Prediction of Particulate Matter PM2.5 Using Bidirectional Gated Recurrent Unit with Feature Selection
Air Quality
In recent years, air pollution has increased with industrialization and urbanization globally. It is an important hazardous factor that causes severe health issues to community’s health. Among the number of pollutants in air, PM2.5 is very dangerous due to its very small, 2.5µm, diameter. The PM2.5...

GC-MS characterization of Polygonatum geminiflorum depicted by antibacterial efficacy of the biosynthesized silver nanoparticles using its leaf extract
Environmental Toxicology and Biogeochemistry of Ecosystems
The biological synthesis of nanomaterials is drawing immense interest because of their non-hazardous nature and enormous antimicrobial application. In the present study, we explored Polygonatum geminiflorum Decne for phytochemical profiling and biosynthesis of silver nanoparticles to control soft...
Predictive Modeling for Solar Desalination Using Artificial Neural Network Techniques: A Review
Desalination
Due to the limitations of fossil fuels and the environmental problems associated with their usage, renewable energy sources have been exploited for desalination through the employment of various technologies and mediums. One of the most useful renewable energy sources for solar desalination, both...

Prediction of Ozone Depletion Levels using Intelligent CNN-SVM Classification System
Environmental data analysis and modelling
The concentration of ozone in the earth atmosphere has been steadily falling by 4% in the total amount since late 1970. With the widespread usage of modern industry chlorofluorocarbons, the rate at which ozone content decreases is escalating, resulting in an ozone hole. The depletion permits harmful...
Utilization of cement power plant beds for aerated concrete thermal blocks
Water treatment
Nowadays cement industry power plant bed wastes can be used to create aerated concrete blocks for widespread usage in the construction sector instead of sand. The optimum materials for building enclosures for a variety of uses include aerated concretes. To enhance the physical and mechanical...
