KF/Al2O3 as a green and efficient catalyst has been used for the synthesis of mono and bis pyrimidine derivatives via three-component reaction of amidines, malononitrile, and aldehydes in EtOH at reflux. The great advantage of this catalyst is the ease of handling. KF/Al2O3 can be used and removed by filtration, avoid cu...

Waste rock dumping is very important in the production planning of open-pit mines. This subject is more crucial when there is a potential of acid-forming (PAF) by waste rocks. In such a type of mines, to protect the environment, the PAF materials should be encapsulated by non-harmful rocks. Therefore, block sequencing of the mined materials should be in such a way that both the environmental an...

Disparities between the rich and poor continues to increase in many of these regions where growing urban areas often witness the worst signs of maltreatment of human labour and misallocation of waste as a resource. This thesis is a case study of the Municipality ...

Hazardous wastes include numerous kinds of discarded chemicals and other wastes generated from industrial, commercial, and institutional activities. These types of waste present immediate or long-term risks to humans, animals, plants, or the environment and therefore require special handling for safe disposal. Landfills that can accept hazardous wastes are excavated or engineered sites where th...
