| 1 | Isolation of bacteria from fermented food and grass carp intestine and their efficiencies in improving nutrient value of soybean meal in solid state fermentation显示文摘Background: Soybean meal is an excellent and cost-effective protein source; however, its usage is limited in the piglet due to the presence of anti-nutritional factors and the antigens glycinin and β-conglycinin. The objective of the current study was to screen and select for bacteria that can be efficiently adopted to ferment soybean meal in order to solve this problem.Results: Bacteria were isolated from fermented soy foods and the grass carp intestine, and strains selected for high protease, cellulase and amylase activities. The isolated bacteria were characterized as Bacillus cereus, Bacillus subtilis and Bacilus amyloliquefacien, respectively. Fermentation with food-derived Isolate-2 and fish-derived F-9 increased crude protein content by 5.32% and 8.27%, respectively; improved the amino acid profile by increasing certain essential amino acids, broke down larger soy protein to 35 k Da and under, eliminated antigenicity against glycinin and β-conglycinin, and removed raffinose and stachyose in the soybean meal following a 24-h fermentation.Conclusions: Our results suggest these two B. amyloliquefaciens bacteria can efficiently solid state ferment soybean meal and ultimately produce a more utilizable food source for growing healthy piglets. | Samantha Medeiros Jingjing Xie Paul W.Dyce Hugh Y.Cai Kees De Lange Hongfu Zhang Julang Li | 2018 | Journal of Animal Science and Biotechnology2018，9，3： | 12 |
| 2 | Coupled modeling of tumour angiogenesis, tumour growth,and blood perfusion显示文摘This paper proposes a more realistic mathematical simulation method to investigate the dynamic process of tumour angio-genesis by fully coupling the vessel growth,tumour growth and associated blood perfusion.The tumour growth and angiogenesis are coupled by the chemical microenvironment and the cell-matrix interaction.The haemodynamic calculation is carried out on the new vasculature,and an estimation of vessel collapse is made according to the wall shear stress criterion.The results are consistent with physiological observations,and further confirm the application of the coupled model feedback mechanism.The model is available to examine the interactions between angiogenesis and tumour growth,to study the change in the dynamic process of chemical environment and the vessel remodeling. | Y.Cai,1,2 S.X.Xu,1,a) J.Wu,3 and Q.Long 2,b) 1) Department of Mechanics and Engineering Science,Fudan University,Shanghai 200433,China 2) Brunel Institute for Bioengineering,School of Engineering and Design,Brunel University,Uxbridge,Middlesex,UK 3) School of Naval Architecture,Ocean and Civil Engineering,Shanghai Jiaotong University,Shanghai 200240,China | 2011 | Theoretical & Applied Mechanics Letters2011，1，4： | 8 |

| 4 | Multiple ballistic impacts on 2024-T4 aluminum alloy by spheres:Experiments and modelling显示文摘Multiple ballistic impacts are carried out on a 2024-T4 aluminum alloy by spherical steel projectiles(5-mm diameter)at~400 m s^(-1),to investigate its dynamic deformation and damage.The ballistic impact process is captured with high-speed photography.Postmortem samples are characterized with optical imaging,three-dimensional laser scanning,microhardness testing and electron backscatter diffraction.With increasing number of impacts,crater diameter increases slightly,but crater depth and crater volume increase significantly,and strain accumulation leads to microhardness increase overall.Crater parameters all follow power-law relations with the number of impacts.Twin-like deformation bands and macroscopic deformation twins are produced by impact as a result of spontaneous dislocation self-pinning under high strain rate,large shear deformation.Under multiple impacts,shear strain accumulation in the arc-shaped region of the crater induces deformation twinning when it exceeds a critical value(~1.1-1.6).It is highly possible that the deformation twins are related to deformation bands,since they both share one set of the{111}pole with the initial matrix grain.A finite element method model is optimized to reproduce experimental observations and interpret deformation mechanisms. | J.C.Cheng S.P.Zhao D.Fan H.W.Chai S.J.Ye C.Li S.N.Luo Y.Cai J.Y.Huang | 2021 | Journal of Materials Science & Technology2021，，35： | 2 |

| 9 | 利用Pms波分裂研究青藏高原东南缘地壳各向异性及变形情况显示文摘通过分析青藏高原东南缘新部署的密集地震台阵的接收函数得到了该区域的地壳各向异性。所测量的接收函数Pms波的分裂时间分布在0.02~0.88s,平均分裂时间为0.28s,这远大于近震S波分裂得到的云南地区上地壳(15km以上)累积的分裂时间,表明研究区地壳各向异性主要来自中下地壳(15km以下)。各次级块体内的Pms波的快波偏振方向与主压应力方向基本一致,在一些大型走滑断裂带附近,如小江断裂带、红河断裂带和澜沧江断裂带,快波偏振方向与断裂带走向基本平行。分裂时间在小江断裂带两侧表现出东侧小,西侧大的特征。在块体内部,由于韧性的中下地壳发生差异运动,从而引起物质沿运动方向排列,产生各向异性。小江断裂带、红河断裂带和澜沧江断裂带附近地壳中分布的低速带、高泊松比和高热流表明断裂带下方可能存在部分熔融,因此在这些深的大走滑断裂带下方的各向异性快波方向沿着断裂带走向分布,主要是由于矿物和熔体在断裂带的走滑运动下发生定向排列引起,说明走滑运动控制着断裂带下方地壳的变形模式。对比Pms波与SKS波分裂模式,本文更倾向于认为研究区地壳与上地幔变形解耦。 | Y.Cai J.P.Wu L.H.Fang W.L.Wang S.Yi 蔡妍(译) 房立华(校) | 2018 | 世界地震译丛2018，49，2： | 0 |
| 10 | Dynamic mechanical properties,deformation and damage mechanisms of eutectic high-entropy alloy AlCoCrFeNi_(2.1)under plate impact显示文摘Shock compression and spallation of a eutectic high-entropy alloy(HEA)AlCoCrFeNi_(2.1)with lamellar structure are investigated via plate impact loading with free-surface velocity measurements.The as-cast and postmortem samples are characterized with transmission electron microscopy,electron back-scatter diffraction and scanning electron microscopy.An accurate Hugoniot equation of state is determined.Af-ter shock compression to∼12 GPa,both the L1_(2)and B_(2)phases retain their ordered structures.Dense dislocations in the{111}slip planes,stacking faults and deformation twins are found in the L1_(2)phase,along with fewer dislocations in the{110}slip bands in the B(2)phase.Shock-induced deformation twin-ning within the L1_(2)phase of this HEA is observed as a new deformation mechanism under various load-ing conditions.For spallation,both ductile and brittle damage modes are observed.The micro voids and cracks prefer to nucleate at the phase boundaries chiefly,then in the B(2)phase.Under similar shock stress,the spall strength of AlCoCrFeNi_(2.1)HEA is about 40%higher than those of other reported dual-phase HEAs due to the high stability of its semi-coherent phase boundaries. | S.P.Zhao Z.D.Feng L.X.Li X.J.Zhao L.Lu S.Chen N.B.Zhang Y.Cai S.N.Luo | 2023 | Journal of Materials Science & Technology2023，，3： | 0 |
