However, this approach results it difficult separation of catalyst and the reduction product.
There are two reasons to explain these data.
Secondly, annealing can remove some functional groups, but it is not a complete reduction.

Fig. 2 shows reduction currents obtained from Sb-SPCE and Bi-SPCE electrodes.
It was found that increasing pH value caused a decrease in the reduction peak.
However, the reduction peak current was highest at pH 4.0 as shown in Fig. 5.
Briefly, 100 mg.L-1 MT in BR (pH 4.0) containing 12 mg.L-1 of Sb as a catalyst with a selected deposition potential of 1 V (data not shown) was carried out to examine the effect of deposition time on Sb-SPCE.
However, increasing deposition time over 90 s caused a decrease in the reduction peak current.

The accumulative stress curve of the bridge panel in the section of tension position From the table 1 we can see the measured data only a few have deviation (data with * in the table) with the calculated data, the most data is a little smaller than the computational data; the main reason is that the finite element is ideal model.
Compared the displacement data the deviation is very small.
From the fig.11 we can see the tested data is good in agreement with the calculated data in the N1 and N2 tension process.
Compared the displacement data the stress data is in good agreement.

The use of UVGI lights with HEPA filter resulted in significant reduction in the concentration of microbes and respirable particulates within the ventilation systems.
1.
Air sampler pump was used to collect RSP samples over a 5-min period for each occasion to obtain a representative data.
The number of microorganisms expressed as CFU/ m3 was estimated according to equation 1[18]: (1) where: a - the number of colonies on the Petri plate p - the surface of the Petri plate t - the time of Petri plate exposure All the collected data were then entered into a spreadsheet i.e.
Where normality and homogeneity of variance of the data were confirmed, single classification analysis of variance (ANOVA) F test was performed.
Post installation of UV-HEPA unit showed a drastic reduction in the concentration of fungi colonies in both laboratories with CL values reduced to 0-194CFU/m3 while NRL values dropped to 0-278CFU/m3.

Simulated results show that RBF can be very successively used for reduction of the effort and time required to predict the stress-displacement response of suspension arm as FE methods usually deal with only a single problem for each run.
RBF networks were independently proposed by many researchers [4]-[5] and RBFNN are also good at modeling linear data and can be trained in one stage also learn the given application quickly.
To properly train the network, the necessary suitable independent training, testing and valid data sets in shape of maps are collected, synthesized and applied to the network.
For effective predicting of suspension arm, the simulation data from finite element analysis has been used for training and testing.
The results show that RBFNN can be very successively used for the enhanced navigational performance and error reduction.

The reduction of manganese and CODMn met the China Drinking Water Regulations.
Coagulation and ozone pretreatment aimed at the reduction of negative effect of membrane fouling.
The results of total iron and manganese of the permeate water shown in Fig.3.As can be seen from data presented in iron of permeate water was below 0.3mg/l, which met Chinese drinking water regulations.
A 36% reduction in DOC was obtained in the experiment, and 49% of UV254 was removed.

In other words, the value a =0 offers the narrowest bandwidth, but the slowest data rate.
Binary data is first separated into even and odd data stream Data Q and Data I.
Then, the data are fed to MOS switches that select quadrature sinusoidal waves Sin Q and Sin I.
The line length is 1m and the data rate is set to Fig. 6.
In this paper, we investigated how to improve the data rate of signals and to reduce crosstalk noise.

Literature [6] introduced an assistant cluster head to transit data (ASCH).
The energy consumption is described as Equation (1): (1) Where it sends 1-bit data from node i to j, l is the length of data, is the energy consumption of 1 bit, and is the needed energy of power amplifying.
The second phase gathers data and processes data.
a) The Agent mental factor Definition1: confidence is defined as the ability of node to transform data and become the head node.
Figure 5 show that EACA achieves at most 16% reduction in energy compared with LEACH and 14% reduction in energy compared with ASCH.

In this paper, author have carried on many tests about PI film’ DC breakdown and flashover performance in room temperature and liquid nitrogen temperature, and get some useful test data.
From the table 1 and figure 1, we conclude that the data dispersity of PI film’ breakdown strength was lesser, it testified the insulated performance of PI film was stable.
The data dispersity of PI film’ breakdown strength showed increased trend with the temperature reduction, and PI film’ breakdown strength enhanced obviously, the breakdown strength of PI film which thickness is 0.025mm at 78K enhanced about 23.9% than at 300K.
After the third flashover, the value of flashover tended to stable value, and the data dispersity was very well.
Its breakdown strength in room temperature enhanced by a large margin than in the liquid nitrogen temperature, and the data dispersity of breakdown strength increased obviously in room temperature. 2.
