Spectrophotometric studies are presented of the glycylglytine-copper(I1) [GG-Cu(II)] system in aqueous solution under conditions in which the ligand is present in great excess (up to 1000: 1). In highly basic solution (pH 12 to 13) the spectral absorption maximum changes with increasing ligand concentration from 640 to 540 rnp. The spectral data are interpreted in terms of an equilibrium betwee...

In this paper we prove the existence of all moments of the solutions to the time-dependent spatially homogeneous transport equation describing elastic and inelastic scattering of particles. The proof uses the theory of resolvent positive operators and Desch’s perturbation theorem. As an application we carry out the asymptotic analysis of the full transport equation with dominant elastic scatter...

Dielectrophoresis (DEP) is a popular technique for fabricating carbon nanotube (CNT) devices. The electric current passing through the solution during DEP creates a temperature gradient, which results in electrothermal fluid flow because of the presence of the electric field. CNT solutions prepared with various methods can have different conductivities and the motion of the solution because of ...

serovars of lisreria l1iollocyrogelles were determined. sera of aborted samples (200) were collected from different hospitals in tehran and were tested serologically by immunofluorescent antibody methods (if tests). 137 positive sera were identified. positive sera were tested against 12 serovars of listeria l1iollocytogelles separately. titers of antibody in patients' sera for all serovars...

By the use of a tiny pressure-transferring probe and capacitor-type sensor, the dynamic pressure signals in the jet flow of the rapid expansion of supercritical carbon dioxide are measured, which distinctively shows the characteristics of quasi-periodical coherent structures. After Fast Fourier Transform (FFT) conversion of the time series signals of the dynamic pressure, there exist three domi...
