Differential-algebraic equations (DAEs) arise in a variety of applications. Their analysis and numerical treatment, therefore, plays an important role in modern mathematics. The paper gives an introduction to the topics ...

The densities, r and viscosities, h of NH4Cl, NiCl2 and FeCl3 in dimethylsulfoxide were studied as a function of concentration. The partial molal volume, ( 0 v j ) of these electrolytes were evaluated. The viscosity and ...
