Assessment of the Numerical Behavior of Remolded and Undisturbed Clayey Soil
Authors: Waheed Mohanned , Asmael Noor 
Published: December 2024

Abstract
The simulation of soil behavior using finite element analysis depends mainly on the input parameters considered in analysis, moreover, in the case of clayey soil, most of the experimental studies for small models are performed on remolded samples because of difficulty of providing undisturbed soils. This leads to unreal results for numerical analysis as the validation process of numerical results is performed on remolded sample.
It was conducted experimental work on remolded clay including load-settlement tests of model footing at three states on undrained cohesion (cu), and then performed unconfined compression tests at the same undrained cohesion. After that, performing numerical modeling of the model footing from the data of unconfined compression tests.
It was observed that the value of the modulus of elasticity in clay from unconfined test considering the initial tangent is low for remolded state compared to the findings of the previous research.
Moreover, great care must be taken in selecting the elasticity modulus in performing the numerical analysis of the clayey soil, however, for undisturbed clay it is greater than remolded, the difference in the value is up to two times for stiff clay in the case of large scale footing, while it was reaches about four times.
Physical and Mechanical Properties of Fly Ash-Bottom Ash Geopolymer Mixtures on Expansive Clay Soil Stabilization as a Subgrade Material
Authors: Wijaya Miguel Felix , Ismanti Sito , Satyarno Iman 
Published: December 2024

Abstract
The presence of expansive clay causes roads to undergo damage such as wavy, cracked, and even potholes. This type of soil shows that the soil is prone to swelling and shrinking. A base soil handling method against the effects of swelling and shrinking is chemical soil stabilization such as mixing the soil with lime, cement or additional materials. In this study, the stabilization method used was the fly ash and bottom ash geopolymerization reaction. Fly ash and bottom ash is an effective alternative to replace cement. Fly ash and bottom ash with addition of alkali activators of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) can serve as a binder similar to cement. This study aimed to improve the physical property and mechanical property tests of the soil such as bearing capacity and swelling potential as a requirement for subgrade. All physical property test results revealed that using fly ash-bottom ash geopolymer paste can improve qualities such as specific gravity, Atterberg limit, and grain size to improve expansive clay soil. Likewise, the mechanical property test results showed that the subgrade stabilized with fly ash-bottom ash geopolymer can increase its strength to surpass the requirements for road subgrades.

Published: December 2024

Abstract
Valuing the reconstruction of historic buildings is a complex and challenging task due to the unique nature of these structures and the uncertainties involved in estimating the scope of work. This study aimed to bridge the gap between traditional construction practices and modern economic frameworks by developing a comprehensive methodology for the valuation of construction works on historic buildings. Focusing on the Czech Republic, the study analysed the tender budgets of 21 reconstruction projects to be carried out between 2020 and 2023. The analysis compared tender prices with standardised indicative prices to identify significant discrepancies and the reasons for them. The proposed methodology integrated market-based price analysis and traditional pricing tools, providing a robust framework for accurate cost estimation. This approach not only ensured the preservation of the cultural value of historic buildings, but also provided a practical, financially sound strategy for their restoration. The findings of this study provide valuable insights for stakeholders involved in the pricing and budgeting of restoration projects, helping to refine cost estimation methodologies and improve the efficiency and accuracy of budgeting processes.

Published: December 2024

Abstract
The transition to a circular economy (CE) has become a crucial global objective, with the aim of promoting sustainable development while minimizing resource depletion and environmental degradation. Nevertheless, there are a lot of challenges that need to be overcome before CE principles are feasible to apply in the construction industry, particularly in areas like East Java, Indonesia. Thus, in order to integrate CE concepts into East Java’s construction industry, this paper investigates the critical success factors (CSFs). This study’s research approach consists of a thorough literature review, a questionnaire survey for data collection, and a thorough analysis of the data using mean score ranking and fuzzy synthetic evaluation (FSE). The analyses revealed 40 significant success factors for CE adoption in the architecture, engineering, and construction (AEC) sector of East Java’s construction industries. Furthermore, this study discovered six CSF categories that have a substantial impact on the success of CE adoption through FSE analysis. However, the three most significant categories are policy, technology, and commitment and competency. The results of this study provide crucial recommendations to the East Java government and stakeholders in the AEC sector.
Producing Sustainable Lightweight Geopolymer Concrete Using Waste Materials

Published: December 2024

Abstract
A research has been undertaken to investigate the possibility of producing sustainable lightweight geopolymer material by using waste zeolite (zeolite molecular sieve) as aluminates and silicates source and at the same time as lightweight medium. This was done by totally or partially replacement of fly ash by waste zeolite particles. Six geopolymer mixes were designed and produced using different source materials (fly ash F, fly ash C and zeolite) and alkaline solution of sodium silicate and sodium hydroxide. From the results, it was found that using fly ash C resulted in producing geopolymer mix with higher density than those made with fly ash F (Gf mix). However, replacing the fly ash totally with the zeolite particles helped in producing lightweight geopolymer concrete (1600 kg/m3) by achieving about 27% weight reduction and gaining about 5.1 MPa compressive strength. Not only reducing CO2 emissions by adopting zeolite- based geopolymer binder (instead of cement paste) but also achieving operational energy saving by producing lightweight concrete was obtained from producing lightweight geopolymer concrete as constructional material.

Authors: Kramarić Tomislava Pavić , Miletić Marko 
Published: December 2024

Abstract
This study examines the impact of the introduction of the euro on firm performance of non-financial firms listed on the Croatian capital market. Croatia adopted the euro as its sole legal tender on January 1, 2023, becoming the 20th member of the euro area. While the macroeconomic effects of euro adoption have been widely studied, its microeconomic implications, particularly on firm performance, remain underexplored. This research fills this gap by analyzing firm-specific determinants and their performance before and after euro adoption over 2019-2023. Using a sample of 25 non-financial companies listed on the Zagreb Stock Exchange, we employ panel data estimation techniques to evaluate the influence of euro adoption on corporate performance, incorporating variables such as firm size, leverage, firm openness or international sales, liquidity, and euro dummy variable. The results reveal that introducing the euro had a significant positive impact on firm performance, with implications for investment strategies and international competitiveness. This study is the first to investigate the euro's effect on firm performance in Croatia, offering valuable insights for policymakers and contributing to the broader literature on currency adoption and firm dynamics.

Published: December 2024

Abstract
Modifying cytosine by adding a methyl group in CpG dinucleotides within DNA sequence has several functions, but acts primarily as an important regulatory mechanism of mammalian gene expression. This consequently affects the phenotypic characteristics of the organism. The methylation profiles can be altered as a consequence of various environmental influences, age, disease, or diet, and can serve as biomarkers of important production and health traits. In this regard, the methylation profile analysis techniques are important. In the present study, we proposed and tested specific oligonucleotide primers for the bisulphite-sequencing polymerase chain reaction (BSP) analysis of the bovine GSTP1, GSTA4, and AChE genes, to optimize this approach for future studies of the methylation status of these genes. BSP can be used, for example, to study the effect of different pesticides and their combinations on the methylation of these and other bovine genes.

Abstract
Distributed denial of service (DDoS) attacks pose a significant security risk, particularly with the increasing reliance on cloud computing and information technology (IT). These attacks not only allow unauthorized users to access services but also deny legitimate users the ability to utilize them. Traditional antivirus solutions and firewalls prove insufficient in detecting DDoS attacks within large networks. Intrusion detection systems (IDS) are essential for detecting unauthorized or malicious activities and ensuring the confidentiality, integrity, and availability of services. However, traditional IDS often rely on predefined signatures and patterns, making them susceptible to evasion tactics. In response, this research introduces a deep learning (DL)-based IDS that integrates convolutional neural networks (CNN) with principal component analysis (PCA) and explores the application of vision transformers (ViT). The proposed hybrid model was tested on the CICDDoS2019 dataset, achieving a notable improvement in detection accuracy. Specifically, the CNN-based model initially identified DDoS attacks with an accuracy of 99.72%. Upon integrating ViT, the model’s accuracy further improved to 99.99%. This innovative approach signifies a considerable advancement in the detection capabilities for DDoS attacks and underscores the potential for integrating more sophisticated DL models into cybersecurity defenses.

Blended learning поколения Z: технология возможностей
Authors: Толстикова И.И. , Игнатьева О.А. , Кондратенко К.С. , Плетнев А.В. 
Published: December 2024

В данной статье авторы исследуют специфику восприятия представителями поколения Z образовательной технологии blended learning, активно внедряемой в учебный процесс во время пандемии, вызванной COVID-19. Мотивом, подтолкнувшим коллектив авторов провести подобное исследование, стала общественная дискуссия о новых форматах обучения и их эффективности. При этом голос ключевых стейкхолдеров, т.е. самих обучающихся, в данной дискуссии не был так отчетливо слышен. Чтобы прояснить позицию студентов и выявить причины, формирующие эту позицию, коллектив авторов провел опрос студентов в различных вузах г. Санкт-Петербурга. Опрос показал, что позиция «цифровых аборигенов» представляет собой синтез консервативной и либеральной точки зрения – студенты достаточно высоко оценивают потенциал новых форматов обучения и возможностей, которые они открывают, однако на сам процесс обучения и его архитектуру они предпочитают относиться достаточно консервативно. На основе полученных данных был проведен факторный анализ, результаты которого подтвердили изначальное предположение о синтетичности позиции представителей поколения Z и позволили структурировать причины специфичности позиции. Исследование является промежуточным в серии работ коллектива авторов о поколении Z. Авторы полагают, что изучение восприятия «зумерами» blended learning имеет существенное значение для исследования не только поколенческой аутентичности, но и новых форм взаимодействия с техникой современного общества в целом.
This paper explores the specifics of Generation Z perception of blended learning technology, which was actively introduced into the educational process during the pandemic caused by COVID-19. The motivation that prompted the team of authors to conduct such a study was the public debate about new learning formats and their effectiveness. At the same time, the voice of key stakeholders, i.e. students themselves, was not so clearly heard in this discussion. The survey showed that the position of "digital natives" is a synthesis of conservative and liberal point of view - students quite highly appreciate the potential of new learning formats and the opportunities they offer, but they prefer to treat the learning process itself and its architecture rather conservatively. Based on the data obtained, a factor analysis was conducted, the results of which confirmed the initial assumption about the synthetic position of representatives of Generation Z and allowed us to structure the reasons for the specificity of the position. The authors believe that the study of "Zumers'" perception of blended learning is a new form of interaction with technology in modern society as a whole.
The duality of Russia’s domestic and international cultural narratives: a cinematic analysis of Russian films in European perception (2021-2023)
Authors: Peiling L. 
Published: December 2024

This article examines the dichotomy between Russia’s domestic cultural narrative and its international cultural diplomacy as conveyed through russian films released between 2021 and 2023, focusing on «The Last Frontier» («Последний рубеж», 2020) and «No Looking Back» («Без оглядки назад», 2021) for their patriotic messaging aimed at domestic audiences, «Dear Comrades!» («Дорогие товарищи!», 2020) and «Captain Volkonogov Escaped» («Капитан Волконогов бежал», 2021) for their more introspective narratives presented to international viewers. In this paper we will try to examine how these films help support the continuity of Russia in world culture, and build up unity from within. Drawing on Stuart Hall audience reception theories encoding/decoding model and J. Nye's concept of soft power, the paper explores how europeans read these films against a backdrop of geopolitical tensions. It was that self-critical impulse of russian culture as an internal corrective to the euphemisms, misplaced heroism and nostalgias it indulges in this day; a balance with global projection not yet quite lost.
В этой статье рассматривается дихотомия между внутренним культурным нарративом России и ее международной культурной дипломатией, выраженная в российских фильмах, вышедших в прокат в период с 2021 по 2023 год, с акцентом на «Последнем рубеже» («Последний рубеж», 2020) и «Без оглядки назад» («Без границ», 2021) за их патриотический характер. послание, адресованное внутренней аудитории: «Дорогие товарищи!» («Дорогие друзья!», 2020) и «Капитан Волконогов сбежал» («Капитан Волков бежал», 2021) за их более интроспективные рассказы, представленные международным зрителям. В этой статье мы попытаемся рассмотреть, как эти фильмы помогают поддерживать преемственность России в мировой культуре и укреплять единство изнутри. Опираясь на теорию кодирования/декодирования зрительского восприятия Стюарта Холла и концепцию мягкой силы Дж. NYE, в статье исследуется, как европейцы воспринимают эти фильмы на фоне геополитической напряженности. Это был тот самокритичный импульс русской культуры, который позволил ей внутренне скорректировать эвфемизмы, неуместный героизм и ностальгию, которым она предается по сей день; баланс с глобальными проекциями еще не полностью утрачен.
Зарубежный опыт использования внебюджетных экологических фондов в рамках низкоуглеродного развития экономики
Authors: Лозовский Д.С. 
Published: December 2024

Развитие того или иного сектора экономики напрямую зависит от государства, поскольку реализация национальных программ или льготное субсидирование кредитов для реализации проектов обеспечивается за счет бюджетных средств. Развитие низкоуглеродной экономики не является исключением особенно с учетом возросшего внимания к экологии в ХХI веке. Зарубежные страны активно используют внебюджетные фонды как источник накопления средств для дальнейшего инвестирования в экологические проекты, которые помогут снизить выбросы парниковых газов. В данной статье будет рассматриваться опыт зарубежных стран по созданию системы внебюджетных экологических фондов, механизма их функционирования для создания системы использования внебюджетных экологических фондов в Российской Федерации в рамках развития низкоуглеродной экономики.
The development of a particular sector of the economy directly depends on the state, since the implementation of national programs or preferential subsidization of loans for the implementation of projects is provided at the expense of budgetary funds. The development of a low-carbon economy is no exception, especially given the increased attention to the environment in the 21st century, foreign countries are actively using extra-budgetary funds as a source of accumulation of funds for further investment in environmental projects that will help reduce greenhouse gas emissions. This article will consider the experience of foreign countries in creating a system of extra-budgetary environmental funds, the mechanism of their functioning for creating a system of using extra-budgetary environmental funds in the Russian Federation as part of the development of a low-carbon economy.

Comparative analysis of oral cavity organ reconstruction methods with axial and free innervated flaps
Authors: Reshetov I.V. , Zakirova A.A. 
Published: December 2024

The success of microsurgical reconstruction is currently assessed not only by the survival of free flaps and adequate replacement of defects but also by the aesthetic result, donor site morbidity and functional outcome achievement. A rational consequence of this evolution is the use of free innervated flaps. This literature review provides examples of the use of different types of flaps for the oral cavity reconstruction, from simple ones to the more complicated and modern, requiring microsurgical techniques, including the restoration of sensory nerves.
Успех выполнения реконструктивных микрохирургических операций в настоящее время оценивается не только выживаемостью свободных лоскутов и адекватным замещением дефектов, но также эстетическим результатом, сведением к минимуму морбидности донорских участков и, что более важно, достижением хороших функциональных результатов. Рациональным следствием этой эволюции является использова- ние функциональных свободных реиннервируемых аутотрансплантатов. В данном литературном обзоре приведены примеры различных типов лоскутов, используемых для реконструкции органов головы и шеи от локальных к более сложным, что требует владения микрохирургической техникой, и в т.ч. восстанов- ления чувствительных нервов.
