Colour of Celestine

Combination of Colour Favoured and Colour

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

Colour Emotion Models, CIELAB Colour Coordinates, and Iranian Emotional Responses

Ten colour emotional scales, namely, "Warm Cool", "Active-Passive", "Like-Dislike", "Clean-Dirty", "Fresh-Stale", "Modern-Classical", "Heavy-Light", "Hard- Soft", "Tense-Relaxed", and "Masculine-Feminine"are investigated for single-colour stimuli in CIELAB colour space within a psychophysical experiment by forty observers. The relationships between Iranian colour emotional responses and CIELAB ...

Interaction of Celestine Concentrate and Reagent Grade SrSO4 with Oxalate Solutions

The interaction of reagent grade strontium sulphate and celestine concentrate with aqueous solutions of oxalic acid, sodium oxalate and ammonium oxalate for the production of strontium carbonate were investigated for different oxalate compound:SrSO4 mole ratios and reaction times using x-ray diffraction analysis and dissolution tests. Under the same experimental conditions, it was found that aq...
