Titanium alloys are standard materials in dental implants providing a combination of mechanical strength, chemical stability and biocompatibility [1,2,3,4,5,6].
The main factors influencing the biocompatibility of biomaterials are chemical composition, mechanical properties, electrical charges, and surface features [4].

Some studies suggest that the OLTC transformer is considered as one of the important factors which causes voltage breakdown[9].
Currently, some studies on the voltage stability of power system affected by OLTC are mostly based on the OLTC of the mechanical tap-changer of tradition.
Now the contactless OLTC circuit using the transition resistance or reactance also brings circulation and affects voltage stability.

The tooth profile modification parameters mainly consist of three factors: the maximum profile modification amount, the length of profile modification and the modification curve form
The modification object is pinion by practical engineering application and cost factors that takes the data into account.
In order to avoid affect the installation of the gearbox, thus improved structure on the inner of the cover.

This article looks at recent research on SCC of duplex stainless steels and the different facets and factors which are relevant to the topic.
The sigma phase formation was the most detrimental factor on the corrosion resistance.
In this context, the effect of "475 ⁰C embrittlement" on the corrosion properties and SCC resistance of DSS should be discussed.
In addition to a loss in mechanical properties, the presence of multiple phases and interfaces play a significant role in the corrosion resistance of DSS.

It is presented in literature as a biomaterial that presents the potential to regenerates soft and hard tissues because of their appropriate mechanical, physical and biological properties like strength, elasticity and an excellent metabolic biodegradation rate with no toxicity of liberated metabolites [1].
Experiments show that chitosan does not affect the structural arrangement of collagen.
It is known that properties like: water absorption, viscosity, traction resistance, deformation and individual biopolymer morphology are found in blends in a controllable way, depending on their proportions in mixture [1].
We could observe that the porosity was a major factor to observe significant calcium phosphate deposition on a chitosan-collagen blend membrane, revealing a more intense in vitro calcification on porous membranes. 5 References [1] Tonhi, E.

In the analyses the socketed depth of piles, the properties of soil and rock mass, the scale, space position and filling situation of the Karst caves and the features of the contact interfaces between piles and soil and rock mass were taken into account.
To the working mechanisms of the rock socketed piles, some theories and principles were put forward [6~12], within them it is generally accepted that the characteristics form the load-transfer to failure of the rock socketed piles are related mainly with the ratio of length to diameter of the pile, the depth and the property of the Karst overburden, the rock properties of socketed section, the socketed depth into rock, the piling technology, etc.
The physical and mechanical parameters of the earth/rock in the numerical model are come from the survey report, using rational reduced average values.

It is essential to predict and control these characteristics through the chosen AM process, and to ensure mechanical performance that is at least comparable to the existing one.
However, other factors may contribute to porosity, such as pure CO2 acting as a shielding gas that dissociates to release oxygen and increases the risk of oxidation [5].
