Introduction Hydroxyapatite (HA) is known to be both a biocompatible and bioactive material, however, due to its poor mechanical properties it is not suitable for applying as a load bearing implant [1].
It has been shown that the bone-formation supporting capacity of any biomaterial is determined by its physiochemical and surface properties [3].
Many studies have established that specific surface topography is an important factor in regulating cellular adhesion and osteo-integration; and may be used to manipulate cellular interactions with biomaterial surfaces [4].
Form Index 3.19 2.37 2.30 2.15 0 1 2 3 4 Titanium Substrates Aspect Ratio Titanium HA Grooves Titanium Grooves Titanium HA NO Grooves Titanium NO Grooves The results of this study demonstrated that micro-channel surface features modified with HA clearly facilitated an elongated morphology utilizing the bonding properties between the cell's plasma membrane and the absorption of higher concentrations of calcium hydroxyapatite surface [7,8].
Micro-channel dimensions in this range may control the pitch of osteoblast actin stress fibers with an increase in cellular stiffness, and therefore affect the strength of adhesion [11].

In the silicon-containing base material and process of the alkali silicate and generated (Na2SiO4) are substances having adhesive properties.
Alkali treatment conditions conducted a preliminary exploration, discovery alkali concentration is the main factor affecting the performance of the adhesive remains to be further study the best conditions.

This method aims to improve decision-making in the construction industry by integrating multiple expert opinions into a single, quantifiable framework. 1.1 Problem Statement The problem that this research addressing arises from the need for including more than one decision maker because the factors affecting decision making process stem from more than one field of expertise.
Analyzing the problem: Identify relevant human, data, and domain factors. 2.
Model and algorithm selection: Choose a model and algorithm based on the factors identified in Step 1. 3.
ANNs and SVMs are prominent for forecasting concrete's fresh and hardened properties, showing robust performance.
Modeling of mechanical properties and bond relationship using data mining process.

The mechanical properties of traditional Al-Zn-Mg-Cu alloys can be further improved through increasing alloying elements (Zn) solid solubility or adding alloying elements (Ni).
All the time, studies for spray formed 7XXX aluminum alloys were focused on strengthening mechanism and mechanical properties.
Usually, little considerable attention is paid to porous defects, owing to the difficulty of characterization methods and numerous influence factors.
Several gas pores affect each other to form interconnected pores, which hold the morphology of gas pores and smooth surface (Fig. 3).

In the aerospace industry, factors like quality, safety and reliability are extremely important, because deficiencies in these can have devastating and costly consequences.
-Who is affected by the problem?
-Who is not affected by the problem?
The other parts manufactured with the same clamps was not affect
One of the most important process in aerospace industry is traceability control of each product, from final assembly up to the material mechanical and chemical properties resulted from manufacturing testing plan.

Due to the AM technology used and the type of material it is possible to achieve different properties of the produced parts.
The main of this research was evaluate the limitations of the printing material, to rule out factors that do not contribute significantly to print accuracy, and to provide a practical, quantitative guide for accuracy measurement as an engineering tool.
The orientation of the model in the print space affects the material used and the print speed.
An area affected by a large amount of slide will deform the affected side of the model.
There was a deformation that affected the surface quality of the model.

In this work, four sets of experiments were designed and carried out to explore the influence of various factors including the amount of copper, the reaction temperature, and the concentration of H2O2.
How does the amount of copper nanoparticles affect the surface morphology was investigated by fixing etching solution and etching time.
Generally speaking, temperature plays a positive role which affects the surface morphology and the etching of silicon.
Actually, the concentration of H2O2 and HF affects not only the etching rate, but also the morphology of the etching structures.

Injector nozzle multiphase flow numerical simulation of high pressure common rail system Yan HU, Guoxiu LI School of Mechanical Electronic and Control Engineering of Beijing Jiaotong University Beijing 100044, China Keywords: Injector nozzle, multiphase flow, CFD, Structural parameters Abstract.
The changing of injector nozzle structure will influence the combustion and emission properties in diesel engine.
Introduction Slight changes in the geometry structure of the nozzle can significantly affected the combustion and emissions of diesel engines.
Over the entire calculated region, the turbulence was so strong that the parameter values on the outlet boundary did not affect the results, and there was no available measured data.
In order to increase the injection rate, the first factor we may considered is the pressure of the fuel system.

Figure 1 Surrounding of the building to be explosion Main points about removal Determine the key and difficult of remove According to the project structure, level, height and geographical location, the main choice of how to demolition is blasting, mechanical, manual removal is auxiliary.
According to analysis about shear wall structure, the wall is connected with the main structure, it can not completely removed, so must leave wall column in special place when pre-removal the shear wall, to be not affect the stability of the overall structure of the building.
Blasting tests should be carried out before implementation, in order to accurately adjust the charge.Tests should not affect the structural stability of the building.
Slump vibration assessment In comparison with the blasting vibration, general building (weighing thousands of tons) dumped touch the ground generated vibration to the surrounding environment has more threatening and destructive.While this building near the surrounding buildings, but because the program used three-block blasting from before to after extension of detonation technology,the building blocks of the body will be lying on the ground partition.When building blast, network is taken to made five paragraphs touching the ground in turn,each touch to ground with the maximum mass about 1.5 × 106kg,the center of gravity height about 26m(fifteen floor roof height about 52m),calculated the shock velocity is 3.3cm/s at the 35m, slightly larger than the safety standards.Because the building is sub-detonate, when touch the ground the inside cut steel anti-support and front and rear beam slab pull force and other factors will to further reduce vibration.
The damage may be affected after dumping to underground pipelines,may covered sandbags for protective before blasting to reduce its direct impact ( is shown in Figure2).
