The structural and electronic properties of perovskite nanoparticles are affected by the orientation disorder of A groups, while their optical properties depend on the nanoparticle size and the types of cations and anions [20].
The arrangement of B-site cations significantly affects the electronic and magnetic properties of perovskites, impacting magnetic coupling and band gaps [21].
The enhanced microwave attenuation is attributed to several factors such as interfacial polarization, selective distribution, multiple scattering, and capacitor-like interfaces.

Zuckerdolomit may occasionally respond to mechanical impulses with a complete break down of its structure.
Moreover, taking into account the elastic constants for both minerals, which differ approximately by the factor two, the special geomechanical behaviour of the studied Zuckerdolomit appears to be considerably determined by interactions between its residual strain and textural properties.
This lithic type of Zuckerdolomit is feared by miners and engineers because, in the case of changing mechanical load (impulses), a complete collapse of the grain structure, followed by rock liquefaction and catastrophic ingress of mud streams was frequently observed.
Residual stress, the structure of rock complexes and their textural properties are of great importance for the estimation of rock behaviour within deformation processes.
Concluding from these observations we may suppose that petrophysical features of the (studied) Zuckerdolomit may affect its geomechanical behaviour to a greater extent than assumed so far, especially in comparison to the importance of anhydrite hydration.

The experimental scheme that a large number of factors are involved into needs to be rationalized and optimized with the Orthogonal design or Uniform design use conventionally by comparision with a small number of factors that usefactorial analysis[2-3].
In this paper, based on neural networks corresponding model of relationship between the laser machining parameters and surface quality was investigated and applied to predict the better combination of laser cutting design parameters for achieving optimum roughness. 1 Simulated Annealing and Neural Network The quality of laser cutting metal sheet has been affected by many factors including the laser properties, focusing lens properties, mechanical control systems, process materials and process parameters [4-6].
Because laser machining input parameters for optimization such as cutting speed, output power, gas pressure and other factors affected the quality of laser cutting for the existence of a variety of complex correspondence, which it was difficult to be explained from theoretical models and analysis.

Factors Influencing Corrosion Substances that cause corrosion of aluminum aerospace alloys are called corrosive agents.
Some factors that influence metal corrosion and the rate of corrosion are; type of metal, temper, grain direction, anode and cathode surface areas, temperature, humidity, presence of electrolytes, availability of oxygen, stress on the corroding metal and time of exposure to a corrosive environment.
Since the material of a component is subjected to corrosion, it is expected that its critical mechanical properties will vary with increasing service time, which must be taken into account for the structural integrity calculation of the component.
Many factors influence aluminum aerospace alloy corrosion such as type of metal, temper, grain direction, temperature, humidity and availability of oxygen.
Some common Al-Cu, Al-Zn and Al-Li aerospace alloys and their composition were given in a Table and some common types of corrosion affecting these alloys (General, Pitting, Crevice, Galvanic, SCC, Exfoliation and Fatigue) were discussed.

Co-crystal provides a new approach to tailor the physicochemical properties such drug solubility, dissolution rate, stability, bioavailability, hygroscopicity and mechanical properties while maintaining the biological functions of an API [1,2,3,4].
CBZ was of interest because it was one of the water-insoluble drugs; faced issues regarding its poor solubility, bioavailability, stability and mechanical properties [8].
Most of co-crystal solubility studies emphasized on kinetic measurements of dissolution [2] which are mostly influenced by factors such as surface area, phase transformation, particles size distribution, and fluid dynamics [10,11].
Thermal properties were analyzed using differential scanning calorimetric (DSC) at 10 oC/min heating rate under nitrogen atmosphere (50 ml/min).

Introduction With the growing shortage of resources and people's awareness of environmental protection,the waste concrete dispositions and recycling of waste concrete more and more get attention, Therefore the domestic and foreign scholars have conducted a series of studies for recycled aggregate grading, RAC material and structural properties [1,2,3], the conclusion is also different.
Because of ITZ especially the second ITZ are weak and complex, therefore the transition zone on the mechanical properties of RAC effects are far greater than the ordinary concrete.
This indicates that the old and new interface of RAC specimens is the most prone to crack, which are the weak parts , it’s properties great impact on the mechanical properties of RAC.

Experimental work shows uncoupled transfer functions vary over time and by enough to significantly affect squeal predictions.
Initial research focussed on using the frictional properties of the contacting materials to predict the occurrence of squeal.
While it is clearly important to understand the tribology of the system it is equally important not to neglect the surrounding system properties.

For example, Wiebenga, Atzema, An, Vegter and van den Boogard [17] examine the variation in the mechanical properties of 41 coils.
To date, most of the simulative studies concerning the influence of various parameters on the part quality indicate that the significance of individual factors vary depending on the part, part region and the state of other factors.
Previous variant simulations in sheet metal forming operate with dramatically reduced and simplified factors.
Steel manufacturers apply this method in the field to measure mechanical properties of running strips [24].
An explicit examination of the parts’ mechanical properties is not given, although a defect might have an effect on assembly.
