Silica capillary column 1 (0.095 g/mL, 30 m×0.32 mm) and column 2 (0.10 g/mL, 35 m×0.25 mm) using calcium dodecylbenzenesulphonate as stationary phase was prepared by method of dynamic coating with mercury plug ,and the solvent was acetone.
The LEXUS400 car is equipped with the safety bag system which consists of control elements,main air bag and its explosion tube assembly,auxiliary air bag and its explosion tube assembly,left and right safety belt explosion tube,sensor,inspection and maintenance plug etc.
Results: The accuracy of predictive selection of PDA in preoperation examination is 96.8%, the rate of successful guidance by CDU in operation was 100%, 31 cases of embolization of PDA were succeeded in the first time of operation, the rate of success is 100%, 21 cases among them had no sign of postoperation plug exfoliation or recanalization in follow up survey.
The authors improved on Porstmann's PDA embolization technique with half-orbit controllable catheter and plug pressed set,and occlused PDA of children in 4 cases,success in 3, failure in 1. In operation the authors first built a half-orbit of femoral arteria →aorta→PDA→plumonary arteria→right ventricle and then the pressed plug to PDA with controllable catheter set.
Purpose: Color doppler ultrasound (CDU) was used to select the indication, to diminish the possibility of the plug exfoliation and the arterial injnry and to increase the chance of successful embolization in patients with patent ductus arteriosus (PDA).
A very large sample plug was introduced hydrostatically into the capillary (65 cm × 50 μm i.d.; effective length of 35 cm) over 80 s at a height difference of 11 cm.
In this paper, the main factors impacting the plug flow pattern of a clearwell were investigated by integrating pilot-scale, full-scale clearwell tracer testing and computational fluid dynamics (CFD) simulation.
The optimal ratio of d/W is 0.8-1.2 for maintaining better plug flow pattern.
In a plug-flow reactor, the degradation rate was 10.4 nmol min-1 mg-1 cells.
Thrombin production at these sites in turn enhances platelet activation and the subsequent hemostatic plug formation to minimize bleeding.
