Focusing on biodiesel as a sustainable alternative to petroleum diesel, this dissertation explores the production from non-edible oils like Used Cooking Oil, Cottonseed oil, Jatropha oil, and Neem oil. Employing a two-step transesterification process, it highlights the effectiveness of acid-alkaline catalysis over enzyme-catalyzed methods, achieving higher biodiesel yields. The study addresses challenges in enzyme use, such as cost and efficiency, while demonstrating the potential of these renewable resources for biodiesel production.

Focusing on the critical phase of adolescence, this study emphasizes the need for effective adjustment to environmental demands. It addresses the lack of a standardized adjustment inventory in Telugu, aiming to develop the Adolescent Adjustment Inventory (AAI) in both English and Telugu. The AAI encompasses five key adjustment contexts: home, health, academic, social, and emotional. The development process included item analysis and expert feedback, resulting in 332 items that were carefully translated and validated for linguistic equivalence.
