以酵母双杂交系统筛选与糖基转移酶相互作用的蛋白质

用N－乙酰氨基葡萄糖基转移酶Ⅲ（GNTⅢ）β1,4－半乳糖基转移酶Ⅱ（GTⅡ）作诱饵,以酵母双杂交系统分别从胎肝cDNA文库中筛选到一种能与GNTⅡ发生相互作用的蛋白质,筛选到两种能与GNTⅢ发生相互作用的蛋白质。与Ⅲ作用的是早幼粒细胞白血病锌指蛋白（PLZF）,属于视黄酸受体家族的一种转录因子。提出了一种新的相互作用假设模型：PLZF是GNTⅢ的底物之一。另发现纤粘蛋白（FN）与GTⅡ作用,并推测此相互作用参与了细胞粘附。以上两种相互作用都是已知蛋白间的未知相互作用。还发现GTⅡ与由新基因编码的蛋白相互作用。     

17β-雌二醇及类似物与功能单体的相互作用

考察了17β-雌二醇（17β-E）及结构类似物与甲基丙烯酸甲酯（MMA）、甲基丙烯酸（MAA）和三氟甲基丙烯酸（TFMAA）等六种单体的相互作用。分别用紫外光谱 （UV）、红外光谱 （IR）和高效液相色谱 （HPLC）表征了用各单体的乙腈溶液分别与模板的相互作用和用沉淀聚合的分子印迹聚合物（MIP）的特性。结果表明,在全紫外聚合中,印迹17β-E 的TFMAA-co-TRIM聚合物的O—H振动吸收峰红移出现在聚合16h之后,C==O振动吸收峰则在聚合24h后发生红移。三种测试方法均证实TFMAA对17β-E有强相互作用,TFMAA-co-TRIM对雌二醇异构体（17β-E/17α-E）的印迹因子（IF）达到了3.01,分离因子α为2.28,具有良好的选择性。利用紫外法可初步检测各单体的乙腈溶液与模板相互作用强弱,再合成MIP,进行IR和HPLC表征,有助于筛选到对17β-E及结构类似物具有强相互作用的功能单体。     

HAF/NR复合材料中填料/基体界面相互作用的控制及其对橡胶补强的影响

采用含有吡啶官能团的分子对高耐磨炭黑粒子（HAF）原位接枝改性调控填料/基体界面相互作用。采用Ayala参数定量计算填料/基体界面相互作用,研究了界面相互作用对天然橡胶（NR）补强性能的影响。复合材料的拉伸应力-应变曲线表明,填充接枝炭黑的复合材料具有更高的力学性能,其原因是炭黑接枝增强了填料-基体界面相互作用,削弱了填料-填料相互作用。

人工神经网络在肽的定量构效关系研究中的应用

本文作者用人工神经网络模型和“相互作用”法研究了几种肽分子的定量构效关系（QSARs）。“相互作用”法是一种新的表征肽分子结构的方法，它认为：（1）在肽分子链中，任何两个氦基酸分子间都存在相互作用；（2）氦基酸分子间存在的相互作用值不仅与核酸分子类型有关，而且与它们间的距离有关系；（3）肽分子的结构可以用TIV值（即肽分子中任意两个氨基酸分子间存在的相互作用值之和）来表征。这种方法的优点是不同的肽分子的结构都可以由TIV值表征，它有助于更方便地研究肽分子的定量构效关系。计算结果和实验结果的比较证明这种方法的效果令人满意。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
