Two waterborne polyurethane latexes with different tensile strength were employed to modify mortar and the properties of mortar including air entrainment, setting behavior, compressive and flexural strength were investigated. The results show that curing methods, polymer-cement ratio and water-cement ratio have a significant impact on the compressive and flexural strength. The strength of mortar increased under dry curing condition in the range of the polymer-cement ratio from 0.005 to 0.05 (by weight) at water-cement ratio of 0.5. The hydration of the cement containing waterborne polyurethane latexes was not affected and no visible film was found in SEM images.

This paper introduce a new method for extracting internal wave parameters from SAR image. The surface current induced by the internal wave is simulated according to the KDV equation. Then the radar cross section induced by the internal wave can be calculated. The wind speed and pycnocline depth are modified using the dichotomy method step by step which causes the simulation radar cross sections close to those measured from the SAR image. Finally, both the wind speed and pycnocline depth can be obtained. This method is tested on the example of an SAR image. The simulated internal wave signal is consistent with the radar cross sections of SAR images. Their correlation coefficient is up to 90%, which indicates that this method is convergent and applicable.

In this study, three bio-electrokinetic remediation experiments were carried out to study the external delivery of oil-degrading bacteria by electrokinetics and enzyme activities in saturated soil. Results showed that the oil-degrading bacteria could efficiently transport to the saturated oil-contaminated soil by electrophoresis and/or electroosmosis. Bacterial population increased from 6.02-7.75 log (CFU/g) in the control experiment to 8.53-12.83 log (CFU/g) after external bacterial delivery. Under unidirectional operation, the bacterial populations near the electrodes were lower than those in the middle of the soil as a result of unfavorable pH environments. In bidirectional experiment BEK-B, a relatively low bacterial population in the middle of the soil was observed after the experiment. The activities of catalase, polyphenol oxidase, and dehydrogenase have similar trends with bacterial population in the soil, indicating a good relation between the three enzymes and oil biodegradation of oil in soil.
