Abstract

The present study is an attempt to highlight the research output generated in India in the field of social sciences and humanities (SSH) during the period 2005–2014. This study is based on secondary data, extracted from the Social Science Citation Index (SSCI) and Arts & Humanities Citation Index (A&HCI), which are integral components of the Web of Science. Descriptive and inferential statistical techniques were applied in the study. There were 9525 articles by Indian scholars in SSH during 2005–2014; they preferred to publish in Indian journals. The research contributions were in the form of research articles and book reviews with a consistent drop in the number of book reviews with time. Co-authorship was the norm in SSH disciplines with a steady increase in the number of multi-author papers in recent years. The study shows that multi-authored research papers received more citations than single-authored papers.

Abstract

Decolourization potential of microalgal biomass of an unicellular green alga (Chlorella vulgaris) was studied using different concentrations of Orange-G dye. Several parameters were also optimized for better removal of the tested dye from its aqueous solution. Langmuir and Freundlich models were tested for equilibrium studies and experimental data of the present study are better explained by the Freundlich model. FTIR data showed that five functional groups were probably involved in the adsorption of the dye. The biosorption process using algae (including C. vulgaris) offers an excellent biosystem for the remediation of final discharge of textile effluents.

Keywords

Adsorption, Chlorella vulgaris, Dyes, Infrared Spectrum.

Abstract

In this study, we screened 26 bioactive compounds present in various spices for activity against SARS-CoV-2 using molecular docking. Results showed that piperine, present in black pepper had a high binding affinity (–7.0 kCal/mol) than adenosine monophos-phate (–6.4 kCal/mol) towards the RNA-binding pock-et of the nucleocapsid. Molecular dynamics simulation of the docked complexes confirmed the stability of piperine docked to nucleocapsid protein as a potential inhibitor of the RNA-binding site. Therefore, piperine seems to be potential candidate to inhibit the packag-ing of RNA in the nucleocapsid and thereby inhibiting the viral proliferation. This study suggests that consumption of black pepper may also help to combat SARS-CoV-2 directly through possible antiviral effects, besides its immunomodulatory functions.

Abstract

The present study assessed the effect of improved agricultural technologies disseminated under the ambitious Farmer FIRST Programme on production costs of major crops in Bundelkhand region, Uttar Pradesh, India. The findings show that the average real cost during 2017–18 to 2020–21 declined, leading to an increase in the net return to cost ratio from farming. Technological interventions at the farmer’s field resulted in a gradual decline in the share of seed, fertilizer and plant protection chemicals in the cost of cultivation. The price elasticity of factors, estimated by fitting the translog function, suggests that policies for controlling input price inflation, particularly wage rate, will be imperative in reducing the cost of farming. The results on the elasticity of technical substitution between labour and machinery highlight the need for devising suitable farm mechanization strategies which may be affordable in the small farm situation as well. The panel data estimate of negative cost elasticity of yield indicates that productivity growth plays a vital role in absorbing the increase in production cost

Keywords

Abstract

The DSSAT-CERES-Sorghum model was used to test performance of four kharif sorghum genotypes to changes in rainfall and temperature over three sowing windows. Three rainfall scenarios (no change, –10%, –20%) and three temperature scenarios (no change, +1°C, +2°C) were incorporated to past 32 year (1985 to 2016) of recorded weather data, and average simulated outputs showed that, irrespective of cultivar and sowing time, reduction in rainfall had minimal effect on crop duration, but lowered grain yield by 3.34% and 12.85% respectively, at –10% and –20% rainfall scenarios. Rise in temperature from current levels to +1°C and +2°C reduced crop duration by 7 and 12 days, while final yield reduced by 9.4% and 20% respectively. Further, per cent reduction in yield increased with delay in sowing under both scenarios. This effect was more pronounced with combined effect of reduced rainfall and increased temperature. CSH-16 cultivar performed the best across scenarios, while the remaining cultivars followed the order: CSV-17 > CSV-23 > CSH-23. Early sowing (15 June) is suitable to attain higher yield compared to 30 June and 15 July sowing across scenarios

Abstract

Groundwater contributes to 9% of India’s GDP; 64% of irrigation, 85% of rural water supply and over 50% of urban water demand. Over the last decade, 54% of India’s shallow wells became defunct due to declining groundwater levels and thus deep wells have been constructed. This shift to deeper wells has led to more groundwater withdrawal than natural recharge resulting in over-extraction. Most of States and Central Government agencies focus on groundwater recharge and conservation to address sustainability through schemes like Jal Shakti Abhiyan and MGNREGA. these interventions between 2017 and 2020 led to a notable 12.46 bcm increase in groundwater resources in hard-rock aquifers. This study’s findings would assist policymakers and administrators in evaluating the effectiveness of schemes for different aquifer, and drawing their attention to suggests design changes for more effective recharge of groundwater.
