Recent Trends in Digital Library Publications: A Scientometric Analysis

The study seeks to illustrate the most current trends in digital library research via the use of scientometrics. The study of scientific networks is important in many scientific domains. A social network with many nodes and connections serves as the foundation for scientific network research. Nodes include authors, publications, and journals, while linkages include citations, cocitations, and coauthorship. Data was collected from the Scopus abstracting and citation database for the period of ten years from 2012 to 2021. The most relevant 1957 documents were chosen from the collection, and selected documents were analyzed using Biblioshny and VOSviewer. The research showed that digital library productivity is rising annually, the United States of America dominates the production of scholarly production on digital libraries, and research is increasingly focused on digital resource and digital collection development. However, artificial intelligence, deep learning, machine learning, big data, and other related areas of study have emerged as the most recent research trends in digital library research. The outcomes of this study will aid digital library research by providing up-to-date and reliable research information

Distribution pattern of freshwater cyanobacteria in Kaiga region of Western Ghats of Karnataka

This study deals with the identification of 59 cyanobacterial species belonging to 27 genera from different freshwater habitats of Kaiga in Uttara Kannada district of Karnataka during the period from June 2009 to May 2011. Samplings were made during pre-monsoon; monsoon and post-monsoon sampling have been carried out for the duration of 2 years. The study deals with the occurrence of cyanobacterial species in five different aquatic habitats in Kaiga region, with respect to a change in the physico-chemical properties of water. The cyanobacterial diversity is maximum in monsoon season compared to post-monsoon; it was least during pre-monsoon. Among cyanobacteria non-heterocystous filamentous forms were dominant followed by unicellular forms, whereas heterocystous forms were least in number. It was also found that the physicho-chemical properties of water have the influence on the richness of cyanobacterial community. This study indicates the maximum occurrence and abundance of Chroococaceae (23.73%) and Phormidaceae (18.64%) members in all the sites, whereas Stigonemataceae (1.7%) shows very less occurrence. Among the cyanobacteria identified non-heterocystous filamentous forms were dominant followed by unicellular forms; whereas heterocystous forms were least in number.Â

Settlement Analysis of Reinforced Granular Beds near Bridge Abutments

An approach slab is constructed to provide a smooth transition between the bridge deck and the existing roadway pavement. The differential settlement between the bridge deck and the approach slab leads to the formation of a "Bump" at the bridge. This is mainly due to difference support systems for the bridge deck and the slab. A detailed literature review had been done on the causes and the mitigation techniques available

Effect of Dilatancy Angle on Bearing Capacity

In Mohr-Coulomb failure criterion, the angle of shearing resistance of soil is assumed to be constant along the slip plane. However, over the second half of the last century, it is well recognized that the dilatancy angle influences the shear strength of sand. Many researchers have proposed correlations between the angle of shearing resistance at peak state in terms of intrinsic soil variables and soil state variables. Studies on the effect of dilatancy angle of soil, ψ, on the load-settlement response of a strip footing are available in the literature. However, in most of these studies, ψ equal to zero or equal to angle of shearing resistance of soil, is assumed, and only limited studies are available to predict the load-settlement response of strip footing when the dilatancy angle of sand lies between zero and In the present study, the effect of dilatancy angle of sand on the loadsettlement response of a rigid strip footing resting on sand and on the formation of slip planes is studied by varying the dilatancy angle ranging from zero to the angle of shearing resistance of soil (i.e., ψ =0 to

Genetic evaluation for understanding combining ability effects and Heterotic grouping in Maize (Zea mays L.)

Combining ability of the genotypes/lines is a major factor in planning the breeding programme and for development of Heterotic hybrids. In the present study, twenty maize inbred lines were crossed to three diverse testers CM-111, GPM-549 and GPM-581 and the resultant F1 hybrids were evaluated in an alpha lattice design. General combining ability of lines which is representation of additive gene action was found to be significant for all the quantitative traits. Specific combining ability which is indication of non-additive gene action was found to be significant for the traits number of kernel rows per cob, number of kernels per row, cob girth, cob length, test weight and grain yield. Lines VL-058725, VL-1018527 and VL-108723 produced heterotic hybrids in cross combination with any of the tester due to their high GCA effects. Whereas, the lines VL-0536, SNL-1574 and VL-109086 interacted positively with their testers thus producing heterotic hybrids with high positive SCA. GGE biplot analysis was helpful in visualizing the combining ability effects and identify heterotic pattern among theinbred lines. Heterotic grouping based on SCA and mean grain yield was able to classify thirteen of the twenty inbred lines into two distinct heterotic groups i.e., Heterotic group A and B consisting of six and seven lines respectively. Heterotic group A consisted of lines with high GCA whereas, heterotic group B with low GCA lines. SCA effect showed significant positive correlation with all the quantitative traits and played a prominent role in determining the performance of hybrids, thus indicating the importance of non-additive gene action in developingheterotic hybrids

Gastroprotective Properties of Karanjin from Karanja (Pongamia pinnata) Seeds; Role as Antioxidant and H+, K+-ATPase Inhibitor

Plant extracts are the most attractive sources of newer drugs and have been shown to produce promising results for the treatment of gastric ulcers. Karanjin, a furano-flavonoid has been evaluated for anti-ulcerogenic property by employing adult male albino rats. Karanjin (>95% pure) was administered to these rats in two different concentrations, that is, 10 and 20 mg kg−1 b.w. Ulcers were induced in the experimental animals by swim and ethanol stress. Serum, stomach and liver-tissue homogenates were assessed for biochemical parameters. Karanjin inhibited 50 and 74% of ulcers induced by swim stress at 10 and 20 mg kg−1 b.w., respectively. Gastric mucin was protected up to 85% in case of swim stress, whereas only 47% mucin recovery was seen in ethanol stress induced ulcers. H+, K+-ATPase activity, which was increased 2-fold in ulcer conditions, was normalized by Karanjin in both swim/ethanol stress-induced ulcer models. Karanjin could inhibit oxidative stress as evidenced by the normalization of lipid peroxidation and antioxidant enzyme (i.e., catalase, peroxidase and superoxide dismutase) levels. Karanjin at concentrations of 20 mg kg−1 b.w., when administered orally for 14 days, did not indicate any lethal effects. There were no significant differences in total protein, serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase and alkaline phosphatase between normal and Karanjin-treated rats indicating no adverse effect on major organs. During treatment schedule, animals remained as healthy as control animals with normal food and water intake and body weight gain
