Impact assessment of river sand resource shortage under
More than half of the annual global concrete materials were produced in China due to the rapid developing construction industry, which partly led to the shortage of river sand. However, mining rate exceeds the natural replenishment rate of river sand recently, resulting in depletion of natural river sand accumulation. The increasing Conversion of natural uranium. Andrew J. Oliver, Engin Özberk, in Uranium for Nuclear Power, 2016 11.7 Potential future developments. Technology, processing, and conversion are not likely to change significantly in the near future. No product other than UF 6 is likely to be in demand for enrichment and the overall demand will only increase slowly. Indeed as Processing Technology an overview ScienceDirect Topics

Automated River Plastic Monitoring Using Deep Learning and
Modern artificial intelligence (AI) technology called deep learning offers the opportunity to make this possible. In fact, deep learning is responsible for recent breakthroughs in signal and image processing (LeCun et al., 2015).It has also been established that by using washed M-sand the cement consumption is at least 5-6% less for the same level of strength in concrete. Centuries-old Sand washing practises. The use of wet processing technology for sand production is an established process across the world.Green Sand Production Techniques Mitigating Environmental Hazards of
