| 1 | Characterization and separation of pyrite from Abu Tartur black shale显示文摘This work aimed for pyrite separation from Abu Tartur black shale as a source of sulfur to be an added economic value of Abu Tartur area. The considered samples in the present work were collected from a core drilled in Abu Tartur plateau representing the pyrite-rich black shale of the U. Cretaceous age.Sample characterization was carried out using petrographic microscope, XRD, DTA/DTG, C/S and XRF techniques. Clay minerals, silt-sized quartz, calcite, and hematite were the main minerals associating pyrite(5.34%). Liberation behavior of the sample was about 80% below 5 lm.Sample processing was achieved through one-day soaking followed by classification using 1 inch Mozley hydro-cyclone where about 35.5% by weight went to underflow and 64.5% went to overflow.The underflow product was subjected to an advanced gravity separation process using SB-40 Falcon Concentrator through a CCD statistical design prepared by Design-Expert 6.0 software proposed to optimize the separation process through a study for the effects of frequency(Hz) and water pressure(Psi) on both assay and recovery of the sulfur-rich heavy fraction.A heavy concentrate weighed 10.90% with inorganic sulfur content reached 11.37%(21.24% pyrite) with overall recovery(50.01%) was obtained after two cleaning at the optimum conditions. | Ibrahim S.S.

| 15 | 晚期上皮性卵巢癌腹膜播散模式及腹膜切除范围显示文摘根据晚期上皮性卵巢癌(epithelial ovarian cancer,EOC)患者腹膜播散模式和腹膜切除范围的最新研究进展,分析评估肿瘤细胞减灭术(cytoreductive surgery,CRS)中行全壁腹膜切除术(total parietal peritonectomy,TPP)和内脏腹膜广泛切除术的前瞻性研究初步结果。在手术期间看似“正常”的腹膜中,隐匿性疾病的发生率较高,这可能是疾病复发的来源。腹腔热灌注化疗(hyperthermic intraperitoneal chemotherapy,HIPEC)主要作用于微小病灶和手术过程中脱落到腹腔内的游离癌细胞,从而降低复发风险;与单纯CRS相比,HIPEC联合CRS在无进展生存率和总生存率上均显示出优势。彻底根除这种隐匿性疾病的唯一方法为腹膜切除,TPP与内脏腹膜广泛切除术可能是治疗这种隐匿性疾病最有效的策略。TPP的术后并发症可接受,TPP可延长无进展生存率和总生存率,且TPP后铂类耐药复发的发生率远低于既往结果。 | Aditi Bhatt Snita Sinukumar Praveen Kammar Loma Parikh Gaurav Goswami Shweta Thakkar Sakina Shaikh Sanket Mehta 张新静(翻译) 李雁(审校) | 2022 | 中国肿瘤临床2022，49，24： | 0 |
