A systematic study of the reaction-sintering between ZrSiO_4 and Al_2O_3 has been made through the determination of real density, shrinkage, relative density of specimens as well as XRD and SEM analysis.
the product was obtained under the following conditions:29℃,200r/min and5d fermentation,with some enzymes activity(dry weight ):proteinase3620u/g(dry weight ),cellulase432u/g and saccharifying en-zyme 203u/g,respectively,and the amount of real protein increased by12.1%.
The model of chlorophyll content with reflectance spectroscopy was built in the range of 400-750 nm,and the results show that the correlation coefficient between the estimated values and the real values is 0.898,and relative standard deviation is 13.6%.
The logical-probabilistic calculus is based on the algebra of logic and rules of substitution of logical arguments in functions of the algebra of logic by their truth probabilities, and logical operations by arithmetical operations.
In the first case the meaning of truth (semantics) of judgements is taken into account, whereas in the second case only the structure of judgements (syntax) is considered.
The truth of this hypothesis was verified in our present study on Hsp16.3, one member of sHsps from Mycobacterium tuberculosis, mainly by utilizing chemical cross-linking.
We find presentations for the irreducible crystallographic complex reflection groupsW whose linear part is not the complexification of a real reflection group.
Motivated by the physical concept of special geometry, two mathematical constructions are studied which relate real hypersurfaces to tube domains and complex Lagrangian cones, respectively.
LetG be a connected, simply-connected, real semisimple Lie group andK a maximal compactly embedded subgroup ofG such thatD=G/K is a hermitian symmetric space.
It is shown here that there are proper subsets of ${\cal M}$ that also form a complete set of translation invariants, and these subsets are characterized.
