Growth at higher Rg (~5µm/hr) with HCl addition
caused an additional order of magnitude reduction of
the BPD concentration (4.4x10
3 cm-2) (Fig. 1b), thus
indicating that higher Rg as well as possibly different
effective Si/C ratio caused by HCl-induced
dissociation of the Si gas-phase clusters enhanced
BPD conversion during the growth.
ThD arrays (substrate-related) Dislocation-free at mesa-walls downstream step-flow BPD generation at mesa-walls upstream step-flow Rare BPD at mesa-walls with a small angle to step-flow 10 µm [ ]0211 Summary The previous photoluminescence and optical microscopy data indicating good quality of the halocarbon epitaxial growth at temperatures as low as 13000C [1] were supported by analysis of the dislocation concentration.

From the data obtained, it was found that the acid value of SHL noticeably decreased after heating.
However, the reduction of acid value was not explicitly observed in SHL-PHT that reacted for 6 h and 24 h (SHL-PHT6h and SHL-PHT24h).

The small ratio difference between the design and experimental data is linked with the technology process’s uniformity (dimensions, channel length and ohmic contacts).
This slight change is due to the reduction of the channel resistance and increases of the drift resistance contribution to the VDMOS conduction mode.

Compared to steel and concrete, bamboo has fairly good mechanical properties, thermal insulation performance, good effect of energy conservation and emissions reduction[2].
Shear experiment results show that when the shear span ratio less than or equal to 2, composite shear damage occur, when the shear span ratio is equal to 3, damage characteristics and damage of the bending are similar, and put forward a kind of composite beam shear bearing capacity calculation method, calculated value agreed well with experimental data

As well as their uses as permanent magnets, common applications are as magnetic recording and data storage materials, and as components in electrical devices, particularly those operating at microwave/GHz frequencies [1].
The decrease of Ms after substituting more La content from x=0.20-0.40 may be due to magnetic dilution with a change of the Fe3+ (3d5 high spin) valence state to Fe2+ (3d6 low spin) state on a site by substitution of the Ba2+ sites with La3+ ions and the existence of spin canting promoting reduction of superexchange fields [4].

Anatomical reduction and internal fixation of diaphyseal forearm fractures using conventional stabilization systems or locking compression plates (LCP) still remains the most used fixation methods [2, 3].
These charts show the absolute value of the standardized effects based on the t-test by comparing the mean square of the simulation data against the estimated experimental error.

Analysis of the lighting conditions on the example of a selected room
The basic analysis of the lighting conditions was conducted for a chosen room of a building, located in Warsaw, with the assumption of different parameters for light permeability through the transparent partitions, variable depth of a room, different orientation towards four cardinal points, different seasons and other data required for calculations.
Current construction regulations impose new requirements on transparent partitions aiming at the reduction of heat consumption and indirectly of electricity consumption in the buildings. 2.

Reduction in the thickness of the acetabular liner could possibly affect the load bearing capacity, wear behaviour and contact stresses of the AHJ.
The wear data was taken for every 10 thousand cycles.

To InSAR LF estimate serves as directly estimate the neighbor pixels difference in elevation.If using 2-D sine-wave model represents the LFE, then:.And LS phase unwrapping based on LF estimate:

where,are frequency of pixelbefore and after phase unwrapping, respectively.The resulting LS unwrapping is exact up to a high noise level (white Gaussian noise=0.8 on the previous synthetic fringes).If using the LF estimate, without any filtering, a strong reduction of the noise phase variations visible on figures Fig.1b and Fig.1d.
