Outside the Terrestrial Sphere Greg Lynn FORM: N.O.A.H. (New Outer Atmospheric Habitat) and New City

Renowned architect and educator Greg Lynn describes two projects - N.O.A.H, a science-fiction film, and New City, a design exhibit at the Museum of Modern Art (MoMA) in New York - that directly ‘engage the theme of Space Architecture as the new frontier for design research in terms of the spatial character and navigation of environments with alternative gravities’.     

华盛顿新建剧院

在上世纪的六七十年代,美国首都华盛顿特区也和目前国内的各大城市一样,经历了剧院建设的高潮,著名的肯尼迪艺术中心和中心舞台剧院1)都是那个时代的代表作,也成为华盛顿的城市地标.     

建筑与场地——贝聿铭的七个新作译介

以访谈的形式介绍了贝聿铭的7个新作,在这些作品中他以近代建筑设计为目标,同时十分重视各国本土文化的根,运用石头、混凝土、玻璃和钢筋等材料设计出划时代的建筑作品。在构思建筑时他对建筑场地的解读和处理表现出卓越的才智,将建筑和艺术的精髓作为永远的景观来构筑。表现了大师对场地的理解、材料的运用以及几何美学、光影美学的高度提炼,是把传统的建筑艺术与现代的先进技术融于一体的经典之作。     

PAH and metal mixtures in New Orleans soils and sediments.

The purpose of this study is to determine the degree of PAH contamination and the association of PAHs with inorganic substances in soils and sediments of New Orleans. Bonnet Carré Spillway (BCS) (n = 5) provides modern baseline data, while urban soil samples (CTY) (n = 27) and sediment samples from Bayou St. John (BSJ) (n = 11) provide experimental data for New Orleans. Soil samples were collected from the top 2.5 cm of the surface, air-dried, and sieved (2 mm). Sediments samples were collected with a Wildco-Ekman bottom dredge, air-dried and finely ground. Accelerated solvent extraction (ASE) was used to release PAHs from the samples and analysis was conducted with gas chromatography-mass spectrometry (GC-MS). Metals were extracted using a 5:1 ratio of 1 mol/L nitric acid (room temperature) for soil and sediment samples, shaken for 2 h, centrifuged (1000 x g for 15 min) and filtered. Metal analysis was done by inductively coupled plasma-atomic emission spectrometry (ICP-AES). Mann-Whitney tests show PAH differences (P < 0.001). Ranking of total PAHs is, BSJ sediments (10.3 mg/kg) > CTY soils (3.7 mg/kg) > BCS alluvium (0.28 mg/kg). The sum of the metals are similar for BSJ sediments (698 mg/kg) and CTY soils (679 mg/kg) and significantly lower for BCS (189 mg/kg). Manganese of these samples is similar for each site. For paired samples, Pearson Product Moment Correlation tests reveal that many PAHs are strongly associated with each other at all locations. For BCS alluvium and BSJ sediments, total PAHs are not significantly associated with total metals. For CTY, most pairs of metals are significantly associated, and total soil PAHs are strongly associated with total soil metals (correlation 0.78, P = 4.9 x 10(-4)). The linear model, total soil PAH = 136.3 + 6.25 (total soil metals) forms the basis for a predicted PAH map of New Orleans. Previous empirical research demonstrates an association between soil lead and children's lead exposure. This study indicates that PAHs are part of the soil mixture of accumulated substances and by-products of industrial society that presents exposure potential in cities.     

洛迦诺湖上的新住宅

这幢新住宅位于洛迦诺湖(Locamo)上,地理位置优越,可以俯瞰城市风光,周围的湖光山色也尽收眼底.这个项目是对日常生活中的林林总总的主题作了细致的研究,最终建筑师的定位是:在喧嚣拥挤的都市中创造出一个宁静居所,将传统房屋的属性完全忽略.
