In this study,Ni catalysts supported on Pr-doped Ce O_(2) are studied for the CO_(2) methanation reaction and the effect of Pr doping on the physicochemical properties and the catalytic performance is thoroughly *** is shown,that Pr^(3+)ions can substitute Ce^(4+)ones in the support lattice,thereby introducing a high population of oxygen vacancies,which act as active sites for CO_(2) *** doping can also act to reduce the crystallite size of metallic Ni,thus promoting the active metal *** performance evaluation evidences the promoting effect of low Pr loadings(5 at%and 10 at%)towards a higher catalytic activity and lower CO_(2) activation *** the other hand,higher Pr contents negate the positive effects on the catalytic activity by decreasing the oxygen vacancy population,thereby creating a volcano-type trend towards an optimum amount of aliovalent substitution.

Dear Editor,A major function encoded in plant genome sequences is devoted to defense against pests and pathogens. Among the defenserelated functions in the plant genomes sequenced, there is a group of genes coding for NBS-LRR proteins that have been associated with effector-triggered immunity （Jones and Jones, 1997）. The majority of genes responsible for race-specific resistance in plants belong to this family.

A set of 100 segmented and skeletonised human retinal images,corresponding to normal states of the retina were studied.

The multifractal analysis of digital retinal images was made with computer algorithms,applying the standard boxcounting method. Statistical analyses were performed using the Graph Pad In Stat ***：The architecture of normal human retinal microvascular network was able to be described using the multifractal geometry.

Effect of Mitochondrial Dysfunction on Carbon Metabolism and Gene Expression in Flower Tissues of Arabidopsis thaliana

We characterized the transcriptomic response of transgenic plants carrying a mitochondrial dysfunction induced by the expression of the unedited form of the ATP synthase subunit 9. The u-ATP9 transgene driven by A9 and APETALA3 promoters induce mitochondrial dysfunction revealed by a decrease in both oxygen uptake and adenine nucleo- tides （ATP, ADP） levels without changes in the ATIP/ADP ratio. Furthermore, we measured an increase in ROS accumulation and a decrease in glutathione and ascorbate levels with a concomitant oxidative stress response. The transcriptome analysis of young Arabidopsis flowers, validated by qRT-PCR and enzymatic or functional tests, showed dramatic changes in u-ATP9 plants. Both lines display a modification in the expression of various genes involved in carbon, lipid, and cell wall metabolism, suggesting that an important metabolic readjustment occurs in plants with a mitochondrial dysfunction. Interestingly, transcript levels involved in mitochondrial respiration, protein synthesis, and degradation are affected. More- over, the levels of several mRNAs encoding for transcription factors and DNA binding proteins were also changed. Some of them are involved in stress and hormone responses, suggesting that several signaling pathways overlap. Indeed, the tran- scriptome data revealed that the mitochondrial dysfunction dramatically alters the expression of genes involved in signaling pathways, including those related to ethylene, absicic acid, and auxin signal transduction. Our data suggest that the mitochondrial dysfunction model used in this report may be useful to uncover the retrograde signaling mechanism between the nucleus and mitochondria in plant cells.

研究了由静力外荷载而导致的结构初始平面内变形和剪切弹性对双向对称的薄壁组合梁动力特性的影响。分析采用了基于大位移和转角的几何非线性理论。采用里兹法(Ritzmethod)对控制方程进行离散,并采用一种分析法来获得结构的自振频率。研究中梁被施加以均衡的初始弯矩、分布荷载和集中荷载。数字结果表明:当短轴的弯曲刚度与长轴的弯曲刚度的比值较大时,由于初始位移的影响,传统的振动分析方法可能会导致不准确的预测。此外,对不同的层状叠合材料结构,对跨长和影响荷载作用点高度也进行了研究。

简史这座文化宫由布加勒斯特建筑师victor Smigelschi于1930年设计,最初是为了举办阿斯特拉文化协会的活动。在20世纪60年代早期,这栋文化宫经历了第一次改造,它的主厅被改建为剧院。同期二楼也进行了功能调整,以便容纳布拉日历史和民俗博物馆、小镇图书馆和布拉日有线广播中心。但是1995年冬天的一场大火烧毁了大部分的建筑,对屋顶和大厅破坏尤为严重。2012年,市政厅启动了对这栋损毁建筑的重建和修复工作,在此之前,这里都是一片废墟。设计部分包括一个可以使用人工照明和自然照明的多功能厅,音乐会、晚会、戏剧演出、会议、展览等文化活动都可以在这里举行。建成后,这栋建筑也将作为罗马尼亚学院阿尔巴(Alba)分院的总部。
