    Delineation of Groundwater Potential Zones Using Analytic Hierarchy Process (AHP) Technique in Balason River Basin of West Bengal, India
    (BlueRose Publishers, 2022) Rahaman, Saidur; Das, Mantu; Saha, Snehasish; Saha, Snehasish; Chakrabarty, Kunal; Das, Mantu
    Groundwater potential remains an essential topic in the Balason river basin of West Bengal, India. Groundwater potentials can be predicted using an integrated analytical hierarchy process (AHP) approach using a GIS and remote sensing. The goal of this study is to create a groundwater potential zone (GWPZ) map for the Balason River Basin that is reliable and based on scientific evidence. In this situation, the AHP of the MCDA method is used to investigate the potential prospect zones for groundwater resources with significant parameters. To create distinctive thematic layers, USGS satellite data, 30 metre spatial resolution of Landsat 8 images and SRTM-DEM data were used. Eight primary influencing factors were selected: geomorphology, lineament density, slope, slope aspect, lithology, soil types, and land use land cover (LULC), and drainage density. The AHP method produces a GWPZ map utilizing significance scale, pair-wise comparison, signifies consistency ratio, normalized, and weighted overlay technique. The GWPZ map comprises "Very poor," "Poor," "Moderate," "Good," and "Very Good" potential zones with 9.91, 38.45, 25.49, 14.61, and 11.83% share of the overall area respectively. Finally, using receiver operating characteristic (ROC) curve analysis, the generated GWPZ map is approved. Furthermore, the best strategies will be to bring up a good level of groundwater recharge zone through water storage and sustainable land use planning. As a result, groundwater availability should be viewed as a measure of progress in the economic sector and the development of a sustainable human civilization.

    Active Death Cases and Recovery Rates of the COVID-19 Pandemic: A Comparative Study of Developed, Developing, and Least Developed Countries of the World
    (NB Publications, 2022) Rahaman, Saidur; Saha, Snehasish; Mandal, Tapash; Chakrabarty, Kunal; Mitra, Nita; Pal, Sujit
    At present, people worldwide are fighting against an unseen enemy. Outbreaks of COVID-19 are on the rise in more than 200 countries worldwide. In the world economy, human life has been dramatically affected. The developed developing, and least developed countries of the world have been affected by the extremities of COVID-19. However, the rate of COVID-19 infection is not the same in every country of the world due to some of their rules and facilities such as treatment, infrastructure, lifestyle, and awareness. The study has been done based on secondary data. Daily data on the number of recovered, active, and deaths cases were collected up to the study endpoint via the Johns Hopkins University data source (https://github.com/CSSEGISandData/COVID-19) on 24 December 2020 at 21.58 GTM and daily situation reports of World Health Organization (WHO). The data used relates to the descriptive statistics and Normalized Z-score and found relations among 15. In Developed countries, on an average, the affected COVID-19 cases were 28.73 people, say 29per thousand; median COVID-19 cases are 27.62 people, say 28 per thousand people. The average recovery rate is 65.95 % in Developed countries. Nevertheless, high confirmed cases have been found in the U.S (1,78,44,690) ...
