补偿收缩砂浆通常为预拌水泥基材料。在众多粉状组成成分中便含有膨胀剂,以死烧氧化钙(CaO)或硫铝酸钙(CSA)为代表的膨胀剂,在钢筋或粗糙混凝土基层摩擦力的限制作用下,在修补砂浆中产生压应力。由于CaO或CSA膨胀剂只有在有水的情况下... 详细信息

补偿收缩砂浆通常为预拌水泥基材料。在众多粉状组成成分中便含有膨胀剂,以死烧氧化钙(CaO)或硫铝酸钙(CSA)为代表的膨胀剂,在钢筋或粗糙混凝土基层摩擦力的限制作用下,在修补砂浆中产生压应力。由于CaO或CSA膨胀剂只有在有水的情况下才能水化,因此为保证使用效果,砂浆必须仔细养护,如不进行仔细的潮湿养护,修补工作很可能由于没有产生有效的压应力而失败,预压应力由限制膨胀产生。本工作致力于研究含CaO或CSA膨胀剂、减缩剂(SRA)砂浆在有无潮湿养护下的性能。由于有减缩剂SRA与膨胀剂的配合,即使在没有任何潮湿养护措施下,也会产生限制膨胀。但是,当CaO与减缩剂SRA复合使用时,这种效应比CSA膨胀剂更明显。

组织多普勒分析是评价舒张功能的一种新型超声心动图检查方式。本文报道对1组15例心肌致密化不全患儿进行组织多普勒分析的结果。二维超声心动图检查显示只有8例患者的收缩功能降低。分析发现有7例患者的舒张功能发生改变:2例患者的全部节段均可见E波降低,3例患者的舒张功能障碍限于尖段和外侧段,其余2例患者的E波降低仅见于尖段。收缩功能障碍和舒张功能障碍之间存在强相关性:事实上,存在舒张功能障碍的所有患者亦表现出收缩功能的显著降低。

We present u＇g＇R optical images taken with the MMT/Megacam and the Subaru/Suprime telescopes of the Extended groth Strip survey. The total survey covers an area of about -1 degree2, including four sub-fields and is optimized for the study of galaxies at z - 3. Our methods for photometric calibration in AB magnitudes, the limiting magnitude and the galaxy number count are described. A sample of 1642 photometrically selected candidate Lyman-Break galaxies （LBgs） to an apparent RAB magnitude limit of 25.0 is presented. The average sky surface density of our LBg sample is -1.0 arcmin-2, slightly higher than the previous finding.

AIM: To asses the value of computed tomography (CT)-perfusion in the detection of residual hepatocellular carcinoma (HCC) vascularization after transarterial chemoembolization (TACE). METHODS: Thirty-two consecutive patients were pro-spectively included in this study. All patients had liver cirrhosis and a conf irmed HCC lesion which was treated with TACE. One month after treatment, perfusion measurements of treated lesions were carried out. The CTperfusion (CT-p) protocol was performed with 16 slice multidetector computed tomography which included the following parameters: 8 dynamic slices/scan per 40 scans after iv injection of 50 mL of iodinated contrast (350 mg/mL) at a flow rate of 6 mL/s. Treated lesions were evaluated using dedicated perfusion software, which generated a quantitative colour map of perfusion. The following parameters were considered: hepatic perfusion (HP), arterial perfusion (AP), blood volume (BV), hepatic perfusion index (HPI), and time to peak (TTP). Perfusion parameters were described with quartile values of their distribution and statistically analyzed. RESULTS: Perfusion parameters of the treated lesions could be quantitatively assessed using CT-p analysis. The presence of residual tumor tissue was observed in 13 of the 32 patients. The values of the perfusion parameters measured within the relapse tissue were: HP (mL/100 g per minute): median = 44.4 (1stqt = 31.3, 3rdqt = 55.8); BV (mL/100 g): median = 18.7 (1stqt = 11.5, 3rdqt = 22.5); AP (mL/min): median = 39.0 (1stqt = 36.5, 3rdqt = 61.3); HPI (%): median = 34.0 (1stqt = 30.4, 3rdqt = 38.9); TTP (s): median = 17.3 (1stqt = 15.8, 3rdqt = 26.5). With the use of the univariate paired Wilcoxon signed rank test, HP, AP and HPI were shown to be significantly higher (Pgreater and lower, respectively, in the relapse site than in the primary lesion. CONCLUSION: In patients with HCC treat

Objective: To determine if supracostal renal access above the 11th rib during percutaneous nephrolithotomy (PCNL) is a safe option in carefully selected patients determined by preoperative computed tomography (CT) imaging. Patients and Methods: We retrospectively isolated 142 patients who underwent access above the eleventh rib during PCNL, which we term “high supracostal renal access.” We then compared these patients to 113 individuals who underwent access below the twelfth rib. Renal access was achieved by the operative surgeon with fluoroscopic guidance in conjunction with pre-operative computed tomography (CT) scan. Outcomes were compared. Results: Overall surgical outcomes were equivalent when comparing high supracostal versus subcostal access sites. As expected due to proximity, pleural complications occurred in 4% of the high supracostal group (n = 6) compared with 0% of the control (subcostal) group (p = 0.035). Of these six complications, three were managed conservatively with observation and two required cardio-thoracic intervention with video-assisted thoracoscopic pleural repair (1%). In the remaining case, the patient was preoperatively consented for placement of a thoracostomy tube, which was placed during the procedure, due to the difficult location of her upper pole stone and closely adjacent low-lying pleura, and the planned transpleural approach. Hospital stay was not significantly pro-longed between the high supracostal access and subcostal access groups, with an average length of stay of 2.2 ± 2.1 days and 2.0 ± 1.9 days (p = 0.59) respectively. Conclusions: Careful, systematic preoperative planning based on CT and fluoroscopic imaging allows for a confident understanding of a “safety zone” in placement and dilatation of renal access points during PCNL. We have shown that planned upper pole renal access above the 11th rib is achievable with acceptable morbidity and excellent success rates.
