These instruments include GDP growth, unemployment rate, inflation rate, FDI. Using these variables, it was found that the economy of a nation is totally dependent on these factors. The objective of the project is to know the effectiveness of monetary policy in India & analyze the impact of selected monetary instruments on the Indian Economy.

Designated by Ramsar convention, East Kolkata Wetland is the largest natural sewage treatment system that is ecologically productive and provides a unique ecosystem with varieties of flora and fauna. East Kolkata wetland is bounded by Kolkata megalopolis in the west and satellite township Rajarhat Newtown in the north. The Kolkata metropolitan city generates more than 800 million litres of sewage everyday which is purified by the natural purifier, East Kolkata Wetland. It is said to be the ‘Kidney of Kolkata’ as it also sequesters carbon and absorbs the city’s storm water during floods. The importance and benefits of East Kolkata Wetland is immense, but the sad irony lies in the fact that due to certain unplanned and rapid urban expansion of Kolkata city, this great ecosystem is under threat to urbanisation. There has been significant challenge for East Kolkata Wetland with the expansion of Kolkata city and also increase in urban landfills. East Kolkata wetland is bounded by Kolkata megalopolis in the west and satellite township Rajarhat Newtown in the north. In this perspective, the main objective of the paper is to study the temporal land use changes of 30 years and factors responsible for the rapid transformation. Land use and land cover map has been prepared to observe the temporal changes along with the analysis of the perception of local people.

The most flexible branch of computer science is artificial intelligence (AI). It contributes to the development of intelligent machines capable of executing activities that would normally need human intelligence. The medical sector is looking for innovative tools to monitor and control the spread of the COVID-19 (Coronavirus) pandemic in this global health disaster. AI offers numerous technologies or systems that aid in tracking the transmission of this virus, identifying high-risk patients, and controlling this infection in real time. AI can also forecast mortality risk by gathering and evaluating past data from patients. These AI-based solutions can assist us in fighting this illness by scanning the population, providing medical assistance, notifying us, and making infection- control recommendations.
