| 1 | 基于MEPDG的温拌发泡沥青混合料性能研究显示文摘为探究泡沫沥青温拌技术对沥青混合料性能及沥青路面设计厚度的影响,通过力学-经验路面设计指南(MEPDG)软件对温拌发泡沥青混合料(WMA Foam)路面和热拌沥青混合料(HMA)路面在相同设计条件下的车辙、疲劳开裂以及国际平整度指标(IRI)等进行预测比较,并根据MEPDG路面设计方法分别得出了温拌发泡沥青混合料和热拌沥青混合料在相同情况下的路面设计厚度。结果表明:采用石灰岩碎石作集料时,WMA Foam与HMA表现出相近的性能。而对以天然砾石为集料的PG 64-22原样沥青混合料,发泡沥青温拌技术的采用使得混合料的车辙深度和国际平整度指数(IRI)相比HMA混合料有显著增加。此外,采用天然砾石和PG 64-22原样沥青的温拌发泡沥青路面设计厚度远大于对应热拌沥青路面的设计厚度。 | 周维祥 Munir Nazzal Ala R.Abbas Ayman W.Ali Arjun Roy | 2016 | 中外公路2016，36，4： | 4 |
| 2 | Validated stability indicating methods for determination of nitazoxanide in presence of its degradation products显示文摘Three sensitive,selective and reproducible stability-indicating methods are presented for determination of nitazoxanide (NTZ),a new anti-protozoal drug,in presence of its degradation products.Method A utilizes the first derivative of ratio spectra spectrophotometry by measurement of the amplitude at 364.4 nm using one of the degradation products as a divisor.Method B is a chemometric-assisted spectrophotometry,where principal component regression (PCR) and partial least squares (PLS) were applied.These two approaches were successfully applied to quantify NTZ in presence of degradation products using the information included in the absorption spectra in the range 260-360 nm.Method C is based on the separation of NTZ from its degradation products followed by densitometric measurement of the bands at 254 nm.The separation was carried out on silica gel 60F 254,using chloroform-methanol-ammonia solution-glacial acetic acid (95:5:1:1 by volume,pH=5.80) as a developing system.These methods are suitable as stability-indicating methods for the determination of NTZ in presence of its degradation products either in bulk powder or in pharmaceutical formulations.Statistical analysis of the results has been carried out revealing high accuracy and good precision. | Nouruddin W.Ali Samah Sayed Abbas Hala El-Sayed Zaazaa Maha Mohamed Abdelrahman Mohamed Abdelkawy | 2012 | Journal of Pharmaceutical Analysis2012，2，2： | 3 |
| 3 | 氮和磷改性的溶胶-凝胶基阻燃化合物显示文摘在德国促进联合工业研究发展计划(IGF)的19617 N号研究项目中,制备了氮和磷取代的烷氧基硅烷,并对其抑制织物火势生长和蔓延的能力进行了研究。为此,采用不同的策略合成了一系列阻燃剂,包括用氨基三烷氧基硅烷和/或三聚氰胺对有机磷化合物进行点击化学和亲核取代。采用轧-烘-焙工艺和溶胶-凝胶法,将新型无卤、无醛阻燃剂应用于棉(CO)、聚对苯二甲酸乙二醇酯(PET)、聚酰胺(PA)及其混纺织物上。阻燃效率通过EN ISO 15025测试方法评估。此外,通过附着在磷原子上的官能团或焙烘温度的优化,可控制阻燃剂的水溶性和耐洗性。总体而言,该项研究表明,N-P-硅烷是良好的纺织品耐久性阻燃剂。 | W.Ali V.Shabani J.S.Gutmann T.Mayer-Gall O.Etemad-Parishanadeh A.Salma T.Textor 何鹏飞(译) 罗艳(校) | 2022 | 国际纺织导报2022，50，2： | 1 |
| 4 | Regular perturbation solution of Couette flow(non-Newtonian)between two parallel porous plates: a numerical analysis with irreversibility显示文摘The unavailability of wasted energy due to the irreversibility in the process is called the entropy generation.An irreversible process is a process in which the entropy of the system is increased.The second law of thermodynamics is used to define whether the given system is reversible or irreversible.Here,our focus is how to reduce the entropy of the system and maximize the capability of the system.There are many methods for maximizing the capacity of heat transport.The constant pressure gradient or motion of the wall can be used to increase the heat transfer rate and minimize the entropy.The objective of this study is to analyze the heat and mass transfer of an Eyring-Powell fluid in a porous channel.For this,we choose two different fluid models,namely,the plane and generalized Couette flows.The flow is generated in the channel due to a pressure gradient or with the moving of the upper lid.The present analysis shows the effects of the fluid parameters on the velocity,the temperature,the entropy generation,and the Bejan number.The nonlinear boundary value problem of the flow problem is solved with the help of the regular perturbation method.To validate the perturbation solution,a numerical solution is also obtained with the help of the built-in command NDSolve of MATHEMATICA 11.0.The velocity profile shows the shear thickening behavior via first-order Eyring-Powell parameters.It is also observed that the profile of the Bejan number has a decreasing trend against the Brinkman number.Whenηi→0(i=1,2,3),the Eyring-Powell fluid is transformed into a Newtonian fluid. | M.NAZEER M.I.KHAN S.KADRY Yuming CHU F.AHMAD W.ALI M.IRFAN M.SHAHEEN | 2021 | Applied Mathematics and Mechanics(English Edition)2021，42，1： | 1 |
| 5 | 吸附用纺织品:从受污染的水中去除PFC的方法显示文摘传统的饮用水和废水处理技术对全氟化碳(PFCs)的去除存在一定的局限性。因此,需要一种先进的全氟化碳去除技术。以聚酯纤维(PET)为基材,采用不同的聚电解质[聚乙烯胺(PVAm)、β-环糊精改性的PVAm和季铵盐改性的PVAm]进行涂层处理,制备了吸附织物,用于去除地下水和工业废水中的PFCs。这种吸附用纺织品是用热轧的方法加工而得的,耐用、性能优良、成本效益可观。PVAm改性的PET对长链全氟碳化合物具有较高的吸附能力,而环糊精或季铵盐类化合物的改性,提高了PET对短链全氟碳化合物的选择性。采用1.5 m 3的中试装置对3种不同来源的受污染地下水进行现场试验。测试结果表明:来自杜塞尔多夫机场附近和在德国一家前纺织整理公司获得的受污染的地下水中的全氟化合物,分别减少了约95%的长链和85%的短链全氟化合物。此外,被短链全氟化碳高度污染的纸质污泥产生的地下水中的PFCs去除率略低。 | A.Salma W.Ali M.Hildenbrandt J.S.Gutmann T.Mayer-Gall C.Kube F.Grüning 杨立双(译) 孟粉叶(校) | 2022 | 国际纺织导报2022，50，5： | 0 |
