Published: June 2024

Islamic educational institutions during the Abbasiyah era possess a number of uniqueness. This has been shown through the contribution of those earlier islamic scholars, resulting in critical meaning in today’s education. The practice that occurs in Islamic educational institutions are derived from the teacher-student relationship, especially during the 8th-12th century. Hence, this study aims to examine the basis of teacher-student relationship thinking that occurred in Islamic educational institutions of the Abbasiyah era. Among the most prominent institutions studied are the research centers, mosques, and schools. The data obtained generally through an exploration of primary and secondary historical sources. In addition, data analysis employed interpretive and descriptive methods. Findings showed that the the fundamental thoughts of teacher-student relationship existing in the most important Islamic educational institutions reveal four important aspects namely spiritual values, manner teaching (adab), wisdom, and scientific spirit. Thus, these elements need to be re-emphasized in the teacher-student relationship through current educational institutions so that the authority of knowledge can be situated in its proper place.

Authors:   , Camargo Beatriz Fernandes de
Published: June 2024

Os distúrbios comportamentais em aves mantidas sob cuidados humanos são comumente causados pela falta de expressão de comportamentos naturais, como voar, socializar e forragear. Esses comportamentos alterados, como arrancar penas e agressividade, são indicativos de estresse e ansiedade. O enriquecimento ambiental (EA) é uma abordagem que visa promover comportamentos naturais em cativeiro, incluindo o manejo alimentar adequado. Este trabalho revisou o conceito, técnicas e benefícios do EA nestas aves. A metodologia incluiu uma revisão de literatura, abrangendo várias bases de dados. O EA pode ser categorizado em cinco abordagens, incluindo aspectos sociais, físicos, sensoriais, cognitivos e alimentares. O manejo alimentar, uma vertente do EA, envolve oferecer uma dieta adequada com base na compreensão da biologia da espécie. Exemplos práticos de aplicabilidade do EA foram discutidos, destacando a importância de proporcionar um ambiente enriquecido para o bem-estar das aves. A criação de aves como animais de estimação apresenta desafios adicionais, e os distúrbios comportamentais podem surgir devido à falta de estímulos naturais. A compreensão da fisiologia e comportamento natural das aves é essencial para prevenir esses problemas e promover seu bem-estar em cativeiro.

Published: June 2024

Background and purpose: Mortality after major lower extremity amputations is high and may depend on amputation level. We aimed to examine the mortality risk in the first year after major lower extremity amputation divided into transtibial and transfemoral amputations.Methods: This observational cohort study used data from the Danish Nationwide Health registers. 11,205 first-time major lower extremity amputations were included from January 1, 2010, to December 31, 2021, comprising 3,921 transtibial amputations and 7,284 transfemoral amputations.Results: The 30-day mortality after transtibial amputation was overall 11%, 95% confidence interval (CI) 10–12 (440/3,921) during the study period, but declined from 10%, CI 7–13 (37/381) in 2010 to 7%, CI 4–11 (15/220) in 2021. The 1-year mortality was 29% overall, CI 28–30 (1,140 /3,921), with a decline from 31%, CI 21–36 (117/381) to 20%, CI 15–26 (45/220) during the study period. For initial transfemoral amputation, the 30-day mortality was overall 23%, CI 22–23 (1,673/7,284) and declined from 27%, CI 23–31 (138/509) to 22%, CI 19–25 (148/683) during the study period. The 1-year mortality was 48% overall, CI 46–49 (3,466/7,284) and declined from 55%, CI 50–59 (279/509) to 46%, CI 42–50 (315/638).Conclusion: The mortality after major lower extremity amputation declined in the 12-year study period; however, the 1-year mortality remained high after both transtibial and transfemoral amputations (20% and 46% in 2021). Hence, major lower extremity amputation patients constitute one of the most fragile orthopedic patient groups, emphasizing an increased need for attention in the pre-, peri-, and postoperative setting.

Identifying Host and Bacterial Biomarkers to Predict Sepsis
Authors:   , Lewis Matthew L.
Published: June 2024

Sepsis is a serious concern for healthcare programmes worldwide and is associated with 11 million deaths annually. E. coli accounts for 20% of bloodstream infections worldwide and is responsible for 17% of sepsis related mortality. Early diagnosis and treatment are critical and delays in initiating antimicrobial therapy are linked to mortality. Identifying biomarkers to predict patients that might succumb to sepsis is vital to aid in early diagnosis. It was hypothesised that E. coli bacteraemia isolates and isolates from different sources of bacteraemia would elicit a distinctive host response and be genetically unique. Blood culture positive isolates (n=165) were collected from the Hywel Dda University Health Board. Most of the isolates were assigned to the B2 and D phylogroups and belonged to either ST131 or ST73. Antimicrobial resistance in the collection was lower than national averages. Host models of infection were used to identify phenotypic responses of the bacterial collection. IL-8 and MIP3α were increased following stimulation by bacteraemia isolates compared to non-pathogenic strains. Greater IL-8 in whole blood was associated with a urinary and abdominal bacteraemia. Isolates that were resistant to human plasma elicited a higher IL-6, IL-8 and resistin response in whole blood compared to plasma sensitive isolates. Blood culture positive bacteraemia isolates had significantly more virulence factors than control isolates. Bacteraemia isolates expressed more P fimbriae genes. The S fimbrial adhesin genes were found to be significantly different between urinary and abdominal isolates. Abdominal isolates had significantly more sfaC (32%) while urinary isolates had more sfaX (22%). GWAS analysis revealed 6 potential gene targets based on bacterial phenotypes. These were ynbC, yhgE, ybjE, yejF, tufB and yohF. The results contained within this thesis describe new targets for predicting bacteraemia and sepsis and underline the importance of using host and pathogen as sources for biomarkers.

Published: June 2024

It was studied the Processes of ensuring chemical stability (stabilization) of starch nitrate obtained by nitration of starch by two ways: nitric acid and nitric-sulfuric acid mixture. It has been confirmed that, in the first case, starch nitrate has much higher stability due to the absence of low-stable sulfuric acid esters. It is shown that to ensure it in this case, 10 minutes of washing of starch nitrate in 0.19 m3/kg of hot water (95 °С) is sufficient. It was established that in the case of nitration with nitric acid, an increase in the nitrogen content in starch nitrate, which characterizes the amount of nitroester bonds in it, leads to a decrease of the temperature atthe beginning of active decomposition, whichapproaches 168 °C for the maximum nitrogen content (14.14 %). This temperature is proposed as an indicator for evaluation of starch nitrate chemical resistance.The obtained data are necessary for the development of starch nitrate production technology.

Global climate changes are taking place on our planet, which cause an increase in the average annual temperature of the atmospheric air, and, therefore, rapid melting of glaciers on all continents and an inevitable rise in the level of the world ocean. This, in turn, can lead to "environmental" wars, a brutal struggle for survival resources, and powerful migration processes. At the same time, one of the main reasons for such global changes and processes is the huge amount of emissions of greenhouse gases and soot particles into the surface layer of the atmosphere (troposphere), caused by anthropogenic and man-made activities, outdated energy-intensive technologies that involve the excessive extraction and use of carbon-containing raw materials, their burning and emission into the atmosphere. However, an alternative to this in post-war Ukraine can only be decarbonization and eco-modernization of its economy based, first of all, on renewable energy sources (in particular, the inexhaustible energy of the Sun), resource-saving, closed, recycling, emission-free and other modern innovative environmental protection and energy-efficient technologies. That is, humanity must definitely go on the path of "green" transformation of not only the economy, but also the greening of all other spheres of life (Hura, Petruk, 2021).

Published: June 2024

This article is devoted to the problem of using microwave radiation as a potentially effective method of cleaning wastewater from organic compounds. The problem of cleaning wastewater from organic contaminants in the food industry requires highly effective methods since protein compounds in wastewater can cause environmental hazards and complicate the cleaning process. The purpose of the work was to investigate the effectiveness of using microwave radiation to purify wastewater from organic compounds, particularly protein impurities, and to establish the possibilities of this method for improving the process of water purification in the food industry. The article mainly examines the use of microwave radiation for this purpose and analyses its effect on proteins usually present in wastewater from the food industry. Experimental studies have shown the possibility of adequate wastewater treatment using microwave radiation. The advantages of using microwave heating, as well as its speed and regulation accuracy, are analysed, making this method attractive for use in wastewater treatment and other industrial production processes. The study includes an analysis of microwave radiation's effect on proteins commonly present in wastewater from the food industry. The research methodology involves modelling the composition of wastewater and using a microwave oven to process protein solutions. The results of the experiments demonstrate the possibility of adequate wastewater treatment using microwave radiation, which opens up prospects for further use of this method in industry and environmental protection. The results indicate the success of using microwave radiation to purify wastewater from organic compounds, notably protein pollution.

Published: June 2024

Kerinci Seblat National Park in Bengkulu, Indonesia, was gazetted by the Indonesian government, and its overlaps with forests occupied by most indigenous communities made their farming activities in the area illegal. People were prohibited from accessing and expanding their farming areas in the national park, threatening their livelihoods. The livelihood diversity index (LDI) and livelihood asset index (LAI) were used to explore the livelihood systems of these communities. This study also examines the effect of livelihood assets on livelihood diversity and analyzes livelihood strategy choices using Giddens’ structuration theory. A quantitative survey combined with in-depth interviews was conducted in two villages with different land types: wetlands (rice fields) and drylands (farmlands). This study found that the communities diversified their livelihoods into eight types of livelihood strategies. Almost all livelihood indicators were different, and the differences in livelihood asset indicators affected the LDI. As a process of structuration, communities have diversified their livelihoods into farm (e.g., annual and perennial crops), off-farm (e.g., farm wages), and non-farm (e.g., services and government transfer) activities. Rural households have modified their social and physical structures to secure their livelihoods by optimizing agricultural intensification technologies or by seeking non-agricultural income. Households decide whether to specialize or diversify their livelihoods based on factors such as the area of cultivated land, number of crops cultivated, distance of the farming location from the house, total household income, non-farm income, and reciprocal relationships.

Published: June 2024

Medicare, a major healthcare program under the Centers for Medicare & Medicaid Services (CMS) has extended telemedicine services within several states in the US for different specialties for which it reimburses in order to establish a qualitative and accessible healthcare system. In parallel, it has been seen that teleradiology services by American Board Certified radiologists based offshore can significantly supplement healthcare delivery in the US by mitigating the shortage of radiologists and enhance outcomes of patient care especially for after-hours emergency work. Teleradiology can help workflow by improving workload distribution, lowering the cost of reporting, shortening turn-around-time for reports, and improving quality of life for staff. The aim of the article is to provide perspective on Medicare reimbursement of offshore telereporting services. We submit that due to its value proposition and contribution to healthcare, offshore telereporting by American Board Certified Radiologists is worthy of Medicare reimbursement and should be re-evaluated for its credits.

Published: June 2024

The aim of the study was to determine the effect of zinc application in different doses with organic fertilization on the genera composition and the number of CFU (colony-forming units) of entomopathogenic fungi (EPF) in the soil. The experiment was carried out in greenhouse condi-tions. Soil samples for testing were collected in the third year of the experiment (spring, autumn), where the research objects were I – dose of zinc: control – lack (0) and 200, 400 and 600 mg Zn kg–1 of soil; II – no fertilization – 0 (CO), spent mushroom substrate (SMS), chicken (ChM) and cattle manure (CM). Entomopathogenic fungi were isolated using the method of isolation on a selective medium. In the course of the research, EPF of the genus: Beauveria, Metarhizium, Cordyceps and Lecanicillium were determined. The conducted research showed that entomopatho-genic fungi of the Metarhizium genera formed the most CFU in spring. In the autumn there were three times less of them. Statistical analysis showed that the number of CFUs of the identified genus of fungi (on average) in soil samples significantly depended on the dose of zinc applied, organic fertilization and the genus of fungus, but only for Metarhizium spp.

Estimation of the coefficient of permeability as an example of the application of the Random Forest algorithm in Civil Engineering
Authors: Dzięcioł Justyna , Sas Wojciech
Published: June 2024

A new world record for crude steel production was recorded in 2021, which increased by 3.8% over 2020. This also affected the amount of slag produced with this production. Total waste from industrial and construction production throughout the European Union accounts for as much as 48%. Therefore, waste management should provide for the recovery of as many resources as possible. European Union strategies in line with the circular economy objectives focus on ensuring policy coherence in the areas of climate, energy efficiency, construction and demolition waste management and resource efficiency. Slags are a material of interest to researchers in terms of their use in construction. Slags, on the one hand, are materials that are becoming better understood on the other hand, we are making sure of the heterogeneity of these materials. The characteristics of physical properties of slags are influenced by many factors, including the furnace split in which they are produced. This prompts the search for tools to help determine the parameters of slags based on already available data. The study aimed to verify the hypothesis that it is possible to determine the parameter of the filtration coefficient, relevant to applications in earth structures using the machine learning algorithm – Random Forest. In the study, two types of material were analysed: blast furnace slag and furnace slag. The results of the analysis yielded a high coefficient of determination (R2) – 0.84–0.92. This leads us to believe that the algorithm may prove useful in determining filtration parameters in slags.

The paper focuses on the system reliability of steel trusses with correlated variables. The correlation between bearing capacities of bars was considered. Two static truss schemes were considered. Nodal forces were the only load. The Finite Element Method analysis was conducted in Robot Structural Analysis program. To conduct system reliability analysis it is essential to find cut-sets, it was realized by stiffness matrix spectral analysis. Then reliability analysis was performed in Sysrel module of Strurel computing environment. First Order Reliability Method was used as the base, Subset Simulation method was used to check the correctness of the results. The sensitivity analysis of reliability index enabled the authors to draw conclusions, which variables have the greatest influence on the reliability of the structure. The effects of actions and bearing capacities were assumed to be the only random variables and that the excessing the bearing capacities of bars is the only way the structure can get into failure area.
Modelling the hot metal desulfurization process using artificial intelligence methods
Authors: Podolska Angelika , Falkus Jan
Published: June 2024

The objective of conducted research on the hot metal desulfurization process was to determine the key process parameters that impact the ultimate outcome of desulfurization. As a result, the noticeable outcome of implementing these measures should be the improvement of quality control. In order to determine these parameters, used artificial intelligence methods like as neural networks (ANN). On the basis of the production data collected from the actual metallurgical aggregate for hot metal desulfurization, neural networks were built that used quantitative data (mass of hot metal, mass of used reagents, etc.) and qualitative data (chemical analysis of hot metal). The parameters of the desulfurization process were divided into state parameters and control parameters. From the point of view of the technology of conducting the desulfurization process and building an on-line model, only control parameters can be changed during desulfurization. To describe the problem of predicting change in the sulfur content during the hot metal desulfurization process is sufficient an MLP type neural network with a single hidden layer. Adopting a more complex network structure would probably lead to a loss of the ability to generalise the problem. The research was carried out in STATISTICA Automated Neural Networks SANN.

The FRP reinforcement gained importance due to high tensile strength, high durability and ecological friendliness [1–7]. Its usefulness as the internal or Near Surface Mounted reinforcement in bent concrete elements has already been proven. Though, in terms of the compressive behaviour of the bars and concrete elements incorporating them, there are still few experimental and numerical considerations, especially when high temperatures are considered. This article contains further considerations on the performance of concrete columns with BFRP main reinforcement in fire resistance tests on the basis of previously presented authors’ numerical analyses. Comparative analysis in terms of temperatures, deformations and stresses of concrete columns with BFRP and steel main reinforcement in fire resistance tests is presented by the example of two columns, for which also experimental investigations were performed. Also, a comparative analysis of stress-strain relations for BFRP, steel and concrete at temperatures up to 600°C is presented. It can be concluded that BFRP bars’ properties are strongly different when compressive and tensile performance is considered, especially at elevated temperatures. Tensile strength was higher for BFRP than steel at room temperature, but along with temperature growth, it came the other way (at around 600°C). The compressive strength of the BFRP bars was higher than the value for concrete, but only for temperatures lower than 200°C.

The research focuses on solving the important problem of slope stability in the field of civil engineering. The study adopted an advanced strength double reduction coefficient method for slope stability analysis, which considers the different influence weights of cohesion and internal friction angle, and reduces them with different reduction coefficients to describe the stability of the slope. The simulation experiment results indicate that the attenuation degree of cohesion and internal friction angle affects slope stability. When the reduction coefficient of cohesion increases to 1.737 and the reduction coefficient of internal friction angle increases to 1.201, the slope is prone to instability and failure, and the safety factor of the calculated result is 1.493. Moreover, when the anti-slip pile is set in the middle of the slope (1/2), and the slope is in a critical state, the bending moment and shear force suffered by the anti-slip pile are both maximum, so the reinforcement effect is also the best.

In recent years, bridge safety accidents caused by insufficient shear bearing capacity of bridges have attracted increasing attention. The main causes include internal factors such as insufficient bridge section and deterioration of steel bars, as well as external factors, for example, vehicle load surge and improper maintenance. To address this issue to some degree, this article adopts the method of strengthening RC beams with ultra-high performance concrete (UHPC) and conducts parameter analysis using finite element method, taking into consideration the influence of four parameters: reinforcement material, reinforcement thickness, reinforcement length, and reinforcement form on the shear strengthening characteristics of RC rectangular beams. After obtaining the optimal reinforcement plan through parameter analysis, the author applied the research results to an existing bridge with insufficient shear strength. It then turned out that the shear bearing capacity of the reinforced bridge’s inclined section increased by approximately 27.1%. Simple and fast in construction, this reinforcement method is one of the methods that is effective to increase cross-section reinforcement; besides, it features good economic characteristics and applicability.
Structural optimization design of multi ribbed composite wall of building components under seismic load based on random optimization algorithm and resilience model
Authors: Hu Xu , He Lu
Published: June 2024

The multi ribbed composite wall structure is also known as the multi ribbed wall panel light frame structure. This structure is suitable for housing construction in the residential field. The special structural failure process and mode of multi ribbed composite walls are different from traditional walls. To fully utilize the excellent structural performance in building construction and improve the seismic performance of the building, based on the transformation principle of subset optimization algorithm for optimization problems, a constrained subset simulation optimization algorithm suitable for optimizing the maximum displacement angle of multi ribbed composite wall panels is designed. The Bayesian algorithm is used to construct a restoring force model for multi ribbed composite wall panels. The constrained subset simulation optimization algorithm and resilience model are used to optimize the seismic performance of 4-layer multi ribbed composite wall panels. The results show that the section height and the equivalent slant support width of the continuous column for the 4-story multi ribbed composite wall panel change from discrete distribution to aggregation with the increase of iteration. Finally, the sampling is stable in the 9th floor. At this time, the section height of the continuous column is 230 mm, and the equivalent slant support width is 525. After optimization, the failure probability of both extreme displacement angle states has decreased. When the peak ground acceleration is 1.0 g, the optimized second limit state failure probability is less than 100%. When the peak ground acceleration value is between 0.2 g and 0.6 g, both limit states show a rapid upward trend. The constrained subset simulation optimization algorithm and Bayesian quantitative resilience model proposed in the research can effectively optimize the seismic performance of multi ribbed composite walls.
Hydration heat generation and dissipation in diaphragm walls
Authors: Grabowski Łukasz , Mitew-Czajewska Monika
Published: June 2024

This study focuses on the complex dynamics of heat dissipation within diaphragm walls during concrete hydration, crucial in construction engineering. Experimental measurements from three sites in Poland, featuring diaphragm walls of varying thicknesses, ranging from 1 to 1.5 meters, were compared to a numerical model. The model, using a Finite Difference Method, incorporated stages of execution of adjacent panels and their thermal influence. The results closely mirrored the measured temperatures, validating the accuracy of its predictions. Despite minor discrepancies, mostly within ±3°C, the method effectively approximated real-life scenarios. Suggestions for model enhancements include incorporating the effect of concrete admixtures and refining the modeling of sequential panel execution. The thermal soil parameters, their possible range, and their impact on hydration heat dissipation in deep foundations emerged as crucial insights. This research serves as a foundation for deeper investigations into early-age behavior in deep foundations, aiming to extend the analysis to stress and strain domains to unravel characteristic cracking patterns observed in diaphragm walls.
