In this study, the reactive dyeability of 100% cotton, acrylic-cotton (Co)/acrylic, and Ecocell/acrylic blend woven fabrics in a single bath was examined. The results were assessed in terms of washing fastness, hydrophilicity values, and color fastness. Additionally, the effect of using cotton and Ecocell fibers together with acrylic fibers on the physical properties of the fabrics was investigated, and the test results were analyzed. Experiments were conducted on satin weave and plain weave fabrics with two different yarn counts. As a result, no negative effect was observed on the fastness values when reactive dyeing was performed in a single bath on 100% cotton, Ecocell/acrylic, and cotton/acrylic blend woven fabrics, although differences were observed in K/S values.

The need for renewable and sustainable resources is increasing like an avalanche every day in order to take measures against the decreasing oil resources on earth and the crises that will be experienced in the related industries. Lignin, a natural biopolymer, is abundant in terms of renewable resources. Nowadays, very intensive efforts are being made to evaluate the wastes of biological resources and to produce upcycled materials. In this study, we synthesised polyurethane by polycondensation reaction by obtaining lignin from corn cob wastes and chitosan from shrimp shells. The effects of temperature, pressure and time on the synthesis process were investigated and the optimum process conditions were determined. It was concluded that the production efficiency increased with the effect of catalyst and the water output rate improved accordingly. It is stated that the adhesion process of polyurethane with metal cans is compatible with the adhesion process of polyurethane to be used in the filter sector.

Authors: Harmandar Nil , Altınoluk Hayriye Serra
Published: January 2025

Heart-lung machines used in open heart surgeries pump the necessary blood with two different types of pumps integrated into them. These pumps are roller or centrifugal pumps. While roller pumps are preferred more frequently in cardiac surgeries due to their ease of use and relatively low cost, centrifugal pumps are preferred in cases where long-term mechanical cardiac support or long-term oxygenation is required. Centrifugal pumps are suitable for longer-term use due to their advantage of causing less damage to the shaped elements of the heart (thrombocytes, leukocytes and erythrocytes) compared to roller pumps. Other flow types of heart-lung machines are pulsatile and non-pulsatile flows which may influence the side-effects of these machines on human body. While non-pulsatile blood flow pumps blood into the body continuously at a constant pressure, pulsatile blood flow pumps blood intermittently, imitating the heart's beating pattern. Therefore, pulsatile blood flow is more physiological and has many benefits over non-pulsatile flow, such as reducing inflammation that may occur in the body and thus reducing the side effects of the heart-lung machine. Although there are many studies on the pulsatile flow using roller pumps, there is no device in daily use that will provide an adjustable pulsatile flow using a centrifugal pump. There are very few experimental studies on centrifugal pumps providing pulsatile flow in which the frequency and flow rate of the pulsatile flow was often kept constant. Currently, no device that can adjust the desired frequency and flow rate has yet entered the routine use. Thus, the aim of this project is to design a simple prototype of such a centrifugal blood pump that will provide pulsatile blood flow which will be adjusted in terms of frequency and flow rate.

Authors: Pilla-Castrillón Steven Paúl , Bombón-Pozo Caroll Alexandra
Published: January 2025

Introducción: Las enfermedades cardiovasculares son la principal causa de muerte y el síndrome coronario, causado por la ruptura de una placa aterosclerótica, es una de sus formas más graves. La angioplastia coronaria (PCI) ha sido la opción preferida para restablecer el flujo sanguíneo en infartos. En otras ocasiones, los pacientes son derivados para injerto de derivación arterial coronaria (CABG) por isquemia persistente o anatomía coronaria de alto riesgo.
Métodos: Se realizó una revisión bibliográfica utilizando la metodología PRISMA acerca de estudios recientes que comparan técnicas de revascularización coronaria. La búsqueda se llevó a cabo en bases de datos como PubMed, Google Scholar y The New England Journal of Medicine. De 222 artículos, se seleccionaron 12 que cumplieron con los criterios predefinidos para su análisis.
Resultados: En la enfermedad de la arteria coronaria izquierda de baja a moderada complejidad, PCI y CABG muestran resultados similares a corto plazo en términos de mortalidad, infarto agudo de miocardio y accidente cerebrovascular. La PCI ofrece beneficios a corto plazo (entre 30 días y el primer año), aunque se asocia con una mayor necesidad de revascularización a cinco años. En contraste, la CABG reduce significativamente los eventos adversos mayores, la necesidad de revascularización y mejora la supervivencia a largo plazo, siendo especialmente beneficiosa en enfermedad coronaria multivaso y altos puntajes Syntax.
Conclusiones: La PCI con stent continúa siendo una opción viable en pacientes con lesiones coronarias de bajo riesgo, mientras que CABG es superior en lesiones complejas y comorbilidades como diabetes o enfermedad renal crónica.

Published: January 2025

This study examines the performance of asphalt concrete mixtures using foamed bitumen derived from extracted Buton natural asphalt (Asbuton) in comparison to conventional penetration asphalt (Pen 60/70). The research focuses on evaluating key parameters such as aggregate properties, Marshall stability, indirect tensile strength, and other mix characteristics, benchmarked against Indonesian national standards. Asbuton, known for its high viscosity and resistance to extreme conditions, offers an alternative binder for sustainable road infrastructure development. The results demonstrate that foamed Asbuton significantly outperforms Pen 60/70 in critical metrics. Foamed Asbuton achieved higher stability (2440.8 kg) and a superior tensile strength ratio (92.78%), reflecting its robustness under heavy loads and resistance to moisture-induced damage. In contrast, Pen 60/70 exhibited reduced stability and rigidity when subjected to the foaming process. The enhanced performance of foamed Asbuton is attributed to its dense structure and the benefits of the foaming process, which improves aggregate coating and binder distribution at lower mixing temperatures. This study highlights the potential of foamed bitumen technology, particularly when paired with high-performance binders like Asbuton, to improve the durability and sustainability of road infrastructure. Foamed Asbuton emerges as a promising material for high-stress applications and extreme environmental conditions.

Effect of Classroom Arrangement on Fire Evacuation Scenarios in Educational Buildings
Authors: Yaman Muammer
Published: January 2025

Fires in educational buildings cause great loss of life and property, but also negatively affect the spiritual and psychological development of students. It is necessary to eliminate fire risks and create safe learning environments. For this purpose, national and international fire safety regulations and application guidelines are of great importance. However, thanks to the developing technological possibilities, buildings should be analyzed with performance-based fire safety precautions, and safe evacuation conditions should be created. In this study, it is aimed to create a safe educational environment by determining the effectiveness of the relevant classroom layout arrangements in the creation of fire safety precautions in the classrooms in educational buildings. The effects of classroom layout arrangements on fire evacuation time were discussed by considering a secondary school building located in Turkiye. Classroom layout arrangements are investigated in four different formats: traditional rows and columns arrangement, cluster arrangement, U-shaped arrangement, and stadium arrangement. In the studies, the results of the total evacuation time of the class (s), the escape door flow rate (pers/s), and the number of occupants staying in the room depending on the time were evaluated. As a result of the study, it was determined that the fastest evacuation time was the traditional rows and columns arrangement. In addition, solution suggestions are presented for the removal of congestion during fire evacuation in different classroom layout arrangements. Fire safety should be transferred to architectural design and spatial organization as an important component in creating a safe learning environment in educational buildings.

Published: January 2025

With small and medium-sized enterprises being vital contributors to economic growth, understanding the factors influencing their performance is crucial. The purpose of the study was to empower Ghanaian small and medium-sized enterprises with the knowledge and tools needed to effectively leverage innovation and marketing intelligence, driving sustainable growth and competitiveness in the evolving business landscape. Utilising a quantitative approach, 200 respondents were surveyed using random sampling. The study utilised dynamic capabilities to substantiate and explain the social phenomena analysed using the statistical package for Social Sciences and Structural Equation Modelling techniques. The results indicate that small and medium-sized enterprises stand to benefit from enhancing marketing, product, organisational, and process innovation to bolster their performance in the competitive landscape. Despite the acknowledged importance of innovation in small and medium-sized enterprises, empirical studies focusing on specific dimensions and their impact on performance are limited. This study fills this gap by identifying and analysing the relationships between innovation dimensions, market intelligence, and small and medium-sized enterprises performance. By providing actionable insights derived from empirical analysis, the research offers valuable guidance for small and medium-sized enterprises stakeholders, aiding strategic decision-making and competitiveness enhancement. Moreover, the study contributes to theoretical development by enriching understanding of how innovation and marketing intelligence drive small and medium-sized enterprises performance. The practical implications of the findings are significant, offering small and medium-sized enterprises a roadmap for leveraging innovation and market intelligence to thrive in dynamic business environments. Overall, this study enhances scholarly knowledge of the factors influencing small and medium-sized enterprises performance and provides practical guidance for small and medium-sized enterprises operators, policymakers, and other stakeholders invested in the success of small and medium-sized enterprises in Ghana
Financial behaviour in a cultural context: Cross-countries analysis of savings and consumption
Authors: Shkvarchuk Lyudmyla , Slav'yuk Rostyslav
Published: January 2025

This study investigated how certain aspects of national culture affect saving and consumption behaviours. The study examined the correlation between gross saving, consumption, and economic development for 38 countries, including both developed and developing ones, from different continents, with data from 1996 to 2021. The cross-countries correlation indicators differed quite a lot in 1996-2008 and somewhat levelled later in 2009-2021. The growth of financial literacy and financial inclusion of the economic agents explained such changes. The findings suggest that countries exhibiting a strong relationship between income and savings are more receptive to the tools of monetary policy. In contrast, the economies expressing a strong relationship between income and consumption are more susceptible to the tools of fiscal policy. Therefore, high correlation scores are more desirable. Cluster analysis was employed to define groups of comparable countries for evaluation of national aspects of saving and consumption behaviour. Single membership in 2- and 3-clusters were observed, but the list of countries in these clusters differed across the years. The pronounced homogeneity of the clusters indicated the absence of significant national differences in the saving and consumption behaviour of economic agents according to the selected factors of comparison. This allows using the same instruments of regulation and stabilisation of the economy in the countries that are the closest neighbours in the cluster. The study stressed the significance of including national cultural elements in the analysis of financial behaviour and the formulation of macroeconomic policy. Awareness of these cultural differences enables policymakers to adapt their strategies more effectively to enhance economic growth and stability

Accurate and Precise Quantification of Arsenic and Selenium in Water and Biological Samples Through the Removal of Doubly Charged Rare Earth Element Interferences by ICP-MS
Authors: Colman Benjamin P. , White Dylan T. , Young Matt , Feijó de Lima Rafael
Published: January 2025

This month’s column evaluates the capability of inductively coupled plasma–mass spectrometry (ICP-MS) to reduce the impact of doubly charged rare-earth element (REE) interferences on the quantitation of the metalloids, arsenic (As), and selenium (Se) in water and biological matrices. It compares the performance of a number of different interference reduction techniques, including correction equations, and collision/reaction cells (CRC), using various ion-molecule collisional and reaction mechanisms. To identify an optimal method of removal, the authors first assessed the magnitude of interference by individual REEs before comparing the efficacy of their removal with helium as a collision gas and hydrogen, ammonia, and oxygen as reaction gases using different “on mass” and “mass shift” analytical scenarios. Their conclusion was that the only modes to consistently remove REE interferences used oxygen with mass shift, which had better accuracy and lower detection limits for both arsenic and selenium.

Authors: Flores Ana Cecilia
Published: January 2025

La responsabilidad social ha tomado relevancia en el sector empresarial como estrategia para crear una ventaja competitiva. En México, las empresas comprometidas con el mejoramiento económico, de la sociedad y el medio ambiente son candidatas a obtener el distintivo de empresa socialmente responsable, el cual agrega valor a la marca. Una de las metas de las empresas es crear valor para los accionistas, incrementando el valor de las acciones, sin embargo, el precio de las acciones en el mercado varía en función de ciertos factores, como la preferencia de los inversionistas hacia las empresas que ofrecen mayores dividendos, la competencia existente con el mercado de bonos, el prestigio de la empresa, la preferencia de los consumidores, entre otros. El objetivo del presente estudio es indagar si el distintivo de responsabilidad social agrega valor a las empresas que cotizan en la Bolsa Mexicana de Valores, considerando la razón de precio de mercado de una acción a su valor en libros. Se empleó un enfoque cuantitativo, mediante una prueba U de Mann-Whitney, para determinar la diferencia estadística entre empresas reconocidas como socialmente responsables y empresas que no cuentan con el distintivo de responsabilidad social, en función a la razón precio/libros durante el periodo 2023. Como resultado de la investigación se determinó que no existe una diferencia estadísticamente significativa entre los dos grupos de empresas, por lo que contar con el distintivo de responsabilidad social no influye de manera significativa en el precio de mercado de las acciones.

Published: January 2025

Al-Jam’iyatul Washliyah is one of the Islamic organizations in Indonesia. The word Al-Jam’iyatul Washliyah comes from Arabic which means a gathering or association that connects. An Islamic group involved in community service, education, and da'wah (spiritual guidance), the Al-Wasliyah organization is the focus of this research. Qualitative methods, including in-depth interviews, observation, and documentation, make up the research strategy. The data was subjected to thematic analysis to reveal recurring themes regarding implementing Islamic leadership and management concepts. The results of the study show that Al-Wasliyah consistently applies Islamic values in its organizational activities, such as shura (deliberation), amanah (trust), justice, and management efficiency. Leadership in Al-Wasliyah is based on Islamic principles, including the characteristics of Siddiq (honest), tabligh (communicative), fathanah (intelligent), and amanah (trustworthy). Based on Islamic teachings, organizational leaders act as role models, motivators, and decision-makers. However, this study also found challenges, such as the lack of consistency in applying Islamic management principles at the branch level, limited competent human resources, and minimal use of technology to support organizational activities. The main supporting factors for organizational success include strong Islamic values, extensive networks, and the spirit of Islamic brotherhood. This study concludes that the application of Islamic management and leadership in Al-Wasliyah has a positive impact on organizational performance, although efforts are still needed to modernize and strengthen in several aspects. Recommendations include increasing leaders' capacity, strengthening organizational structures, and utilizing digital technology to support more effective organizational management.

This study aims to examine the implementation of Islamic management and leadership in the Himpunan Mahasiswa Islam (HMI) organization in Padangsidimpuan, focusing on organizational culture, leadership style, and change management. The research employs a qualitative approach through in-depth interviews, participant observation, and document study to collect data from the management, active members, and alumni. The findings show that HMI's organizational culture, based on Islamic values such as honesty, trustworthiness, consultation (musyawarah), and ukhuwah Islamiyah, plays a significant role in the formation of cadres with Islamic character. The consultation-based leadership style (syura) has proven effective in increasing member involvement and collective decision-making, although challenges such as apathy and differing viewpoints can slow down the process. Additionally, HMI's organizational management demonstrates good adaptability in facing changes through mechanisms such as monthly evaluation meetings and cadre training. This study concludes that the interaction between organizational culture, leadership style, and adaptive management is key to HMI's success in producing competent cadres who contribute to society.
