The expansion of gas-fluidised beds has been examined in the range of Archimedes number from 100 to 105 using five grades of glass ballotini and two grades of lead shot of narrow size distribution, and Diakon particles of wide size distribution.
If you want to use two grades of fuel simultaneously use the large size grade at the bottom and then the small size fuel at the top, see that this small size fuel simply does not slip downwards while burning.
The scoring of stained section was performed using four grades related to proportion of positive tumor cells: 0: 0%; 1: 1 to 10%; 2: 11 to 50%; 3: > 50%.
We defined immunohistochemical intensities of normal type II epithelial cells as positive; "+", and expressed those of each area using five grades: "-", none; "±", more or less; "+", positive; "++", more intense; and "+++", very intense.
This composite column system has recently been developed by the author as a special form of double-skin tubular columns (DSTCs), with the column manufactured using two different grades of concrete (referred to as dual-grade concrete (DGC) DSTCs in this paper).
The RIFLE classifications we used defined three grades of increasing AKI severity, including R (risk for kidney injury), I (injury to the kidney) and F (failure of kidney function) [ 8].
Several PA 6/halloysite composites with 0 wt% to 30 wt% filler loading using two different grades of PA 6 were prepared.
Concrete cylinders that were prepared using two different grades of concrete, namely normal-strength concrete (NSC) and HSC, were confined with Nitinol (Ni-Ti) SMA spirals having a pitch spacing of 36 and 20 mm, respectively.
The effect of organically modified clay on the morphology, phase stability and mechanical properties of polypropylene (PP) and polystyrene (PS) blends was studied using three molecular weight grades of PP.
