"鲁迅影像"作品中的绍兴空间,是"鲁迅影像"中最稳定、最成熟和最明确的空间意象。这一空间在电影文献纪录片、电视传记片和演剧传记片三种类型的作品中有不同的侧重和表达,体现了"鲁迅影像史"上不同的绍兴风貌。绍兴空间由风景、风物和... 详细信息

"鲁迅影像"作品中的绍兴空间,是"鲁迅影像"中最稳定、最成熟和最明确的空间意象。这一空间在电影文献纪录片、电视传记片和演剧传记片三种类型的作品中有不同的侧重和表达,体现了"鲁迅影像史"上不同的绍兴风貌。绍兴空间由风景、风物和风情三种不同符码组成,它们的编码规则代表着鲁迅形象的认知模式,并随着"鲁迅影像"定位和媒介影响而改变。绍兴空间也形成特定的程式:在画面和声音关系、绍兴空间的视线设置、处理人与物之间的关系及其影像内容的排序和比重都表现出一定规律性,也内涵着空间的权力秩序。绍兴空间意象内外视觉机制的形成从属于"鲁迅影像"建构,它具有为鲁迅形象的现代性目标诉求提供批判基础、构筑丰富情感的作品阐释空间和形成情绪氛围的功能。

针对Winkler地基梁模型的固有缺陷,将能够反映地基连续性的Pasternak双参数地基梁模型引入到锁脚锚管–钢拱架的联合承载分析中,考虑锁脚锚管与钢拱架之间的变形协调与荷载传递,采用结构力学和弹性地基梁理论推导锁脚锚管挠度、剪力、弯矩和地基反力的解析表达式。分别通过算例和工程实例考察不同地基基床系数和剪切刚度对锁脚锚管力学行为的影响规律,并与Winkler地基梁模型进行比较。结果表明:基床系数越小,2种模型计算所得锁脚锚管剪力、弯矩以及地基反力等的差异越明显;由双参数模型所得的地基反力数值较大,而且分布范围更小,主要集中在锁脚锚管端部附近区域;由双参数模型所得的隧道下沉量要小于Winkler模型的计算值。给出了适当减小锁脚锚管长度,并增大其直径的建议。研究成果可为软弱围岩隧道支护设计提供理论参考。

研究了瑞士乳杆菌Lactobacillus helveticus 6024经热激修饰后,与干酪成熟相关的生化性质变化及其对Cheddar干酪成熟的影响。结果表明:瑞士乳杆菌经70℃、10 s的热激处理后,在10%脱脂乳中经32℃、6 h培养后,其产酸能力仅为6.4%,而与干酪成熟密切相关的平均氨肽酶活力,仍有约25%的保留。热激处理后的菌株加入到干酪中对其组分没有显著影响,但对干酪可溶氮水平有不同程度的影响。与未添加热激菌株的干酪对照组相比,总可溶氮含量增加不显著,而在成熟3个月时5%磷钨酸可溶氮占总氮比例增加2倍,组间差异显著。干酪质构、微观结构分析的结果也证明,热激修饰菌株对促进干酪成熟具有促进作用。

Farming culture is the main part of Chinese outstanding traditional culture and also the important spiritual and cultural resources to construct the core values of the Chinese nation. In the new era, fully exploring and making full use of farming culture resources has important practical significance for the protection, inheritance and innovation of Chinese excellent traditional culture. The rapid development and successful brand shaping of Hani terrace tourism could provide experience for the exploration and utilization of farming culture tourism resources in other areas of China. Based on the analysis of development process of Hani terrace tourism as well as the successful experience of other regions for reference, ideas of developing farming culture tourism in the Dabie Mountains were proposed.

OBJECTIVE To observe the effect of curcumin on proliferation and apop-tosis in the prostate cancer LNCaP cell line. METHODS The AXSYMTM system luciferase method was used to examine the effect of various concentratious of curcumin on the content of prostate specific antigen (PSA) in prostate cancer LNCaP cells. A pGL3-PSA luciferase expression vector, containing 640 bp DNA of the PSA gene 5' -promoter region was constructed and transfected into the LNCaP cells with lipofectin. By measuring luciferase activity, the effect of 10 μmol/L, 20 μmol/L, 30 and 40 μmol/L curcumin on the promoter was studied. Effects on cell growth and apoptosis were analyzed by microscopy, the MTT colorimetric assay and flow cytometry. Western-blotting was used to measure expression of the androgen receptor (AR) in the LNCaP cells treated with different concentrations of curcumin. RESULTS The results showed that the expression of PSA was inhibited as curcumin reduced the activity of luciferase. Curcumin also caused a sigificant concentration-dependent decrease in AR expession measured by Western -blotting. Cell growth was inhibited and apoptosis was induced. CONCLUSION By inhibiting AR expression, curcumin reduced the function of the PSA promoter and inhibited PSA protein expression. Curcumin decreased the cellular proliferation and induced apoptosis in LNCaP cells in a concention-dependent manner.

Biphasic calcium phosphate （BCP） powders were prepared by hydrolyzation proc-ess and surface-modified by directly grafted L-lactide （LLA） onto the surface of BCP through a chemical linkage. The grafting ratio of organic groups was 9 wt%. After surface modification, the surface of BCP powders was covered by the lamella-shaped crystal. Poly （L-lactide） was mixed with BCP to form the BCP/PLLA biocomposite. Modified BCP （mBCP） particles could be uniformly dis-persed in PLLA matrix. The compressive strength of the mBCP/PLLA composite is 115 MPa, 28% higher than that of unmodified-BCP/PLLA composite. The improved mechanical strength is attributed to the enhanced adhesion between the inorganic BCP filler and the organic PLLA matrix.

Early stage expression of PR10 combined with phytoalexins contributed to Verticillium wilt resistance in cotton. In order to analysis the activities of PR10 proteins during pathogens’ infection, we cloned a Verticillium-induced PR10 (GbPR10-1) gene from cotton (Gossypium barbadense) and compared its expression patterns and domains with other PR10 proteins. Bioinformatics indicated that GbPR10-1 showed the lowest similarity with other 12 different PR10 genes in cotton (Upland and sea-island cotton). Expression profiles showed that GbPR10-1 gene instantly up-regulated after infection by V. dahliae in the sea-island cotton plants. GbPR10-1 was also induced by environmental stimulus including heat, submergence and salt, and ethylene but not by ABA and salicylic acid. The GbPR10-1 protein expressed in E. coli BL21 demonstrated that it had a low ribonuclease-like activity in vitro, and could inhibit V. dahliae hyphae growth but not its spores. Comparison analysis of GbPR10-1 (from resistant species) and GhPR10-1 (from susceptible species) responding to V. dahliae infection, only GbPR10-1 gene was strongly induced in the sea-island cotton plants (incompatible response), indicating that PR10-1 genes was linked to resistance signal. In summary, the earlier activation of GbPR10-1 gene, as the index of resistance response, would be aid to block

ZVS移相全桥变换器运行时超前桥臂和滞后桥臂开关管损耗明显不同,使得大功率变换器散热器设计困难,且影响了变换器的可靠运行。本文在分析ZVS移相全桥变换器超前桥臂和滞后桥臂开关管损耗基础上,提出一种等损耗PWM控制策略,使超前桥臂和滞后桥臂开关管达到等损耗运行的效果。最后将该控制策略成功地应用于一台大功率电镀电源,验证了其可行性。
