WEBOMETRIC STUDY OF NATIONAL INSTITUTIONAL RANKING FRAMEWORK (NIRF) LISTED COLLEGE WEBSITE WITH SPECIAL REFERENCE TO LIBRARY WEB PAGES

The present study is an analysis of National Institutional Ranking Framework (NIRF) listed top 20 college website under the college category on NIRF websites with special reference to library web pages in the year 2021. A total of top 20 NIRF listed college website selected for the study. The study focused on webometric analysis, which examines the domain, domain age and all three types of web impacts factors. To collect data in this study, various small SEO tools such as opensiteexplorer.org (now moz.com), duplichecker.com and smallseotools.com had used to find out domain age, domain authority, page authority and total, internal and external links and alexa global and India rank of college library websites covered in this study. Findings revealed that the Loyola College website having the oldest domain registered on October 24, 1997, and the common highest Domain Authority score of 60 was achieved by Kirorimal College Delhi and Acharya Narendra Dev College New Delhi with the first position among all colleges. Among the top 20 colleges websites, St. Stephens College Delhi achieved the highest page authority score of 34. It was also found that 12 colleges from Delhi state achieved a place in NIRF ranked top 20 colleges of India

Pyrolysis Kinetics of Lignocellulosic Waste Biomass (Cicer arietinum) using Iso-conversional Methods

A study on kinetic analysis of Bengal gram stalk (BGS), an agricultural waste biomass, was carried out using thermogravimetric analyser in an inert atmosphere. Thermogravimetric (TG) and Derivative thermogravimetric (DTG) curves were obtained by varying heating rates at 10°C.min−1, 20°C.min−1, 30°C.min−1, and 40°C.min−1. Three iso-conversional methods viz. Flynn- Ozawa-Wall, Kissinger-Akahira-Sunose, and Starink were applied to determine the kinetic properties and simultaneously obtained the effective activation energies for BGS pyrolysis. The average activation energy (Eα) calculated for BGS was 113.37 kJ.mol-1 for FWO; 109.47 kJ.mol-1 for KAS, and 112.36 kJ.mol-1 for Starink method, respectively. The results showed that the effective activation energies for the pyrolysis of BGS varied with the degree of conversion (α) in the range of 0.1 to 1.0. The experimental analysis revealed the correlation between activation energy and conversion factor

Gasification of Crop Residue Briquettes in an Open Core Down-draft Gasifier

Gasification of crop residue briquettes was studied in an open core, throatless, down-draft gasifier of 1800 MJ.h-1 capacity. Briquettes of 25, 35 and 55 mm diameters were prepared using sugarcane baggase, cotton stalk and ground nut shell, separately, in a piston press briquetting machine. Series of experiments were conducted to study performance of the gasifier in terms of fuel consumption rate, calorific value of producer gas and gasification efficiency using briquettes of selected crop residue. The performance was compared with the performance data already available for babul wood. The gasifier was found working satisfactorily with the babul wood and briquettes of all the three crop residues of three sizes. The gasification efficiency was highest for groundnut shell briquettes, followed by babul wood, sugarcane baggase briquettes and cotton stalk briquettes. The study revealed that clinker formation was lower and calorific value of the gas higher for gasification of smaller sized biomass briquettes
