Published: December 2023

Peritoneal cancer index (PCI) is the surgical variable most commonly used to quantify the extent of peritoneal metastases for pseudomyxoma peritonei (PMP) patients. The present study aimed to investigate the agreement between CT predicted and surgical PCI by the Bland–Altman method for PMP of appendiceal origin. A total of 167 PMP patients of appendiceal origin were included between 2016 and 2021. Bland–Altman analysis was performed for both total PCI and selected PCI (regions 2 + 9–12). After the Bland–Altman plot was drawn, the mean bias and its 95% limit of agreements (LoAs) was quantified. Besides, the correlation coefficients between CT-PCI and surgical PCI were also been calculated. The Bland–Altman plot showed the mean bias ± SD between total CT-PCI and surgical PCI as 0.431 ± 3.005, with the LoAs from − 5.459 to 6.321. There were nine points of difference in total PCI exceeded the 95% LoAs, with the rate of 5.39% (9/167). As for selected CT-PCI, Bland–Altman plot showed the mean bias ± SD between selected CT-PCI and surgical PCI as − 0.287 ± 1.955, with the LoAs from − 4.118 to 3.544. There were ten points of difference in selected PCI exceeded the 95% LoAs, with the rate of 5.99% (10/167). The Spearman's rank correlation coefficient between total CT-PCI and surgical PCI was 0.911, P < 0.001, as for selected CT-PCI and surgical PCI, the coefficient was 0.909, P < 0.001. Although there was a strong correlation for both total and selected CT-PCI with surgical PCI, however, the agreement is still not good in Bland–Altman analysis, which suggested that CT-PCI cannot predict surgical PCI accurately even in professional PMP treatment centers. In brief explanation, CT makes it difficult to distinguish the borderline between tumor tissue and mucus and to detect tumor lesions in the small intestine regions, which caused overestimation or underestimation by CT-PCI. In the future, a multiple linear regression model based on CT-PCI might accurately predict surgical PCI preoperatively.

A set of high-quality pan-genomes would help identify important genes that are still hidden/incomplete in bird reference genomes. In an attempt to address these issues, we have assembled a de novo chromosome-level reference genome of the Silkie (Gallus gallus domesticus), which is an important avian model for unique traits, like fibromelanosis, with unclear genetic foundation. This Silkie genome includes the complete genomic sequences of well-known, but unresolved, evolutionarily, endocrinologically, and immunologically important genes, including leptin, ovocleidin-17, and tumor-necrosis factor-α. The gap-less and manually annotated MHC (major histocompatibility complex) region possesses 38 recently identified genes, with differentially regulated genes recovered in response to pathogen challenges. We also provide whole-genome methylation and genetic variation maps, and resolve a complex genetic region that may contribute to fibromelanosis in these animals. Finally, we experimentally show leptin binding to the identified leptin receptor in chicken, confirming an active leptin ligand-receptor system. The Silkie genome assembly not only provides a rich data resource for avian genome studies, but also lays a foundation for further functional validation of resolved genes.

Published: December 2023

In China, several problems were common in the telemedicine systems, such as the poor network stability and difficult interconnection. A new telemedicine system jointly driven by multinetwork integration and remote control has been designed to address these problems. A multilink aggregation algorithm and an overlay network for telemedicine system (ONTMS) were developed to improve network stability, and a non‐intervention remote control method was designed for Internet of Things (IoT) devices/systems. The authors monitored the network parameters, and distributed the questionnaire to participants, for evaluating the telemedicine system and services. Under a detection bandwidth of 8 Mbps, the aggregation parameters of Unicom 4G, Telecom 4G, and China Mobile 4G were optimal, with an uplink bandwidth, delay, and packet loss ratio (PLR) of 7.93 Mbps, 58.80 ms, and 0.06%, respectively. These parameters were significantly superior to those of China Mobile 4G, the best single network (p < 0.001). Through the ONTMS, the mean round‐trip transporting delay from Beijing to Sanya was 76 ms, and the PLR was 0 at vast majority of time. A total of 1988 participants, including 1920 patients and 68 doctors, completed the questionnaires. More than 97% of participants felt that the audio and video transmission and remote control were fluent and convenient. 96% of patients rated the telemedicine services with scores of 4 or 5. This system has shown robust network property and excellent interaction ability, and satisfied the needs of patients and doctors.
Investigating the long secondary period phenomenon with the ASAS-SN and Gaia data
Authors: Pawlak Michał , Trabucchi Michele , Eyer Laurent , Mowlavi Nami
Published: December 2023

Aims. The aim of this work is to create a complete list of sources exhibiting a long secondary period (LSP) in the ASAS-SN catalog of variable stars, and analyze the properties of this sample compared to other long period variables without an LSP.

Methods. We used the period-amplitude diagram to identify the 55 572 stars showing an LSP, corresponding to 27% of the pulsating red giants in the catalog. We used astrometric data from Gaia DR3 and spectroscopic data provided by the APOGEE, GALAH, and RAVE surveys to investigate the statistical properties of the sample.

Results. We find that stars displaying an LSP have a spatial distribution that is more dispersed than that of the non-LSP giants, suggesting that they belong to an older population. Spectroscopically derived ages seem to confirm this. The stars with an LSP also appear to be different in terms of the C/O ratio from their non-LSP counterparts.

One of the most well-known extragalactic sources in the sky, quasar3C 454.3, shows a curved parsec-scale jet that has been exhaustively monitored with very-long-baseline interferometry (VLBI) over the recent years. In this work, we present a comprehensive analysis of four years of high-frequency VLBI observations at 43 GHz and 86 GHz, between 2013–2017, in total intensity and linear polarization. The images obtained from these observations enabled us to study the jet structure and the magnetic field topology of the source on spatial scales down to 4.6 parsec in projected distance. The kinematic analysis reveals the abrupt vanishing of at least four new superluminal jet features in a characteristic jet region (i.e., region C), which is located at an approximate distance of 0.6 milliarcsec from the VLBI core. Our results support a model in which the jet bends, directing the relativistic plasma flow almost perfectly toward our line of sight, co-spatially with the region where components appear to stop.

Published: December 2023

The shapes of galaxies, their outer regions in particular, are important guideposts to their formation and evolution. In this work, we report on the discovery of strongly box-shaped morphologies of the otherwise well-studied elliptical and lenticular galaxies NGC 720 and NGC 2768 from deep imaging. The boxiness is strongly manifested in the parameter shape A4/a of −0.04 in both objects, and significant center shifts of the isophotes of ∼2–4 kpc are also seen. One reason for such asymmetries commonly stated in the literature is a merger origin, although the number of such cases is still sparse, and the exact properties of the individual boxy objects are highly diverse. Indeed, for NGC 2768, we identify a progenitor candidate (dubbed “Pelops”) in the residual images, which appears to be a dwarf satellite that is currently merging with NGC 2768. At its absolute magnitude of Mr of −12.2 mag, the corresponding Sersic radius of 2.4 kpc is more extended than those of typical dwarf galaxies from the literature. However, systematically larger radii are known to occur in systems that are in tidal disruption. This finding is bolstered by the presence of a tentative tidal stream feature on archival GALEX data. Finally, further structures in the fascinating host galaxy include rich dust lanes and a vestigial X-shaped bulge component.
Cosmological constraints from the abundance, weak lensing, and clustering of galaxy clusters: Application to the SDSS
Authors: Fumagalli A. , Costanzi M. , Saro A. , Castro T. , Borgani S.
Published: December 2023

Aims. The clustering of galaxy clusters is a powerful cosmological tool. When it is combined with other cosmological observables, it can help to resolve parameter degeneracies and improve constraints, especially on Ωm and σ8. We aim to demonstrate its potential in constraining cosmological parameters and scaling relations when combined with cluster counts and weak-lensing mass information. As a case study, we use the redMaPPer cluster catalog derived from the Sloan Digital Sky Survey (SDSS).

Methods. We extended a previous analysis of the number counts and weak-lensing signal by the two-point correlation function. We derived cosmological and scaling relation posteriors for all possible combinations of the three observables to assess their constraining power, parameter degeneracies, and possible internal tensions.

Results. We find no evidence for tensions between the three data sets we analyzed. We demonstrate that the constraining power of the sample can be greatly improved by including the clustering statistics because this can break the Ωm − σ8 degeneracy that is characteristic of cluster abundance studies. In particular, for a flat ΛCDM model with massive neutrinos, we obtain Ωm = 0.28 ± 0.03 and σ8 = 0.82 ± 0.05, which is an improvement of 33% and 50% compared to the posteriors derived by combining cluster abundance and weak-lensing analyses. Our results are consistent with cosmological posteriors from other cluster surveys, and also with Planck results for the cosmic microwave background (CMB) and DES-Y3 galaxy clustering and weak-lensing analysis.

Climate impacts on vines in the upper Douro valley: Cold air pooling and unprecedented rainfall
Authors: Sanderson Michael G. , Teixeira Marta , Fontes Natacha , Silva Sara , Graça António
Published: December 2023

Climate is arguably one of the most important factors determining the quality of wine from any given grapevine variety. This study focuses on climate impacts on vines in the upper Douro Valley, which is one of the most important viticultural regions of northern Portugal. Two different phenomena are studied: cold air pooling and unprecedented rainfall totals. Cold-air pools can have several different impacts on viticulture, including timing of budbreak, final grape quality and yields. Cold pools were studied using high time resolution data from two weather stations located in the upper Douro valley. High rainfall during late spring (April to June) can promote growth of the vines but increases the risk of fungal disease. High rainfall during harvest time (August to October) also bears the potential for severe operational disruption and heavy economic losses. The probability of unprecedented rainfall totals in spring and the harvest season over wine-growing regions of northern Portugal has been assessed using an ensemble of decadal hindcasts and three different gridded precipitation datasets. The probability of a precipitation event with unprecedented totals was low (less than 0.04), although such an event would be highly damaging to the vines. A year similar to 1993, when both seasons were exceptionally wet, would be expected to occur, on average, just once in the next 70-80 years in the current climate.

Published: December 2023

La variedad Tannat desde el punto de vista del aroma, resulta una variedad neutra pero capaz de aportar precursores aromáticos que son de interés en la elaboración de vinos de guarda. Los principales precursores aromáticos presentes son compuestos glicosidados y carotenoides. Durante 3 vendimias consecutivas se estudió el contenido de precursores aromáticos de 8 clones comerciales de Tannat (ENTAV-INRA: 398, 399, 472, 474, 475, 717, 794 Y 944). En base a los resultados obtenidos se seleccionaron los clones 717 y 474 por su alta y baja performance en la producción de precursores glicosidados. En la siguiente vendimia se estudió el comportamiento de precursores glicosidados (SPE-GC-MS) y carotenoides (HPLC-DAD) en los clones seleccionados durante 4 estadíos de madurez de la uva, donde se identificaron 14 xantofilas y 1 caroteno. Se encontraron diferencias significativas en el contenido de carotenoides entre los dos clones estudiados a lo largo del período de maduración. Mientras que su degradación no presentó diferencias significativas. Conjuntamente se identificaron 10 norisoprenoides glicosidados en la uva de los clones estudiados pero el contenido de estos no presentó diferencias significativas entre los clones durante está vendimia. Las diferencias entre los clones 717 y 474 son tales que no se expresan todos los años teniendo variabilidad con el año y donde el clima juega un rol fundamental.
Do Totiviruses of the veil of Flor yeasts provide an evolutionary advantage?

Published: December 2023

The main objective of this work was to isolate and characterize viruses that infect both Saccharomyces and other Flor veil-forming genera and suggest the possible consequences they can have on the processes of formation of the Flor veil of typical D.O. Jerez-Xèrés-Sherry wines. Results obtained show that different Flor veil yeast strains isolated in Fino wines and in Amontillados presented a great resistance to ethanol and all of them presented infection by Totiviruses. These were identified after the extraction of double-stranded RNA and amplified by multiplex PCR with specific primers for the most common viruses involved in the killer factor. Subsequently, the same strains of both the S. cerevisiae species and Wickerhamomyces anomalus were subjected to an antiviral treatment with ribavirin. After microbiological analysis with Methylene Blue (MB) plates and by rt-PCR, it was determined that most of them did not show killer factor and the viruses involved in it had been correctly eliminated under the treatment with ribavirin. Subsequently, competition and implantation experiments of the treated and untreated yeasts were carried out against their controls. The wines inoculated with yeasts infected by Totiviruses showed to be dominant in all cases.
Methodological issues of grape and wine water evaluation by quantitative nuclear magnetic resonance deuterium spectroscopy (2H(D)-qNMR)

Published: December 2023

The new methodological approach of rapid evaluation of intracellular grape and wine water without sample preparation, based on the quantitative nuclear magnetic deuterium spectroscopy (2H(D)-qNMR) is suggested and developed under the research program carried out under the scientific grant of the International Organization of Vine and Wine (O.I.V.). The approach provides a quantitative high precision measurement of the deuterium content in water based on the direct dependence of the areas of NMR signals on the number of nuclei responsible for these signals. The developed approach uses similar to the well-known SNIF-NMR method with an internal reference substance (IRS) - dimethyl sulfoxide (DMSO). The IRS signals in the NMR spectrum do not overlap with the signals of main components of the analyte (e.g., grape must/juice, wine). In addition, it is possible to change the deuterium content using an available NMR solvent - DMSO-d6. At the same time, the amount of deuterium in the IRS-DMSO is increased by adding DMSO-d6 so that the proportion of the standard, equal to 10-15% by volume, gives a signal commensurate in its intensity with the signal of water contained in the analyte. The exact amount of deuterium in the IRS is determined by comparing the integral intensities of signals in the 2H(D)-NMR spectrum in a standard water sample (VSMOW) with a known deuterium content. After calibration of the deuterium content in IRS, the analyte and DMSO in quantities of 0.5 and 0.075 ml, respectively, are placed in a standard tube, then the 2H(D)-NMR spectrum is measured in the following conditions: 90° pulse, 2.5 sec acquisition time, 3 sec delay relaxation, 1000 scans. Additionally, to assess the amount of water in the analyte, the 1H-NMR spectrum is recorded, from which the contents of main sample components, for example, ethanol, glycerol, sugars, etc., are determined. The calculation of the deuterium content is carried out by quantifying the integral intensities of the IRS signals and the water contained in the sample. The developed methodological approach has been validated in experimental tests to study the natural content of deuterium in intracellular water of grapes of different seasons, as well as to study changes in the quantitative balance of deuterium in the case of adding extension water to musts before and after fermentation.
Application of ultra-high pressure homogenization (UHPH) at different stages of wine production
Authors: Puig-Pujol Anna , Roca-Domènech Gemma , Quevedo Joan-Miquel , Trujillo Antonio-José
Published: December 2023

Ultra-High Pressure Homogenization (UHPH) is an emerging, efficient and fast technology that can be applied at different stages in winemaking in order to reduce or avoid the use of sulphites or other antimicrobial and antioxidant treatments. During 2022 vintage, four batches of must of three different white cultivars (Vitis vinifera L.) were processed by UHPH at 300 MPa with an inlet temperature (Ti) of 4 ºC and their effectiveness was compared with control batches (without SO2 addition) and musts that were sulphited with 60 mg/L of total SO2. A complete inactivation of yeasts and bacteria was achieved when grape juices were processed by UHPH, reaching up to 7 log of reduction in yeasts, 4.6 log for acetic acid bacteria and 4.3 log for lactic acid bacteria. All UHPH musts remained stable from a microbiological point of view for more than 8 months stored at 4 ºC in aseptic containers. Results showed that when antioxidant activity, colour intensity and total phenol index were measured, UHPH can be considered a protective technique, with a similar action to that of adding SO2. Furthermore, PPO enzymatic activity was completely inactivated in UHPH and sulphited musts. When a red wine contaminated by Brettanomyces was treated by UHPH at 300 MPa and Ti = 17 ºC, a 6.6 log reduction was obtained for this spoilage microorganism and no increase of volatile phenols were detected after 2 months.

Published: December 2023

Proper waste management has been emergent attention in varied human habitats. Following the best practices for waste management is essential for a sustainable living environment. This research work proposes a technology-supported self-sustainable aquaponics environment that automatically manages and controls the system by integrating with IoT technology and Naive Bayes algorithm for automated fish feeding. Water quality is monitored with sensors such as pH, temperature, humidity, dissolved oxygen, and water level sensors. Solid waste of fish is filtered and the nitrification process has been carried out by bio-filter. The water level of the fish tank is monitored and maintained by an auto system. Fish feeding requirements have been attained using ML model. The nutrient film technique-based planting system optimally extracts nutrients. The Vertical farming technique helps to reduce the land and water used for cultivation. The sensors are operated on microcontrollers namely Arduino UNO and Raspberry Pi. The sensed values are communicated through a mobile application for constantly monitoring the aquaponics environment. The prospect shows the self-sustainable smart aquaponic platform for farmers to grow fish and plants in a single system simultaneously to get increased production with fewer natural resources such as land and water.

Published: December 2023

Road networks play a essential role in transportation systems at the national, state, and local scenario. Ongoing efforts involve construction of new roads and the enhancement of existing ones to improve the overall efficiency of the transportation system. However, highway construction often results in environmental degradation. A more eco-friendly alternative known as CLSM relies significantly on industrial waste in its production process. CLSM, also known as flowable fill, is a self-compacted cementitious material that exhibits properties between concrete and soil. This paper focuses on evaluating the suitability of CLSM mixes in pavement layers and is prepared by combining ground granulated blast furnace slag, cement, and fine aggregates such as crumb rubber and copper slag sand. Flowability and marsh cone tests were conducted to assess the workability of the mixes. California Bearing Ratio (CBR) test, Unconfined Compressive Strength (UCS) to determine the mechanical properties of hardened CLSM. CBR values obtained for CLSM mixes (UCS range 0.28 – 2.42 MPa) was observed to be more than that of conventional pavement subgrade materials. Adoption of such CLSM mixes for pavement subgrade will lead to sustainable road construction.
Influence of Pulverized Cow Bone as Partial Replacement of Cement and Demolished Concrete as Full Fine Aggregates on Properties of Foam Concrete
Authors: Daarol Michelle , Ariola Christian Jan , Gerbania Lear , Napitan Krizer Wrey Yella
Published: December 2023

Cement is partially replaced by cow bone powder, and demolished concrete is used as fine aggregates in manufacturing foam concrete. Cow bone powder is a waste product with a high calcium content that may be used as a partial substitute for cement, and fine demolished concrete particles may be used to act as fine aggregates in foam concrete. Cow Bone powder is replaced in cement at 18%, 20%, and 25%. The study aims to determine the performance of the cow bone powder and demolished concrete mixture foam concrete compared to conventional foam concrete in terms of compressive strength, air voids, and fire resistance test. Comparing foam concrete with cow bone to ordinary foam concrete, the compressive strength of the foam rose at 18% and 20% replacement. However, foam concrete’s compressive strength dropped at 25% replacement of cow bone powder. The results show that cow bone powder significantly affects the foam concrete’s compressive strength. Additionally, since destroyed concrete wastes and a tiny amount of cow bone is fully utilized, the samples can receive more air, making this material perfect for lightweight partitioning. Pulverized Cow Bone as a partial replacement of cement and Demolished Concrete Waste does not influence the fire resistance of the samples.

Hydrodynamic pressure of water on the head face of an earth dam during an earthquake
Authors: Bestuzheva Alexandra , Gotsiridze George
Published: December 2023

The loads acting on the pressure face of hydraulic structures from the water mass of the reservoir during earthquakes are usually set in the form of a diagram of the coefficients of the added mass of water, while the hydrodynamic pressure of water along the height of the pressure face is distributed in proportion to the diagram of the obtained coefficients. The paper presents a solution to the problem of hydrodynamic water pressure on the pressure face of an earth dam at slope angles from 0 to 75 degrees (with respect to the vertical). Construction of isolines of the streamline function distributionψ (x, z) in the computational domain was carried out in PC MATLAB. Solution Δψ = 0 allows to build isolines of the distribution of the hydrodynamic pressure function φ(x, z) in the computational area. The paper presents hydrodynamic grids and graphs that make it possible to construct a diagram of the added mass of water for the entire range of emplacement of the upper slopes of dams. The developed method for solving the problem of hydrodynamic water pressure on the pressure face of the dam can be applied to any shape of the slope profile of the dam.

Published: December 2023

Construction projects in Iraq suffer from weakness in several respects, starting from feasibility studies and planning until the end of construction lifespan. Therefore, a study was required to demonstrate the importance of using artificial intelligence in the construction of infrastructure projects and sustainable development to reduce costs, errors, time, and to conserve energy and natural resources as much as possible. The benefits of artificial intelligence in the construction industry have been explained through the stages of the project that have been carefully selected, which represent the stages from the beginning to the end of the life of the project according to what is defined and customary in the construction of infrastructure projects and sustainable development projects in Iraq. A questionnaire was organized for experts specializing in construction industry who have sufficient experience to indicate their opinion on the importance of using artificial intelligence at all stages of the project in Iraq, and the results showed that there is a clear discrepancy in this importance, sequentially from the great importance in design and planning and ending at the stage of supervision and implementation, which experts seem to have preferred, that this paragraph needs to be kept under human management and follow-up.
Dry containment
Authors: Pergamenschik Boris
Published: December 2023

The dry containment (DC) is a metal cylindrical vessel (tank) 0.6 m thick, 5 m high, which is filled with serpentine concrete and surrounds the reactor vessel. DC reduces the radiation flux to the conventional concrete of the biological shield of the PWR reactor. Generates, due to the high content of hydrogen atoms in serpentine rock, a radiation spectrum with an increased content of thermal neutrons, which is important for the operation of the ionization chambers of the reactor power control system. Traditionally, the DC is dried after concreting the metal structure at a temperature of up to 2500 °C to remove water from the concrete that is not chemically bound during the hardening process. The drying operation is not fixed by the standard instruction, it is solved according to various schemes and is associated with a long preparatory period, significant labor and financial costs. There is no evidence of the need for drying. In the present paper, based on the analysis of the DC solution, a number of projects of works on its construction, existing instructions, the conclusion is made about the possibility and expediency of refusal from drying of DC and accompanying operations on quality control with the use of radioisotope sources. The corresponding cost savings are estimated at more than 100 million rubles for the power unit.

Published: December 2023

The method of injection fixing of subsiding soils in the foundations of buildings and structures is widely used in many countries of the world, including Mongolia. This article presents the results of experimental studies on the injection strengthening of loess-like sandy loamy subsidence soil on the territory of the city of Darkhan Monolia. Experiments to determine the physical and mechanical parameters, the mineralogical composition of the fixed subsidence soil were carried out according to the standard method in laboratory and field conditions. For injection fixation of subsiding soils, 20%, 30% and 40% solutions of liquid glass with a density of 1.19 g/cm3 were used, as well as a cement mortar prepared at a ratio of 1:20, 1:30 and 1:40 from Portland cement grade 450 The modulus of deformation of the fixed soil is 7.92...14.1 MPa, the compressive strength of the soil fixed with a solution of liquid glass is 39.0 kPa, and with a cement solution of 1:40, it is 137.0 kPa. Based on the results of experimental and theoretical studies, an effective method for fixing subsiding soil, taking into account environmental considerations and the regional characteristics of the territory of Mongolia, is injection grouting using a cement slurry prepared with a composition of 1:40 and grade 450.

Price management in construction investment in Vietnam: Current situation and proposed solutions
Authors: Nghiem Van Dinh , Thi Tuyet Dung Nguyen
Published: December 2023

The Covid-19 pandamic has caused unprecedented challenges and unpredictable fluctuations in Vietnamese economy. Production and supply chain of materials is constantly broken, while prices of energy, supplies, and raw materials have sharply increased, which has boosted construction costs and affected the medium-term public investment capital allocation plan. The regulation system on construction prices as a cost management tool has revealed inadequacies and no longer appropriate for investment projects using state capital or large-scale PPP projects, therefore no longer ensures the principles of accuracy and sufficiency. For construction investment to be effective and investment objectives to be met, it is necessary to complete the basis for the state management of costs, including the construction price system. This study examines the process of formation and management of construction prices in a number of developed economies such as the US., Germany, Poland, and Russia, analyzes and evaluates the shortcomings, and proposes solutions to improve construction price management in Vietnam.
Evaluating Different Machine Learning Models for Runoff Modelling
Authors: Slieman Alaa Ali , Kozlov Dmitry V.
Published: December 2023

Estimation and forecasting of hydrological factors are of particular importance in hydrological modelling, and surface runoff is one of the most important of these factors. Machine learning (ML) models have attracted the attention of researchers in this field. So, this article aims to evaluate several types of ML models such as autoregressive integrated moving average (ARIMA), feed forward back propagation artificial neural network (FFBP-ANN), and adaptive neuro-fuzzy inference system (ANFIS) models in order to estimate runoff values at Al-Jawadiya meteostation in the Orontes River basin in Syria. A large number of ARIMA models were built and the seasonal effect on the models also verified. After that, FFBP-ANN models were used with the change in the number of inputs, the number of hidden layers, and the number of neurons in the hidden layer. Also, a large number of FIS models have been built and artificial neural algorithms have been used in the process of model parameters optimization. The results showed a preference for artificial intelligence models in general over ARIMA models, as well as a slight preference for FFBP-ANN models over ANFIS models. This study recommends expanding the use of ML models to reach the best models for forecasting hydrological factors.

Published: December 2023

The article presents the results of the study of negative factors that accompany the process of building demolition and reduce the environmental safety of urban environment. Based on the system analysis of scientific research, the graph of the impact of negative factors on humans and the environment was compiled. The relevance of the study is justified by the need to ensure environmental safety in the production of demolition works. The purpose of the study was to identify the dependence of the level of negative impact on the characteristics of technological equipment and to improve the system of selecting protective measures, taking into account the requirements of legislation in the field of environmental safety. The result of the research is the developed conceptual model of decision-making on the choice and justification of the method of ensuring environmental safety during the liquidation of buildings in the conditions of dense construction on the basis of reducing the level of influence of negative factors. Practical application of the obtained results is possible in the design of building demolition as an additional justification for selecting the number and type of technological equipment, as well as an addition to the quality control system of works.

Authors: Bykov Nikolay Y. , Gorbachev Yuriy E. , Fyodorov Stanislav A.
Published: December 2023

The results of a numerical study of a supersonic underexpanded jet flowing from a conical nozzle into a rarefied environment are presented. The modeling was performed by the direct simulation Monte Carlo method. The range of parameters corresponding to the expansion ratio 40 < n < 240, the hydrodynamic regime of the flow in the nozzle and the rarefied regime of interaction of the jet with the environment, characterized by Knudsen numbers in the range 0.03 < KnL < 0.2, is considered. It is shown that in the specified range of KnL a drastic rearrangement of the flow structure occurs. For the lower limit of the KnL range, a shock-wave structure typical of a highly underexpanded jet is observed. For Kn = 0.2, it completely degrades. Data have been obtained on the process of dimer formation in an expanding jet. An increase in the mole fraction of dimers with increasing distance from the nozzle throat is shown both in the conical nozzle and in the initial section of the jet expansion region.

Authors: Salnikov Mikhail , Fedoseev Alexander , Sukhinin Gennady
Published: December 2023

In the current paper a numerical study of the forces acting of a one-dimensional chain of three dust particles levitating in the near-electrode layer of a gas discharge plasma is presented. In the described model dust particle motion is calculated in consideration of the action of gravity, external electric field, the Coulomb repulsion and the force induced by plasma space charge. The dependences of the dust particles charges and their position in space on the mean value of external electric field were calculated. The investigation showed the effect of discharging dust particles in the chain due to ion focusing. The spatial distribution of forces acting on the dust particle chain has been studied. It is noted that the Coulomb repulsion force relative to the center of the chain loses its symmetry with an increase in the mean electrostatic field. It is shown that the displacement of a chain of dust particles is determined by the force induced by the plasma space charge.
