Results:The accordance ratio of diagnosis is 98%,the effective ratio of conservation therapy is 95%,the cure ratio of ESWL(extracorporeal shock wave lithotripsy)is 80%, the ureteroscopy cure ratio is 95%,the opening operation cure ratio is 100%.
In order to implementing the opening and interoperability of GIS,OGC present a series of abstract specifications and implementation specifications. WMS(Web Map Service)based on XML is one kind of por- trayal service in the framework of OGC.
A management information system on the internet was designed and developed for college-level experimental center of high school based on the research of experimental teaching and management. The system is to improve the sharing and opening ability for the laboratory.
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.
Phthalides have primarily undergone two ESI CID pathways: side-chain cleavage with losses of alkenes and ring-opening with eliminations of H2O followed by losses of CO.
Compared with lactide ring-opening polycondensation (ROP), the direct melting polycondensation of LA and CL is more practicable and simple.
Transmission Electron Microscopy (TEM) images further verified the formation of MCM-48 with uniform cubic pore channel system having the pore opening diameter of about 25 ?.
The cationic ring-opening copolymerization of AMO with another oxetane-derived monomer, 3-(2-(2-(2-methoxyethylenoxy)ethylenoxy)ethylenoxy)-3'-methyloxetane (MEMO) was conducted in CH2Cl2 solution using BF3 · OEt2/1,4-butanediol as a co-initiator.
