Stroma from different developmental stages of fetal liver has different effects on human mononuclear fraction of umbilical cord blood during ex vivo co-culture
Fetal liver (FL) has transient and intense hematopoietic activity during gestation. It has been shown that hematopoietic activity in FL begins at embryonic day (E)11, is maximal at E16 and rapidly ceases there...

Removal of Interference Signals Due to Water from in vivo Near-Infrared (NIR) Spectra of Blood Glucose by Region Orthogonal Signal Correction (ROSC)
A novel chemometric method, region orthogonal signal correction (ROSC), is proposed and applied to pretreat near-infrared (NIR) spectra of blood glucose measured in vivo. Water is the most serious interference co...

Comparing chemical fingerprints of herbal medicines using modified window target-testing factor analysis
A “chromatographic fingerprint” of a herbal medicine is essentially its chromatographic spectrum: a characteristic representation of its chemical components, some of which are pharmacologically active. Since a...

Mutant of a Xylanase-producing Strain of Aspergillus niger in Solid State Fermentation by Low Energy Ion Implantation
In order to obtain an industrial strain with higher xylanase production, the original strain of Aspergillus niger was mutated by N+ implantation (10 keV, 1.04 · 1015–2.08 · 1015 ions/cm2), and a mutant P602 wa...

A novel approach for improving the productivity of ubiquinone-10 producing strain by low-energy ion beam irradiation
Agrobacterium tumefaciens ATCC4452 cells were irradiated by nitrogen ion beam, a new mutagen, with energy of 10 keV and fluence ranging from 2.6×1014 ions/cm2 to 6.5×1015 ions/cm2. A similar “saddle shape” surviv...

Influence of the Scorer Parameter Profile on the Wavelength of Trapped Lee Waves
A three-layer theoretical model was established, in which the atmosphere is divided into three layers based on the Scorer parameter l 2, which is large in the middle layer and small in the other two layers. The w...
