Milled rice from a laboratory mill and a commercial–scale mill was evaluated for head rice yield using a shaker table and a machine–vision system called the GrainCheck. Comparisons were made for both medium– and long–grain rice varieties. For each variety, samples with different levels of broken kernels were analyzed to determine the performance of the two instruments over a range of head rice ...

The treatment of olive mill waste water was studied on the laboratory scale. Physico-chemical analyses showed the final products had a mean pH of 5.4 without neutralisation and 5.7 when lime was added to the process. Raising the pH by adding lime had a positive outcome on the degradation of phenols, whose levels were reduced by over 76%. The lime also changed the structure of the organic matter...

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...

The International Rice Research Institute (IRRI) Test Tube Mill and the Kett ”Pearlest” Polisher were evaluated in terms of milling performance in comparison with a McGill No. 2 Mill. Degree of milling (DOM), evaluated in terms of percent bran removal (the percentage of weight lost during milling) from brown rice, and whole kernel yield (WKY) were compared using sample lots of medium– and long–...

Healthy men produce an enormous number of sperms, far more than necessary for conception. However, several studies suggest that semen samples where the concentration of sperms is below 40 mill/mL may be associated with longer time to pregnancy or even subfertility, and specimens where the concentration of sperms is below 15 mill/mL may carry a high risk of infertility. Historic data from the 19...

on to a heavy wooden mill which is revolved by the bulls moving in a circle round the mill. The old man was bending over the crushing blocks to remove sugar-cane debris when his long hair got undone and was caught in the mill. The bulls continued to move round in a circle which resulted in his hair being wound into the mill. He was dragged round the mill and fruitlessly tugged to get free. His ...

Ball mill is vital equipment in industries viz. mineral dressing, ore processing, fertilizers, food and diary, pharmaceuticals and many others. The present work involves a meticulous study of the effect of the various parameters on the performance of a ball mill. The parameters studied in this work are particle size, number of balls, time of grinding, particle density, and speed of the ball mil...

Neuromodulation is well known to provide plasticity in pattern generating circuits, but few details are available concerning modulation of motor pattern coordination. We are using the crustacean stomatogastric nervous system to examine how co-expressed rhythms are modulated to regulate frequency and maintain coordination. The system produces two related motor patterns, the gastric mill rhythm t...

Several samples of evaporator scale collected during the 1993 and 1994 milling seasons were analysed using x-ray diffraction, x-ray fluorescence, scanning electron microscopy and optical microscopy. The results were evaluated in terms ofcurrent knowledgeofevaporator foulingand similar trends were found to those published in the literature. From these results, typical evaporator scale profiles c...
