Electrochemical analysis of sweat using soft bioelectronics on human skin provides a new route for noninvasive glucose monitoring without painful blood collection. However, sweat-based glucose sensing still faces many challenges, such as difficulty in sweat collection, activity variation of glucose oxidase due to lactic acid secretion and ambient(More)
Sediment from the Anacostia River (Washington, DC, USA) was suspended in aerobic artificial river water for 14 d to investigate the dynamics of dissolved metals release and related parameters including pH, acid volatile sulfides (AVS), and dissolved/solid phase Fe(2+). To better understand and predict the underlying processes, a mathematical model is(More)
The effects of dynamic changes in pH and salinity on metal speciation and release are investigated with sediments posed in a simulated estuarine environment. The release of Zn, Cd, Mn, and Fe was studied using sediment from the Anacostia River (Washington, DC, USA) spiked with freshly precipitated amorphous cadmium sulfide to increase Cd content. The(More)
Concentrations of total mercury (Hg) and selenium (Se) were determined in diet fish and whole blood and tissue samples from seven bottlenose dolphins (Tursiops truncatus) housed at the National Aquarium Baltimore (NAB). In addition, concentrations of monomethylmercury (CH(3)Hg(+)) were determined in diet fish and dolphins' tissue samples. The data were(More)
Until now the complete mitochondrial genome (mitogenome) sequences of only three species of clitellate have been available. We have determined the complete mitogenome sequences of the elusive Burmese giant earthworm Tonoscolex birmanicus (Clitellata: Megascolecidae), which is endemic to Myanmar. The 15,170-bp long genome contains the 37 genes typical of(More)
McCoy proved that for a right ideal A of S = R[x1, . . . ,xk] over a ring R, if rS(A) = 0 then rR(A) = 0. We extend the result to the Ore extensions, the skew monoid rings and the skew power series rings over non-commutative rings and so on. 2000 MSC: Primary: 16S36, 16N60; Secondary: 13B25, 16W20. Over a commutative ring R, McCoy [4, Theorem 2] obtained(More)
A diffusive gradient in thin films (DGT) is an in situ sampling technique for the quantitative analysis of contaminant concentrations that is based on the diffusion and adsorption of contaminants on to resin gels. In the present study, a DGT technique was applied to measure total mercury (Hg) and monomethylmercury (MMHg) concentrations in lake and coastal(More)
To date, a very limited number of complete clitellate mitochondrial genome (mitogenome) sequences are available. Therefore, in the present study, we elucidated the complete mitogenome sequence of Amynthas jiriensis (Clitellata: Megascolecidae), a species endemic to South Korea. Its 15 151-bp-long genome contains the 37 genes typical of metazoan mitogenomes(More)
