There has been no precise information regarding occupants’ status and their portion in traffic accident. By using traffic police information, epidemiological pattern of road traffic injuries among occupants’ vehicles was analyzed in 2012. It was a cross sectional study. In this study, traffic police registered data in 2012 were used. Subjects were all occupants who had accident record in 2012 (81585: 77841 injured and 3744 death). Before analyzing, various preparatory steps including data control and merging were done after which data were processed. Findings showed that the mean age of the studied population was 28.7 ± 15.11 years. The highest percentage of accident occurred among car and motorcycle occupants respectively. The risk of death among the injured aged 30 - 59 years and 60+ were 1.20 and 2.23 times more than 30 years (as reference) respectively (p < 0.001). Risk of death among the injured in high ways, main roads and rural roads was 2.84 times more than in urban roads (p < 0.001). The risk of death among the injured was 2 times higher in high ways, main roads and rural secondary roads than streets (p < 0.001). Hence car and motorcycle occupants need urgent attention especially in motorways and high ways, main roads and rural secondary.

Surface modification of broom sorghum-based activated carbon via functionalization with triethylenetetramine and urea for CO2 capture enhancement

引用

Frontiers of Chemical Science and Engineering 2017年第2期11卷 252-265页

作者： elaheh Mehrvarz Ali A. Ghoreyshi Mohsen Jahanshahi Chemical Engineering Department Babol University of Technology Shariati Av. Babol Mazandaran 47148-71167 Iran

A new type of activated carbon （AC） was synthesized using broom sorghum stalk as a low cost carbon source through chemical activation with H3PO4 and KOH. The AC obtained by KOH had the largest BET surface area of 1619 m^2·g^-1 and the highest micropore volume of 0.671 cm^3·g^-1. CO2 adsorption was enhanced by functionalizing the AC with two different amines： triethylenetetramine （TETA） and urea. The structure of the prepared ACs was characterized by Brunauer-Emmett-Teller method, scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis and acid-base Boehm titration analyses. The adsorption behavior of CO2 onto raw and amine-functionalized ACs was investigated in the temperature range of 288-308 K and pressures up to 25 bar. The amount of CO2 uptake at 298 K and 1 bar achieved by AC-TETA and AC-urea was 3.22 and 2.33 mmol·g^-1 which shows a 92% and 40% improvement compared to pristine AC （1.66 mmol·g^-1）, respectively. Among different model isotherms used to describe the adsorption equilibria, Sips isotherm presented a perfect fit in all cases. Gas adsorption kinetic study revealed a fast kinetics of CO2 adsorption onto the ACs. The evaluation of the isosteric heat of adsorption demonstrated the exothermic nature of the CO2 adsorption onto unmodified and modified samples.

Selective separation of gallium from aluminum in SDS–Ga–Al and SDS–Ga–Al–fluoride systems by ion flotation

引用

Journal of Central South University 2017年第4期24卷 789-795页

作者： Bahri Zahra Rezai Bahram1 Kowsari elaheh Department of Mining and Metallurgical Engineering Amirkabir University of TechnologyTehran 158754413Iran Department of Chemistry Amirkabir University of TechnologyTehran 15916-34311Iran

Selective separation of gallium from aluminum by ion flotation using sodium dodecyl sulfate(SDS) as an anionic surfactant and fluoride as an inorganic ligand was investigated. The experimental results were analyzed using the stability constants and speciation diagrams of fluoride metal complexes. The presence of fluoride in the solution has a positive influence upon the separation of gallium from aluminum. The results show that increasing the fluoride concentration makes a more effective separation of gallium from aluminum because of a simultaneous increase in the complexion of aluminum with fluoride and a change in the electrical charge of the aluminum(ALF_4^-). The dehydration model of LIU and DOYLE was also applied to compare the ion flotation and the selectivity coefficients of gallium over aluminum with experimental results.

Comparative study of the factors affecting the generativity of office spaces

引用

Frontiers of Architectural Research 2019年第1期8卷 106-119页

作者： Maziar Asefi Farzin Haghparast elaheh Sharifi Faculty of Architecture and Urbanism Tabriz Islamic Art University Tabriz Iran

This study investigated the categories of generative and conservative offices by using syntactic theories and conducting a comparative analysis of two different layout con figurations. Gen erativity depends on several features that in elude but are not limited to spatial criteria. Generativity is also affected by aspects that extend beyond the physical, such as the symbolic relati on ship between the social orga nism of an orga nizati on and the in ternal structure of a workplace. Results show that no con sistent relati on ship exists between spatial variables and behaviors even though the examined layouts satisfy an organization's basic cultural requiremen ts, in cludi ng privacy, territoriality, and hierarchy. Spatial parameters in crease the potential for generativity, but such increase is not guaranteed without necessary changes in the attitudes, programs, and policies of organizations. Recognizing the limits of spatial variables requires evidence-based field research on office settings to determine operational and tailormade solutions.
