Battery Energy Storage Optimization for Enabling Black Start in Offshore Wind Farms
Abstract: The transition toward power systems dominated by renewable energy sources (RES) introduces significant challenges to the provision of black start services. Black start units are essential for restoring power following a system-wide outage; however, the gradual retirement of conventional generation reduces the availability of such resources, potentially compromising grid resilience. Offshore wind farms (OWFs) are increasingly considered as viable alternatives for black start support. Nevertheless, their inherent variability and intermittent …

Effectiveness of Habb-e-Suranjan and Roghan-e-Farfiyun in the Management of Waja-ul-Rukba (Knee Pain): A Review
Abstract: Introduction: Knee osteoarthritis is a painful condition that represents the degeneration of the cartilage and osteophyte formation in the knee joint, which affects millions of people worldwide. According to the Unani claimed text, accumulation of “madda” (substance) in joints, which is neither absorbed nor expelled, is due to the absence of Quawwat-e-Jazibah (power of absorption) and Quawwat-e-dafia (power of expulsion). Unani medicine presents a promising approach for managing knee osteoarthritis …

Pharmacophore mapping, 3D QSAR, docking, and ADME prediction studies of novel Benzothiazinone derivatives
Abstract: Background Tuberculosis is a major public health concern worldwide which is caused by Mycobacterium tuberculosis. DprE1 (Decaprenyl Phosphoryl Ribose 2’- Epimerase) is the most challenging target for development of novel anti- tubercular agents because it is a small protein and located into cytoplasmic membrane. So, novel anti-TB drugs did not bound effectively with it. DprE1 catalyzes the oxidation of the 2’ hydroxyl group of DPR (Decaprenyl Phosphoryl D- Ribose) …
