| 1 | Significant Effects of Fishing Gear Selectivity on Fish Life History显示文摘Over the past few decades, extreme changes have occurred in the characters of exploited fish populations. The majority of these changes have affected the growth traits of fish life history, which include a smaller size-at-age, an earlier age-at-maturation and among others. Currently, the causes of these life history traits changes still require systematic analyses and empirical studies. The explanations that have been cited are merely expressed in terms of fish phenotypic adaptation. It has been claimed that the original traits of fish can be recovered once the intensity of exploitation of the fish is controlled. Sustained environmental and fishing pressure will change the life history traits of most fish species, so the fish individual's traits are still in small size-at-age and at earlier age-at-maturation in exploited fish populations. In this paper, we expressed our view of points that fishing gear has imposed selectivity on fish populations and individuals as various other environmental factors have done and such changes are unrecoverable. According to the existing tend of exploited fish individual's life history traits, we suggested further researches in this field and provided better methods of fishery management and thereby fishery resources protection than those available early. | LIANG Zhenlin SUN Peng YAN Wei HUANG Liuyi TANG Yanli | 2014 | Journal of Ocean University of China2014，13，3： | 4 |
| 2 | A 2200-year Record of Seabird Population on Ganquan Island,South China Sea显示文摘107 厘米的 Geochemical 特征长沉积侧面,从 Ganquan 岛镇定,华南海,被分析。基于简历元素的集中(Cu, Zn, Cd, Ba,同样 Se, P ) ,标明日期的 210Pb 和 AMS14C,我们重建了在过去的 2200 年的 Ganquan 岛的海鸟人口。海鸟超过 2200 年以前住在这个岛,并且他们的人口分别地在 21001850 年 BP 和 900300 年 BP 附近与二座山峰显示了显著变化。Ganquan 岛上的海鸟人口变化侧面在在过去的 1800 年的 Dongdao 岛上类似于那。我们检验了在海鸟人口和气候之间的关系,并且发现它相当复杂。海鸟人口没与相对高的平均温度在医药温暖的时期(MWP ) 期间到达最大值;然而,它在气候的转变时期和小冰川期(LIA ) 期间在山峰价值附近留下了大约 600 年,显示相对凉爽的气候为 Ganquan 岛上的海鸟是有利的。 | XU Liqiang LIU Xiaodong SUN Liguang YAN Hong LIUYi LUO Yuhan HUANG Jing | 2011 | Acta Geologica Sinica(English Edition)2011，85，4： | 2 |
| 3 | The Tight Sandstone Reservoir in Pyramid Structure,Upper Paleozoic of Erdos Basin显示文摘Pyramid’s Arabic meaning'cone',it is a square bottom spire of stone building in Pyramid,the ancient Egyptian burial tomb of the king and queen are the most typical.Because of its grand scale,its sides are composed of plurality of triangular or triangular surfaces which are connected to the top,the area is very small,even a spire shaped,resembling Chinese characters in'gold'word。 | WEI Xinshan LUO Shunshe SUN Liuyi REN Junfeng ZHAO Huitao LIU Xiaopeng | 2015 | Acta Geologica Sinica(English Edition)2015，89，A01： | 0 |
| 4 | Proteomic characterization of four subtypes of M2 macrophages derived from human THP-1 cells显示文摘Macrophages are widely distributed immune cells that contribute to tissue homeostasis.Human THP-1 cells have been widely used in various macrophage-associated studies,especially those involving pro-inflammatory M1 and anti-inflammatory M2 phenotypes.However,the molecular characterization of four M2 subtypes(M2a,M2b,M2c,and M2d)derived from THP-1has not been fully investigated.In this study,we systematically analyzed the protein expression profiles of human THP-1-derived macrophages(M0,M1,M2a,M2b,M2c,and M2d)using quantitative proteomics approaches.The commonly and specially regulated proteins of the four M2 subtypes and their potential biological functions were further investigated.The results showed that M2a and M2b,and M2c and M2d have very similar protein expression profiles.These data could serve as an important resource for studies of macrophages using THP-1 cells,and provide a reference to distinguish different M2 subtypes in macrophage-associated diseases for subsequent clinical research. | Pengfei LI Chen MA Jing LI Shanshan YOU Liuyi DANG Jingyu WU Zhifang HAO Jun LI Yuan ZHI Lin CHEN Shisheng SUN | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，5： | 0 |
| 5 | Two-Dimensional Numerical Simulation of Flow Around Three-Stranded Rope显示文摘Three-stranded rope is widely used in fishing gear and mooring system. Results of numerical simulation are presented for flow around a three-stranded rope in uniform flow. The simulation was carried out to study the hydrodynamic characteristics of pressure and velocity fields of steady incompressible laminar and turbulent wakes behind a three-stranded rope. A three-cylinder configuration and single circular cylinder configuration are used to model the three-stranded rope in the two-dimensional simulation. The governing equations, Navier-Stokes equations, are solved by using two-dimensional finite volume method. The turbulence flow is simulated using Standard κ-ε model and Shear-Stress Transport κ-ω(SST) model. The drag of the three-cylinder model and single cylinder model is calculated for different Reynolds numbers by using control volume analysis method. The pressure coefficient is also calculated for the turbulent model and laminar model based on the control surface method. From the comparison of the drag coefficient and the pressure of the single cylinder and three-cylinder models, it is found that the drag coefficients of the three-cylinder model are generally 1.3–1.5 times those of the single circular cylinder for different Reynolds numbers. Comparing the numerical results with water tank test data, the results of the three-cylinder model are closer to the experiment results than the single cylinder model results. | WANG Xinxin WAN Rong HUANG Liuyi ZHAO Fenfang SUN Peng | 2016 | Journal of Ocean University of China2016，15，4： | 0 |
