Experimental Materials: EL roots with 300 -700 (±50) microns in size and distilled water (solvent) were obtained from Center of Lipids Engineering and Applied Research (CLEAR), Universiti Teknologi Malaysia.
The result shown in Figure 1(d) illustrates the effect of raw material’s particle size on the yield of extraction of EL.
The yield of extraction was observed decreases as the raw material’s particle size increased.

There are some assumptions before analysis[3], all materials satisfy with Hooke’s law; dead-load along span is uniform and is supported by cable only, so when no live load on, cable shape is parabolic curve and girders have no bending stress; girders are uniform cross section straight beam and their vertical curve in all spans are neglected; there are so many hangers that hanger tension can be neglected; tower longitudinal stiffness and axial compression deformation are neglected, and tower transverse stiffness is sufficient to neglect transverse displacement; girder cross section torsion deformation is considered but curling deformation is neglected, i.e. transverse struts are assumed dense and shear stiffness are sufficient; deformation of free vibration is very small compared with that of static balance, so structure stiffness remains constant during vibration.
(17) in which, is girder length and is material density of girder.
(3) Longitudinal free vibration frequency of two-tower and three-span continuous self-anchored suspension bridge is inverse ratio to girder length (namely length of bridge span), evolution of girder material density and is direct ratio to evolution of girder material elastic modulus.

Introduction The ordinary ceramic without white degree requirement is one of the engineering materials with lower cost, longer life, and more stable performance, such as the V-Ti black ceramics[1,2], which meets the strategic plan of energy conservation and emissions provided by the Party Central Committee[3].
No inner heat source inside the system, and good sealing performance, and ignoring air permeability, and the material properties and temperature are independent. 3.

Although the inverse trend of relative change between temperature-drop and viscosity-increase have been clarified, it seems difficult to obtain theoretical equation analytically on the relative change for a wide range of temperature variations and variety of materials.

Phase-field simulation of three-dimensional dendritic growth Changsheng ZHU 1, a, JunWei Wang 2,b 1CAD Center，Lanzhou University of Technology, Lanzhou 730050 2State Key Laboratory of Gansu Advanced Non-ferrous Metal Materials, Lanzhou University of Technology，Lanzhou 730050，China azhucs@lut.cn, bwtj3318@163.com Keywords: Phase-field model, Dendritic growth, Three-dimensional, Numerical simulation Abstract.
Dendrites are the primary component of solidification microstructures in metals, and they are the basic microstructural form for most crystalline materials.
Microstructure formation is at the center of materials science and engineering, and it is the strategic link between materials processing and behavior[2].
Several methods have been explored to solve directly the full time-dependent free boundary problem such as a time-dependent boundary integral formulation, variational algorithms and front tracking method[3]．Since the phase-field models(PFM) had been advanced, they have rapidly become very popular for the simulation of microstructures evolution during solidification process, and it is emerging as a method of choice for simulating interfacial pattern formation phenomena in crystal growth and other materials sciences．

This is a very well-studied special case of diffusion in two-phase material.
On the other hand, as mentioned above, other Monte Carlo studies [15-17] have shown that the MaxwellGarnett Equation does not do so well when the dispersed phase is represented as squares or cubes as might be used as a primitive model for grains surrounded by wide grain boundary regions in nanocrystalline materials.
