In some cases, with significant reductions in the load-carrying capacity of the structure, external reinforcement methods are required.
A review of effective tests and methods for evaluating the self-reduction of materials based on cement is given in [1, 2].
Results Table 1 presents data on urease activity of Bacillus pasteurii based supplements for various astringents. pH0 is the initial value of the acidity of the medium, pH1 is the final value of the acidity of the medium.
Analyzing the obtained data on the optimal cell concentration in percent of the mass to the binder, we can conclude that the most effective is the concentration not exceeding 0.015% of the cement mass.

However, the degradation in the fatigue safety factor (FSF), a 10% reduction compared to the standard case, was the most significant of the key clinical attributes investigated.
Its fatigue safety factor declined even further from the standard case of 3.05 to 1.68 with a staggering 45% reduction, almost trimmed by half from its original value.
Calculated data of the standard case were well below the Goodman diagram failure line, indicating that the studied balloon-expandable stent (standard case) is able to pass the fatigue life of 4 x 108 cycles under pulsatile fatigue loading.
Comparing Figure 5(a) to Figure 5(b), wherein the very same stent but with through-hole reservoirs on the entire stent was assessed, shows that the calculated data of this specific depot stent migrated towards the Goodman diagram failure line, indicating a significant drop of 34% in fatigue safety factor and thus much lower fatigue resistance to systolic/diastolic blood pressure.

Source data: Copper tube, d = 16 mm, l = 100 mm, internal surface roughness Ra isn't more rougher than 0,63 µm.
Collected data of main operating FEPP conditions influencing on internal surface quality measured by roughness parameter Ra.
The roughness decreases in the range from 0,24 µm to 0,06 µm at reduction of the EC dimensions (DEC) proportion to diameter of tubular work piece (dtube) form 4/8 to 2/8 and electrolyte temperature from 90 °C to 70 °C (Fig. 3.).
The roughness parameter decreases in the range from 0,21 µm to 0,06 µm at reduction of electrolyte concentration from 7% to 3% and the flow speed from 0,2 l/sec to 0,1 l/sec.

These alloys consist of the addition of β-stabilizers in order to stabilize the β microstructure in the alloy, providing reduction of Young's modulus, increase in hardness and corrosion resistance [11,12].
The phases were identified through comparison with simulated diffractograms using the program Powdercell [17], inserting data of the , and Ti phases as space groups, lattice parameters and atomic positions [18].
This indicates a 42% reduction in the Young's modulus of the alloy described in the present work.

Analysis of the oxygen and nitrogen content in the steel samples was performed on a TC-600installing company «Leco» smelting reduction method (graphite crucible) in a pulsed resistance furnace in an inert gas (helium).

To obtain more complete data on the effect of modifying the complex mixtures with subsequent heat treatment needs further research and testing.

The proportion of carbon dioxide emission of the developed nations would ascend if including the data from the industrial revolution to 1990, because the developed countries has produced 95% of carbon dioxide then, while, those developed countries still own the proportion of 77% during 1950 and 2000 when some developing countries accomplish industrialization.
IPCC[2], and UNDP[3] set out the responsibility of countries of different development levels in the realization of global emissions-reduction goals.
From the analysis of completed total carbon emissions reduction of some European countries, Mi Hong and Zhou Wei[7] believed that because of different industrialization periods, China’s carbon emissions will reach the peak with the completion of urbanization and industrialization and the exact peak time would be calculated out.
With the overall consideration of economic development and the restriction of resources and environment, Du Limnin[9] analyzed China’s provincial carbon emissions with the application of panel data.

Further annealing at temperatures of 600°C, 800°C and 1000°C produced no significant reduction in the intensity of the O 1s peak.
These XPS results consolidate the ellipsometry / MEIS data, suggesting a Si-O-C interfacial layer that cannot be easily removed by HF treatment or by annealing.
Furthermore, the reduction in intensity of the oxygen peak in the sample with no POA (Figure 2a and 2b), suggests that the Si-O-C interfacial layer may originate from the post oxidation annealing (POA) process.
Indeed, preliminary data of interface state densities for this sample, extracted from quasi-static C-V measurements are some of the lowest reported [9], (over an order of magnitude lower than for conventionally oxidized samples).

In an iso-volume context, these chromium alloys offer a 10-15% mass reduction as compared with IN100 (one of the lightest blade superalloy) or about 25% mass reduction as compared with third- or fourth-generation single-crystal superalloy (with a typical density of 9 g.cm-3).

For longer times, a significant amount of bainite plates have grown into the austenite grains leading to a reduction in the austenite fraction with time.
These data indicate that only small grains with a high carbon content remain untransformed at 100 K.
The green dots correspond to the data obtained by in-situ X-ray diffraction (taken from ref. [7]).
A decrease in the aluminum content causes a reduction in the austenite fraction and the maximum occurs at shorter holding times. 2.

XRD data were collected at room temperature using a Rigaku D/MAX-B diffractometer and Cu Kα radiation.
The refinement of the XRD data based on the R3c space group was successful with correct description of all the observed intensities.
As LMT content increases, a gradual reduction in dielectric constant is observed.
As LMT content increases, a gradual reduction in dielectric permittivity of (1-x)NBT-xLMT ceramics is observed.
