A simple data transfer strategy based on a finite element type interpolation of the interface degrees of freedom guarantees kinematic consistency and equilibrium of the stresses along the interface.
Considering deformation of the structure in this example is relatively simple and reduction calculation amount, nodes in both sides of contact surface is constrained consistent in the movement.
The data transfer strategy at fluid-solid interface is based on a finite element type interpolation which is sufficient to guarantee kinematic consistency and equilibrium of the stresses.

The experimental data on the o-Ps lifetime in the liquid phase in a broad range of temperatures are in the literature not too rich [7-10].
Experimental data for alkanes fall on a single curve, but for alcohols they are more scattered.
The dependence of l on s∞ was approximated by straight lines fitted to the experimental data – the lines run almost parallel.
If U is of the order 1¸1.5 eV, the shift of l by 0.015 ns-1 corresponds to the reduction of U in alcohol by about 0.3 eV (a very rough estimate).
Data 1(4) (1972), 841-1009

The metal solubilization from
sulfide minerals is a chemical process which requires Fe
3+ reduction.
It was possible to correlate experimental data with a mechanism of bacterial-metal sulfide oxidation, the polysulfide pathway for acid- soluble metal sulfides.
Experimental data obtained in this work support the following conclusions: L. ferrooxidans gets its energy from the oxidation of Fe 2+ and, due to its metabolic necessities, favorably adheres to minerals, according with the indirect contact mechanism.

Abstract.
Reduction in radio-opacity as well as organization of the bone architecture could be observed at the implantation site over time using X-rays (Fig. 3).

Orientation-dependent stored energy developed in 80% cold-rolled
interstitial free (IF) sheet steel was evaluated by reconstructing of data measured using electron
back-scattered diffraction (EBSD) analysis.
The INCA software (Oxford instruments) was used for indexing EBSD patterns and enhancement of unsolved data.
After reconstructing the subgrain structure from EBSD data, the subgrain size and misorientation can be determined.
Subgrain identification angle: 3° Recrystallization Simulation The orientation data measured using EBSD analysis and stored energy data evaluated by Eq. 1 were used as input data for a MC simulation by mapping on square lattice.
A comprehensive comparison of the simulation results with experimental data will be treated in a future work.

In the first part of the paper, the definition of material damping by means of a closed loop in the shear stress - shear strain plane is presented along with a report on literature data associated with damping of coarse-grained soils and the important factors that control material damping of sands and gravels.
Typical free-vibration decay curve of the crushed rock: Data at p'=100 kPa and γ=7.5×10-3% during steady-state vibration In Fig. 3, plots of normalized stiffness degradation (G/Gmax) and material damping increase (Ds) are given as a function of shear strain amplitude (γ) at two different levels of p' equal to 50 and 100 kPa.
Because of the limited number of data points reported in the study, it is hard to make firm conclusions regarding the differences in the obtained damping values using the SSV and FVD methods.

Tests using the new compensation grinding method demonstrate the reduction in
the form error of aspherical parts.
Based on the measured data, the center of the grinding wheel C is compensated in the radial direction of the grinding wheel and moved to point C'.
By adding up the data of Fig. 6 and Fig. 8, the actual distribution of the grinding wheel radius is calculated as shown in Fig. 9.

Through combining the test data and computing results, two recommendations used to quantitatively determine the ultimate failure load of spherical joint in test are proposed.
In results, the test data may vary among different testers even under the same condition.
DH3185 data collecting system was used for data collection.
Partial data are shown in Table 3 and Fig.4.
The accuracy has been confirmed by the test data; 3) The diameter of tube, the thickness of the sphere wall and the diameter of sphere have influence on the bearing capacity of WHSJ.

Based on experimental data some equations are adjusted and the results obtained are discussed.
The amount of data obtained revealed to be sufficient to adjust a numerical model.
Adjust to the Residual Soil Experimental Data In order to obtain a numerical result for the laboratory results, the equations presented in the previous sections were tested and evaluated.
Figure 3(a) presents the adjust to the data resulting from the filter paper method while Figure 3(b) represents the adjust to the data resulting from the pressure plates.
Models with higher number of fitting parameters tend to adjust better the experimental data, although introducing additional numerical complexity.
