Nanofiber nonwoven has been used in many fields due to the high surface area to volume ratio of the nanofibers and other extremely excellent properties.
The methods included liquid reservoir collector[4], dynamic liquid system[5] , mechanical twisting [6], two rings collector[7] and conjugate electrospinning [8, 9], etc.
The possible reason might be that the charged jets were affected by a strong electric field.
Applied voltage is one of the important factors affecting on nanofibers in electrospinning.
Fig.4 Photograph and SEM micrograph of PVA continuous nanofiber yarn obtained in this experiments Mechanical behavior of the yarn was showed in Table 1.

The remaining factors, preheating time and interaction of preheating temperature and preheating time are not significant but preheating time is more influential factor towards the tensile strength than that of the interaction.
The analysis of grain structure shows that the size diminution is considered as one of the important factors for the fluent increment of tensile strength.
The circumstance was because of the incomplete bonding of the chips which straightway affected the mechanical strength of the extruded profiles at preheating temperature of 400°C and 1 hour.

Introduction With regards to their biological and physicochemical properties, titanium-based biomaterials have been successfully used in orthopaedic, dental and maxillo-facial surgery mainly as endosseous implants.
Clinical success has been achieved not only because of mechanical strength excellent biocompatibility of titanium alloys but also because of other characteristics such as surface properties.
Among them, surface roughness is one of the most acknowledged properties improving the bone anchorage of titanium implants [1-3], or to prepare implant surfaces for plasma spray Hydroxyapatite HA coating [4].
Discussion Surface Roughness is one of the key factors for the osseous integration of orthopaedic and dental titanium implants.
This sandblasting procedure has been proven to cause a contamination of implant surface which can have unfavourable affects on its bone integration [5].

According to Taguchi, quality characteristic is a parameter whose variation has a critical effect on product quality, e.g., weight, cost, target thickness, strength, material properties, etc.
The Taguchi quality strategy is to improve quality in the product design stage by making the design less sensitive towards influence of uncontrollable factors and Optimizing the product design.
These standard arrays stipulate the way of conducting the minimal number of experiments, which could give the full information of all the factors that affect the performance parameters.

However, the identification of the factors making health facilities vulnerable [2] is even more critical, since they rule the design of the SHF.
Such factors lead to the distinction among structural and non-structural safety issues and issues based on functional capacity.
The need of combining different sensors and analysis tools for an effective assessment of health facilities is also demonstrated by the influence of non-structural damage affecting critical equipment and installations on the overall performance.
The continuous monitoring of the dynamic response leads also to a characterization of the influence of environmental factors on the structural response.

As a conclusion, RBD palm olein has better performance properties in terms of friction reduction (coefficient of friction) and wear resistance (anti-wear properties) at low and high speed.
In this experiment, the constant load 10N and different sliding speeds which are predictable to affect the friction and wear characteristics were considered.
Generally, larger wear scars on the surface it shows that it produce more wear and also another factor such as a lubricant.

Summary Underground mining In the slope outer region, as two kinds of mining influence domain in a partially overlapping, the underground mining disturbance influence the slope stability, making the influence domain of the slope rock mass stress field cause the fundamental change; thus affect the slope stability; If you ignore the influence factors of stress history, the analysis result will be inconsistent with the actual situation; Thus affecting the authenticity of theoretical evaluation, so explore the effect of outer region underground mining on slope stability properties, will have important theory and value in use to the similar mining conditions of slope safety assessment and design.
Influence properties of the slope stability caused by the underground mining of slope outside 2.1 Division attributes of deformation superposition From the deformation characteristics to see, in the comprehensive effect domain of open pit combined underground mining, the slope rock mass is influenced by the factors, such as weathering, groundwater, rock mass rheology and the stress release caused by mining, produces displacement vector direction is ui (chart 1).
That is to say the stability coefficient of the slope is a function of sinking, horizontal movement, horizontal deformation, tilt, curvature, the mechanical parameters of rock mass and the slope angle; compared to open pit mining, increased underground mining in the slope to produce a variety of deformation parameters, in different spatial position of underground mining area overlying rock body, the above deformation parameters is absolutely inconsistent; at the same time, these parameters also depends on the combined effect of multiple factors, such as coal mining method, roof management method, the geotectonic distribution, rock strength and so on; this shows that If the effect of underground mining is ignored or not considered, it is obviously faultiness and unreasonable.
