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.

Their goals was to achieve a high discounts of insurances by creation of conditions for reduction of enterprise risks and by acceptance of preventive measures in relation to identified potential danger.
Control of the possible failure creation and with this connected risk, is the process of decision making for encompassment and/or reduction of risk, or realization of decision and its enforcement including repeated evaluation of consequences with the use of the results of risk appraisal as input data [3].
There are several classes or levels of criticality depending on risks and reduction of system serviceability and also on the probability of frequency [4].
Change of the concept – for elimination of fault causes or for reduction of the fault importance 2.
By the help of analysis we get the possibility to realize the prevention of these risks or their reduction.

Mathematical Model
The goal of optimal planning on capacitor in power distribution network is the installation location and compensation capacity of fixed parallel capacitor, which makes total loss reduction benefits maximum in every static period, that means power distribution network loss being minimum.
The maximum loss reduction benefits are taken as objective function during the planning period, namely
a) Input original data, taboo step is 4, the maximum iterative steps is 10 for the same continuous optimal solution.
A 34 nodes distribution system is optimized, whose data is taken from literature [7].

In ferric anaerobic leaching 46 mg of ferrous iron were dissolved corresponding to the chemical reduction of ferric iron on pyrite, 10.84 mg pyrite would be dissolved.
Fig. 2 shows that the biological reduction of ferric iron was accompanied by a greatest decrease of the culture pH, compared with decrease of pH in the ferric leaching of pyrite; this can be explained by a greater generation of sulfuric acid due to the sulfur oxidation by bacteria (equation 2).
Participation of sulfur or RISC as intermediate in the anaerobic ferric bioleaching of pyrite, was evidenced by the results of an additional experiment of ferric anaerobic bioleaching of pyrite with 1 g/L of Fe(III) iron that showed similar results to those presented above (data not shown).

Noise and vibration reduction is fundamental for
the comfort of the passengers.
Another design milestone is the weight reduction in order to decrease fuel consumption and pollutant emissions.
The analysis of the experimental data allows the comparison of the two different excitation methods.
The experimental data were processed with Polymax modal estimation method, which is based on the Least squares frequency domain (LSFD) method [2].
It was necessary to set the model size to the value of 60 to apply the identification method to the FRFs obtained from the impact hammer excitation, while it was set to 40 to analyse the data deriving from the modal shaker excitation (see Fig. 8 and 9).

Optimizer Input Data.
The data fed into GAMS (the optimizer) (see Table 1) in order to solve the models formulated were obtained from the case study and published literature.
The product per ton input material and emission reduction potentials for various technologies are shown in Table 1.
The ratio of the product to the input material is 1 and there is no emission reduction associated with the technology [10].
Furthermore, GHG reduction of over 9,000 tons CO2eq was achieved which is a laudable effort in GHG emission mitigation.

The motion study identified that proper synchronization of movements by the workers would result in 18% reduction in the total number of movements.
Therefore any reduction in the machining time would result in significant time savings during the fleshing process.
