| 1 | 有机铬对家禽代谢、胴体组成和禽蛋营养成分的影响显示文摘铬是葡萄糖耐受因子(GTF)不可缺少的成分,具有调控动物食欲、维持正常血糖水平和蛋白质摄入的作用,此外,铬还有抗心脏病和糖尿病的作用(Mertz,1993)。GTF的作用是促进胰岛素的生理功能(Mertz等1974)。胰岛素是调节能量、脂肪代谢、蛋白质沉积和胆固醇利用的重要激素。当细胞的胰岛素敏感性下降,细胞利用葡萄糖和氨基酸的能力受到影响。 | 陈勇 Sazzad M.Hossain | 1999 | 国外畜牧学(饲料)1999，，3： | 9 |
| 2 | 超导磁轴承环锭纺纱工艺中纱线路径的数学建模显示文摘在德国研究基金会(DFG)的资助下,成功研发出一种新型无摩擦超导磁轴承(SMB),可替代钢领/钢丝圈系统的加捻,具有能使现有的环锭纺纱工艺生产率翻倍的巨大潜力。该SMB系统已获得专利授权(DE 11 2012 000 596A5),将其安装在一台环锭纺纱测试仪上测试证实,该系统可以工作。集成型高性能SMB加捻元件对动态纱线路径及纺纱工艺有显著的影响,因此纱线的张力分布和气圈的几何形态与传统的纲领/钢丝圈系统有很大的不同。研究旨在就新集成的SMB系统建立动态纱线路径的数学模型,以阐明纺织技术上和物理上的基础原理知识。 | M.Hossain A.Abdkader C.Cherif 雷明 | 2018 | 国际纺织导报2018，46，3： | 0 |
| 3 | Scale-up effect analysis and modeling of liquid-solid circulating fluidized bed risers using multigene genetic programming显示文摘Understanding scale-up effects on the hydrodynamics of a liquid-solid circulating fluidized bed(LSCFB)unit requires both experimental and theoretical analysis.We implement multigene genetic programming(MGGP)to investigate the solid holdup and distribution in three LSCFB systems with different heights.In addition to data obtained here,we also use a portion of data sets of LSCFB systems developed by Zheng(1999)and Liang et al.(1996).Model predictions are in good agreement with the experimental data in both radial and axial directions and at different normalized superficial liquid and solid velocities.The radial profiles of the solid holdup are approximately identical at a fixed average cross-sectional solid holdup for the three LSCFB systems studied.Statistical performance indicators including the mean absolute percentage error(6.19%)and correlation coefficient(0.985)are within an acceptable range.The results suggest that a MGGP modeling approach is suitable for predicting the solid holdup and distribution of a scaled-up LSCFB system. | Shaikh A.Razzak Saddam A.AI-Hammadi Syed M.Rahman Mohammad R.Quddus Mohammad M.Hossain Jesse Zhu | 2020 | Particuology2020，18，5： | 0 |
