Harmonic Mitigation in Shunt Active Power Filter Regulation Approaches with Synchronous Reference Frame: An Extensive Analysis
Abstract: The Shunt Active Power Filter (SAPF) is discussed in this work as a means of removing line-side current harmonics. The Voltage Source Inverter (VSI) topology serves as the foundation for the Active Power Filter. It resolves the power system's harmonic current issue. Additionally, it balances the load on three phases and compensates for reactive power (if load is unbalanced). After measuring load current, it switches to the dq0 coordinate system. …

Enhancement of ATC using UPFC under Deregulated Environment
Abstract: Available transfer capability is the most important factor for the identification of power transfer from gencos to discos. In a deregulated power system, power producer and customer share a common transmission network for wheeling of the electric power. This may cause violation of line flow, voltage and stability limits and thereby undermine the security limit [1]. To improve the available transfer capability of the system FACTS controllers are used. UPFC …

Hematopoietic stem progenitor cells reduce the proliferation of Tregs via regulation of IL-12/STAT4 signaling during chronic stress
Abstract: Abstract. Physical or psychological chronic stress mediates the impaired immune response by inducing the proliferation of regulatory T cells (Tregs). Our recent studies showed that hematopoietic stem progenitor cells (HSPCs) significantly modulated the immune system. HSPCs prevented stress-induced lymphocyte apoptosis, exerting a protective effect in chronic stress-induced immune responses. Thus, whether HSPCs could prevent the proliferation of Tregs in conditions of chronic stress was assessed in the present study. Injection …

A Single Case Study on Ayurvedic Therapeutic Management for Increasing Growth Hormone in Pre-Pubertal Girl
Abstract: Human growth hormone, commonly referred to as HGH and somatotropin, is a naturally occurring hormone released by the pituitary gland that promotes growth in children by acting on various body regions. The pituitary gland produces the polypeptide hormone known as human growth hormone (hGH), or somatotropin, which is made up of 191 amino acids. A lack of human growth hormone (hGH) in children can result in growth failure, low stature …

Experimental Study on the Impact of Polymer (PAM) in Enhancing Oil Recovery in Upper Assam Basin Oil fields
Abstract: The Upper Assam Basin, one of India’s most mature and extensively exploited hydrocarbon provinces, is experiencing declining oil production due to reservoir depletion and unfavorable crude oil–brine–rock (COBR) interactions. In this context, alkali–polymer (AP) flooding has emerged as a promising chemical enhanced oil recovery (EOR) strategy. AP flooding reduces interfacial tension (IFT) through in-situ surfactant generation by alkali and improves sweep efficiency via polymer-based mobility control, typically using polyacrylamide (PAM). …
