1Growth performance and physiological parameters of the second generation selected and control groups of Pinctada martensii显示文摘In May of 2007,the second generation selected (SS) and control (SC) groups of pearl oyster Pinctada martensii were established by selecting 10% breeders with the largest and mean shell length,respectively,from the first generation selected group.Growth performance of the SS and SC groups were compared on the basis of measurement data at Days 8,18,60,95,195 and 365.On Day 365,100 individuals (60.0–75.0 mm at shell length) were sampled from each group and then subjected to the experiment where physiological parameters such as filtrate rate,oxygen consumption and ammonia excretion were measured at 15,20,25 and 30°C.The results show that the SS group had significantly larger mean shell length and shell height than the SC group at Days 8,18,60,95,195 and 365 (P <0.05).The genetic gains at different ages varied from 6.0% to 17.0% for shell length and 5.7% to 14.6% for shell height,respectively.At 15,20,25 and 30 ° C,the SS groups had significantly larger filtrate rate than the SC group (P <0.05).At 15 and 25 °C,the differences in oxygen consumption rate between the SS and SC groups were not significant (P >0.05).At 20 and 30 °C,however,the oxygen consumption rate of the SS group was significantly larger than the SC group (P <0.05).At 15,20,25 and 30 °C,there were no significant differences in ammonia excretion rate between the SS and SC groups (P >0.05).The present results indicate that there existed considerable genetic variability in the base population and a further selection could be likely fruitful.Mass selection for faster growth might produce animals that had higher intake of metabolizable energy by virtue of faster filtrating behavior.DENG Yuewen YU Ziniu DU Xiaodong WANG Qingheng FU Shao 2011Acta Oceanologica Sinica2011,30,2:10
2An Improved LU-SGS Implicit Scheme for High Reynolds Number Flow Computations on Hybrid Unstructured Mesh显示文摘降低上面的对称的 Gauss-Seidel (LU-SGS ) 因为它在格子拓扑学,低数字复杂性和谦虚记忆上有更少的相关性的优点,含蓄的松驰广泛地被使用了要求。在原来的 LU-SGS 计划,含蓄的系统矩阵基于切开对流流动 Jacobian 根据被构造它的光谱半径。尽管这个处理有减少计算复杂性和帮助保证含蓄的系统矩阵的斜主导的性质的优点,因为如果 contravariant 速度对声音的速度小或靠近,太多近似被这个切开的方法介绍,它能也在含蓄的系统矩阵上引起严肃的失真。克服这个缺点,有为含蓄的系统矩阵的一个混合构造方法的一个改进 LU-SGS 计划在这份报纸被开发。混合方法是那:在有小 contravariant 速度或接近音速的 contravariant 速度的房间脸上,对流流动术语的精确衍生物被用来构造更多的精确含蓄的系统矩阵,当切开方法的原来的 Jacobian 在另外的房间脸上被采用减少计算复杂性并且保证含蓄的系统矩阵的斜主导的性质时。为了调查改进 LU-SGS 计划, 2D 和 3D 的集中表演,在 NACA0012 机翼, RAE2822 机翼和 LANN 翅膀附近的狂暴的流动在混合未组织的网孔上被模仿。数字结果证明改进 LU-SGS 计划是显著地,比原来的 LU-SGS 有效的更多策划。WANG Gang JIANG Yuewen YE Zhengyin 2012Chinese Journal of Aeronautics2012,25,1:9
3Characteristics of petroleum accumulation in syncline of the Songliao basin and discussion on its accumulation mechanism显示文摘The relation between oil and water in reservoirs with low and ultra-low permeability is very complicated. Gravitational separation of oil and water is not obvious. Normal reservoirs are located in depression and structural high spot, oil and water transitions are located in their middle. Stagnation is the key fact of oil-forming reservoir in the axis of a syncline based on the research of oil, gas and water migration manner, dynamics and non-Darcy flow in the Songliao basin. In low and ultra-low permeable reservoir, gas and water migrate easily through pore throats because their molecules are generally smaller than the pore throats; but the minimum diameter of oil droplets is larger than pore throats and they must be deformed to go through. Thus, gas and water migrate in advance of oil, and oil droplets remain behind. Pressure differential and the buoyancy force in a syncline reservoir are a main fluid driving force; and capillary force is the main resistance to flow. When the dynamics force is less than resistance, oil is immobile. When the buoyancy force is less than the capillary force, a gravitational separation of oil and water does not occur. The reservoir in the mature source rock of a syncline area with the low and ul- tra-low permeability belongs to an unconventional petroleum reservoir.WU HeYong LIANG XiaoDong XIANG CaiFu WANG YueWen 2007Science China Earth Sciences2007,50,5:9

5Effects of Morphological Traits on Total Weight of Clam Meretrix lamarchii显示文摘Clam Meretrix lamarchii is delicious seafood with high economic value. The M. lamarchii in present market is mainly collected from wild population due to the lack of large-scale artificial seed production. In 2013,we carried out the artificial seedling exploration of M. Lamarchii. The current study utilized several statistical methods to analyze the effects of morphological traits on M. Lamarchii,which may provide knowledge for clam quality seedlings breeding work. The samples of M. Lamarchii were randomly sampled from Donghai Island,Zhanjiang. Shell length( SL),shell width( SW),shell height( SH),ligament length( Li L),lunule length( Lu L) and total weight( TW) of two-year-old M. Lamarchii were measured. A correlation coefficient matrix was constructed based on the results,where the total weight was set as the dependent variable and others as independent variables. Path coefficient and correlation index were calculated,and the major phenotypic characters were determined. The results showed that all the correlation coefficients between independent variables and dependent variable were significant( P < 0. 01),with an exception of the lunule length( P > 0. 05). The effects of the shell length,shell width,and shell height on the total weight were significant( P < 0. 01),and the shell length had dominant effect on the weight as a key effective factor. The multiple regression equation between the weight and the other traits was established as Y_W=- 126. 784 + 1. 249X_(SL)+ 2. 036X_(SW)+ 0. 911 X_(SH),where YWis total weight,X_(SL),X_(SW)and X_(SH)are the shell length,shell width and shell height,respectively. The current study may contribute to the artificial breeding of the species.Zhang Jiali Wang Qingheng Deng Yuewen Du Xiaodong 2015Animal Husbandry and Feed Science2015,7,6:2

7Steam reforming of acetic acid over Ni-Ba/Al2O3 catalysts:Impacts of barium addition on coking behaviors and formation of reaction intermediates显示文摘The influence of barium addition to a Ni/Al2O3 catalyst on the reaction intermediates formed,the activity,resistance of the catalyst to coking,and properties of the coke formed after acetic acid steam reforming were investigated in this study.The results showed the drastic effects of barium addition on the physicochemical properties and performances of the catalyst.The solid-phase reaction between alumina and BaO formed BaAl2O4,which re-constructed the alumina structure,resulting in a decrease in the specific surface area and an increase in the resistance of metallic Ni to sintering.The addition of barium was also beneficial for enhancing the catalytic activity,resulting from the changed catalytic reaction network.The in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) study of the acetic acid steam reforming indicated that barium could effectively suppress the accumulation of the reaction intermediates of carbonyl,formate,and C=C functional groups on the catalyst surface,attributed to its relatively high ability to cause the gasification of these species.In addition,coking was considerably more significant over the Ba-Ni/Al2O3 catalyst.Moreover,the Ba-Ni/Al2O3 catalyst was more stable than the Ni/Al2O3catalyst,owing to the distinct forms of coke formed (carbon nanotube form over the Ba-Ni/Al2O3 catalyst,and the amorphous form over the Ni/Al2O3 catalyst).Zhanming Zhang Yiran Wang Kai Sun Yuewen Shao Lijun Zhang Shu Zhang Xiao Zhang Qing Liu Zhenhua Chen Xun Hu 2020Journal of Energy Chemistry2020,29,4:2
8Direct conversion of furfural to levulinic acid/ester in dimethoxymethane:Understanding the mechanism for polymerization显示文摘This study investigated the conversion of furfural to 5-hydroxymethylfurfural(HMF)and further to levulinic acid/ester in dimethoxymethane under acidic conditions,with the particular focus on understanding the mechanism for polymer formation.The results showed that furfural could react with dimethoxymethane via electrophilic substitution reaction to form HMF or the ether/acetal of HMF,which were further converted to levulinic acid and methyl levulinate.The polymerization of furfural and the cross-polymerization between dimethoxymethane and the levulinic acid/ester produced were the main side reactions leading to the decreased yields of levulinic acid/ester.Comparing to the other solvent,methanol as the co-solvent helped to alleviate but not totally inhibited the occurrences of the polymerization,as the polymerization reactions via aldol condensation did not eliminate the C=O functionalities.As a consequence,the polymerization reactions continued to proceed.Other co-solvent used such as guaiacol,dimethyl sulfoxide and acetone interfered with the transformation of furfural to HMF or aided the polymerization reactions.The polymer produced from the reactions between furfural and DMM was different from that produced from levulinic acid/ester.The former had a higher crystallinity,while the latter was more aliphatic.The DRIFTS and TG-MS studies showed that the polymer had the carboxylic group,methyl group and the aliphatic structure in the skeleton.The removal of these functionalities was accompanied by the aromatization of the polymer.The condensation of DMM with levulinic acid/ester was the key reason for the diminished production of levulinic acid/ester.Yuewen Shao Xun Hu Zhanming Zhang Kai Sun Guanggang Gao Tao Wei Shu Zhang Song Hu Jun Xiang Yi Wang 2019Green Energy & Environment2019,4,4:2

14Reconstructing avascular necrotic femoral head through a bioactiveβ-TCP system:From design to application显示文摘A variety of techniques have been used for treating avascular necrosis of the femoral head(ANFH),but have frequently failed.In this study,we proposed aβ-TCP system for the treatment of ANFH by boosting revascularization and bone regeneration.The angio-conductive properties and concurrent osteogenesis of the highly interconnected porousβ-TCP scaffold were revealed and quantified through an in vivo model that simulated the ischemic environment of ANFH.Mechanical test and finite element analysis showed that the mechanical loss caused by tissue necrosis and surgery was immediately partially compensated after implantation,and the strength of the operated femoral head was adaptively increased and eventually returned to normal bone,along with continuous material degradation and bone regeneration.For translational application,we further conducted a multi-center open-label clinical trial to assess the efficacy of theβ-TCP system in treating ANFH.Two hundred fourteen patients with 246 hips were enrolled for evaluation,and 82.1%of the operated hips survived at a 42.79-month median follow-up.The imaging results,hip function,and pain scores were dramatically improved compared to preoperative levels.ARCO stage II disease outperformed stage III in terms of clinical effectiveness.Thus,bio-adaptive reconstruction using theβ-TCP system is a promising hip-preserving strategy for the treatment of ANFH.Yajie Lu Xiantao Chen Xiao Lu Changning Sun Minghui Li Guojing Chen Zuoyao Long Yuan Gao Haoqiang Zhang Mengquan Huang Chuanlei Ji Hongbin Fan Dong Liu Yuewen Hao Hong Wang Leilei Zhang Hongmei Zhang Jianxi Lu Zhen Wang Jing Li 2023Bioactive Materials2023,,10:1
