    (BlueRose Publishers, 2022) Poddar, Debapriya; Mukhopadhay, Sarbari; Mandal, Tapash; Das, Jayanta; Saha, Snehasish; Saha, Snehasish; Chakrabarty, Kunal; Das, Mantu
    Groundwater acts as a significant provider of required water in different sectors of India, like household, agriculture, and industry. A copious amount of water and food resources are needed in Damodar River Basin for the fast expansion of the population, leading to severe strain over the water resources. The analysis of the temporal trends of groundwater level is essential for preserving groundwater for further use. Hence, the principal objective of this work is to examine the temporal trends in the Damodar River Basin in the annual, seasonal time scale from 1996 through 2017, applying the Mann-Kendall (MK) and Sen 's slope estimator tests. The outcome of these analyses represents the positive trends and also the negative trends that have occurred in the case of groundwater depth of the study area. However, decreasing trends are much weaker than increasing trends. Compared with the monsoon season, strong increasing trends have been identified in pre-monsoon, post-monsoon Kharif, and post-monsoon Rabi seasons. The southern region of the Damodar River Basin, where paddy farming requires vast amounts of water, is where the significant positive developments were concentrated. The results of this research will assist policy makers and planners in maintaining a sufficient and consistent

    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) ...
