DATA SOURCES: A computer-based online search of Medline and Elsevier was undertaken to identify the articles about tissue engineered ACL published between January 1993 and December 2006 with the of "tissue engineering, ACL, scaffold".
Besides, CBM and CBMdisc databases were retrieved by computer for the articles of umbilical cord blood mesenchymal stem cells in bone tissue engineering published between January 1990 and April 2004 with the same key words in Chinese.
Under the condition of 3.2GHz,5.5GHz,9.4GHz testing frequency,vertical polarization and horizontal polarization,the reflection coefficient of quiet zone is less than 45dB,the nonuniformity of transverse field amplitude is ±0.25dB and the nonuniformity of logitudinal field amplitude is under +2dB.
That such a factorization is possible is well-known to algebraists (and expressed by the formulaSL(n;R[z, z-1])=E(n;R[z, z-1])); it is also used in linear systems theory in the electrical engineering community.
Frames have applications in numerous fields of mathematics and engineering.
It is closely related to practical engineering problems.
Biomimetic strengthening polylactide scaffold materials for bone tissue engineering
The biomimetic three-dimensional porous composite can serve as a kind of excellent scaffold material for bone tissue engineering because of its microstructure and properties.
The biomedical ultrasonic engineering(BUE)is a new frontier science wh-ich combined by the ultrasonics,the modern electranic detected technology and thebiomedical science.This paper reviews the fundamental theory researchs and developedcharacteristics in the BUE.
This paper describes what kind of physiological functions does the human being have andhow to test it. It also introduces test instruments in Japan recently used for the testing of function parametersin the human body engineering, so as to bring considerable of the public.
