Usage pattern of Library Resources and Services by the Students and Faculty Members of B.Ed Colleges Affiliated to Kuvempu University

This study explores user perception, the use of an academic library, and the correlation between user perception and library use. The findings indicate that the B.Ed College library is a preferred place to study and spend time during non-class times on campus. The frequent user activities in the library included individual study, reading, computer use, finding information, group study, using reference and information services, and meeting and socializing. The correlation between library use and each of the user activities was examined. The findings suggest that users perceive the B.Ed College library primarily as a place for learning and information seeking. The study shows how users perceive and use the library, and provides insights into how libraries can strengthen their place and advance their role in the academic community

Knowledge and use of electronic information resources by Post graduate Engineering students of Karnataka state: A study

The present study is an attempt to know the knowledge and use of electronic information resources by post graduate engineering students studying in 16 Autonomous engineering colleges of Karnataka state. The study involved 1064 post graduate engineering students and found that 100% students use electronic information resources. The study also revealed that e-journals are the most preferred e-resources and the library notice board along with library websites are the major sources of creating awareness about the availability of e-resources. However, the trial and error method was highly used to use e-resources followed by self-study and library orientation. The study found that keyword search is highly preferred and the VTU consortium is a highly preferred gateway for accessing the e-resources. Engineering students lack the skill of selecting the right search term. Apart from this slow internet connectivity also hinders the effective use of e-resources

On the recurrence of Noctiluca scintillans bloom in Minnie Bay, Port Blair: Impact on water quality and bioactivity of extracts

A Noctiluca scintillans bloom in the coastal waters of Minnie Bay, Port Blair was studied. Physico-chemical and biological properties of bloom-infested waters were monitored during the bloom period lasting five days. The bloom appeared as a green streak along the entire coastline of Minnie Bay, with cell counts of 17 103 cells/ l. The bloom appeared as a sudden spurt in cell number and persisted for a period of 48 h. The antibacterial properties of extracts from this algal species were also investigated. Conspicuously, the bloom inhibited the common resident phytoplankton species. Total suspended solids showed a marked increase during day-one of bloom compared to ambient levels. The bloom appeared to be limited by dissolved inorganic nitrogen species availability. The differential growth of phytoplankton reveals the involvement of specific trigger factors for such blooms. From the present viewpoint, micro-scale studies on hydrobiological factors preceding the onset of bloom would reveal what cycle of events lead to a bloom and the causal factors of such blooms. However, prediction of occurrence of such blooms and in situ measurements are practical difficulties to be addressed. Since a similar bloom was reported earlier in 2001, it is worthwhile to keep a watch and investigate as to whether there is any anthropogenic or environmental cause for the recurrence of the bloom

Exploring the mechanical, tribological, and morphological characteristics of areca fiber epoxy composites reinforced with various fillers for multifaceted applications

This investigation is primarily concerned with the effect of fly ash, basalt powder, and tungsten carbide (WC) on the mechanical, microstructural, and tribological behaviour of areca fiber-reinforced composites. The fillers (5–10 wt. %) were included with the areca fiber epoxy reinforced composites. In comparison to areca fiber composites without fillers, the inclusion of fly ash, basalt powder, and WC increased the tensile strength by 33–48.2 MPa. The tensile strength of an A2 composite containing areca fiber (20 wt. %), epoxy (70 wt. %) and basalt powder (10 wt. %) was measured to be 48.2 MPa. Similarly, filler incorporation enhanced flexural, impact, and Shore D hardness properties by up to 21.25%, 13.18%, and 15.66%, respectively. Furthermore, the hybridization of fillers enhanced the mechanical properties and abrasion resistance of areca fiber reinforced composites. The inclusion of filler increases the load-carrying capability and adhesion, as determined by SEM. The river-like pattern demonstrates that ductile failure was dominated in the A5 [areca fiber (20 wt. %), epoxy (70 wt. %), fly ash (5 wt. %) and basalt powder (5 wt. %)] composites. A4 [areca fiber (20 wt. %), epoxy (70 wt. %), fly ash (5 wt. %) and tungsten carbide (5 wt. %)] composite has a lower wear resistance than all other composites. The hybrid filler-reinforced composite exhibits increased wear resistance as a result of the absence of wear detritus and textured surfaces.

Facts and Treatment of Bullous Pemphigoid: A Review

Bullous pemphigoid (a type of pemphigoid) is an autoimmune pruritic skin disease that typically occurs in people aged over 60, that may involve the formation of blisters (bullae) in the space between the epidermal and dermal skin layers. It is classified as a type II hypersensitivity reaction, which involves formation of anti-hemidesmosome antibodies, causing a loss of keratinocytes to basement membrane adhesion. Pemphigus and bullous pemphigoid are autoantibody-mediated blistering skin diseases. In pemphigus, keratinocytes in epidermis and mucous membranes lose cell-cell adhesion, and in pemphigoid, the basal keratinocytes lose adhesion to the basement membrane. Pemphigus lesions are mediated directly by the autoantibodies, whereas the autoantibodies in pemphigoid fix complement and mediate inflammation. In both diseases, the autoantigens have been cloned and characterized; pemphigus antigens are desmogleins (cell adhesion molecules in desmosomes), and pemphigoid antigens are found in hemidesmosomes (which mediate adhesion to the basement membrane). This knowledge has enabled diagnostic testing for these diseases by enzyme-linked immunosorbent assays and dissection of various pathophysiological mechanisms, including direct inhibition of cell adhesion, antibody-induced internalization of antigen, and cell signaling. Understanding these mechanisms of disease has led to rational targeted therapeutic strategies

Assessment of phytoplankton diversity, distribution, and environmental variables along the southeast coast of India

Coastal waters are dynamic because of anthropogenic activities that contribute nutrients and contaminants. These changes have the potential to alter patterns of primary production and thus pelagic food webs. Here, we investigated the spatial variation of the phytoplankton community and its response to changing environmental variables at 84 stations along the five coastal districts of Tamil Nadu (TN). During the present study, 85 phytoplankton species were recorded, such as diatoms (64), dinoflagellates (18), silicoflagellates (1), and Cyanophyceae (2). The maximum phytoplankton abundance was recorded on the Thanjavur coast and gradually decreased towards the south coast of Tamil Nadu. Among the phytoplankton community, 50% was dominated by pennate diatoms, attributed to higher NO3− concentrations in the coastal waters due to agricultural discharge. Cluster analysis revealed that Ramanathapuram and Tirunelveli formed a closed cluster, whereas Thanjavur and Pudukottai formed a separate closed cluster associated with higher nutrient and metal concentrations, highlighting the difference in physicochemical parameters between the northern and southern districts of the TN coast. Relatively high nutrient concentrations in the coastal waters of northern districts are of greater concern, which could impact the coastal ecosystem. Coastal eutrophication is becoming a widespread phenomenon, causing disruption in the food chain and ecosystem balances and hence requiring regular monitoring and management

Pharmacoinformatic investigation of medicinal plants from East Africa

Medicinal plants have widely been used in the traditional treatment of ailments and have been proven effective. Their contribution still holds an important place in modern drug discovery due to their chemical, and biological diversities. However, the poor documentation of traditional medicine, in developing African countries for instance, can lead to the loss of knowledge related to such practices. In this study, we present the Eastern Africa Natural Products Database (EANPDB) containing the structural and bioactivity information of 1870 unique molecules isolated from about 300 source species from the Eastern African region. This represents the largest collection of natural products (NPs) from this geographical region, covering literature data of the period from 1962 to 2019. The computed physicochemical properties and toxicity profiles of each compound have been included. A comparative analysis of some physico-chemical properties like molecular weight, H-bond donor/acceptor, logP(o/w), etc. as well scaffold diversity analysis has been carried out with other published NP databases. EANPDB was combined with the previously published Northern African Natural Products Database (NANPDB), to form a merger African Natural Products Database (ANPDB), containing similar to 6500 unique molecules isolated from about 1000 source species (freely available at http://african-compounds.org). As a case study, latrunculins A and B isolated from the spongeNegombata magnifica(Podospongiidae) with previously reported antitumour activities, were identified via substructure searching as molecules to be explored as putative binders of histone deacetylases (HDACs)
