| 1 | A study of hydrate plug formation in a subsea natural gas pipeline using a novel high-pressure flow loop显示文摘The natural gas pipeline from Platform QK18-1 in the southwest of Bohai Bay to the onshore processing facility is a subsea wet gas pipeline exposed to high pressure and low temperature for a long distance. Blockages in the pipeline occur occasionally. To maintain the natural gas flow in the pipeline, we proposed a method for analyzing blockages and ascribed them to the hydrate formation and agglomeration. A new high-pressure flow loop was developed to investigate hydrate plug formation and hydrate particle size, using a mixture of diesel oil, water, and natural gas as experimental fluids. The influences of pressure and initial flow rate were also studied. Experimental results indicated that when the flow rate was below 850 kg/h, gas hydrates would form and then plug the pipeline, even at a low water content (10%) of a water/oil emulsion. Furthermore, some practical suggestions were made for daily management of the subsea pipeline. | Li Wenqing Gong Jing Lü Xiaofang Zhao Jiankui Feng Yaorong Yu Da | 2013 | Petroleum Science2013，10，1： | 11 |

| 19 | Screening of Brown Planthopper Resistant miRNAs in Rice and Their Roles in Regulation of Brown Planthopper Fecundity显示文摘MicroRNAs(miRNAs)can participate in plant-insect interactions,which regulate plant defense networks.In this study,we analyzed the miRNA expression profiles of six rice varieties before and after brown planthopper(BPH)-feeding.We identified 45 differentially expressed miRNAs between BPH-susceptible and BPH-resistant rice varieties and 144 miRNAs that responded to BPH-feeding.Thus,miRNAs may be involved in multiple pathways regulating rice defense response against BPH.In addition,we found that the genetic history of rice varieties determined the regulation mode of the miRNA and affected the amounts,types,changing trends and response periods of miRNAs in response to BPH-feeding.To conclude,we scanned seven potential cross-kingdom miRNAs,of which miR5795 may target the vitellogenin gene in BPH,causing a 16.07%reduction in BPH oviposition.The results provide new miRNA information of rice-BPH interactions and BPH-resistant rice variety breeding. | LÜJun LIU Jinhui CHEN Lin SUN Jiawei SU Qin LI Shihui YANG Jianhua ZHANG Wenqing | 2022 | Rice science2022，29，6： | 1 |
