On 3rd, 7th, and 14th day, the apoptosis index of spinal cord anterior horn motoneuron in experimental rats were lower(1.2±0.8,1.4±0.6,4.1±1.3) than that in the control group(2.1±1.1,3.1±1.1,6.1±1.8)(P<0.05).
For the lateral meniscus,the height and width of the anterior horn were8.96±2.06mm and4.28±0.70mm,the height and width of the mid-body were9.18±2.12mm and4.74±0.90mm,the height and width of posterior were9.64±2.26mm and5.56±0.86mm,respectively.
② Number of NT3 neurons in ventral and dorsal horns of spinal cord in each group: The number of positive neurons in the ventral horn was significantly greater in 7-day and 21-day cSCI groups than in control and 24-hour cSCI groups (10.2±1.1, 11.4±3.2, 6.2±1.8, 7.4 ±2.4, P < 0.01).
An improved visualization device made of polymethyl methacrylate (PMMA) was used to study the 3D flow profile inside conical columns of a 10° opening angle packed with C18 phase.
The Brill transition of even-even polyamide 618 was investigated using differential scanning calorimetry (DSC), temperature-dependent wide angle X-ray diffraction (WAXD) and Fourier transform infrared (FTIR).
The transmittance passing through the cell between crossed polarizers changed periodically with a regular 90° separation of the rotational angle.
The pretilt angle of the cell was found to be 2.8°.
With the increase of DHPDMS content, the water contact angle increased while the surface tension decreased.
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.
The structure of the pigment was characterized by X-ray diffraction (XRD), and its optically variable effect was investigated by X-Rite MA86 II five angles spectrophotometer.
In NQGA, a novel approach for updating the rotation angles of quantum logic gates and a strategy for enhancing search capability and avoiding premature convergence are adopted.
The 2D/3D scattering center models can be reconstructed based on the wideband measurements at different viewing angles.
Research results show that initiation and propagation laws are the same with interior symmetric wedge angles of 30°-120°, while the laws are different with interior symmetric wedge angles equal to or more than ≥150°.
The modified TEM horn antenna with distributed resistor load is presented in this paper, and the radiation properties of the antenna with the shields and absorbers are studied through the three-dimensional finite-difference time-domain (FDTD) scheme.
Ultrasonic linear motor using the L-B mode Langevin transducer with an exponential horn
An exponential shape horn is adopted to achieve a high linear speed.
The classical theory of the transducer horn is used to determine the transducer's longitudinal resonance frequency and configuration dimensions.
The different locations of the driving tip on the horn cause different elliptical-shaped vibration trajectories, and how the trajectory's shape variation influences motor mechanical output is studied by using the FEM method.
