The research paper reveal that the year wise growth of literature in terms of year wise growth in the number of publications, subject areas leading to maximum publications, international affiliations, relative growth rate, doubling time and the individual contributions of authors to name a few and their publication reveals that Tiwari, G.N published highest number of papers 21 (3.70%), Document Wise Distribution show that the most number of documents are of the type article totaling to 395 (69.54%) publications. Foreign Countries Contribution in India shows that The United States of America (USA) has the top rate of involvement with 60 (31.91%)

USE OF SMART PHONES FOR ACADEMIC PURPOSE BY FACULTY MEMBERS OF BHARATHIAR UNIVERSITY

Purpose: To study the use of smart phones for academic purpose by faculty member of Bharathiar university. The Smartphone has become an indispensable device for effective communication and information-gathering. Aim: The study aims to assess the level of use of smart phones for academic purpose by the faculty members of Bharathiar University. Design/Methodology/Approach: Data has been collected through questionnaire from faculty members of Bharathiar University using a random sample technique. The data were analyzed using SPSS and MS Excel. Findings: The finding of the study shows that everybody uses a Smartphone. The top three reasons for using a Smartphone are communication, browsing, and academic purpose. Majority of the respondents reported that they use smart phones for reading academic papers. Overall, the significance of smart phones helps to generate and exchange information, improve the learning and assist in projects

User’s Satisfaction with Public Libraries: A Special Reference to District Central Library, Thiruvallur (Tamilnadu)

The role of public libraries in providing such goals is troublesome to contradict. Users are the most element of any library. The identification and fulfill of their needs and satisfaction are objectives any library. This paper mainly focuses on the services provided by Thiruvallur District Central Library and satisfaction level of those services from user’s perspective. It\u27s conjointly facilitated the way to perform duties and serving the most effective doable way to satisfy their valuable users attaining their satisfaction level and by decreasing the world organization satisfactory parts of library. The study so simple a descriptive Survey and applied sampling technique over three hundred users of the library. The form used as a tool to gather data and 250 questionnaires were received from respondents out of 300 questionnaires distributed. It had been discovered by the study that the library is taking part in the main role at some extent. However several areas must be revised to fulfill the expectation and intellectual wants of society

EXPERIMENTAL EVALUATION OF THE ANTI-ULCER ACTIVITY OF GRAPE (VITIS VINIFERA) SEED EXTRACT IN WISTAR ALBINO RATS AGAINST HYDROCHLORIC ACID – ETHANOL INDUCED ULCER MODEL

Background:Herbal products are finding increasing demand in the treatment of Peptic ulcer, on account of their better safety and efficacy.Objectives:To evaluate the anti-ulcer activity of ethanolic extract of seeds of Vitis Vinifera in Wistar albino rats.Methods:The ethanolic extract of Vitis Vinifera was investigated for its anti-ulcer activity in rats against HCl – Ethanol induced ulcer model. The antiulcer activity was assessed by determining and comparing gastric volume, pH, free and total acidity; ulcer number and its inhibition, ulcer severity and ulcer index.Results:A significant antiulcer activity was observed. The grape seed 100mg/kg group showed significant [p < 0.05] reduction in ulcer number 30.00 ± 3.23 as compared to the control. The grape seed 200mg/kg showed significant [p < 0.05] reduction in ulcer number 27.33 ± 2.97, free acidity 20.00 ± 2.26, and gastric lesion18.00 ± 2.96 as compared to the control.Conclusion:This present study indicates that Vitis vinifera seed extract has potential anti ulcer activity in the model tested. Keywords: Vitis vinifera, Anti-ulcer, Ethanol, Free acidity, Total acidit

EMISSION DUE TO MOTOR GASOLINE FUEL IN RECIPROCATING LYCOMING O-320 ENGINE IN COMPARISON TO AVIATION GASOLINE FUEL

Piston-powered aircrafts rely on 100 low lead (100LL) Aviation Gasoline (AVGAS) for safe operation. AVGAS has high levels of Tetraethyl Lead (TEL). TEL is an additive which is added in aviation fuels to assist in anti-knocking. The main reason for continuation of TEL as an additive in AVGAS is because aircraft engines are prone to engines knock when operate at higher power settings and temperatures. TetraEthyl Lead (TEL) or Plumbum (Pb), which is the additive of AVGAS, for octane boosting and valve recession avoidance, can cause serious health impacts. One of the possible technique to eliminate the effect of Pb emissions caused by general aviation was to make unleaded Motor Gasoline (MOGAS) accessible as another option to leaded AVGAS for the use in reciprocating aviation engines. The unleaded MOGAS has relatively lower octane rating compared to leaded AVGAS. Due to knocking and engine parameter performance, utilization of a fuel with too low of an octane rating is a risk. Besides, numerous gasses are produced as by product of combustion as a result of emission from aviation engines. In this study, a full scale engine emission due to locally available unleaded MOGAS fuels are determined and compared to the typical leaded AVGAS used. This ground level emission tests are performed by evaluating different fuels on emissions from a full scale Lycoming O-320-B2A reciprocating engine. The fuels to be tested in this study are 100 LL AVGAS, RON100 MOGAS, RON97 MOGAS, and RON95 MOGAS. Each of this fuel is tested at a time in Lycoming O-320-B2A reciprocating engine and the data for emission of of exhaust gases CO, NOx and HC, were measured by an emission analyser (EMS 5002) and recorded. Although the emission of both AVGAS and MOGAS are moreover the same it is expected that that MOGAS burns cleanly and minimal combustion chamber deposits are produced in the engine
