1A new oofamily of dinosaur egg from the Upper Cretaceous of Tiantai Basin,Zhejiang Province,and its mechanism of eggshell formation显示文摘Here we describe new types of dinosaur eggs found from the Late Cretaceous Chichengshan Formation in the Tiantai Basin,Zhejiang Province.On the basis of such characters as small spheroid or near-spheroid,columnar layer composed of three zones,the outer zone consisted of stalagmite-like or coralliform secondary shell units,we established two new oogenera,one new and one combination oospecies:Stalicoolithus shifengensis oogen.et oosp.nov.and Coralloidoolithus shizuiwanensis oogen.et comb.nov.In addition,re-examination of the holotype of Shixingoolithus erbeni from the Upper Cretaceous Pingling Formation,Guangdong Province reveals that it was erroneously attributed to Spheroolithidae,and should be transferred to stalicoolithid.Consequently,we established a new oofamily:Stalicoolithidae oofam.nov.Stalicoolthids represents a new model of dinosaur eggshell and thus sheds new light on the formation and evolution of amniotic eggshells.WANG Qiang WANG XiaoLin ZHAO ZiKui JIANG YanGen 2012Chinese Science Bulletin2012,57,28:6

3Comparisons of Salinity Adaptation in Terms of Growth, Body Composition, and Energy Budget in Juveniles of Rainbow and Steelhead Trouts (Oncorhynchus mykiss)显示文摘This study examined the effect of different salinities(0, 5, 10, 15, 20, 25 and 30) on the growth performance and energy budget of juveniles of two different ecotypes of Oncorhynchus mykiss, landlocked rainbow trout and anadromous steelhead trout. In the 42 d experiment, fish were cultured in three replicate tanks per salinity treatment(eight fish per tank). At the end of the experiment, the growth of rainbow and steelhead trouts was significantly higher at salinities of 5 and 10, respectively, than at all other salinities. The protein, lipid and energy content of both ecotypes declined with the increase of salinity. Based on their energy budgets, the percentage of energy consumed for growth by rainbow and steelhead trouts were significantly higher at salinities of 5(34.00% ±1.69%) and 10(43.76% ± 1.29%), respectively, than at all other salinities. The percentage of energy consumed for respiration by rainbow and steelhead trouts was lower at salinities of 5(54.90% ± 1.77%) and 10(46.73% ± 0.62%), respectively, than at all other salinities. Our results indicated that the salinity adaptation ability of juvenile steelhead trout was slightly better than that of juvenile rainbow trout, and salinities of 10 and 5, respectively, were most suitable for growth of these two fishes.XIONG Yinghuai WANG Xin DONG Shuanglin WANG Fang YANG Jingwen ZHOU Yangen 2019Journal of Ocean University of China2019,18,2:1
4EXPERIMENTAL ANALYSIS FOR SINGULARITIES IN CRACK NORMAL TO BIMATERIAL INTERFACE显示文摘Three kinds of the model of crack normal to the bimaterial interface are studied by anexperimental method.The highly sensitive moire interferometry technique is employed to obtain thedisplacement fields near the crack tip.The singularities of the three kinds of model are determined andanalyzed by the experimental method and compared and discussed.Kang Yilan Wang Shibin Wang Yangen 1998Acta Mechanica Solida Sinica1998,11,2:1
5Production of Pacific White Shrimp Polycultured with Swimming Crab at Different Densities, and Nutrient Budget in the Enclosure System显示文摘This study was to evaluate the effect of stocking densities on the nitrogen and phosphorus budgets for a polyculture of the crab Portunus trituberculatus and the Pacific white shrimp Litopenaeus vannamei.The shrimps(initial weight,0.012 g)were cultured at a density of 45 shrimp m^(-2),and juvenile crabs(initial weight,0.024 g)were cultured at five densities of 0,3,6,9,and 12 crabs m^(-2).The treatments were grouped as C0S45,C3S45,C6S45,C9S45,and C12S45,respectively.Water quality parameters,growth of shrimp and crabs,and nitrogen and phosphorus budget were measured.The results indicated that the shrimp performances in polyculture treatments C3S45 and C6S45 were superior to those in the crab-free treatment(C0S45).The crab in treatments C3S45 and C6S45 exhibited a significantly higher final mean weight and carapace width/length than those in treatments C9S45 and C12S45.The final size and survival of crabs had a negative correlation with the increasing crab stocking density.The contents of total phos-phorus and total nitrogen and the comprehensive contamination index values were higher in the C9S45 and C12S45 treatments than in the other treatments.The conversion ratios of nitrogen for crab and shrimp growth in treatment C3S45 were significantly higher than those in the crab-free treatment.These findings indicate that polyculturing shrimp with crabs at suitable densities can improve productivity,profitability,nutrient utilization,and the environmental quality.From the 60-day treatments,the optimal culture densi-ties were 3-6 crabs m^(-2) and 45 shrimps m^(-2).ZHOU Yangen BAO Weiyang SU Yuepeng HUANG Ming WANG Xingqiang YAN Binlun MA Shen 2022Journal of Ocean University of China2022,21,1:0

7Effect of Temperature on the Carbon, Nitrogen, and Phosphorus Nutrient Budgets of Steelhead Trout (Oncorhynchus mykiss) with Different Sizes显示文摘This study was performed to evaluate the effect of temperature on the carbon(C),nitrogen(N),and phosphorus(P)nu-trient budgets of adult steelhead trout(Oncorhynchus mykiss)with different body sizes.A complete two-factor experiment was con-ducted at four temperatures,i.e.,9(T9),13(T13),16(T1℃℃℃6),and 19(T19);and three body sizes,℃i.e.,0.65 kg±0.02 kg(S1),1.22 kg±0.06 kg(S2),and 2.05 kg±0.09 kg(S3).The following properties of steelhead trout were determined:C,N,and P nutrient budgets;feed intake rate;fecal production rate;oxygen consumption rate;ammonia excretion rate;phosphorus excretion rate;scope of the growth of C,N,and P;and absorption efficiency of C,N,and P.Results showed no significant interaction between temperature and body size in terms of the nutrient budgets of steelhead trout.However,temperature and body size played important separate roles in the nutrient budgets except for the absorption efficiency of nitrogen.The feed intake rate,fecal production rate,ammonia excretion rate,phosphorus excretion rate,and scope of the growth of C,N,and P were the highest in the T16 treatments.The absorption effi-ciency of C and P decreased as temperature increased.Nonlinear multiple regression results indicated that 15 was the approximate℃optimal temperature for the feeding and growth of steelhead trout.The feed intake rate,fecal production rate,oxygen consumption rate,ammonia excretion rate,phosphorus excretion rate,and scope of the growth of C,N,and P per unit of the body weight of fish decreased as body size increased.The absorption efficiency of C increased as body weight increased,and the absorption efficiencies of P in the S2 and S3 treatments were significantly higher than those in the S1 treatment.During the culture of steelhead trout,the daily ratio should be adjusted with changes in the temperature and body size of fish.Furthermore,managers should focus on the risk of hypoxia at high water temperatures.ZHANG Gong GAO Qinfeng ZHOU Yangen DONG Shuanglin WANG Meijun GAO Yonggang 2022Journal of Ocean University of China2022,21,5:0
8Influence of Continuous Withdrawal on Chemistry and Dynamics of Thermal Waters of Mixed Origin:A Case Study in Xinzhou Basin,Fengwei Graben显示文摘Mixing processes are universal in the genesis of thermal waters from Xinzhou basin. Chemical and isotopic (δD-δ18O, 34S/32S, 87Sr/86Sr, T) data are comprehensively used to discern the geochemical and hydrodynamic environments of these waters. Based on a two-year hydrochemical monitoring on thermal waters from the well XD1 in Duncun geothermal field , a series of changes in quality have been observed , which are attributed to the change in the proportion of end members making up the thermal waters being withdrawn.Wang Yanxin Sun Lianfa Luo Zhaohui Wang Yangen Gao Zhao 1995Journal of Earth Science1995,14,2:0
9Facile syntheses of 3-trifluoromethylthio substituted thioflavones and benzothiophenes via the radical cyclization显示文摘3-CF3 S substituted thioflavones and benzothiophenes were achieved via the reactions of AgSCF3 with methylthiolated alkynones and alkynylthioanisoles,respectively,promoted by persulfate.This protocol possesses good functional group tolerance and high yields.Mechanistic studies suggested that a classic two-step radical process was involved,which includes addition of CF3 S radical to triple bond and cyclization with SMe moiety.Lu Wang Huaiyu Wang Weidong Meng Xiu-Hua Xu Yangen Huang 2021Chinese Chemical Letters2021,32,1:0
