Current Test Protocols The current accepted standards for determining resilient modulus are: § Determining the Resilient Modulus of Soils and Aggregate Materials (AASHTO T 307-99) § Harmonized Test Methods for Laboratory Determination of Resilient Modulus for Flexible Pavement Design (NCHRP 1-28A) There are various differences and similarities between the two standards related to deformation and load cell location, stress sequences(number, load duration, magnitudes), load pulse form and compaction methods.
Required number of blows per lift (n) can be calculated using Eq. 1 recommended in NCHRP 1-28A: n=CE*VN*W*h (1) whereV, W, and h are the volume of the specimen, weight of drop hammer (10 lbf), and drop height (1.5 ft) respectively.

Because increase of porosity and size of pores in the bonding layer causes that the glass liquid penetrates into the bonding coating and part of glass liquid adheres to MoSi2 grains[15].
With increase of PMMA content, the number of thermal shock cycles gradually increases.
The MoSi2-BAS-P5 (Fig. 6 (b) and (g)) and MoSi2-BAS-P10 (Fig. 6 (c) and (h)) coatings still cohere with porous matrix when the number of thermal shock cycles reaches 95 times.

Preliminary Results and Discussion There are number of horizontal well flow models in the market.
Butler’s rate equation for steam assisted gravity drainage is not addressing the number of issues like the anisotropic conditions, well locations, well parameters, rheology of heavy oil with steam, relative permeability of oil and grain compaction due to high temperature and high drawdown. 3.

At a much larger magnification, a dense and equiaxed grain morphology was revealed (Fig. 3b), which is a typical feature of the slow growing α-Al2O3 scale [19-20].
For steel A, the original grinding marks were no longer observable on the surface at 3000 h oxidation (Fig. 3c), which, instead, covered by a loosely packed oxide scale with large numbers of micropores (Fig. 3c and d), signifying that the scale formed was rather thick.
And also, beneath the oxide scale, a large diffusion zone formed with a thickness of approximately 85 μm in which large numbers of needle shaped precipitates were present as shown by the enlarged image in Fig. 4c.

Row number one is for the development of the control sample.
The Rockwell hardness number of the samples was then evaluated using ASTM E18 standards.

So far a number of reports are mainly about the nickel plating on AZ series magnesium alloy and little information has been reported on ME20M magnesium alloy[3，13，14].
It can be attributed to the rare earth element in the ME20M magnesium alloys, which decreases the size of grains and increases the strength of magnesium alloys.
The diameter of bigger nodular structure was 10 mm, which is composed of a number of smaller granules.

Although researchers to bubbling fluidized bed flow characteristics inside the large number of experiments and numerical simulation, but because the gas solid two phase flow of complexity, the flow characteristics inside the fluidized bed research remains to be in the further.
Gas distributor is a plate with a certain number of holes.
In the static bed height is 300mm, due to bubbles not closed, the bubbles left no grain, there is no analysis on the left of bubble particle.

This phenomenon is also reflected in the observed microstructure: a more robust Si-network and a greater number of observable precipitates within the network
The observed microstructure features a finer silicon network with a smaller number of precipitates within individual grains with minor failures in the Si-network, where it is not completely compact, as compared to the as-built or T170 state.

Meanwhile photogenerated electrons and holes respectively from conduction band and valence band can also be captured by impurity energy levels and separating the electrons and holes, which lead to a decreasing of rate of their recombination, increase the lifetime of carriers and increase the number of carriers in per unit time and per unit volume.
This may be due to that when the doping amount is less than the optimum amount, with the increase of dopant concentration, the number of the doped ion trap provides increased, enhance the inhibition ability of electron/hole recombination and the photocatalytic performance improves.
The samples of 0.2% Ce and 0.5% Fe doped TiO2 sintered at 500oC for 2 h, XRD patterns show that the crystal is anatase and SEM pictures show the morphology is small grain of porous spherical structure.

Despite the large number of works devoted to the study of the properties and machining technologies of alloys Al-Mg system [3-13], obtaining longish deformed semi-finished products from these alloys is an urgent task for production.
The following data chosen as the initial data and boundary conditions for modeling: the material of the workpiece is an aluminum alloy, the material of the instrument is tool steel; billet material isotropic; the conditions of contact interaction between the workpiece and the rolls were accepted according to the Siebel law with the friction index at the metal deformation in the rolls ψr = 0.9 and on the die ψd = 0.3; friction on the contact of the rolls and the die were not taken into account; relative reduction during rolling 50 %; the initial temperature of the workpiece Tb = 400-550°C, heat exchange with the environment and the tool; the initial temperature of the die (Td) and of the rolls (Tr) varied from 100 to 200°C, and heat exchange with the environment and the workpiece takes place; the number of finite elements into which the workpiece is divided was 32 thousand pieces.
