Effect of water matrices on removal of veterinary pharmaceuticals by nanofiltration and reverse osmosis membranes

引用

Journal of Environmental Sciences 2011年第8期23卷 1299-1307页

作者： Davor Dolar Ana Vukovi Danijela Aperger kreimir Kouti Department of Physical Chemistry Faculty of Chemical Engineering and Technology Maruliev trg 19 10000 Zagreb Croatia Department of Analytical Chemistry Faculty of Chemical Engineering and Technology Maruliev trg 19 10000 Zagreb Croatia

This study explored the removal of five veterinary pharmaceuticals （VPs）（sulfamethoxazole （SMETOX）, trimethoprim （TMP）, ciprofloxacin （CIPRO）, dexamethasone （DEXA） and febantel （FEBA）） from different water matrices （Milli-Q water, model water, tap water and real pharmaceutical wastewater using four types of nanofiltration （NF） membranes （NF90, NF270, NF and HL） and two reverse osmosis （RO） membranes （LFC-1 and XLE）. All VPs were added to different water matrices at a concentration of 10 mg/L. Rejections of VPs and water flux were measured. The rejection increased with increase of molecular weight. The highest rejections were obtained with RO membranes （LFC-1, XLE） and tight NF （NF90） membrane. In general, the rejection of VPs was higher in model water and tap water than in Milli-Q water, but the water flux was lower. This was mainly explained by ion adsorption inside the membranes pores. Narrower pore size counteracted the effect of presence of low concentration of natural organic matter （NOM） in tap water. The NOM was assumed to enhance the adsorption of VPs onto membrane surface, increased the size exclusion and electrostatic repulsion also appeared during the transport. Investigated water matrices had influence on water flux decline due to their complexity.

The IOSS Chaos Synchronization Method

引用

Chinese Physics Letters 2011年第1期28卷 32-35页

作者： Choon ki Ahn Faculty of the Department of Automotive Engineering Seoul National University of Science&Technology172 Gongneung 2-dongNowon-guSeoul 139-743Korea

A new synchronization method, called the input/output-to-state stable synchronization (IOSSS) method, is proposed for a general class of chaotic systems with external disturbance. By introducing Lyapunov stability theory and linear matrix inequality (LMI) for the first time, the IOSSS controller is shown to not only guarantee the synchronization of the chaotic systems, but also reduce the effect of external disturbance. The proposed IOSSS controller can be obtained by solving the LMI, which can easily be done using standard numerical packages. A numerical example is given to demonstrate the availability of the proposed method.

In?uence of Carbon Equivalent Value on the Weld Bead Bending Properties of High-Strength Low-Alloy Steel Plates

引用

Journal of Materials Science & Technology 2017年第4期33卷 321-329页

作者： ki Hyuk kim In Jun Moon ki Won kim ki Bong Kang Byung Gyu Park Kwang Seok Lee R&D Center of Dongkuk Steel Mill Co. Ltd Pohang 790-729 South Korea Korea Institute of Materials Science Implementation Research Division Materials Deformation Department 797 Changwondaero Changwon Gyeongnarn642-831 South Korea

The contribution of chemical compositions in terms of carbon equivalent value（CEV） on impending crack propagation during weld bead bend tests（WBBTs） was studied with five different high-strength lowalloy steel plates that underwent different rolling processes. The test showed that cracks developed at the weld joint, easily passed through the coarse-grain heat-affected zone（CGHAZ）, and finally were arrested within the heat-affected zone（HAZ）. An apparent decrease in the average crack length, which consequently indicated improvement in crack arrestability, was found with decreasing CEV. In addition,the relatively fine microstructure in the HAZ of low-CEV steel plates helped in preventing the crack from further propagation. Special emphasis was placed on the empirical expectation of critical CEV above which WBBT might fail.
