According to the main results [6], based on experimental data and Computational Fluid Dynamics (CFD) studies, it was concluded that it was possible to combine in a single device, high separation efficiencies with low Euler numbers (Eu).
In turn, the anticlockwise rotation has also played a favorable effect on the Euler number, with average reductions 12.3% compared to conventional separator H11 (0 rpm).
The smallest Euler number was reached when the largest anticlockwise rotation was used in hydrocycloning (3000 rpm) leading to a reduction of approximately 17.1% in the analyzed response.
According to the experimental data of underflow-to-throughput ratio for the hydrocyclone under study, it can be seen that neither the direction nor the intensity of rotation has played significant effect in this response.
In turn, the clockwise rotation played an adverse effect on the overall efficiency, with an average reduction around 18.3%.

Time-resolved fluorescence spectroscopy data showed a picosecond ultrafast electron transfer process from CdS-NPs to the graphene sheet, which demonstrates the potential optoelectronic application of this graphene–CdS hybrid material.
These data indicate that graphene-supported Pt-Ru may be an ideal candidate for direct methanol fuel cell electrodes.
The above data also clearly support the proposition that Pt-Ru NPs can effectively advance the oxidation of methanol to CO2 and inhibit the accumulation of CO and other carbonaceous species formed on the graphene and carbon black electrodes.

In addition, the obtained numerical results are compared with the experimental data.
The strain diagram was constructed on the basis of experimental data [8, 9] in a wide range of temperaturesand strain rates that do not cause additional temperature changes in the material.
In addition, the work of J D Stachiw was analyzed [4], which shows the results of full-scale experiments on loading the capsule and presents data on the reduction of the total volume of the sphere at the corresponding hydrostatic pressures (see Table 2).
However, the numerical results, in comparison with the experimental data, showed, on average, 1.5 times less change in the internal volume.
After verifying the constructed model with experimental and analytical data, it is advisable to predict the performance of the capsule at.

The extent of this strength reduction depends on whether coarse or fine aggregates are being replaced.
It is estimated that around 780 million tonnes of raw steel fibers (assuming 20% steel content in tires) could be accumulated from thirty-two states (EU28, Norway, Serbia, Switzerland, and Turkey) based on the 2018 data on tire waste [55].
This reduction can be attributed to the melting of CR at 200°C.
Overall, the data suggests that increasing CR content does not markedly influence the impact resistance, neither at the stage of initial cracking nor at ultimate failure, when WSF is present.

It was found that in the hot band of this high purity Al, cube orientations were mostly rotated away into other orientations due to low temperature hot rolling with high rolling reductions.
In discussing such a localized process, the statistical reliability of the experimental data plays an important role.
It turned out that, at such high rolling reductions, orientation distributions within a grain were in all cases rather uniform, giving the maximum orientation spread of about 15 º.
Thus, most of the {100}<001> regions observed in the hot bands seem to have rotated away into other orientations during heavy cold rolling of 98 % reduction in thickness.
Very thin layered deformed microstructures and high stored energy established by heavy cold rolling of 98 % reduction in thickness seem to have enhanced such preferential growth of cube recrystallized grains.

To accurately control the Si content and ensure the function of slag refining in high aluminum steel, the direction and limits of reduction reaction for SiO2 were analyzed based on the thermodynamics.
Using simplex method, the experimental data was changed into a triangle form.
Fig.7 shows that when the alkalinity is greater than 1.5, a significant reduction of aSiO2 appears.
While content of SiO2 is less than 4%, SiO2 do not be restored basically; While content of SiO2 is 10% and 20%, reduction amount of SiO2 reaches 38.6% and 40.7% due to high activity of the slag.

So, as long as the data about customers' interests and preference are maintained and the customers with similar taste are analyzed from the data, the recommendation can be made according to the comments given by customers with similar interests.
Another way is to spend time on searching users' data and then group the users and recommend for them after a while.
The data in the rating matrix is sparse.

The content of SiO2 was more than 60% in the residue of pyrolusite detached manganese by reduction roasted and acid leached, and it was a better siliceous raw material because of less other impurities.
The experimental datas were well interpreted with a shrinking core model under chemical control.
The present study focused on pyrolusite slags from pyrolusite detached manganese by reduction roasted and acid leached processes.
The simplified equations of the shrinking core model when liquid film diffusion, ash/inert solid layer diffusion or the surface chemical reactions is the slowest step can be expressed as follows, respectively [11]: (2) (3) In order to obtain the kinetic parameters and rate controlling step, the experimental data was analyzed on the basis of Eqs. (2) and (3); and the experimental data validity was verified by statistical and graphical methods, the multiple regression coefficient obtained for the integral rate expression were calculated.
The results showed that the kinetic datas from the temperature studies were fitted to Eq. (3) and the correlation coefficients (R2) were greater than 0.96.
