开展钢渣碳酸化硬化为结构材料的研究,具有利用废渣和CO废气的双重意义。本文相继对Φ26×30mm圆柱体坯体以及190mm×90mm×88mm六孔空心砖坯进行了碳酸化硬化研究。测定了不同细度、碳化反应时间对碳化硬化试块固结CO量、空隙率、体积变化及力学强度的影响,利用XRD分析了产物的类别,利用SEM观察了硬化产物的显微形貌、生长位置及碳化深度,采用压蒸法测定试块的安定性进行了测试。结果表明了六孔空心砖坯在固结CO的同时,能产生很好的力学强度,且多孔砖抗冻性能优良,此外,压蒸安定性试验表明了钢渣碳酸化硬化试块体积安定性良好。结果还表明,钢渣中CS、CS、Ca(OH)、f-CaO、MgO是易被碳化的矿物,而Ca(Al,Fe)O、FeO矿物难以被碳化。

Introduction: Nowadays the more accepted surgical option for treating early breast cancer is breast conserving surgery. The main challenge in this type of surgery is to get free safety margins without need of second surgical operation, so many breast surgeons have started to depend on intraoperative frozen sections to ensure free safety margins. Aim of work: To assess our policy that we prefer to depend on intraoperative frozen section analysis to get free safety margin in breast conserving surgery from the 1st surgery, and its oncologic outcome. Patients and Methods: This is a retrospective study conducted in Oncology Center—Mansoura University (OCMU), where the data of 219 patients with breast cancer, who were managed by breast conserving surgery with intraoperative frozen section analysis of the safety margins, was analyzed. Results: The intraoperative frozen section analysis of safety margin was negative from the start in 183 (83.6%) patients, while it was positive in 36 patients (16.4%). Intraoperative decision of margin re-excision was applied for 29 patients (13.2%) in order to reach negative margin, modified radical mastectomy was offered for 4 patients (1.8%), while nipple sparing mastectomy with immediate breast reconstruction using latissimus dorsi flap was offered for 3 patients (1.4%). The postoperative paraffin results were typical with intraoperative frozen section analysis results in 216 patients (98.6%) and different results were obtained in only 3 patients (1.4%) who were managed by modified radical mastectomy in a second operation. Only 4 patients had local recurrence (1.8%) during the period of follow-up duration which was ranged from 1 to 86 months with mean ± SD (22.3 ± 14.1). Conclusion: The intraoperative frozen section analysis of safety margins in breast conserving surgery has very high-rate typical results with the paraffin section analysis and it is very helpful in decreasing the rate of second surgical operation in cases of infiltrated m

从理论和试验的角度,分析玻璃纤维加固的纤维复合(FRP)钢管混凝土梁(RCFFT)的抗弯强度和性能。共进行10根梁的四等分点加载试验。细丝状环绕的玻璃FRP钢管被用于试验梁的结构模板。其中,6根梁采用玻璃FRP筋加固,而另4根采用一般钢筋加固。试验参数为FRP钢管管壁厚度、混凝土抗压强度、钢管内部加固材料(钢或FRP筋)的类别和横向加固材料(螺旋钢或FRP钢管)的类别。基于实际测量的荷载、变形和应力值,讨论了梁的屈服强度、极限强度、失效模式和延性。结果显示,FRP钢管梁的延性和强度有所提高。提出一种从线弹性分析理论派生的简化方法,可用于预测RCFFT梁在破坏模式下的屈服弯矩和抵抗弯矩。另外,提出开裂弯矩求解的改进方程,用于说明FRP钢管作为约束结构产生的效应。

There is evidence that a substantial part of genetic predisposition to prostate cancer （PCa） may be due to lower penetrance genes which are found by genome-wide association studies. We have recently conducted such a study and seven new regions of the genome linked to PCa risk have been identified. Three of these loci contain candidate susceptibility genes： MSMB, LMTK2 and KLK2/3. The MSMB and KLK2/3 genes may be useful for PCa screening, and the LMTK2 gene might provide a potential therapeutic target. Together with results from other groups, there are now 23 germline genetic variants which have been reported. These results have the potential to be developed into a genetic test. However, we consider that marketing of tests to the public is premature, as PCa risk can not be evaluated fully at this stage and the appropriate screening protocols need to be developed. Follow-up validation studies, as well as studies to explore the psychological implications of genetic profile testing, will be vital prior to roll out into healthcare.
