Working Architecture of Active Directory Applications in Libraries

Information Technology revolutionized era offer several tools for creating; organizing; storing and visualization of information in libraries in various perspectives. This paper highlights the application of Active Directory in library and information centers. In this context, Active Directory is an extensible directory service that enables managing and storing the detailed information about each network resources efficiently and also used to record the user access count as well as the duration of time spent by the user in the library. It is also used to maintain the institutional User restriction policies in the Server-Client architecture in libraries. This paper explains the steps to deploy the User access and reporting modules, credentials to the user by using the Windows Active Directory and also explores the technical aspect of working architecture, application and its limitation in the libraries

Outcome of reconstruction for duplication of the thumb in adults aged over 40.

Congenital duplication of the thumb is usually reconstructed by 18 months of age. This paper reports satisfactory outcome following reconstruction of two Wassel Type IV duplicate thumbs in adults aged over 40. Both achieved a good outcome based on Tada's criteria and a subjective Visual analogue score 8

Resolving ABO discrepancies by serological workup-an analysis of few cases

Background: ABO discrepancies occur whenever the results of red cell grouping and serum grouping are in disagreement. The reasons for discrepancies both clinical and technical have to be sorted out. Further analysis is essential to resolve such discrepancies. If discrepancies are encountered, the interpretation of the ABO grouping has to be delayed until the same has been resolved. The aim of the study was to resolve ABO discrepancies encountered, by serological work up.Methods: All cases of discrepant samples received between August 2014 and May 2016 at the Department of Transfusion Medicine, The Tamilnadu Dr. MGR Medical University, Chennai, India were analyzed to determine the etiology by serological workup.Results: A total of twenty-one samples were analyzed and resolved. Fifteen cases of Type IV discrepancy, two cases of Type II discrepancy, one case Type III discrepancy, one case Type I discrepancy and two cases of technical errors were identified.Conclusions: ABO discrepancies can be resolved serologically if properly worked up. As ABO blood grouping is indispensible in blood transfusion service, it is imperative to resolve such discrepancies before transfusion

User’s Satisfaction with Library Resources and Services in Polytechnic College Libraries in Coimbatore District

This present study is an investigation of user’s satisfaction with library resources and services in polytechnic college libraries in Coimbatore district. A survey research method was adopted to address the research questions. 150 questionnaires were distributed among final year graduate students, postgraduate students, research scholars and faculty members of polytechnic college libraries to collect relevant data regarding their satisfaction. 130 filled -in questionnaires were received and analyzed. On the basis of finding, some suggestions have included in this study to increase user’s satisfaction from libraries

Study of Information Seeking Pattern of School Teachers in Sri Lanka with respect to Curriculum Planning

The study was conducted to examine information seeking pattern of school teachers in Sri Lanka. The survey method was adapted for this study and a self-administered questionnaire was used as main data collection tool. The school teachers who enrolled to follow postgraduate courses in the Department of Education, University of Peradeniya, Sri Lanka were selected as the study population and the collected data were analyzed using SPSS (21.0). The study found that most of the respondents used face to face discussions and mass media as communication channels and most of the respondents study curriculum, teachers’ guides and students’ text books before preparing the lesson plans. Most of the teachers seek information with a perceived idea in mind. The teachers consider whether the contents of the documents address the topics on the syllabi adequately when evaluating information sources. This study also identified several problems that encounter by the teachers when seeking information for Curriculum planning

Antipyretic activity of azima tetracantha in experimental animals

In the present study, the ethanolic leaf extract of Azima tetracantha Lam (A. tetracantha) was investigated for antipyretic activity in rats using Brewer’s yeast induced Pyrexia. The leaves of A. tetracantha were collected from Ponnamaravathi and cut into small pieces and shade dried. The dried powdered leaves (100 gm) were extracted in a Soxhlet apparatus by using 95% ethanol. Albino rats weighing (200-250g) were taken for the experiment divided into four groups of six animals each. Group 1 received 3% aqueous suspension of gum Acacia (1 ml/200g) as vehicle orally, group 2 and group 3 received ethanolic leaf extract of A. tetracantha 100 and 200 mg/kg with 3% aqueous suspension of gum Acacia orally and the group 4 served as standard received paracetamol 25 mg/kg with 3% aqueous suspension of gum Acacia orally. The subcutaneous injection of yeast suspension markedly elevated the rectal temperature after 18h of administration. Treatment with A. tetracantha extract at a dose of 100, 200 mg/kg decreased the rectal temperature of the rats in dose dependent manner. This effect was maximal at dose of 200 mg/kg and it caused significant lowering of body temperature (P< 0.01) up to 4 hour after its administration. The antipyretic effect started as early as 1h and the effect was maintained for 4h, after its administration. Both the standard drug paracetamol 25 mg/kg and tested drug A. tetracantha extract were significantly reduced the yeast elevated rectal temperature, at 2nd, 3rd and 4th hour compared to control group

Pressure-induced melting of the orbital polaron lattice in La1-xSrxMnO3

We report on the pressure effects on the orbital polaron lattice in the lightly doped manganites $\mathrm{La_{1-x}Sr_xMnO_{3}}$, with $x\sim 1/8$. The dependence of the orbital polaron lattice on $negative$ chemical pressure is studied by substituting Pr for La in $\mathrm{(La_{1-y}Pr_y)_{7/8}Sr_{1/8}MnO_{3}}$. In addition, we have studied its hydrostatic pressure dependence in $\mathrm{(La_{0.9}Pr_{0.1})_{7/8}Sr_{1/8}MnO_{3}}$. Our results strongly indicate that the hopping $t$ significantly contributes to the stabilization of the orbital polaron lattice and that the orbital polarons are ferromagnetic objects which get stabilized by local double exchange processes. The analysis of short range orbital correlations and the verification of the Grueneisen scaling by hard x-ray, specific heat and thermal expansion data reinforces our conclusions.Comment: 7 figure
