| 1 | Comprehensive test stand for high-intensity cyclotron development显示文摘A comprehensive test stand for high-intensity cyclotron development,a 10 MeV 430 μA cyclotron,has been successfully constructed at China Institute of Atomic Energy (CIAE) for the experimental verification of the viability of a 100 MeV high-intensity cyclotron (CYCIAE-100) being constructed at CIAE.The verification includes the overall design technology,detail design and engineering technology for the crucial parts of the machine,e.g.main magnet and beam diagnostics.It will also pave the way for future enhancement of the beam intensity.The test stand consists of a H-ion source,axial injection system,central region,main magnet and coil,RF resonator,stripping extraction,and auxiliary systems,which include the RF power amplifier,high voltage and DC power supplies,electric apparatus,beam diagnostics,control,vacuum,water cooling,pneumatic system,and safety interlock.This paper presents the work regarding the design and sub-system development of the test sand,and the results of the beam commissioning of the machine. | ZHANG TianJue LI ZhenGuo CHU ChengJie XING JianSheng GUAN FengPing ZHONG JunQing JI Bin GE Tao YIN ZhiGuo HOU ShiGang PAN GaoFeng YAO HongJuan LU YinLong WANG ZhenHui WU LongCheng LIN Jun JIA XianLu WEI SuMin WEN LiPeng WANG Feng XIA Le CAI HongRu XIE HuaiDong CHEN RongFan ZHANG Yan ZHANG SuPing LIU GengShou ZOU Jian AN ShiZhong YANG JianJun BI YuanJie YANG Fang | 2011 | Chinese Science Bulletin2011，56，3： | 3 |
| 2 | Genome-wide identification and expression analysis of the GhIQD gene family in upland cotton(Gossypium hirsutum L.)显示文摘Background:Calmodulin(CaM)is one of the most important Ca^(2+)signaling receptors because it regulates diverse physiological and biochemical reactions in plants.CaM functions by interacting with CaM-binding proteins(CaMBPs)to modulate Ca^(2+)signaling.IQ domain(IQD)proteins are plant-specific CaMBPs that bind to CaM by their specific CaM binding sites.Results:In this study,we identified 102 GhIQD genes in the Gossypium hirsutum L.genome.The GhIQD gene family was classified into four clusters(Ⅰ,Ⅱ,Ⅲ,andⅣ),and we then mapped the GhIQD genes to the G.hirsutum L.chromosomes.Moreover,we found that 100 of the 102 GhIQD genes resulted from segmental duplication events,indicating that segmental duplication is the main force driving GhIQD gene expansion.Gene expression pattern analysis showed that a total of 89 GhIQD genes expressed in the elongation stage and second cell wall biosynthesis stage of the fiber cells,suggesting that GhIQD genes may contribute to fiber cell development in cotton.In addition,we found that 20 selected GhIQD genes were highly expressed in various tissues.Exogenous application of MeJA significantly enhanced the expression levels of GhIQD genes.Conclusions:Our study shows that GhIQD genes are involved in fiber cell development in cotton and are also widely induced by MeJA.Thw results provide bases to systematically characterize the evolution and biological functions of GhIQD genes,as well as clues to breed better cotton varieties in the future. | DOU Lingling LV Limin KANG Yangyang TIAN Ruijie HUANG Deqing LI Jiayin LI Siyi LIU Fengping CAO Lingyan JIN Yuhua LIU Yang LI Huaizhu WANG Wenbo PANG Chaoyou SHANG Haihong ZOU Changsong SONG Guoli XIAO Guanghui | 2021 | Journal of Cotton Research2021，4，1： | 0 |
| 3 | Isolation and Identification of Pathogenic Bacteria Causing Bovine Subclinical Mastitis in Eastern Hebei Province显示文摘In this study, the milk samples of 1 021 cows in eight dairy farms in Eastern Hebei Province were collected and detected with LMT reagent and somatic cell count for subclinical mastitis. Pathogenic bacteria in subclinical mastitis positive milk samples were isolated and identified.The results showed that 60.63%(619/1 021) of the sampled cows were diagnosed with subclinical mastitis, and mixed infections accounted for 88.21%(546/619) of the cases. In addition, 82 strains of 14 species were isolated from the subclinical mastitis positive milk samples, including 36 strains of Staphylococcus(43.90%), 33 strains of Streptococcus(40.24%), 8 strains of Enterobacteriaceae(9.76%) and 5 strains of Corynebacterium(6.10%), respectively. The results proved that Staphylococcus aureus and Streptococcus agalactiae are the main pathogenic bacteria causing bovine subclinical mastitis in Eastern Hebei Province. | Gao Guisheng Wu Tonglei Zhang Zhiqiang Yang Zongze Fu Zhixin Zou Fengping Gao Guangping An Jiwei Yao Weiping Shi Qiumei | 2018 | Animal Husbandry and Feed Science2018，10，1： | 0 |
