饮用水的管理和分配对于大城市的可持续发展至关重要,为了获得对染料优异的吸附能力,优化了在三个pH值下分级海绵状乙二胺四乙酸(EDTA)封装氧化镁(MgO)的吸附条件,并探索了阴离子和阳离子染料模型的吸附性能,即甲基橙(MO)和亚甲蓝(MB)。随着Mg/EDTA补料比例的升高,平均孔径和分数孔隙率下降;FT-IR、SEM、XRD和BET用于表征样品;对于所有MgO样品,吸附过程遵循伪二级动力学模型和MO和MB的Langmuir等温线。在测试样品中,MgO-EDTA(1:1)在浓度为500 ppm和200 ppm时,对MO的吸附量最大,为4131.1mg/g,对MB的吸附量为39.23 mg/g。该研究制备了一种成本低、操作简单的双功能材料,可用于多种行业的有色水修复。毋庸置疑,所描述的方法有效地促进了多孔MgO微球吸附材料的广泛实际应用和规模化生产。

Double Series Identity and Some Laurent Type Hypergeometric Generating Relations

Journal of Mathematical Research with Applications 2020年第5期40卷 476-486页

作者： Mohammad Idris QURESHI Mahvish ali dilshad AHAMAD Department of Applied Sciences and Humanities Faculty of Engineering and Technology Jamia Millia Islamia (A Central University)

The main aim of this article is to obtain certain Laurent type hypergeometric generating relations. Using a general double series identity, Laurent type generating functions(in terms of Kampéde Fériet double hypergeometric function) are derived. Some known results obtained by the method of Lie groups and Lie algebras, are also modified here as special cases.

Molecular and Serological Detection of Crimean-Congo Hemorrhagic Fever Virus in Sulaimani Province, Iraq

引用

Journal of Biosciences and Medicines 2016年第4期4卷 36-42页

作者： Tariq A. G. Aziz Dlovan J. ali dilshad O. Jaff Department of Microbiology College of Medicine Sulaimani University Sulaymaniyah Iraq Department of Microbiology College of Veterinary Medicine Sulaimani University Sulaymaniyah Iraq Gillings School of Global Public Health University of North Carolina Chapel Hill NC USA

Background: Crimean-Congo hemorrhagic fever virus (CCHFV) is a member of the Nairovirus genus in the Bunyaviridae family and is transmitted by ticks of the Hyalomma genus. It causes severe disease in humans with mortality rates between 3% and 30%. The first case in Iraq was reported in 1979;immediately thereafter, 10 cases were reported, resulting in seven deaths. Several cases were also reported in 1980 in Halabja city in Iraq’s Sulaimani province. Methods: Blood samples were collected from two study populations, human and cattle, including butchers working at a slaughterhouse. Ticks were also collected for virus detection from three villages in the Sharazoor district of Sulaimani province. Results: Results of the Reverse Transcription-Polymerase Chain Reaction (RT-PCR) were negative for all human and cattle sera. The tissue prepared from ticks also was negative for CCHFV. An Enzyme-Linked Immunosorbent Assay (ELISA) technique showed that 30 (46.87%) of 64 human sera were positive for the anti-CCHFV IgG antibody. Conclusion: Results show that symptomatic Crimean-Congo hemorrhagic fever (CCHF) is an uncommon disease in the Sulaimani province of Iraq and no clinical cases is reported, due to the eradication of ticks implemented by veterinary authorities. However, other preventive approaches and strategies should be implemented and monitored regularly by local authorities.
