However, from the viewpoint of soft tissue integration, it remains to be elucidated whether or not surface topography affects the soft tissue attachment around implants.
Under systemic anesthesia at 4 weeks after implantation, cotton ball was immersed in HRP dissolved in isotonic saline (50 mg/ml), and then laid on the gingival margin around the implant body without imposing any mechanical stress.
In addition, surface topography is reported to affect the collagen fiber orientation in the connective tissue.
Considering previous reports and our results, we can speculate that soft tissue cell response to titanium surface itself is not the dominant factor for sealing capability against foreign body invasion around dental implant.
Conclusions From the viewpoint of the prevention of foreign substance invasion, soft tissue around Rs implants showed stronger barrier property than that around Ms implants.

Introduction Age-hardenable Al-Mg-Si alloys have attractive properties such as good formability and high corrosion resistance.
The Al-Mg-Si alloys are well known to be hardened during a paint baking process at around 170 °C for 1.2 ks in the automobile manufacturing process, resulting in the improved mechanical strength.
This is the natural aging and results in the positive or negative effect on the bake-hardening(BH) response[2,3].The complicated changes of the nano or micro scale structures in the matrix such as nanoclusters or GP zones during natural aging markedly affect the BH response[4].
Based on these results, it is clarified that the Mg/Si ratio of the alloy composition is a significantly important factor in the nanocluster formation.
The electrical resistivity is strongly affected by the amount of solute atoms in the matrix due to the nanocluster formation [14].

Meanwhile, a higher absorbed dose can result in the HDPE particle decomposition, affecting their mechanical properties.
The degree of non-linearity between the dissolved ions concentrations and the adsorption was tended to from the heterogeneity factor (1/n).

Combination of small size and high Q factor empowers these devices with excellent detection capability [4, 5].
Modeling nanoparticles by a layer around the ring, running the simulation, and then changing its thickness with the corresponding refraction index of the particles will affect the resonance response compared to the resonator without the layer.
The distance between the ring and straight waveguides, where the coupling effect takes place, has been optimized as 1.20 µm based on the Lorentzian line intensity, iii) Material properties have been specified such that refraction index for the core and cladding part of the resonator fiber was set to be 2.5 and 1.5, respectively, iv) Extremely fine-size triangular mesh has been chosen to perform a detailed computing through finite element method, v) The simulations have been run sequentially to determine the optimum ring size (ring radius ranging from 83.00 µm to 83.01 µm with constant RI), titanium dioxide nanoparticles (ranging from 10 nm to 100 nm with effective RI) , and protein molecules (ranging from 10 nm to 100 nm with effective RI) using Yamaguchi model approximation for effective refractive index calculations, and vi) The simulation results have been processed by Matlab software tool to create the corresponding graphs.
The impact can be seen more clearly from the following expression, ∆λrλr=ΔRR+Δneffneff (2) Increasing the radius of the ring leads to a red shift in the position of the affected resonance wavelength.
It is also worth mentioning that the challenges for reliable optical micro-resonator sensors exist including i) the sensitivity of resonance frequency to temperature and refractive index fluctuations, ii) control of the distance between the resonator and the straight waveguide, and iii) fabrication of integrated chip-scale devices with excellent mechanical stability.

In a mechanical stack, the junctions are fabricated separately.
These factors are aimed at minimizing losses using various techniques.
It is favored for its good quality, carrier transport properties, thermal expansion, and compatibility with different semiconductor materials in terms of lattice constant [9].
But, it is more difficult to adjust the voltages, because the voltages are intrinsic properties of the material.

The properties of the tools shown in Table 2a are characteristics of commercially available powders (HTCS1) with high thermal conductivity that are used to manufacture tools with the L-PBF (Laser Powder Bed Fusion) technique.
The presence of such supports is not recommended as it can adversely affect the flow conditions inside the channels [18].

Introduction Messier-Bugatti-Dowty aim to produce landing gear which supports the aerospace industry’s drive to reduce the environmental impact of air travel: by improving the corrosion properties and reducing the weight of their landing gear, which is currently mostly made from high strength stainless steel [1].
One way to implement these changes is to alter the landing gear material; titanium alloys have better corrosion properties and better strength-to-weight ratio than stainless steel so they are an obvious alternative.
The graphite foil also protects the die and punches from mechanical damage.
This is an advantage as grain boundary alpha detrimentally affects ductility[12, 13].

It concerns knowledge that was pre-defined by domain experts (that affect complex object diagnostics) or processes for which the development of numerical diagnostic models and object models is not sufficient or possible.
The uncertainty can occur due to various factors that influence the results of data acquisition process.
The main factors can be · irrelevant data (insufficiently dependent on the state of the object), · approximate data (expressed in a qualitative manner), · contradictory data (distinct opinions of specialists), · inaccurate data (measurement errors), · incomplete data, · incomprehensible (expressed in an ambiguous manner).
Research on this particular subject has showed that constructing complex statements of an excessive number of variants does not lead to obtaining better reasoning results but increasing the number of necessary parameters, e.g. the size of conditional probability tables used with belief networks which worsens generic properties of such models.
Developing an unequivocal and semantically consistent knowledge base is one of the most important stages in the diagnostic system design process and one that affects the system efficiency.

Miller [4] proposed a yield surface that can be fitted to the plastic flow properties exhibiting plastic compressibility.
In the present paper, a factor of 0.01 with the modulus of the resin is used to deteriorate the stiffness of the failed lamina[13] (the choice of the degradation factor is presented in reference [13]).
Further on, the present study takes skin effect into account that varying geometrical parameters of face layer and core layer affect nonlinear response and ultimate strength of honeycomb sandwich composites.
