Then in the fourth experiment, the gas will be accommodated for a gas chromatography test to obtain a comparison of gas concentration data before and after purification using an adsorber membrane.
This likely occurs due to the evaporation of the degraded cellulose components, resulting in a reduction in hydrocarbon compounds that make the membrane surface look clearer [11].
In addition, the performance of the adsorber membrane can also be assessed based on the effectiveness resulting from the gas separation process, which in this case can be in the form of data both qualitatively and quantitatively.
Qualitative data is usually displayed in the form of visual results, including based on the results of the flame test.
According to Ritonga (2020) flame test, Qualitative data is usually displayed in the form of visual results, including based on the results of the flame test.

Electrochemical reaction occurring in the SOFC cathode is the reduction of oxygen, therefore cathode materials for SOFC have to posses many properties.
Introduction Electrochemical reaction occurring in the SOFC cathode is the reduction of oxygen as follows: (1) Air is the most practical and economical way to feed the fuel cell stack.
It can be concluded as follows: the contamination of trace impurities in air have effect on the SOFC performance; theoretical analysis of SOFC degradation was done in detail and GCI technique is considerably more effective in evaluating the electrochemical performance behavior as a function of time; further experimental data using LSM as cathode material verified the validity of the GCI measurement; electronic conductivity of cathode material plays the main role for performance degradation.

Generally, the value of η which is estimated from the Current-Voltage (I-V) data is quite high for the organic diode.
Table 1: Extracted value of η from lnI vs V plot for these three different cells without and with TiO2 and ZnO nanoparticles Sample Value of ideality factor (η) Only PSF 38.17 PSF+ ZnO 37.50 PSF+TiO2 34.59 To estimate the value of Rs the data has been fitted by the Cheung Cheung method [25-26].
The dark I-V data has been measured.
The data has been fitted by thermionic emission theory and also by the Cheung Cheung function which is basically the modification of the thermionic emission theory by inducing the effect of series resistance.
Evaluation of the experimental data shows that series resistance decreases with the lowering of trap energy in the presence of nanoparticles.

Analysis of Wind Turbine
Weibull analysis software provides the life data analysis tools necessary to analyze data from all phases of product life.
The failure of WT components are calculated based on field data by using Weibull software.
The failure distribution data is shown in the table 1.
The most common type of yaw mechanism is based on a rolling slew ring bearing with a cogged inner or outer race and pinions driven by electrical motors over high-reduction gearboxes.
The tip of blade open slightly due to the low pressure developed in the hydraulic system and it make reduction in power generation.

However, according to VNIITeploizolyatsii (Lithuania) is a "short-term" exposure does not allow for reliable data [5].
MWIM offered to consider moisture resistant, if after 1 hour of trial strength reduction does not exceed 30% [4].
The data obtained showed that between the values of strength reduction slabs samples at their endurance over boiling water and store in the desiccator in a moist air at 18-20 ° C there is a direct proportional relationship.
With less degree of polycondensation is possible receive incorrect data due to possible post cure the binder at a test temperature of about 100 ° C.
The data obtained allow us to recommend companies that manufacture MWI replace lengthy testing moisture resistance slab samples by standard methods to express control.
