| 1 | Trend analysis and comparison of basic parameters for tunnel blast design models显示文摘One of the most important factors influencing on a tunnel blast efficiency is the proper design of blasting pattern. Among blasting parameters, blasthole diameter and tunnel face area are more significant so that any change in these parameters could finally affect on specific charge and specific drilling. There are mainly two groups of methods for tunnel blast design categorized based on the parallel cuts and angular cuts. In this research, a software for tunnel blast design was developed to analyze the effect and sensitiveness of blasthole diameter and the tunnel face area on blasting results in different blast design models. Using the software, it is quickly possible to determine specific charge, specific drilling and number of blastholes for each blast design model. The relations between both of blasthole diameters and the tunnel face area with the above parameters in different blast design models were then investigated to yield a set of equations with the highest correlations to compare the methods. The results showed that angular method requires more blasthole numbers than parallel method in similar condition(blasthole diameter and tunnel face area). Moreover, the specific charge values yielded by the two methods are approximately the same and very close together. | Khalili Soroush Yavary Mehdi Ebrahimabadi Arash | 2015 | International Journal of Mining Science and Technology2015,25,4: | 7 |

| 4 | Prevalence survey of infection with Treponema pallidum among HIV-positive patients in Tehran显示文摘Objective:To identify the frequency of syphilis among Iranian HIV-positive patients.Methods:A cross-sectional study on the prevalence of syphilis and HIV co-infection among 450 patients diagnosed with HIV infection was conducted between 2004 and 2008 at Imam Khomeini hospital,Tehran,Iran.The lab tests including CD4 cell count,cerebrospinal fluid,veneral disease research laboratory(VDRL),fluorescent treponema antibody-absorption(FTA-Abs)and viral load were performed for all the patients.Data regarding medical history and their demographics were also collected.Results:Of all 450 HIV-positive patients,24(5.3%)had a positive VDRL test and only two men had a FTA-Abs positive test which means 0.45%of them had a definite co-infection of syphilis.65.3%of the HIV-positive patients were injection drug users that the co-infection prevalence of them was 0.7%.We did not find any patient with neurosyphilis.Conclusions:Considering the increasing prevalence of HIV and also extensive use of highly active antiretroviral therapy in developing nations,the diagnosis of syphilis should be timely established using screening tests among such patients. | Banafsheh Moradmand Badie Zeinab Yavari Shooka Esmaeeli Koosha Paydary Sahra Emamzadeh-Fard SeyedAhmad SeyedAlinaghi Mehrnaz Rasoulinejad | 2013 | Asian Pacific Journal of Tropical Biomedicine2013,3,4: | 3 |
| 5 | Landau damping in a dipolar Bose–Fermi mixture in the Bose–Einstein condensation(BEC) limit显示文摘By using a mean-field approximation which describes the coupled oscillations of condensate and noncondensate atoms in the collisionless regime, Landau damping in a dilute dipolar Bose–Fermi mixture in the BEC limit where Fermi superfluid is treated as tightly bounded molecules, is investigated. In the case of a uniform quasi-two-dimensional(2D)case, the results for the Landau damping due to the Bose–Fermi interaction are obtained at low and high temperatures. It is shown that at low temperatures, the Landau damping rate is exponentially suppressed. By increasing the strength of dipolar interaction, and the energy of boson quasiparticles, Landau damping is suppressed over a broader temperature range. | S M Moniri H Yavari E Darsheshdar | 2016 | Chinese Physics B2016,25,12: | 3 |

| 8 | Biodegradation of natural and synthetic estrogens in moving bed bioreactor显示文摘Estrogen hormones as a group of endocrine disruptive compounds(EDC) can interfere with endocrine system in humans and animals. The goal of this study was to investigate the elimination rate of Estrone(El), 17β-estradiol(E2) and 17α-ethinyl estradiol(EE2) in Moving Bed Bioreactor(MBBR). These analytes extracted by Dispersive Liquid-Liquid Microextraction(DLLME) technique, followed by derivatization, and detected by GC/MS. Estrogen removal efficiency in MBBR improved at high solid retention times(SRTs), which notion is owing to development of nitrification. Estrogen specific removal rate was between 0.22-1.45 μg·(g VSS)^(-1)·d^(-1) for natural and synthetic hormones. The adsorption rate was 0.9%-3.2%, 0-1.3%, and 0.7%-5.7% for El, E2, and EE2, respectively. In addition, the biodegradation rates were more than 95% for these compounds. These results illustrated that in MBBR,the biodegradation and the adsorption to biomass are considered as two significant routes for elimination of estrogenic compounds. As a whole, the deterioration rate of estrogens enhanced by MBBR compared to other biological wastewater treatment processes such as conventional activated sludge. | Mohammad Mehdi Amin Bijan Bina Karim Ebrahim Zeynab Yavari Farzaneh Mohammadi | 2018 | Chinese Journal of Chemical Engineering2018,26,2: | 2 |

| 15 | Evaluation of the effects of Alkyl Phenolic compounds on kinetic coefficients and biomass activity in MBBR by means of respirometric techniques显示文摘The presence of Alkyl Phenols(APs) in aquatic systems is considered as one of the environmental concerns in recent decades which are generally used as surfactants. APs are endocrine disruptors and estrogen-mimicking,causing harmful effects such as feminization and carcinogenesis on aquatic environment and human health.The most commercially important APs are 4-Nonyl Phenol(4-NP) and 4-tert-OctylP henol(4-t-OP). Moving bed biofilm reactor(MBBR), which combined attached and suspended growth advantages, is an advanced biological treatment process for municipal and industrial wastewaters that has drawn considerable attention from many researchers to remove toxic pollutants from wastewater. The aim of this research was to evaluate Bacterial activities and kinetic coefficients in the presence of APs. This study was carried out using laboratory-scale MBBR fed with synthetic wastewater containing 4-NP and 4-t-OP. The reactor was operated at different loads of chemical oxygen demand(COD) and APs and different hydraulic retention time(HRT). The respirometric technique was applied to investigate the effect of APs on heterotrophic and autotrophic activity and kinetic coefficients in biomass obtained from MBBR. Respirometric technique demonstrates a reliable tool in order to assess the biofilm kinetic coefficients and biomass viability to insert in the mathematical models. The calculated kinetic parameters were in the range of conventional and extended aeration activated sludge processes. The results demonstrate that APs have significant inhibitory effects on activity and growth rate of heterotrophic and autotrophic bacteria, heterotrophs have been less affected by the presence of 4-NP and 4-t-OP, and these compounds had greater inhibitory effects on autotrophic bacteria. | Bijan Bina Farzaneh Mohammadi Mohammad Mehdi Amin Hamid Reza Pourzamani Zeynab Yavari | 2018 | Chinese Journal of Chemical Engineering2018,26,4: | 1 |
