| 1 | Regulation of protein stability of DNA methyltransferase 1 by post-translational modifications显示文摘DNA methylation 是保证正确基因表示并且维持基因 stability.DNA methyltransferase 的重要 epigenetic 机制(DNMT1 ) 1 是在复制期间维持 DNA methylation 的主要的酶。Dysregulation ofDNMT1 在许多疾病被含有。DNMT1 蛋白质稳定性经由各种各样的 translational 以后修正被调整,例如 acetylation 和 ubiquitination,而且通过 proteinprotein 相互作用。这些机制保证 DNMT1 在房间周期并且在正确 genomic loci 的正确时间期间是 properlyactivated,以及响应适当 extracellularcues。这些规章的机制的进一步的理解可以帮助为人的疾病设计新奇治疗学的途径。 | Anthony Scott Jing Song Rob Ewing Zhenghe Wang | 2014 | Acta Biochimica et Biophysica Sinica2014，46，3： | 2 |

| 3 | Analysis of black soil compaction with driver-agricultural machinery-soil system under corn sowing with high-power tractor in Northeast China显示文摘Soil compaction leads to crop yield reduction in Northeast of China.The interaction mechanism of driveragricultural machinery-black soil is not clear.A comprehensive field experiment of 4 hm2 of maize seeding was carried out in Baiquan County Cooperative.The results showed that the average increase rates of soil compaction before and after sowing were 118.82%and 71.02%.The SEM showed that waist fatigue had the greatest impact on soil compaction,and the unit fatigue of waist caused 1.51 and 1.27 unit compactions to the soil at the depths of 10 cm and 20 cm.The neck,waist,arm and leg fatigue of drivers increased the surface soil compaction by 1.83,1.76,1.78 and 1.55 units,and the deep soil compaction by 1.65,1.58,1.60 and 1.40 units.The results can provide a reference for the integration of human factor efficiency and conservation tillage. | Xiao Yang Zhiqiang Zhai Weijie Guo Wenjie Li Minli Yang Zhenghe Song | 2023 | International Journal of Agricultural and Biological Engineering2023，16，4： | 0 |
| 4 | Design and experiment of a high-clearance self-propelled sprayer chassis显示文摘A large high-clearance self-propelled sprayer chassis was designed according to the requirements of the sprayer’s driving operation and the overall goal.The structural characteristics and working principle of the chassis drive system,suspension system,track adjustment system,and frame were analyzed.A finite element analysis of the frame was carried out under four extreme conditions:full load bending,full load torsion,full load emergency braking and full load emergency turning.Under these four conditions,the maximum stress values of the frame were 149.45 MPa,219 MPa,151.44 MPa,and 123.27 MPa respectively,and the maximum strain values were 1.12 mm,2.22 mm,0.95 mm,and 1.16 mm respectively.A theoretical analysis of the stability,steering ability,and obstacle navigation of the sprayer chassis was conducted.The results showed that the upper angleθlim,lower angleθ׳lim and lateral limit tumbling angleφlim of the sprayer chassis were 50.1°,30.0°and 35.3°respectively.The minimum turning radius of the chassis was 5816 mm,and the minimum turning width was 4113 mm.The maximum obstacle crossing heights of the front and rear wheels were 466 mm and 457 mm.The theoretical analysis showed that the designed chassis met the field management operations of large plots.A field experiment of the high-clearance self-propelled sprayer chassis at full load was conducted.The experimental results were consistent with the theoretical analysis results.The sprayer chassis not only good handling stability but also good ride comfort.The results of this study provide references for the design of high-clearance self-propelled sprayer chassis. | Yu Chen Enrong Mao Wei Li Shuo Zhang Zhenghe Song Shanju Yang Jun Chen | 2020 | International Journal of Agricultural and Biological Engineering2020，13，2： | 0 |
