Lack of safe water prevents 42 percent of the world's population from accessing sanitation. In 2021, the WHO estimated that there would be 784 million people without access to safe drinking water. With a well-planned system, the group aims to cut the number of people in need of drinkable water by half by 2015. These methods improve saltwater, which makes up 97 percent of the world's water. In this regard, a model that simulates the work of groundwater treatment firms using natural resources and renewable energy has been developed. There was a lack of continuous wind energy throughout most of Oman, where this model was put, and the necessity for a reverse osmosis system for constant maintenance because these projects rely on renewable energy everywhere. This article aims to create an autonomous desalination plant powered by solar and wind energy. A simulator model based on renewable energy groundwater purification systems was created for this aim. To treat subterranean water in distant areas of Oman using two renewable technologies to create enough electricity to run the reverse water purification and water purification system at the lowest cost. A turbine mounted vertically with a height of 1.5 meters and a diameter of 1 meter will produce 2304 liters per day and 800000 liters per year. [ABSTRACT FROM AUTHOR]

In most structural failures, deterioration of reinforced concrete structure is due to corrosion of reinforcing bars. Ingress of chloride ions and reaction of carbon dioxide with the cement paste due to poor-quality concrete or inadequate cover are the main causes of corrosion. Corrosion can be reduced by using high-quality concrete and providing proper cover to reinforcement. In addition, corrosion inhibitors are used to protect the reinforcement in order to extend the service life of concrete structures. This research work is focused on determining the effectiveness of corrosion inhibitors under cracked and uncracked sections of U-shaped beam. The U-shaped beam concept was used in this study, which helps to develop the crack width within 0.3 mm as per IS: 456 code provision. The two vertical stubs of the U-shaped beam were stressed in order to generate the cracks at the soffit of the beam. Then, the beams are tested for accelerated corrosion along with the half-cell potential meter calculations for the corrosion potential measurement. [ABSTRACT FROM AUTHOR]
