超重核~(294)118和~(291)116及其α衰变链上各核素半衰期的研究

运用推广的液滴模型(GLDM)确定了超重核294118和291116及其α衰变链上各核素的衰变势垒,采用量子力学中的WKB方法计算α衰变中的势垒穿透几率,对该链上各原子核的α衰变半衰期进行了研究。此外,还利用Royer公式对该链上各原子核的α衰变半衰期进行了计算。结果表明,GLDM考虑亲和能与Royer公式给出的α衰变半衰期与超重核区的实验值符合很好,验证了GLDM和Royer公式在超重核区的适用性,可以用来预测超重核的半衰期。最后,预言了Z=118和116同位素链上各核素的半衰期,结果表明,在Z=118和116中存在α衰变长寿命同位素,这需要实验上的检验。

Brown sediment with well dispersed clasts. Clasts range from small to medium in size and angular to sub-rounded in shape. Some appear to have been weathered. Water escape structures can be seen, mainly in finer, clay rich sediment. Lineations can also be seen throughout the sample. Minor grain stacking and crushing are also present.

Symptomatic intracranial haemorrhage after intra-arterial thrombolysis in acute ischaemic stroke: assessment of 294 patients treated with urokinase

BACKGROUND: The PROACT II trial showed that intra-arterial thrombolysis (IAT) is effective for treatment of acute ischaemic stroke attributable to M1 and M2 segment occlusions. Incidence of symptomatic intracranial haemorrhage (sICH) was 10%. OBJECTIVE: To evaluate the risk and predictors of sICH after IAT by using urokinase in a large number of patients presenting with the whole spectrum of cerebral vessel occlusions. METHODS: 294 patients with stroke treated with intra-arterial urokinase were retrospectively analysed. The risk of sICH as well as bleeding characteristics were assessed. Demographic and radiological data, time to treatment, urokinase dose, recanalisation rates, stroke aetiology and severity were analysed for predictors. RESULTS: sICH occurred in 14 of 294 (4.8%) patients. The median National Institute of Health Stroke Scale score of all patients was 15. All but one sICH were located in the infarcted brain tissue, and no sICH occurred in patients with peripheral vessel occlusions (M3 or M4 segments of the middle cerebral artery). Poor collaterals (p = 0.001), early signs of ischaemia on computed tomography (p = 0.003), higher urokinase dose (p = 0.019), lower recanalisation rate (p = 0.02) and higher diastolic blood pressure on admission (p = 0.04) were found to be correlated with sICH on univariate analysis. On multivariate analysis, poor collaterals (p = 0.004), urokinase dose (p = 0.021) and early signs on computed tomography (p = 0.026) remained predictors of sICH. CONCLUSIONS: With regard to the whole spectrum of cerebral vessel occlusions, an incidence of <5% sICH after IAT is distinctly low. This result underlines the important role of IAT in the treatment of acute stroke.
