In the post-earthquake survey, large amount of data on seismic damage and functional status of water supply systems was obtained.
Based on these valuable data, the seismic damage feature of the water supply network of 15 cities and counties and the performance failure status of water supply network in 26 cities and counties was discussed; the seismic damage phenomena, damage proportion, damage feature and damage degree of several kinds of water supply pipeline under different earthquake intensities are analyzed.
Damage Analysis Of Pipeline Damage comparison among pipes of different materials Based on the basic data and seismic damage data, the current state of the pipeline in 13 investigated areas with the site classification of II is showed in Fig.1, and the seismic damage ratio of different kinds of pipes in the Whenchuan earthquake is listed in table 1[1].
Conclusions The seismic damage phenomena, damage cause and degree of several kinds of water supply pipelines (especially the newly constructed PE pipe) under different earthquake intensities are compared and analyzed based on the post earthquake survey data of water supply system in Wenchuan Earthquake.
The seismic performance of the water supply pipeline is further understood and the following conclusions can be made: a) As the damage of buried water supply pipes is the main cause of the reduction or loss of water supply system’s function, new types of pipes with good seismic performance (e.g.

The data obtained during these flights indicate that temperature differences of up to 30˚C develop between the fuel at the base of the tank and TAT.
These expressions were used to determine theoretical module performance for comparison with experimental data
Theoretical model of power output using real flight data.
Finally the rig was connected to a Delta-T DL2E data logger for measuring and logging temperatures, voltage outputs and resistances.

Therefore it was replaced by a tipping bucket and data logger which allowed higher accuracy [10].
Analysis of the Climate Data Set The climatic data set comes from meteorological station Bratislava – Airport (altitude 133 m above sea level, longitude 17.21°, latitude 48.17°).
Authors would like to thank to the SHMU for providing the measured climate data.

A similar reason was reported elsewhere to explain the density data with this behavior [12-14].
It will be seen later that this change is well correlated with the porosity data of the ACMs electrodes.
However, the data for the ACM06 exhibit a significantly higher adsorption capacity.
These data seem to suggest that 6 wt.% of graphene is an optimum amount to be added into the GMs.

Though high heels increase women’s height and enhance femininity [11], many scientific data have proved that regular high-heeled shoes adversely affect human health [4].
For data acquisition, ten sets of data in walking test were collected for each type of shoe wore by each participant.
Data collection and statistical analysis The kinematics data collected from participants wearing either HHS or FBS walking tests were normalized to get an averaged ankle joint angle profile, knee joint angle profile, and hip joint angle profile in one gait cycle.
The kinematics and kinetics data of the two kinds of shoes were analyzed by a paired sample T-test (p < 0.05).
Discussion The purpose of the study was to analyze the biomechanical parameters, kinematic data (joint angle and ROM of ankle, knee, and hip joints), kinetic data (GRF) and plantar pressure (PP, FTI, MF, and CA) of shoed with HHS and FBS, to study the impact of HHS on the biomechanical characteristics of lower limbs of young females.

It is observed that, there is a reduction of tensile strength and decrease in hardness of the steels prepared with addition of either/both the alloying elements; however there is an increase in ductility, which is helpful for cold rolling operation.
Circular cross-section samples with gauge length 20mm and diameter 4mm were prepared and each data point is average of tests of 4 samples.
From the data it is found that the UTS of plain SS316LN is highest.

The results that are reported in this paper show a good agreement between complex impedance spectroscopy data, scanning electron microphotographies of the glass/metal interface and previous results obtained using stationary electrochemical techniques.
In these conditions, the degradation of the alloys that are immersed in the molten glass is generally governed by oxido-reduction reactions [1-11].
The solvent electroactivity domain extends approximately from -1.2 to +0.1 V [2,4] It is limited in the negative potentials by the reduction of the silicate network in accordance with Eq. 1: − −− +→+ 2 0 4 4 O4Sie4SiO (Eq. 1) The oxidation anodic limit of the solvent corresponds to the oxygen gas formation, due to the oxidation of the O 2 ions (O 2 � ½ O2 (g) + 2 e -), and to the silicate network according to Eq. 2: − − − ++→ e2OSiO SiO 22 12 3 4 4 (Eq. 2) The main formal potentials of the redox couples encountered in silicate melts are reported in Fig. 2, [4, 15-17].The potential scale is useful to assign the anodic and cathodic reactions of a corroding alloy.
The results of previous studies are in good agreement with the data collected by EIS.
