 Abstract

The modified Hummer process was used to successfully make graphene oxide (GO) films with a two-dimensional structure. The redox approach has been shown to be a viable method for large-scale GO film production. The characteristics of GO films have been thoroughly characterized. The existence of oxygen-containing functional groups in GO films was confirmed by a Fourier-transform infrared spectrum analyzer (FT-IR). The UV-VIS spectrometer revealed that the GO sheet had excellent optical responsiveness. In this study, the chemical structure of GO sheet was also reported. There is a discussion and references for more graphene research.

 Abstract

Cement is the most commonly used building material, accounting for 7% of worldwide carbon dioxide emissions. The most major contribution to global warming is carbon dioxide. Efforts have been made to minimize CO2 emissions in the environment in every way that is practicable, but cement has yet to find a sustainable substitute. The use of fly ash concrete in building is an effort to minimize the quantity of cement needed. The study's purpose is to look at the use of fly ash concrete in construction as a solution to two environmental challenges. One, enormous volumes of fly ash are disposed of by thermal power plants, causing environmental degradation via vast areas of landfills, and two, the cement industry releases a significant proportion of carbon dioxide into the atmosphere. The growth of concrete technology has been increasingly visible in everyday life as the infrastructure era has evolved in recent years. The use of concrete increased the use of natural resources and energy sources. The presence of fly ash in cement and concrete is unacceptable. Fly ash concrete is both cost-effective and eco-friendly. It also increases the durability of concrete. Currently, less than half of India's fly ash production is used. Infrastructural development is at an all-time high throughout the globe, and it is a good indicator of a country's growth. Throughout the experiment, fly ash was partly replaced for cement and fine aggregate, resulting in a range of 0 percent (without fly ash), 10%, 20%, 30%, 40%, and 60% by weight of cement for M-25 Mix. Concrete mixes' compressive and split strength were molded, tested, and compared.

 Abstract

Distributed ledger technology (DLT) is a digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time. Unlike traditional databases, distributed ledgers have no central data store or administration functionality. In a distributed ledger, each node processes and verifies every item, thereby generating a record of each item and creating a consensus on its veracity. A distributed ledger can be used to record static data, such as a registry, and dynamic data, such as financial transactions. Blockchain is a well-known example of a distributed ledger technology.

 Abstract

This study has examined the impact of the Covid-19 pandemic on the employment status of return migrants and rural poor people of six underdeveloped states like Bihar, Madya Pradesh, Odisha, Rajasthan, UP, and Jharkhand. This study has encompassed with two research questions (a) How does Garib Kalyan Rojgar Abhiyan affect the employment status of returnee migrants during COVID 19 pandemic period? (b) What is the employment status of returnee migrants under MGNREGS during the COVID 19 pandemic period? The data used in the study from the secondary sources like census survey(2011) for out-migration and return migrant (due to covid-19) data from respective state governments' official data, various journal reports, and employment status data from the Ministry of Rural Development, GOI(2020).In this study, descriptive statistics have been used for the analysis of both out-migration and return migration and their employment status. From the analysis, it has been found that 72 percent and 58.31 percent of return migrants have got jobs under GKRA and MGNREGS respectively. After comparative analysis, it has been found that in the states like Bihar, MP, Rajasthan returnee migrants are more benefited from GKRA than the MGNREGA. However UP, Odisha, and Jharkhand returnee migrants are more benefited from MGNREGA than the GKRA.

 Abstract

Well-being is an essential measure that contributes to the evaluation of the health and quality of life of an individual. Being a man or a woman has a significant impact on health. The aim was to study wellbeing among women living in tribal area. The Wellbeing scale developed by Dr.Vijjayalaxmi Chauhan and Dr. Varsha Sharma (2005) was administered to the women. A sample of 100 of working and non-working women of the age group of 30 to 35 years from Tribal area, Manipur was randomly selected for the present study. The tests used to analyze the data were student t-test and chi- square test. The results found a significant difference in the wellbeing level among Working and Non-working women in Tribal area of Manipur. It was also noticed that the working nature, Residence, Type of Family may all contribute to the well-being of an Individual.
