Exchange bias-like magnetic properties in Sr2LuRuO6

Exchange bias properties are observed in a double perovskite compound, Sr2LuRuO6. The observed exchange bias properties have been analyzed on the basis of some of the available theoretical models. Detailed magnetization measurements show that the exchange bias properties are associated with the Dzyaloshinsky-Moria (D-M) interaction among the antiferromagnetically ordered Ru moments (TN~32K). In addition to the usual canting of the antiferromagnetic moments, D-M interaction in this compound also causes a magnetization reversal at T~26K, which seems to trigger the exchange bias properties. Heat capacity measurements confirm the two magnetic anomalies.Comment: 5 Pages, 6 Figure

Gossip Codes for Fingerprinting: Construction, Erasure Analysis and Pirate Tracing

This work presents two new construction techniques for q-ary Gossip codes from tdesigns and Traceability schemes. These Gossip codes achieve the shortest code length specified in terms of code parameters and can withstand erasures in digital fingerprinting applications. This work presents the construction of embedded Gossip codes for extending an existing Gossip code into a bigger code. It discusses the construction of concatenated codes and realisation of erasure model through concatenated codes.Comment: 28 page

A controlled clinical trial to evaluate the efficacy of Tilanala Kshara in the management of Vatashteela vis-a-vis Benign Prostatic Hyperplasia

Background: Benign prostatic hyperplasia is the most common urological disease among elderly men, which is characterized by hypertrophic nodular changes of the prostate gland, which is located at the base of the bladder surrounding the proximal urethra. Gland grows at the rate of 2.4cm3/year after the age of 40 owing to the change in hormonal environment. In India, the prevalence rate is around 50% in men above the age of 65 years. The condition can be corelated to Vatashteela in Ayurveda based on the symptomatology. Objective of the study:  To evaluate the efficacy of Tila Nala Kshara in the management of Muthraghata vis-a-vis BPH.  Materials and Methods: A double arm open labelled clinical study with pre-post-test design was carried out at Government Ayurveda Medical College and Hospital, Mysuru. Data was collected as per the proforma prepared for the purpose of the study. Tila Nala Kshara was administered as intervention in 54 subjects and the control drug was Gokshuradi Guggulu. The data was analysed using SPSS descriptive and inferential statistics. Results: Among the objective parameters, change in prostate volume was significant between the groups with a P value 0.024. But for postvoid residual volume, the difference between the groups was not statistically significant. For subjective parameters which includes IPSS total and Quality of life scale, the difference between the groups was statistically nonsignificant. Conclusion: Tilanala Kshara when used along with Gokshuradi Guggulu was observed to improve general condition of the subjects to greater extent, which clearly implies the added effect of the trial drug

Coral reef research in India: A Bibliometric analysis (Part-I)

Part-I of this paper attemps to evaluate the coral reef research in India using Bibliographic tools for the period 1900-2000. The data has been extracted from "Bibliography on Indian coral reefs". It highlights research productivity by subjects, domains, institutions (Research and Academic) etc. The study examines authorship pattern, productivity on individual scientists and also identified the various countries - participation. It analyzes the forms of communication, journals productivity and identified criteria for selection of the core journals for library. Suggested to create a database on coral reefs and to develop marine science at national level that would facilitate easy use of all categories of people

E-learning: A new way of Library and Information Science Education through Distance Mode

This study explored that the e-learning mechanism is required to provide for quality of Library and Information Science education at university level through the distance learning. This paper is divided into three sections. The first section deals with the LIS education in distance mode. Second section examines the developments of E-learning and LIS education in India. Third Section spells out the universities are forced to face the following major challenges to adopt e-learning mechanisms, which are to design LIS programmes to fit into the e-learning environment, to provide quality education, the teachers aswellas students are to be trained the information technology advancement, to enhance LIS education e-learning consortium, collaboration, quality assurance with accreditation and cost effective were discussed in details to strengthening the LIS education

STREPTOZOTOCIN-INDUCED OXIDATIVE STRESS IN DIABETIC RATS - A DEFENSIVE EFFECT OF PSYDRAX DICOCCOS

Objective: The present study was aimed to evaluate the antihyperglycemic activity and in vivo antioxidant effect of methanolic extract of whole plant of Psydrax dicoccos (MEPD) belonging to the family Rubiaceae.Methods: MEPD was prepared by Soxhlet extraction. Wistar rats weighing (180–200 g) were divided into six groups (n=6), with three doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg of extract. Metformin was used as a standard drug. Diabetes was induced by streptozotocin (STZ) (40–50 mg/kg, i.p) in control group. The animals were treated with different doses of extracts for 21 days, and on the 22nd day, the blood glucose levels along with antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and lipid peroxidase (LPO) were determined.Results: The phytochemical screening of the extract showed the presence of carbohydrates, phenolics, flavonoids, glycosides, and tannins. The methanolic extract of MEPD at the dose of 200 mg/kg body weight showed a significant reduction in blood glucose levels (**p<0.001) with the value of 151.2 mg/dl on the 22nd day at 8 h. A promising antioxidant effect was also evident from the determination of antioxidant enzymes such as SOD, CAT, and LPO.Conclusion: The P. dicoccos extract revealed a potential effect of antihyperglycemic activity and combating nature on oxidative stress induced by STZ
