This study presents findings of indoor environmental quality （IEQ） investigations conducted in elementary schools＇ classrooms in the United Arab Emirates （UAE）. Average TVOC, CO2, O3, CO, and particle concentrations measured in the classrooms were 815 pg / m^3, 1605 ppm, 0.05 ppm, 1.16 ppm, and 1730 μg/m^3, respectively. Whereas, local authority known as Dubai municipality recommended 300 pg/m^3, 800 ppm, 0.06 ppm, 9 ppm, and 150-300 μg/m^3 for TVOC, CO2, O3, CO, and particle, respectively. Dubai municipality recommended temperature and retative humidity （RH） levels of 22.5 ℃ to 25.5 ℃ and 30%-60%, respectively. Average temperature and RH levels measured in the classrooms were 24.5 ℃ and 40.4%, respectively. Average sound level in the classrooms was 24 dB greater than recommended sound level limit of 35 dB. Six （6） classrooms had average lux levels in the range of 400-800 lux. Two （2） classrooms had average lux levels in the range of 100 200 lux. The remaining classrooms had lux levels around the recommended 300 lux. High occupancy density was observed in majority of the studied classrooms.

多尺度旋涡现象广泛地存在于工程领域的湍流中.研究湍流的重要方法是大涡模拟,但大涡模拟中的过度耗散问题是曲面边界、多尺度旋涡模拟所面临的主要困难.为了克服过度耗散的缺陷,使大曲率曲面边界的多尺度涡流脉动特性预报更准确,文章采用正则化变分多尺度模型(RVm)改进了壁面自适应涡黏模型(WalE)中的亚格子模型,并采用C++语言在Open FOAm开源平台实现了计算代码编译.文章以经典圆柱黏性绕流作为曲面边界黏性绕流的代表,讨论了改进的大涡模型(m.alE)中滤波算子对亚临界雷诺数(Re=4.0×10^(4))波算子阶数(n)敏感.四阶滤波算子(n=2)能准确地预报圆柱壁面的平均涡量及尾流瞬时涡量分布、再循环旋涡长度和速度剖面,而二阶滤波算子(n=1)无法准确地预测分离区和尾流区内脉动速度剖面,因此在强压力梯度区四阶滤波算子预测的压力分布、脉动升阻力与实验结果吻合的更好,能更准确地捕捉到多尺度旋涡结构.

Wittig reactions of benzaldehydes, alkanals, and cycloalkanals as well as of acetophenones are carried out with alkoxycarbonyl methylidenetriphenylphosphoranes in 10 w% aqueous NaOH, where the cinnamates and alkenoates produced are hydrolysed in situ and the corresponding acids are obtained after mostly simple extractive work-up, often without employing organic solvents. Under the same conditions, benzaldehydes are reacted with alkoxycarbonyl bromomethy-lidenephosphorane to produce 3-arylprop-2-ynoic acids (arylpropiolic acids).

Large deposits of impure kaolins exist in Jordan and many parts of the world;geoplymers can reduce environmental impacts and have multi-application in many fields, such as water purification, waste treatment, fire proof construction, etc. The aim of this research is to investigate the use of alkali activated zeolitic tuff and low purity metakaolin as precursors for the production of functional geoplymers exhibiting proper mechanical properties and high potential for water storage and decontamination of polluted solutions. The results confirmed that this type of geopolymers showed superior mechanical characteristics and higher adsorption capacity towards heavy metals such as Cu(II) ions, which was similar to natural zeolite. X-ray diffraction analysis showed that phillipsite, a major zeolite mineral, disappeared upon geopolymerization, while scanning electron microscopy analysis showed that geopolymers exhibit a porous matrix of nano-particles. The geopolymers have also displayed high compressive strength and tensile bending strength of about 7.8 mPa and 45 mPa respectively, compared to reference geopolymers. This functional-geopolymers indicate that they are efficient, cost effective and have a potential for number of applications including construction, water storage and wastewater treatment.
