Because of the development of micro-electro-mechanical system (MEMS) technology and the increasing need for integration, the electrokinetic microfluidics has tended toward the multilayer devices.
But several roadblocks preclude the widely application of them such as the complex fabrication process and friable properties.
By the research of von Smoluchowski and Rice, there are several factors would affect the electroosmotic flow velocity include: solid surface Zeta potential, dissolved fluid medium viscosity, dielectric constant, the electric field strength and so on [20-21].

While the primary purpose of large plastic deformation studies has been to reduce grain size of the material in order to achieve the desired improvement in the mechanical properties by the above said methods, there seems to be some practical limitation in the achievable grain size in bulk engineering components.
These factors significantly affect Eq. (1) and the predicted thickness deviates considerably from the actual thickness.

When executing strategy dynamically, each equipment's variable is picked up from EquipMap to check its type property, in order to ensure whether the equipment needs to be calculated.
All the equipments' variables are scanned to ensure whether the current equipment's value is affected by the active sensor.

These factors, on turn, always tend to a further increase of deformations of the soil body.
The significant region affected can be considered of a width twice the excavation depth.

When designing hydraulic valve, prototype performances test is done on computer with the computational hydrodynamics method .The properties of hydraulic valve and negative phenomena which are derived from internal flow, such as vortex flow, secondary flow, boundary layer separation, wake, noise can be predicted in drawing design stage.
If not, it will affect the blow frequency of electrical-hydraulic hammer
However, in consideration of such factors as the symmetry characteristics of mobile and computing time and the feasibility it can be approximated two-dimensional flow. 4) No the axial velocity component. 0 x y zf f f= = = , xf , yf , zf represent mass unit components along x , y , z axis; 5) Incompressible fluid 6) Flow is steady flow, and velocity does not change with time. 7) Fully developed laminar flow 2.2Basic equations The fluid inside hydraulic valve is incompressible viscous fluid.

The experimental parameters that affect the extraction effi{TTP}-1279 ciency of Pb ions from aqueous samples were evaluated and optimized.
The hard bulk polymer was grounded in a mechanical mortar and wet-sieved to 30 -80 μm particle size.
In order to optimize conditions for obtaining high effi{TTP}-1277 ciency in preconcentration of neodymium ions by the proposed IIP, it is necessary to adjust several factors including nature and volume of eluent, pH, weight of polymer, preconcentration and elution time.
The detection limit was 1.6 µg L−1.These results indicated the suitability of the Pb–DHCB imprinted polymer for selective SPE and determination of Pb2+ in environmental water Table 3 Recovery studies of trace Pb(Ⅱ{TTP}8545 ) determination in various real samples(n=6) Sample Added /[µg L-1] Found /[µg L-1] R.S.D /[%] Recovery /[%] Waste water Huang River water Drinking water 0 60 0 60 0 60 34.8 92.0 12.3 75.9 5.8 68.7 2.83 2.89 3.11 3.96 2.12 3.89 96.9 98.3 104.8 Conclusion The study above indicated that the synthesized Pb2+-IIP had stable chemical properties, firmly rigid configuration, relatively strong templet affinity and quite good selectivity.

Furthermore, plasma treatments were applied to thermoplastics like PP and PVC to evaluate changes in their surface properties [6].
Increasing surface energy is critical for improving adhesion properties, particularly for applications that involve coating or bonding processes [13].
The study evaluates how variations in treatment parameters such as voltage, exposure time, and airflow rate affect the surface properties of both materials.

One of the key factors that affect service life of turbine blades is associated with vibration prevention techniques.
Due to lower number of degrees of freedom, this approach can be advantageously used, for example, for geometric properties optimization because of less time-consuming computation.

The A, D and E samples’ low living cells was because of two factors: First, the higher volume compared with B and C samples making the cells physically damaged while it’s being poured to a microwell plate; Second, the multiple clean-up process can also wash out the living cells, which making Elisa Reader unable to give a good result [11].
The addition of chitosan to alginate hydrogels unquestionably influences with the numer of astrocytes attached to hydrogel surface as well as affects the event of astrocyte colony [2].

Our proposed design is based on the compound eye function such that the mechanical construction of AWARE2 can be made much simpler and the size can be reduced by almost half.
This will affect the validity and effectiveness of the measurement results.
If the crosstalk seriously affects the imaging quality, then we need to redesign the shape distribution of ESCE.
The optical layout of typical secondary optical elements with general amplification factor is shown in the Fig. 2.
This property enables the system to achieve various applications related to 3D scene geometry, such as synthetic aperture, virtual viewpoint rendering, digital refocusing, and depth-map estimation.
