The frequency increases from right to left in the measured data, and the horizontal and vertical axes of the plot represent the real (Z’) and imaginary (Z”) parts of the total impedance of the device.
Scatters are the measured data and lines are the fits with the equivalent circuit given in the inset.
Table 1 summarises the values of the contact resistance (RS), parallel resistance (RP), and parallel capacitance (CP) extracted from the measured impedance data.
It suggest that at the higher dopant concentration, the dopant can affect to the carrier transport properties in Alq3 host material such as phenomenon of hole or electron trapping, resulting in the reduction of carrier mobility in the organic layer[11].
The observation of semicircular behavior in the Cole–Cole plot simply that can be described by an equivalent circuit consisting of a parallel resistor (RP) and capacitor (CP) in series with a series resistor (RS).The dopant concentrations can affect to the carrier transport properties in Alq3 host material such as a phenomenin of carriers trapping, resulting in the reduction of carrier mobility in dye-doped organic material.

After the heating and cooling data from fast and slow cooling area were collected, the filtered data was plotted as is to generate a time-temperature curve or cooling curve.
(a) (b) (c) Fig. 3 Cooling curves (a) WQ, (b) SQ, (c) AQ For the fast cooling area, the data shown in Fig. 3 shows extremely fast cooling of the sample for the WQ case (cooling rate of ~7,14°C/s) in contrast the SQ sample had an average cooling rate of 6,02°C/s.
This is because when the cooling rate is too low, due to the growth of the coarse β-Mg2Si phase, the degree of supersaturation of solid solution is reduced and resulting in the reduction of the mechanical properties after aging [7].
The reduction in the mechanical properties was attributed to the loss of solute atoms which precipitates as coarse precipitates during slow cooling.

These modules were compared with equivalent modules at CIEMAT, which were never exposed to the sunlight, and with nominal data.
The comparison between measurements made after twenty years of operation showed that one of the causes of the maximum power reduction is the change in the slope of the curve near VOC, a behavior that may be associated with an increase in RS.
The comparison with the reference module (ModRef), that is a same type module not exposed to sunlight, and nominal module data (Standard Module, STD) is also presented. 2.3 Infrared, electroluminiscence and SEM characterisation Following are shown (Fig. 2) some examples of the infrared (IR), electroluminescence (EL) and SEM characterization.
Var ModRef and Var ModSTD indicate differences in percentage of the measured values with respect to the reference module and the standard data respectively.
If we consider the effect of dust accumulation, the average reduction in power would extend to the order of 9.84% to 12.92% for dirty modules when compared to reference modules and STD.

After integrating the design parameter modeling with the production one, the program further provides data regarding the production rates and scheduling for the CNC tools.
This module was configured for achievement of the following functions: stocking, realization of complex archives, personalized access, control of elaborated versions, protection of data integrity and restricted access for modifications, control of circuit of technical documentation, classification of components, multi CAD support.
The following specific objectives are proposed for integrating the production activity with the system: identifying the factors and modeling the technological parameters for optimizing the intensive processing (HSC) of complex bladed components with thin walls, made of titanium, steel alloys and aluminum alloys; developing an interface with the CNC processing machines allowing the processing of the modeled solid without any additional data processing.
The project has a big economical impact by creating competence in the production of advanced technologies for critical components in high-technology industries, aerospace industry and turbojet engine construction in particular; creating scientific competence in approaching the design of complex profiles with thin walls (considering the requirements of low jet engine noise, high resistance to dynamic and heat stress, etc.), simulation and testing in a single system integrated with HSC processing and active control; creating the information infrastructure for cooperation with European companies in the industry – providing the guarantee of scientific, technical and organizational competence for complex cooperation in international programs.; a reduction in the time of transfer of the solid models from the design workshop to production, a reduction in the time required to prepare the production, scheduling, planning, launching and follow-up documents, which we expect to increase productivity

Preliminary data reduction and normalization was carried out using the Artemis
software program for EXAFS data reduction.
We have determined the point of inflection to be the point of intersection of two straight lines fitted to data points on the two side of the inflection point (dotted lines in Fig. 3).

Although the each hydride has different characteristic, the processes in electrolysis could be divided into two different parts: Electrolytic oxidation (Eq. 1) and Electrolytic reduction (Eq. 2)
It was found after be injected La in catalyst that cathode not only had better oxygen reduction activities, but La also could reduce solubility of catalytic phase [3].And it was shown that multi-layer catalytic membrane electrode manufactured by alternate deposition had better catalytic activity and stability than these in single- layer membrane electrode [4].
Based on logarithmic change bottom formula, then Eq. (4) could be changed to Eq. (5): (5) Made use of Eq. (5), we took the data charting about cathode hydrogen evolution polarization value and calculation of i0 in these samples respectively,△E was changed from -0.04V to -0.005V, and these results in balance value were shown in Table 2.
Current density, 1.8V vs SCE, in anodic area LSV of different samples could be used to evaluate properties of these membrane electrodes, and the data were shown in Table 2 could be disposed and was shown in Fig 2.
Therefore, via comprehensive comparison about these data, it would be found that D-1 had best hydrogen evolution properties.

For instance, our arable land area was 1826 million mu at the end of 2008, compared to the data of 1951 million mu in 1996, reduced 125 million mu (see table 1).
Table1:Area of the reduction of arable land from 1996 to 2008 Year Area of Arable Land (million mu) Reduce 125 million mu 1996 1951 2008 1826 At the same time,large number of arable land changed to construction land which was expropriated by the government each year(see table 2).According to the data, the area of land requisition from government increased year by year, and more and more cultivated land will be occupied.
Due to the reduction of arable land, the nation’s food security is seriously threatened, what’s worse, if the food security cannot be guaranteed, the social will probably appear some unstable factors, which worrying us most. 3.2 Low efficiency of land utilization The land-use pattern in urban fringes is particular diverse and complex.
Land information management is an important part in land resources management, but traditional approach of land information management is inefficiency, it could not readily show the dynamic changes of land and need too much time to collect data.

As can be seen from the data in this table, in both samples, approximately half of the specific surface area corresponds to micropores and half to mesopores.
It is evident that these are reduction processes which result in the formation of particles with sufficiently high magnetisation values.
According to the X-ray phase analysis, during the synthesis, the FeO, Fe3O4, and Fe phases were formed as a consequence of the reduction of iron oxides by carbon monoxide.
The reduction of iron oxides follows the scheme [24, 25]: Fe2O3 → Fe3O4 → FeO → Fe (1) by the following reactions: 3Fe2O3 + CO = 2Fe3O4 + CO2, Fe3O4 + CO = 3FeO + CO2, (2) FeO + CO = Fe + CO2.
The increase in magnetisation compared to the FeO precursor is due to reduction processes occurring during synthesis, as described by reactions (1) and (2), which lead to the formation of Fe-based particles with higher magnetisation values.
