In this paper attempt has been made to identify the uncited publications in 'micro-electro mechanical systems (MEMS) literature which is one of the emerging field in electronics. The search term 'MEMS' was used for retrieving literatures from SCOPUS database. A total of 294573 records were identified in the field of MEMS during the period 1970-2013. Out of which, 85146 (28.90 %) records were uncited publications. The uncited paper ranges between 0.09 % and 0.72 %. It can be seen that from 1988 onwards uncitedness has been reduced below the global average and it persists till 2010. Almost 56 % of the uncited publications are from the conference proceedings. 44.56% of China publications in MEMS were uncited followed by India (31.44 %), Japan (24.40 %), and France (19.44 %). Majority of the uncited publications, are of collaborative authors besides the self-citations. Mostly more than four authors' papers were uncited. Even top author papers were also uncited. The uncitedness may be due to non-awareness of those papers in the MEMS literature.
M ucoadhesive tablets were prepared to evaluate the adhesive property of the gum obtained from seeds of Ceaselpinia pulcherrima (CP) by comparing it with carbopol, hydroxy propyl methylcellulose (HPMC), and Chitosan. Physical parameters such as bulk density, tapped density, compressibility index, and Hausner's ratio values indicate good flow, the percentage of drug content was in the range of 96.4±0.97%, and various adhesive evaluation results reveal a good mucoadhesive property. The barium sulphate loaded tablet possesses strong mucoadhesive property, which was evident from prolonged adhesion in the same location of the stomach up to a period of 10 h, whereas the duration of adhesion found to be comparatively less with other polymers. From the results of in vitro and in vivo adhesive tests and in vitro release study the test agent (Gum) appears to exhibit considerable mucoadhesive property and mean residence time values when compared with tablets of carbopol, HPMC, and Chitosan.
The present study is used to identify the pattern of publication, authorship, citations and secondary journal coverage in the hope such regularities can give an insight into the dynamics of the area under consideration. During 1999- 2012 a total of 486 papers were published by the scientists in the field of space neuroscience research. The average Number of Publications produced per year was 34.7%. The highest number of publications 70 was produced in 2010. The most productive author is Rabinovich MI and Spence C with each 6 papers dealing with space neuroscience research and 1.2% of all papers published in this research field. The highest number of publication is at USA 199 (39.9%) and lowest number of publication is at UAE 1(0.2%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
