摘要：自从1991年以来，Chico’s连锁餐厅就一直向芬兰人民专供北美风味食品。到了2012年春，旗下老字号餐厅名为“大苹果餐厅（Iso Omena）”在经过大胆全新的室内设计后重新开业。Amerikkaa设计事务所为迎合餐厅新式食品、饮料和服务理念，特意为餐厅注入了全新的空间设计理念，重新设计后的餐厅在视觉上发生了蜕变。

摘要：拓扑节线半金属具有体能带反转形成的闭合环状狄拉克节线.体狄拉克节线投影到某些表面会形成闭合的圈,圈内会出现受拓扑保护的能量色散非常小的鼓膜状表面态,导致在费米能级具有高的电子密度.目前,为寻求贵金属铂的替代物,新的析氢反应催化剂需要具有高电子密度的催化活性位置,高的载流子移动性和恰当的热力学稳定性(ΔG≈0).由鉴于此,我们考虑具有稳定拓扑非平庸表面态的狄拉克节线半金属是否可以作为析氢催化的平台.基于第一性原理计算,我们提出TiSi型拓扑节线态半金属新家族.在其倒空间k_y=0面,反转的两条能带相交形成闭合的狄拉克节线环.氢吸附过程计算表明,拓扑狄拉克节线完整投影的(010)表面氢吸附自由能ΔG几乎为0.并且,拓扑电荷载流子也参与到了析氢过程.综上,我们提出拓扑狄拉克节线系统可以利用其鼓膜类拓扑表面态作为拓扑量子催化的平台,并认为TiSi家族材料有望成为析氢反应的催化剂,这种催化设计路线主要利用拓扑节线材料非平庸鼓膜类表面态作为催化活性位置,与以往传统通过缺陷、界面修饰和构筑等调控催化剂存在本质不同.

摘要：理念与建筑的互慕相成福州,是中国古代海上丝绸之路的起点之一,也是21世纪海上丝绸之路的战略支点城市。作为福州市的文化地标,海峡文化艺术中心必然将是一座肩负着文化传承与创新重任,并兼具地域性和国际性的中国建筑。以此作为本次设计的出发点,是中国、芬兰两国设计团队在设计之初就达成的高度共识。《茉莉花》是歌剧《图兰朵》中广为传唱的东方小调,并早已成为中国文化的代表符号之一。同时,茉莉花是福州市的市花,在西汉时期就已在福州被栽种,是福州文化的重要组成部分。可以说,茉莉花是中西文化的交汇点,是中国与世界相互连接的桥梁之一。由此,茉莉花这一自然天成的形象,成为中芬两国设计师的共同选择。

摘要：In this paper, the effect of the source of recycled coarse aggregate on the properties of concrete is investigated. The tests were conducted on concrete made from three sources of recycled aggregates: (1) old concrete with unknown strength, (2) old concrete with a known compressive strength of 21 MPa, and (3) old concrete with a known strength of 42 MPa. The three sources of recycled aggregates were used to produce new concrete with a target compressive strength of 21 MPa. The first and third sources of recycled aggregates were used in producing concrete with target strength of 42 MPa. A control mix was designed with aggregates from natural sources. The research included two methods of making recycled concrete. One concrete mix was produced using the recycled aggregate and adding more water than the control mix, to reach the target slump, while the second concrete mix was produced using the same amount of water as the control mix but with additional superplasticizer to maintain the target slump. The results obtained in this research showed that the concrete compressive strength depends on the source of recycled aggregates; the stronger the source of recycled aggregate, the higher the compressive strength of the produced concrete. Furthermore, the compressive strength of the first concrete mix was about 10%-20% lower than the compressive strength of the control mix. However, when superplasticizers were used, the compressive strength was around the same value as the control mix.

摘要：主要介绍了触发器的设计和性能。为了分析撞击型触发器的几何特征对于轴向冲击荷载作用下耗能构件的抗挤压性能的影响,对其进行数值分析。该耗能构件由一个平盖加一个帽形顶部剖面构成。将触发器视为一个在帽形剖面上具有半圆形横截面的突起物,采用有限元软件LS-DYNA模拟所有的挤压作用。结果显示:在挤压力峰值和轴向冲击荷载作用下的构件耗能能力上,触发器的引入非常有效。同时发现,通过改变触发器的位置和几何尺寸,可以控制构件的挤压响应。
