The presence of deoxynivalenol （don）, total aflatoxins, ochratoxin （OTA） and zearalenone （ZeA） was investigated in malting barley samples harvested in Romania using an eLISA method （VeRATOX, Neogen）. In 7 out of 14 barley samples the aflatoxins were not found at detectable levels （50%）. In 9 out of 14 barley samples the OTA was not found at detectable levels （64.29%）. In 1 out of 14 barley samples the don was not found at detectable levels （7.14%）. In 13 out of 14 barley samples （92.86%） the ZeA was above the acceptable limit （100μg/kg）. For all barley samples the aflatoxins, don and OTA were in line with european Union regulations in force （4.0 μg/kg for aflatoxins, 1,250.0μg/kg for don, 5.0 μg/kg for OTA, respectively）.

＜正＞In this paper,we propose a new non-volatile FPGA circuit based on Spin-RAM technology（Spin Transfer Torque Magnetisation Switching RAM）,new generation of MRAM（Magnetic RAM）.This Spin-RAM based FPGA circuit could process securely the information in low power dissipation and high speed;meanwhile all the data processed are stored permanently in the distributed Spin-RAM *** this non-volatile FPGA design, MTJs（Magnetic Tunnel Junction） are used as storage *** to conventional MRAM circuits we don’t use a complex sense amplifier,but a simple SRAM based sense amplifier couples two MTJs per *** non-volatility of Spin-RAM allows the dynamical configuration of FPGA circuits and the start-up time of circuit can be decreased up to some hundred pico *** conventional MRAM,the MTJs of Spin-RAM will be on the semiconductor surface;therefore the circuit die area will not be enlarged comparing with the conventional FPGA.

作者： Chen Danhua, Cai Ruxiu and Zeng Yun’e(Department of Chemistry, Wuhan University, Wuchang)

The automatic determination of the total rare earths in the aluminium-rare earth alloys was studied by using our recently designed automated flow injection device and the high sensitive and selective rare earth reagent-DBC-CPA (2 -(2-phosphono-4-chlorophen-ylazo)-7-(2,,6-dibromo-4-chlorophenylazo)-1,8-dihydroxy-3, 6 - dis-ulfonaphthalene). The automated flow injection device consists of an Apple Ⅱ microcomputer, two peristaltic pumps and a spectrophoto-meter. It has good automatic degree and high producibility, the sampling volume and rotation velocity of the pumps can be changed continuously and automatically. The total rare earths in aluminium-rare earth alloys were automatically determined at 645nm wavelength in the medium of ***/L HC1 and 1% H2C2O4 . Fe Cu, Al, Mg, Ni, Zn and Cr don’t interfere with the determination and temperature has no effect on the sensitivity in the range of 10-49℃ above zero. The calibration curves for cerium group and yttrium group rare earths are close to each other. T

目的探讨泌尿系感染病原菌的分布及耐药状况,为临床诊断和治疗泌尿系感染疾病提供可靠的依据,指导临床合理用药。方法回顾性分析近2年来本院住院及门诊泌尿系感染患者尿培养结果,分离出382株病原菌进行鉴定和耐药性分析。结果病原菌以革兰阴性杆菌为主,占70.0%以上。革兰阴性杆菌中大肠埃希菌检出率最高,占50.3%;其次为肠球菌属,占13.7%,且比例有逐渐升高趋势。大肠埃希菌对亚胺培南耐药率最低,为2.6%,而对大部分β-内酰胺类药物的耐药率大于35.0%;肠球菌属耐药率为38.0%～90.0%,对万古耐药率为3.8%。结论泌尿系感染主要病原菌为肠杆菌科细菌,对头孢菌素和喹诺酮类药物耐药率明显升高,临床应依据药敏试验结果合理选用抗菌药物,减少耐药性播散。

北美五大湖区的安大略湖北岸don Valley Brickyard、Scarborough Bluffs、Bowmanville Bluffs剖面共同构成了北美东北部最长也是最厚的陆地第四纪沉积记录,较完整地记录了晚更新世劳伦泰德冰盖(the Laurentide Ice Sheet)的演化.晚更新世劳伦泰德冰盖演化的重建有赖于这些经典剖面中重要沉积地层单元的准确年代学控制.传统的地层年代学主要是依靠少量14C年代,将主要的混杂堆积单元(diamicton)解释为气候变冷环境下的冰川扩张,并与指示全球冰量变化的深海氧同位素曲线一一比对建立起来的.这样建立起来的年代学存在很大的不确定性.20世纪80-90年代的少量热释光年代也不相吻合,最近的13个长石红外释光定年则只集中于Bowmanville Bluffs的一个分层,并未建立整个剖面的地层年代学,使这些经典沉积剖面的年代学一直没有得到系统的建立.应用石英光释光SAR-SGC法测试了Bow manville Bluffs剖面Glaciofluvial Sand单元的2个冰水沉积样品,年代结果分别为(41.6±3.8)ka、(48.1±4.4)ka,分析表明这一年代结果偏老,石英颗粒可能晒褪不完全.由于大测片无法识别晒褪不完全的颗粒,因此,测试更多的剖面序列的光释光年代并尝试采用粗颗粒小测片或单颗粒技术解决样品颗粒晒褪不完全的问题将是必要的.

The comparative analysis of the dielectric properties of bismuth-containing pyrochlores with different manifestation of atomic order/disorder was carried *** examined the dielectric properties(including behavior in electric fields)of two pyrochlore compounds:BZN(presumably a composition close to Bi_(1.5)Zn_(0.5)Nb_(1.5)O_(6.5))ceramics with chemical disorder in both A and B cation sublattices and Bi_(2)Ti_(2)O_(7)single crystal with fully chemical ordered *** fundamental differences between the dielectric properties of the BZN ceramics and Bi_(2)Ti_(2)O_(7)single crystal were *** particular,in the dielectric relaxation behavior(which cannot be described via Arrhenius law in the Bi_(2)Ti_(2)O_(7))or in the influence of the electric fields on the dielectric permittivity(split-ting of the field-cooled and zero-field-cooled behaviors was observed for Bi_(2)Ti_(2)O_(7)below estimated freezing temperature).The results of this study highlights the special role of Bi_(2)Ti_(2)O_(7)as a candidate material for studying aspects of geometric frustration related with pyrochlore structure in non-magnetic medium and specifies the future directions of research.

语言学习离不开大量阅读。英语专业泛读课程旨在通过倡导学生大量阅读英文书籍,帮助他们学会阅读,提高阅读理解能力,扩大知识面。传统的泛读课堂重知识轻阅读,重做题轻阅读,重课内轻课后,缺少阅读方法、技巧的系统讲授,导致学生阅读量小,阅读能力提高慢,知识面狭窄。因此,泛读课程教学改革应该充分强调大量阅读的重要性,推荐适合学生的阅读材料,传授阅读技巧方法,指导并监督学生课后大量阅读,并将学生课后自主阅读情况纳入课程考核体系。
