Membranes have attracted much attention as economical methods for industrial chemical processes. The effects of the titanium dioxide nanoparticle load on the morphology and CO2/CH4 separation performance of poly (ether-block-amide)(PEBAX-1657) mixed matrix membranes (MMMs) were investigated from pressures of 3-12 bar and temperatures of 30℃-60℃. The PEBAX membranes were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermal gravimetric analysis, atomic force microscopy and tensile strength analysis. The incorporation of TiO2 nanoparticles into the polymeric MMMs improved the CO2/CH4 gas separation performance (both the permeability and selectivity) of the membranes. The CO2 permeability and ideal CO2/CH4 selectivity values of the nanocomposite membrane loaded with 8 wt-% TiO2 were 172.32 Barrer and 24.79, respectively whereas those of the neat membrane were 129.87 Barrer and 21.39, respectively.

This paper discusses the calculation of plastic zone properties around circular tunnels to rock-masses that satisfy the Hoek–Brown failure criterion in non-hydrostatic condition,and reviews the calculation of plastic zone and displacement,and the basis of the convergence–confinement method in hydrostatic condition.A two-dimensional numerical simulation model was developed to gain understanding of the plastic zone *** zone radius in any angles around the tunnel is analyzed and measured,using different values of overburden(four states)and stress ratio(nine states).Plastic zone radius equations were obtained from fitting curve to data which are dependent on the values of stress ratio,angle and plastic zone radius in hydrostatic *** validation of this equation indicate that results predict the real plastic zone radius appropriately.

Effects of vernacular architecture structure on urban sustainability case study： Qeshm Island, Iran

引用

Frontiers of Architectural Research 2018年第1期7卷 11-24页

作者： Hamed mohammadi Mazraeh Mahdieh Pazhouhanfar Department of Architecture Bandar Abbas Branch Islamic Azad University Bandar Abbas Iran Department of Architecture Faculty of Engineering Golestan University Gorgan Golestan Iran

The architecture of Qeshm Island includes the specific architectural style of a warm and wet area, which previously had a functional use aimed to reach a sustainable architecture and development. However, few studies on the identification of the characteristics of vernacular architecture and their roles in island stability have been performed. Thus, to understand the vernacular architecture of the island as a sustainable pattern, we discussed it separately in three aspects, namely, urban fabric, one-based architecture, and architectural details. To address our study, a part of the old fabric of the city with its existing buildings （42 buildings of 70 years of age） was selected and evaluated in a qualitative study. Results showed that in the scale of the urban fabric, factors, such as the structures of the buildings, the frame of the neighborhood spaces, and in terms of the architectural details, factors, such as bars, thickness of the watts, and the openings, are among the vernacular features of the area, playing an important rote in the stability of Qeshm Island. In general, studies showed that vernacular architecture of the island has focused on developing an orientation between the climate of the region and a good understanding of the construction.
