Biswas et al. (1993. A model for chlorine concentration decay in pipes. Water Res. 27(12), 1715-1724) presented an analytical solution of a two-dimensional (2-D) steady-state chlorine transport equation in a pipe under the turbulent condition and employed fractional error function and regression technique to develop an approximate solution. However, their approximate solution may not give a goo...

DNA computing is the method for computation by using DNA and its chemical reactions. Adleman and Lipton have shown that an instance of NP-complete problems can be solved by DNA computing [1, 2]. Their methods first generate all candidate solutions in parallel, and then extract target DNAs by some chemical operations. However, such a simple approach to combinatorial problems will be unpromising,...

The solubility values determined by voltammetry have been overestimated because of adsorption on electrodes...

We have performed small-angle Rayleigh light-scattering measurements in polymer solutions under various externally applied temperature gradients. Our experiments confirm the existence of an enhancement of the concentration fluctuations. The nonequilibrium concentration fluctuations are proportional to s=Td2yk4, where =T is the applied temperature gradient, and k is the wave number of the fluctu...

This paper proposed a fractional model for the flow rate and characteristic of the impurity of order α, β(0<α, β≤1) respectively, which describes one dimensional dynamical flows of electrically conducting fluid. In this model fractional derivatives are described in the Caputo sense. The beauty of the paper is residual analysis which shows that our approximate solution converges very rapidly to ...

AUophane, haUoysite, kaolinite, and in particular, Mg-rich montmorfllonite, biotite, and vermiculite of clay size, are destroyed in 24-48 hr at room temperature. A salt-free, NH4-saturated sample, weighing 80 mg, is shaken in 80 ml o...
