Authors: Kilin Grigory , Kavalerov Boris , Suslov Artem , Tyatenkov Ilya
Published: August 2023

This article focuses on the application of pre-training methods in the task of synthesizing surrogate models. The article emphasizes that pre-training significantly improves the accuracy of surrogate models and speeds up their creation process. The authors examine pre-training’s impact on various aspects of surrogate modeling of a gas turbine unit that is part of a gas turbine electric power station, such as reducing computational costs, improving the approximation of complex processes, and optimizing the model synthesis procedure. The work demonstrates specific examples that clearly show how the use of pre-training can significantly improve the performance of surrogate models and optimize the development process. Thus, the authors convincingly argue that pre-training is a key tool for increasing the efficiency of surrogate modeling, capable of significantly reducing the time, costs, and efforts required for the development and use of surrogate models in the energy sector.

Authors: Lyubov Viktor , Popov Anatoly
Published: August 2023

Combined heat and power plants (CHPPs) allow for significant savings in primary energy resources and a reduction in environmental pollution. Mostly it is carried out using steam turbines. However, in the eighties of the twentieth century, a new promising direction in the development of cogeneration appeared. These are plants operating on the organic Rankine cycle (ORC). An analysis of energy innovations abroad is required for the development and adaptation of this direction to Russian realities. Therefore, an analysis of the energy and environmental efficiency of high-moisture biofuels and biofuel mixtures with high ash content was carried out in boilers operating as part of a CHP using ORC technology and traditional steam turbine plants. Some recommendations for the innovative development of small and medium-scale power generation were proposed.

Updating the petrophysical model of a thin-layered clay reservoir, taking into account the identified lithofacies features
Authors: Agishev Ernest , Andreev Vadim , Dubinsky Gennady
Published: August 2023

The article presents a study on the establishment of geological and facies conditions for the formation of a sandy-silty-clayey reservoir based on core analysis and linking the information obtained with neighboring areas. Previously used petrophysical relationships were generalized with underlying objects composed of thick monolithic sandstones and did not allow correctly assessing the properties of the reservoir under consideration. The work made it possible to clarify the idea of lithofacies features to substantiate their own petrophysical dependencies, which make it possible to differentiate thin-layered clay reservoirs in the section and determine their properties. The results obtained during the study made it possible to refine the petrophysical model, previously generalized to all the layers of the group. The revision of the boundary values and dependencies helped to justify the increase in reservoir oil reserves and became the basis for subsequent work to increase the profitability of putting the facility into commercial development.
Influence of the content of dispersed fillers of various nature in polyvinylidene fluoride on its structural parameters and thermal conductivity
Authors: Rakhmankulov A A
Published: August 2023

In this work, a comprehensive study of the effect of graphite and bronze particles on the structure and thermal conductivity of polyvinylidene fluoride (PVDF) was carried out. Based on the experiments carried out, it was found that at the limit of a relatively small concentration of bronze, the melting point of PVDF exceeds, and this was confirmed by an increase in the longitudinal dimensions of the crystallites. With relatively small amounts of fillers contained in the polymer composite materials (PCM, it was written that the change in thermal conductivity occurs mainly due to changes in the polymer structure. It was found out that the change in the structure of the polymer component in the compound and the thermal conductivity largely depends on the nature of the fillers.

Authors: Agzamov A Kh , Rakhmonkulov M T , Omonov S P , Sultonov N N
Published: August 2023

The results of statistical processing of data from 97 wells put into re-operation, after their long downtime due to flooding, are presented. In which, depending on the geological and physical conditions and the state of development of oil deposits, different results are obtained. With an average initial oil flow rate of 1.12 tons/day in reservoir-vaulted deposits with low-viscosity oil in the Fergana oil and gas region - 0.5 tons/day, in reservoir-arch deposits with high-viscosity oil in the Surkhandarya oil and gas region - 0.97 tons/day, in sub-gas deposits of the Bukhara-Khiva region - 2.5 tons/day. By assessing the informativeness of geological, physical and technological factors using the Kulbak method, the degree of their influence on the initial oil flow rate of wells after their re-commissioning was established. Taking into account the degree of influence of the factors considered, it is recommended to put into re-operation wells located in the arched part of the reservoir, having the highest effective oil-saturated thicknesses, in areas with a low oil recovery factor and a lower degree of reduction in initial reservoir pressure, as well as watered in a short period of operation.
Design of a combined cube of seismic data acquired in areas of complicated relief by use of various seismic source types
Authors: ogli Ahmadov Tofig Rashid
Published: August 2023

The paper gives brief information on the study area with attention focused mainly on complex surface seismic and geological environment, stipulating the use of 3D seismic survey in this area. As the area features complicated relief, the sources and receivers have been chosen individually for each location of the survey. Seismic energy sources generated various seismic oscillations and this complicated the design of combined 3D cube for the whole study area. By use of modeling we have reduced all oscillations to the minimal-phased form. The next stage of processing consisted in use of shifts of time sections for combination of seismic boundaries acquired for various parts of the area: onshore, offshore, swampy areas. Thus, applying the standard procedures it was possible to design combined 3D cube.

Authors: Dvinin Dmitry , Davankov Aleksey , Plaksina Anna , Yusifov Elman
Published: August 2023

The article provides the author’s model for assessing the level of sustainability in the development of a region due to an increase in the share of alternative energy sources and on the premise of maintaining a carbon balance. It was taken into account that the possibility of maintaining the carbon balance in the region is greatly influenced by agricultural activities and landscape features of the region. Thus, in some regions it is necessary to allocate additional areas of ecosystems with a special nature management regime to maintain the carbon cycle. The model generated was tested on the example of the regions of the Ural Federal District of the Russian Federation. It has been established that carbon dioxide emission from anthropogenically disturbed territories is present in four regions of the district: Sverdlovsk (17.9 million tons), Chelyabinsk (45.04 million tons), Kurgan (40.9 million tons) and Tyumen (13.03 million tons) regions. Thus, even if the share of renewable energy in the energy balance increases to 37-93%, and the general balance is achieved, the carbon cycle is still disrupted. In order to preserve it, additional inclusion of up to 8.5-57.4% of the region territories into the special nature management regime is required.

Authors: Melikhov Vladimir , Melikhov Oleg , Yakush Sergey , Konovalov Oleg
Published: August 2023

One of the possible consequences of a severe accident at a nuclear power plant with a pressurized water reactor is a steam explosion that occurs as a result of the interaction of a high-temperature melt of core materials with water and can lead to the failure of the containment. The paper considers the initial stage of the steam explosion (premixing of the melt with water) under the stratified geometry. The key phenomenon leading to premixing is the dynamic effect of a collapsing vapor bubble in a liquid on the melt surface. The influence of a vapor film located near a melt surface on the dynamics of a vapor bubble is considered. The Kelvin impulse is used as the main criterion characterizing the dynamic effect of a collapsing bubble on the liquid-vapor interface and on the melt surface. The influence of all the main parameters on the Kelvin impulse was numerically studied. Based on the calculations carried out on the plane of the parameters “film thickness - vapor density”, the region of the dynamic impact of the collapsing bubble on the surface is determined. The greatest impacts are observed for thin films of vapor having a high density.

Authors: Kornilov Dmitry , Zimin Yury , Alekhina Irina , Kornilova Aliya
Published: August 2023

The rate constants of the Diels-Alder reaction of 9,10-dimethylanthracene with tetracyanoethylene, 4-phenyl-1,2,4-triazoline-3,5-dione, maleic anhydride, and N-phenylmaleimide in solution have been determined. It was found that tetracyanoethylene and 4-phenyl-1,2,4-triazoline-3,5-dione can react instantly with 9,10-dimethylanthracene, which is a representative of toxic polycyclic aromatic hydrocarbons. The kinetics of the reactions of 9,10-dimethylanthracene with tetracyanoethylene and N-phenylmaleimide in the solid phase without solvent has been studied. The rate of these reactions in the solid phase appeared to be significantly lower than that of the same reactions in the solution, since the rate of reactions in the solid phase strongly depends on the rate of renewal of contacts between the reagent molecules. The data obtained can be useful for the purification of water bodies and soil from polycyclic aromatic hydrocarbons.

Authors: Baylagasov Leonid , Kapitonova Irina
Published: August 2023

In this article are examined the issues of preserving the natural environment of the Altai Republic in the context of the agro-industrial complex development. It is shown that agriculture played a leading role in the economy of the region both in the Soviet and post-Soviet periods. The main factors of the impact of the agro-industrial complex on the natural environment of the region are associated with the fencing of maral nurseries, arable lands and hay lands, and, accordingly, with the violation of the migration routes of ungulates. The chemicalization of agriculture and overgrazing of livestock in some areas have a certain impact on the flora and fauna, water bodies and soil cover. At present, in general, the development of the agro-industrial complex does not have a significant impact on the natural environment of the region.

Authors: Yakutin Mikhail V , Andrievskii Vladislav S
Published: August 2023

The analysis of the state of the destructive block in gray forest soils in the Novosibirsk region was carried out. Forest, meadow under pasture and vegetable agrocenosis were selected as the objects of the study. Soil-zoological and soil-microbiological methods were used in the work. The biomass of soil microorganisms, basal respiration, metabolic coefficient, species richness and the total numbers of oribatid mites in soils were studied. Strong changes in the studied parameters in soils with different agricultural uses, compared with the soil under the forest, are demonstrated. With the deforestation and the transformation of the formed grass ecosystem to pasture, all the studied indicators decrease. When the grass ecosystem is plowed and the soil is used for a long time as an agrocenosis, a further decrease in microbiological and zoological indexes is observed. The conclusion is made about the possibility of applying the methods used in the practice of ecological monitoring of gray forest soils is made.

Authors: Stolpovskaya Elena , Sukhovnina Viktoriya , Aksamentova Evgeniya , Kupchinsky Aleksandr , Stom Devard
Published: August 2023

The toxic effects of Fe2+ ions and resorcinol on Lemna minor in their joint presence in the aquatic environment were studied. The test response in the bioassay of solutions of Fe2+, resorcinol, and their mixtures was a violation of the permeability of duckweed membranes. This parameter was estimated from the change in the electrical conductivity of the aquatic medium in which the plant was placed, exposed to the toxicant in the acute experiment (30 min). It was found that the addition of both an equinormal concentration of Fe(II) (0.1n) and a five-fold deficiency (0.02n) to a 0.1n solution of resorcinol reduced the toxicity of resorcinol. Most likely, the effect obtained can be achieved by the formation of a new, less toxic compound (probably of a complex nature). The test used in the work, based on the assessment of the permeability of cell membranes under the action of toxicants, once again proved to be a promising tool for analyzing the combined toxicity of phenolic compounds and metal ions in relation to plant organisms.

Authors: Khalbekova H U
Published: August 2023

The largest number of plant cover species on saline soils of Uzbekistan belongs to the family Chenopodiaceae Vent. Plant origin is a promising and accessible source for isolating substances containing amino acids. In this regard, we conducted studies on the study of the amino acid and elemental composition of Atriplex aucheri Moq. plants and Atriplex tatarica L. The ability to withstand the type of stress factors is necessary and survival in this environment requires a profound restructuring of plant metabolism, photosynthesis and transpiration, as well as the biosynthesis of adaptogenic substances. Therefore, these plants are potential candidates for the creation of new biologically active substances, stress-protective combinations of macro and microelements, which may be promising for further biotechnological, agricultural and biomedical use. As a result of the analysis, 20 free amino acids were identified in the studied species of the genus Atriplex, of which 10 are essential - threonine, arginine, valine, methionine, isoleucine, histidine, tryptophan, phenylalanine, lysine, leucine. Comparison of the content of amino acids showed that the amount of methionine was the highest in both species.

Update on Endovascular Therapy for Fibroids and Adenomyosis
Authors: Ozen Merve , Patel Ronak , Hoffman Mark , Raissi Driss
Published: August 2023

Uterine fibroids and adenomyosis are prevalent benign neoplasms that can lead to serious deleterious health effects including life-threatening anemia, prolonged menses, and pelvic pain; however, up to 40% of women remain undiagnosed. Traditional treatment options such as myomectomy or hysterectomy can effectively manage symptoms but may entail longer hospital stays and hinder future fertility. Endovascular treatment, such as uterine artery embolization (UAE), is a minimally invasive procedure that has emerged as a well-validated alternative to surgical options while preserving the uterus and offering shorter hospital stays. Careful patient selection and appropriate techniques are crucial to achieving optimal outcomes. There have been advancements in recent times that encompass pre- and postprocedural care aimed at enhancing results and alleviating discomfort prior to, during, and after UAE. Furthermore, success and reintervention rates may also depend on the size and location of the fibroids. This article reviews the current state of endovascular treatments of uterine fibroids and adenomyosis.

Labial varices are commonly seen in women with varicose veins of the pelvis. Initial management is conservative management since labial varies typically resolve, particularly in pregnant patients following delivery. Varices can be seen also in association with pelvic varices in the pelvic venous disease spectrum. Sclerotherapy is often the management. This article reviews the presentation and treatment of patients with labial varices, with a focus on interventional radiologic management.
Proposed Model to Improve Acute Stroke Care in Central India
Authors: Sharma Pankaj
Published: August 2023

There is an urgent need to develop a national program and allocation of resources to improve stroke care in India. Management of stroke requires a multidisciplinary approach and close collaboration not only among physicians from different specialties but also among paramedical personnel and patient transport services. Here we propose a healthcare model of providing acute stroke therapies to patients in central India to minimize the wide supply mismatch we face in providing adequate care to our patients. Observations and the proposed model presented below were based on personal experience and a review of the literature on stroke care available in central India.
Structures and solvent effects on the 1H and 13C NMR chemical shifts of the family of three pro-lithospermate molecules: DFT study
Authors: Hadidjatou Hamadou , Holtomo Olivier , Motapon Ousmanou
Published: August 2023

The solvent effects on the structures and nuclear magnetic resonance spectroscopy of a series of three pro-lithospermate molecules are studied. These molecules include methyl pro-lithospermate, ethyl pro-lithospermate, and n-butyl pro-lithospermate, which exhibit enantiomers and diastereoisomers. The trans-oriented enantiomers were observed by Yu et al. [Nat. Prod. Res. 31(21), 2505–2512 (2017)] and are the subject of the present study. The density functional theory was validated using the gauge-including atomic orbital/B3LYP-D3BJ/6–31++G(d,p) and continuous set of gauge transformation (CSGT)/the long-range corrected Tao, Perdew, Staroverov, and Scuseria’s τ-dependent gradient-corrected correlation-exchange functional (LC-TPSS)TPSS/cc-pVTZ methods. The chemical shifts of 1H and 13C were calculated in dimethylsulfoxide (DMSO), methanol, and water. It turns out that solvent effects are weak on the geometrical parameters (bond lengths and bond angles). The harmonic oscillator model of the aromaticity index was used to calculate the aromaticity of the subunit rings. With regard to the available experimental results, the chemical shifts of 1H and 13C are reproduced better by B3LYP-D3BJ/6–31++G(d,p) than by LC-TPSSTPSS/cc-pVTZ in the DMSO medium. The solvent effects are significant on the 13C chemical shift, mostly for protic solvents, and insignificant on 1H. The vicinal spin–spin coupling constants of protons were calculated. The coupling constant of trans-olefinic and ortho-aromatic protons fits well with the experiment.
Peripheral vision and challenging invisibilities
Authors: Freeth Peter Jonathan
Published: August 2023

This article presents a discussion of the theoretical and methodological challenges posed by digitization
processes and born-digital sources within translation and translator studies research, particularly in archival contexts. It
begins by demonstrating how the digitization of archives and source materials remains an undertheorized issue in translation
contexts, as well as the need to understand how digitization allows new forms of “peripheral vision” across our research and
publication processes. Subsequently, the article problematizes the archiving and use of born-digital sources to research
translation and translators, particularly in terms of issues surrounding data collection, access and ethics. In doing so, this
article argues that care must be taken to properly understand and preserve the digital sources that will enable archival research
in the future, whilst emphasizing the new opportunities presented by digitized and born-digital sources to challenge the
invisibility of translation and translators within many of the world’s archives and histories.

Authors: Wah Leo Kwee , Takayama Ken , Adachi Toshikazu , Kawakubo Tadamichi , Dixit Tanuja
Published: August 2023

A design of a compact hadron driver for future cancer therapies based on the induction synchrotron concept is given. In order to realize a slow extraction technique in a fast cycling synchrotron, which allows the energy sweep beam scanning, the zero momentum-dispersion D(s) region and high flat D(s) region are necessary. The present design meets both requirements. The lattice has the two-fold symmetry with a circumference of 52.8 m, 2 m-long dispersion-free straight section, and 3 m-long large flat dispersion straight section. Assuming a 1.5 T bending magnet, the ring can deliver heavy ions of 200 MeV/au at 10 Hz. Details of the lattice parameters and orbit correction approach and method are discussed.
X-ray imaging of an industrial microcontroller sample using dual-energy technique
Authors: Razali Azhani Mohd , Yahya Roslan , Jamaludin Maziah
Published: August 2023

In a conventional single-energy X-ray imaging technique, the information obtained from the examined object are often not sufficient for precise characterization. Hence, this study was designed to assess whether the dual-energy imaging technique would be a good alternative to the conventional method and can be used to improve the output image. An electronic microcontroller was chosen as the sample due to its complex inner structure. It was scanned using the X-ray micro computed tomography (micro-CT) scanner at two different energy levels: 60kVp and 100kVp. Dual-energy image processing method was applied to the acquired image and the results were compared to the single-energy image in term of contrast and image quality. The combined information from dual-energy scan at 60kVp and 100kVp was able to visualize the sample’s internal structure (raised surface). By comparison, the single-energy imaging technique was only capable at producing shadow image. The resolution of the dual-energy image, however, was much lower due to the loss of data….

Philosophy and Platonism in Fronto’s Correspondence
Authors: Costantini Leonardo
Published: August 2023

This chapter focuses on the references and allusions to Plato in Fronto’s epistolary corpus, especially in his correspondence with Marcus Aurelius, to whom Fronto taught rhetoric. Attention will be paid to Fronto’s engagement with philosophy and his high esteem for Plato and (Middle) Platonism: Plato symbolizes the perfect synthesis between philosophy and rhetoric, which Fronto measures against the fallacy of Stoic dialectic, and Platonic elements play an important function in several letters.
Receptions and appropriations of Platonic myth: Dio, Plutarch, and Aristides between literary fashion and philosophical exegesis
Authors: Trapp Michael
Published: August 2023

This chapter examines the Platonizing myths of Dio Chrysostom, Plutarch, and (to a lesser degree) Aelius Aristides, in the light of our evidence for both the philosophical and the literary-rhetorical reception of Plato’s own myths. It argues that, while reflections of the development of Platonism as a systematic philosophy can be detected in them, it can be hard and may in some respects be pointless to disentangle this philosophical input neatly from the ramifications of the literary-rhetorical reception.
Ploidy Variation and Its Implications for Reproduction and Population Dynamics in Two Sympatric Hawaiian Coral Species
Authors: Stephens Timothy G , Strand Emma L , Putnam Hollie M , Bhattacharya Debashish
Published: August 2023

Standing genetic variation is a major driver of fitness and resilience and therefore of fundamental importance for threatened species such as stony corals. We analyzed RNA-seq data generated from 132 Montipora capitata and 119 Pocillopora acuta coral colonies collected from Kāneʻohe Bay, Oʻahu, Hawaiʻi. Our goals were to determine the extent of colony genetic variation and to study reproductive strategies in these two sympatric species. Surprisingly, we found that 63% of the P. acuta colonies were triploid, with putative independent origins of the different triploid clades. These corals have spread primarily via asexual reproduction and are descended from a small number of genotypes, whose diploid ancestor invaded the bay. In contrast, all M. capitata colonies are diploid and outbreeding, with almost all colonies genetically distinct. Only two cases of asexual reproduction, likely via fragmentation, were identified in this species. We report two distinct strategies in sympatric coral species that inhabit the largest sheltered body of water in the main Hawaiian Islands. These data highlight divergence in reproductive behavior and genome biology, both of which contribute to coral resilience and persistence.
The Ka /Ks and πa /πs Ratios under Different Models of Gametophytic and Sporophytic Selection

Published: August 2023

Alternation of generations in plant life cycle provides a biological basis for natural selection occurring in either the gametophyte or the sporophyte phase or in both. Divergent biphasic selection could yield distinct evolutionary rates for phase-specific or pleiotropic genes. Here, we analyze models that deal with antagonistic and synergistic selection between alternative generations in terms of the ratio of nonsynonymous to synonymous divergence (Ka/Ks). Effects of biphasic selection are opposite under antagonistic selection but cumulative under synergistic selection for pleiotropic genes. Under the additive and comparable strengths of biphasic allelic selection, the absolute Ka/Ks for the gametophyte gene is equal to in outcrossing but smaller than, in a mixed mating system, that for the sporophyte gene under antagonistic selection. The same pattern is predicted for Ka/Ks under synergistic selection. Selfing reduces efficacy of gametophytic selection. Other processes, including pollen and seed flow and genetic drift, reduce selection efficacy. The polymorphism (πa) at a nonsynonymous site is affected by the joint effects of selfing with gametophytic or sporophytic selection. Likewise, the ratio of nonsynonymous to synonymous polymorphism (πa/πs) is also affected by the same joint effects. Gene flow and genetic drift have opposite effects on πa or πa/πs in interacting with gametophytic and sporophytic selection. We discuss implications of this theory for detecting natural selection in terms of Ka/Ks and for interpreting the evolutionary divergence among gametophyte-specific, sporophyte-specific, and pleiotropic genes.
