Selective Recovery of Valuable Chemicals from Tire Pyrolysis Oil: A Sustainable Approach
Abstract: The generation of waste/scrap/end-of-life tires (ELTs) poses severe environmental challenges globally. For the disposal of huge numbers of ELTs (generated every year) using conventional recycling methods, like as landfill or incineration, are not preferred due to their adverse environmental impacts. To overcome this problem, an alternative and promising technology is developed -the pyrolysis of waste tires. Pyrolysis is a thermochemical process that decomposes organic materials (Rubber Hydrocarbons) in the absence …

A New Method of Juice Concentration using a Hydrogen Bubbles Photoelectroflotation Process Powered by Solar
Abstract: Currently, juice concentrates are produced by extracting water from freshly squeezed juice. To extract water from freshly squeezed juice, one of the following methods is used: evaporation, freezing of water, or the use of diaphragms. When evaporating, freshly squeezed juice is heated in a vacuum in special trays, but not to the boiling point, since boiling the juice will destroy all its useful substances. The mass, obtained after evaporation is …

Plant Disease Detection Using SVM
Abstract: AbstractDiseases in plants are responsible for major production and economic losses and also reduction in yield. Detection of plant disease through some automatic technique is beneficial as it reduces a large work of monitoring in big farms of crops, and at very early stage itself, it detects the symptoms of diseases. Detection on plant is very critical for defensible agriculture. It is very challenging to monitor the plant diseases physically. …
