Introduction In comparison to other grains, rice is one of the most significant food crops in Malaysian culture.
Germination [%]=Number of seed germinatedNumber of total seeds tested×100% (1) Vigor index=Germination ×Seedling length (shoot length+root length) (2) Fourier Transform Infrared (FTIR) Spectroscopy.
The starch shape changes after neutron irradiation with 14 Gy in PTS and 35Gy in BP, becoming more spherical, shrinking and showing partial aggregation. [19] discovered that the number of small-size granules increased in both inner and outer layer endosperm of rice grain treated with 2 KGy of gamma irradiation.

The higher cooling rates during the quenching process will form smaller grain sizes, improving the hardness and strength of steel, but toughness and ductility are decreased [1].
At a high-temperature tempering of 600oC, the microstructure changes from martensitic to tempered martensitic and ferrite grain.
The greater the number of dissolved carbides in the oxide dispersion strengthened steel matrix as a solid solution will generate higher hardness [9].
This research suggests that the more brittle surface will decrease the elasticity – a reduced number of cycles characterizes this phenomenon.

The fracture surfaces of specimens that failed after fewer cycles showed mainly precipitates and micro voids, whereas specimens that fractured after a higher number of cycles indicated that cracks initiated at the surface.
An important feature of this micrograph is elongated grains as a result of rolling.

The amount and number density of ε martensite are increased with an increase in Co content, resulting in the improvement of damping capacity.
The grain size of γ austenite in each alloy was adjusted to 120µm by changing the solution treatment time, to exclude its effects on martensitic transformation behavior and resulting microstructure.
Fig. 4 shows the variation in relative numbers of ε martensite plates in unit area with ε martensite content, where the number of ε martensite plates for the Fe-23%Mn-2%Si alloy air-cooled at 298K, was regarded as a standard value.
Change in relative number of ε martensite plates with ε martensite content for experimental alloys.
The addition of Si is detrimental to the amount and number density of ε martensite, resulting in the decay of damping capacity.

If it is present near the interphase, long grains are found to cover almost the whole phase layer.
This is found in most of the cases since the nucleation barrier for new grains to form must be high.
A focused area around this marker plane is shown in which different grain morphologies around K2 is clear.
The number of interdiffusion coefficients to be estimated depends on the number of components in a system.
Moreover, the number of precipitates of bigger sizes decreases.

OPMFS pulp recorded value of 6.42 s, 353 ml, 76.5 %, 36.7 % and 9.35 for drainage time, freeness, moisture content, screened yield percentage and Kappa number respectively.
Then, the fibres were sieved by using chip classifier machine to remove the smallest pollen grain of the spikes.
KAPPA number of the pulp was determined according to TAPPI T236 “Kappa Number of Pulp.

The execution efficiency got improved much more based on increasing the number of processor core and thread number executing parallel via using multithread parallel execution technology.
Their work made the sort performance improved to a greater extent via breaking down the sort task into independent computing tasks and digging the fine-grained parallelism of sort algorithms.
Suppose the length of the unsorted sequence is n and the number of parallel thread that will be executed is TNUM it can be deduced that the number of trip needed for two-way merge sort is .
For the ith trip the number of merge should be /2 as the length of the merge segment is 2i and the number of comparison and movement should be 2i removing the tail part merge.
We also can see it is that the efficiency will be improved the best when the number of parallel thread is 4 as it is just equal to the number of core.

Number of neurons is the dimension of study sample vector, namely 6
Number of neurons equals the number of input layer learning samples.
Number of neurons is the dimension of output vector in the learning sample.
According to the fitness function to calculate the fitness value, the speed of the grain is, individual extremum is, population global extremum.

The paper adopted Z-axis as rotation axis of the pump, utilized Pro/E software to process three dimensional model, adopting unstructured grid numbered 310868,as figure 1 shows that.
The grain density is 2600 kG/m3.
TO cut down on the length of paper, the follow only provided the simulate result for particle size is 1mm and 12mm under volume fraction numbered 0.2.
As the four figure shows from figure 2 to figure 5, the paper draws some conclusions as follow: 1)For large particles, they mainly distribute in the field near impeller hub and middle impeller passage, their number are more than that near the cover field.
