Determination the Parameters of Dissolution
The article determines the reaction series based on experimental data of dissolution in the mineral and absorption on the mineral surface.
When dimensionless distance is 0.6, diffusion coefficient is 0.1, 0.01 and 0.001, reduction of relative alkaline solution concentration is 47%, 21% and 11%.
When dimensionless distance ranges from 0 to 0.6, displacement velocity is 15ml/h, 10ml/h and 5ml/h, reduction of relative alkaline solution concentration is 33%, 23% and 10%.

This selection allows for leveraging various energy storage mechanisms, such as electric double-layer capacitors (EDLCs), which involve fast electrostatic ion adsorption (non-faradaic), and pseudo-capacitors, which utilize reversible oxidation-reduction reactions.
The Fe3O4/ ReS2 CV curve shows two smaller oxidation-reduction (redox) peaks.
An equivalent electrical circuit used for the EIS data fitting (see Fig. 5a), includes several components: R1 represents the equivalent series resistance, R2 is the charge transfer resistor, and Q is the constant phase element impedance.

Based on the tensile strength, impact toughness and field
application, the optimized holding times were determined as 30minutes in T922 and 60minutes in
T929 type welds respectively.
2) Hardness Reduction in HAZ.
As a result, it was shown that stress reduction factor due to this type IV cracking could be 50% for 100,000hours test.
In order to compare the effect of the filler metal on the creep strength, 105 hr creep rupture strengths for T23 [4], T91 [9], and two dissimilar weld joints were determined based on the average creep data and plotted with temperature in Fig. 6. 105hr creep rupture strengths of T91, T23, T922 type, and T929 type dissimilar welds at 600o C were 97.2, 94.6, 93.8, and 88.7MPa respectively.

The researches related to our research include two aspects: carbon emission reduction strategies and design of online channels.
Due to less ship size and long distance, hence, efficient logistics networks play more important role to carbon emission reduction than fuel efficiency and size of loads.
Tedeschi: Compressed data; big companies go slowly in devising net strategy.

The catalyst used in this study is free from preceding reduction in hydrogen.
They explained this result by the fact that the degree to which metallic iron accumulates upon reduction into metallic particles depends on the iron content.
We also measured the outer diameters of 28 MWCNTs formed by 1Fe3O4/MgO catalyst and the data was presented in Fig. 6b.

Excellent light diffusion and reduction of solar transmission .
Nanosensors and Smart Environments: Initially, building components will become smarter, gathering data on temperature, humidity, vibration, stress, decay and a host of other factors.
suggests that 40 % of the energy savings required to achieve necessary carbon reductions could come from the building sector, Better building envelope design, daylighting, more efficient artificial lighting, and better efficiency standards for building components and appliances are all opportunities to make the building industry the leader in fighting global climate change and advancing sustainable development and energy conservation.

The first method reported in the literature to produce shear property data was developed by Iosipescu [1].
This analysis shows that a concave (Rl>0), in opposition to rectangular (Rl=∞) and convex (Rl<0) geometry, leads to reduction of strain concentrations near the specimen shoulders.
The reduction of the gauge area of the sample allowed a significant decrease of the clamping force, and, consequently, sliding was avoided.

Dynamic light scattering (DLS) is a technique used for measurement and interpretation of light scattering data on a micro second time scale.
On the other hand, the nanofluid prepared with physically functionalized MWCNTs, by the addition of Gum Arabic surfactant produced a reduction in the thermal conductivity of the base fluid by 18.96% which is represented in Fig.6.
However in this case since most of the nanoparticles underwent agglomeration with particles of same nature and with the foreign particles of basefluid, large scale sedimentation took place which in turn caused the reduction in thermal conductivity of the distilled water.

Some reduction in the chromium content allows the introduction of elements that contribute to the improvement of the complex properties at low temperatures.
The introduction of vanadium together with nitrogen leads to the grinding of the dendritic structure, hardening of steels by dispersed particles, and the reduction of the embrittlement effect of nitrogen [26-27].
The obtained data on the MAS efficiency made it possible to draw the following conclusions: According to the table, the bodies of steel 07X13G28ANFL have higher properties and withstand a higher internal pressure compared to the bodies of cast steel 12X18N10TL.
