1Analysis and calculation model of energy consumption and product yields of delayed coking units显示文摘Delayed coking is an important process used to convert heave oils to light products. Energy consumption and fight oil yield are important factors for evaluating the delayed coking process. This paper analyzes the energy consumption and product yields of delayed coking units in China. The average energy consumption shows a decreasing trend in recent years. The energy consumption of different refineries varies greatly, with the average value of the highest energy consumption approximately twice that of the lowest energy consumption. The factors affecting both energy consumption and product yields were analyzed, and correlation models of energy consumption and product yields were established using a quadratic polynomial. The model coefficients were calculated through least square regression of collected industrial data of delayed coking units. Both models showed good calculation accuracy. The average absolute error of the energy consumption model was approximately 85 MJ/t, and that of the product yield model ranged from 1 wt% to 2.3 wt%. The model prediction showed that a large annual processing capacity and high load rate will result in a reduction in energy consumption.Ren Jingdong Meng Xianghai Xu Chunming Song Zhaozheng JiangQingzhe Liu Zhefu 2012Petroleum Science2012,9,1:4
2Effects of boron number per unit volume on the shielding properties of composites made with boron ores from China显示文摘The total macroscopic removal cross sections,deposited energies and the absorbed doses of three new shielding composites loaded with specific boron-rich slag,boron concentrate ore and boron mud of China for 252Cf neutron source were investigated by experimental and Monte Carlo calculation.The results were evaluated by boron mole numbers per unit volume in composites.The half value layers of the composites were calculated and compared with that of Portland concrete,indicating that ascending boron mole numbers per unit volume in the composites can enhance the shielding properties of the composites for 252Cf neutron source.LI Zhefu XUE Xiangxin LIU Sulan LI Yong DUAN Peining 2012Nuclear Science and Techniques2012,23,6:2

11NAD^(+) exhaustion by CD38 upregulation contributes to blood pressuree elevation and vascular damage in hypertension显示文摘Hypertension is characterized by endothelial dysfunction and arterial stiffness,which contribute to the pathogenesis of atherosclerotic cardiovascular diseases.Nicotinamide adenine dinucleotide(NAD^(+))is an indispensable cofactor in all living cells that is involved in fundamental biological processes.However,in hypertensive patients,alterations in NAD^(+)levels and their relation with blood pressure(BP)elevation and vascular damage have not yet been studied.Yumin Qiu Shiyue Xu Xi Chen Xing Wu Zhe Zhou Jianning Zhang Qiang Tu Bing Dong Zhefu Liu Jiang He Xiaoyu Zhang Shuangshuang Liu Chen Su Hui Huang Wenhao Xia Jun Tao 2023Signal Transduction and Targeted Therapy2023,8,10:0
