基于Web of Science的河北大学科研论文统计分析

以Web of Science数据库为文献来源，利用文献计量学的方法，从文献年收录量、文献类型、语种、学科分布、作者分布、合作情况、来源期刊和引用情况等方面，对Web of Science收录河北大学2004—2013年的科研论文进行统计分析，结果表明：河北大学近10年来被Web of Science数据库收录的文献数量和被引频次呈现逐年上升的趋势，在化学、物理学、动物学和数学方面具有一定的科研能力和影响力，但同时应注重国际合作交流和文献的质量。     

地理国情普查地表覆盖内业解译的质量问题研究

地表覆盖内业解译是地理国情普查的一道重要工序。地理国情地表覆盖内业解译现存图斑平面位置精度不足、分类错误多种多样等普遍问题,问题突出典型。文中针对这些问题图文并茂、清晰明了的进行了说明,并从多方面分析问题产生的原因,提出加强对技术指标和采集原则的学习和理解,加强内业与外业的结合,充分发挥解译样本的作用等建议,以有效提高内业解译的质量。     

从作者性别批评视角看简·爱和吕蓓卡的人物形象差异

简·爱与《名利场》中的女主角吕蓓卡是英国维多利亚时期文学中两个具有同样独立反叛意识但被作者赋予不同命运结局的女人。从作者的性别视角去解读这两个传统女性形象的本质差异,能看出男女作者对女性反抗压迫行为的不同理解和价值判断,并能更好地发掘出被别的批评视角忽略或误读的文本内涵。     

Iodine(III)‐Catalyzed Rearrangements of Imides: A Versatile Route to α,α‐Dialkylated α‐Hydroxy Carboxylamides

A tertiary hydroxy group α to a carboxyl moiety comprises a key structural motif in many bioactive substances. With the herein presented metal‐free rearrangement of imides triggered by hypervalent λ³‐iodane, an easy and selective way to gain access to such a compound class, namely α,α‐disubstituted‐α‐hydroxy carboxylamides, was established. Their additional methylene bromide side chain constitutes a useful handle for rapid diversification, as demonstrated by a series of further functionalizations. Moreover, the in situ formation of an iodine(III) species under the reaction conditions was proven. Our findings clearly corroborate that hypervalent λ³‐benziodoxolones are involved in these organocatalytic reactions.     

南方丝绸之路对大理的影响及当前的对策

大理历史悠久,文化灿烂,风光秀丽,古道纵横。过去南方丝绸之路对大理的经济、政治、交通、文化、宗教等有较大的影响,今天在国家"一带一路"的大战略背景下,大理应该怎么办,大理学院应该怎么办,这是当代学人的新课题。以古代南方丝绸之路为出发点,建议今天大理的"一带一路"定位为交往之路、人情之路。     

A sensitive and efficient method for trace analysis of some phenolic compounds using simultaneous derivatization and air‐assisted liquid–liquid microextraction from human urine and plasma samples followed by gas chromatography–nitrogen phosphorous detection

In present study, a simultaneous derivatization and air‐assisted liquid–liquid microextraction method combined with gas chromatography–nitrogen phosphorous detection has been developed for the determination of some phenolic compounds in biological samples. The analytes are derivatized and extracted simultaneously by a fast reaction with 1‐flouro‐2,4‐dinitrobenzene under mild conditions. Under optimal conditions low limits of detection in the range of 0.05–0.34 ng mL^?1 are achievable. The obtained extraction recoveries are between 84 and 97% and the relative standard deviations are less than 7.2% for intraday (n = 6) and interday (n = 4) precisions. The proposed method was demonstrated to be a simple and efficient method for the analysis of phenols in biological samples. Copyright © 2015 John Wiley & Sons, Ltd.
