Voltage and current data that are directly obtained from the tests are processed with Microsoft Excel.
Because of the rate oxidation and the rate of reduction are equal then this line equation is equivalent.
The Result of Polarization The resulting data is processed using auto lab and the NOVA 1.8 program.
The results of the processed data display a graph of the current value for each potential change, then expressed in the form of an E / Log curve i.

Anaerobic digestion process for reduction of the pollution in palm oil mill effluent (POME) is advantageous before POME is released to the environment.
Kinetics calculation: Kinetics parameters corresponding to the biohydrogen production were calculated from the cumulative hydrogen production versus time data.
The cumulative hydrogen production versus time data was fitted with modified Gompertz equation (Eq.1) [8] to determine the hydrogen production potential (Hmax,v), hydrogen production rate (Rmax,v) and lag phase ().
Each data point represents average value of duplicate experiment (n=2) and I-bar represents standard deviation.

Introduction Statistical data show that in Europe and America, the market demand for biodegradable plastic is 40,000 - 50,000 and 70,000-80,000 ton/year and expands to 20 and 16% per year, respectively.
Data Analysis Data were analyzed by Duncan's Multiple Range Test (P≤0.05) using the SPSS software program version 10.0.

After annealing at 970K for 1 hour, the X-ray diffraction data indicated the formation of Ti5Si3 alongside with NiSi and Ni3Ti (see Fig. 2a).
From data of X-ray diffraction, we found that the annealing at 870K for 8 hours did not cause essential changes of their phase structure.
Results of resistivity measurement have confirmed the phase changes discussed in the above (Fig. 3). 0 2 4 6 8 10 12 14 16 18 20 270K 670K,1h 870K,1h 1070K,1h 1070K,2h 1270K,1h Annealing Specific resistance, µµµµΩΩΩΩ-cm Fig. 3 Change of electrical resistivity of 200 nm Ti/200 nm Ni/(001)Si after annealing After annealing at 870K the samples showed a sharp reduction of electrical resistance, which can be explained by the formation of NiSi.
These data testify that the thermal stability of NiSi phase formed in the ternary system of Ti/Ni/Si as studied here, is better than the NiSi formed in the binary system of Ni/Si.

Single and double-ring type bone fasteners were developed based on analysis of the computerized tomography (CT) transverse section data of human bones.
The safety and effectiveness of this bone fastener system were evaluated by analysis of follow-up data.
The reduction in temperature initiated a conversion into a martensitic phase state.
There is currently no published data demonstrating that the use of this TiNi SMA in the human body has any negative effect, and several medical devices used as permanent implant have been approved for their safety and efficacy and now on the market.

The highest frequency data could be used to calculate ρ, σ andτ.
The NI USB-6251, a high performance data acquisition instrument (DAQ), was used to collect the measured data at a rate of 1000 samples per second.
However, P-DVFS_60 could get better energy consumption because of the significant power consumption reduction in heavy memory-intensive benchmarks.

It is quite sensitive, but the data window is too long to the traveling wave protection. [5] just analyzes the induced lightning regardless of the direct lightning. [6] takes advantages of the changing trends of zero-mode fault voltage in a period of time to identify shielding and back striking lightning.
From analyses of the waveform above, it can be seen that the lightning current waveform is shaking because of the constant reduction of the catadioptric lightning current and the little damped coefficient of the transmission line system.
