| 1 | Effect of wind field below unmanned helicopter on droplet deposition distribution of aerial spraying显示文摘Wind field is one of the important factors affecting the distribution characteristics of aerial spraying droplet deposition.In order to reveal the impact mechanism of droplet deposition distribution by the wind field below agricultural unmanned helicopter rotor,in this study,the wind field distribution below uniaxial single-rotor electric unmanned helicopter rotor was measured by using a wireless wind speed sensor network measurement system for unmanned helicopter.The effects of wind field in three directions(X,Y,Z)below the rotor on droplet deposition distribution were analyzed with the condition of aerial spraying droplet deposition in rice canopy,and the regression model was established via variance and regression analyses of experiment results.The results showed that,the wind field in Y direction had a significant effect on droplet deposition in effective spray area,the wind field in Z direction had an extremely significant effect on droplet deposition in effective spray area,and the corresponding significance(sig.)values were 0.011 and 0.000.Furthermore,the wind field in Z direction had a significant effect on the penetrability and uniformity of droplet deposition in effective spray area,the corresponding sig.values were 0.025 and 0.011 respectively.The wind speed in Y direction at the edge of effective spray area had a significant effect on droplet drift,the sig.value was 0.021.In addition,the correlation coefficient R of the regression model was 0.869 between droplet deposition in effective spray area and the wind speed in Y and Z directions,and 0.915 between the uniformity of droplet deposition in effective spray area and the maximum wind speed in Z direction.The result revealed the influencing mechanism of the wind field below the rotor of uniaxial single-rotor electric unmanned helicopter on the distribution of aerial spraying droplet deposition.The results can provide guidance for the actual production application of aerial spraying to reduce liquid drift and improve the utilization rate of pesticide. | Chen Shengde Yubin Lan Li Jiyu Zhou Zhiyan Liu Aimin Mao Yuedong | 2017 | International Journal of Agricultural and Biological Engineering2017,10,3: | 25 |

| 3 | Experimental study on moving boundaries of fluid flow in porous media显示文摘Researches on the boundary shape of fluid flow in porous media play an important role in engineering practices, such as petroleum exploitation, nuclear waste disposal and groundwater contamination. In this paper, six types of artificial porous samples (emery jade) with different porosities are manufactured. With the background of slow flow in porous media, laboratory experiments are carried out by observing the movement of five types of fluids with different dynamic viscosities in various types of porous media. A digital video recorder is employed to record the complete process of the fluid flow in the porous media. Based on the digital photos of the moving boundaries of fluid flow in porous media, the average displacement and fractal dimension of the moving boundary are estimated for different combinations of porosity and dynamic viscosity. Moreover, the evolution behavior of the average velocity and fractal dimension of the moving boundary with time is known. The statistical relations of the average velocity, the fractal dimension of the moving boundary and the porosity of porous media and the dynamic vis- cosity of fluids are proposed in this paper. It is shown that the front shape of the moving boundary of fluid flow in porous media is an integrated result of the porosity of porous media and the dynamic viscosity of fluids. | ZHOU HongWei ZHANG YaHeng LI AiMin QIU DaYong | 2008 | Chinese Science Bulletin2008,53,16: | 8 |

| 5 | Efficacy and safety of Reduqing granules in the treatment of common cold with wind-heat syndrome: a randomized, double-blind, double-dummy, positive-controlled trial显示文摘OBJECTIVE:To assess the efficacy and safety of Reduqing granules in patients with common cold with wind-heat syndrome(CCWHS).METHODS:A randomized, double-blind, double-dummy, parallel, positive-controlled trial included 72 CCWHS patients was performed.The participants were randomly assigned to two groups,Reduqing(RDQ) group and Lianhuaqingwen(LHQW) group, in a 1∶1 ratio.Patients in RDQ group received Reduqing granules and dummy Lianhuaqingwen capsules three times a day and patients in LHQW group received Lianhuaqingwen capsules and dummy Reduqing granules three times daily.The duration of treatment and follow-up were four days.RESULTS:There were no statistically significant differences in total markedly effective rate and total effective rate between RDQ group and LHQW group after treatment.Traditional Chinese Medicine(TCM) symptom score was significantly reduced after treatment in RDQ group, as well as in LHQW group.However, the difference of change in TCM symptom score between two groups was not statistically significant(P > 0.05).There were no significant differences between two groups in the median time to fever relief [RDQ group(4 ± 8) h vs LHQW group(4 ± 5) h] or the median time to fever clearance(RDQ group 47 h vs LHQW 36 h).No serious adverse events were reported during the study.CONCLUSION:Compared with Lianhuaqingwen capsules, Reduqing granules achieved similar therapeutic effect in the treatment of CCWHS and no drug-related adverse events were reported during the study.Therefore, Reduqing granules might be effective and safe in the treatment of CCWHS. | Ma Yanjiao Zhang Zhongyi Wei Lianbo He Shuai Deng Xun Ji Aimin Zhou Benjie Jiang Deqi Li Mingxing Wang Yong | 2017 | Journal of Traditional Chinese Medicine2017,37,2: | 5 |
| 6 | A novel aminated polymeric adsorbent for removing refractory dissolved organic matter from landfill leachate treatment plant显示文摘Refractory dissolved organic matter (DOM) from landfill leachate treatment plant was with high dissolved organic carbon (DOC) content. An aminated polymeric adsorbent NDA-8 with tertiary amino groups and sufficient mesopore was synthesized, which exhibited high adsorption capacity to the DOM (raw water after coagulation). Resin NDA-8 performed better in the uptake of the DOM than resin DAX-8 and A100. Electrostatic attraction was considered as the decisive interaction between the adsorbent and adsorbate. Special attention was paid to the correlation between porous structure and adsorption capacity. The mesopore of NDA-8 played a crucial role during uptake of the DOM. In general, resin in chloride form performed a higher removal rate of DOC. According to the column adsorption test, total adsorption capacity of NDA-8 was calculated to 52.28 mg DOC/mL wet resin. 0.2 mol/L sodium hydroxide solution could regenerate the adsorbent efficiently. | ZHANG Long, LI Aimin, WANG Jinnan, LU Yufei, ZHOU Youdong State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing 210093, China. | 2009 | Journal of Environmental Sciences2009,21,8: | 5 |
| 7 | Characterization of increased cuticular wax mutant and analysis of genes involved in wax biosynthesis in Dianthus spiculifolius显示文摘Cuticular wax formation on the surface of plant leaves is associated with drought-stress tolerance.The identification of wax biosynthesis-related genes will contribute to the genetic improvement of drought resistance in plants.In this study,we characterize a novel Dianthus spiculifolius mutant with increased cuticular wax.The mutant exhibited stronger drought resistance as indicated by less leaf wilting and death,higher leaf relative water content and water retention capacity,and slower water loss and chlorophyll extraction than did the wild type during drought treatment.In the mutant leaves,2730 upregulated and 2151 downregulated differentially expressed genes(DEGs)were identified by transcriptome sequencing.A wax biosynthesis pathway of the identified DEGs was significantly enriched.Finally,three key genes(DsCER1,DsMAH1,and DsWSD1)involved in wax biosynthesis were identified and verified by qPCR.These results suggest that differential expression of DEGs involved in wax biosynthesis may be associated with the increase in cuticular wax in the mutant.Taken together,our results help elucidate wax formation patterns in D.spiculifolius.Furthermore,the DEGs involved in wax biosynthesis identified here may be valuable genetic resources for improving plant stress tolerance through increased accumulation of cuticular wax. | Aimin Zhou Enhui Liu Jiao Liu Shuang Feng Shufang Gong Jingang Wang | 2018 | Horticulture Research2018,5,1: | 4 |
| 8 | Fabrication and its characteristics of hard coating Ti-Al-N system prepared by DC magnetron sputtering显示文摘Pseudobinary Ti 1 x Al x N films were synthesized on Si (100) wafer by DC magnetron sputtering method using Ti 1 x Al x alloy targets with different Al contents. The composition of the Ti 1 x Al x N films was determined by electron probe microanalysis (EPMA). Structural characteristic was performed by X-ray diffraction (XRD), transmission electron microscopy (TEM), and high-resolution TEM (HRTEM). First principles virtual crystal calculations for the Ti 1 x Al x N disordered alloys were used for the XRD simulations. The crystalline structure of the Ti 0.61 Al 0.39 N film was found to be a metastable single phase with NaCl (B1) structure. Its lattice constant, determined by XRD, was less than that of pure TiN. With the increase of Al content, the lattice constant of B1 phase was continually decreased, while würtzite (B4) structure was observed in the Ti 0.40 Al 0.60 N film. When x reached 0.75, the B1 phase disappeared, and only B4 phase was remained. The critical Al content for the phase transition from NaCl to würtzite structure in this paper was about 0.60, which could be explained by both the thermodynamic model and the electron theory. As-deposited Ti 1 x Al x N films exhibited excellent mechanical properties. Hardness measurements of Ti 1 x Al x N films showed a high value of 45GPa for x=0.39 and was decreased to value of 27 GPa with increasing Al at x=0.60. | Zhou, Xuyang Wu, Aimin Qu, Wenchao Jiang, Xin | 2012 | Rare Metals2012,31,2: | 3 |

| 10 | Human hepatopoietin augmenter of liver regeneration──A hepatotrophic factor for liver regeneration, and its potential antihepatitis effect in vivo显示文摘The effect of human hapatopoietin i.e. augmenter of liver regeneration (hALR) was determined on hepatocyte DNA synthesis, and on CCl 4-induced hepatitis in animal in vitro and in vivo. It is found that ALR could directly stimulate DNA synthesis of hepatocytes in primary culture in a dose-dependent manner. In 30% hepatectomied rats, significant DNA synthesis occurred in control rats ; even so, exogenous hALR gene encoding protein increased DNA synthesis of regeneration liver by 2.3 fold compared with control rats. A lower dose of CCl 4 was administrated in rats and the effect of ALR on DNA synthesis of regenerating liver 48 h after CCl 4 administration was analyzed. Few Budr-labeled hepatocytes were visible in control rats. However, exogenous hALR markedly increased the number of labeled cells in a dose-dependent manner. Statistical analysis showed that 10 or 40 μg·kg -1 ALR protein stimulated DNA synthesis by 1.7 and 4.8 fold respectively. In addition to enhancing cell growth, adiministration of hALR achieved a significant improvement in reversing the lethality of rat hepatic failure when compared with that of control group; the elevation of cytosolic enzymes was dramatically suppressed by exogenous hALR in CCl 4-treated mice in vivo and in vitro; histologically, hepatocytes around the central vein were necrotic, and the degree of hepatocyte necrosis in control mice was more prominent than that in the mice given 40 μg·kg-1 hALR 48 h after CCl 4 administration. We also noted that hALR had a strong antihepatitis effect in vitro which was determined with primary cultured rat hepatocytes. These findings suggest that hALR protects the integrity of hepatocytes against severe hepatitis, and indicate that ALR may be an important regulator of liver regeneration and play a major role in liver injury repair. It proves ALR adminstration to be a useful treatment to accelerate liver regeneration and to prevent the onset of hepatitis or intrahepatic cholestasis induced by toxin. | YANG Xiaoming 1, WANG Aimin 2, ZHOU Ping 3, XIE Ling 1, WANG Qingming 1, WU Zuze 1 and HE Fuchu 1 1.

| 11 | Reliable and Efficient Agrobacterium tumefaciens-Mediated Genetic Transformation of Dianthus spiculifolius显示文摘Dianthus spiculifolius is a perennial herbaceous flower with strong environmental adaptability and is an important ornamental ground cover plant.In this study,seeds of D.spiculifolius were used as explants for callus induction,adventitious bud differentiation,and rooting by adding different concentrations of 2,4-dichlorophenoxyacetic acid(2,4-D),6-benzyl aminopurine(6-BA),and naphthaleneacetic acid(NAA)to Murashige and Skoog medium.The calli generated were co-cultured with Agrobacterium tumefaciens EHA105 containing pBI121-GUS or pBI121-GFP plasmids for 30 min,and transgenic regenerated plants were obtained by kanamycin(30mg·L^−1)screening.RT-PCR confirmed the stable expression of the exogenous GUS and GFP genes in the D.spiculifolius.Theβ-glucuronidase(GUS)histochemical staining confirmed GUS gene expression in transgenic calli,adventitious buds,and regenerated plants of D.spiculifolius.The green fluorescent protein(GFP)visual analysis showed GFP gene expression in transgenic calli.Furthermore,subcellular localization analysis showed that the three organelle marker proteins were not only successfully expressed but also accurately localized to their corresponding organelles in D.spiculifolius callus cells.These results indicated a successful establishment of a reliable and efficient A.tumefaciens-mediated genetic transformation system,which will contribute to functional gene research and genetic improvement of D.spiculifolius. | Jingang Wang Shiyue Liu Hongping Ma Ye Tao Shuang Feng Shufang Gong Jinzhu Zhang Aimin Zhou | 2020 | Horticultural Plant Journal2020,6,3: | 2 |
| 12 | Methylesterification of cell-wall pectin controls the diurnal flower-opening times in rice显示文摘Flowers are the core reproductive organ of plants, and flowering is essential for cross-pollination. Diurnal flower-opening time is thus a key trait influencing reproductive isolation, hybrid breeding, and thermostability in plants. However, the molecular mechanisms controlling this trait remain unknown. Here, we report that rice Diurnal Flower Opening Time 1 (DFOT1) modulates pectin methylesterase (PME) activity to regulate pectin methylesterification levels of the lodicule cell walls, which affect lodicule swelling to control diurnal flower-opening time. DFOT1 is specifically expressed in the lodicules, and its expression gradually increases with the approach to flowering but decreases with flowering. Importantly, a knockout of DFOT1 showed earlier diurnal flower opening. We demonstrate that DFOT1 interacts directly with multiple PMEs to promote their activity. Knockout of PME40 also resulted in early diurnal flower opening, whereas overexpression of PME42 delayed diurnal flower opening. Lower PME activity was observed to be associated with higher levels of pectin methylesterification and the softening of cell walls in lodicules, which contribute to the absorption of water by lodicules and cause them to swell, thus promoting early diurnal flower opening. Higher PME activity had the opposite effect. Collectively, our work uncovers a molecular mechanism underlying the regulation of diurnal flower-opening time in rice, which would help reduce the costs of hybrid breeding and improve the heat tolerance of flowering plants by avoiding higher temperatures at anthesis. | Mumei Wang Xiaopei Zhu Guoqing Peng Minglong Liu Shuqing Zhang Minghao Chen Shitang Liao Xiaoying Wei Peng Xu Xiyu Tan Fangping Li Zhichuan Li Li Deng Ziliang Luo Liya Zhu Shuai Zhao Dagang Jiang Jing Li Zhenlan Liu Xianrong Xie Shaokui Wang Aimin Wu Chuxiong Zhuang Hai Zhou | 2022 | Molecular Plant2022,15,6: | 2 |
