As one of the major factors comprising phagocyte transmigration, previous studies hypothesized that histamine might play an important role in the recruitment of inflammatory cells to implants [2].
However, the numerical solutions failed to symbolically show the direct relationship between the models parameters and could not also provide good and continuous insights into the significance of various process parameters affecting the phenomena.
Porous substrates and angiogenic growth factors can stimulate formation of microvessels, which, to some extent, can maintain analyte delivery to implanted sensors.
It is probably also necessary for other growth factors to act upon immature vessels to mature the fragile microvessels into more robust vessels.

Conclusively, fine size palm ash and coarse size palm slag show the better viscoelastic properties in rHDPE composite.
On the other hand, various researches also have been done to examine the properties of rHDPE.
Besides, it was stated that the rHDPE could have the same properties with the virgin HDPE.
The dynamic properties of samples were evaluated using dynamic mechanical analyzer (DMA) of Perkin Elmer DMA 7e model.
Conclusively, fine size palm ash and coarse size palm slag show the better viscoelastic properties in rHDPE composite.

In this paper the finite element method is used to analyze dipper handle and find out the weakness in the structure and factors impacting the service life of dipper handle.
Sometimes many factors on dipper handle structure have to be assumed and simplified, some difficult points are also neglected to satisfy with the calculation conditions in strength check [5,6].
According to structure properties and load conditions, fracture reasons of dipper handle had been found out by utilizing finite element model to analyze the stress.
Fig.5 Stress diagram of dipper handle Fig.6 Time history of dipper handle Improved dipper handle The original Q235 steel as material of dipper handle can not meet the nowadays requirements. 16Mn and 15MnV all have better mechanical properties which have almost the same market price.
But 15MnV steel mechanical properties are better than 16Mn steel.

Introduction Machine tool supporting pieces have greater affect on its dynamic characteristics.
By joining the stuffing, it not only can reduce resin content, reduce cost, but also can improve the physical and mechanical properties of the polymer concrete.
Accordingly, we can estimate factor by the resonant shape.
This is a common method of the factor determination by test.
When factor is very small (such as factor < 0.05), .

The knowledge of the physical and mechanical properties of the agricultural products is of fundamental importance for the correct storage procedure and for design, manufacturing and operating different equipment used in post harvesting main processing operations of these products [2].
Development of models to predict drying process has assisted in understanding the factors affecting drying process such as temperature, relative humidity and velocity of drying air and optimizes them for reducing drying time and saving energy without performing a large number of experiments [8].
In this context, it is clear that the fissure of rice is influenced by several factors, such as, temperature, relative humidity, and velocity of the drying air, and drying time.

However, the low efficiency and the high cost certainly affect its widely application.
Introduction Since EDM can be free of the affect from its material’s comprehensive mechanical properties such as hardness and brittleness, it is especially suitable for the conductive materials which are hard to be deal with conventional mechanical processing methods.
Generally speaking, with less the influential factors and comparatively clear regression model, a relatively more exact model can apparently be got by the regression techniques.

On the other hand, good mechanical properties can render machining of these materials difficult.
Originally developed for aerospace applications, its low density, high thermal conductivity and excellent mechanical properties at elevated temperatures make it an ideal material for aircraft brakes, rocket nozzles and re-entry nose tips.
The properties are very much dependent on the manufacturing methods used for production.
In this experiment, the influencing factors are: milling depth ap, feed per tooth fz, milling speed Vc and cutting width ae.

Corrosion behavior and formation of the passive film in 17-4 PH SS, produced via SLM, are influenced by a combination of factors, including composition, microstructure, and cathode reactions [6,7].
To fill this research gap, this study examines how variations in scanning speed, and hatch distance affect the microstructure, mechanical properties, and corrosion behavior of 17-4 PH SS parts produced through SLM.
The EIS results, depicted in Fig. 3d, were used to quantitatively assess the electrochemical properties by fitting into an equivalent circuit. 
The investigation systematically analyzed the effects of scanning speed (700, 750, 800 mm/sec) and hatch distance (0.08, 0.1, 0.12 mm) on both microstructural features and corrosion properties.
The solution treatment effectively homogenizes the microstructure, reducing visible defects and enhancing mechanical properties. 2.
