The genome sequence of Arabidopsis thaliana,a widely adopted model species,has greatly expedited plant molecular biology *** 20 years after the first release of the genome sequence(Arabidopsis Genome Initiative,2000),there remains unresolved gap regions that are presumably composed of highly repetitive sequences,such as telomeres,centromeres,5S rDNA clusters,and nucleolar organizerregions(NORs)containing 45S rDNA.

Because of the low access to biodegradable organic substances used for denitrification,the partial nitrification-denitrification process has been considered as a low-cost,sustainable alternative for landfill leachate *** this study,the process upgrade from conventional to partial nitrificationdenitrification was comprehensively investigated in a full-scale landfill leachate treatment plant(LLTP).The partial nitrification-denitrification system was successfully achieved through the optimizing dissolved oxygen and the external carbon source,with effluent nitrogen concentrations lower than 150 mg/***,the upgrading process facilitated the enrichment of Nitrosomonas(abundance increased from 0.4%to 3.3%),which was also evidenced by increased abundance of amoA/B/C genes carried by *** Nitrospira(accounting for 0.1%-0.6%)was found to stably exist in the reactor tank,considerable nitrite accumulation occurred in the reactor(reaching 98.8 mg/L),indicating high-efficiency of the partial nitrification ***,the abundance of Thauera,the dominant denitrifying bacteria responsible for nitrite reduction,gradually increased from 0.60%to 5.52%during the upgrade *** process caused great changes in the microbial community,inducing continuous succession of heterotrophic bacteria accompanied by enhanced metabolic potentials toward organic *** results obtained in this study advanced our understanding of the operation of a partial nitrification-denitrification system and provided a technical case for the upgrade of currently existing full-scale LLTPs.

Dear Editor,It has been more than 1 year since China reported the first case of African swine fever (ASF) infection in August2018, and the epidemic situation remains severe (China News Service 2019). According to reports from the Ministry of Agriculture and Rural Affairs, China has reported 160 cases of ASF, which resulted in nearly 1.2 million pigs being killed, as of November 21, 2019 (China News Service 2019).

选用双酚A型环氧树脂作为基料,酚醛胺等4种类型作为固化剂,配以高效促进剂(DMP-30)、铁粉及其他填料,制备出剪切强度高、耐介质性好的高性能双组分环氧铸工胶。重点考察了环氧树脂、固化剂、促进剂及铁粉对铸工胶性能的影响。研究结果表明:(1)随着环氧树脂E-44质量分数的增加,混合胶液的黏度不断提高,固化时间逐渐缩短,剪切强度随着E-44含量的增加先升后降,在质量分数为40%时剪切强度最大。本研究确定环氧树脂以E-44与E-51混合为主,E-44的质量分数在40%时相对最佳。(2)在其他组分用量不变的条件下,考察了脂环胺、聚酰胺、酚醛胺以及聚硫醇4种类型固化剂对胶液固化时间、硬度及剪切强度的影响,并考察了固化剂对胶液耐介质性的影响。研究结果表明,选用酚醛胺作为固化剂。(3)随着促进剂DMP-30添加量的增加,胶液的固化时间逐渐缩短,硬度逐渐变大,剪切强度则先增大后减小。本研究确定DMP-30的相对最佳添加量为4%。(4)随着3种(600、800、1250目)铁粉添加量的提升,胶液的剪切强度均先增大后减小,其中1250目铁粉提升胶液的剪切强度最为明显,并且在添加量为50%时达到峰值,最高剪切强度可达29MPa。本研究确定铁粉的目数为1250目,添加量为50%。
