Thus it
can be an attractive candidate material for drug delivery in bone related disease, since the carrier may
have little chances of thermally affecting the loaded drug.
U.Gbureck et al.[3] analyzed the various factors affecting the shelf life of bone cement such as starting acidic component, milling condition and atmosphere during storage.
The formation of DCP instead of DCPD affects the properties of β-TCP based cement in many aspects.
The decrease of density also affected the mechanical properties of cement.
Conclusively, in spite of the excellent biocompatibility and biodegradability of β-TCP based cement, storing condition of the cement is found to strongly affect the properties of cement such as setting time, temperature rise and compressive strength.

Experimental results
Mechanical properties.
Besides, the percentage variation of the mechanical properties is reported in Table 3.
We could conclude that aging affects only the FRP mechanical properties and not the FBG optical properties, also not reducing the interfacial FRP-FBG adhesion.
After producing specimens, mechanical and metrological tests have been performed, in order both to characterize the device and to evaluate if the presence of the sensor could affect its mechanical properties.
At last, accelerated aging does not influence FBG sensor optical properties while it reduces FRP mechanical properties.

The main factors affecting the stress and strain fields are the shape and the size of the buildup, the process parameters, the thermomechanical and the thermophysical properties of the deposited material and the interlayer dwell time [8, 15, 16].
The temperature-dependent thermomechanical and thermophysical properties for IN625 and AISI 316 were taken from [8, 19, 20].

Recently, NIR have applied extensively to estimate wood properties, wood processing, modification
and wood composites[1,2].
The absorption peaks of wood density in NIR region deeply affected by various factors, such as structures, ages, directions or different parts of a tree.
Wood density is a measure of its gross porosity, which has an important influence on mechanical and other physical properties of wood.
The air-dry density of larch samples were measured in accordance with the Chinese standard "Physical and Mechanical Properties of Wood Test Method" (GB1933-1991).
Conclusions The hydrogen groups in wood reflect absorption peak of different characteristics in NIR, which can accurately eatimate the properties of wood.

CMP is a high efficiency process, both due to the varied chemical and physical properties of the surface materials.
So chemical reactivity appears to be an essential factor of CMP process.
This result suggests that fullerenol molecules absorbing onto the copper surface affect the high efficient material removal.
In our conventional study, it is cleared that chemical reactivity of fullerenol is essential factor for the removal of copper [2].
Structural differences of the fullerenols affect the aggregate formation.

This terrible environment makes revealing the impact of metallurgical and environmental factors on the corrosion depth and predicting the corrosion degree more difficult.
BP neural network has been exploited to analyze the non-line relationship between various factors and material corrosion behavior for many years [2].
Some previous network models focused on the corrosion properties of conventional steels exposed to inshore atmospheric environment [4-6], but little attention was paid to the recently developed bainite steels corroded in the offshore platform circumstance.
Chemical compositions and mechanical properties of these steels are listed in Tab. 1 and Tab. 2.
The environmental factors (including average concentration of sea salt particles, corrosion cycle, average temperature and humidity) as well as the metallurgic factors (including the contents of C, Mo, Cu, Cr, P, Nb and Ni) were chosen as input parameters.

The
factors influencing the natural characteristics of the saw-blade were also discussed.
In this paper, the influencing factors to natural characteristics of the blade, core thickness, rotary speed, clamping ratio and core diameter, were quatitatively studied by FEM.
The core material of the saw-blade is spring steel 65Mn, and its properties are listed in the Table 1.
The influencing factors to natural characteristics of the blade core were respectively analyzed.

Due to its excellent mechanical properties, such as high stiffness-to-density and high strength-to-density ratios, AA6082 is suitable for structural sheet-metal fabrications [1].
A novel process, solution Heat treatment, Forming and in-die Quenching (HFQ®) has demonstrated its advantages in the forming of AA6082 TWBs with improved formability, as it could eliminate the welding effects and restore the mechanical properties of the welding zone [3].
The model makes use of a non-homogeneity coefficient, or imperfect factor, which accounts for the initial discrepancy in the thickness.
Since HFQ® forming technique could eliminate the welding effects and restore the mechanical properties of the welding zone, no special consideration was taken for the weld zone and the weld line mesh was set to the same as that of base material.

But the defects in ZnO crystal are the key factors for restricting the luminescence properties of the material.
After annealing treatment the optical properties of ZnO thin films were characterized by photoluminescence (PL) with a laser using an excitation wavelength of 351 nm and a 100 mw power.
Summary At present, the research of ZnO is a hot spot, it is expected to be ultraviolet and visible light emission materials at room temperature or higher temperature because of high chemical and mechanical stability and excellent photoelectric properties, substituting for the current industrialized GaN material.
But there are always some defects in materials due to the influence of substrate and the growth condition in preparing process, which affected the properties of ZnO materials seriously.

As the optimization model is a minimization problem, the negative mean admissible stress has been included in the objective function affected by a weighting factor w.
Computational time has not been a major concern within the scope of this research and the maximum numbers of iterations and function evaluations have been set to Inf (infinite) in MATLAB, so these criteria are in practice removed without affecting the convergence of the algorithm.
Their mechanical properties (K, n and tensile strength σu) are listed in Table 1.
Mechanical properties of workpiece materials.
These values could seem very restrictive, but they provide very good results without affecting the practical convergence, in terms of time, for the IPA.
