The microalgae did not reactivate when detected at 48 hours and 120 hours, respectively. The contents of chlorophyl-a, chlorophyl-b and chlorophyl-c were decreased by 50%–80%, which is primary reason leading the death of microalgae. The water quality was back to normal level after 120 hours which was no secondary pollution to aquatic organisms and *** results indicated that the D-2 ballast water discharge standard of IMO was satisfied and ·OH is an ideal green medicamen for killing microalgae in the course of conveying ship’s ballast water.

In this paper, we described a new type of ship ballast water treatment system using hydroxyl radical（·OH）.With physical methods of strong electric field ionization discharge at atmospheric pressure, we used O2 in air and sea H2O（gaseous） ionization, dissociation to a number of oxygen active particles（ROS） such as ·OH, O2+, O2ˉ, O3, H2O+, H2O2 and HO2·, ect, in which ·OH is the main active particle. Through the venturi ·OH was injected into ballast water treatment system, forming a high concentration of ·OH solution which was used to kill the harmful micro-organisms in ballast *** paper presented that single-cell algae with the concentration of 1.12×104 cell ml-1and bacteria with the concentration of 1.95×104 cfu ml-1 were treated by the ·OH solution with the concentration of 2.2 ppm. Death rate could reach almost 100%. The micro-organisms did not reactivate at 48 h and 120 h, respectively. After treatment, the concentration of malondialdehyde（MDA） had obviously growth. BOD and COD decreased *** results indicate that high concentration of ·OH solution has a significant effect on killing algae and bacteria. It can be proved by studying Lipid peroxidation. At the meantime, it has no side effects on seawater and will be a promising method for the treatment of ballast water. The results reach the requirements of Regulation D-2 of International Convention for the Control and Management of Ships’ Ballast Water and Sediments completely.

Objective This study aims to explore the clinical applicability and relevance of giycosaminoglycan Chemical Exchange Saturation Transfer （gagCEST） for intervertebral disc. Methods 25 subjects ranging in age from 24 yrs to 74 yrs were enrolled, gagCEST was acquired using a single-slice TSE sequence on a 3T. Saturation used a continuous rectangular RF pulse with B1=0.8 I^T and a fixed duration time =1100 ms. Sagittal image was obtained firstly without saturation pulse, and then saturated images were acquired at 52 offsets ranging from ＋0.i25 to ＋_7 parts per million （ppm）. MR T2 relaxivity map was acquired at the identical location. Six subjects were scanned twice to assess scan-rescan reproducibility. Results GagCEST intraclass correlation coefficient （ICC） of six subjects was 0.759 for nucleus pulposus （NP） and 0.508 for annulus fibrosus （AF）. Bland-Altman plots showed NP had a mean difference of 0.10% （95% limits of agreement： -3.02% to 3.22%）; while that of AF was 0.34% （95% limits of agreement： -2.28% to 2.95%）. For the 25 subjects, gag CEST in NP decreased as disc degeneration increased, with a similar trend to T2 relaxivity. Gag CEST of AF showed a better correlation with disc degeneration than T2 relaxivity. Conclusion GagCEST in NP and AF decreased as disc degeneration increased, while gagCEST in AF showed a better correlation than T2 relaxivity.
