A 78-year-old man with a history of mitral valve prolapse underwent echocardiography during his cardiological check-up examination in 2011 in a symptom-free stage. Echocardiography revealed akinesis of the inferior septum and inferobasal free wall as a novel finding suggesting a distal right coronary artery （RCA） lesion （Figure 1）. The systolic left ventricular function was normal. Earlier echocardiographies did not show wall motion abnormalities.

Land property in the post socialist countries was rebuilt in the beginning of the 1990s. The process went in different way in all of the post-socialist countries. The result of the privatization of agricultural land was a fragmented, direct or indirect smallholder ownership structure in most of the new member states of the EU. The land, partly or totally was given back to the owners and inheritors of land reforms following the war. it means that considerable proportion of the land is cultivated by tenants, the fragmented estate structure decreases the efficiency and the increasing rental fees further destroy the profitability and competitiveness of farming. Regarding to the competitiveness of agriculture, Poland showed a developing tendency after the accession, but Hungary suffers from serious problems. Applying descriptive statistics between the changes of land use and land ownership during the research relation analysis, emphasizing the effect in competitiveness of the land price and a land rent, the paper tries to identify the main differences and similarities in land use and property structure, and their effects on the agricultural competitiveness based on the FADN data base, since 2004-2007.

We recently described a new combinatorial strategy for modular catalyst development, one using self-assembly in the ligand scaffold-generating step to produce libraries of chiral self-assembled ligands. Metal-directed self-assembly of bifunctional subunits around a structural metal (typically zinc) can be used to form a heteroleptic complex in which a second set of ligating groups are suitably disposed to form a heterobimetallic catalyst system[1].

采用***非线性有限元软件,对试件在激光点热源作用下动态微变形过程进行了数值模拟。通过激光反射放大系统测量了试件在激光点热源作用下的动态微变形过程。模拟值与实测值的结果表明:热应力和相变应力的共同作用使得试件产生微变形,最终试件的变形方向取决于热应变和相变共同作用的结果,朝向激光束或背向激光束。比较实验值和模拟值,发现变形的最大值相近,变形过程却略有不同。考虑到激光点热源作用下有限厚度的试件内,温度场分布出现的反常效应,即内部的温度大于边界温度,提出采用波动理论修正经典的热传导计算模型,可望有效地提高模拟过程的计算精度。结论为进一步研究薄板激光弯曲的变形机理及变形过程奠定了基础。

通过红外热像仪测温装置,对有限厚度试件在激光点热源作用下热作用区侧面温度分布进行实时测量。结果表明:对于小厚度的试件,材料内部温度分布与用傅立叶定律得到的结果完全相反,材料内部的温度高于边界温度。对比短脉冲激光作用下产生非傅立叶效应的条件,它们之间有很大差异,由此提出将实验中出现的非常规现象定义为泛傅立叶效应,认为它是由于热量传播到边界时发生反射、叠加等波动行为所致。
