It is, then, necessary to detect N-related recombination centers by various investigating methods and to accumulate experimental data for more detailed discussion.

Data have been grouped by Ge target concentrations.
While the N-doping concentration increase leads to a reduction of the forward voltage drop VF and of the blocking voltage VBR of the MPS diodes, no significant impact of the Germanium co-doping can be observed.

Economical Aspect
Based on Table 1 data, an economical justification is done to proof the amount of energy and money that can be saved by the industries by using the in house rotor.
So the amount of money that is saved for new rotor is RM4.5 million compared to the existing rotor that is just RM542, 000.This amount is nearly eight times than what new rotor bar can save and this also shows that new rotor which has 0.35mm and 10mm rotor bar size bars has better performance in terms of efficiency, losses reduction, annual energy saving (AES) and total cost saving (TCS).Through research is still needed to justify these losses.

SF260 is the poly silicon fluorine thinning agent and its main effect is viscosity reduction.
Table 1 Heat endurance contrast data table of the organo-sillica system after the content of GWJ is increased Formula number of drilling fluid PV/[cp] YP/[Pa] YP/PV API filter loss 1# Before hot roll After hot roll 50 29 29 13 0.25 3.5 2# Before hot roll After hot roll 43 25 22 8 0.32 3.8 It can be seen from Table 1 that YP and PV of the system get lower when the content of GWJ is increased from 0.5% to 1.0%.

Although comparisons between the numerical[5,6,9,11] and experimental[3] results showed some similarities, it may be doubted as the assumed input data for calculations were quite different from the experimental ones.
The reduction of filmthickness may possibly lead to a lubrication failure.

The transmission data have been used for evaluating the band-gap energy value of the ZnO films.
The decrease in band gap of ZnO films may be attributed to the improvement in the crystalline quality of the films along with reduction in porosity and increase of grain size [4].

Plasma effects lead to the wetting angle reduction of the polymer material as by a polar (water) and a nonpolar (glycerol) liquid.
The data in Table 2 shows an increasing of PLLA films surface free energy and PCL up to 60 sec with increasing of modification time (Table 2, Fig. 3).

Thanks to the conducted studies of the granulometric composition of the coke dry mix the proximity of the data obtained on the pitch coke of the brand Electrode Pitch Coke-1 and the brand Electrode Pitch Coke-2 was noted.
In this regard, it should be emphasized that the use of petroleum coke in the production of the anode paste will lead to a decrease in its consumption during the process of alumina-cryolite melts electrolysis, to a reduction in the cost of maintenance of electrolyte pots and to an increase of the main technical-and-economic indices of the process of alumina-cryolite melts electrolysis.
