1Seroepidemiology of hepatitis C and its risk factors in Khuzestan Province, South-West of Iran:A case-control study显示文摘瞄准:为丙肝感染的传播评估可能的风险因素并且与丙肝感染在病人之中分析流行病学、临床的模式的特征。方法:在一个五年的时期期间,代表性的研究在指的 HCV 积极个人之中被进行阿瓦十 JundiShapour 大学医院(AJSUH ) 和到 2003 年 9 月 1 日的从 1999 年 9 月 1 日的肝炎诊所。控制组由指的第一次供血者组成了地区性的输血组织。连接酶的免疫吸着剂试金和 recombinant 免疫污点试金反肝炎 C 病毒(HCV ) 测试为二个组被执行。积极浆液标本为 HCV RNA 是用聚合酶链反应(PCR ) 的 retest 编辑。风险因素用一张问询表被评估。在感染的题目之中的报导风险因素(“ HCV 积极”) 与从来没暴露的题目的那些相比(“ HCV 否定”) 到 HCV。结果:514 个题目的一个总数为 HCV, 254 是 HCV 积极的被学习, 260 个 HCV 否定的施主包括了控制组。病人的吝啬的年龄是 28.4 (Std 15.22 ) 年。HCV 积极的题目是更可能的具有男性(63% 对 37%) 。输送 132 (52%) ,非静脉内(n-i.v.) 药滥用和 i.v 药滥用 37 (14.5%) ,血液透析 25 (10%) ,在战争和婚外的性欲活动(2.4%) 收到创伤,(3.6%) 纹身被发现是是 HCV 积极的独立风险因素。没有明显的风险因素能在 29 被表明(11.2%) 积极案例。结论:我们输送和 i.v 药滥用和血液透析的历史是重要的数据 indicate 在我们的区域和血屏蔽的那更小心的 pretransfusion 为 HCV 感染冒因素的风险因为 anti-HCV 必须在我们的血库被介绍。在某些生活方式模式的改进,和在这个区域的习俗可能是必要的阻止感染的传播。Eskandar Hajiani Jalal Hashemi Rahim Masjedizadeh Ali Akbar Shayesteh Esmail Idani Tahereh Rajabi 2006World Journal of Gastroenterology2006,12,30:2
2Partial oxidation of methane over SiO2 supported Ni and NiCe catalysts显示文摘Nickel and nickel-ceria catalysts supported on high surface area silica, with 6 wt% Ni and 20 wt% CeO2 were prepared by microwave assisted(co) precipitation method. The catalysts were investigated by XRD,TPR and XPS analyses and they were tested in partial oxidation of methane(CPO). The catalytic reaction was carried out at atmospheric pressure in a temperature range of 400–800℃ with a feed gas mixture containing methane and oxygen in a molecular ratio CH4/O2=2. The Ni catalyst exhibited 60% methane conversion with 60% selectivity to CO already at 500℃. On the contrary, the Ni–Ce catalyst was inert to CPO up to 700℃. Moreover, the former catalyst reproduced its activity at the descending temperatures maintaining a good stability at 600℃, over a reaction time of 80 h, whereas the latter one completely deactivated. Test of CH4 temperature programmed surface reaction(CH4-TPSR) revealed a higher methane activation temperature(> 100℃) for the Ni–Ce catalyst as compared to the Ni one. Noticeable improvement of the ceria containing catalyst occurred when the reaction test started at a temperature higher than the methane decomposition temperature. In this case, the sample achieved the same catalytic behavior of the Ni catalyst. As confirmed by XPS analyses, the distinct electronic state of the supported nickel was responsible for the differences in catalytic behavior.A.Emamdoust V.La Parola G.Pantaleo M.L.Testa S.Farjami Shayesteh A.M.Venezia 2020Journal of Energy Chemistry2020,29,8:2
3ZnO@NiO纳米晶粒吸附去除氰化物的动力学和热力学(英文)显示文摘合成了ZnO、NiO和ZnO@NiO纳米晶粒,采用红外光谱(FTIR)、X射线衍射(XRD)和扫描电镜(SEM)技术对其进行表征。ZnO、NiO和ZnO@NiO的平均颗粒尺寸为32、50和48 nm。对这些纳米晶粒去除氰化物的能力进行了测定。实验结果表明,与ZnO和NiO相比较,ZnO@NiO纳米晶粒去除氰化物的能力更强。ZnO@NiO纳米晶粒对氰化铁的去除能力比对氰化钠的更高。研究了反应时间、溶液pH值(2~12)、纳米晶粒用量(0.02~0.4 g)和氰化物浓度(5~50 mg/L)等参数对氰化物去除效果的影响。在最优条件下:pH<5,纳米晶粒用量0.2 g,反应时间30 min,ZnO@NiO纳米晶粒对20 mg/L氰化物的去除率可达到90%以上。ZnO@NiO纳米晶粒对氰化物的吸附去除动力学影响规律符合Langmuir准二级吸附动力学模型(k2=4.66×10-2,R=0.999)。热力学研究表明,25°C下,反应的标准焓变化为7.87 kJ/mol,自由能变化为-18.62 kJ/mol。纳米晶粒对氰化物的吸附是一个吸热的自发过程。ZnO@NiO纳米晶粒是一种能有效的去除水或废水中氰化物的吸附剂。Mysam PIRMORADI Saeedeh HASHEMIAN Mohammad Reza SHAYESTEH 2017Transactions of Nonferrous Metals Society of China2017,27,6:2
