Liner services network design and fleet deployment with empty container repositioning

Transportation demand of shipping container fluctuates due to the seasonality of international trade, thus, every 3–6 months, the liner company has to alter its current liner shipping service network, redeploy ships and design cargo routes with the objective of minimizing the total cost. To solve the problem, the paper presents a mixed integer linear program model. The proposed model incorporates several relevant constraints, such as weekly frequency, the transshipment of cargo between two or more service routes, and transport time. Extensive numerical experiments based on realistic date of Asia–Europe–Oceania shipping operations show that the proposed model can solve real-case problems efficiently by CPLEX. The results demonstrate that the model can reduce ship’s capacity consumption and raise ships’ capacity utilization.

巯基棉预浓集—中子活化法测定水泥及其浸出水中的微量汞

在不同酸度下巯基棉可以从溶液中富集和分离Au、As、Ag、Br、Cu、Ca Co、InHg、Ni、Se、Sb、Sn、Pb、W、Fe和In等30多种元素。由于用巯基棉吸附待测元素后不必洗脱,因此大大提高了富集能力,可用于海水、地下水、地表水及工业废水中一些元素的测量。本文用巯基棉富集后进行中子活化分析测定水泥及其浸出水中的汞。

Antimicrobial finishing of regular and modified polyethylene terephthalate fabrics

An effective two-stage method has been developed for imparting antimicrobial properties to regular polyethylene terephthalate (R-PET), polyethylene glycol modified polyethylene terephthalate (PEG-M-PET), R-PET/Cotton blend (R-PET/C) and PEG-M-PET/Cotton blend (PEG-M-PET/C) fabrics. The method consists of partial hydrolysis of the fabrics to create carboxylic groups in PET macromolecules followed by subsequent reaction with dimethylalkylbenzyl ammonium chloride (DMABAC) under alkaline conditions. The reaction conditions such as pH, reaction temperature and time, carboxylic content, and DMABAC concentration were studied. Characterization of the finished fabrics was carried out through scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR). All the modified PET fabrics showed excellent antibacterial activity towards Gram-positive (Bacillus mycoides), Gram-negative (Escherichia coli), and nonfilamentous fungus (Candida albicans). The achieved antimicrobial functions on the PET fabrics are durable in repeated laundering processes. Even after laundering 10 times the fabrics could still provide more than 85% of its antimicrobial activity against B. mycoides, E. coli, and C. albicans. © 2008 Wiley Periodicals, Inc.

多元羧酸与指甲醌染料交联染棉的结构及性能

为了提高天然染料对棉纤维的染色固色性能,以聚马来酸（PMA）和柠檬酸（CA）为交联剂应用于天然染料指甲醌对棉织物的交联染色。采用FTIR、SEM和XRD分析了染色前后棉织物的表面形态及结构,探讨了酯交联对棉织物性能的影响以及多元羧酸复配交联染色机理。结果表明,染色前后棉织物表面差别不大,各纤维间不粘连;直接染色后的棉纤维表面变化不明显,仅有少量染料附着,而交联染色后的棉纤维表面负载较多的染料导致其粗糙度增加,酯化反应主要发生在纤维的非晶态区。与直接染色棉织物相比,交联染色棉织物的染色深度（K/S）和上染率分别提高了88%和38%;染品的绿光、黄光增加,颜色饱和度提高;摩擦色牢度提高了1~2级;耐洗色牢度提高了1~2级;交联染色后棉织物的折皱回复角（WRA）提高了约60%,UPF值达到了50+,具有优异的抗紫外性能。
