1西瓜果肉番茄红素含量及果实相关性状QTL分析显示文摘目的与意义:番茄红素是重要的天然类胡萝卜素,对人体具有保健作用,同时也是红色果肉西瓜中的主要色素,是决定西瓜果实品质的重要因素之一.栽培西瓜较低的DNA多态性阻碍了高质量遗传图谱的构建和番茄红素含量主效QTL的研究.该研究中,笔者成功地利用自行开发的CAPS标记构建了一个包含16个连锁群的西瓜遗传连锁图谱,该图谱将有利于西瓜果肉番茄红素含量关键基因确定及其克隆的进一步研究,同时为西瓜果肉番茄红素含量分子育种提供行之有效的分子标记.王超楠 刘识(编译) 高鹏 王学征 Angela R.Davis Abdul Majeed Baloch 栾非时 2019中国瓜菜2019,32,8:3

3Fish assemblages in protected seagrass habitats:Assessing fish abundance and diversity in no-take marine reserves and fished areas显示文摘Marine reserves are an important management tool for conserving local biodiversity and protecting fragile ecosystems such as seagrass that provide significant ecological functions and services to people and the marine environment.With humans placing ever-growing pressure on seagrass habitats,marine reserves also provide an important reference from which changes to seagrass and their ecological assemblages may be assessed.After eight years of protection of seagrass beds(Posidonia australis)in no-take marine reserves(Sanctuary Zones)within the Jervis Bay Marine Park(New South Wales,Australia;zoned in 2002),we aimed to assess what changes may have occurred and assess continuing change through time in fish assemblages within these seagrass meadows.Using baited remote underwater videos(BRUVs),we sampled seagrass fish assemblages at three locations in no-take zones and five locations in fished zones three times from 2010 to 2013.Overall,we observed a total of 2615 individuals from 40 fish species drawn from 24 families.We detected no differences in total fish abundance,diversity,or assemblage composition between management zones,although we observed a significant increase in Haletta semifasciata,a locally targeted fish species,in no-take marine reserves compared with fished areas.Fish assemblages in seagrass varied greatly amongst times and locations.Several species varied in relative abundance greatly over months and years,whilst others had consistently greater relative abundances at specific locations.We discuss the potential utility of marine reserves covering seagrass habitats and the value of baseline data from which future changes to seagrass fish populations may be measured.Rhiannon S.Kiggins Nathan A.Knott Tristan New Andrew R.Davis 2020Aquaculture and Fisheries2020,5,5:1

8对用虫螨磷处理出口谷物的评价显示文摘用相应的化学处理措施防治害虫侵染谷物能得到很好的保护。在美国,用马拉硫磷作为谷物杀虫剂来防治仓储害虫已被广泛地使用了近30年。但是,目前由于害虫产生抗药性而使其逐渐失去效力。实践证明了虫螨磷对马拉硫磷有抗药性的害虫是有毒力的,必将有效地取代马拉硫磷。该杀虫剂是一种对哺乳动物有广泛安全性的有机磷酸脂(急性胃毒半数致死量为2.050mg/kg)。L.M.Redlinger J.LZettler R.Davis R.A.Simonaiter 黄庆林 1991植物检疫1991,5,3:0
9Comparison of the VO_(2)Master Pro and Cosmed K5 During Walking,Jogging,and Running显示文摘Aim Portable devices that accurately detect the composition of expired gases and changes in VO_(2)open new possibilities in research methodology and accessibility.Purpose The purpose of this study was to compare the oxygen consumption(VO_(2))measurements of the VO_(2)Master Pro(VM)to the Cosmed K5(K5)during walking,jogging,and running in field and lab conditions.Methods Twelve proficient runners,with a current 10 k pace of≥11.29 km/h,performed 3 matched intervals at 3 different speeds(4.82,8.05,11.29 km/h)on a treadmill and on an outdoor track.An airflow test was also performed on both devices by pumping air through the devices using a 3 L syringe timed to a metronome at 15,25,and 35 beats/min.Results The VM did not report walking data for most participants.During treadmill running,there were significant differences in VO_(2)(47.86±3.94 vs.29.56±4.15 mL/kg/min),ventilation(V_(e))(71 vs.57 mL/min),and tidal volume(TV)(1.89 vs.1.56 L)between the K5 and VM respectively(P<0.05).Outdoor analysis also showed significant differences between devices in VO_(2),V_(e),and TV(P<0.05).The airflow test showed significant differences between the devices in V_(e)and TV(P<0.05).Conclusion These results suggest that there are significant discrepancies between the K5 and the VM,likely due to differ-ences in TV measurement.Alex Toulouse Dustin Joubert Gary Oden Patrick R.Davis 2022Journal of Science in Sport and Exercise2022,4,2:0
10Windows 95的由来显示文摘Windows是指Microsoft用于IBM PC的基于窗口的一系列操作系统。 操作系统是控制整个计算机的程序。比如,MS-DOS就是一个操作系统。Windows 95是Windows家族中最新的一员,它可使操作者执行其他的程序,那些程序称为应用程序,或简称“apps”。Stephen R.Davis 薛荣华 1996今日电子1996,,3:0
11美国出口农产品的检验及熏蒸处理显示文摘近十年来,美国农产品出口大幅度增长,出口货物的害虫感染问题困扰着贸易各方。美国农产品出口前都是分散储存在全国各地,没有办法统一实施检验和灭虫处理。为了贸易各方的利益。R.Davis 高崇省 1993植物检疫1993,7,2:0
