Shimoga, India

Kuvempu University is a public state university located in Shimoga, Karnataka, India. It was established in 1987 by the act of the Karnataka state legislature through an amendment No.28/1976 dated 29 January 1989 under the Karnataka State University Act 1976. The university offers undergraduate and graduate degree programs in wide range of disciplines. It occupies 230 acres of land. The university was recognized by the UGC in 1994 and is a member of the Association of Indian Universities .The university has its headquarters at Jnana Sahyadri Campus, Shimoga. Its campus is called Jnana Sahyadri, which means The Western Ghat section of knowledge. It has as university jurisdiction over malnad districts of Shimoga and Chikmagalur, through which the Sahyadri mountain ranges pass. It also covers districts of Davangere and Chitradurga but now the two places have their own universities, hence is limited to affiliating reseach centers just like anywhere else in India. The campus sprawls across an area of 230 acres. The campus inmates can find some admixture of wild animals and domestic animals. Nature was never so beautiful before like it is inside Jnana Sahyadri.

To reinforce the hydroxyethyl cellulose for using it in biomedical and pharmaceutical applications as a drug delivery systems, the grafting of acrylamide onto hydroxyethyl cellulose (AAm-g-HEC) was achieved by Ce(IV) induced free radical polymerization. The AAm-g-HEC was then blended with sodium alginate (NaAlg) to prepare pH-sensitive interpenetrating network (IPN) microspheres (MPs) by emulsion-crosslinking method using glutaraldehyde (GA) as a crosslinking agent. The produced MPs are almost spherical in nature with smooth surfaces. Diclofenac sodium (DS), an anti-inflammatory drug, was successfully encapsulated into the MPs. The % encapsulation efficiency was found to vary between 54 and 67. The MPs were characterized by DSC, SEM and FTIR spectroscopy. In vitro release studies were carried out in simulated gastric fluid of pH 1.2 for 2 h followed by simulated intestinal fluid of pH 7.4 at 37 C. The release data have been fitted to an empirical equation to investigate the diffusional exponent (n), which indicated that the release mechanism shifted from anomalous to the super Case-II transport. © 2014 Elsevier Ltd.

The semi-interpenetrating networks (semi-IPNs) of acrylamide grafted sodium alginate (AAm-g-NaAlg) microspheres (MPs) were prepared by emulsion-crosslinking method using glutaraldehyde (GA) as a crosslinking agent. The grafting of acrylamide onto sodium alginate was prepared by free-radical graft polymerization using ceric ammonium nitrate (CAN) as initiator at three acrylamide concentrations with monomer to polymer ratio of 1:1, 2:1 and 3:1, respectively. The grafting efficiency was found to be 91%. The produced MPs are almost spherical in nature with smooth surfaces. Diclofenac sodium (DS), an anti-inflammatory drug was successfully encapsulated into the MPs. The encapsulation efficiency was found to vary between 83% and 95%. The MPs were characterized by differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The diffusion coefficient (D) was dependent upon the amount of crosslinking agent (GA) and amount of grafting ratio in the matrix. The rate of release was found to be dependent on the amount of GA, AAm:NaAlg grafting ratio and % drug loading in the MPs. The release data have been fitted to an empirical equation to investigate the diffusional exponent (n), which indicated that the release mechanism from MPs follows the super Case II transport. © 2013.

Study investigates the availability, persistence and half life of URL citations cited in two Indian LIS journals articles published between 2002 and 2010. This study also investigates how researchers can resurrect lapsed URL citations cited in research articles, using Wayback machine. A total of 1290 URLs cited in 472 research articles published in Indian LIS journals spanning a period of 9 years (2002-2010) were extracted. Study found that only 18.91% (1290 out of 6820) of URLs cited in these journal articles. 39.84% of URL citations were not accessible and remaining 60.15% of URL citations were still accessible. The HTTP 404 error message-" page not found" was the overwhelming message encountered and represented 54.86% of all HTTP error messages. However 51.06% URLs were recovered from HTTP 404 error message. Study also noticed that the half-life of URL citations was increased from 6.33 years to 13.85 years after recovering missing URLs from Wayback machine. © 2012 Elsevier Ltd. Source

Electrochemical oxidation is an effective wastewater treatment method. Metal oxide-coated substrates are commonly used as anodes in this process. This article compiles the developments in the fabrication, application, and performance of metal oxide anodes in wastewater treatment. It summarizes the preparative methods and mechanism of oxidation of organics on the metal oxide anodes. The discussion is focused on the application of SnO2, PbO2, IrO2, and RuO2 metal oxide anodes and their effectiveness in wastewater treatment process. © 2013 Springer-Verlag Berlin Heidelberg.

The Zn and Zn-ZrO2 composite coatings were produced by electrodeposition technique using sulphate bath. ZrO2 particles were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The ZrO2 particle size distribution in the plating bath and Zeta potential and the ZrO2 were measured using dynamic light scattering technique (DLS). The corrosion resistance properties of Zn and Zn-ZrO2 composite coatings were compared by examining the experimental data acquired through polarization, open circuit potential (OCP) and Tafel measurements. The corrosion environment was 3.5 wt% NaCl solution. The variation of amount of ZrO2 in the solution on their % wt inclusion in the composite and on composite microhardness was investigated. XRD patterns were recorded for Zn and Zn-ZrO2 coatings to compare their grain size. The SEM images of coatings before and after corrosion under chemical and electrochemical conditions were presented. The results were analyzed to establish the superiority of Zn-ZrO2 composite over Zn coating. © 2011 Elsevier B.V. All rights reserved. Source
