In fact, the gap between model and experimental data shrinks significantly at low stresses, if one looks at the creep rate at the point where the density ρf of free dislocations is first established while the subgrains have not yet formed.
Experimental data show that this point is reached rather early in a creep test, during primary creep [2].
Thus the simple model of steady state deformation, based on the steady state of free dislocations, is in fact in reasonable agreement with the experimental data for Al at low stresses in Fig. 1.
When the glide of free dislocations is suppressed by stress reductions of sufficient magnitude, boundary migration continues as an autonomous process and becomes responsible for nearly all of the strain [25].

Data were subjected to a one-way ANOVA using the SAS™ software (SAS Institute Inc 1989) to test for the main effect of breed and for the effects of low temperature within each level of temperature.
The analysis of shoots dry weights was similar to that for the fresh weight (data not shown).
These data reflected that in breed No. 1 the content of unsaturated fatty acids increased, while the content of saturated fatty acids decreased under low temperature stress, in breed No. 2, reverse trend was observed.
The growth inhibition by low temperature possibly caused by reduction of photosynthesis and transpiration [17].

Shaped holes provide a promising solution for film cooling, except structural force reduction concerns and spatial restrictions in the blade interfere with applications in some conditions.
Also, in order to identify the validity of the findings, a comparison between the data attained from this investigation with classical cylindrical for gas turbine blades data sinha et al [22].
It should be mentioned here that the modified hole film cooling is almost a new concept; therefore, to the best of the authors knowledge, there is no available experimental data in the open literature The values of film cooling jet significantly and thereby reduce theeffectiveness of film cooling.

The graph is based on NMR spectroscopy data.
Reduction of the thiocarbonylthio end groups to yield thiol groups can be easily achieved using a primary amine [26-29] (Figure 1).
The disappearance of the pink colouration, the dithioester group’s absorption at 310 nm in the UV spectrum, and of the aromatic proton signals of the dithioester groups in the 1H NMR spectrum (data not shown) confirmed the complete cleavage of the dithioester functional group.
The graph is based on GPC data.

Reduction of the System Inductance The EMC dynamic properties can be improved by reducing inductance.
Losses were set for the active elements of the model according to the data in Table 2.
The geometry, winding data, the dimensions of the sleeve between the armature and the magnet, as well as the working air clearance should be optimized.
All possible measures should be used to obtain benefits and advantages: optimizing dimensions and winding data, using high-performance materials, the elimination of saturated sections of the magnetic core, choosing the optimal temperature conditions, and arranging an effective heat removal system.

During the seamless tube production, the quality control section of the factory recorded the energy data.
The tube elongation and cross-section reduction starts after contacting the plug and helps to forward-moving the billet.
The collected simulation data made it clear that the total power with increasing friction coefficient grows (Fig. 5c).

As an efficient treatment method for MSW, composting is widely used in China because of its waste reduction, minimum pollution and maximum reuse [1].
Data in Table 1 showed that, the A200~226values increased from 0.927 to 6.127 during composting, indicated that the content of inorganic nitrogen increased, especially nitrate and nitrite included.
Data in Table 1 showed, SUVA280 increased from 0.008 to 0.036 with the increasing compost time, indicated that the molecular weight of the organic matter increased.
Data in Table 1 showed that the S275~295 value was significantly positive with the DOC content.

This assumption contradicts known data on spectra of the carbon austenite and, specifically, the manganese-free austenite whose spectrum includes the Fe-Fe-C doublet sub-spectrum with splitting of about 0.62 mm/s [14].
Considering the absence of Mössbauer studies into the superfine magnetic structure of the Hadfield steel and the ambiguous interpretation of data on cold-work hardening, we posed ourselves the task to analyze Mössbauer spectra of the steel at temperature above and below TN, down to room temperature.
Treatment 3 included plastic deformation by rolling (30-% reduction).
Consequently, taking the adequate experimental data, they proposed [11] an inconsistent interpretation, which assumed the deformation redistribution of carbon from manganese to iron neighbors.

Introduction Today’s increased demand for high data, low profile, low loss, and wideband antennas gives meticulous advantages to microstrip patch antennas [1] by having proper design and use of impedance matching techniques.
Further, to improve various qualities of circuits like diversity parameters, channel loss, gain, data rate, and reliability of the system, MIMO systems are relied upon [3].
The PIN diodes are designed in CST Studio Suite using RLC lumped elements by utilizing the data sheet of PIN diode as shown in Figure 5.
