The issues of processing bulk materials are of great importance in the energy, pharmacology, and chemical industries. New technologies have new requirements for the granulometric characteristics of individual components of powders and their mixtures. Often, the components of a mixture differ in their properties and grain sizes, thus, multi-stage processing of these mixtures is required to obtain powders with desired technological properties. Optimal control of the structure and operating modes of complex multi-stage apparatus to obtain powders with desired properties is a topical task. Methods of probability theory and fractional mass balance equations are used to model multistage gravitational classifiers. Mathematical programming methods are applied to solve optimization problems of powder classification. A generalized method of combinatorial matrix description of an open stage of regular multiproduct classifying elements for an arbitrary number of finished products is proposed. The proposed model of the considered stage is used for the matrix description of a closed system of devices with an arbitrary flow structure. The authors have determined the best structures and operating modes of individual stages to obtain powders with specified technological properties. The developed approach makes it possible to optimally control the structure of the cascade of classifiers and the modes of operation of its individual stages to obtain powders with desired technological properties, as well as to design systems for predictive diagnostics of the state of these installations in the energy, pharmacological and chemical industries.

Power equipment deterioration occurs during operation, it causes loss in reliability and efficiency, unscheduled shutdowns, and accidents. Now predictive analytics is one of the promising directions in the field of power engineering which allows to control and analyze the technical condition of power equipment. The problems of localization of deviation of technological parameters and detection of anomaly in the operation of power equipment are consistently solved in the framework of predictive analytics. The problems of deviations localization and anomalies detection are solved by the methods of statistical modeling and the classification algorithms respectively. However, for steam turbines the localization of deviation and the detection of anomalies having slow-flowing character are a difficult problem. Therefore, the issue of development of a method for continuous monitoring of technical condition and maintenance diagnostics based on a mathematical model of the steam turbine section flow characteristics is worth noticing. The method allows us to consider the effect of changes in the open flow area of the individual sections of a steam turbine on the pressure distribution over the steam flow path. The model of a steam turbine has been developed within the matrix formalization methodology. The solution of the system of linear and nonlinear equations is carried out by methods of computational mathematics. The solution of the optimization problems of the steam flow path diagnostics is carried out by methods of mathematical programming. A mathematical model of the cogeneration steam turbine Т-250/305-23.5-DB and a method for continuous condition monitoring and maintenance diagnostics of steam turbine have been developed. It allows us to localize deviation and detect anomaly by recovery of the open flow area of the individual sections of a steam turbine based on the pressure distribution over the steam flow path. The results of the statistical analysis prove that a mathematical model of the cogeneration steam turbine Т-250/305-23.5-DB has been recognized adequate. The method for continuous condition monitoring and maintenance diagnostics of steam turbine has demonstrated consistency of the obtained results and ability to solve diagnostic problems in practice. The developed model and method can be used as a module in the development of a software package for predictive analytics of power equipment.

Authors:   Ivanovo State Power Engineering University, Nechaev V.A. , Kosyakov S.V. ,   Ivanovo State Power Engineering University
Published: August 2023

Currently, when developing automatic speech recognition models for specialized subject areas, in particular for energy facilities, deep neural network architectures are used, which require a large amount of training data. At the same time, models often turn out to be poorly suitable for use in specific information systems due to poor-quality recognition of highly specialized subject vocabulary. Additional training of models to improve their quality in a specific context of recognition encounters the difficulty to obtain a sufficient amount of data and the laboriousness of their markup. Thus, an urgent task is to create methods that allow reducing the complexity of developing applied speech recognition models and improving their quality when used in subject areas, in particular, in the field of energy. Methods of thematic text modeling based on language models for adapting open data are applied. A deep neural network is used as a pretrained speech recognition model. For training, open-source datasets are used. A method to develop automatic speech recognition models for specialized subject areas has been developed. It includes the stage of intermediate learning of subject area vocabulary based on open-source data selected using thematic sampling. Based on the method, the authors have developed and studied a model of automatic speech recognition for energy facilities. It has showed higher recognition results than models obtained by traditional methods. Approbation of the proposed method has confirmed its effectiveness. The applied neural network model developed on the method has demonstrated the possibility to work in the information systems of energy facilities in Russian and English without additional training on proprietary data.
Sedimentary P- and S-Wave Velocity Structures in Shimousa Region of Kanto Basin Determined from Joint Autocorrelation and Receiver Function Analysis
Authors: Chimoto Kosuke
Published: August 2023

To determine the P- and S-wave velocities (VP and VS, respectively) of the sedimentary layers in the Shimousa region of the Kanto basin, Japan, the autocorrelations of P and S waves and the receiver function (RF) for the local earthquakes at the strong-motion stations in the region were jointly analyzed. Because the autocorrelations and RF were insensitive to the event location, the stacked functions for various events captured clear P and S reflections and the Ps phase at the bedrock of the basin. The PpPs phase was also clearly observed at some stations in the region. The arrival times of the P and S reflections and the Ps phase depended on the station. These phases arrived earlier at the northern and eastern parts of the region, and later at the southern and western parts. This trend shows good agreement with that expected from the 3D velocity structure model developed by the Japan Seismic Hazard Information Station. The VP, VS, and thickness (H) values were then estimated from the histogram of the H–V stack for the P and S autocorrelations and the Ps and PpPs phases in the RF. VP, which is less sensitive than VS and H, was not always well determined at some stations, whereas VS and H were well estimated with high resolution. It was found that the resolution depends on the station location in the region. This dependence could be caused by the appearance of clear phases in the functions.

Published: August 2023

Abstract

The punk community is one that is frequently encountered on the streets. Punks, as members of this community, have distinct and uniform appearances, such as wearing all-black clothing and a variety of body decorations. The presence of these punk kids is frequently regarded as upsetting by the larger population. Punk kids' behavior almost seldom results in aggression. The majority of this community's members are teenagers. The researchers want to know what causes or encourages punk kids to act aggressively. The literature review method was used in this study by analyzing various articles, journals, and books obtained through the Google Scholar search system. The results of this study indicate that punk children's aggressive behavior tends to be caused by a living environment that has less support for their development. Environments with high levels of poverty also influence this aggressive behavior. The aggressiveness shown tends to be active physical aggressiveness that is carried out directly.

Abstract: Adolescence is the period between childhood and adulthood when significant changes occur in cognitive, physical, and emotional elements. During this time, there is a rise in interest in sexuality. Unfortunately, youngsters' sexual curiosity is not accompanied by adequate sex education. Most individuals still consider discussing sexuality to be taboo. Finally, teenagers tend to learn on their own, either by talking with friends or searching the internet. The ease with which adolescents can have access to the internet is one of the contributing elements that can lead to their becoming addicted to pornography.The amount of pornographic material available, as well as adverts including sexual content, remain visible on the device's screen. Using the literature study technique, this study attempts to investigate the causes and consequences of pornography addiction in adolescents. Pornography addiction in adolescents is induced by both internal and environmental influences, according to the findings. Curiosity, spirituality, and emotional factors are examples of internal factors. Pornography addiction in adolescents can impair cognitive, emotional, and social elements, as well as possibly unsafe sexual behavior, due to external causes such as easy access to pornographic material on the internet, peers, and a lack of sexual education.

Abstrak: Memasuki masa remaja,  terjadi perubahan signifikan terjadi pada elemen kognitif, fisik, dan emosional. Pada masa ini, terjadi peningkatan minat terhadap seksualitas. Sayangnya, keingintahuan seksual remaja tidak dibarengi dengan pendidikan seks yang memadai. Sebagian besar individu masih menganggap bahwa membicarakan seksualitas adalah hal yang tabu. Akhirnya, remaja cenderung belajar sendiri, baik dengan berbincang dengan teman atau mencari di internet. Salah satu faktor yang berkontribusi terhadap kecanduan pornografi pada anak-anak adalah kemudahan mereka mengakses internet. Banyaknya materi pornografi yang tersedia, serta iklan yang memuat konten seksual, tetap terlihat di layar gawai. Dengan menggunakan teknik studi literatur, penelitian ini mencoba untuk menyelidiki penyebab dan konsekuensi dari kecanduan pornografi pada remaja. Kecanduan pornografi pada remaja disebabkan oleh pengaruh internal dan lingkungan, menurut temuan. Keingintahuan, spiritualitas, dan faktor emosional adalah contoh faktor internal. Kecanduan pornografi pada remaja dapat merusak elemen kognitif, emosional, dan sosial, serta kemungkinan perilaku seksual yang tidak aman, karena penyebab eksternal seperti akses mudah ke materi pornografi di internet, teman sebaya, dan kurangnya pendidikan seksual.

Published: August 2023

The study's objective was to ascertain the prevalence and defining characteristics of anemia in coronary artery disease patients. Retrospectively, 534 patients with comorbid anemia and coronary artery disease were examined. All patients were determined to have ongoing coronary supply route infection. The normal time of examined patients was 76.2 ± 5.11. Males with hemoglobin levels below 13.5 mg/dL and females with hemoglobin levels below 11.5 mg/dL were diagnosed with comorbid anemia. The patients were randomized by sex, age, and type of coronary corridor infection. Among all analyzed patients with coronary vein sickness frailty is viewed as in almost 75% of cases, which matches with the writing information. In individuals after 50 pallor is more normal in men than in ladies, while in youthful and moderately aged patients weak condition is more run of the mill in females. Just in under 90 case reports the determination of frailty was kept in the last clinical analysis during patients' release from the emergency clinic, in one more case low hemoglobin level was not thought about by doctors. Roughly only 35% of all instances of serious paleness were not analyzed in a medical clinic and no fitting rectification of hemoglobin level was performed. The rate of sickliness doesn't rely upon the type of constant coronary vein infection. In many patients with coronary course sickness comorbid sickliness is of normochromic and normocytic character. Alongside movement of the seriousness of the comorbid paleness, a genuinely critical increment of the hospitalization time frame is noticed. In patients with coronary corridor sickness and comorbid pallor, the recurrence of hospitalizations each year is additionally expanded alongside iron deficiency level of seriousness. In conclusion, constant types of coronary corridor sickness in old and feeble patients in 69.89% of cases are confounded by comorbid paleness of various levels of seriousness. In more established patients with coronary course sickness, the weak disorder is most frequently brought about by respiratory illnesses, stomach ulcers, and duodenal ulcers, diseases of various limitations. In many patients with coronary conduit sickness comorbid sickliness is of normochromic and normocytic character.

Does regional trade integration reinforce or weaken capital mobility? New evidence from four free trade areas
Authors: Ganic Mehmed , Novalic Amila
Published: August 2023

The study aims to empirically determine whether a higher level of trade openness and the presence of better legal protection for investors enhances the impact of trade bloc membership on capital mobility based on four trading blocs: Eurasian Economic Union (EAEU), Central American and Dominican Republic Free Trade Agreement (CAFTA-DR), Central European Free Trade Agreement (CEFTA), and the Pacific Alliance. This study employs the fully modified and dynamic ordinary least squares estimators and a panel quantile regression cointegration estimator. The study finds that a country's affiliation with a trade bloc improves capital mobility in the whole group and EAEU region, low capital mobility in the Pacific Alliance region and moderate low capital mobility in the CAFTA-DR region. The legal protection system alone provided for the investors does not improve the level of capital mobility unless its interaction with investment is included. Also the study reveals that high trade openness does not necessarily lead to better capital mobility for the studied trade blocs.

The aim of the paper is to explore the factors impacting export intensity of SMEs in India. It examines the influence of various firm level variables on export intensity. The sample considered for the study includes 50 SME firms from different industries ranging from equipment and manufacturing to textile. Data for ten years (2011-2020) has been analyzed for drawing relevant results. For regression, Least Square Dummy Variable corrected (LSDVC) estimates have been used to address the issue of heteroskedasticity and autocorrelation issue present in the data. The results arrived at indicate  that the expenditure incurred on research and development, selling and distribution acts as an investment which provides returns in terms of better export performance. Also, top managers having international experience can be an important asset for a firm looking for expanding in international market. These results have substantial implications for the management of SME firms.

Evaluation of malignant breast masses with abbreviated breast magnetic resonance imaging
Authors: YILMAZ Ebru , GÜLDOĞAN Nilgün
Published: August 2023

Objectives: Our study aimed to investigate the sensitivity of the abbreviated magnetic resonance imaging (MRI) in the detection of tumors in breast cancer patients.
Methods: Patients who underwent breast MRI between March 2018 and October 2021 were reviewed retrospectively. Patients with a histologic diagnosis of breast malignancy were included in the study. Patients who underwent a biopsy or an interventional procedure before the MRI examination and who received neoadjuvant chemotherapy were excluded from the study. Abbreviated MR protocol included a pre-contrast T1-weighted, 1st minute contrast-enhanced T1-weighted, and 1st minute subtracted series. Additionally, 2nd minute post-contrast series were evaluated.
Results: A total of 83 lesions with a histologic diagnosis of breast cancer were evaluated in 81 patients. The mean age of the patients included in the study was 51.08 years (range: 27-79 years). Seventy-four of the 83 breast lesions showed contrast enhancement in the 1st minute contrast-enhanced images and subtraction images (sensitivity 89.1%). When missed cases were re-evaluated all of them were visible in the second-minute contrast-enhanced series.
Conclusions: In this study, malignant lesions could be detected with high-sensitivity abbreviated MRI protocol and the addition of second-minute contrast-enhanced series to the protocol significantly improve lesion detection. We believe that MRI with the abbreviated MRI protocol can be used for screening purposes in high-risk women with dense breasts.
Effects of embryo characteristics in frozen-thawed single euploid blastocyst transfers on pregnancy outcomes: a retrospective cohort study
Authors: ÖZER Gönül , ÖZKARA Gülçin
Published: August 2023

Objectives: Our study examined the effects of the trophectoderm biopsy (TB) day and the presence of necrotic foci (NF) or separate blastomeres (SB) within euploid embryos on in vitro fertilization (IVF) pregnancy outcomes.
Methods: This retrospective cohort study was conducted from January 2017 to September 2021 at Memorial Sisli Hospital, Istanbul, Turkey. The study comprised a total of 2758 frozen-thawed euploid embryo transfer cycles. After thawing, blastocysts were graded using Gardner's classification Top-Quality (TQ), Good-Quality (GQ), Moderate-Quality (MQ), Poor-Quality (PQ) and further divided into groups according to the presence of NF and/or SB and evaluated for pregnancy outcomes.
Results: There were significant correlations between pregnancy outcomes and the degree of blastocoele expansion, as well as the presence of NF or SB in the euploid embryo. Ongoing pregnancy rates were lower in the group with NF in the inner cell mass (ICM) or trophectoderm (TE) than in the group without NF. The presence of SB decreased the rates of ongoing pregnancy and increased the rates of miscarriage. Embryos with expansion grades ≤ 3 had lower rates of ongoing pregnancy and higher rates of miscarriage compared to embryos with expansion grades> 3. TQ and GQ embryos had a higher rate of ongoing pregnancy and a lower rate of miscarriage than MQ and PQ embryos.
Conclusions: When selecting the embryo to be transferred to a patient, careful consideration should be given to the morphological grade of the embryo as well as whether or not it contains NF and SB.

Authors: Janus Edyta
Published: August 2023

Wybuch pandemii w znaczący sposób wpłynął na rzeczywistość społeczną, której obecna charakterystyka odnosi się przede wszystkim do nieprzewidywalności, permanentnej zmiany i trudności w określeniu działań pozwalających poradzić sobie z konsekwencjami występujących zagrożeń, zarówno na poziomie makro, jak i mikro.

Sytuacja ta w sposób szczególny dotyka grup, które jeszcze przed wybuchem pandemii potrzebowały wsparcia. Jedną z nich stanowią opiekunowie domowi osób cierpiących na demencję.

Celem artykułu jest przedstawienie sytuacji opiekunów domowych, związanej ze świadczeniem opieki na rzecz ich bliskich chorujących na demencję w kontekście pandemii. Opis dokonywany jest na podstawie danych pozyskanych w wywiadach swobodnych pogłębionych, zrealizowanych w 2021 roku na próbie dobranej w sposób celowy. Badani uznali, że pandemia w zdecydowany sposób wpłynęła na ich funkcjonowanie, w szczególności na sprawowanie opieki (poczucie większego obciążenia ze względu na ograniczenie wsparcia instytucjonalnego i dostępności do podmiotów medycznych), konieczność odnalezienia się w rzeczywistości wirtualnej, wzrost poczucia wykluczenia oraz pogorszenie nastroju wynikające zarówno z doświadczeń osobistych, jak i obserwacji stanu osoby pozostającej pod ich opieką.

The relevance. Tire recycling contributes to the environmental situation due to the cost-effective disposal of large volumes of tires out of service, in addition, it is an opportunity to obtain valuable chemical products without using natural resources as the main sources of initial reagents. The main aim of the research is to identify and propose directions for processing car tires and the solid residue of their pyrolysis, depending on their type and quality. Objects: automobile tires of domestic and foreign production; pyrolysis products and their subsequent refinement of various car tires. Methods: technical analysis of solid carbon-containing materials – Eschka method, iodometry for determining the iodine number, determination of moisture and pH of an aqueous suspension, ash content, volatile matter, light transmission coefficient of a toluene extract. Results. It was revealed that the solid pyrolysis residue studied in the work with the obtained indicators of its quality can be used as a filler in the rubber mixture or as a sorbent for heavy oil products, and a scheme was developed that reflects the ways of processing the solid pyrolysis residue obtained as a result of the disposal of passenger cars. and truck tires of various domestic and foreign manufacturers. The result of the work, in particular, the dependence of the direction of processing the solid residue of the pyrolysis of car tires from various manufacturers on its quality indicators, can serve as a theoretical basis for developing a unified program for recycling car tires in order to preserve and improve the environmental situation in various regions.

The relevance of the research is caused by the need to involve fields with high viscosity oil in the development, since fields with low and medium viscosity oil are depleted. Oil viscosity directly depends on the temperature, therefore, thermal enhanced oil recovery methods are used to reduce the viscosity. From the point of view of using the heat injected into the formation, the most effective thermal method is the cyclic steam stimulation, i. e. cyclic steam injection into the well. However, when steam moves through the pipe, it condenses, that is why the production at the well bottom-hole are often has high water cut. Accurate calculation of the heat carrier parameters along the entire wellbore will help to avoid this problem. The main aim of the research is to determine the effect of the well inclination angle, steam quality at the wellhead, initial pressure and thermal conductivity of thermal insulation on the heat carrier characteristics in the wellbore, considering flow modes. Objects of the research are deposits with high-viscosity oil. Methods: physical and mathematical modeling of injection of a two-phase (steam-water) heat carrier into the reservoir based on the laws of conservation of mass, momentum and energy, considering the movement of the heat carrier along the wellbore of a directional well, heat loss through the walls of the well and fluid flow modes. Results. The calculation of the steam quality and heat carrier flow rate along the wellbore of a directional well was conducted. The influence of the well inclination angle on the parameters of the heat carrier at the well bottom-hole (steam quality, pressure and wellhead flow rate of the heat carrier) is analyzed. It is determined that the smaller the well inclination angle, the deeper the steam penetrates through the depth of the formation.

The relevance of the work is caused by the existing imperfection of organizational, technical and information security of the state cadastral valuation in the Russian Federation in the context of digital transformation in the field of land and property relations. This state is determined by the departmental disunity of state information resources. This is especially clearly illustrated in the agricultural land management system, which has negative impact on the reliability and quality of determining the cadastral value of such lands. The aim: to propose a conceptual solution for the development of the digital infrastructure of the cadastral assessment system and its information support. The methods: theoretical analysis of the study and generalization, as well as other generally accepted analytical methods. Results. Modern model of the organization of information interaction of departmental data sources on the state and use of agricultural land was formed. The resulting model allowed us to identify problems that complicate the effective information support of cadastral valuation of agricultural land. As an evidence base for the lack of complete and reliable information about agricultural lands, an analysis of reports on the state cadastral assessment of agricultural lands in a number of regions was carried out. The results of the analysis showed that in most cases appraisers do not use the price-forming factors provided by the current methodology, due to the lack of available and reliable information. As a result of the conducted research, a solution was developed for the development of the digital infrastructure of the cadastral assessment system. A technological scheme for collecting, processing and analyzing initial data on the values of price-forming factors is proposed, based on the introduction of the digital service «Cadastral Assessment», which provides spatial data about objects.

The relevance. The depletion of readily available hydrocarbon reserves determines development of fields with complex geological environment. Managed Pressure Drilling marked the era of high-precision well parameters monitoring during drilling. This technology has provided access to deposits that were previously considered practically «unusable». The main goal of using managed pressure drilling technology is to control downhole pressure within specified limits in order to prevent fluid loss, fracturing, as well as unwanted kick of reservoir fluids into the wellbore. However, if for a certain period of time there is a kick of reservoir fluid from an open borehole or there are losses of drilling fluid, then it is not possible to control the downhole pressure within the specified limits. In this case, it is necessary to use an additional method or algorithm that marks such periods and indicates to the operator or the monitoring system about the presence of kick or absorption of drilling mud. The problems described earlier predetermined the aim of this work. It is claimed that the intelligent system can automatically monitor and analyze parameter trends, detect anomalies in the change of drilling parameters in real time, predict in advance the probability of formation fluid kick and warn the drilling engineer at an early stage, which will allow implementing preventive activity to maintain the required downhole pressure profile. The main aim: create the kick detection machine learning model which predicts kick probability during the managed pressure well drilling using mud logging service data. Objects: multivariate-sensing time-series data of mud logging and measured pressure drilling service. Methods: analysis and evaluation of anomaly detection techniques of determining kick during managed pressure well drilling using machine learning. Results. The authors have performed the overview of anomaly detection techniques of determining kick during managed pressure well drilling using machine learning. Classical machine learning algorithms were tested with labeled test data in order to evaluate its performance. The authors have developed kick detection model with gradient boosting algorithm, evaluated its performance with labeled test dataset. Promising areas of further research were identified.
