Objectives: The objective of our study was to analyze the clinicopathological spectrum and outcome of Cr GN with special reference to its immunopathological subtypes using a panel of immunofluorescence stains. Materials and Methods: Native renal biopsies with crescentic pattern of injury were included. Detailed Clinical and laboratory variables were analyzed along with the treatment protocol and renal outcome, wherever available. Renal biopsy slides were evaluated for various glomerular and extraglomerular features. Both qualitative and quantitative data were analyzed. Results: A total of 57 cases of Cr GN were included; majority (47.36%) of cases were pauci-immune in nature. Among clinical features, ranges of proteinuria and creatinine level were significantly different between subgroups. The various light microscopic parameters, inc...

The data has been extracted from the Web of Science database on the affiliation of basic search. The research output has been derived on the basis of 963 publications receiving 4148 citations with a 4.87 percent average citation per paper. The authorship pattern was dominated by two authors securing 35.099% and collaboration coefficient of 0.488. The country-wise publication was dominated by the United States contributing 159 papers. Out of the total 963 publications, 881(91.5%) are article which seems to top the list. The Journal of Knowledge Management seems to be the often sought journal for publishing KM articles occupying 25.54% of the total publication. However, the highly cited paper appears in MIS Quarterly authored by Kane, G.C et al. The major subject category was the application of Information Communication and Technology (ICT) in KM. Finally, the co-occurrence of keywords throws light on the research interest of the researchers.

Hence in order to stay in the limelight one must keep themselves updated with the latest technological trend. This chapter focuses on the Virtual Reference Service (VRS) provided by eight universities from Tamil Nadu. Various services that can be provided under VRS have been identified based on minimal cost and maximum benefit approach. We have made a comparison of these Universities right from their NAAC grade to NIRF ranking 2019 and eventually the VRS. The amount of funds utilized has also been discussed in comparison to their ranking received. Based on this study one can get a clear idea about the status of VRS provided by these universities.

The idea behind Linked Data can be used to create a huge database of the Internet interlinked by relationships that will be easily understood by machines as well as humans. We tried to compare some libraries that have published their content via linked open data. The advantages and disadvantages have also been highlighted. libraries should benefit by adopting linked Data but there are many challenges that will come up in its implementation. The BIBFRAME Initiative is a possible framework that will enable libraries to link their resources on to the web attracting users with high-quality content. Various initiatives have been undertaken by the libraries in order to make resources accessible to all users.
Webometrics Ranking (WR) of World Universities and National Institutional Ranking Framework (NIRF): A Comparative Study

However, there are certain agencies that regularly undertake such an exercise. In this paper we have considered Webometrics Ranking (WR) and National Institutional Ranking Framework (NIRF) specific to India for our study. Various parameters have been compared citing their features. The methodology used by these rankings have been discussed such as WR depends on web presence and categorises institutions on the basis of Presence rank, Impact rank, Openness rank and Excellence rank whereas NIRF categorises on the basis of Graduation Outcomes, Learning Teaching & Resources, Outreach of students, Research and Professional Practice and Awareness. Indian Institute of Technology Bombay, Maharashtra tops the list in Webometrics Rankings whereas Indian Institute of Technology Madras, Chennai tops the list in NIRF rankings. An interpretation of these rankings along with their limitations have been given finally some conclusions have been drawn on the basis of the data.

METHODS: This study was carried out in the department of renal pathology, in a tertiary referral care center in southern India. All native kidney biopsies reported over 20 months (April 2011 to November 2012) were included in this study. Biopsies from rural as well urban regions across the country are processed here. Obstetric AKI was found in 43(12.9%) patients out of 332 who were biopsied for AKI. In the patients biopsied for obstetric AKI, age, clinical presentation and histopathological diagnosis were analyzed. RESULTS: The age range was 19 to 35 years, with an average of 24.53±3.57 years. Acute renal failure occurred in association with septic abortions or puerperal sepsis in 13 patients (30.2 %), preeclampsia or eclampsia in 11 patients (25.6 %), postpartum hemorrhage in 6 patients ...

This is mainly due to the co-circulation of other genetic subtypes that potentially can recombine to generate recombinant/mosaic genomes. In this study, we report detail genetic characterization of HIV-1 envelope sequences from North India (Delhi and neighboring regions). Six of 13 were related to subtype C, one B and the rest six showed relatedness with CRF02_AG strain. The subtype C possessed the highly conserved GPGQ motif but subtype B possessed the GPGR motif in the V3 loop as observed earlier. While most of the sequences suggested CCR5 co-receptor usage, one subtype C sample clearly indicated CXCR4 usage. A successful mother to child transmission was established in two pairs. Thus, co-circulation of multiple subtypes (B and C) and the recombinant CRF02_AG strains in North India suggests a rapidly evolving scenario of HIV-1 epidemic in ...

Methodology: This study covers articles published in the Web of Science database where 242 articles were taken into consideration and further analysis was done for the stipulated time period. Findings: The research trend of digital library in India consists of 15 core topics and other specific areas, China with 15 core areas as well for the same time period and U.S.A showed 17 core topics for research in digital library topic. The countries most researchable areas as well as related researchable areas has been analysed here. The growth of digital libraries in these countries are highlighted with appropriate diagram. Originality: Here the articles were extracted from Web of Science database for obtaining necessary findings. Major highlighted topics of India were digi...

Every ladder of education has its own problems and prospects. However, attempts have been taken to lessen complexities. From ages, time to time commissions have been constituted to improve and remove the anomalies of Indian education system especially, ensuring quality and uniformity in India education system. Idea of Quality assurance cell has not only been mooted out but also implemented across the national level. Ensuring uniformity in Education System, especially at UnderGraduate level, Choice-Based Credit System has been confirmed mandatory. But the nature of Indian education system is much diverse and encompasses inherent problems of diversity in implementing the uniform system of evaluation. Present education system of India has got spread across the country in the form of Primary Education, Secondary Education and Tertiary Education. The last one of education sector has much importance in the process of developing nation. Major inventions and innovations have direct bearing on the quality of higher education. So, quality is the major concern of the present higher education which could be judged and assessed only by the universally acclaimed system of evaluation and this could be possible through the CBCS. Thus, the present article aims to highlight the merit and demerit of Choice-Based Credit System.
