One plausible explanation is the surface adsorption
of H species leading to the reduction in surface resistance in a fashion similar to the oxide-based
sensors [9].
The experimental data observed indicate that surface adsorption is a possible gas sensing mechanism for the observed gas sensor response of the GaN resistive sensors.
More experimental data are needed to clarify the likely gas sensing mechanisms.

The data have been fitted to the high temperature constitutive creep
equation:
Where σ is the stress, •ε the strain rate, k the Boltzmann constant, T the absolute
temperature, n the stress exponent and Q the activation energy.
Gust et al. [9] pointed out a reduction of the flow stress by a factor of 5 for YTZP doped with BaS, with grain size of 400 nm at 1300ºC.
The preliminary results on the temperature dependence or Q values obtained for YTZP nanocrystals are in good agreements with the few data reported in literature for samples with a mean grain size of 100 nm, but there is a discrepancy with the values obtained for submicron-specimens.

Introduction
Double sides loaded gears are widely used in vehicle, engineering machine and common speed
reduction machines.
The gear bending fatigue property is the basic data to predict bending fatigue life of gear.
(8) The mean stress of middle gear is zero, but the mean stress cycle of gear specimen tested to get the fatigue property is σFmax/2.So mean stress of middle gear should be modified before the gear fatigue property data is used.

Design Of Experiment(DOE)
DOE is a method that how experimental data is obtained and how to deal or analyze experimental data and results scientifically[5-6].
Under the higher holding pressure, the plastic parts can get greater density, shrinkage reduction, improved surface quality and reduce the chance of shrinkage of plastic parts.

Tests for significant difference in water quality between influent and effluent of the wetland were determined by paired t-tests [5] for each set of data.
Reductions of TSS concentrations in constructed wetlands were consistently observed, resulting in removal efficiencies ranging from 84.8% to 86.2%.
Rousseau et al. reported pollutant removal efficiencies of SSF constructed wetlands by examining the influent-effluent data from 12 wetland systems treating domestic wastewater in Flanders, Belgium, averaging 75% for TSS [6].

At least three parallel samples were used in all analytical determinations, and data are presented as the mean of three replicates.
Ratio of urea-to-fish oil higher than 0.80:1 did not cause further increase in the content of DHA and EPA (data not shown).
The results showed a large reduction in ethyl esters of saturated and monounsaturated fatty acids and a remarkable increase in n-3 PUFA ethyl esters.

The test data were collected by IMC data acquisition modules.
As compared to the first-floor isolation without MSD, the compound isolation system achieved significant displacement reductions over almost the entire range of earthquake characteristics considered.

The prediction can lead reduction in computation or experimental time and cost of the practitioners.
However, when the network begins to over fit the data, the error on the training set will typically begin to rise.
The input and response data obtained from numerical model shown in Table 1 is used for prediction purpose.

Processing of Experimental Data.
Using Grubbs rules to get rid of the unexpected data because some improper operations occurred in the experiment [7].
At about 150°C, the flexural strength under boiling water and cold water has a significant reduction.

Result and Discussion
The XRD of La0,7(Sr1-xCax)0,3MnO3 (x = 0; 0.3; 0.5; and 0.7) materials were carried out at room temperature and data were analyzed by Rietveld refinement technique.
