Bioremediation of landfill gas using methanotrophic microorganisms / Jayanthi Barasarathi
No full textMethane (CH4) is an important greenhouse gas with a global warming potential 25 times higher than carbon dioxide (CO2). Landfill is a one of the major contributor to
global CH4 emission and is estimated to be 500-800 Mt CO2 eq/year. Previous studies have shown that microbial oxidation of CH4 in landfill cover soil can be enhanced
using substrates that are rich in organic matter, such as compost. Methanotrophs are group of bacteria that utilize CH4 as its sole carbon and energy source. Therefore this
study is aimed to characterize the physiochemical properties of biocover material,while identifying the potential methanotrophic bacteria from landfill cover soil. It is also intended to evaluate a comparative assessment of the CH4 efficiency of the biocover material under controlled conditions for bottle and column experiments with
the addition of potential methanotrophic bacteria. Compost has been identified as best biocover material based on the associated physiochemical properties and their ability
to oxidize 4% of CH4 within 4 days. Three types of methanotrophic bacteria were isolated from landfill soil and identified as Methylomonas sp, Methylococcus sp 1 and
Methylococcus sp 2. Methylococcus sp 1 showed the highest CH4 oxidation capacity when compared to Methylomonas sp and Methylococcus sp 2 which took only 24 hours for complete CH4 oxidation. Batch experiment with addition of individual
cultures and mixed cultures to the compost carried out at different parameters indicated higher CH4 oxidation capacity at 35˚C and 40˚C, pH 6 and at 60% v/v moisture level. Addition of Methylococcus sp 1 showed the highest CH4 oxidation activity at the rate of 8.33 X 103 μg g-1h-1 while the CH4 oxidation rate with addition of Methylomonas sp was 4.16 X 103 μg g-1h-1. Addition of Methylococcus sp 2
iii showed 75% lower activity compared to Methylococcus sp 1 and 50% lower activity compared to Methylomonas sp. Bacterial count at end of the experiment showed
highest count for Methylomonas sp and Methylococcus sp 1. Statistical analysis (P <0.05) showed significant increase in CH4 oxidation with the addition of Methylomonas sp and Methylococcus sp 1 to the compost at optimum temperature,
moisture and pH when compared to the control. Column experiment carried out with addition of potential methanotrophic bacteria to the compost at different column
height showed highest CH4 oxidation activity at 60cm with the addition of Methylomonas sp and Methylococcus sp 1 and the comparison with control also showed 50% increase in the CH4 oxidation activity. The experiment carried out at
different incubation temperature and moisture content showed highest CH4 oxidation at the temperature of 35˚C to 40˚C and 60% moisture level which are similar to batch
experiment. Kinetic studies using Michaelis Menten equation for batch experiment at optimum parameters showed highest potential CH4 oxidation rate with the addition of
Methyloccocus sp 1. Addition of methanotrophic bacteria to compost showed an enhancement and significant increase in the CH4 oxidation under optimum parameters which are also similar to tropical conditions. A biocover with 60cm column height is potentially the best height for optimal CH4 oxidation

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full textWe 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
No full textWe 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
