| 1 | Influence of the roughness and shape of quartz particles on their flotation kinetics显示文摘Surface roughness and shape play an important role on the behavior of particles in various processes such as flotation. In this re-search, the influence of different grinding methods on the surface roughness and shape characteristics of quartz particles as well as the effect of these parameters on the flotation of the particles was investigated. The surface roughness of the particles was determined by measuring their specific surface area via the gas adsorption method. The shape characteristics of the particles were measured and calculated by images obtained by scanning electron microscopy via an image analysis system. The flotation kinetics was determined using a laboratory flotation cell. The results showed that the particles of rod mill products have higher roughness and elongation ratio and lower roundness than the parti-cles of ball mill products. The flotation kinetics constant of the particles increased with their surface roughness increasing. Particles with higher elongation and lower roundness indicated higher floatability. In addition, the influence of the surface roughness on the flotation kinet-ics was greater than that of shape parameters. | Mehdi Rahimi Fahimeh Dehghani Bahram Rezai Mohammad Reza Aslani | 2012 | International Journal of Minerals,Metallurgy and Materials2012，19，4： | 8 |
| 2 | Persistent alanine aminotransferase elevation among the general Iranian population: Prevalence and causes显示文摘AIM: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran. METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was ≥ 40 U/L, it was rechecked twice within 6 mo. Those with ≥ 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran. | Raika Jamali Mahmoodreza Khonsari Shahin Merat Masoud Khoshnia Elham Jafari Alireza Bahram Kalhori Hassan Abolghasemi Sedighe Amini Mahtab Maghsoudlu Mohammad Reza Deyhim Houri Rezvan Akram Pourshams | 2008 | World Journal of Gastroenterology2008，14，18： | 7 |
| 3 | High-level classification of the Fungi and a tool for evolutionary ecological analyses显示文摘High-throughput sequencing studies generate vast amounts of taxonomic data.Evolutionary ecological hypotheses of the recovered taxa and Species Hypotheses are difficult to test due to problems with alignments and the lack of a phylogenetic backbone.We propose an updated phylum-and class-level fungal classification accounting for monophyly and divergence time so that the main taxonomic ranks are more informative.Based on phylogenies and divergence time estimates,we adopt phylum rank to Aphelidiomycota,Basidiobolomycota,Calcarisporiellomycota,Glomeromycota,Entomophthoromycota,Entorrhizomycota,Kickxellomycota,Monoblepharomycota,Mortierellomycota and Olpidiomycota.We accept nine subkingdoms to accommodate these 18 phyla.We consider the kingdom Nucleariae(phyla Nuclearida and Fonticulida)as a sister group to the Fungi.We also introduce a perl script and a newick-formatted classification backbone for assigning Species Hypotheses into a hierarchical taxonomic framework,using this or any other classification system.We provide an example of testing evolutionary ecological hypotheses based on a global soil fungal data set. | Leho Tedersoo Santiago Sanchez-Ramırez Urmas Koljalg Mohammad Bahram Markus Doring Dmitry Schigel Tom May Martin Ryberg Kessy Abarenkov | 2018 | Fungal Diversity2018，，3： | 7 |

| 5 | Higher order aberration comparison between two aspherical intraocular lenses: MC6125AS and Akreos advanced optics显示文摘AIM: To compare higher order aberrations in two aspherical intraocular lenses(IOLs): Akreos advanced optics(AO) and Dr. Schmidt Microcrystalline 6125 aspheric anterior surface(MC6125AS) with each other. METHODS: Forty eyes of 39 patients underwent phacoemulsification and Akreos AO and MC6125 AS were implanted in their eyes in a random manner. Three months post-operatively, higher order aberrations including spherical aberration, coma aberration, and total aberrations were measured and compared.RESULTS: The total aberration was 0.24±0.17 in eyes with Dr. Schmidt and 0.20 ±0.01 in eyes with Akreos AO(P =0.361). The mean of coma aberration was 0.17 ±0.21 and 0.09 ±0.86 in Dr. Schmidt and Akreos lenses,respectively(P =0.825). Total spherical aberration was almost the same in both groups(mean: 0.05, P =0.933).Best corrected visual acuity in Akreos AO(0.10±0.68) and Dr. Schmidt(0.09±0.67) did not differ significantly(P =0.700). CONCLUSION: There is no statistically significant difference in the higher order aberrations between these two aspherical lenses. | Mohammad Taher Rajabi Sara Korouji Mahgol Farjadnia Mohammad Naderan Mohammad Bagher Rajabi Bahram Khosravi Seyed Mehdi Tabatabaie | 2015 | International Journal of Ophthalmology(English edition)2015，8，3： | 5 |
| 6 | 先天性上睑下垂患者100例弱视致病原因的探讨(英文)显示文摘目的:评估先天性上睑下垂患者的弱视发病情况。方法:在本横断面研究中,包括1岁以上的先天性上睑下垂患者100例(114眼)。最佳矫正视力小于10/10或两眼之间至少相差2/10者定义为弱视。年幼患者不能进行斯内伦视力表检测者,观察其注视情况。不同弱视患者的类型:1)屈光参差性弱视:散光性屈光参差≥1.00D;远视性球镜屈光参差≥1.00D,近视性球镜屈光参差≥-3.00D(睫状肌麻痹);2)斜视性弱视,3)形觉剥夺性弱视(SDA)。观察弱视的总发病率及类型,并对单侧和双侧上睑下垂患者进行比较。结果:弱视的发生率在上睑下垂患者为39/114(34.2%),其具体原因:屈光参差性弱视占29.8%,SDA占10.5%,斜视性弱视4.3%,严重的上睑下垂患者弱视发病率更高,视轴遮盖者(OA)占76%,而视轴未遮盖者只占22%。在视轴遮盖的单侧眼睑下垂患者,散光屈光参差性弱视发生率更高,在双侧眼睑下垂至少1眼视轴遮盖者,球镜屈光参差性弱视发生率更高。无论单侧和双侧上睑下垂,如果有视轴遮盖,则SDA比较多见。结论:由于屈光参差性弱视比SDA发生率更高,关注导致的弱视所有原因对于预防儿童上睑下垂所致的弱视极其重要。 | Abolfazl Kasaee Alireza Yazdani-Abyaneh Syed Ziaeddin Tabatabaie Alireza K.Jafari Ahmad Ameri Bahram Eshraghi Vafa Samarai Meysam Mireshghi Mohammad Taher Rajabi | 2011 | 国际眼科杂志2011，11，3： | 4 |
| 7 | Numerical simulation of high voltage electric pulse comminution of phosphate ore显示文摘Numerical simulation of the electrical field distribution helps in-depth understanding of the mechanisms behind the responses and the benefits of the high voltage pulse comminution. The COMSOL Multiphysics package was used to numerically simulate the effect of ore compositions in this study. Regarding phosphate ore particles shape and composition, the effects of mineral composition, particle size, particle shape and electrodes distance were investigated on the electrical field intensity and distribution. The results show that the induced electrical field is significantly dependent on the electrical properties of minerals,the feed particle size and the location of conductive minerals in ores. The angle of material contact surface with the discharge electrode is also an important factor in the intensity of electrical field. Moreover,it is found that the specific liberation effect at the disintegration of phosphate ore by electrical pulses is due to the locality of the electrical field at the interface of mineral components of the phosphate ore aggregates with different permittivities. However, the intensity of the electrical field increases with sharpening the contact angle. Besides, the electrical discharge in the samples is converted to the electrohydraulic discharge across the surrounding water by changing the distance between the discharge electrode and sample surface. | Razavian Seyed Mohammad Rezai Bahram Irannajad Mehdi Ravanji Mohammad Hasan | 2015 | International Journal of Mining Science and Technology2015，25，3： | 4 |

| 9 | Microstructure and Impression Creep Properties of Ca-Containing AS31 Magnesium Alloy显示文摘The effect of Ca addition on the microstructure and impression creep properties of AS31 magnesium alloy was investigated in the current study.The results showed that the microstructure of AS31 alloy is composed of α(Mg) phase,massive Mg_(17)Al_(12) and some Chinese script Mg_2Si compounds.Addition of 2 wt%Ca to AS31 alloy resulted in complete elimination of Mg_(17)Al_(12) phase and formation of Al_2Ca compound.Ca improved the alloy's creep properties especially at higher temperature.Improvement in the creep properties was attributed to the elimination of soft Mg_(17)Al_(12) and formation of thermally stable Al_2Ca compound.According to the obtained stress exponent and creep activation energy,pipe diffusion climb-controlled creep was estimated as the dominant creep mechanism and Ca had no influence on the dominant mechanism. | Mohammad Badri Seyyed Mehdi Miresmaeili Bahram Nami | 2016 | Acta Metallurgica Sinica(English Letters)2016，29，12： | 2 |

| 11 | Combination of sensitivity and uncertainty analyses for sediment transport modeling in sewer pipes显示文摘Mitigation of sediment deposition in lined open channels is an essential issue in hydraulic engineering practice.Hence,the limiting velocity should be determined to keep the channel bottom clean from sediment deposits.Recently,sediment transport modeling using various artificial intelligence(AI)techniques has attracted the interest of many researchers.The current integrated study highlights unique insight for modeling of sediment transport in sewer and urban drainage systems.A novel methodology based on the combination of sensitivity and uncertainty analyses with a machine learning technique is proposed as a tool for selection of the best input combination for modeling process at non-deposition conditions of sediment transport.Utilizing one to seven dimensionless parameters,127 models are developed in the current study.In order to evaluate the different parameter combinations and select the training and testing data,four strategies are considered.Considering the densimetric Froude number(Fr)as the dependent parameter,a model with independent parameters of volumetric sediment concentration(CV)and relative particle size(d/R)gave the best results with a mean absolute relative error(MARE)of 0.1 and a root means square error(RMSE)of 0.67.Uncertainty analysis is applied with a machine learning technique to investigate the credibility of the proposed methods.The percentage of the observed sample data bracketed by 95%predicted uncertainty bound(95PPU)is computed to assess the uncertainty of the best models. | Isa Ebtehaj Hossein Bonakdari Mir Jafar Sadegh Safari Bahram Gharabaghi Amir Hossein Zaji Hossien Riahi Madavar Zohreh Sheikh Khozani Mohammad Sadegh Es-haghi Aydin Shishegaran Ali Danandeh Mehr | 2020 | International Journal of Sediment Research2020，35，2： | 2 |

| 13 | The Use of Fractal for Prediction of Burning Rate of Composite Solid Propellants显示文摘By using the fractal geometry it is possible to calculate the actual AP (Ammonium Perchlorate) surface area and oxidizer-binder interface fractal dimension in the prediction of burning rate of composite solid propellants. In this investigation, the fractal dimension was determined by a procedure known as the 'Box Counting Method'. Using this dimension, surface area relations were developed for the rough particles. This method was implemented in the PEM (Petite Ensemble Model) burning rate model. The comparison of burning rates for a typical propellant by the PEM and fractal model shows that the burning rates obtained by using the fractal geometry are slightly less than those obtained by the PEM model. | Manouchehr Nikazar,Mohammad B.

| 14 | Warped time lens in temporal imaging for optical real-time data compression显示文摘We introduce for the first time the concept of anamorphic temporal imaging and its application to analog data compression in a time lens.Placed in front of a conventional spectrometer,this technique enhances the spectral resolution and the update rate.More importantly,it performs real-time optical data compression to reduce the volume of the generated digital data.Our technique introduces the concept of the warped time lens.We show that a specific class of warped time-to-frequency mapping operations combined with the nonlinear operation inherent in a photo-detector compresses the time-bandwidth product in a temporal imaging system.We employ our newly introduced Stretched Modulation Distribution to design the warp profile.Using this method,the narrow spectral features beyond the spectrometer resolution can be captured and at the same time the output bandwidth and hence the record length is minimized.The reduction in the record length results in higher update rate for the spectrometer without sacrificing the spectral resolution or bandwidth.Our method also benefits from amplitude and phase detection to recover the input complex-field spectrum.By compressing the time-bandwidth product,anamorphictemporal imaging addresses the Big Data problem in such high-throughput instruments. | Mohammad H.Asghari Bahram Jalali | 2014 | Chinese Science Bulletin2014，59，22： | 2 |
| 15 | Hydrocarbon Vertical Continuity Evaluation in the Cretaceous Reservoirs of Azadegan Oilfield, Southwest of Iran: Implications for Reservoir Geochemistry显示文摘A collection of data obtained from analytical methods in geochemistry along with the reservoir engineering and geologic data were used to investigate the reservoir continuity in the Cretaceous Fahliyan, Gadavan, Kazhdumi and Sarvak reservoirs of the super-giant Azadegan oilfield, SW Iran. The geochemical data indicate that the oil samples, with medium to high level of thermal maturity, have been generated from the anoxic marine marl/carbonate source rock(s). The Sargelu(Jurassic) and Garau(Cretaceous) formations are introduced as the main source rocks for the studied oils. The dendrogram obtained from the cluster analysis of high-resolution gas chromatography data introduces two main oil groups including Fahliyan reservoir, and Kazhdumi along with Sarvak/Gadvan reservoirs. This is confirmed by C7 Halpern star diagram, indicating that, the light oil fraction from Fahliyan reservoir is distinct from the others. Also, different pressure gradient of the Fahliyan Formation(over-pressured) relative to other reservoirs(normally-pressured) show the presence of compartments. The relation between toluene/n-heptane and n-heptane/methylcyclohexane represents the compartmentalization due to maturation/evaporative fractionation for Fahliyan and water washing for other studied reservoirs. Also, the impermeable upper part of the Fahliyan Formation and thin interbedded shaly layers in the Kazhdumi, Sarvak and Gadvan formations have controlled reservoir compartmentalization. | Bahram ALIZADEH Mehrab RASHIDI Alireza ZARASVANDI Seyed Rasoul SEYEDALI Mohammad Hasan ALIEE | 2020 | Acta Geologica Sinica(English Edition)2020，94，3： | 2 |

| 17 | Identifying the ‘unidentified’ fungi: a global-scale long-read third-generation sequencing approach显示文摘Molecular identification methods,in particular high-throughput sequencing tools,have greatly improved our knowledge about fungal diversity and biogeography,but many of the recovered taxa from natural environments cannot be identified to species or even higher taxonomic levels.This study addresses the phylogenetic placement of previously unrecognized fungal groups by using two complementary approaches:(i)third-generation amplicon sequencing analysis of DNA from global soil samples,screening out ITS reads of<90%similarity to other available Sanger sequences,and(ii)analysis of common fungal taxa that were previously indicated to be enigmatic in terms of taxonomic placement based on the ITS sequences alone(so-called top50 sequences).For the global soil samples,we chose to amplify the full rRNA gene operon using four partly overlapping amplicons and multiple newly developed primers or primer combinations that cover nearly all fungi and a vast majority of non-fungal eukaryotes.We extracted the rRNA 18S(SSU)and 28S(LSU)genes and performed phylogenetic analyses against carefully selected reference material.Both SSU and LSU analyses placed most soil sequences and top50 sequences to known orders and classes,but tens of monophyletic groups and single sequences remained outside described taxa.Furthermore,the LSU analyses recovered a few small groups of sequences that may potentially represent novel phyla.We conclude that rRNA genes-based phylogenetic analyses are efficient tools for determining phylogenetic relationships of fungal taxa that cannot be placed to any order or class using ITS sequences alone.However,in many instances,longer rRNA gene sequences and availability of both SSU and LSU reads are needed to improve taxonomic resolution.By leveraging third-generation sequencing from global soil samples,we successfully provided phylogenetic placement for many previously unidentified sequences and broadened our view on the fungal tree of life,with 10-20%new order-level taxa.In addition,the PacBio sequence data greatly extends fungal class-level information in reference databases. | Leho Tedersoo Sten Anslan Mohammad Bahram Urmas Kõljalg Kessy Abarenkov | 2020 | Fungal Diversity2020，，4： | 2 |
