In this study, the method of immersion has been carried out for 21 days (retrieval of data is taken every 3 days) at concentration which has the highest efficiency based on the calibration of potentiodynamic polatization.
It shows that the MP extract inhibitor enable to slow the corrosion rate in the sample even though it is still a reduction in weight of the sample.
This indicates that the formation of the passive layer by MP extract can lower the corrosion rate so that the specimen weight reduction in the inhibited system is not much more than the system without inhibition.

When the angle of the movable blade change, the air volume, air pressure and power will also change, and the fan performance curve shifts [1,2] which has a very broad aerodynamic performance coverage range to adapt the complex working conditions ,energy efficiency and noise reduction.
Open the Fluent software, set procedures such as fluid data, solver, boundary conditions by selecting the 3D solver and reading mesh and finishing the analog computation of Fluent software.
Because value of turbulent flow is larger, it is prone to produce wind pulsation phenomenon and cause a serious impact on the fan components (such as wind wheel and impeller) and the entire system, and also can reduce the actual load and the efficiency of the blades, resulting in great reduction of efficiency of the fan, thus, the situation in left situation is not conducive to the service life and efficiency of fan.

Other investigated applications of Si1-xCx include: reduction of contact resistance [3], suppression of dopant diffusion [4] and improving the thermal stability of silicides [5].
Many properties of Si1-xCx epilayers vary as a transition between the properties of Si and 3C-SiC such as the reduction of the lattice constant and increase in bulk modulus [6].
This drop occurs up to a certain threshold C composition (approximately 10%) after which the bandgap is expected to rise up to the value of 3C-SiC, although there is currently no experimental data to support these simulation results at C contents this high.

Introduction Magnetron sputtering is widely used to deposit thin films of ferromagnetic materials in the fabrication of semiconductor and data storage devices.
Due to the reduction of thickness, the material needs less magnetic flux to reach saturation flux, as a result PTF increases.
(3) PTF increases linearly with the reduction of material thickness.

The data obtained in this study, clearly demonstrate that the strong inhibition of microbial growth was detected for all cotton textile samples treated via sol-gel method with zinc acetate dihydrate sol of the tested concentrations (Fig. 1).
After 24 h incubation, a tendency in the inhibition effect reduction was detected for bacteria with an increase of a temperature during post-treatment.
The results showed that the washing of the treated samples lead to the reduction of the antimicrobial effect.

It is a strategic product to help the automakers satisfying safety needs and fuel reduction requirements by means of the lightweight design concept, a current trend for new vehicles [1].
An oxide layer can be observed after the hot stamping which is beneficial as it prevents the reduction of the Zn by evaporation.
The GDOES is a useful technique to diffusion analyses, once it gives data input to follow the diffusional process in hot stamped steel.

Based on discretization of the measured data, the significance of attributes among rough sets was estimated instead of weight determination, and a relation data model about the durability effecting factors of concrete structures was established.
Then we can obtain the original data matrix.
Data standardization.
Calculate similarity coefficient rij=R(xi, xj) between each test sample using standardized data and establish the fuzzy similar matrix.
In order to find the importance of a division index ci(i=1, 2, …, m), remove the index and obtain the data matrix.

The study uses the data from a coastal forest catchment.
i ix y i n= be a set of collected accident data.
There are many methods to pre-process data, such as data cleaning (cleaning incomplete, noisy, or inconsistent data), data integration (integrating different data sources), data normalization (scaling data value in a range, such as [0, 1]), data reduction (reducing huge dataset to smaller representation), etc.
This paper adopted data cleaning to pre-process meteorological data.
The original rainfall data is used as the predicted variables.

It is substantiated that in the alloys of a new generation of ALTEK type, the use of homogenization and quenching operations is inexpedient, which implies the possibility of a significant reduction in the cost of heat treatment in comparison with industrial alloys, such as 1201.
Although there is no data about the structure of the four-component Al-Cu-Mn-Zr system diagram in the literature, the distribution of the phase regions in the aluminum angle of this system in the solid state can be predicted, based on the available information.
The calculation shows that copper presence effects but little the degree of this increase that is demonstrated by polythermal sections shown in Fig. 1, as well as the data presented in Table 2.
Though in literature there are no data on building a diagram of 4 – component Al–Cu–Mn–Zr system, phase zones distribution in the aluminum angle of this system in solid state can be predicted based on the existing information.

With these data the stress distribution and the lifetime of the components can be calculated.
Increase of high strength and multiphase steel during the past few years and the ongoing reduction of conventional deep drawing steel grades Fig. 10.
The mixed material approach steel, aluminum and plastics in terms of dynamic and axle load distribution at the new BMW M6 One of the most sophisticated mixed material solution as a result of weight reduction, dynamic and axle load distribution is to be seen in fig. 10.
Due to demands from the design department and weight reduction the front fender is made by thermoplastic (weight reduction: -4 kg/car) and the trunk lid (weight reduction: -2 kg/car) is made of thermosetting material for the same reasons.
Application of tailored rolled blanks in a floor panel as a cost effective solution for weight reduction the possibility to create ribs where necessary makes it cost effective.
