Journal of Medical and Allied Sciences , 2012,
Abstract: The development of an anthropometric craniofacial data base is a necessary multidisciplinary initiative, and on anthropometry of the South-Indian face is inadequate. The purpose of this investigation is to obtain average parameters that define the soft tissue facial profile of the investigated population in order to provide an important reference for community, security, social and medical applications. In this pilot study, the faces of 40 young adults were studied with standardized photography and measurements, and the data collated to determine averages for the Deccan region ethnic sub-set. This data-set has been compared and contrasted with others in literature.

Abstract: Research is essential for expansion and diversification of any subject field. The scope of any sub-ject will be determined by the quality of research it produces. Not only this, research is also vital to be undertaken for survival and sustenance of the existing subject. Usually the research activities are undertaken for the welfare and betterment of living especially for humans. Library and Information research has always been the ultimate vision of academicians and intellectuals as it directly or indirectly influences research in other fields whether scientific, technical, social or otherwise. In the present study attempt has been made to have an analysis of Library and Information Science literature produced in four nations—Britain (United Kingdom), Russia (Russian Federation), India, China (BRIC). The current study is conceived to assess the quantitative aspect of research output scenario of BRIC nations for the period of last seventeen years i.e. 1996-2012 in the discipline of Library and Information Science (LIS). To undertake the study, data was retrieved from SJR—SCImago Journal & Country Rank on July 22, 2014, from http://www.scimagojr.com and the analysis is being undertaken on those documents/publications only identified on this particular databank. The study is undertaken with the view to evaluate and assess the general publication trend of Library Science in BRIC nations. Study of the related literature has also been undertaken briefly so as to develop better perception of the concept and thereby help in the furtherance of scope of the study.

Abstract: : This article argues the importance of the reading programme as the pivotal issue inthe lexicographic process. It is essentially a practical article which outlines strategies for developingand implementing a reading programme for monolingual lexicography. The arguments are informedby theory, together with an examination of the data-collection procedures followed by theDictionary Unit for South African English (DSAE) and a survey of current practice in major Englishdictionary units around the world, namely the Oxford English Dictionary, the Canadian OxfordDictionary, the Australian National Dictionary Centre and the New Zealand Dictionary Centre.The reading programme for the DSAE is first defined and contextualized within its mission statement.The article then explores the challenges inherent in sampling contemporary written and spokenEnglish in the South African multilingual context. It is intended to inform the DSAE's intakepolicy, in terms of the following critical issues: — the definition of South African English, — the monitoring and selection of print, oral and electronic sources, — the excerpting of citations and relevant bibliographic information, and — the recruiting and training of readers. These interlinked aspects of the reading programme have crucial implications for the quality andauthority of the monolingual dictionary on historical principles.

Abstract: The stem bark of Acacia nilotica is used as a powerful astringent and the decoction is used as gargle for throat troubles and stomatitis.q3 Bark contains several polyphenols such as catechin,epicatechin, dicatechin, quercetin and tannin. Gallic acid has been reported to have antidiabetic,antithrombotic, anti inflammatory and anticarcinogenic activities. A simple, precise and accuratehigh-performance thin layer chromatographic method has been established for the determination of Gallic acid in the bark powder of Acacia nilotica Linn. The acetone extract of the bark powder wasused for the experimental work. Separation was performed on Silica gel 60 F254 HPTLC plates with Toluene: Ethyl acetate: Formic acid (6:4:0.8 v/v), as mobile phase. The plate was scanned in the densitometric absorbance mode at 280 nm. Gallic acid response was linear over the range 2-7 μg ml-1. The HPTLC method was validated in terms of sensitivity, accuracy, precision and reproducibility. The concentration of gallic acid in the bark powder was found to be 0.86%.

Checking Temporal Properties of Presburger Counter Systems using Reachability Analysis
K Vasanta Lakshmi,Aravind Acharya,Raghavan Komondoor
Computer Science , 2013,
Abstract: Counter systems are a well-known and powerful modeling notation for specifying infinite-state systems. In this paper we target the problem of checking temporal properties of counter systems. We first focus on checking liveness properties only, and propose two semi decision techniques for these properties. Both these techniques return a formula that encodes the set of reachable states of a given system that satisfy a given liveness property. A novel aspect of our techniques is that they use reachability analysis techniques, which are well studied in the literature, as black boxes, and are hence able to compute precise answers on a much wider class of systems than previous approaches for the same problem. Secondly, they compute their results by iterative expansion or contraction, and hence permit an approximate solution to be obtained at any point. We state the formal properties of our techniques, and also provide experimental results using standard benchmarks to show the usefulness of our approaches. Finally, we provide a technique for checking arbitrary CTL temporal properties, which use the liveness property checking techniques mentioned above as black boxes.
Tapping the unexploited plant resources for the synthesis of silver nanoparticles
A Leela, M Vivekanandan
African Journal of Biotechnology , 2008,
Abstract: Development of biologically inspired experimental processes for the synthesis of nanoparticles is evolving into an important branch of nanotechnology. The bioreduction behaviour of various plant leaf extracts such as Helianthus annus (Asteraceae), Basella alba (Basellaceae), Oryza sativa, Saccharum officinarum, Sorghum bicolour and Zea mays (Poaceae) in the synthesis of silver nanoparticles was investigated employing UV/Visible spectrophotometry, XRD (X-ray diffraction) and SEM (Scanning Electron Microscopy). H. annus was found to exhibit strong potential for rapid reduction of silver ions. It was observed that there is no correlation always between the colour development and the increase in absorbance exhibited by the nanometal synthesised. The work adds to the confirmation of previous reports on biosynthesis of nanometals using plant leaf extracts.

Abstract: TLC densitometric method for quantification of gallic acid, quercetin and lupeol using HPTLC is developed. This is the first report of quantification of these three bioactive compounds viz Gallic acid, quercetin and lupeol using HPTLC from this plant. Quantification of gallic acid and quercetin was carried out from the methanolic extract using the solvent system of Toluene: Ethyl acetate: Formic acid (6:4:0.8 v/v/v). Lupeol was quantified from chloroform extract using the solvent system of Toluene: Ethyl acetate (7:3 v/v). The Rf values of gallic acid, quercetin and lupeol are 0.22, 0.37 and 0.70 respectively. The linearity ranges for gallic acid (100 to 600ng), quercetin (2000 to 7000ng) and lupeol (100 to 1200ng) with correlation coefficients (r-values) of 0.99968, 0.99708, 0.99971 respectively. The amount of gallic acid, quercetin and lupeol was 124.31, 580.4, 24.89 μg/ml respectively. Quantification of gallic acid, quercetin and lupeol showed good resolution and separation from other constituents of extract. Its main advantages are its simplicity, accuracy, and selectivity. This method can also be used for the estimation of these compounds in other herbal preparations and may be useful for standardization purposes.
Dialogue with Citizens - the Missing Link in Delivering e-Government?
Wendy Olphert,Leela Damodaran
Journal of Systemics, Cybernetics and Informatics , 2005,
Abstract: Many governments and political bodies across the globe are exploring the potential benefits of ICT as a means of improving communication with citizens and stimulating participation and engagement in political and civic processes. This paper reviews progress to date in the UK towards delivering e-government at the local level, and concludes that that there is evidence of a lack of 'pull-through' of the ministerial concepts and vision in the current delivery of e-government. In order to achieve the important e-government goals of increasing citizen participation and improved speed and efficiency of the underlying processes, the authors argue that a participative approach to the design and delivery of e-government is required. A co-creation approach to design is proposed. This will enable a dialogue between the citizen and the local authority, and which will embody and support democratic processes which will facilitate the genuine co-creation of decisions.
