in this paper we introduce the concept of weakly prime ternary subsemimodules of a ternary semimodule over a ternary semiring and obtain some characterizations of weakly prime ternary subsemimodules. we prove that if $n$ is a weakly prime subtractive ternary subsemimodule of a ternary $r$-semimodule $m$, then either $n$ is a prime ternary subsemimodule or $(n : m)(n : m)n = 0$. if $n$ is a $q$-...

Densities , viscosities and ultrasonic velocities has been measured for the ternary mixture involving morpholine(1) + cyclohexanone(2) + 1hexanol(3) at 308.15K and 318.15K over the entire range of mole fraction. Parameters like excess volume, adiabatic compressibility, free volume, linear free energy, acoustic impedance, relative association and isentropic compressibility were calculated. From ...

The normal mode analysis of the light scattered by a ternary mixture is presented. The treatment is based upon a method, previously formulated by the authors, which is valid under conditions for which the sound modes are decoupled from the modes associated with heat and mass diffusion. The expressions obtained for both the lorentzian and non-lorentzian contributions to the Brillouin peaks are s...

Bacterial endotoxins have strong affinity for metallic biomaterials because of surface energy effects. Conventional depyrogenation methods may not eradicate endotoxins and may compromise biological properties and functionality of metallic instruments and implants. We evaluated the solubilization and removal of E. coli endotoxin from smooth and porous titanium (Ti) surfaces and stainless steel l...

Batch distillation in a column with a middle vessel can avoid many of the disadvantages associated with the regular batch distillation processes. In this paper we present an experimental investigation of the separation of a zeotropic ternary mixture via total reflux operation and of the separation of an azeotropic binary mixture via batchwise extractive distillation. Moreover, the results obtai...

Thin-layer chromatography of α-amino acids has been performed on layers prepared from a 1:4 stannic arsenate–cellulose mixture. RF values of the amino acids were determined after development with a variety of mobile phases. Important synthetic ternary separations have been achieved on the basis of different RF values. Lysine and threonine have been selectively separated and quantitatively deter...

Thermal diffusion coefficients in three ternary mixtures are measured in a thermogravitational column. One of the mixtures consists of one normal alkane and two aromatics (dodecane-isobutylbenzene-tetrahydronaphthalene), and the other two consist of two normal alkanes and one aromatic (octane-decane-1-methylnaphthalene). This is the first report of measured thermal diffusion coefficients (for a...

In this work, we determined thermophysical properties such as electrical conductivity and refractive index for 1-propyl-3-methylimidazolium bromide, [PrMIm]Br in ternary mixtures of [PrMIm]Br + ethylene carbonate + water at T = (298.2, 308.2 and 318.2) K and 0.1MPa. Conductometric measurements were carried out for [PrMIm]Br ionic liquid in ethylene carbonate + water solvent mixture in various c...

this publication uses a colorimetric method based on the absorbance spectra of dye solutions to improve on beer’s law when calculating the dye concentrations of a three-component mixture. the performance of the new method is compared with that of beer’s law evaluated at three wavelengths, and beer’s law evaluated at 16 wavelengths. colorimetric method gives the best prediction of dye concentrat...
