Chemical characterization of camelina seed oil:
No full textCamelina sativa (L).Crantz also known as false flax, Dutch flax is an ancient oil seed crop that belongs to the Brassicaceae family. Camelina oil pressed from the seeds of this crop has a unique aroma.
Eighteen camelina oil samples were analyzed for fatty acid composition (13 unrefined, 2 deodorized and 3 refined samples). Eight of these samples were analyzed for unsaponifiables content, free fatty acids and volatiles and semi-volatile compounds. Seven camelina seed samples were analyzed for volatile and semi-volatile compounds as well to determine the suitability of these products in animal feed formulations.
Fatty acid composition was obtained by the trans-esterification of the triacylglycerols in the oil to their methyl esters and 21 different fatty acids with chain length from C-14 to C-24 were identified. The major fatty acids were α-linolenic, linoleic, oleic, eicosenoic and palmitic acid and three fatty acids, namely tricosanoic, pentadecanoic and heptadecanoic are being first reported here.
The unsaponifiables fraction in camelina oil samples ranged between 0.45-0.8% and 21 compounds were identified. The major compounds identified were β-sitosterol, campesterol, cholesterol, phytol, squalene and brassicasterol which accounted for 80-90% of the unsaponifiable content in camelina oil.
A total of 168 and 306 volatile and semi-volatile compounds were identified in the headspace of camelina seeds and oil respectively. Homologous series of lipid oxidation derived compounds like aldehydes, ketones, alcohols, furans and hydrocarbons dominate the aroma and favor profile of the oil and seeds. Sulfur compounds (methyl mercaptan, dimethyl sulfide, dimethyl disulfide and dimethyl trisulfide), naturally occurring 3-alkyl-2-methoxy pyrazines, terpenes, short chain free fatty acids and maillard reaction products were also identified in camelina seeds. The presence of 2-sec-butyl-3-methoxy pyrazine, aldehydes and alcohols (with green notes) and sulfur compounds like 2, 4, 5-trithiahexane and 1-butene-4-isothiocyanato in some camelina oils, may be responsible for the unique aroma of this oil.
The information from this study may potentially be used by camelina oil producers as supporting data for the chemical characteristics of the oil produced in Montana, USA. Camelina oil can serve as a good vegetable source of α-linolenic acid provided it gets the much awaited GRAS certification.M.S.Includes bibliographical references (p. 165-170)by Anusha Sampat

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Women Health in Kerala Tribe A Sociological Analysis of Muthuvan Community
No full textKoodakkadukudi has 8 hamlets. Situated in Marayoor village. 9 km away from Marayoor town. 100 women are selected following systematic random sampling out of 478 families. In order to facilitate 3 objectives. Namely the social life of Muthuvan women and the educational conditions and the health related facts. It was found that Muthuvans are not aware of the harmful effects of unsafe drinking water. Their livelihood only depend on the natural source of water namely pond and river. They have no other option and are unaware of the unsafe drinking water.90 of them make use of open area for execration and urination. This requires toilet construction in their area through government program among welfare activities from the village and self help groups. Formation of self - help groups is yet to be started.
