Restructuring of power market not only introduces competition， but also brings complexity which increases overloading of Transmission Lines (TL). To obliviate this complexity， this paper aims to mitigate the overloading and estimate the optimal location of Static Synchronous Compensator (STATCOm) by reducing congestion for a deregulated power system. The proposed method is based on the use of Locational marginal Price (LmP) difference technique and congestion cost. LmPs are obtained as a by-product of Optimal Power Flow (OPF)， whereas Congestion Cost (CC) is a function of difference in LmP and power flows. An endeavor is justified by reducing the CCand solution space which can identify the TLs more suitable for placement of STATCOm. Importantly， total real power loss， reactive power loss and total CCare the three main objective functions in this optimization process. The process is implemented by developing an IEEE-69 bus test system which verifies and validates the effectiveness of proposed optimization technique. Additionally， a comparative analysis is enumerated by implementing two optimization techniques: Flower Pollination Algorithm (FPA) and Particle Swarm Optimization (PSO). The comparative analysis is sufficient to demonstrate the superiority of FPA technique over PSO technique in estimating an optimal placement of a STATCOm. The results from the load-flow analysis illustrate the reduction in CC， total real and reactive power loss using FPA technique over PSO technique. Overall， satisfactory results are obtained without using complex calculations which verify the effectiveness of optimization techniques.

Curry leaves, scientifically termed murraya koenigii, are renowned in South Asian cuisine for their flavor enhancement and potential health benefits, including antioxidative, anti-inflammatory, and antidiabetic properties. This study aimed to evaluate the impact of thermal processing methods on curry leaves by analysing Total Phenolic Content (TPC), Total Flavonoid Content (TFC), antioxidant activity, and metabolizing enzyme inhibition. Fresh curry leaves were subjected to thermal treatments: Oven-dried at 60˚C and Air-dried at 25˚C for 2 weeks. Extracts were prepared using Ethanol and water solvents. Results indicated that Air-dried leaves exhibited significantly higher TPC (5132.65 mg GAE/100 g) and TFC (243.13 mg CE/100 g) compared to Fresh and Oven-dried leaves. Antioxidant assays show that oven-dried curry leaves at 60˚C displayed higher results in NORS, FRAP, and TEAC assays compared to Fresh and Air-dried leaves. Ethanol extracts showed better extraction of bioactive compounds than aqueous extracts. moreover, Lipase inhibition activity was notably high, indicating potential health benefits. This study provides valuable insights into the effects of processing methods on curry leaf extracts, emphasizing the importance of solvent selection for optimal extraction of bioactive compounds.
