Venous enhancement at the level of collum femoris was taken. The measurements were obtained at 10 sec intervals for 310 sec. The parameters of CT scan were as follows: contrast dose corresponds to 1.5 ml/kg,flow rate 3.0 ml/s,injection from antecubital vein,the range of scan time 70～380 s.
Methods 38 cases clinically suspected of arteriosclerotic occlusive disease of lower extremities underwent CT angiography using a 16-slice scanner with range from abdominal aortic -renal arterial level to ankle joint, slice increment 2.5mm, pitch 1.375:1, reconstruction increment 1.25mm.
The maximum scope of GBA presented at the level of the sagital part of the left portal vein with mean right to left distance of (4.39± 0.08 )cm (3.8～5.7 cm) (distance between the left and right layer of the gastrophrenic ligament).
Spectral radius properties for layer potentials associated with the elastostatics and hydrostatics equations in nonsmooth domain
By producing a L2 convergent Neumann series, we prove the invertibility of the elastostatics and hydrostatics boundary layer potentials on arbitrary Lipschitz domains with small Lipschitz character and 3D polyhedra with large dihedral angles.
On the Spectra of Elastostatic and Hydrostatic Layer Potentials on Curvilinear Polygons
As supersonic speed at upper reaches and subsonic speed at lower reaches in a duct, the position of shock layer is analyzed and the asymptotic estimation of solution, is obtained.
Using the stretched variable and the method of boundary layer correction, the formal asymptotic expansion of solution is obtained.
Discrete singular convolution method with perfectly matched absorbing layers for the wave scattering by periodic structures
The study showed that the water molecules between the HAP faces were under conditions of strong electrical field and high pressure, and hence formed 2-3 well-organized water layers on the crystal surfaces.
These structured water layers had ice-like features.
Compared with the crystallographic  direction of HAP, the polarity along the  direction was stronger, which resulted in more structured water layers on the surface.
This study revealed the formation and the detailed structure of water layers on HAP surfaces and suggested that the interfacial water played an important role in stabilizing the HAP particles in aqueous solutions.
Mordenite composite membranes were prepared by means of coating a porous α-alumina support with nanosized mordenite seeds followed by hydrothermal crystallization.
Results showed that optically variable pigments can be prepared by coating Cr2O3 on the surface of the pretreated TiO2-coated mica.
Effect of TiO2-coating on structure and electrochemical performance of LiCo0.2Ni0.4Mn0.4O2
LiCo0.2Ni0.4Mn0.4O2, as the cathode material for lithium ion batteries, was modified by TiO2-coating.
The results suggest that a small amount of TiO2-coating does not change the crystalline structure, but considerably improves the electrochemical performance of LiCo0.2Ni0.4Mn0.4O2 in terms of capacity delivery and cyclability.
