The thesis presents a systematic study of the Mpemba effect in a colloidal system with a micron-sized particle diffusing in a water bath. While the Mpemba effect, where a system's thermal relaxation time is a non-monotonic function of the initial temperature, has been observed in water since Aristotle's era, the underlying mechanism of the effect is still unknown. Recent studies indicate that the effect is not limited to water and has been studied both experimentally and numerically in a wide variety of systems. By carefully designing a double-well potential using feedback-based optical tweezers, the author demonstrates that an initially hot system can sometimes cool faster than an initially warm system. The author also presents the first observation in any system of another counterintuitive effect-the inverse Mpemba effect-where the colder of the two samples reaches the thermal equilibrium at a hot temperature first. The results for both the observations agree with theoretical predictions based on the Fokker-Planck equation. The experiments reveal that, for carefully chosen conditions, a strong version of both of the effects are observed where a system can relax to the bath temperature exponentially faster than under typical conditions.

The consumption of energy in developed countries is very high as compared to developing countries. It is the need to use of energy very carefully for getting highest yield in agricultural production system. Sugarcane is an important commercial crop and it cultivated in about 75 countries. The leading countries are Brazil, India, China, Thailand and Pakistan in the production of sugarcane. Sugarcane belongs to the bamboo family of plants and is indigenous to India. It is the main source of sugar, gur and khandsari. About two thirds of the total sugarcane produced in India is consumed for making gur and khandsari and only one-third of it goes to sugar factories.

All humans have an identity in life. The size, shape, and pattern of human bites are thought to be specific to an individual. The teeth when used as an arsenal may leave information about the identity of the biter. The forensic analysis of such human bite marks can be helpful in winning over the perpetrators of crime and providing justice to the victim. This book outlines the historical overview of human bite marks, discusses the key concepts on human bite marks evidence collection and takes you through the scientific analytical techniques and methodologies involved in case management. If you want to bite forensic dentistry but doesn¿t know how this book is for you.
