    Indian Research Information Network System (IRINS) is a research information management system that provides details of publications and citations by researchers in academic and research institutes in India. It is an undisputed fact that the productivity of researchers is not uniform within and beyond institutions. A quantitative study was formulated to compare the productivity of researchers within and between categories of central university, state university, deemed university, private university, and college. The coefficient of variation (C.V.) and coefficient of range (C.R.) was measured to know about dispersions among data of publications, patents, Scopus citations, and Crossref citations. It was found that central universities and state universities have a higher number of publications and citations whereas colleges have less number of the same. Private universities have less number of publications, however better than colleges in case of citations. Deemed universities have the highest dispersion within the group. It is suggested to increase subscriptions of quality resources in the colleges and private universities and upgrade library services to enhance the quality and quantity of publications by researchers there

    Advanced oxidation processes (AOPs) are widely used for the removal of health hazardous organic pollutants from industrial and municipal wastewater. Reactive Red 24, which has a complex molecular structure with azo aromatic groups, is widely used in textile industry. Degradation of Reactive Red 24 by Photo-Fenton regent has been investigated under irradiation of visible light in aqueous solution. The parameters that influence degradation such as concentration of Reactive Red 24, FeSO4, H2O2, light intensity and pH of the experimental solution were studied. The optimum condition for the photocatalytic degradation of dye was established. The degradation of dye in the dilute solution follows the first order kinetics

    Multi detector computed tomography fistulography in patients of fistula-in-ano : an imaging collage

    Get PDF
    Fistula-in-ano, or perianal fistula, is a challenging clinical condition for both diagnosis and treatment. Imaging modalities such as fistulography, anal endosonography, perineal sonography, magnetic resonance imaging (MRI), and computed tomography (CT) are available for its evaluation. MRI is considered as the modality of choice for an accurate delineation of the tract in relation to the sphincter complex and for the detection of associated complications. However, its availability and affordability is always an issue. Moreover, the requirement to obtain multiple sequences to depict the fistula in detail is cumbersome and confusing for the clinicians to interpret. The inability to show the fistula in relation to normal anatomical structures in a single image is also a limitation. Multi detector computed tomography fistulography (MDCTF) is an underutilized technique for defining perianal fistulas. Acquisition of iso-volumetric data sets with instillation of contrast intothe fistula delineates the tract and its components. Post-processing with thin sections allows for a generation of good quality images for presentation in various planes (multi-planar reconstructions) and formats (volume rendered technique, maximum intensity projection). MDCTF demonstrates the type of fistula, its extent, whether it is simple or complex, and shows the site of internal opening and associated complications; all in easy to understand images that can be used by the surgeons. Its capability to represent the entire pathology in relation to normal anatomical structures in few images is a definite advantage. MDCTF can be utilized when MRI is contraindicated or not feasible. This pictorial review shares our initial experience with MDCT fistulography in evaluating fistula-in-ano, demonstrates various components of fistulas, and discusses the types of fistulas according to the standard Parks classification

    Production, characterization, and applications of a novel thermo-acidophilic L-asparaginase of Pseudomonas aeruginosa CSPS4

    In present investigation, a potential L-asparaginase-producing bacterial isolate, Pseudomonas aeruginosa CSPS4, has been explored to enhance the production and purification of the asparaginase enzyme. Production of L-asparaginase is enhanced using the 'one variable at a time approach (OVAT)'. In Placket Burman (PB) analysis, pH, sucrose, and temperature significantly influence L-asparaginase production. Thereafter, L-asparaginase enzyme was recovered from culture broth using fractional precipitation with chilled acetone. The partially purified L-asparaginase showed a molecular weight of ~35 KDa on SDS-PAGE. L-asparaginase was characterized as a thermo-acidophilic enzyme exhibiting optimum pH and temperature of 6.0 and 60 °C, respectively. These characteristics render this enzyme novel from other available asparaginases of Pseudomonas spp. L-asparaginase activity remained unaffected by different modulators. L-asparaginase of this investigation was successfully employed for acrylamide degradation in commercial fried potato chips, establishing its applicability in food industries

    Lærerstudenters refleksjoner over undervisning og mangfold i norsk grunnskole

    Get PDF
    The purpose of this study is to investigate how preservice teachers reflect on diversity and on teaching pupils from diverse backgrounds. Following a qualitative research design, the empirical data were constructed through focus group interviews with pre-service teachers attending a 4-year initial teacher education programme for compulsory school in Norway. The thematic analysis of focus group interviews yielded three main results, namely differences are individual and considered natural, diversity as a value and challenge, and belief in practice rather than theory. Results suggest that despite their appreciative views towards diversity, the preservice teachers seem to be having a dilemmatic position regarding whether they should treat every pupil the same or differently. Moreover, the results point to the significance of establishing coherence between theory and practice in initial teacher education regarding the preparation of preservice teachers for their work with diverse pupils.Formålet med denne studien er å undersøke hvordan lærerstudenter i den fireårige grunnskolelærerutdanningen reflekterer over mangfold og undervisning av elever som har ulik bakgrunn. Studien er basert på et kvalitativt forskningsdesign, og data er kon-struert ved hjelp av fokusgruppeintervjuer med lærerstudenter i den fireårige grunn-skolelærerutdanningen. Den tematiske analysen ledet fram til tre hovedresultater: Forskjeller er individuelle og forstås som noe naturlig, mangfold som en verdi og utfordring, og vektlegging av praksis heller enn teori. Resultatene viser at til tross for deltakernes verdsetting av mangfold, opplever lærerstudentene dilemma når det gjelder hvordan de skal handle i praksis. Resultatene peker videre på betydningen av å etablere koherens mellom praksis og teori i lærerutdanningen for å forberede lærerstudentene for arbeidet med mangfoldige elevgrupper.publishedVersio

    GPS*(GLOBAL POSITIONING SYSTEM) functionality : Review

    Get PDF
    The Global Positioning System (GPS) is a U.S. space-based radio navigation framework that gives dependable situating, route, and timing administrations to non military personnel clients on a consistent overall premise - uninhibitedly accessible to all. GPS gives uncommonly coded satellite flags that can be handled in a GPS beneficiary, empowering the collector to register position, speed and time. Fundamentally GPS works by utilizing four GPS satellite signs to figure positions in three measurements (and the time balance) in the beneficiary clock. GPS gives exact area and time data for a boundless number of individuals in all climate, day and night, anyplace in the world. Any individual who needs to monitor where he or she is, to discover his or her way to a predefined area, or comprehend what heading and how quick he or she is going can use the advantages of the worldwide situating framework. Regular exercises, for example, managing an account, cellular telephone operations, and even the control of force lattices, are encouraged by the precise planning gave by GPS.
