UV-induced grafting is a useful technique for the surface modification of polymers attributing to its low cost of operation without affecting the buck polymer [9].
Polysulfone was selected as the membrane due to its thermal, mechanical and chemical stability.
To examine the electrical property of the membrane, its streaming potential was measured.
There are many factors affecting the interaction between membrane surface and protein, such as surface charge, surface free energy and topological structure, solution environment and protein properties.
However, more work has to be done in order to achieve better properties for a desired permeability and retention.

This technology affects the following factors: - carbon saturation of the carburized layer; - morphology of martensite and the carbon concentration in it; - volume fraction of the redundant carbide phase and its distribution in the cemented layer; - the presence of residual austenite.
All the abovementioned structural factors affect the change of the carburized layer phases in the process of plastic deformation and, consequently, on the fatigue life of gears.
The glow discharge processing allows not only to reduce the endurance duration in some cases and to enhance mechanical properties, but also to achieve the essentially new effects, related to the availability of phase composition and the diffusion layer structure control.
The identical structural condition of steel after the equivalent modes, both gas and ion carburization, provides the identical change of structure and properties during the deformation hardening.
The reduction of carbon concentration in the matrix (with temperature increase) lowers both the density of fastening dislocation points and the degree of their blocking, what should be positively affect the plastic properties of the matrix.

Study on Leaning Sensing Device Based on Kerosene Ferrofluid Hairong Cui Ningbo University of Technology, School of Mechanical Engineering, Ningbo 315016, China hairongcui@sina.com Keywords: Leaning sensing, Ferrofluid, Property Abstract.
Moreover, the physical properties of ferrofluid is affected and controlled by external magnetic field.
It is also found that output voltage is affected by several influencing factors such as the properties of ferrofluid which is a key parameter for viscosity and magnetization, volume of ferrofluid, winding number and diameter of coils, structure of tube and so on.
The properties of kerosene based ferrofluid used as a leaning sensing device should be characterized by high magnetism, good fluidity and proper viscosity.
So how to prepare proper kerosene ferrofluid which has proper magnetic and streaming property is key factor of establishing the experiment of leaning sensing device based ferrofluid.

Human factors included active fault and passive fault, the active fault was human factors leading to the disasters, human error factors leading to disaster caused largely for internal staff especially specific personnel who will directly determine the specific high-way construction quality and safety incidents in the construction, such as specific construction personnel would directly determine highway construction quality and safety accidents, principal include could cause highway construction system occurring construction accidents or engineering quality accident personal unsafe factors and unsafe behavior, according to the survey analysis: 77% people considered that safety awareness was not strong, 54.8% people considered that security system was not in place, 42.1% people considered to be illegal manipulation equipment, we could see the safety factor was the main human factors causing most highway construction accidents, material factor was the material that leaded to the accident conditions
Highway Construction Accident Hazards Specific Factors.
The operator factor analysis was research in highway construction process of human factors on the influence of accident disasters, statistics showed that 88% accidents were caused by unsafe behavior of the people in the process of building construction, but the person's problem was intertwined complex question on many kinds of factors, such as social and political and economic and psychological and ability and so on, so the operator factor analysis should be give adequate attention.
Mechanical equipment factor analysis.
A lot of mechanical equipment was used in the highway construction process, so it was a very important cause of the accident on unsafe condition of machinery equipment, produce mechanical equipment undesirable reasons were mainly machine inherent reliability and service reliability in two aspects, the factors caused the machine malfunction as follows from the view of mechanical equipment inherent reliability, such as the machine structure hardware design and potential defects and low manufacture quality and poor material and the machine left hidden trouble and faulty in transport and storage and installation, it was mainly reason caused malfunction for environmental conditions and used conditions in the use process, the harsh conditions more prone to error action, at the same time, it was important factors for management system irrational about maintenance and maintenance and use standard or process method was undeserved or operating mistakes.

The figure1 shows the two main aspects and factors of influence.
These parameters control certain machining conditions and can cause the phenomena between the process and the product, such as: high temperatures, surface chemical reaction, density of energy, residual stress and surface mechanical or metallurgical properties modification.
Nevertheless this technique also allows the identification of significant factors of a process and their optimal levels.
