The main contribution of this paper is to give a necessary and sufficient condition under which the Shapley value coincides with the nucleolus, the CIS value and the ENSC value in the following classes of games; airport games (Littlechild and Owen (1973)), bidder collusion games (Graham et al. (1990)) and polluted river games (Ni and Wang (2007)). Along the way, we also show the necessary and s...

The genus Diplosmittia was erected by Sæther (1981) based on Diplosmittia harrisoni from St. Lucia and St. Vincent in the British West Indies. Prior to the present study the genus comprised nine species, all except D. carinata Sæther were known only from Neotropical Region (Ashe & O'Connor, 2012). During sampling in the surroundings of a highly organic polluted river, in the National Botanical ...

Denaturing gradient gel electrophoresis (DGGE) and quantitative real-time PCR (qPCR) were successfully developed to monitor functional aoxB genes as markers of aerobic arsenite oxidizers. DGGE profiles showed a shift in the structure of the aoxB-carrying bacterial population, composed of members of the Alpha-, Beta- and Gammaproteobacteria, depending on arsenic (As) and E(h) levels in Upper Isl...

A wide range of human pharmaceuticals are present at low concentrations in freshwater systems, particularly in sections of polluted river. These compounds show high biological activity, often associated with a high stability. These characteristics imply a potential impact of these substances on aquatic biota even when present at low environmental concentrations. Low flow conditions in Mediterra...

The genus Microbacterium is composed of high GC content, Gram-positive bacteria of the phylum Acintobacteria known for their antibiotic production. Microbacterium species commonly colonize agricultural rhizospheres and more infrequently have been found to colonize and infect human tissues as well. Here we report the 3,696,310 bp draft genome (chromosome and plasmids) sequence assembled at the s...

Since ancient times, Japan has been blessed with pure, fresh water. For this reason, Japanese people believe that city water is clean and safe and do not hesitate to drink it without boiling. Drinking fresh, unboiled water has been a part of the Japanese way of life. However, in recent years, pollution of river water and groundwater has increased in this country, making that water neither clean...

Escherichia coli (E. coli) is a widely used indicator of fecal contamination in water bodies. External contact and subsequent ingestion of bacteria coming from fecal contamination can lead to harmful health effects. Since E. coli data are sometimes limited, the objective of this study is to use secondary information in the form of turbidity to improve the assessment of E. coli at unmonitored lo...

The Sinos River, in southern Brazil, is polluted by industrial discharges and untreated urban wastes. Fish genotoxicity biomarkers are valuable parameters for environmental risk assessment. In this study, we used the comet assay to detect genotoxicity due to multiple sources of pollution in the peripheral blood of a native fish species (Hyphessobrycon luetkenii). In addition, we analysed possib...

This is an Open distribution, Abstract – We studied the variability of physico-chemical parameters in water, and heavy metal contents in water and sediment over time and along the Carpathian Biała Tarnowska River (southern Poland) and related them to catchment geology, human impact and the effect of barriers as a side aspect. The river water was well oxygenated, had pH 7.7–9.5 and was character...
