Civilian Attitudes of Russian Students in the Context of a Special Military Operation
Authors: Smirnov V. A.
Published: September 2023

The article analyzes individual elements in the structure of civil attitudes of Russian students in the situation of the beginning and continuation of a special military operation (SVO). A special military operation acts as a kind of “litmus test”, which allows to identify the features of the civic consciousness of students, since it is in a crisis situation that latent value attitudes that determine social and civic behavior are actualized. The article is based on the results of an empirical sociological study. The study sample is quota– based, stratified by gender, the sample size is 1,380 people aged 18 to 22 years. As a result of the conducted research: the polarization of Russian students in terms of attitude to a special military operation is justified; the conclusion is made about the “background” nature of the SVO for a significant part of the student youth; the influence of ITS on the growth of stress among students faced with its results has been proven; the hypothesis about the influence of the SVO on the dynamics of civil attitudes of Russian students is confirmed. In particular, a special military operation has an impact on reducing students’ trust in socio-political institutions and actors, and also affects the dynamics of migration sentiments, increasing the percentage of young people considering migration as a possible option for a life trajectory. The study demonstrated the need for further study of the stability of the civic attitudes of Russian youth in the context of the escalation of “new” cognitive wars, as well as an analysis of the effectiveness of state institutions of socialization in a situation of geopolitical instability.
Semi-quantitative measurement of calcium carbonate in historic gypsum mortars, using diffuse reflectance infrared Fourier transform spectroscopy
Authors: Kochazekzaei Alireza , Mehrabad Mahsa Saidi , Ajorloo Bahram
Published: September 2023

This paper uses Fourier transform infrared spectroscopy to semi-quantitatively measure the amount of calcium carbonate in historical gypsum mortars. 17 historical mortar samples related to Arch of Alishāh in Tabriz-Iran, belonging to the Ilkhanid period, were evaluated. The methodology used in this study was diffuse reflectance infrared Fourier transform spectroscopy [DRIFTS]. Gypsum mortars containing 0-6.5% calcite were prepared and analysed using an FTIR spectrometer. The calibration curve was prepared based on the band intensity ratio of 1485 cm-1 related to carbonate vibrations in calcite to 660 cm-1 corresponding to sulphate vibrations in gypsum. Calculating the amount of carbonate in all historical mortars shows the presence of about 0.12 to 1.08% carbonate in gypsum mortar. According to obtained results, it can be acknowledged that due to the meagre amount of carbonate in the mixture of mortars, the existing carbonate has entered the mortar as an impurity through soil or dissolved salts. This can indicate that, contrary to the initial idea about some of these mortars, lime and gypsum mixture was not used as the main component in the making these mortars.
Concrete durability evaluation in new built pavement sections of expressways in Poland
Authors: Glinicki Michał
Published: September 2023

A review of concrete durability at several sections of the new built expressways in Poland is presented. Two-layers jointed plain concrete pavements were constructed using a slip-form technology. For freeze-thaw and deicing salts durability of concrete the specified air void properties, including the spacing factor and the microvoids content, was evaluated on core specimens drilled from the constructed pavements. The observed system of fine air voids indicates optimal features for increased frost and scaling resistance without a significant negative impact on strength. The correlation was established between the microvoid content in the hardened concrete and the data of the Super Air Metre on fresh concrete mix was established. Concrete durability in high moisture environment, combined with fatigue traffic load and external supply of alkaline deicing salt solutions, was considered using newly developed principles of nonreactive aggregate selection. The aggregate selection based on petrographic analysis and the assessment of expansive behaviour of concrete was fully confirmed using the performance tests with external supply of sodium chloride. The suitability of the established methodology for durability acceptance testing for exploration of alternative materials for paving is discussed.
Zero-point Energy Conundrum for Spin 1 Particles
Authors: Bevelacqua Joseph
Published: September 2023

The zero-point energy concept results in an infinite energy that has not yet been fully resolved. This paper reviews the zero-point energy for spin 1 particles utilizing the Proca equation. The need for the zero-point energy is confirmed in Santilli's synthesis of the neutron from the proton and the electron in the core of a star. 

     A possible resolution lies in establishing a cutoff energy (e.g., at the Planck scale) that negates the singularity. This singularity is avoided by establishing a restricted energy region that precludes exceeding the cutoff energy scale except under extreme circumstances (e.g., during a big bang/big crunch event). Potential energy functions, analogous to the Higgs potential or the short range hard core nuclear interaction, are introduced as possible mechanisms to establish the cutoff energy.
The Cost of Dodd-Frank Act for Commercial Banks
Authors: Cruz Darik , Feliberty Miguel Vicens
Published: September 2023

The intent of this article is to explain how the Dodd-Frank Act impacts banks and puts a spotlight on the cost of this Act to financial institutions, especially small banks. As part of the discussion, federal agencies are described as the regulators in charge of supervising strict compliance and adherence to the applicable law. Through our research it is apparent that part of the reporting costs is transferred to the consumers in different fees and charges, which impacts the bank’s competitiveness.  We depart from the premise that large banks could transfer these costs to consumers easier, because they have a critical mass of clients and products, enough to cover the additional expenses incurred when conforming with the regulation. Additionally, we analyze the cost of implementation from perspective of size which shows a substantial difference to institutions of various sizes. We conclude the paper recommending additional research and primary data collection that could contribute to a better understanding of the cost of the Dodd-Frank Act.
Rural-Urban Differences in Poverty: An Analysis of Pennsylvania Counties
Authors: Alcantara Angel , Brewer Stephanie M. , Jozefowicz James J.
Published: September 2023

This study examines the determinants of poverty in rural and urban Pennsylvania counties. Economic and demographic characteristics are evaluated in their relation to the poverty rate using panel data from 2000 to 2019 for the 67 Pennsylvania counties. A two-way fixed effects model is estimated to account for unobserved county-specific and time-specific heterogeneity. The results indicate that there are rural-urban differences in the impacts of explanatory variables. In rural Pennsylvania counties, economic factors have significant effects on the poverty rate. The percentage of employment in manufacturing and construction are negatively related to the poverty rate, while the percentage of renters and employment in agriculture are positively related. In contrast, only the percentage of female-headed households has a positive, statistically significant impact in urban counties. Oaxaca (1973) decomposition indicates that structural characteristics in rural counties help mitigate their poverty rates. The results suggest that different policies must be implemented in urban and rural counties to alleviate poverty.

Published: September 2023

Background: In several genetic epilepsies, the genotype-phenotype relationship is complex in which pathogenic variants in the same gene may causes different epilepsy phenotypes. As a typical example, pathogenic variants of KCNQ2 have been known to cause either self-limited familial (and non-familial) neonatal epilepsy or early-onset epileptic encephalopathies. In spite of very different prognosis in terms of both epilepsy and development, both usually present as neonatal seizures within the first week of life. Case presentation: The patient, who was born at term after an uneventful pregnancy, had onset of tonic seizures at 2 days of age. Family history was negative for seizures or epilepsies. During the early stage (from onset to 6 months of age), he exhibited some electroclinical features resembling epileptic encephalopathy, including marked abnormalities on electroencephalogram, poor response to epileptic medications, hypotonia, and mild motor developmental delay. However, his seizures remitted from 4 months of age. And at his last evaluation at 20 months old, he presented cognitive and motor development within the normal range. His outcome, therefore, is more consistent with self-limited neonatal epilepsy. Whole exome sequencing followed by Sanger sequencing confirmation revealed that the patient had a heterozygous mutation c.1030T>G (p.Trp344Gly) in KCNQ2 gene which has not been previously reported. Examination of this mutation in the parents implied that this mutation occurred de novo. This mutation was classified as ``likely pathogenic'' according to standards of The American College of Medical Genetics and Genomics. Conclusions: This study reported a rare case of self-limited non-familial neonatal epilepsy with a novel KCNQ2 gene mutation. It should be cautious that some patients with KCNQ2-self-limited non-familial neonatal epilepsy may present some features resembling epileptic encephalopathy at onset/early stage. The complex genotype–phenotype correlation of KCNQ2-related epilepsies and the genetic counselling involved with the case are also discussed in this case report.

Overview: Hepatocellular carcinoma is a complex disease and has a high mortality rate. Identifying biomarkers that can use to diagnose early and prognosis of HCC is essential to reduce the burden of HCC on patients, families, and society. Methods: The bioinformatics methods were used to study the expression of the SET nuclear proto-oncogene gene in cells, tissues, and the correlation of SET with hepatocellular carcinoma. The data from the open databases were used in this study include COMPARTMENTS, Kaplan-Meier Plotter, STRING, TIMER, UALCAN, The Cancer Genome Atlas database, and Gene Expression Omnibus. Results: At the cellular level, the expression level of the SET gene was highest in the nucleus, endoplasmic reticulum, cytosol. The SET gene's mRNA expression appeared in all body tissues. The TPM median of the SET gene in liver tissue was 33.42. The expression level of SET in hepatocellular carcinoma tissue was higher than that in non-cancer tissue for both males and females. The SET gene is an independent factor for the diagnosis and prognosis of HCC. Patients with high SET expression have a short survival time and a higher rate of recurrence than patients with low SET expression. The SET expression has a significant correlation with B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and especially dendritic cells in hepatocellular carcinoma. Conclusion: High expression level of SET related to a poor prognosis in patients with hepatocellular carcinoma. This study demonstrates that the SET is a potential biomarker for early diagnosis and prognosis of hepatocellular carcinoma.

Introduction The aim of this study was to investigate the relationship between leisure physical activity and high-risk behaviors with personality mediating role in students of University of Isfahan. Method The research method was descriptive-correlational and in terms of purpose was part of applied research that was conducted in the field. The statistical population of the study consisted of all students of University of Isfahan in the academic year 2020-2021(16,563 people) 375 people were selected as a sample by stratified sampling method using the Krejcie and Morgan’s table. A researcher-made checklist of leisure-time physical activity, high-risk behaviors, and personality questionnaires were used to collect data. The validity of the research tools and their reliability (by Cronbach's alpha test) were evaluated. Research data were collected in library and field sections. To analyze the research data, descriptive and inferential statistics was used. Finding The results showed that high-risk behaviors are less in the leisure time of active students. In addition, with increasing physical activity in leisure time, high-risk behaviors decrease. On the other hand, the more psychotic students are, the more high-risk behaviors are likely to happen. In addition, the separate relationships between leisure-time physical activity and personality with high-risk behaviors were significant. Discussion However, the results showed that when the personality variable was included in the relationship between leisure physical activity and high-risk behaviors, the relationship between the two variables became insignificant. Therefore, in order to reduce high-risk behaviors among students, it is better for university officials to increase the possibility of students participating in leisure-time physical activities by holding extracurricular sports classes and easy access to sports facilities.

Published: September 2023

The human body relies on controlled breathing to ensure oxygen reaches all cells while filtering out contaminants to protect the lungs. However, infections like the Delta virus and SARS-CoV2 (COVID-19) have led to Acute Respiratory Distress Syndrome (ARDS), requiring urgent medical care, including mechanical ventilation. The overwhelming number of patients has strained healthcare organizations and workers, necessitating advancements in automated healthcare technology. To address this challenge, we propose a novel solution to predict pressure in mechanical ventilation (MV) for various lung illnesses. The goal is to accurately predict the pressure within the respiratory circuit, which poses a challenging sequence prediction issue. To tackle this, we employ a cutting-edge deep learning approach known as Long Short-Term Memory (LSTM), which exhibits remarkable performance in selectively recalling patterns over time. While traditional recurrent neural networks (RNNs) can handle short-term patterns well, the introduced LSTM technique excels in managing complex sequence prediction problems. Comparing the proposed method with four existing algorithms, the researchers demonstrate that their approach achieves significantly higher accuracy. The impressively low error rate of 1.85 × 10−7 showcases a substantial improvement over existing system. This groundbreaking advancement has the potential to alleviate the pressure on the current healthcare infrastructure and significantly improve care for patients in need of mechanical ventilation due to respiratory issues.

The analysis method was carried out by determining the index value based on the Guidelines for road slope risk assessment (2018) and then analyzed to obtain the risk category. The results of 4 slopes obtained 2 slopes with high risk, 1 slope with medium risk, and 1 slope with low risk. In the risk assessment, the parameters of engineering buildings, geometry and geology of slopes play a major role in determining the risk category. Mitigation carried out on the 4 slopes is carried out in accordance with the risk category such as routine maintenance, rehabilitation, and slope instrumentation. The mitigation prioritization is done first on slope D then slope A, slope B, and slope C.
Optimization of Compliance and Mitigation of Accounting Frauds in American Organizations
Authors: Lima Alessandra Marques
Published: September 2023

It is through fraudulent accounting records that organizations’ annual results invariably lead directors and stakeholders to substantial losses, if not bankruptcy. The literature shows that financial frauds result from improper accounting entries, stemming from the bad intentions and greed of corrupt individuals in top management positions in various businesses. These individuals choose to engage in conduct that harms entire groups composed of companies, workers, and investors, affecting their credibility and integrity in their industry and also impacting professionals in the fields of accounting and auditing. In order to prevent financial frauds, organizations must take preventive measures by adopting good practices in Corporate Governance through the implementation of effective compliance actions, establishing specific and effective objectives among internal controls, and avoiding risks and accounting practices that may negatively impact the organizations. This original article, prepared through bibliographic research, aims to demonstrate that compliance actions contribute to the mitigation of fraud when properly applied in administrative and organizational processes. As a result, it was found that adopting compliance measures within the organizational system is not enough without regular verification of its effectiveness by administrators and managers.

ВОДОСПОЖИВАННЯ РОСЛИН ЯЧМЕНЮ ЯРОГО ЗАЛЕЖНО ВІД УДОБРЕННЯ ТА ПОПЕРЕДНИКА
Authors: Породько Максим Анатолійович
Published: September 2023

На основі проведених досліджень в період 2018-2020 рр. в умовах Правобережного Лісостепу України встановлено, що найменший коефіцієнт водоспоживання за вирощування ячменю був після попередника кукурудза на зерно. За даного попередника витрачання вологи рослинами ячменю ярого було найбільш економне – 375 м3/т насіння за технології вирощування, яка передбачала внесення добрив у дозі N45P90K90 + N45 (IV). Вирощування ячменю після попередника соя впливало на зростання водоспоживання до рівня 425 м3/т насіння, що на 50 м3/т насіння, або 13 % більше, ніж за вирощування після кукурудзи. В цілому, за рахунок внесення різних доз мінеральних добрив після попередника соя, за трьохрічний період досліджень, у роки з різним рівнем зволоження та гідротермічними показниками, як за осінньо-зимового накопичувального періоду, так і за вегетаційного весняно-літнього періоду, відмічали зменшення коефіцієнта водоспоживання на 33–301 м3/т, шо свідчить про ефективніше використання вологи рослинами ячменю на удобрених варіантах порівняно з контролем. Після попередника кукурудза на зерно спостерігається аналогічна залежність. Встановлено, що найвищу урожайність 4,88 т/га ячменю ярого сорту Віраж забезпечила технологія вирощування за внесення добрив в дозі N45P90K90 + N45(IV) на фоні інтегрованої системи захисту із застосуванням стимулятора росту після попередника кукурудза на зерно. За аналогічної технології вирощування після попередника соя отримали нижчий урожай на рівні 4,39 т/га. Проведений математичний аналіз водоспоживання ячменю ярого за різних попередників показав, що існує середній кореляційний зв'язок (r = 0,506) урожайності із загальним водоспоживанням за вирощування після сої, тісний зв'язок (r = 0,835) за вирощування після кукурудзи. Разом з цим, встановлено тісний обернений зв'язок урожайності з коефіцієнтом водоспоживання за обох попередників, про що засвідчують коефіцієнти кореляції, які становили: за вирощування після сої r = –0,993, за вирощування після кукурудзи r = –0,957. В цілому рівень водоспоживання залежав від системи удобрення та рівня забезпеченості вологою після попередника.

З'ясовано, що Сумщина може долучитися до дійсного вирішення проблеми енергозбереження та розвитку біоенергетики у рамках створення плантацій енергетичної верби Матсуда. У процесі дослідження вказано планування вирощування та ефективність застосовування енергетичної верби Матсуда для енергозабезпечення північно-східного Лісостепу України, доведено перспективу вирощування, перероблення та використання біоенергетичних культур у Сумській області. Для реалізації мети дослідження виконано такі завдання: проаналізовано наукові підходи при вивченні проблем енергозбереження та біоенергетики; розглянуто особливості природно-ресурсного потенціалу Сумщина; проведено можливі спостереження за розвитком і ростом верби Матсуда; досліджено реальні потреби і можливості вирощування у Сумській області енергетичної верби як біоенергетичної культури; У роботі розглянуто деякі технологічні заходи щодо вирощування контейнерного посадкового матеріалу S. matsudana: для створення лісоплантаційних насаджень. Доведено, що за умов кореневласного розмноження досліджуваного таксону необхідно заготовляти мікропагони до фази набрякання бруньок. Експериментальним шляхом було встановлено, що на відтворювальну здатність живцевого матеріалу не впливає його товщина. Доведено, що у міру збільшення товщини живця (0,6-1,5 см) спостерігалося збільшення маси садивного матеріалу. При використанні мікропагонів товщиною 0,6 см маса рослин становила 54,13 г, а в контролі – 191,12 г, що в 3,53 рази менше. У процесі дослідження було розглянуте питання щодо впливу об’єму горщика на масу кореневої системи, надземної частини та площу листкової поверхні посадкового матеріалу. За використання горщиків об’ємом 0,75 л площа листкової поверхні становила 2471,3 см2, що 23,1 % менше, ніж в контролі (1,2л). Було виявлено, що субстрат впливає на якісні показники садивного матеріалу досліджуваного таксону: найліпші біометричні показники отримані за умов використання високопоживного субстрату.

The work considers the problems of social engineering in modern messengers, and provides classification indicators for modern attacks. Attention is focused on the Telegram messenger, whose channel owners and visitors to these channels may suffer from the intervention of fraudsters who cannot always be identified in time. Fraudsters or malicious bots are exposed and removed as a result of certain user complaints, very often when the purpose of the malicious intervention has already been realized. This indicates the need to develop new proactive solutions. The purpose of this work is to enrich offensive security mechanisms for social messengers by using bots and artificial intelligence using specially created prompts. The novelty of the work. It is proposed to place a kind of honeypot analogues in the space of communication. The role of the decoy victim is given to a specially configured bot disguised as a user, capable of carrying out a conversation according to a given scenario. The bot’s algorithm has been developed. Methodology. Social engineering is seen as a proactive security tool aimed at identifying vulnerabilities that attackers can exploit, as well as a reverse defense by obtaining information from fraudsters that compromises them. Main results. The work successfully combined developed offensive security scenarios for real Ukrainian chats at the time of the research, with the capabilities of ChatGPT, which made it possible to implement a bot, with the ability to communicate according to the scenario specified by the security specialist. Testing of the bot and the corresponding application in the Telegram channel was carried out, with the consent of real users, which proved the workability of the solution. Conclusions. The modern level of artificial intelligence tools allows one to obtain valuable information about attackers in the information space, conduct automated security testing, and implement other offensive security scenarios. Channel administrators can use the solution as a channel subscribers filtering tool.
