstrating under the saddle with measure of stride length at walk and trot, trot and canter style, as well as assessing jumping performance by free jumping. The changes in the economic conditions of most stud farm, the emergence of a shortage of personnel, as well as greater attention to the welfare of animals, the using of 2-year-old animals under the saddle has been practically stopped. This has confronted science and practice with the task of developing a new system for assessing young animals, which would allow them to reliably identify and evaluate their capabilities with less organizational costs. Since 2005, within the framework of cooperation with the German Hanoverian Society, first on the basis of the Stud farm Elitar, and since 2016 in the Riding Complex Maxima Park, the new type of evaluating of young horses began to be carried out with the involvement of foreign experts. This allowed authors to accumulate significant experience and propose our own methodology for testing young animals in movements and free jumps. The system was tested as part of an interbreed comparison at the exhibition “Equestrian Russia”, as well as in breeding farms in the Budennovskaya (OJSC Stud Farm named after the First Horse Army) and Hannover (LLC Private Stud Farm “Weedern”).For the convenience of assessing performance during grading, new indicators were introduced the dressage index and the jumping index with the determination of the weighting coefficients of individual characteristics. During testing of the methodology, certain patterns were discovered that allowed us to conclude that it is possible to determine specialization and subsequent assignment at 2-3 years of age. In particular, correlations were found (p<0,01) between scores for gaits in a complex of motor indicators: walk-trot 0.46, walk-gallop 0.51, trot-gallop 0.58, in a complex of jumping qualities between jumping style and assessment gallop 0.31, jumping potential and gallop 0.35, between technique and potential – 0.88. The analysis also showed the presence of significant differences between horses of different breeds. No significant differences between colts and fillies was identified.

Artificial incubation of poultry eggs makes it possible to organize year-round production of poultry products, increase productivity and reduce the number of the parent flock of poultry. In studies on incubation eggs of the parent flock of hens of the Ross-308 cross that meet the existing standards, it was found that with different air humidity in the incubator, the efficiency indicators of biotechnology change embryo development, chick hatching and egg hatchability, incubation waste and the intensity of the withdrawal of conditioned young. The optimal humidity in the incubator was in the range of 52–54 %. In this mode, the development of embryos of the first category was at the level of 62.5 %, the hatch of young animals and the hatchability of eggs amounted to 88.5 and 89.4 %, respectively, incubation waste was 4.3–7.3 % lower compared with higher or lower humidity with high intensity of hatchling and profitability of the incubation process. Deviation from the established optimum of air humidity in the incubator is accompanied by deterioration in all studied indicators of broiler reproduction.

Sem dúvida alguma vivemos hoje em um mundo digital, todavia a eletrônica que iniciou esta revolução foi a eletrônica dos sinais analógicos. Mas, afinal o que é um sinal analógico? Onde o encontramos? Dizemos que um sinal é analógico quando o mesmo pode assumir infinitos valores, mesmo dentro de uma faixa limitada, tal como o intervalo contínuo de zero a quinze volts. Se observarmos direito, veremos que a própria Natureza nos oferece sinais puramente analógicos. Por exemplo, a temperatura em um corpo não dá saltos, mas varia de forma contínua dentro de uma faixa. Em geral, dizemos que a Natureza possui um comportamento analógico uma vez que qualquer que seja a grandeza que estejamos interessados em medir, as suas variações levam um tempo finito para ocorrerem. Neste sentido, os sinais digitais, conforme veremos mais adiante, são abstrações (aproximações) matemáticas. Mesmo com esta aproximação, os sinais digitais estudados em Eletrônica digital não perdem sua importância. De forma alguma! É graças aos desenvolvimentos da Eletrônica Digital que hoje temos o computador digital e todo um conjunto enorme de outros equipamentos intrinsecamente digitais.

Published: July 2024

В сегодняшних реалиях достаточно часто встречается попытка отождествить современное епископское служение со служением епископа в апостольский период. Чаще всего в подобных высказываниях делаются ссылки на книги Священного Писания Нового Завета, а также на ранние памятники христианской письменности, в которых упоминается епископский чин. Это, в свою очередь, свидетельствует о недостаточных знаниях в данном вопросе, а также о его ограниченном освещении в русской научной литературе. Целью данного исследования было изучение епископского служения в первые четыре века и его транспозиции на протяжении указанного периода. В статье рассмотрены основные причины произошедшего изменения служения предстоятеля христианской общины. Проанализированы как внешние, так и внутренние факторы, повлиявшие на транспозицию епископского служения. Приведены примеры оценки данного служения в наиболее авторитетных памятниках христианской письменности Доникейского периода.

In today's reality, it is quite common to see attempts to identify the modern episcopal ministry with the ministry of the bishop in the apostolic period. Most often in such statement’s references are made to the books of Holy Scripture of the New Testament, as well as to the earliest monuments of Christian writing, in which the episcopal rank is mentioned. This, in turn, indicates insufficient knowledge of this issue, as well as its limited coverage in Russian scientific literature. The purpose of this study was to examine the episcopal ministry in the first four centuries and its transposition throughout the period. The article considers the main reasons for the change in the ministry of the primate of the Christian community. Both external and internal factors that influenced the transposition of the episcopal ministry are analyzed. Examples of the evaluation of this ministry in the most authoritative monuments of Christian writing of the pre-Nicene period are given.
Easter Gospel Readings in the Jerusalem Divine Service in the V–VII Cent.
Authors: Сурцев Сергей
Published: July 2024

Статья посвящена изучению того, как изменялось восприятие праздника Пасхи в Иерусалимском богослужении на примере пасхальных евангельских чтений Иерусалимской лекционарной системы в V–VII вв. Рассмотрение поставленной проблемы позволяет выявить ценные сведения о смыслах главного христианского праздника в богослужебной практике Востока. Данная тема часто обходится стороной отечественными исследователями. За основу взяты два источника, отражающие богослужебную практику Святого Города: армянский (V в.) и грузинский (VIII в.) Лекционарии. В процессе исследования было выяснено, что в V в. сформировавшийся с ранних времён христианства смысл Пасхи как переход от Смерти к Жизни трансформировался: события пасхальной ночи стали восприниматься не как тайна Искупления, а как конкретное событие Воскресения. Толчком этому послужила тенденция того времени в исторической привязке евангельского отрывка к празднуемому событию.

The article is devoted to the study of the changing perception of Easter in the Jerusalem Divine Service: the Easter Gospel readings of the Jerusalem lectionary system in the V–VII centuries case study. Consideration of this matter allows to reveal valuable information about the meanings of the most important Christian feast in Eastern liturgical practice. The topic has been little studied by Russian scholars. Two sources reflecting the Holy City liturgical practice were taken as a basis for the study: Armenian (V century) and Georgian (VIII century) Lectionaries. In the course of the research, it was found out that in the V century the meaning of Easter, which had been formed since the early times of Christianity as a transition from Death to Life, was transformed: the events of Easter night began to be perceived not as a mystery of Redemption, but as a specific event of the Resurrection. The trend of that time to make a historical connection between the Gospel passage to the event being celebrated have provided the impetus for this.
Successions: Difference and similarity of general ecological and hydrobiological views
Authors: Rozenberg G. S. , Zinchenko T. D.
Published: July 2024

The article discusses the features of what is called “hydrobiological succession of flowing waters” in modern scientific literature. These features are associated with the dual nature of such changes: temporal (classical, inherent in a given geographical point) and spatial (“longitudinal”) successions (in the latter case, it is more accurate to speak of “clinal” changes – ecoclines, topoclines, etc.). This allows, on the one hand, to correct modern knowledge about flowing waters, and, on the other hand, to contribute to a better understanding of succession as a general ecological concept.

Pneumonia is a respiratory disease that affects more than 287,000 children under five in Indonesia, with 444 deaths among those under five. One of the factors causing pneumonia is exposure to tobacco smoke in the home. This study aimed to describe the association between exposure to indoor tobacco smoke and the incidence of pneumonia among under-fives in Indonesia. This study method was a systematic review using articles from national and international journal databases. Databases used included Google Scholar, Garuda Portal, Scopus, Science Direct, ProQuest, and Springer Link. Articles in this study used the case-control method, published between 2013 and 2023, and focused on the association between indoor tobacco smoke exposure and under-five pneumonia incidence. There were 15 articles reviewed in this study. From the review of 15 articles, factors of exposure to secondhand smoke found in the home include the smoking habits of family members, the presence of family members who smoke, the number of family members who smoke, the location of smoking in the house, the presence of secondhand smoke exposure in the house, the number of cigarettes consumed by family members, the togetherness of infants with smokers, and the smoking status of the father. Most articles show a significant association between exposure to tobacco smoke in the home and the incidence of under-five pneumonia, so it can be concluded that exposure to tobacco smoke in the house is associated with pneumonia in under-fives.
