Levels of antimony,arsenic, cadmium,copper, lead,mercury, selenium,silver, tin and zinc in bone tissue of industrially exposed workers

The contents of the elements antimony, arsenic, cadmium, copper, lead, mercury, selenium, silver, tin and zinc in bone tissue from autopsy specimens of the femur of workers who had been exposed to a large number of metals in a smeltery and refinery in Northern Sweden as well as of a control group have been quantitatively assayed.The analytical techniques used were atomic absorption spectrophotometry, neutron activation analysis and particle induced X-ray emission analysis (PIXE) in a proton microprobe. Increased levels of lead in the bone tissue of exposed workers compared to a non-exposed control group were observed. The median level of lead in the group of exposed workers exceeded the corresponding value of the control group about 5 times.Using the proton microprobe in the PIXE-mode, concentration profiles of copper, lead and zinc were examined within the Haversian system of the bone samples.     

高黎贡手工造纸博物馆，云南，中国

纸张产生于迄今2000多年前,是中国古代四大发明之一。顾名思义,手工造纸博物馆展现了造纸的历史与过程,辅以现场演示和手工作坊的阐释手段。它展示、保存和开发当地的造纸艺术,并推动该领域的学术研究和文化交流。为了实现这些目标,博物馆为来访者提供了住宿和艺术家的住宅,并设计了一间茶室作为当地人的聚会活动场所。它可以视作中国近期发展小规模专业博物馆趋势的一部分。这些专业博物馆致力于记录和宣传中国的地区历史与文化。     

纳高尔堡修缮，纳高尔，拉贾斯坦，印度

拉贾斯坦邦中部的古城纳高尔是印度北部的穆斯林势力（12—16世纪）的第一批据点之一。纳高尔位于一条重要的马帮路线上,这里也是苏菲派重要的修行和朝圣中心。纳高尔堡坐落在一座小山上。     

长生殿昆曲舞台,上海,中国

<正>戴志康邀请著名昆曲演员张军先生在会所表演昆曲经典戏目——长生殿。建筑师通过仔细研究会所,决定利用开放的下沉庭院,并尽量不改动现状来建设小剧院。他将中国古代在庭院临时分割空间的屏风这个概念,转换可以展现灯光图像的屏幕把整个庭院精致地隔离成一个抽象、纯粹、白色的场所。以最现代的形象表     

清华大学建筑学院新馆,北京,中国

<正>新建筑馆的体量为旧馆内院的三边所限定。为了模糊表面之间的距离以消解位处夹缝中的压迫感,立面铺满倾斜的穿孔钢板。建筑下沉地面半层,底层架空并采用玻璃立面,东西两面向内退2m,以进一步获得轻盈感,减少对地面的压迫。立面划分为九宫格,并进一步由钢板均质划分,与无序的室外环境对比、相衬。新建筑不对旧立面做形态上     

Determination of Co,Cu, Fe,Hg, Mn,Sb, Se and Zn in milk samples

Concentrations of Co, Cu, Fe, Hg, Mn, Sb, Se and Zn in IAEA milk (dry) standard A-11 were re-evaluated with the help of instrumental and radiochemical neutron activation analysis (NAA). The results show reasonably good agreement for Co (5.1 ± 0.55 ng/g) and Zn (34 ± 2.5 μg/g), in relation to the recommended values. For Cu (374 ± 15 ng/g), Fe (2.4 ± 0.34 μg/g) and Mn (250 ± 20 ng/g); the results obtained are lower than the reported values.Cu, Mn, and Zn were cross-checked by atomic absorption spectrophotometry (AAS). The results, Cu = 331 ± 27 ng/g, Mn = 302 ± 62 ng/g, and Zn = 35 ± 1 μg/g, fall within the range of mean values obtained by NAA.For Hg and Se, using instrumental NAA, only upper limits could be indicated; because of the low levels of concentrations of Hg and Se on one hand, and high content of P (9100 μg/g) in A-11 milk standard on the other, NAA coupled with radiochemistry is to be preferred for these two elements.In pooled human milk, in addition to Cu and Mn (radiochemical) and Co, Fe, Sb and Zn (instrumental), Hg and Se could also be determined non-destructively because of the favourable Hg/P and Se/P ratios in this matrix.     

Archi-Union Architects,City of Breeze,Shenzhen Bay,Shenzhen, China

What happens when ancient cultural practices are combined with the most current design technologies? Archi-Union Architects used the opportunity of their entry to the 2014 Shenzhen Bay ‘Super City’ International Competition to develop a bespoke generational method that integrated feng shui with advanced environmental simulation techniques. Philip F Yuan, the founder and director of Archi-Union Architects, who is Associate Professor in Architecture at Tongji University, Shanghai, here describes the City of Breeze project and the design methodology behind it.     

波士顿艺术博物馆,波士顿,美国

波士顿艺术博物馆成立于1870年,是美国最大、世界上最好的博物馆之一,每年有超过100万的参观者。但是,同其他许多此类机构一样,观众的规模导致了博物馆设施被过度使用。在建筑上,这个项目重复了德国议会大厦和大英博物馆的大厅所探讨的主题,结合了新旧元素,并且通过让博物馆变得更为开放和易达来加强同社区的联系。博物馆总体设计的核心是对建筑的鲍扎平面的逻     

大不里士集市复兴，大不里士，伊朗

大不里士集市于1975年正式得到保护并在特殊监管下运营。2010年,它被收录到世界遗产名录中。集市占地27hm^2,长度超过5．5km.到了20世纪后期,其中的砖房由于年久失修开始摇摇欲坠,为此人们建立起了由“集市”社区、市政府和文化遗产手工业及旅游组织（ICHTO）一起参加的管理框架。试点的修复项目首先获得了店主们的支持,也让后续的整体修复项目能达到保护和振兴集市这一宝贵遗产的目的。在试点项目中,政府出资85％,“集市商户”仅出资修复成本的15％,但目前集市社区已经负担了修缮基金中90％的费用。     

威斯特道斯传播学院,奥斯陆,挪威

<正>该建筑位于奥斯陆的一个老工业区"Vulkan"中,该区域毗邻风景如画的阿克斯河和库巴时尚公共空间。设计的构思源于一个"格格相扣"的想法,建筑的体量比地基的轮廓范围小,设计师在沿着建筑地面层的外沿设计了一条玻璃光带,从而创造出一个富于变化的地下空间。白天,地下空间汲取着日光的能量,夜晚,光线又会由此透射出来,就仿佛在建筑自己的空间内创造了一个"自发光体"。
