Comparative analysis of direct coupling and MPPT control in standalone PV systems for solar energy optimization to meet sustainable building energy demands.

Solar energy, a prominent renewable source, has reached an installed capacity of 71.78 GW in India. This research explored the load demands of the computer center at an engineering college in Tanjore, Tamil Nadu, India.

Effect of the Piezoelectric Device on Intraoperative Hemorrhage Control and Quality of Life after Endodontic Microsurgery: A Randomized Clinical Study.

Introduction: The purpose of this study was to evaluate the effect of the piezoelectric device on intraoperative hemorrhage control during surgery and the quality of life of patients after endodontic microsurgery.

Methods: A total of 40 patients were randomly divided into the piezo group (n = 20) and the control group (n = 20). In the piezo group, after flap reflection, bone cutting, granulation tissue removal, and root-end resection were performed using the piezoelectric surgical device and surgical carbide burs, and curettes were used in the control group.
