Conventional hydrocarbon oil cannot adhere effectively to oxidized coal, resulting in a low yield of clean coal. In this study, high-speed homogenizer was used emulsify LDD (laurylamine dipropylene diamine) and kerosene, which enhanced the flotation efficiency The results showed an increase from 4.12% (only kerosene) 23.33% (emulsified oil). An contact angle indicated that mixture reagent can h...

This paper presents an investigation on the tribological properties of zinc borate ultrafine powder (ZBUP) employed as a lubricant additive in sunflower oil. The stable dispersions of 0.5 wt%, 1 wt% and 2 wt% ZBUP in sunflower oil were achieved by using an ultrasonic homogenizer. Both a 4-ball tester and a pin-on-disc tester were employed to evaluate the antiwear and friction reduction capabili...

SUMMARY A method for cytochemical fractionation of the Lettré-Ehrlich ascites tumor has been presented. The cells were exposed to dilute Ringer solution which increased the cell size and rigidity and allowed them to be homogenized in 0.44 M sucrose with the use of the Dounce all-glass "ball and cylinder" homogenizer. Nuclear, mitochondrial, and microsome + "soluble" fractions were obtained and...

Abstract. Spatially heterogeneous Earth radiance scenes affect the atmospheric composition measurements of high-resolution observation spectrometer missions. The scene heterogeneity creates a pseudo-random deformation instrument spectral response function (ISRF). ISRF is direct link between forward radiative transfer model, used to retrieve state, and spectra measured by instrument. Hence, dist...
