大英帝国主义成为一些小说的最基本的意识形态架构,本文试图就把握这类小说精要的几个关键问题进行探讨。本文在简要梳理帝国历史的当下延续之后,在第二节中提出了"帝国虚构"这一术语并探讨了其意义。第三节则梳理了虚构与现实、文化与帝国主义之间的关系,着重分析了虚构作品在帝国主义意识形态小说的建构和解构中所扮演的创造性或表演性角色。第四节从叙事学的角度对殖民话语分析与后殖民批评进行了修正,这正是本文力图传达的方法。第五节讨论了文学性虚构和观念性虚构在建构和解构帝国主义思想方面所起到的六大功能,随后得出全文结论。

AIM: To explore the role of the adaptor molecule in liver regeneration after partial hepatectomy (PH). METHODS: We used transgenic mice expressing an n-terminal truncated form of MORT1/FADD under the control of the albumin promoter. As previously shown, this transgenic protein abrogated CD95- and CD120a-mediated apoptosis in the liver. Cyclin A expression was detected using Western blotting. ELISA and RT-PCR were used to detect IL-6 and IL-6 mRnA, respectively. DnA synthesis in liver tissue was measured by BrdU staining. RESULTS: Resection of 70% of the liver was followed by a reduced early regenerative response in the transgenic group at 36 h. Accordingly, 36 h after hepatectomy, cyclin A expression was only detectable in wild-type animals. Consequently, the onset of liver mass restoration was retarded as measured by MRI volumetry and mortality was significantly higher in the transgenic group. COnCLUSIOn: Our data demonstrate for the first time an involvement of the death receptor molecule MORT1/ FADD in liver regeneration, beyond its well described role as part of the intracellular death signaling pathway.

1987年5月至12月,在联邦德国哥廷根森林中,位于树冠不同高度上完成了气态硝酸浓度分布的测定。同时,还测定了森林中大气扩散参数。用模式计算出气态硝酸的沉降速度和沉降通量。结果表明,气态硝酸沉降通量平均约为26kg HnO_3—n/a·ha,气态硝酸浓度平均约为0.88μgHnO_3—n/m^3,夜间浓度下降,43m处(树冠上面)气态硝酸浓度高于33m(树冠中)。在第1至第10个实验里气溶胶中气态硝酸与硝酸盐的比值是0.3,而在第11～14个实验中约为1～3。

AIM： To approach the elusive function of the SLA/LP molecule, we have characterized genomic organization and conservation of the major antigenic and functional properties of the SLA/LP molecule in various species. METHODS： By means of computational biology, we have characterized the complete SLA/LP gene, mRnA and deduced protein sequences in man, mouse, zebrafish, fly, and worm. RESULTS： The human SLA/LP gene sequence of approximately 39 kb, which maps to chromosome 4p15.2, is organized in 11 exons, of which 10 or 11 are translated, depending on the splice variant. Homologous molecules were identified in several biological model organisms. The various homologous protein sequences showed a high degree of similarity or homology, notably at those residues that are of functional importance. The only domain of the human protein sequence that lacks significant homology with homologous sequences is the major antigenic epitope recognized by autoantibodies from autoimmune hepatitis （AIH） patients. COnCLUSIOn： The SLA/LP molecule and its functionally relevant residues have been highly conserved throughout the evoluti n, suggesting an indispensable function of the molecule. The finding that the only non-conserved domain is the dominant antigenic epitope of the human SLA/LP sequence, suggests that SLA/LP autoimmunity is autoantigen-driven rather than being driven by molecular mimicry.

叙事学与伦理批评的研究路径既非同床异梦,亦非相互忽视、格格不入。本文将叙事理论与伦理批评视为携手联姻的同盟者,认为二者的概念及视角可以相互补充、相互启发,从而更加有效地解读叙事形式的伦理与政治。文章在简述叙事学和伦理批评的不同发展轨迹以及近期学界之于二者整合研究的基础上,重点讨论伦理叙事学架构的基本前提和核心概念。伦理叙事学将叙事理论用于叙事虚构作品的分析和阐释,聚焦于叙事之于传播规范与价值的作用。两种批评方法的整合势必能给当下文学研究的再概念化以及文学伦理批评的不断发展提供重要的动力和支撑。

In the present paper, some novel opportunities for the development of high-efficient Si and III-V-based solar cells are considered: energy-saving environment friendly low-temperature technology of forming p-n junctions in Si (1), elaboration of structurally perfect GaAs/Ge/Si epitaxial substrates (2) and application of protective antireflecting coatings based on cubic zirconia (3). As a result: 1) new technique of forming p-n junctions in silicon has been elaborated. The technique provided easy and comparatively cheap process of production of semiconductor devices such as solar cells. The essence of the technique under the study is comprised in formation p-n junctions in silicon by a change of conductivity in the bulk of the sample occurring as a result of redistribution of the impurities, which already exists in the sample before its processing by ions. It differs from the techniques of diffusion and ion doping where change of conductivity and formation of p-n junction in the sample occur as a result of introduction of atoms of the other dopants from the outside;2) The conditions for synthesis of GaAs/Ge/Si epitaxial substrates with a thin (200 nm) Ge buffer layer featured with (1 - 2) × 105 cm-2 density of the threading dislocation in the GaAs layer. Ge buffer was obtained by chemical vapor deposition with a hot wire and GaAs layer of 1 μm thick was grown by the metal organic chemical vapor deposition. Root mean square surface roughness of GaAs layers of the less than 1 nm and good photoluminescence properties along with their high uniformity were obtained;3) The conditions ensuring the synthesis of uniform functional (buffer, insulating and protective) fianite layers on Si and GaAs substrates by means of magnetron and electron-beam sputtering have been determined. Fianite films have been shown to be suitable for the use as an ideal anti-reflecting material with high protective and anticorrosive properties.

目的通过现代有限元方法研究牙周膜上的静平衡应力状态。方法提出了两种用于分析牙周膜应力状态的有限元方法,把牙周膜看做是整个下颌模型的一部分,通过有限元方法来处理仿真的牙齿并加载,来研究牙周膜对牙周组织的应力应变分布的作用,计算得到的静平衡应力和牙齿根吸收状态进行比较。结果牙周膜的最大应力发生在接近最高点位置,在中跟位置附近存在局部最大应力,而牙周膜顶点区域的应力要大于牙周膜中根附近的局部最大应力。齿槽顶部的舌侧牙周膜部位可以发现静平衡应力。静平衡应力是和位置有关的,有静平衡应力的部位就会发生牙根吸收。结论人类切牙和单根前臼齿一样,植入物会导致其牙周膜顶点附近静平衡应力的增长,这一点同之前的发现相一致。人类切牙根吸收经常作用于牙周膜的顶点部位。
