Centralized collection and disposal is an integral component of waste management strategies for many solid and liquid wastes, and carbon capture and storage is currently being considered for gaseous waste. In this paper we show how collective waste disposal systems introduce essential changes in the design of optimal environmental policy. Absent collective disposal, an optimal environmental pol...

Slope failures pose a substantial threat to mining activity due their destructive potential and high probability of occurrence on steep slopes close limit equilibrium conditions, which are often found both in open pits waste tailing disposal facilities. The development slope monitoring modeling programs usually entails the exploitation situ remote sensing data, together with application numeric...

In this volatile post-COVID environment where customers look for ways to order products online using personal computers and mobile devices, a traditional sale/delivery of via single distribution channel needs be reassessed. As revolutionary alternative conventional channel, paper proposes an omni-channel strategy. The aims maximize the customer shopping experience by diversifying integrating pr...

BACKGROUND Children's stool disposal is often overlooked in sanitation programs of any country. Unsafe disposal of children's stool makes children susceptible to many diseases that transmit through faecal-oral route. Therefore, the study aims to examine the magnitude of unsafe disposal of children's stools in India, the factors associated with it and finally its association with childhood diarr...
