Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

When the crisscross baffles and logarithmic spiral baffles are placed on the bottom of the stirred tank with elliptic bottom, using CFD software FLUENT simulates the velocity field of the stirred tank with elliptic bottom and bottom baffles. Compare the velocity field of stirred tank with bottom crisscross baffle to the velocity field of stirred tank without bottom baffle and analysis the flow ...

This study investigated the effect of grinding media on fine-grinding performance in wet tumbling mill. Comparative experiments between cylpebs and ceramic balls were conducted a laboratory ball mill under various conditions, such as different total masses, surface areas, numbers. The results indicated that produce slightly smaller instantaneous breakage rate than due to their small bulk densit...

For smaller mechatronic device, especially for micro Electronic system, a micro machining is a must. However, most investigations on vibration of a mill have been limited to the traditional type mill. In this article, vibration and dynamic characteristics of a micro mill were investigated in this study. The trend towards higher precision manufacturing technology requires producing miniaturized ...

two probiotic bacteria (lb. acidophilus and b. lactis) were immobilized on the alginate coat of strawberry pieces and were added to the prepared sweet non fat dietary stirred yogurt. physico-chemical parameters namely ph value, titratable acidity and synersis along with the viability of probiotic bacteria of the samples were evaluated over the 8 days of storage at 5 ºc at 2 day intervals. a sig...

Experiments Most publications of velocity measurements in stirred tanks concern measurements in single-phase flows. An excellent review of these studies was made by Ranade and Joshi (1990a). Literature concerning velocity measurements in aerated stirred tanks is scarcer however. An overview of literature is given in Table 1. Lu and Ju (1987) used constant temperature anemometry (CTA) in order t...

The relationship between surface transfer impedance and stirred mode chamber shielding effectiveness proposed by Eicher and Boillot has been simplified. This simplified relationship was used to compare the measured stirred mode chamber shielding effectiveness of nine shielding artifacts with the shielding effectiveness of the same samples calculated from transfer impedance measurements made at ...

The hyperpolarization-activated inward cationic current (Ih) is known to regulate the rhythmicity, excitability, and synaptic transmission in heart cells and many types of neurons across a variety of species, including some pyloric and gastric mill neurons in the stomatogastric ganglion (STG) in Cancer borealis and Panulirus interruptus However, little is known about the role of Ih in regulatin...

The decision to change the status of Hagia Sophia from a museum mosque stirred up massive controversy in non-Islamic world, even extent as questioning secular nature Turkish Republic. A court issued ruling which ultimately led re conversion Istanbul's Sophia, annulling government that dates back 1934. This caused anxiety Western capitals, though it is important explore how media framed this ent...
