联接复合体——霍尔的马赛公寓

文章是基于现当代城市／建筑文化对斯蒂文霍尔在北京的联接复合体与勒柯布西耶的马赛公寓的对比分析,不是为了印证某种历史的巧合或进行某种类比,而是为了激发和揭示霍尔这个重要作品的某些尚未被发掘的特质。     

雷德朋体系的道路交通规划思想评述

雷德朋作为汽车时代第一域,其道路交通规划思想曾被认为是现代依赖小汽车的土地开发模式的先驱。通过对雷德朋体系规划思想的历史追溯,回顾了其规划思想产生的背景,提出的规划目标和对应的规划方法,在此基础上对规划思想的整体性优点进行了分析,在总结其提出的分级道路系统和人车分流体系特点的同时也指出其历史局限性,并根据上述分析重新评价了雷德朋体系合理的历史定位。为当前发展以公共交通为导向和强调多种交通模式相融合的道路交通规划新思想提供借鉴。     

Surviving Versus Living: Nature and Nurture

Today so many aspects of our everyday lives are dependent on nature, yet remain removed from it. Here, two speculative projects by the architect May Leung explore how nature can nurture in ways that space cannot, by creating self-sustainable systems to change the way that we think about production, consumption, leisure and the routine of our working lives.

Evaluation of adult and offspring thiamine deficiency in salmonine species from Lake Ontario

Thiamine Deficiency Complex (TDC) is an ongoing problem impacting salmonine health in various waterbodies, including Lake Ontario. The prevalence of TDC has been variable and explanations for differences are limited. In the current study, thiamine concentrations were measured in eggs, liver tissue, and muscle tissue sampled from brown trout (Salmo trutta), Chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), lake trout (Salvelinus namaycush), and steelhead trout (O. mykiss) that were collected from Lake Ontario and its surrounding tributaries. The occurrence of TDC was measured for each species based on TDC-induced offspring mortality rates under laboratory conditions. TDC-induced offspring mortality was observed for all species except brown trout. For affected species, egg free thiamine (Th) was consistently low compared to lake trout collected from Lake Superior that are considered thiamine replete. In addition, species with the lowest percentages of Th in their eggs were the most susceptible to TDC, suggesting that limited thiamine reserves in the form of Th may cause TDC-induced offspring mortality. Lastly, our results show that egg thiamine concentrations have yearly variation and increased for all species throughout the study. Reasons for such variation are undetermined; but, if egg thiamine concentrations continue to increase, the impacts of TDC on these salmonine species may lessen. Future monitoring is needed for determining if thiamine concentrations are increasing and the potential impacts that may have on the entire Lake Ontario fishery.     

哈尔滨典型街谷空间PM2.5分布场与绿色界面指数相关性 研究

在城市化快速进程的背景下，城市 街区PM2.5污染日益严重，本文选取哈尔滨 在不同季节的典型街谷空间，对以叶面积密 度（LA D）、叶面积指数（LAI）为实测要素 的绿色界面指数以及PM2.5浓度进行实测对 比研究。通过对实测数据的分析和挖掘，最 终得出如下结论：首先，典型街谷空间PM2.5 时段浓度呈现上午比下午平均高37.75%，冬 季比夏季高4.7倍的特征；其次，街谷空间的 灌木界面对PM2.5浓度场平均积极贡献率为 18.62%；最后，对PM2.5的衰减率与实测街 谷绿色界面的叶面积密度（LAD）与叶面积 指数（LAI）进行相关性分析，结果显示街谷 绿色界面对PM2.5浓度的衰减作用与叶面积 密度（LAD）呈显著负相关关系，与叶面积指 数（LAI）的相关性程度较弱。
