Antioxidants and Oral Health

The oral cavity is ubiquitous of various bacteria due to steady assaults of various food substances, soft drinks, alcohol, tobacco products etc. Antioxidants are substances that inhibit oxidation and prevent the formation of free radicals, which are responsible for cellular damage. Since the oral tissues are vulnerable to cellular damage caused by free radicals and oxidation process hence maintenance, a good level of antioxidants is very essential to achieve optimal oral health. This review highlights the role of antioxidants in the prevention of oral diseases

Techno-economic assessment of distribution system considering different types of electric vehicles and distributed generators

Techno‐economic assessment of distribution system considering different types of electric vehicles and distributed generators

Abstract The global warming crisis, together with environmental concerns, has already led governments to replace traditional fossil‐fuel cars with low‐emission Electric Vehicles (EVs). This replacement has resulted in the addition of a large number of EVs capable of connecting to the grid. A coordinated charging method is needed to promote EVs on a large scale while preventing grid overloading. In this work, EVs are categorized based on their battery capacity, as cars, trucks, and buses. A charging/discharging mechanism based on Real Time Pricing for each hour is developed for a 20‐min block that has been formed. The locations of EV charging stations have been identified using Voltage Stability Index. In the present work, the power loss when Distributed Generator (DG) units are deployed after the EVs are located in the system for charging and discharging is analyzed. The DGs are considered as solar‐based or wind‐based generators for studying the economic benefit of such an investment under two different weather scenarios and topologies on standard test systems. The results thus obtained give an insight into the various technical and economic benefits
