Studies on the Preparation of Nano Amorphous and Intermediate Metastable Phase of α-Quartz-Graphite and Their High Pressure Synthesis and Phase Transition
Studies on the Changes of Intermediate Filament-lamina-nuclear Matrix System and Its Relations with c-myc Oncogene Expression in Normal Erythroid and Induced Murine Erythroleukemia(MEL) Cell Differentiation
By cloning the fusion gene to medium vector p~(UC-121), and replacing CaMV35S promoter by LEA protein D-113 gene promoter from cotton, the plant expression vector p~(BI-LEA-O:G121) was constructed.
We calculate the short range part of π~+-π~-, K~+-K~-, K~+-π~-and K~--π~+potentials by using both the conventional quark-antiquark annihilation mechanism and the hybrid medium state model.
The plasmids pBW34-DREB、pSPROK、pBlueks were digested with the restriction enzymes PstI/KpnI、KpnI/EcoRI、PstI/EcoRI respectively, so three fragments were obtained, and then they were ligated with T4 DNA Ligase, thus we got the medium expression vector pBWD-Tnos;
This paper reports the synthesization of the intermediate product CH3CH2C(CH2O - CH2COC1)3 of the possible antipyretic and antitazocine CH3CH2C (CH2O - CH2CO-
OBJECTIVE To study the influence of thiopurine methyltransferase(TPMT) activity on the pharmacokinetics(PK) of 6-mercaptopurine,which is the intermediate metabolite of azathioprine.
The intermediate, transition states and complexes existed in the aza Wittig reaction H 3PNH+H 2CO→H 3PO+H 2CNH have been optimized by means of ab intio calculations at the MP2/6 31G ** level.
Some attempts have been made to develop new methods.2 So in order to explore an alternative method, the key intermediate 4-benzoyloxy cyclohexanone obtained from 1,4-cyclohesanediol by its benzoylation followed by oxidation is used.
However, high (denaturing) concentrations of Me2SnCl2 (more than 9 mM) caused considerable destabilization of DNA associated with the formation of a partially unfolded intermediate at 13.6 mM of Me2SnCl2.
When either a node or a link in a fault-tolerant network fails, the communication from one node to another using this faulty element must be sent via one or more intermediate nodes along a sequence of paths determined by this routing.
However, only two morphological indices, the middle apical bud and the tooth of leaf base, are unstable, which indicates the extensive influence of environmental factors.
Sap flow velocity at the upper position of the trunk is higher than that of the middle and lower position, but cumulative flux is not significantly different among the upper, middle and lower sections.
Results showed that the biomass of fine roots (? 1 mm) in different layers varied in the following descending order: upper layer, middle layer and lower layer, at approximate ratios of 50:30:20.
The objective of this paper is to deal with a kind of fuzzy linear programming problem based on interval-valued fuzzy sets (IVFLP) through the medium of procedure that turns IVFLP into parametric linear programming via the mathematical programming.
The conclusion that the equilibrium is the continuous function of the dilution rate and substrate concentration in medium in a certain range is concluded.
Many food algae and red tide algae were cultivated in the f/2 medium, and the nitric oxide (NO) concentration of the medium and the cell density were determined.
85.19% of Homoptera and 100% of Symphyla were found in the litter layer at the climax succession stage, while 75.61% of Thysanoptera at the intermediate succession stage.
As designers struggle with these interfacing issues, it is natural to consider the intermediate circuits that can be modeled as multi-valued, discrete logic-level circuits.
For the canonical equations of the variational problem for the extremal legs of the intermediate and maximum thrusts, three new classes of analytical solutions were obtained.
