In patients with ventricular arrhythmias we identified zones of asynchronous contraction of the myocardium (ACM) and reduction hemodynamics with increasing intraventricular dyssynchrony.
Data are shown as arithmetic average ± standard deviation (M ± SD).
The data do not obey the normal distribution (by the Kolmogorov-Smirnov test), that is why the accuracy of the inter-group differences were evaluated in accordance with the nonparametric tests and Wilcoxon Mann-Whitney, the relationship - by Pirson.
These data indicate that the right ventricular dyssynchrony affects its contractile function.
Performing RFA procedure resulted in a significant reduction in intraventricular dyssynchrony of the right ventricle and reduction of interventricular dyssynchrony.

The data have provided useful insights into the 3D geometric complexity and its control over the mechanical and hydrological properties[1].
In contrast, there is a paucity of mechanical and microstructural laboratory data on porous limestone.
Micro CT data on intact samples μCT data were acquired on cylindrical samples (4 mm diameter) of intact Indiana limestone at the High Resolution CT facility at University of Texas at Austin, with a relatively refined resolution of 4 μm (Fig. 1).
Microstructural analysis and CT data on deformed samples The μCT data on a sample of Indiana limestone deformed hydrostatically up to 175 MPa of confining pressure highlight macropore collapse as the dominant mechanism for the inelastic compaction (Fig. 7a).
We would like to thank the laboratory 3S-R in Grenoble where part of the CT data was acquired.

Applying the method of finite element to research the composite damping vibration reduction effect of circular saw blade.
Extract three circular saw blades to finite element simulation analysis as relevant data plotted as shown in Figure 1 and Figure 2.
Contrast Figure 6 and Figure 7, cost the same time the C saws outer axial vibration speed is less than B outer axial vibration speed, it also explain the effect of damping vibration reduction.

On the contrary, rolling is the most probable technique to be scaled for fabricating large bulk sheet or plate samples, however there are very limited data on superplasticity of rolled Mg alloy [24].
Afterwards, the TRC sheets were heated up to 400 °C, kept at this temperature for 2 h, then rolled by multiple passes (with about 10% of thickness reduction per pass) with re-heating between them, according to the data in Table 2.
The sheets were reduced down to 2.7 mm, which corresponds to a total thickness reduction of about 60%.
The reduction in the grain size, characterized by an average value of about 7 m, is evident.
The larger grain size measured in the specimens tested at the lower strain rate of 5·10-4 s-1 is clearly related to the longer exposure time at the testing temperature, as shown by the data in Table 3 [30].

The deformation of the first billet in the des with elastic elements according o the following scheme: [reduction (cross shear) - a turn around its axis by 180 0 - straitening - a turn around its axis by 90 0 - reduction (longitudinal shear) - a turn around its axis by 180 0 - straitening] - the first cycle. 2.
The deformation of the fourth, fifth and sixth billets is made in the flat dies with reduction and according to the deformation schemes corresponding to the deformation in the dies with elastic elements.
The third billet was deformed in the dies with elastic elements with 35% relative reduction which allows to obtain the billet sizes 130x251x368 mm, forging reduction being 1.19, 1.27 and 1.54 accordingly.
The data obtained whet studying U-8 steel microstructure are given in table 1.

Introduction The diffusivity of vacancies (V) and of self-interstitials (I) in silicon is known from electron irradiation data [1-3] to be remarkably high even at cryogenic temperatures.
The data on the size and density of grown-in voids [4, 5] allow to deduce the vacancy diffusivity at the void nucleation temperature Tn (typically around 1100oC); the deduced value, » 3x10-5 cm2/s, is close to the value of 2.7x10-5 cm2/s resulting from Eq.(1).
There are however some other data which indicate a very low diffusivity of V.
The vertical bar shows a range of apparent vacancy diffusivity deduced from RTA data.
The corresponding profiles (solid curves in Fig.2) provide a good fit to the data.

Polarization data revealed that these surfactants act as mixed type inhibitors.
Confirmation of these various independent techniques proved validity of the obtained data. 1.
Gamry applications contain DC105 software for DC corrosion measurements, EIS 300 Software for electrochemical impedance spectroscopy and EFM140 software for electrochemical frequency modulation measurements a long with a computer for collecting data Echem analyst 6.03 software was utilized for plotting, graphing and fitting data. [7] 2.5.1.Potentiodynamic Polarization The electrode potential scanning from (-1000 to 0.0 mV vs SCE) was done spontaneously to get Tafel polarization graphs at open circuit potential at scan rate of 1mVS-1.
So the definition of Ecorr is the potential at which the rate of oxidation is exactly equal to the rate of reduction.
The electrical circuit model used to fit experimental EIS data which obtained from carbon steel electrode in 1M HCl.

According to literary data, the treatment of such fractures is not effective enough, which leads to a prolongation of rehabilitation periods and disability, especially among patients of older age groups.
Data analysis was carried out only on officially published sources.
Available data on three- and four-fragment fractures indicate the possibility of a violation of vascularization of the humeral head, dislocation and cartilage damage with subsequent necrosis of the head and collapse, which is observed in 30-100% of cases.
Also, there is not enough reliable data on the treatment of ipsilateral fractures of the humerus, at the level of the proximal and diaphysis.
Open reduction and internal fixation of proximal humeral fractures with use of the locking proximal humerus plate.

Production data and by-product data were collected in the integrated steelworks.
Transportation data were calculated by the modes of transportation and transportation distance.
Upstream data were obtained from Gabi 4 software [14].
Steelworks always have statistical data for mean values, so the coefficient of variability (the quotient of mean and standard deviation) should be determined first.
The coefficient of variability is defined by the data quality.

Details of an experiment conducted to find compression characteristics of bleeder of varying thickness and the number of layers and related data that was used in the FE analysis are discussed in this paper.
Applied compressive load versus reduction in thickness were measured and recorded.
From the data, change in porosity (φ) and void ratio (e) can be obtained as: φ=φ0Instataneous volume of bleederInitial Volume of bleeder ; e=φ1-φ (1) Fig. 2.
Because of the availability of the data, Graphite/Epoxy prepreg system was used for the simulation.
The reduction in resin content with 4 mm bleeder is 3% whereas for 8 mm bleeder it is 5%.
