Rapid urbanization, better heaith care facilities, improved economic scenario and increase in the number of nuciear families with both spouses working have brought about phenomenai changes in the diet, dietary habits and activity patterns and resuited in the increased prevalence of overweight and obesity across the globe and across all stages in life particularly in children and adolescents. Predominantly over nutrition is witnessed in developed countries whereas developing countries are faced with a double burden of over nutrition and undernutrition. Evidences suggest that the causative factors are many and the need of the hour is to plan strategies to curtail the increasing prevalence through various approaches which can bring about behavioural modifications, even though may be very small.- Newspaper Citations in Scientific Publications Inde/xed in Web of Science (2001-2010)

The objective of the paper is to find out the citations of newspapers in scientific publications during 2001-2010. The study was carried out for twenty English newspapers indexed in Web of Science with 250 or more citations up to 31st December, 2015. For the present study only newspaper articles of these twenty newspapers with 2 (two) or more citations were considered. During the study period there were 4146 records (newspaper articles) with 13250 citations in different scientific publications. The citations to these news paper articles in scientific publications increased gradually from 2006 onwards. These newspaper articles were highly cited in Fordham Law Review (USA) with 160 (1.21%) citations followed by American Journal of International Law (USA) with 138 (1.04%) citations.Keywords

This research presents the microhardness variations studies related to tool pin profiles on dissimilar joints of AA7075-T651 and AA6061-T651 aluminium alloys. The weld consolidation and quality was evaluated through observations of macro and micro structure. The microhardness variations were determined in the cross-section of the weld for different rotational and welding speeds. In all the specimens where the hardness distribution was measured, the AA7075 alloy was located at the Retreating side (RS) and the AA6061 alloy was in the Advancing side (AS). The Friction stir welded materials were joined under three different tool rotational speeds (800, 900 and 1,000 rpm) and three welding speeds (90, 100 and 110 mm/min), which are the two prime joining parameters in Friction stir welding (FSW). The axial load and the tilt angle parameters are kept constant at 12kN & 0°. Three different pin profiles (Taper cylindrical threaded, Taper square threaded and Square) tools were used to consolidate the weld in which the taper cylindrical threaded tool yields higher hardness of about 114.2 HV in the stirred zone with good mixing of these two alloys.Keywords

Aluminium alloys have gathered wide acceptance in the fabrication of light weight structures requiring a high strength-to weight ratio and good corrosion resistance. Modern structural concepts demand reductions in both the weight as well as the cost of the production and fabrication of materials. Therefore welding processes have proven more attractive, and there is an urgency to study their potential. Compared to the fusion welding processes that are routinely used for joining structural aluminium alloys, friction stir welding (FSW) process, an emerging solid state joining process was invented in 1991 by TWI, in which the material that is being welded does not melt and recast. The major advantage in FSW process is that the maximum temperature reached is less than 80% of the melting temperature, i.e. the joint is performed in the solid-state and excessive micro structural degradation of the weld zone is avoided. This process uses a non-consumable tool to generate frictional heat in the abutting surfaces. The welding parameters such as tool rotational speed, welding speed, axial force etc., and tool pin profile play a major role in deciding the joint strength. This paper focuses on mechanical properties evaluation and predicting the process parameters in varying rotational and welding speeds of friction-stir welding for the dissimilar precipitation hardenable aluminium alloys ie., between 6xxx (Al-Mg-Si) and 7xxx (Al-Zn-Mg).- More the Tweets more the Citations:Do Altmetric Variables Contribute to Citations?

The present study was carried out to examine the alternative metrics variables twitter and its relationships with citation pattern for scholarly articles. This study was carried on with top 100 twitted articles for the year 2014-15 and the second set of data was specific to the “Genomic” subject domain, around 131 hot paper was identified and their twittes and citation data was studied. From the study it was found that the top tweeted articles did not have any kind of correlation with citation its ϐ value was 0.071. While the second set of data from the “Genomic” subject showed a strong positive linear correlation between the Twitter count and Citation counts its ϐ value was 0.72.Keywords

The objective of the paper is to examine the citation pattern of Byline and Dateline articles of “The Guardian” newspaper during 2001-2010. During the study period, there were 5480 records (newspaper articles) with 4101 citations to different scholarly publications indexed in Web of Science up to 31st December 2015.The highest citation of the Guardian newspaper was 1833 (44.70%) during the year 2010, followed by 1004 (24.48%) citations in the year 2009, and the lowest was 22 (0.54%) citations in the year 2001. The study found that there is a gradual increase in citing Byline newspaper articles from 2001 onwards in scholarly publications, except in the year 2004,whereas, there is a gradual increase in Dateline newspaper articles citations from 2001 onwards. The study also found that the citations do not depend on the readership of the newspaper and there is significant difference in citing the byline and dateline articles in the scholarly publications during 2001-2010.Keywords

Among the techniques of text mining, topic modeling is considered one of the emerging tools to extract or detect hidden themes that lie within a huge collection of textual data. Latent Dirichlet Allocation (LDA) is considered a popular method in the field of topic modeling. This paper deals with topic modeling from 9130 articles of Sri Lankan authors having a minimum of 5 citations downloaded from the WoS database using LDA. The LDA tuning (R package) is used in the study to take various measurements for deciding subjects in light of factual elements. The top 10 latent topics were identified, and different unique terms associated with the topics were also discussed. Health is traced as the most occurring latent topic followed by forest and solar cells. Topic-1 (100%) Contains Water-related terms, which is around 60%; Irrigation and soilrelated were 40% (1997). This first topic was prominent across the period barring 1994 and 1996. Topic 3 has gradually decreased and Topic 9 has gradually increased during the last five decades. By comparing our results to traditional scholarship by Sri Lankan authors and the evolution of scientific publication by the island nation, we have shown that topic models can emerge as a scientific alternative to conventional classification systems.Keywords
