COMPARISON OF SOIL DEFORMATION PARAMETERS DETERMINED BY OEDOMETER AND TRIAXIAL TESTS
Authors: Zakarka Mindaugas , Dirgėlienė Neringa , Skuodis Šarūnas , Fiodorov Michail
Published: June 2024

One of the main parameters characterizing soil deformations is the deformation modulus, which can be determined in the laboratory with an oedometer or a triaxial test device. The authors conducted experimental tests with the oedometer and triaxial test apparatuses with eight different type soils. Experimental data for eight types of sands, clays, silts with specially mixed grain size distribution curves, having different non-plastic fines contents, mean grain sizes and uniformity coefficients, were analyzed. In general, the deformation modulus obtained from the triaxial test is higher than that obtained from the oedometer test, due to the difference in loading conditions. It is important to take into account the specific properties of the soil, like particles form, and test conditions when comparing the values of the deformation modulus obtained by performing different laboratory tests. Also, it is very important to know the magnitude of the loads and the type of foundation when assessing ground deformations.
GYROID CELL USAGE IN TOPOLOGY OPTIMIZATION OF LOAD-CARRYING PARTS
Authors: Kegl Marko , Harl Boštjan , Dinevski Dejan , Predan Jožef
Published: June 2024

This paper discusses the implementation and usage of a gyroid cell in topology optimization of load-carrying structural parts. Conventional topology optimization relies on a linear elastic model and the strain energy density field of the structure in order to optimally distribute the material within a given domain. This procedure may take place either on a completely unrestricted topological domain space or on a restricted preconfigured domain. The latter option is often chosen in order to enforce a cellular type structure of the part. In this context, surface-based cells like the gyroid cell may be an attractive option under special circumstances. For that reason, this paper addresses briefly the problem of numerical processing of the topological domain space in case of gyroid cell usage. In this context, a numerically efficient and stable procedure is proposed, suitable to be engaged on very large finite element meshes. Furthermore, an interesting numerical example demonstrates that conventional topology optimization of a linear model can even be used to tune the plastic dissipation of a structure under large deformations.
RECYCLING METHODS FOR STEEL FIBER REINFORCED CONCRETE
Authors: Kaeseberg Stefan , Schmidt Elisabeth , Holschemacher Klaus
Published: June 2024

The favorable impact of steel fibers in concrete is well known. Steel fibers can affect various fresh and hardened properties of concrete, for instance the appearance and propagation of cracks in the concrete matrix. Thus far, extensive research has been conducted to describe and to analyze those phenomena. Furthermore, Steel Fiber Reinforced Concrete (SFRC) is state of the art and is used extensively in industrial floors, walls, and ceiling constructions. But, beside the beneficial impact, the recycling of SFRC and, in particular, the separation of crushed concrete and steel fibers should be focused too. Only a few research programs are described in literature and comprehensive suggestions or guidelines are missing completely. So, a first test program was carried out to evaluate the usual procedure to break the concrete with a jaw crusher and to separate the contained steel via magnet. In tests, the amount and the type of the fibers used were varied as well as the concrete strength. The tests suggest that a certain amount of fibers can be separated, but the majority of fibers is still bound to the crushed concrete. Via sieving, it is possible to further separate concrete still containing fibers from aggregates without fibers. Conglomerates of broken concrete and fibers may be crushed again afterwards, but, allegedly, the success of the described procedure strongly depends on the fiber amount and the concrete properties. Furthermore, the available test data is too small to sufficiently describe the entire recycling path, making further research inevitable.
DECISION SUPPORT MODEL FOR SELECTING PROJECT DELIVERY METHODS IN SUSTAINABLE CONSTRUCTION PROJECTS
Authors: Ahmed Salma , El-Sayegh Sameh
Published: June 2024

Selecting the appropriate delivery approach holds a huge significance level, especially in sustainable construction projects, which exhibit unparalleled attributes compared to traditional counterparts. This paper introduces a novel decision support model aimed at assisting owners in this crucial nomination process. Critical review analysis was used to identify 36 important nomination factors for project delivery methods and categorized into traditional and sustainability-specific factors. In order to determine how well typical delivery methods—Design-Bid-Build (DBB), Design-Build (DB), and Construction Management at Risk (CMR)—meet the nomination factors, a poll was subsequently sent to construction experts in the United Arab Emirates. Paired analyses of the three delivery systems were performed using the Analytical Hierarchy Process. The results showed that DBB, the traditional delivery technique, is not up to the increased needs for integration and collaboration in sustainable construction projects. Alternative delivery techniques, like CMR and DB better meet these needs. Three functions make up the suggested decision support model: screening of nomination factors, evaluation of project delivery methods, and strategic alignment of project goals and project delivery methods nomination factors. Users of this model can alter the weights assigned to the nomination factors that are essential to accomplishing the objectives of their green construction projects. It also offers an extensive set of nomination factors, enabling choice determiners to formulate a convincing argument for pinpointing the best delivery method for their green construction project.
A LITERATURE REVIEW ON RISK FACTORS ON INTERNATIONAL CONSTRUCTION PROJECTS
Authors: Akyol Muhammet , Polat Gul , Gurgun Aslı Pelin
Published: June 2024

Internationalization is one of the most critical decisions for construction companies. Although expanding into new markets promises several benefits such as new job opportunities, increases in market share and profit margins, etc., it is exposed to risks and difficulties, which in turn result in poor project performance in terms of delays and cost overruns. Therefore, construction companies should thoroughly recognize the potential risk factors and develop proper risk management strategies against these risk factors. This study reviews the recent studies on risk factors on international construction projects, which might cause delays and cost overruns, in order to help construction companies that mostly undertake international construction projects in recognizing risk factors and developing their risk response strategies against them. For this purpose, semi-systematic literature review was conducted, 32 journal articles from 14 academic journals reviewed in depth, and 23 different risk factors were identified. “Host government related risk”, “Resource price fluctuations”, “Unavailability of resources in the host market”, and “Contractor’s lack of managerial skills” were found to be “highly cited risk factors”. On the other hand, “Adverse public attitude”, “Project specification and standard problems”, “Technology and proprietary information sharing problems”, and “Virtual Risk” were found to be “lowly cited risk factors”.
DEFORMATION OF END CROSSBEAMS OF STEEL BRIDGES RELATED TO SUSTAINABILITY OF BRIDGE JOINTS
Authors: VAN BOGAERT PHILIPPE
Published: June 2024

Both AASHTO and Eurocode stipulate that the deflection of end crossbeams of bridges must be limited to 5 mm under the influence of frequent traffic loads. After a thorough literature review and survey of data from manufacturers of bridge joints, it must be concluded that the background of this requirement is not really based on facts. Durability of bridge joints certainly does not appear to be the basis. Another valid reason can be the comfort of road user, which is effectively disturbed by driving over bumps and thresholds. Although the road user expects light shocks at the end of a bridge, the acceleration inside the vehicle must be limited. Therefore, the state of a wheel driving over a threshold has been studied, by applying analytical equations taken from literature and extended. These allow a fairly accurate simulation of the state. Force required to cross the threshold produces an acceleration of wheel, which is transmitted to vehicle's sprung chassis. In the latter one finds the acceleration to which persons are subjected. Several values of comfort can be considered. It turns out that 5 mm limit is very conservative, and one could easily allow up to double the end cross beam’s deflection.
EXPLORING THE SUSTAINABILITY OF CONCRETE BRIDGES

Published: June 2024

After the construction boom of the past 30-40 years, United Arab Emirates has been left with many costly structures that may or may not fulfill modern sustainability requirements. With the on-going economic recession seen by most of the world and a higher awareness among the population regarding the environmental and societal impact of construction, engineers and designers are carrying out sustainability studies for all kinds of infrastructure. Although most of past research has focused on sustainability rating of buildings, recent advances in this area shows a heightened interest in sustainability assessment of bridges as well. Several of the key sustainability indicators for buildings are also applicable for bridge; quantitative (construction cost and assembly, transportation of materials, service life, environmental impact, etc.) and qualitative (aesthetics, safety features, etc.). This paper contributes to an ongoing research project aimed at developing a sustainability rating system for bridges in the UAE. It includes a comprehensive survey designed to evaluate the relevance of current sustainability indicators for bridge projects within the region. The findings and analysis of this survey are discussed, providing insights into the adaptation of these sustainability metrics for UAE bridges.
A SIMPLE APPROACH FOR PREDICTING CURVATURE IN CONCRETE MEMBERS REINFORCED WITH STEEL FIBERS AND BARS
Authors: Kaklauskas Gintaris , Sokolov Aleksandr
Published: June 2024

The paper proposes a simple deflection model for concrete bending members reinforced with steel fibers and bars (further denoted as R/SFRC members). Most of the current design approaches for such elements require the knowledge of the residual strength of steel fiber reinforced concrete (SFRC) in tension with the latter characteristic being obtained from standard bending tests. The involvement of extra tests hampers a wider application of R/SFRC structures in practice. The proposed model does not require the characteristic of the residual strength. It was derived using an inverse approach earlier proposed by the authors. The resultant tensile force of SFRC acting in the tension zone of a R/SFRC beam was derived from the experimental moment-curvature diagram. A load level was identified at which the resultant tensile force reached zero, implying that the section stiffness equals to the stiffness of the fully cracked RC section. The proposed model in a simple way expresses curvature via the curvatures at a cracking load and the load corresponding to the stiffness of the fully cracked RC section. The predictions by the proposed model were checked against independent test data.
COMPARATIVE EVALUATION OF “LEED” CERTIFIED SCHOOLS WITH “YES-TR” IN THE CONTEXT OF “GREEN CERTIFICATION”
Authors: AKYEL IZEL , KOMURLU RUVEYDA
Published: June 2024

With the emergence of green building concept in the construction sector, the increase in green building production has resulted in green building certification systems. It is important to establish these certification systems on a national scale for reasons such as the compatibility of sustainable architecture with local conditions and differences in the legislation of countries. It is inevitable to change the criteria of the certification system in accordance with the function of the building. As the schools are directly related to learning as well as providing the health and comfort to the users, there are internationally specialized certification systems for green schools. In this study, some of the LEED-certified schools in Turkiye were compared; these buildings were evaluated within the framework of the “Green Certificate (YeS-TR)” introduced by the Turkiye’s Ministry of Environment, Urbanization and Climate Change in 2022. The main categories of “LEED v2009 for Schools” and “Green Certificate” were compared; while “sustainable sites” and “regional priority” categories in “LEED v2009 for Schools” are not included in the “Green Certificate”, the main category of “integrated design, construction and management” and “life cycle assessment” were not met in “LEED v2009 for Schools”. As a result of the study, various suggestions were made for the development of certificates in this context.

Published: June 2024

The modern integration of digital technologies into the educational process requires additional study, given the opportunities that this process opens up. The purpose of the article is to study the use of digital technologies in STEM education through the prism of researching the main challenges and prospects. To achieve this goal, the methods of questionnaires and interviews were used. In particular, 65 teachers of higher education institutions were interviewed, whose opinions became the basis for forming a generalised picture of the study. The results show that modern teachers actively use digital technologies in STEM education. The average level of digital technology use among STEM teachers is high: 43 people (65%) use technology at grade levels 4 and 5. However, this intensive use of digital technologies in STEM education raises both challenges and opportunities. In particular, today's teachers often face limited access to the necessary technical infrastructure, which can limit their ability to implement digital tools. Poor quality of internet connection can affect the smoothness and efficiency of using online resources. Insufficient training of teachers in the use of digital technologies is also a significant challenge. Increasing the availability of digital resources for teachers will make learning more accessible and diverse. Cooperation between universities and technology companies also opens up new opportunities for the development of STEM education. The conclusions emphasise that such interaction facilitates the exchange of experience, access to advanced technologies and resources, and creates conditions for the implementation of joint projects and programmes.

Akceptacja, krytyka, odrzucenie. Reakcje na Veritatis splendor
Authors: Nowosad Sławomir
Published: June 2024

Od dnia swojej publikacji encyklika Veritatis splendor Jana Pawła II doczekała się wyjątkowo licznych reakcji i omówień pochodzących z różnych stron chrześcijańskiego i teologicznego spektrum, nie tylko katolickiego. Niniejszy artykuł dokonuje analizy recenzji i komentarzy, które ukazały się przede wszystkim w języku angielskim, choć uwzględnia się także niektóre, ważniejsze teksty włoskie i hiszpańskie. Wielu recenzentów encykliki wyraża uznanie i akceptację dla papieskiego nauczania, opinie innych autorów są mieszane – pozytywne i  negatywne, natomiast są i  takie, które jednoznacznie krytykują papieską wizję moralności chrześcijańskiej, a nawet ją odrzucają. W swej treści recenzje te odnoszą się bądź do całościowej wizji encykliki, bądź do wybranych zagadnień szczegółowych, jak sposób korzystania z Pisma Świętego, prawo naturalne, konsekwencjalizm i proporcjonalizm oraz czyny intrinsece malum. Odrębna część artykułu poświęcona jest niektórym aspektom krytyki wizji życia moralnego w ujęciu Jana Pawła II, jaką od lat formułuje Charles Curran.

Drepanocytosis is a genetic disease relevant for its epidemiological, clinical and socio-economic aspects. In our country the prevalence is highly uneven with peaks in former malaria areas, but migration flows in recent years have led to significant changes. In this document we review the screening programs currently existing in Italy with particular emphasis on newborn screening, which in other countries around the world, including within Europe, is at most universal and mandatory. The essential laboratory issues are reviewed, from sampling aspects (cord blood or peripheral), to the analytical (analytical methods dedicated to neonatal screening and adult carrier detection) and post analytical (reporting, informative) ones. An economic analysis based on data collected in the province of Modena is also proposed, clearly showing that neonatal screening is also beneficial from an economic point of view.
Governing Consumer Information in the Digital Age: Lessons from a Controversy Between a Food Rating App and Processed Meat Manufacturers
Authors: Lambert Élisabeth , Smolinski Jan
Published: June 2024

This article examines the legal response to a controversy on dietary information in the context of commercial court and appellate court rulings. Against a backdrop of health and environmental crises, the construction of information on such risks has become a sensitive issue for market actors, as a result of which courts are asked to arbitrate conflicts. This is particularly important at a time when informational mediations carried out by new actors increasingly take the form of digital ratings and augmented information. The dispute involving the firm Yuca and the French agro-industrial processed meat sector is a case in point. This paper analyses the structural arguments put forward in this legal dispute at the first instance and appeal stages. In the light of law and socio-economics, it untangles questions pertaining to the link between denigration and freedom of expression and the definition of the role of scientific research and consensus in the decisions. This leads us to shed light on the contents of the changing missions of two central types of actors: the mediators who monitor and regulate market practices and the judges that arbitrate these mediations and settle controversies.

This study investigates the mechanical properties of hybrid composites composed of web kapok fibers and fiberglass reinforced with epoxy for potential application in the marine industry. The web kapok fibers were carefully processed using a carding technique to ensure better alignment and consistency. Various composite configurations were produced, and extensive mechanical testing was conducted, including flexural, tensile, and impact tests. The results revealed that the presence of two web kapok fiber layers within the composite significantly increased flexural strength and flexural modulus compared to pure fiberglass laminates. However, a single layer of web kapok fabrics exhibited the highest tensile strength, although it decreased with additional layers. The impact strength of these hybrid composites also showed promising results, especially when compared to raw fiberglass composites. Moreover, these composites exhibited improved resistance to water absorption and corrosion, making them potentially suitable for marine applications. This research highlights the potential of web kapok/fiberglass hybrid composites as an eco-friendly alternative for marine engineering, with implications for reduced environmental impact and sustainable technology in the industry.

Published: June 2024

Neurodegenerative disorders, including Alzheimer’s disease (AD), Parkinson’s disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington’s disease (HD), pose significant global health risks and represent a substantial public health concern in the contemporary era. A primary factor in the pathophysiology of these disorders is aberrant accumulation and aggregation of pathogenic proteins within the brain and spinal cord. Recent investigations have identified extracellular vesicles (EVs) in the central nervous system (CNS) as potential carriers for intercellular transport of misfolded proteins associated with neurodegenerative diseases. EVs are involved in pathological processes that contribute to various brain disorders including neurodegenerative disorders. Proteins linked to neurodegenerative disorders are secreted and distributed from cell to cell via EVs, serving as a mechanism for direct intercellular communication through the transfer of biomolecules. Astrocytes, as active participants in CNS intercellular communication, release astrocyte-derived extracellular vesicles (ADEVs) that are capable of interacting with diverse target cells. This review primarily focuses on the involvement of ADEVs in the development of neurological disorders and explores their potential dual roles – both advantageous and disadvantageous in the context of neurological disorders. Furthermore, this review examines the current studies investigating ADEVs as potential biomarkers for the diagnosis and treatment of neurodegenerative diseases. The prospects and challenges associated with the application of ADEVs in clinical settings were also comprehensively reviewed.

Published: June 2024

This study investigates the potential use of Yellow River sand (YRS) sourced from the lower reaches of the Yellow River in China as a sustainable and cost-effective substitute for quartz sand in engineered cementitious composites (ECCs). This region accumulates around 400 million tons of sand annually. The study evaluates the impact of different YRS replacement percentages (0, 25, 50, 75, and 100%) on mechanical and microstructure properties under freeze-thaw conditions, focusing on assessing the ECC durability during cooling cycles. The results show that YRS exhibits a smaller normal distribution of particle sizes compared to that of quartz sand and a 5.77 times greater specific surface area, affecting the ECC particle size distribution. After 300 cooling cycles, the R25 group maintains 97.5% of the initial mass and 79.4% of flexural strength, indicating superior durability. The R25 group also demonstrates a minimal decrease of 11.5% in equivalent bending strength, reaching a level of 104.4% compared to R0. The R25 group’s porosity is 30.80%, with an average pore size of 20.47 mm, showing 1.3% and 6.7% decreases compared to the R0 group. Additionally, this study establishes a failure progression equation using the Weibull probability distribution model, with calculated values closely aligning with measured values. Overall, this study recommends using YRS as a sustainable ECC material.

This study examined the methods for preparing biocarbon from Teff hay (TBC) and thiol-grafted seed gum of Tamarindus indica (TH@TI-TBC) with the purpose of removing cadmium (Cd) from polluted electroplating waste water. To improve biocarbon adsorption, seed gum and thiol were added in a two-step combination. At a pH of 5.5, the most effective Cd adsorption was seen with TH@TI-TBC (261.47 mg g−1). While comparing to the Freundlich and Temkin models, the Langmuir and pseudo-second-order kinetic models found to be the best fit to the obtained adsorption data. After being treated with electroplating wastewater having 30 mg−1 L of cadmium, TH@TI-TBC was able to remove up to 89 % of the Cd, proving its effectiveness in dealing with adsorptive removal of Cd. Experimental studies and computational analyses revealed that electrostatic interaction and surface complexation were the principal underlying processes for Cd removal by TH@TI-TBC. In addition, an innovative material that can transform the waste into a product for environmental remediation must be developed using the vast amounts of Teff hay that are generated as agro-residue. So, this work proved that TH@TI-TBC can be made from Teff hay biocarbon could be a potential candidate for removing Cd from industrial wastewater.

Objective

This study aimed to assess selenium status in South Korean pregnant women and its impact on maternal thyroid function and pregnancy outcomes.

Methods

‘Ideal Breast Milk (IBM) Cohort Study’ included 367 pregnant women out of 442 participants and categorized into three groups based on plasma selenium levels: deficient (< 70 μg/L), suboptimal (70–99 μg/L), and optimal (≥ 100 μg/L). During the second or third trimester, various blood parameters, including selenium, thyroid-stimulating hormone, free T4, free T3, and anti-thyroid peroxidase antibody levels, were measured. Thyroid parenchymal echogenicity was assessed as another surrogate marker for thyroid autoimmunity using ultrasonography.

Results

The median plasma selenium was 98.8 (range: 46.7–206.4) μg/L, and 30 individuals (8%) were categorized as deficient, while 164 (45%) were classified in the suboptimal group. Selenium deficiency was associated with markers of autoimmune thyroiditis, including positive anti-thyroid peroxidase antibody results (13.3 (deficient) vs 4.6 (optimal) %, P = 0.031) and thyroid parenchymal heterogeneity on ultrasound (33.3 (deficient) vs 14.6 (suboptimal) vs 17.3 (optimal) %, P = 0.042), independently of gestational age. The incidence of severe preeclampsia was higher in the group not taking selenium supplements, particularly among those with twin pregnancies, compared to the group taking selenium supplements (0 (selenium supplement) vs 9.0 (no supplement) %, P = 0.015).

Conclusion

Pregnant women experience mild selenium deficiency, which can lead to significant health issues including maternal thyroid autoimmunity and obstetrical complications during pregnancy. Guidelines for appropriate selenium intake according to the stage of pregnancy and the number of fetuses are needed.

With the Taliban’s resurgence in Afghanistan, a unique situation arises regarding their pursuit of international recognition. On the one hand, their close ties to terrorist organisations like al-Qaeda and their questionable sources of funding raise significant concerns about the consequences of granting them international legitimacy. Conversely, the international community, particularly the United States, appears hesitant to intervene at this juncture, prompting thoughtful reflection. Specifically, post-recognition, there is a looming question about whether the Taliban will persist in endorsing terrorist activities or relying on illicit funding methods. In such a scenario, determining the justification for humanitarian interventions becomes a critical consideration. Moreover, the extent of intervention during the transitional phase from lawlessness to lawfulness in Afghanistan, where extreme crimes are prevalent, demands scrutiny. In this context, it is pertinent to explore Immanuel Kant’s perspectives on humanity and his work Perpetual Peace as they align with the current situation. Therefore, this paper aims to assess both sides of the issue through a Kantian lens to gauge the appropriateness of humanitarian intervention under these unique circumstances. Ultimately, this analysis could shape a new framework for interventions in dire situations involving “crimes against humanity” or threats to human lives stemming from such conditions.
Administración desleal y negocios de riesgo
Authors: Perdomo Torres Jorge Fernando
Published: June 2024

En estas líneas se pretende estudiar los elementos más importantes del tipo penal del artículo 250b sobre administración desleal. El propósito es analizarlo desde una perspectiva material, es decir, yendo más allá de la simple explicación formal de los elementos típicos, acudiendo a las teorías de la posición de garante y de la imputación objetiva. Ello nos llevará a enfocarnos en el riesgo (permitido) como uno de los principales criterios de análisis en materia de criminalidad económica; solo aquel comportamiento que exceda los límites de lo permitido en las relaciones económicas complejas puede serle imputado a un administrador como conducta desleal. La necesidad de considerar el funcionamiento real económico de la empresa se expondrá de la mano del concepto de plan global empresarial.

The objective was to assess the cardiac risk of elderly individuals attending Basic Health Units (UBS) in the North and South zones of Aracaju, SE.  To achieve this objective, the study employed the Framingham Risk Score, which takes into account multiple cardiovascular risk factors, including age, blood pressure, heart rate, cholesterol levels, body composition, and other pertinent indicators. It's worth noting that some of these factors can be modified, while others cannot. A total of 76 elderly individuals participated in the study ( = 67 ± 6.07 years). The highest mean values for cardiovascular risk factors were found for total cholesterol ( =  199.10 ± 43.57 mg/dL) and low density lipoprotein ( =  129.57 ± 34.85 mg/dL), followed by the systolic blood pressure ( =  124.8 ± 19.88 bpm). The cardiovascular risk of the sample group was characterized as high ( =  0.29% ± 1.5%). Furthermore, the mentioned percentage delta reflects the change in value over a specific period, providing insights into relative changes in a dynamic context. The outcome of this study was a comprehensive assessment of the cardiac risk in these UBS attendees, contributing to the understanding and appropriate treatment of cardiovascular conditions in this population.
