See table 1 about the tested data.
The content of air entraining agent can reach the air content (≤20%) and also have fine keeping property, i.e. the air content reduction after one hour’s standing can not be more than 4%; at the same time, the compressive strength must reach more than 75% of the reference building mortar.
The mixing of air entraining agent helps reduce the water consumption of building mortar; the increase of air entraining agent means the increase of water reduction. 1.1.3 Relations between the air entraining agent content and compressive strength of mortar As the in crease of air entraining agent content, the compressive strength of mortar goes down. when the air entraining agent content is more than 7.98/100,000, the compressive strength ratio of mortar will be less than 75%.
From the above analysis we can find that the air entraining agent’s influence on mortar performance is: as the increase of air entraining agent, the mortar’s air content will increase and the water consumption will reduce and at the same time the bleeding water will reduce too; while as the reduction of the mortar density, the compressive strength will reduce too. 1.2 Thickening agent’s influence on building mortar performance Another important element in mortar plasticizer is the thickening agent methyl cellulose ester.

The following process parameters were selected based on results of the previous research [11]: an extrusion rate of 0.1 mm/s, an oscillation die frequency of 1.5 Hz and a total reduction degree of 16 (calculated as a ratio of cross section area of the rod before and after the extrusion).
The total thickness reduction of 90 % was achieved in two consecutive rolling passes.
The cold rolling to 90 % of the thickness reduction with an equal speed of both rolls (R=1, ESR) of the KoBo extruded bars leads to a formation of commonly observed in deformed metals microstructural features such as deformation bands.
These results supported by a proper literature data allows concluding that the grain refinement in both the KoBo extrusion and the DSR method is affected by a strain mode and temperature induced activation of a dynamical structure transformation.

So Gauss filter make the characteristic of image blurred during noise reduction.
Preserving the important information such as target edge during noise reduction has been the goal in this domain.
This can reduce diffusion of Gauss filter near the target edge and preserve the edge better during noises reduction.
In the literature [3], a function has been proposed to measure the oscillations in the noisy data and is given below:

A significant reduction in landfilling of ELTs is expected as well, without losing the properties of the traditional concrete.
According to [7], the class of consistency for each average slump values (mean value of two data) was identified.
Referring to Fig. 1a (single layer panel), the steel bar reinforcement was reduced from f5/20 cm to f6/40 cm in the case of RSFC with an overall reduction of 28% per square meter.
In the case of insulated double layer panel, only the non-structural layer was realized with RSFC and the reinforcement of this layer was reduced from f5/20 cm + longitudinal f8/40 cm to f6/40 cm, with an overall reduction of 55%.

This type of undertaking enables businesses to obtain tangible economic benefits from the reduction of expenses on materials, waste disposal, and also non-tangible environmental benefits.
Monitoring of fluids is supported by a purpose-build expert computer system in which data are collected on the characteristics of the monitored products and the expertise relating to their functional usefulness guidelines for further use.
Monitoring the properties of selected industrial oil cutting fluid The research carried out in the last several years indicates that the use of industrial oils leads primarily to the reduction of their purity.

In the present study, the ARB process was performed up to 4 cycles with 66% reduction in thickness and the produced strips were air-cooled after roll-bonding.
The data points were fitted into a line.
Furthermore, the dislocation configuration turns to low energy dislocation structures and significant reduction occurs in the total strain energy associated with dislocations at large strain.
This shows that by introducing extremely high strains at low temperatures, the dislocations movement is constrained leading to formation of dislocation walls determining the reduction of the X-ray diffraction coherent domain from 456 to about 63 nm.

These new systems present comparative advantages: no additives are needed to promote precipitation, a costly magnetic alignment step is not required and it is easier to obtain efficient magnetic coupling due to the reduction in the number of involved phases.
This trend was motivated by the cost reduction derived from using the more abundant and inexpensive MM.
Based on the experimental data, it could be thought that a paramagnetic site should have been included for the x= 1 spectrum.
Besides, increasing the RE content led to a reduction of BHF, as observed in x= 1 ribbons.

While when the power of Ni range from 20 to 60 W, the Rq for the sample shows a obviously reduction compared to pure NbN coating (S0).
Therefore, in this work, we believe that the NbN/Ni coatings with various Ni content have similar reason for the reduction of surface roughness of NbN coatings.
However, with further increase of Ni powers, the values of H3/E2 go down quickly which could be due to the significant reduction of hardness in these coatings.
In order to further research the tribo-film of the NbN/Ni coatings, the EDS data of the wear track for the NbN/Ni coating (S2, 40 W) was acquired after the tribological testing, which is shown in Fig. 6 (b-c).

These e- and h+ can further take a role in reduction and oxidation process of pollutant [11].
The decrease in MB absorbance is in line with the reduction in concentration.
The data of total degradation efficiencies of MB can be seen in Table 1.

To the major advantages belong the insulation properties (acoustic, thermal, vibration) and weight reduction [1 – 3].
Flow curves for the specified temperature and velocity boundary conditions were plotted based on the data from [10].
Probably the reduction of time step can clear the temperature gradient pro simulation step in a run.
