(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND, 2026) Kızanlıklı, Mustafa Murat; Çıkı, Kartal Doğukan; Tanrıverdi, Haluk
The main aim of this research is to examine the effects of Turkish TV dramas on Kyrgyz audiences and how the perception of Türkiye is shaped through TV dramas. For the purpose of the research, a survey was conducted with 310 Kyrgyz residents who watch Turkish TV dramas. The data was analyzed using structural equation modeling and the relationships between participants’ knowledge, perceived experience, perceived image of Türkiye, and behavioral intentions were tested, and a conceptual model was developed to help explain the behavioral intentions of TV drama audiences. The results of the study demonstrated that Turkish TV dramas created a positive perception of Türkiye among Kyrgyz audiences and this perception had a significant impact on travel intention, willingness to visit locations of TV dramas and intention to purchase Turkish products. This research provides important insights into the role of Turkish TV dramas on tourism, marketing and consumer behavior by exploring the effects of Turkish TV dramas on audiences in detail. The research provides guidelines for applications such as creating TV dramas-based tourism routes, optimizing product placement strategies, and developing personalized promotional content on digital platforms.
Economically Advantageous Two-Stage Heat Exchanger Configuration for High-Temperature Exhaust Heat Management in Multi-Generation System Utilized in Heat-Driven Humidification-Dehumidification Desalination Unit and sCO2 Cycle Leveraging Metaheuristic Bat Algorithm
(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2026) Li, Yonghui; Basem, Ali; Balla, Hyder H. Abed; Khlifi, Mohamed Arbi; Zhang, Haibo; Abu-Zinadah, Hanaa; Bu Sinnah, Zainab Ali; Norberdiyeva, Muyassar; Fouad, Yasser; Mahariq, Ibrahim
This study proposes value-oriented thermal management in a sustainable biomass-based freshwater and hydrogen production system integrating a humidification–dehumidification (HDH) desalination unit with a supercritical CO₂ Brayton cycle and PEM water electrolysis, driven by rice straw biomass. A comprehensive thermodynamic model evaluates system performance, with particular emphasis on freshwater generation under varying operating conditions, including gas turbine pressure ratio, turbine inlet temperature, and biomass feed rate. High-temperature exhaust gases from the gas turbine transfer their thermal energy through two heat exchangers as a cost-effective approach. The first heat exchanger supplies heat to drive the supercritical CO₂ (sCO₂) Brayton cycle, generating additional power. Within the sCO₂ cycle, an internal heat exchanger provides heated air for residential space-heating applications. The second heat exchanger recovers residual exhaust heat to drive the HDH desalination cycle, producing freshwater. The system simultaneously delivers electricity, freshwater, hot air, hydrogen, and oxygen. Performance analyses indicate that increasing the gas turbine pressure ratio enhances electrical power and hydrogen production while reducing thermal outputs such as freshwater and hot air. Conversely, higher turbine inlet temperatures favor freshwater and hot air generation. Results show that freshwater production increases significantly with higher turbine inlet temperature and biomass feed rate, reaching up to 216.8 L/h and 235.3 L/h, while higher pressure ratios reduce water yield due to enhanced energy extraction in the power cycle. A metaheuristic bat algorithm is used for multi-objective optimization to maximize freshwater and hydrogen production while improving overall system efficiency. An optimal configuration achieves high freshwater yield, considerable hydrogen generation, and efficiency exceeding 80%.
Molecular Dynamics Investigation of Structural and Thermophysical Properties of Capric Acid–Silica Nanocomposites Under Varying Initial Pressures
(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2026) Singh, Narinderjit Singh Sawaran; Idan, Mahmoud Fadhel; Kareem, Muthanna K.; Mahariq, Ibrahim; Hussein, Muntadher Abed; Alrawashdeh, Albara Ibrahim; Sabri, Laith S.; Taner, Mahmut; Salahshour, Soheil
The initial thermodynamic condition can influence the organizational behavior of molecules and the energy transportation in nanocomposites of phase change materials, whereas the pressure dependence property behavior of fatty acid-silica is not fully known on the molecular scale. In this work, MD simulations were performed to study the effects of the initial pressure of the first phase range of 1–3 bar, which impacts structural and thermo-physical properties for a capric acid-silica nanocomposite. The simulated system for the second-phase run was divided into two parts: first, an equilibration stage to maintain the system temperature at 300 K; second, a production stage to measure changes in local number density, atom velocity, temperature, heat flux, thermal conductivity, charging time, and discharging time. The consistency during thermal equilibration verified that the system reached a stable state, followed by evaluation. The maximum local number density at the heat reservoir increased from 0.0338 atoms/ to 0.0323 atoms/ under higher initial pressures, with a decrease in maximum velocities and temperatures from 0.0010 to 0.0008 Å/fs and 328.26 to 318.22 K. Concomitant decreases of thermal flux and thermal conductivity can also be observed during this period. The heat flux decreased from 8.10 to 7.79 W/m, and thermal conductivity from 0.29 to 0.23 W/mK, while the charge time slightly increased from 4.68 to 4.88 ns and the discharge time was almost invariant, close to the mean value of 6.19 ns, with slight variance at different initial pressures. In addition, this initial pressure can affect local molecular mobility and local structural properties. The research provides evidence of the influence of initial thermodynamic pressure on structural features, dynamics, and transport of the nanocomposite from a molecular view.
Mitigating Operational Costs for Circular Supply Chain by Leveraging Big Data Analytics Driven-Dynamic Capabilities: Insights and Implications for the Industry
(ISTANBUL UNIV, SCH BUSINESS, ISTANBUL UNIV, SCH BUSINESS, ISTANBUL 34322, Turkiye, 2026) Uyar, Metin
The circular supply chain plays a critical role in minimizing operational costs and enhancing eco-efficiency by strategically aligning diverse organizational processes. To effectively generate these circular supply chains, it is vital to comprehend the dynamic capabilities shaped by big data analytics within a comprehensive framework. In this context, the capabilities driven by big data analytics are analyzed by using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method, which assists in identifying intricate cause-and-effect relationships among the various factors affecting the supply chain. This method enables a nuanced understanding of how different elements interact and influence one another. Moreover, based on their level of influence, the Interpretive Structural Modeling (ISM) method is employed to organize these capabilities hierarchically. The resulting hierarchical model categorizes the factors into four distinct levels. The results reveal a four-level hierarchy in which the Sensing DC (BDDC3) and Seizing DC (BDDC13, BDDC11) at Level IV act as core capabilities for the entire system. The findings specifically demonstrate that prioritizing, sensing, and other capabilities are the primary drivers of operational cost optimization in successful resource reconfiguration and circular operations. Organizations can better navigate the complexities of circular supply chains by establishing this structured approach. It ultimately leads to improved sustainability outcomes and enhanced economic performance.
Words That Work: Multilingual Repertoires and Survival-Oriented Linguistic Capital Among Interstate Migrant Construction Workers in An Informal Labour Economy
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND, 2026) Anser, Muhammad Khalid; Kariveliparambil Mohammed Ashraf, Ashifa; Munuswamy, Jothi; Saravanan, K.; Babu, Jobi
Labour migration has transformed many workplaces into multilingual environments; however, research has largely focused on formal organisational settings and language barriers rather than on how workers actively navigate linguistic diversity in informal labour economies. This study explores how interstate migrant construction workers in Kerala develop and mobilise multilingual repertoires in Malayalam-dominant workplaces. Data were generated through indepth interviews with 18 migrant construction workers and were analysed using reflexive thematic analysis. Five themes were identified: linguistic bricolage as daily survival, language as workplace capital, language brokerage and unequal access, gendered linguistic experiences, and language, belonging, and shifting insider/outsider positions. The findings show that workers rely on flexible combinations of language fragments, gestures, observation, visual resources, and peer support to navigate workplace communication and everyday life. Language has emerged as both a communicative resource and a form of workplace capital, shaping access to information, employment continuity, and participation. The findings suggest that multilingual repertoires operate as survival-oriented linguistic capital under conditions of precarity and limited institutional language support. The study contributes to multilingualism scholarship by advancing the understanding of language, labour, and belonging in informal migrant labour economies of the Global South.
