Especially, alumina/alumina total hip arthroplasty has shown its very low-wear property.
Therefore, it is possible to control the residual stress in the alumina matrix, which strongly influences the mechanical properties, by controlling grain size, or in turn, by sintering temperature.
The change in the residual stress field of the alumina matrix and in grain size with changing sintering temperature did not affect phase stability under water vapor conditions.

Besides the study on strength properties and mechanism of the reinforced soil (Haeri et al. 2000, Michalowski 2004), the influence of the kinds of reinforcement materials and reinforcing styles on strength has been investigated.
The corresponding safety factors and factored shear strength parameters of soil are presented in Table 3.
Furthermore, the structure has a smallest safety factor in horizontal reinforcing case, while it has greater safety factors in horizontal-vertical and joint frame reinforcing cases.

Alloying with Mn or Ni has a strong influence on the electronic configuration and magnetic properties of the austenite and therefore on the SFE.
Their excellent mechanical properties have been a matter of study, and their relation with SFE is a key factor.
In general, alloying with Mn or Ni as has a strong influence on the electronic configuration and magnetic properties of the austenite and affects as well the influence of the interstitial elements on SFE.

Through the analysis with the modal theory, it is clear that each order of the system's natural frequency dependents on the mass matrix and stiffness matrix, when the two kinds of matrix are fixed, each order of the mode damping ratio is only affected by the damping matrix.
From the whole structure layout, the column-beam-wheelhead-carriage subsystem is the main factor affecting the whole grinder's dynamic characteristic [2].
Before the mesh division of the 3D model, the proper element property must be firstly defined.
In general, the vibration of the whole grinding machine usually has not seriously affect the quality of grinding, so under the frequency of these orders, vibration mode should be neglected in the improvements.

Unfortunately, composite structures show a very complex mechanical behavior concerning dynamic loads and a variety of damage mechanisms, that are hard to predict.
Here, thedesign variables are assumed to be an additional element property that can be understood as a relative density of the element.
The values of the penalization exponents p and q are problem-dependent, but a penalization factor of about 3 is generally proposed in common literature [8].

With social variables equal in the two communities, the influence of the environmental configuration is then implicated to some extent as a causal factor to explain the differing crime rates in the two communities.
There is little doubt that areas affect people as well as people affecting areas.
By incorporating seating areas, picnic areas, porches and other amenities in open spaces, the legitimate users will participate in the activity and maintain ownership of the property.
Security lighting Lighting is an important factor in controlling crime.
There are much more effective ways to ensure safety, such as caring neighbors who watch out for your property.

However, recent experiments revealed that the impact of a magnetic field is not confined to magnetically anisotropic metals but can also be observed in a material with magnetically isotropic properties.
According to the classical JMAK model of recrystallization [14-16] for homogeneous nucleation at a constant rate and isotropic nucleus growth the recrystallization time can be written as 1 1 4 4 v 3 N R 3 0 0 Q 3Q 3 t Nv exp 3 N v 4kT − +     π  = = ⋅      π       & & & (1) where N& and v are the rates of nucleation and nucleus growth, NQ& and vQ are the activation enthalpies of nucleation and nucleus growth, 0N& and 0v are the respective preexponential factors.
It is unlikely that the nucleation rate can be affected by an external magnetic field, since in particle containing Al-alloys nucleation is site saturated, i.e. occurs at particles at the very beginning of recrystallization.
It is known, however, that a magnetic field can induce the motion of dislocations without any external mechanical stress [17, 18].
Therefore, it is reasonable to assume that also the mobility of grain boundaries can be affected by a magnetic field.
