Therefore, the measured data results in relatively close.
4.2 The relationship between the excess pore water pressure and effective radius
The relationship curves of between excess pore water pressure and the number of calculation step of three different depth position of single direction-perforated pipe-pile with hole is shown in Fig.11.
The degree of reduction for the peak value of excess pore water pressure of measuring points is shown in Tab.4.
It is proved that the pipe-pile with hole would reduce the peak value of excess pore water pressure of the soil which is around the pile in a certain extent, and expedite the excess pore water pressure dissipation. 2) Although the number of hole is different for three pipe-pile with hole type, the corresponding point of excess pore water pressure data are very similar under a variety of conditions.

The alternative cement systems are involving calcium aluminate sulphate (C4A3S) as well as dicalcium silicate (C2S) as major mineral components, which have characteristics of low clinkering temperature and significant green-house gas reduction (HFW Taylor, 1997; Peter C.
Unfortunately, due to lack of performance tracking, there is no enough data available on the performance of reinforced Sulfoaluminate cement concrete after 30 years in use.
At last, we must realize that the results from TGA-DSC analysis are rather comparable with those data obtained from QXRD analysis, i.e. more than 65% aH-C2S and 22% aL-C2S were preserved during cooling process. 4.2 QXRD analysis The quantities of clinker mineral components were analyzed using Quantitative X-ray Diffraction analyzer by Rietveld method (ASTM C 1365, 2011).

.% B4C composites[4].As the sliding distance increases under various loads and sliding speeds the reduction in pin length takes place and the wear rate is low for 0 to 1000 m sliding distance and transition to significant increase in wear rate for higher sliding distance.This significant increase in wear rate changes in the wear mechanism from abrasive wear to adhesive wear [4].Lim et al. (1999) has summarized the governance of particles wear mechanism for composites are mainly reliance on sliding condition.
The addition of reinforcements reduce the wear rate of composites because increases wear from mild to severe by Transition load [9].Basavarajappa et al.(2006) studied the dry sliding wear behavior of metal matrix composites: a statistical approach, in order to collect the data in a controlled way Taguchi design for the experiments is used.
X ray data were estimated by taking ICDD-JCPDS card number (33-225) for B4C and (39-1492) for MoS2, this identifies the B4C and MoS2 phases in prepared composites. 5.3 Effect of specific wear rate on different sliding conditions. 5.3.1Effect of specific wear rate on load, sliding speed and sliding distance for room temperature conditions.

The design resistance of the rib (maximum possible compression force) according to the “A” method is taken as for a conventional centrally compressed column
, (1)
where is the reduction factor for buckling; is the effective cross-sectional area of the rib (stiffener), obtained from [5]; is the partial factor for buckling resistance; is the design value of the yield strength.
The analysis of the table data leads to two main conclusions.
The initial data is specified as the current, , and the desirable, , number of vertical ribs.

MNPs can be specifically designed to increase the current data storage capacity of magnetic hard disks or to be used as biohybrid materials.
Size reduction also reflects in the enhancement of the relative contribution of surface effects.
Neutron diffraction measurements were performed at the HRFD (High Resolution Fourier Diffractometer) instrument at the IBR-2 reactor, Joint Institute for Nuclear Research, Dubna, Russia, which provides the possibility to work in two modes of diffraction data acquisition: high resolution in reciprocal space (using the Fourier chopper and correlation electronics, Δd/d ~ 0.001, where d is interplanar distance) and high luminosity (conventional TOF method, Δd/d ~ 0.01).

Diffuse reflection spectroscope (DRS) data were recorded by an ultraviolet-visible (UV-Vis) spectroscopy (PerkinElmer, Lambda 750).
The DRS data were converted into absorption spectra by the Kubelka-Munk function [15]:
As compared to ZnO QDs, the reduction in the average crystallite size in ZnO:S QDs may be due to the surface scattering of nanoparticles [18].

Introduction
In the transportation sectors such as automotive and aviation lightweight design is a permanent issue, because a reduction in the mass of any vehicle leads to a higher efficiency and lower fuel consumption.
This software-tool automates the entire design procedure, starting from the tessellation of the initially designed surface and ending up with comprehensive CAD data of all single components used for the CNC programming of the manufacturing processes in a CAD/CAM software.
After conducting this automated design and detailing procedure, the component data of the prototype roof is completely elaborated and it consists of 140 individual pyramids, 234 individual triangles and 140 identical connector elements.

Data Analysis: The experimental design was arranged with 20 pumpkin accessions, three pre-drying treatments and two drying methods in split plot with three replications.
The data presented in this study confirmed that the main advantage of pre-drying treatment is shortening the time of drying and then resulting in lower energy requirements for drying [15].
The reduction in pH value of sun dried pumpkin fruit slices may be due to synthesis of organic acid from carbohydrate over the extended period when fruit slices are subjected to sun drying [25]. [30] showed that pH value was highly correlated with TA which is in harmony with the present result reported in this study.
