| 1 | 5-甲基四氢叶酸抗氧化效应强于维生素C(英文)显示文摘在公认的生化抗氧化剂中,目前还未明确地列入5-甲基四氢叶酸.根据5-甲基四氢叶酸的化学结构,它应该具有强氧化性从而能够有效地保护其它维生素的光降解.本文据此研究了5-甲基四氢叶酸的抗氧化效应.选择光敏感维生素核黄素作为光降解剂.使用荧光光谱仪记录和分析了核黄素分别在叶酸和公认的抗氧化剂维生素C作用下的光降解光谱,以此比较分析它们的抗氧化效应.结果发现,当5-甲基四氢叶酸加入时,核黄素光降解明显变慢,而维生素C的作用不如5-甲基四氢叶酸明显.数据显示,5-甲基四氢叶酸具有明显的抗氧化效应,而且其抗氧化效应较维生素C强. | 吕小云 Arnfinn Hykkerud STEINDAL Asta JUZENIENE Johan MOAN | 2009 | 中国生物化学与分子生物学报2009，25，9： | 7 |
| 2 | Comparative numerical and experimental study of two combined wind and wave energy concepts显示文摘With a successful and rapid development of offshore wind industry and increased research activities on wave energy conversion in recent years,there is an interest in investigating the technological and economic feasibility of combining offshore wind turbines(WTs)with wave energy converters(WECs).In the EU FP7 MARINA Platform project,three floating combined concepts,namely the spar torus combination(STC),the semi-submersible flap combination(SFC)and the oscillating water column(OWC)array with a wind turbine,were selected and studied in detail by numerical and experimental methods.This paper summarizes the numerical modeling and analysis of the two concepts:STC and SFC,the model tests at a 1:50 scale under simultaneous wave and wind excitation,as well as the comparison between the numerical and experimental results.Both operational and survival wind and wave conditions were considered.The numerical analysis was based on a time-domain global model using potential flow theory for hydrodynamics and blade element momentum theory(for SFC)or simplified thrust force model(for STC)for aerodynamics.Different techniques for model testing of combined wind and wave concepts were discussed with focus on modeling of wind turbines by disk or redesigned small-scale rotor and modeling of power take-off(PTO)system for wave energy conversion by pneumatic damper or hydraulic rotary damper.In order to reduce the uncertainty due to scaling,the numerical analysis was performed at model scale and both the numerical and experimental results were then up-scaled to full scale for comparison.The comparison shows that the current numerical model can well predict the responses(motions,PTO forces,power production)of the combined concepts for most of the cases.However,the linear hydrodynamic model is not adequate for the STC concept in extreme wave conditions with the torus fixed to the spar at the mean water level for which the wave slamming on the torus occurs and this requires further investigation.Moreover,based on a preliminary comparison of the displacement,the PTO system as well as the wind and wave power production,the STC concept will have a lower cost of energy as compared to the SFC concept.However,the cost of energy of either the STC or the SFC concept is higher than that of a pure floating wind turbine with the same floater. | Zhen Gao Torgeir Moan Ling Wan Constantine Michailides | 2016 | Journal of Ocean Engineering and Science2016，1，1： | 7 |
| 3 | Numerical Study of a Novel Procedure for Installing the Tower and Rotor Nacelle Assembly of Offshore Wind Turbines Based on the Inverted Pendulum Principle显示文摘Current installation costs of offshore wind turbines(OWTs) are high and profit margins in the offshore wind energy sector are low, it is thus necessary to develop installation methods that are more efficient and practical. This paper presents a numerical study(based on a global response analysis of marine operations) of a novel procedure for installing the tower and Rotor Nacelle Assemblies(RNAs) on bottom-fixed foundations of OWTs. The installation procedure is based on the inverted pendulum principle. A cargo barge is used to transport the OWT assembly in a horizontal position to the site, and a medium-size Heavy Lift Vessel(HLV) is then employed to lift and up-end the OWT assembly using a special upending frame. The main advantage of this novel procedure is that the need for a huge HLV(in terms of lifting height and capacity) is eliminated. This novel method requires that the cargo barge is in the leeward side of the HLV(which can be positioned with the best heading) during the entire installation. This is to benefit from shielding effects of the HLV on the motions of the cargo barge, so the foundations need to be installed with a specific heading based on wave direction statistics of the site and a typical installation season. Following a systematic approach based on numerical simulations of actual operations, potential critical installation activities, corresponding critical events, and limiting(response) parameters are identified. In addition, operational limits for some of the limiting parameters are established in terms of allowable limits of sea states. Following a preliminary assessment of these operational limits, the duration of the entire operation, the equipment used, and weather-and water depth-sensitivity, this novel procedure is demonstrated to be viable. | Wilson Guachamin Acero Zhen Gao Torgeir Moan | 2017 | Journal of Marine Science and Application2017，16，3： | 7 |
| 4 | Fuzzy detection for ultrasonic flaw inspectionof highly scattering materials显示文摘Fuzzy logic detection has been applied to the signal enhancement of ultrasonic flaw echoes from the structure noise due to nonflaw related scattering of ultrasound in highly scattering materials. Cross-correlation, phase difference and fractal dimension are used as signal characteristics in fuzzy logic detection. Experimental results show that this new method has better performance than the commonly used correlation detection. | LIU Zhenqing and WEI Moan (Institute of Acocustics, Tongji University Shanghai 200092) | 1997 | Chinese Journal of Acoustics1997，16，4： | 6 |
| 5 | 西藏人体维生素D测量显示文摘为了解西藏自治区当地居民维生素D的状况,并探究影响维生素D含量的可能原因,于2008~2009年连续6次对西藏日喀则尼仓村16名农民(男性7人,女性9人)采集血样,共计81份血样;于2012,2013年两次在西藏拉萨、定日、那曲、日喀则4个地区各选取15~50名居民采集血样,最终获得290份血样。其中126份来源于男性,164份来源于女性。血样经自治区人民医院专业医师处理后提取血清后采用放射免疫法测定血清25(OH)D含量。经分析,西藏地区平均血清25(OH)D含量为12.25 ng/m L。男性的血清25(OH)D含量为(12.8±4.9)ng/m L,女性平均为(11.9±5.3)ng/m L。根据中国老年学学会骨质疏松委员会标准,仅10.4%的男性和4.2%的女性维生素D含量达到足够状态(P<0.05)。青年人的血清25(OH)D水平要高出中老年人20%。夏季的血清25(OH)D水平要高于冬季约30%。不同职业的人群血清25(OH)D水平具有差异,牧民、教师和学生的均高于农民。总之,西藏自治区平均维生素D含量处于不足状态;通过观察发现,这与当地居民的衣着方式、肤色和饮食习惯有很大的关系。另外,不同季节、年龄、性别、地区人体血清25(OH)D含量不一样。其中原因值得我们去反思和探究。 | 措加旺姆 段杰 诺桑 卓玛次仁 Li Wei Ma Johan Moan | 2017 | 药物生物技术2017，24，5： | 3 |
