Flow control for low-reynolds number airfoil performance enhancement using response surface methodology
Authors: Ndouba Ange Benai-dara  , ZhaoLin Chen  , Leon Kaswango Kanam
Published: December 2024

Low Reynolds number flows are characterized by boundary layer separation due to the effect of viscous forces. The separated flow may reattach through the exchange between the molecules resulting in Laminar Separation Bubble LSB. LSB, known for its detrimental effect on the performance is sensitive to the airfoil geometry. The current paper describes the use of trip boundary on the suction surface of SD7003 airfoil as flow control technique to enhance the airfoil performance at and using numerical analysis. Due to the complexity of finding the trip size and location, Response Surface Methodology RSM is used to obtain the optimum combinations between the height, width and the position of the turbulator. Thus, the design variables are the height [0.2mm,0.6mm], width [140mm, 200mm] and the position of the trip away from the leading edge [10%c, 25%c]. Using the Desirability approach with Nelder-Mead simplex algorithm, the trip location is found to be effective downstream the separation location of the untripped airfoil. At the optimum design parameters, the length of LSB has decreased by 2.32% and the airfoil performance increased by 6%.
Green Concrete: A step towards eco-friendly environment
Authors: Maninder Pal Singh
Published: December 2024

The building industry is embracing green concrete more and more since it has many inherent benefits and few drawbacks compared to traditional concrete. To encourage the usage of green concrete in the construction sector for significant infrastructure projects, more research and development projects, interdisciplinary collaborations, public awareness campaigns, materials and the creation of codes and standard documents will be necessary. Concrete contributes about 5% of global CO2 emissions since it is the second most utilized material after water. Reducing the environmental impact of cement and concrete, rather than replacing them with alternative materials, is the answer to this environmental issue. The ability to use green concrete in construction has enormous potential benefits for society's environment. It is reasonable to believe that technology will be created that will cut the CO2 emissions associated with the production of concrete in half. As society has grown more conscious of the deposit issues associated with residual products over the past few decades, demands, limitations, and levies have been put in place. The need for high-quality concrete products, the desire to lessen greenhouse gas emissions and carbon footprints, the need to conserve natural resources, and the limited amount of landfill space in urban areas are the main factors contributing to the growing demand for green concrete. Green concrete encourages the sustainable use of waste materials as substitutes for the traditional concrete-making materials. Green concrete is superior to regular concrete in many ways. Because it makes use of recycled materials and aggregates, it lessens the additional pressure on landfills and minimizes aggregate waste. Consequently, there are fewer net CO2 emissions. The economy also benefits greatly from material reuse. An essential component of sustainable development is green concrete. A common substitute of concrete in green building techniques is green concrete

SHARIA ECONOMIC LAW ANALYSIS ON ZAKAT MANAGEMENT AT BAZNAS BANDAR LAMPUNG CITY
Authors: Zaharah Rita , Fauzi Mohammad Yasir
Published: December 2024

This study examines the potential of zakat as an economic instrument that can enhance the welfare of the Muslim community if managed properly according to Sharia principles. In practice, zakat's collection, management, and distribution should comply with religious guidelines to be used productively as a community fund source. However, current zakat management faces challenges, such as the use of conventional banks for zakat collection, distribution that is more consumption-oriented, and a management process that is not yet effective. This research was conducted at BAZNAS in Bandar Lampung City using a descriptive qualitative approach. The results show that the use of conventional banks by BAZNAS is solely as a zakat collection medium, not as a manager, and is considered compliant with Sharia economic law, referencing Ibn Asyur's maqashid shari'ah, as it provides broad benefits. As an official zakat management institution in Bandar Lampung, BAZNAS strives to manage zakat by government regulations to improve community welfare through distribution models that include consumptive and productive empowerment approaches.

Authors: Saifuddin  , Riskiya Dwi Novem Wulandari  , Moh Khoirul Anam
Published: December 2024

This research aims to understand the characteristics and patterns of adolescent consumer behavior related to their participation in coffee shop culture and to determine the impact of adolescent consumer behavior on coffee culture from the perspective of Islamic Economics. The phenomenon of the increasing popularity of coffee shops among teenagers indicates a change in consumption patterns, which has the potential to lead to consumerist behavior. Consumerist behavior is considered excessive and inconsistent with the principles of justice and balance in wealth management. This research uses a qualitative method with a case study approach. The data sources consist of primary and secondary data. Data were obtained through in-depth interviews with teenage visitors to Cafe Rooster, observations, and documentation. The results of this study show that: 1) Coffee shops have become a symbol of social status and a popular gathering place among teenagers, driven by peer pressure and the desire for acceptance. Teenagers are driven to spend money at coffee shops to express themselves, seek enjoyment, and follow trends promoted through social media platforms like Instagram, Facebook, and Twitter, which also influence their purchasing decisions. 2) From the perspective of Islamic economics, the consumer behavior of teenagers in coffee shop culture has negative impacts, such as uncontrolled spending and being contrary to the principle of prudence in Islam, which is opposed to the value of blessings in Islam and has the potential to cause financial problems in the future. Therefore, a balance between consumption and saving needs to be maintained.

Published: December 2024

The growing awareness of the importance of halal products has significantly influenced various sectors, including the cosmetics industry. However, prior research has predominantly focused on halal food and beverages, while halal skincare products, such as Somethinc, have received limited academic attention. Furthermore, studies that integrate halal literacy, labeling, product quality, and price about purchase decisions, with a willingness to pay a premium price as a mediating variable, remain scarce. This study examines the influence of halal literacy, halal label, product quality, and product price on the purchasing decisions of Somethinc skincare products among Gen Z, mediated by willingness to pay a premium price. The research method used is quantitative, with primary data obtained through questionnaires. The sampling was conducted using purposive sampling, with a total of 272 respondents. The data analysis technique used is Structural Equation Modeling (SEM), analyzed using the software SmartPLS version 3. The results of this study indicate that the variables halal literacy, product quality, and product price do not directly affect purchasing decisions, while the halal label variable and willingness to pay a premium price directly influence purchasing decisions. The halal literacy and halal label variables do not affect willingness to pay a premium price, whereas product quality and product price variables do affect willingness to pay a premium price. Additionally, halal literacy and halal labels do not influence purchasing decisions when mediated by a willingness to pay a premium price, whereas product quality and product price do influence purchasing decisions when mediated by a willingness to pay a premium price.

A device to intensify preliminary softening of frozen overburden at open-pits of the permafrost zone
Authors: Hosoev D.V. , Burakov A.M.
Published: December 2024

The main challenges in mining frozen grounds in winter time are related to the topmost layer, which softening can provide optimal conditions for its removal. The article describes the developed patented device, which can be used in the openpit mining of mineral deposits in the permafrost zone, providing intensification of preliminary blastless softening of frozen overburden using surface-active substances (surfactants). It is emphasized that the technical task of the device is to maintain a constant level of solution in the boreholes without its overflow, ensuring continuous penetration of the surfactant solution into the cracks and pores of the ground mass due to the hydrostatic pressure of the surfactant solution itself. For this purpose, the device is fitted with a perforated dispenser to ensure a uniform, continuous supply of the surfactant solution. A dedicated hole or valve should be provided in the upper part of the shell to balance the pressure inside the tank with atmospheric pressure, and its lower part is covered with drilling fines to provide its vertical stability. An insufficient degree of implementing the surfactantbased methods of rock softening is noted, as well as the fact that the proposed device will cause a decrease in their strength and deformation properties and will allow, within certain limits, to control the state and properties of the mined rock mass in open-pit mines in the northern regions of the Russian Federation.
Assessment of the stress state of a rock mass using the blasting and vibroacoustic methods
Authors: Tyupin V.N. , Ponomarenko K.B.
Published: December 2024

In order to ensure safety at the level of -250 m in the Gubkin mine of KMAruda, the following activities were performed: assessment of the rock mass susceptibility to rock bumps using the vibroacoustic method, as well as determination of the stress state of the rock mass with the blasting method. As the result of experimental studies using the vibroacoustic method, a decrease of the stress state of the rock mass was found to vary from 17.5–92.5 MPa (at the entry contour) to 10–30 MPa at the distance of 1.8 m from the wall. The blasting method used at the level of –250 m of the Gubkin mine revealed that the stress state of the rock mass at the bottoms of the cutting and auxiliary holes is 21.9–33.5 MPa, while at the bottoms of the outer and trimming holes it varies within 55.7–65.1 MPa. The blasting and vibroacoustic methods for determining the stress state of the rock mass are similar in the physics of the process. When exposed to the detonation products or the drilling tools combined with the static rock pressure, a certain volume of rock mass is destroyed. The greater the static rock pressure, the greater the volume of destruction is under the same dynamic loads. Taking into account an increase of the stress state from the center towards the outline for the rock face plane, a numerical assessment of the stress state at the entry contour after blasting of the cutting, auxiliary and outer holes was carried out based on a theoretical formula. The calculations using the formula and based on the test data coincide, which indicates creation of residual stresses within the rock mass due to the sequential detonation of the explosive sets in the blast holes.

Published: December 2024

The use of ultrasound in the flame-photometric determination of sulfate-ions in water by the indirect potassium method was studied. At the same time, precipitation of sulfate ions was carried out with an excess of slightly soluble dry potassium barium phosphate salt. It is shown that the amount of potassium that has passed into the solution is proportional to the amount of sulfate ions in the analyzed sample. To improve the reproducibility and correctness of the obtained results, as well as to increase the expressivity of the analysis, the precipitation of sulfate ions was carried out under the influence of ultrasound with a frequency of 5.0 - 7.0 MHz, an intensity of 3.0 - 5.0 W/cm2 for a period of time ≥ 2,0 min. A method for determining sulfate ions in waters with mineralization up to 50 g/l has been developed, the range of determined concentrations of sulfate ions is 10 – 150 mg/l. The correctness of the obtained results (determined using standard water samples UkrNDIsil CRM 022.3-20s, CRM 022.3-20m and CRM 022.3-20vm) was for water with mineralization of 50 g/l - 92.5 - 93.1%, and for water with mineralization up to 10 g/l - 99.2 - 99.6%. The relative standard deviation of the analysis results did not exceed 0.051. Without the use of ultrasound, the quantitative determination of the content of sulfate ions is possible only in waters with mineralization up to 10 g/l with an accuracy of 90.2 - 91.0%.

Published: December 2024

Ultrasonic electromagnetic-acoustic transducers (EMAT) with permanent magnets are used to test ferromagnetic metal products. This leads to strong pressing of the EMAT to the metal, wear, and the appearance of coherent interference, which makes it impossible to carry out measurements and diagnostics. These disadvantages can be eliminated by introducing pulse magnets. The aim of the work is to determine rational geometric parameters of a pulse magnet for EMAT. To achieve this goal, a physical and mathematical problem was formulated and modeling was performed using the Comsol Multiphysics package. It was found that to ensure efficient operation of the EMAT, it is advisable to set the height of the pulse magnet within 50...60 mm, and the pole dimensions are 30x30...50x50 mm. Such parameters provide a quasi-stationary magnetic field induction value of at least 0.35 T in the range of ± 10 mm from the center of the pulse magnet pole.

The behavior of the dynamic system is characterized by a large set of experimental data. The character of this data changed in abnormal case of functioning or in system faults. The identification of the considerable changes from measurement results almost no using statistical methods is the feature of the article. For this purpose,the experimental data matrix and the singular value decomposition (SVD).The change in singular values occurs as a result of a significant change in the nature of the data.To make a decision regarding the system transition into anomalous mode, the distance in Euclidean space between the set of singular values for normal conditions of system operation and the set of such values for possible anomalous conditions is estimated.If this distance will exceed the given threshold, then a decision is made to transfer the system to abnormal mode. Threshold determination can be carried out using statistical methods.

Buscou-se comparar as condições de vida e a saúde mental (Transtornos Mentais Comuns - TMC) entre mulheres brancas, pardas e pretas na meia idade e velhice no contexto brasileiro. Realizou-se um estudo em ambiente virtual, descritivo, de caráter transversal, com abordagem quantitativa. Uma amostra de conveniência de 545 mulheres na meia idade e velhice do território brasileiro responderam um formulário online com uma Ficha de informações sociodemográficas e o Self-Reporting Questionnaire (SRQ-20). Foram feitas análises bivariadas (qui-quadrado de independência e teste t de Student) e uma ANOVA fatorial (p≤0,05) e foram calculados os tamanhos de efeito. Os resultados indicaram diferenças por raça/cor quanto à configuração familiar e às condições socioeconômicas, com maior proporção de pretas nos piores índices. Com relação à saúde mental, as mulheres brancas estavam mais protegidas e as pardas e as pretas solteiras apresentaram mais TMC. Os dados indicaram a complexidade envolvida na saúde mental e que o envelhecimento das mulheres pretas, pardas e brancas ocorre em contextos sociais e econômicos distintos. Uma velhice mais digna e saudável para todas as mulheres exige políticas públicas que abordem as disparidades raciais em múltiplos níveis, considerando as especificidades do racismo brasileiro.

Background: Process-Based Therapy (PBT) focuses on understanding and guiding individual change processes, diverging from group-based analyses. The approach tailor’s treatment to address individual issues, emphasizing measurable change processes for effective treatment, while recognizing that effective treatments are not constrained by a specific therapeutic orientation or strategy. The process-based assessment tool (PBAT) was developed to provide researchers and practitioners with a guide to a minimal viable set of process-based items. The PBAT is an item pool designed for intensive longitudinal clinical assessment, developed based on the PBT model. Objective: The present study aims to translate and cross-culturally adapt the PBAT into Brazilian Portuguese. Method: The cross-cultural adaptation process balances literal translation components from one language to the other and an adaptation process that takes into account the culture of the target population. The cross-cultural adaptation process occurred in four major steps: i) translation process; ii) back translation process; iii) evaluation of the semantic equivalence of the preliminary Portuguese version; and iv) pre-test. Result: The analysis of the results from the target population's evaluation was predominantly qualitative, supplemented with indicators such as the Content Validity Index (CVI) to identify potential items requiring adjustments. The results may suggest the effectiveness of the iterative refinement process, potentially increasing confidence in the accuracy and relevance of the translated PBAT for the Portuguese-speaking population. Conclusion: Future research endeavors may benefit from the translated PBAT, enabling a comprehensive exploration of within-person processes and fostering advancements in evidence-based practices.

Este artículo analiza las propiedades psicométricas, en particular la validez estructural y convergente de la Escala de Percepción de Amenaza Exogrupal (EPAE) en la versión de Carmona-Halty y Navas (2016), con 1.078 colombianos en Barranquilla, norte de Colombia, con respecto al nivel de amenaza realista, simbólica y de seguridad percibida sobre los inmigrantes procedentes de Venezuela. Los participantes fueron seleccionados mediante la técnica de ola de nieve, y sus edades oscilaban entre 18 y 78 años (M=34.6; DT=13.4), de los cuales 49% (n=523) eran hombres. Los resultados indican una alta consistencia interna de la Escala (α=0.91 y ω=0.91), y el análisis factorial confirmatorio ratificó la estructura de tres factores con adecuados índices de ajuste (CFI = 0.942, RMSEA = 0.06 y SRMSR = 0.08. NFI = 0.935, PNFI = 0.723). Los indicadores de validez (por contacto, actitudes y prejuicio hacia los inmigrantes) son coherentes con los valores de la percepción de amenaza. Se encontraron diferencias con el sexo y el nivel socioeconómico de los participantes. Se discuten los resultados de este trabajo de cara a facilitar el proceso de adaptación de los inmigrantes venezolanos en el contexto receptor.

A common problem in measurements using a set of vibration sensors in vibroacoustics is the lack of an accurate signal model on the receivers. Such uncertainty can lead to processing algorithms errors and an incorrect solution to the inverse problem. Due to a malfunction, vibration sensors data can also be bad, deteriorating the quality of measurements. In practice, the search for such anomalous sensors is a non-trivial task. In this paper, an original method related to projection algorithms is proposed for this problem. It is shown that the proposed method allows detecting anomalous sensors of various types. The method main feature is using both numerical finite element model of the object and experimental data. The efficiency of the proposed method is demonstrated in the localizing vibration sources problem. The new method can be used in other applications where the inverse problem is solved using a numerical or analytical model.
Remuneration of internal auditors in Poland
Authors: Grzesiak Lena
Published: December 2024

The study examined how internal auditors in Poland are remunerated. A content analysis of 157 job advertisements for internal auditors published by Poland-based employers and interviews with 24 internal auditors from the private and public sectors were conducted. The study found that internal auditors in Poland are offered contemporary bonuses such as a share of profits or long-term incentives, as well as bonuses determined by criteria such as the number of irregularities detected. In general, remuneration was criticised by internal auditors as unsatisfactory and falling short of their expectations. The remuneration packages used by some organisations do not adequately remunerate internal auditors for their performance and, consequently, do not incentivise them to work in line with the organisational and internal audit goals. To make them more effective and motivational, organisations should better align their structure with the expectations and needs of internal auditors. The findings of the study provide a preliminary framework for conducting research into the workplace situation of internal auditors. They can also help internal auditors who are considering a change of employer and help employers understand internal auditors’ remuneration expectations.

Low utilization of Posyandu Elderly services in Deli Serdang Regency, even though the number of elderly continues to increase. Only 5-10% of the total elderly population uses the service, influenced by inadequate service quality, the perception that Posyandu is only for the sick, and minimal understanding of its benefits. The purpose of this study is the Influence of the Role of Students, Village Heads, Cadres and Peers on the Utilization of the Elderly Love House at the Integrated Health Post. This study is quantitative cross-sectional research involving 192 elderly respondents from a population of 7,883 registered at the elderly health post in Lubuk Pakam District, using stratified random sampling and analyzed with the chi-square test at an alpha level of 0.05. This study reveals that the utilization of Rumah Kasih by the elderly is significantly influenced by the roles of cadres, village heads, and peers, while student involvement remains suboptimal. Notably, emotional and informational support from families also plays a crucial role. These findings highlight the need for innovative collaboration among stakeholders to enhance access to and utilization of Rumah Kasih, emphasizing a holistic approach to elderly care that integrates community support.
The Art of Restoration
Authors: Sandrock Kirsten
Published: December 2024

Ali Smith’s seasonal quartet partakes in the recent revival of Shakespeare’s romances by creating complex intertextual dialogues between the novels and the plays. The quartet forges a connection between the art of restoration in the romance tradition and the need for regenerative artforms at the present time. Autumn (2016) engages with The Tempest (c.1610–1611), Winter (2017) with Cymbeline (c.1609–1611), Spring (2019) with Pericles (c.1607–1608), and Summer (2020) with The Winter’s Tale (c.1609–1611). Smith’s novels form what Rita Felski calls “aesthetic attachments” to Shakespeare’s romances by connecting each of the four novels to generic motifs of the plays and turning key characters into nodes that disseminate affective and aesthetic bonds to them. Central characters negotiate the forms and function of attachments to the romances while generic ties are created through the seasonal quartet’s focus on temporality and crisis, the transformational power of art, and the quest motif as a source of future hope. Smith ties her quartet closely to Shakespeare’s romances, partly to illustrate how times of crises can be confronted with the transformative power of the arts.
A Critical Analysis of the Bugis Wedding Tradition 'Passampo Siri
Authors: Jamal Ridwan , Mitra Asandi
Published: December 2024

This paper examines the Passampo siri’ tradition (marriage of disgrace) in the Bugis community through paradigmatic analysis using the framework of Critical Theory. The research method used is a literature study to collect data from relevant literature sources. The data were analyzed qualitatively with a paradigmatic approach to achieve contextual and in-depth meaning related to the philosophical background of Passampo Siri’ and its implications for his abolition discourse. The results of the analysis show that Passampo siri’ is actually a socio-cultural entity born from the habitus of the Bugis people towards the concept of self-esteem (siri') as a core value. Removing them without a contextual understanding can threaten the integrity of the values that have been upheld and closely guarded so far. Therefore, this case reminds us of the importance of reflective attitudes and multidimensional analysis before deciding to "break" a tradition that is considered purely irrational. This research seeks to integrate epistemological reflections from critical theory in understanding the Passampo siri’, highlighting how power structures, ideologies, and social norms shape and influence those cultural practices. This study emphasizes that the abolition discourse must consider the historical and social context behind this tradition. The results of this study provide insight that cultural reform requires an approach that respects the complexity and richness of local values, while opening up a space for constructive critical dialogue.
Development of Students’ Cognitive Competencies in Digital Education: to the Problems of Consequences and Conditions of Education Digitalization Productivity
Authors: Kasymova Gulzhayna , Arpenteva Mariyam
Published: December 2024

Today, the issue of the consequences and conditions for the education digitalization productivity is one of the most pressing and complex issues, despite the insufficient degree of study. Modern education faces with the need to implement a competency-based approach, which involves redesigning educational programs making an emphasis on key competencies. They contain cognitive skills that form students’ general cognitive competence, including critical thinking, analysis, information synthesis and problem solving. Digitalizing education in higher learning institutions opens up new opportunities for developing these skills, making the educational process conscious, structured and effective. However, for the successful implementation of digital technologies, one must meet a number of conditions. The most important of them are availability of modern technical infrastructure, training teachers to use digital tools, adapting methodological approaches, ensuring an effective assessment and monitoring system. These conditions ensure not only the high-quality use of technologies, but also their integration into the educational process, which contributes to a deeper and more comprehensive development of students’ cognitive competencies. Thus, digitalization can significantly increase the education productivity if people meet all the necessary conditions.
