Aerodynamic and surface pressure characteristics of quasi two-dimensional wings featuring leading-edge flags: An experimental and statistical approach

The present study explores a passive flow control technique utilizing leading-edge flags (with and without serrations) over the airfoil to improve the performance of the airfoil. These flags are attached to the leading-edge of the airfoil that oscillates naturally in response to...

Transformational leadership and organizational culture as predictors of employee resilience: the moderating role of AI control in IT firms

Purpose This study aims to investigate the relationship between employee resilience in the IT industry and the effects of transformational leadership and organizational culture, as well as the moderating effect of AI control systems in the relationships mentioned above. The objec...

Multicomponent Synthesis of Coumarin‐Tethered Triazoles and β‐Enaminones Under Metal‐Free Conditions

ABSTRACT A facile, divergent, multicomponent strategy for the synthesis of coumarin‐tethered β‐enaminones and triazole derivatives under environmentally benign, metal‐free conditions has been developed. This one‐pot, three‐component reaction from readily available starting materi...

Ventilation performance and optimization of building-integrated wind catchers in dense urban canyons with adjacent window openings

Natural ventilation in dense urban street canyons is often constrained by low wind speeds, flow recirculation, and turbulent air movement, resulting in poor indoor air quality and thermal comfort. Wind catchers offer a passive ventilation strategy by capturing higher-altitude win...

Deep Red Emissive Asymmetric D-A-D′ D\text{-}A\text{-}D^\prime$ AIEgens Exhibiting Substituent-Dependent Tunable Emission and Optical Waveguiding

Abstract A series of asymmetric D-A-D′ aggregation-induced emission compounds (AIEgens) were synthesized by linking triphenylamine (TPA, D) and benzofuran (BF, D′) donors with a malononitrile (A) acceptor. Their structures and the influence of various substituents on solid-state...

Market efficiency and sectoral heterogeneity in the BSE 100 ESG Index: a time-series and Fama–French factor approach

Purpose This study examines the weak-form market efficiency, factor-driven return behaviour and sectoral financial performance of the BSE 100 ESG Index in India. Design/methodology/approach The study adopts a quantitative research design using secondary data. Monthly-closing valu...
