Authors: Khan Md. Nasir Uddin , Haque Md. Nozibul
Published: January 2024

This paper evaluated aquifer properties in a part of Southwest Bangladesh to categorize groundwater potential using catastrophe theory (CT). Satellite image, lithologic, pumping test, rainfall and groundwater monitoring data were utilized for this purpose. Lithology-based stratigraphic cross- sections confirm six vertically distributed layers, classified into aquitard composed of surface clay with silt and very fine-grained sand with thickness varying from 1 to –24.4 m, whereas the aquifer comprising fine to coarse sand with 3–67 m thick. Pre- and post-monsoon average annual groundwater levels fluctuate from in 3.12 to 3.86 m and 6.97 to 8.36 m, respectively, while average annual recharge ranges from 0.4 to 0.59 m/yr. Groundwater potential index (GWPI) values, validated with specific capacity records, classified the study area into three zones with GWPI of 0.72–0.81 (moderately good), 0.81–0.87 (good), and 0.87–0.96 (very good), covering 25.44%, 47.60%, and 26.96% of the area, respectively. Sensitivity analysis identified rainfall as the most influential and land type as the least influential factor in defining groundwater potentiality. These results can serve as a foundation for the formulation of guidelines and recommendations for the governmental and affiliated agencies for future groundwater exploration, planning, and management.

This study discusses foreign fighters who take part in the Ukrainian armed conflict. The aim of this study is to know about the history of the armed conflict of Ukraine, study the relevance of International Humanitarian Law to foreign fighters, and study the implementation of Human Rights obtained by foreign fighters based on International Humanitarian Law. The used is juridical-normative legal research or also called document research with secondary data as the main source. Researchers conduct legislative studies to see synchronization between legislation. Data were collected using literature review techniques, such as perusing, analyzing, and drawing conclusions from relevant documents. The results of this study conclude, first, the history of the Ukrainian armed conflict starting from the independence of Ukraine and culminating in the Russian special military operation that occurred on February 24, 2022. Second, the relevance of international humanitarian law to foreign fighters has no specific definition describing foreign fighters and only foreign terrorist fighters. Third, the implementation of human rights against foreign fighters is an inviolable or inalienable human right. However, in its implementation there are still many violations that occur in the armed conflict of Ukraine. Several methods are needed to overcome this problem, namely, the need to increase understanding and awareness regarding IHL and human rights, especially for foreign fighters, to all parties and, make policy recommendations regarding clarity of understanding for foreign fighters, which can then be used as a guide for policymakers and practitioners to increase the certainty of humanitarian protection for foreign fighters.

Adolescents are one of the age groups that are vulnerable to experiencing nutritional problems because they can determine their own lifestyle. Apart from diet, clean and healthy behavior is one of the indirect causes that influences nutritional status. Knowledge about clean and healthy living that teenagers have can determine their clean and healthy behavior attitudes and practices. Low clean and healthy behavior can be a risk factor for infectious diseases which can reduce nutritional status. This study aims to examine the relationship between knowledge, attitudes and practices of clean and healthy behavior and the nutritional status of adolescents. This research uses a cross-sectional study. The research was conducted in June-November 2023 at Al-Washliyah 1 Private High School, Medan City and Bandung Foundation High School, Deli Serdang Regency. The selection of research locations was carried out using purposive sampling. The research population was students in grades X to XII aged 14-18 years in both schools. The sampling technique used cluster sampling, the total subjects were 100 students from each school. Data was collected through questionnaire interviews in the form of characteristics, knowledge, attitudes and practices of clean and healthy behavior. Nutritional status data was obtained by directly measuring body weight using a digital scale and height using a microtoise and then determined using a z-score from the body mass index according to age (BMI/U). Data analysis was carried out using the Spearman Test. As many as 31% of teenagers have abnormal nutritional status (undernutrition, overnutrition and obesity). The bivariate test results showed that there was a significant relationship between knowledge (p=0.005), attitudes (p=0.001), and practice (p=0.000) of clean and healthy behavior and adolescent nutritional status. As many as 65.5% of teenagers with low clean and healthy behavior attitudes have abnormal nutritional status.

A dipeptidil-peptidáz-4-gátlók szerepe a 2-es típusú diabetes mellitus kezelésében napjainkban
Authors: Harangi Mariann , Tóth Nóra , Katona Éva
Published: January 2024

A dipeptidil-peptidáz-4 (DPP-4) az inkretinrendszer szabályozásának kulcsszereplője, mivel képes katalitikusan inaktiválni a glükagonszerű peptid-1-et (GLP-1) és a glükózdependens inzulinotróp peptidet. A DPP-4-gátlókat széles körben alkalmazzák 2-es típusú diabétesz (T2DM) kezelésére a mellékhatások, köztük a hipoglikémia kialakulásának alacsony kockázata miatt. A DPP-4-gátlók közül öt (szitagliptin, vildagliptin, alogliptin, szaxagliptin és linagliptin) alkalmazását hagyták jóvá a hatóságok, melyek hazánkban is elérhetőek. Bár a preklinikai vizsgálatok a DPP-4-gátlók kifejezett terápiás potenciálját igazolták kardiovaszkuláris megbetegedésekben, minden, a DPP-4-gátlókkal elvégzett hosszú távú kardiovaszkuláris biztonságossági tanulmány non-inferioritást támasztott alá a major kardiovaszkuláris végpontok tekintetében. Ezzel szemben a legújabb gyógyszercsoportok, köztük a nátrium-glükóz transzporter-2 (SGLT-2)-gátlók és a GLP-1-receptoragonisták, csökkentették a major kardiovaszkuláris események kialakulásának kockázatát. Ezért az utóbbi években a DPP-4-gátlók szerepe módosult; ezeket a szereket második vonalbeli szerként ajánlják alkalmazni metforminnal, illetve SGLT-2-gátlóval kombinálva a glikémiás kontroll hatékonyságának növelése céljából, különösen krónikus vesebetegségben szenvedő és idős T2DM-es betegek esetén. Összességében a DPP-4-gátlók biztonságos, költséghatékony orális vércukorcsökkentő szerek, melyeknek továbbra is helye van a T2DM-es betegek kezelésében, és alkalmazásukkal széles körű tapasztalattal rendelkezünk.

The Variational Iteration Method for a Pendulum with a Combined Translational and Rotational System
Authors: Amir Muhammad , Ashraf Asifa , Haider Jamil Abbas
Published: January 2024

The dynamic analysis of complex mechanical systems often requires the application of advanced mathematical techniques. In this study, we present a variation iteration-based solution for a pendulum system coupled with a rolling wheel, forming a combined translational and rotational system. Furthermore, the Lagrange multiplier is calculated using the Elzaki transform. The system under investigation consists of a pendulum attached to a wheel that rolls without slipping on a horizontal surface. The coupled motion of the pendulum and the rolling wheel creates a complex system with both translational and rotational degrees of freedom. To solve the governing equations of motion, we employ the variation iteration method, a powerful numerical technique that combines the advantages of both variational principles and iteration schemes. The Lagrange multiplier plays a crucial role in incorporating the constraints of the system into the equations of motion. In this study, we determine the Lagrange multiplier using the Elzaki transform, which provides an effective means to calculate Lagrange multipliers for constrained mechanical systems. The proposed solution technique is applied to analyse the dynamics of a pendulum with a rolling wheel system. The effects of various system parameters, such as the pendulum length, wheel radius and initial conditions, are investigated to understand their influence on the system dynamics. The results demonstrate the effectiveness of the variation iteration method combined with the Elzaki transform in capturing the complex behaviour of a combined translational and rotational system. The proposed approach serves as a valuable tool for analysing and understanding the dynamics of similar mechanical systems encountered in various engineering applications.
Thermal and Visualisation Study of the HFE7100 Refrigerant Condensation Process
Authors: Bohdal Tadeusz , Sikora Małgorzata , Formela Karolina
Published: January 2024

Technological advances are contributing to the search for highly efficient energy designs, and increasing interest in compact heat exchangers. Indeed, small channel diameters determine large heat transfer coefficients and condition a significant heat transfer area about the overall volume of the heat exchanger, as well as a smaller amount of refrigerant flowing in the system. Nevertheless, the operating stability and energy efficiency of compact heat exchangers are influenced by two-phase flow structures, which depend on thermal flow parameters. Knowledge of the structures formed during the condensation process is therefore essential for optimising the operation of refrigeration and air-conditioning equipment. This article presents the results from experimental studies of the HFE7100 refrigerant, from the hydrofluorocarbon group, condensation process in mini-channels with hydraulic diameters dh = 2.0 mm, 1.2 mm, 0.8 mm and 0.5 mm. Thermal flow characteristics were determined, and the forming structures of two-phase flow were recorded. The results of visualisation were subjected to morphological image analysis, based on a special algorithm written in MATLAB software. The algorithm makes it possible to determine the void fraction, which is necessary for calculating the vapour quality, as well as the area of vapour bubbles and their number, directionality and length along the x- and y-axes.

Two 11-year-old patients suffered traumatic anterior dental injuries resulting in ankylosis and subsequent extractions. After consulting the multidisciplinary team, the developing lower second permanent premolars with immature root apices were chosen to replace the injured upper incisors using autotransplantation.

Results

Six months after autotransplantation, orthodontic treatment was initiated to close the upper arch spaces, correct the dental midline deviation and to camouflage the transplanted teeth. Normal overbite and overjet were achieved and Class I canine and molar relationships were obtained. After the removal of the orthodontic appliances, composite resin restorations were placed on the upper anterior teeth. During a 4-year follow-up, the pulp vitality of the transplanted teeth was normal with no periodontal nor pathological findings. Pulp canal obliteration with adequate apical length was observed in all the teeth.

Conclusion

In children presenting with upper incisors lost to trauma, autotransplantation of developing lower premolars into the upper anterior region followed by orthodontic space closure can be a viable treatment modality producing satisfactory aesthetics and function.

Published: January 2024

We continue the formal development of the application of piecewise linear functions and centroids in the area of fuzzy set theory. The corresponding piecewise linear functions are symmetrical and composed by absolute function. In this paper we prove that the membership functions of isosceles triangle type and isosceles trapezoid type can be constructed by functions of this type.

A large number of concrete bridges need to be repaired due to durability problems. This research focuses on evaluating the bond quality of the repair material, which has the highest influence on the durability of the repair. Onsite experimental research is performed on the vertical surfaces of the column of the Klara Jug bridge, which is located in the southern part of the Zagreb. Since the experimental research is carried out in parallel with the ongoing repair works on other bridge elements, the experimental conditions correspond to the real construction site conditions. Simulation of the actual site rehabilitation process was carried out on the test fields, which included removal of the damaged concrete by hydrodemolition at a depth of 1.5–2 cm, washing of the concrete by roto nozzle and wet spraying of the repair mortar. The results of the pull-off tensile bond strength show that there is an optimum period for spraying of repair mortar after washing the concrete surface. Optimal time for application of mortar is 90 min after completion of washing of the vertical concrete surface by the roto nozzle. In other weather conditions, the application time depends on the expected evaporation of water from the surface. The tensile strength of the bond between concrete and the repair mortar is 62% lower if the concrete is not washed by the roto nozzle prior to the application of the repair mortar. This investigation can serve as a practical guide for the repair of vertical surface of concrete elements of bridges, overpasses and viaducts.
The role of competency-based certification in ensuring sustainable project delivery

Published: January 2024

An increasing number of organisations are basing their operations on temporary forms of work such as projects to cope with the needs of the modern business environment, which consequently leads to a significant growth in the demand for competent individuals who can not only adequately manage projects, but also seize the opportunities that this new way of doing business brings in the creation of strategic value for organisations. To be considered competent in the field, individuals should therefore demonstrate a certain level of knowledge, skills and abilities that are assessed, developed or improved through certification systems. Although professional certification was previously driven exclusively by the aspirations of individuals for improvement in a business context, to ensure a more professional project practice, the conditions for performing this type of work are starting to be more formalised at the level of employers (requirements in job advertisements) or the state (regulation of certification bodies or legally prescribed requirements for project positions). With the aim of examining the attitude of project professionals towards the competency-based certification in the field of project management and its legal regulations, as well as its role in ensuring the sustainable project delivery, quantitative empirical research was conducted among 246 certified project, programme and portfolio managers in Croatia. The obtained results not only indicate the importance of certification in project delivery and continuous professional development of individuals, but also emphasise insufficient recognition of certification within organisations, its connection with career progress and compliance of practices at the state level.
Impact of Takt-Time Planning on Plastering Work Productivity: A Case Study
Authors: Kozlovská Mária , Kempecova Daria
Published: January 2024

This article aims to analyze productivity issues during the implementation of plastering works on the case study of a residential complex. The results of the study revealed that establishing a proper work schedule and adhering to the Takt schedule resulted in a 19% increase in plastering productivity compared to non-Takt schedules. Furthermore, the study identified the existence of waste, which had a negative impact on the progress of the plastering work and could have been prevented through better project planning during the initial project phases.

Published: January 2024

The partial replacement of cement by supplementary cementitious materials is an opportunity for reducing fossil energy consumption and greenhouse gas emissions. In this study, forty (40) pastes were formulated by applying a 4-factor mixture plan, consisting of cement, glass powder (GP), superplasticizer and water. Third order models “special cubic” established for the flow time, spreading diameter, and flow velocity, responses were statistically significant. The analysis of the models allowed the study of the individual and combined effects of the different factors, highlighting the predominant effect of the superplasticizer on the dispersion GP fines. The multi-criteria optimization allowed the development of two optimal pastes SCP1 and SCP2 incorporating 25 and 7% GP, respectively. SCP1 was chosen because at this GP amount, unlike at 28 days, the paste presents the best strengths at 90 days with 4.5% increase for flexural tensile strength and 15.69% increase for compressive strength while maintaining satisfactory workability.

Improving productivity in construction projects has long been a major concern, and much research has been carried out to try to ameliorate construction productivity. To this end, this study aims to improve and increase the productivity rate of flat slab formwork used in residential construction projects. A survey consisting of 150 questionnaires was undertaken to identify the factors that influence on the productivity. Based on the relative Importance Index (RII), data on eleven factors deemed to affect productivity were selected. A collection of 100 data points from various sites were utilized to develop two models. Firstly, an Artificial Neural Network (ANN) model was employed, and secondly, a parametric approach was investigated. The data were divided into two sets, with 70% of the data used for training and the remaining 30% used for testing. The models’ performance was evaluated using the Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE) values. In the test phase, the artificial neural network model yielded an MSE value of 2.6610e−4 and a MAPE value of 4.9227, whereas the parametric model produced an MSE of 0.040 and a MAPE of 9.525. It was found that the artificial neural network model provided reliable prediction accuracy compared to the parametric model. However, the artificial neural network approach can be selected as a robust model in predicting and controlling the productivity rate in local construction projects by using the developed model based on the identified factors.

Published: January 2024

Recycling industrial waste to obtain secondary raw materials is a key focus of environmental policy and circular economy strategies. One such industrial waste, recycled brick waste (RBW), is characterized by high pollution and low recycling rates. This paper evaluates the effects of graded replacement of various RBW sizes as a substitute for coarse and fine natural aggregate (NA) on the mechanical properties and durability of cement treated base (CTB). The novelty of this study lies in the durability evaluation of four types of CTB, including natural, recycled, and mixed CTB. RBW and NA materials are characterized and compared, and the mechanical properties and durability of CTB with RBW materials are analyzed and compared to CTB with 100% NA. The results show that the mixes containing waste bricks exhibit comparable mechanical characteristics and could be used in layers of pavement foundations. Additionally, the durability of the mixes containing RBW yields better results compared to blends containing NA.

Research on the antioxidant activity test and toxicity test of leaf extract (Ayapana triplinervis (ValH) RM) has been conducted against the larval shrimp (Artemia salina Leach). The dried leaves weighing 500 grams were macerated using methanol, filtered, and concentrated using a rotary evaporator. Methanol crude extract was fractionated with n-hexane, ethyl acetate, and methanol water. Based on Test Phytochemicals screening on secondary metabolites showed that the crude extract of methanol, n-hexane fraction, and methanol-water containing secondary metabolites alkaloids, flavonoids, and phenolic in ethyl acetate fraction of the content of secondary metabolites, alkaloids, and flavonoids, and the fraction of n-hexane and ethyl acetate contain steroids. In contrast, the crude extract of methanol and n-hexane fraction contains phenolic compounds. Test mortality of shrimp larvae (Brine Shrimp Lethality Test) showed mortality of shrimp larvae (Artemia salina Leach) using Probit analysis (SAS) to determine the value of 50% Lethal Concentration (LC50). In this test, the most active is the methanol crude extract of archery leaves, with a value of 18.8608 ppm, in a test of antioxidant activity using DPPH free radical reduction in the spectrophotometer and IC50 values obtained. In methanol crude extract was 430.73 ppm; n-hexane fraction was 168.5 ppm; ethyl acetate fraction was 114.87 ppm; and methanol-water fraction was 37.23 ppm
