High-strength concrete (HSC) and self-compacting high-strength concrete (SCHSC) are increasingly used in modern construction. This study investigates the effect of different construction joint positions on their mechanical properties and structural behavior. Understanding the influence of joint orientation and location is essential for ensuring the safety and durability of structural elements. Therefore, studying construction...

The Bay of Bengal (BoB) is a global hub for marine elasmobranchs, particularly sharks and rays. These apex predators maintain and structure the balanced marine ecosystem and food webs. Marine elasmobranchs in Bangladesh are under-researched and under-managed, and face threats such as habitat degradation, global warming, pollution, illegal fishing, and overexploitation. This study aimed to evaluate the stock status of marine el...

An ultrasensitive, selective, rapid, and cost-effective spectrofluorimetric approach is established and validated to quantify the ophthalmic fluoroquinolone antibiotic, besifloxacin (BN), in its ophthalmic preparations and artificial aqueous humor. Unlike previously reported methods that require costly fluorogenic derivatization reagents, lengthy analytical procedures, or expensive instrumentation, the proposed approach offers...
