| 1 | Anther and pollen development:A conserved developmental pathway显示文摘Pollen development is a critical step in plant development that is needed for successful breeding and seed formation.Manipulation of male fertility has proved a useful trait for hybrid breeding and increased crop yield.However,although there is a good understanding developing of the molecular mechanisms of anther and pollen anther development in model species,such as Arabidopsis and rice,little is known about the equivalent processes in important crops.Nevertheless the onset of increased genomic information and genetic tools is facilitating translation of information from the models to crops,such as barley and wheat;this will enable increased understanding and manipulation of these pathways for agricultural improvement. | José Fernndez Gmez Behzad Talle Zoe A Wilson | 2015 | Journal of Integrative Plant Biology2015，57，11： | 33 |
| 2 | Warpage and Shrinkage Optimization of Injection-Molded Plastic Spoon Parts for Biodegradable Polymers Using Taguchi, ANOVA and Artificial Neural Network Methods显示文摘In this study, it is attempted to give an insight into the injection processability of three self-prepared polymers from A to Z. This work presents material analysis, injection molding simulation, design of experiments alongside considering all interaction effects of controlling parameters carefully for green biodegradable polymeric systems, including polylactic acid(PLA), polylactic acid-thermoplastic polyurethane(PLA-TPU) and polylactic acid-thermoplastic starch(PLA-TPS). The experiments were carried out using injection molding simulation software Autodesk Moldflow?in order to minimize warpage and volumetric shrinkage for each of the mentioned systems. The analysis was conducted by changing five significant processing parameters, including coolant temperature, packing time, packing pressure, mold temperature and melt temperature. Taguchi's L27(35) orthogonal array was selected as an efficient method for design of simulations in order to consider the interaction effects of the parameters and reduce spurious simulations. Meanwhile, artificial neural network(ANN) was also used for pattern recognition and optimization through modifying the processing conditions. The Taguchi coupled analysis of variance(ANOVA) and ANN analysis resulted in definition of optimum levels for each factor by two completely different methods. According to the results, melting temperature, coolant temperature and packing time had significant influence on the shrinkage and warpage. The ANN optimal level selection for minimization of shrinkage and/or warpage is in good agreement with ANOVA optimal level selection results. This investigation indicates that PLA-TPU compound exhibits the highest resistance to warpage and shrinkage defects compared to the other studied compounds. | Erfan Oliaei Behzad Shiroud Heidari Seyed Mohammad Davachi Mozhgan Bahrami Saeed Davoodi Iman Hejazi Javad Seyfi | 2016 | Journal of Materials Science & Technology2016，32，8： | 26 |
| 3 | Hepatitis B and C virus-induced hepatitis: Apoptosis, autophagy, and unfolded protein response显示文摘AIM: To investigate the co-incidence of apoptosis, autophagy, and unfolded protein response(UPR) in hepatitis B(HBV) and C(HCV) infected hepatocytes.METHODS: We performed immunofluorescence confocal microscopy on 10 liver biopsies from HBV and HCV patients and tissue microarrays of HBV positive liver samples. We used specific antibodies for LC3β, cleaved caspase-3, BIP(GRP78), and XBP1 to detect autophagy, apoptosis and UPR, respectively. AntiHCV NS3 and anti-HBs antibodies were also used to confirm infection. We performed triple blind counting of events to determine the co-incidence of autophagy(LC3β punctuate), apoptosis(cleaved caspase-3), and unfolded protein response(GRP78) with HBV and HCV infection in hepatocytes. All statistical analyses were performed using SPSS software for Windows(Version 16 SPSS Inc, Chicago, IL, United States). P-values < 0.05 were considered statistically significant. Statistical analyses were performed with Mann-Whitney test to compare incidence rates for autophagy, apoptosis, and UPR in HBV- and HCV-infected cells and adjacent noninfected cells.RESULTS: Our results showed that infection of hepatocytes with either HBV and HCV induces significant increase(P < 0.001) in apoptosis(cleavage of caspase-3), autophagy(LC3β punctate), and UPR(increase in GRP78 expression) in the HCV- and HBVinfected cells, as compared to non-infected cells of the same biopsy sections. Our tissue microarray immunohistochemical expression analysis of LC3β in HBV^(Neg) and HBV^(Pos) revealed that majority of HBVinfected hepatocytes display strong positive stainingfor LC3β. Interestingly, although XBP splicing in HBVinfected cells was significantly higher(P < 0.05), our analyses show a slight increase of XBP splicing was in HCV-infected cells(P > 0.05). Furthermore, our evaluation of patients with HBV and HCV infection based on stage and grade of the liver diseases revealed no correlation between these pathological findings and induction of apoptosis, autophagy, and UPR.CONCLUSION: The results of this study indicate that HCV and HBV infection activates apoptosis, autophagy and UPR, but slightly differently by each virus. Further studies are warranted to elucidate the interconnections between these pathways in relation to pathology of HCV and HBV in the liver tissue. | Behzad Yeganeh Adel Rezaei Moghadam Javad Alizadeh Emilia Wiechec Seyed Moayed Alavian Mohammad Hashemi Bita Geramizadeh Afshin Samali Kamran Bagheri Lankarani Martin Post Payam Peymani Kevin M Coombs Saeid Ghavami | 2015 | World Journal of Gastroenterology2015，21，47： | 13 |
| 4 | NUMERICAL SIMULATION OF FLOW OVER TWO CIRCULAR CYLINDERS IN TANDEM ARRANGEMENT显示文摘In this article,the 2-D unsteady viscous flow around two circular cylinders in a tandem arrangement is numerically simulated in order to study the characteristics of the flow in both laminar and turbulent regimes.The method applied alternatively is based on the finite volume method on a Cartesian-staggered grid.The great source term technique is employed to identify the cylinders placed in the flow field.To apply the boundary conditions,the ghost-cell technique is used.The implemented computational method is firstly validated through simulation of laminar and turbulent flows around a fixed circular cylinder.Finally,the flow around two circular cylinders in a tandem arrangement is simulated and analyzed.The flow visualization parameters,the Strouhal numbers,and drag and lift coefficients are comprehensively presented and compared for different cases in order to reveal the effect of the Reynolds number and gap spacing on the behavior of the flow.The obtained results have shown two completely distinct flow characteristics in laminar and turbulent regimes. | DEHKORDI Behzad Ghadiri MOGHADDAM Hesam Sarvghad JAFARI Hamed Houri | 2011 | Journal of Hydrodynamics2011，23，1： | 11 |
| 5 | Effects of nanobubble and hydrodynamic parameters on coarse quartz flotation显示文摘Quartz, the second most abundant mineral in the earth's crust, is a gangue mineral in practically every flotation process. Coarse quartz flotation has been a long standing problem in various mineral processing plants to reduce milling cost and increase valuable mineral recovery. Based on this, the effects of nanobubbles(NBs) and hydrodynamic parameters on coarse quartz particle flotation were systematically investigated. Mechanical flotation experiments were carried out using the 7 cm and 9 cm diameter impellers in order to produce different hydrodynamic conditions. 900–1300 rpm impeller speeds were used for the 7 cm diameter impeller and 554–786 rpm for the 9 cm diameter impeller. The results show that the presence of NBs increased the flotation recovery of à425 + 106 lm quartz by up to 21%. For the7 cm diameter impeller, the maximum flotation recoveries of 86.4% and 98% were obtained in the absence and presence of NBs at Reynolds number(Re) of 81,000 and 66,000, respectively. For the 9 cm diameter impeller, the maximum recoveries of 86.3% and 97.5% were obtained in the absence and presence of NBs at Re of 90,000 and 75,000, respectively. NBs increased the flotation rate constant up to 36%. | Sabereh Nazari Sied Ziaedin Shafaei Mahdi Gharabaghi Rahman Ahmadi Behzad Shahbazi Fan Maoming | 2019 | International Journal of Mining Science and Technology2019，29，2： | 10 |
| 6 | 不同铸造工艺制备A356-CNT纳米复合材料的摩擦学行为(英文)显示文摘研究液态成形和半固态成形法制备的A356 铝合金整体铸件和A356-CNT 纳米复合铸造件的摩擦学行为。采用熔体搅拌、流变铸造、搅拌铸造、复合铸造等不同工艺制备样品。研究碳纳米管(CNTs)的加入、铸造工艺和施加载荷对磨损性能和磨损机理的影响。结果表明,添加碳纳米管显著降低了纳米复合材料的磨损量、磨损率和摩擦因数。铸造工艺由液态成形变为半固态成形,和初相含量的增加是提高合金尤其是纳米复合合金样品耐磨性能的两个主要因素。此外,研究还发现液态成形和半固态成形两种方法制备的整体铸件其主要磨损机理分别是粘着磨损和剥层磨损。然而,无论制备工艺如何,磨粒磨损是纳米复合材料的主要磨损机理。 | Benyamin ABBASIPOUR Behzad NIROUMAND Sayed Mahmoud MONIR VAGHEFI Mohammad ABEDI | 2019 | Transactions of Nonferrous Metals Society of China2019，29，10： | 9 |

| 9 | 高压直流换流站穿墙套管的局部放电在线测量(英文)显示文摘An online partial discharge(PD) measurement performed on a high voltage direct current(HVDC) wall bushing successfully identified the presence of internal discharges.The wall bushing is a sulfur hexafluoride gas-insulated bushing,rated for 500 kV dc and terminated on a thyristor-controlled HVDC converter bridge.The measurement of PD within the HVDC station environment is particularly challenging due to the high levels of electromagnetic noise caused by thyristor switching events and external air-corona from the neighboring high-voltage equipment.An additional challenge is the''mixed'voltage stress on the bushing insulation,which has both ac and dc high-voltage components.There are also fast transients during the firing of thyristors in the HVDC conversion process that cause added stress to the insulation.As a result,the analysis and interpretation of PD data for HVDC equipment is more complex;PD pulses may occur in response to the ac,dc,or switching transient voltage stresses.In this paper,an online PD measurement strategy for noise filtering and isolation of PD sources within the bushing are discussed.The PD measurement data is plotted on a phase-resolved diagram where the line supply power cord voltage was used as a reference. The phase-resolved diagram appears to suggest that the fast transients,caused during switching,trigger some PD events.Measurements were also performed with the aid of a modern PD measurement instrument having noise separation capabilities.The findings from the online PD measurements are verified with physical evidence,found after the bushing was removed from service,suggested internal PD had occurred inside the bushing. | Nathan D.Jacob William M.McDermid Behzad Kordi | 2011 | 高电压技术2011，37，11： | 8 |
| 10 | Effect of post-harvest UV-C irradiation and calcium chloride on enzymatic activity and decay of tomato(Lycopersicon esculentum L.)fruit during storage显示文摘Tomato is one of the extensively consumed vegetable crops worldwide. The regular consumption of tomato decreases the incidence of chronic degenerative diseases such as certain types of cancer and cardiovascular diseases. The objective of this study was to find an appropriate method that not only reduces tomatoes decay, but also maintains its post-harvest quality. A factorial experiment based on randomized complete block design with three replications was conducted to evaluate effects of ultraviolet(UV)-C and CaCl_2 applications on tomato during storage. The traits studied included ethylene, polygalacturonase(PG) activity, pectin methyl esterase(PME) activity, firmness, total phenol content, and fungal-induced decay were measured weekly during 35 days of storage. Both UV-C and CaCl_2 treatments had positive effects on tomato quality as compared to control treatment. The 3 and 4.5 k J m^(-2) levels of UV-C and 2% CaCl_2 had positive effects on quality characteristics, respectivly. Fruits treated by UV-C and CaCl_2 had higher phenol and firmness, and less PME activity, PG activity, ethylene production, and decay than the control fruits. In conclusion, increasing in storage duration significantly affected the fruits quality by increasing in ethylene, PME activity, PG activity, decay and decreasing the phenol content and firmness. But UV-C and CaCl_2 led to significant decrease in this adverse impact relative to control treatment. | Saeideh Mansourbahmani Behzad Ghareyazie Sepideh Kalatejari Reza Salehi Mohammadi Vahid Zarinnia | 2017 | Journal of Integrative Agriculture2017，16，9： | 7 |
| 11 | NUMERICAL SIMULATION OF FLOW OVER TWO SIDE-BY-SIDE CIRCULAR CYLINDERS显示文摘In the present paper, the unsteady, viscous, incompressible and 2-D flow around two side-by-side circular cylinders was simulated using a Cartesian-staggered grid finite volume based method. A great-source term technique was employed to identify the solid bodies (cylinders) located in the flow field and boundary conditions were enforced by applying the ghost-cell technique. Finally, the characteristics of the flow around two side-by-side cylinders were comprehensively obtained through several computational simulations. The computational simulations were performed for different transverse gap ratios (1.5≤T/D≤4) in laminar (Re=100,200) and turbulent (Re=104) regimes, where T and D are the distance between the centers of cylinders and the diameter of cylinders, respectively. The Reynolds number is based on the diameter of cylinders,D. The pressure field and vorticity distributions along with the associated streamlines and the time histories of hydrodynamic forces were also calculated and analyzed for different gap ratios. Generally, different flow patterns were observed as the gap ratio and Reynolds number varied. Accordingly, the hydrodynamic forces showed irregular variations for small gaps while they took a regular pattern at higher spacing ratios. | SARVGHAD-MOGHADDAM Hesam NOOREDIN Navid GHADIRI-DEHKORDI Behzad | 2011 | Journal of Hydrodynamics2011，23，6： | 7 |
| 12 | Hydrophobic silica nanoparticle-stabilized invert emulsion as drilling fluid for deep drilling显示文摘An oil-based drilling fluid should be stable and tolerant to high temperatures for use in deep drilling. An invert emulsion of water in oil is a good choice as an oilbased drilling fluid which is a mixture of a solid phase and two immiscible liquid phases stabilized by a polymeric surfactant. In deep drilling, due to high temperatures, the polymeric surfactant degrades and a phase separation occurs. Here, octadecyltrimethoxysilane-modified silica nanoparticles were used to form a stable invert emulsion of water in oil for the drilling fluid model which resulted in a milky fluid with the formation of 60 μm water droplets. In addition, rheological study showed that using hydrophobic silica nanoparticles resulted in a stable water in oil invert emulsion with desired properties for a drilling fluid that can be modified by adjusting the nanoparticle nature and content. Aging experiments at 120 °C indicated that they also have good stability at high temperatures for challenging drilling operations. | Maliheh Dargahi-Zaboli Eghbal Sahraei Behzad Pourabbas | 2017 | Petroleum Science2017，14，1： | 7 |
| 13 | Investigation of rock salt layer creep and its effects on casing collapse显示文摘Casing collapse is one of the costly incidents in the oil industry. In the oil fields of southwest Iran, most casing collapses have occurred in Gachsaran formation, and the halite rock salt layer in this formation may be the main cause for these incidents because of its peculiar creep behavior. In this research, triaxial creep experiments have been conducted on Gachsaran salt samples under various temperatures and differential stresses. The main purpose was to determine the creep characteristics of Gachsaran rock salt,and to examine the role of creep in several casing collapses that occurred in this formation. Results indicated that the halite rock salt of Gachsaran formation basically obeys the power law;however, its creep parameters are quite different from other halite rocks elsewhere. The time-dependent creep of Gachsaran rock salt exhibits strong sensitivity to temperature change;however, its sensitivity to variation of differential stress is rather low. The numerical simulation of the rock salt creep in a real oil well demonstrated the importance of creep and reservoir conditions on the safety factor of the tubing related to casing collapse. | S.Reza Taheri Ali Pak Saeed Shad Behzad Mehrgini Meisam Razifar | 2020 | International Journal of Mining Science and Technology2020，30，3： | 6 |
| 14 | Optimization of energy consumption and environmental impacts of chickpea production using data envelopment analysis(DEA)and multi objective genetic algorithm(MOGA)approaches显示文摘Energy consumption in agricultural products and its environmental damages has increased in recent centuries.Life cycle assessment(LCA)has been introduced as a suitable tool for evaluation environmental impacts related to a product over its life cycle.In this study,optimization of energy consumption and environmental impacts of chickpea production was conducted using data envelopment analysis(DEA)and multi objective genetic algorithm(MOGA)techniques.Data were collected from 110 chickpea production enterprises using a face to face questionnaire in the cropping season of 2014-2015.The results of optimization revealed that,when applying MOGA,optimum energy requirement for chickpea production was significantly lower compared to application of DEA technique;so that,total energy requirement in optimum situation was found to be 31511.72 and 27570.61 MJ ha^-1 by using DEA and MOGA techniques,respectively;showing a reduction by 5.11%and 17%relative to current situation of energy consumption.Optimization of environmental impacts by application of MOGA resulted in reduction of acidification potential(ACP),eutrophication potential(EUP),global warming potential(GWP),human toxicity potential(HTP)and terrestrial ecotoxicity potential(TEP)by 29%,23%,10%,6%and 36%,respectively.MOGAwas capable of reducing the energy consumption from machinery,farmyard manure(FYM)diesel fuel and nitrogen fertilizer(the mostly contributed inputs to the environmental emissions)by 59%,28.5%,24.58%and 11.24%,respectively.Overall,the MOGA technique showed a superior performance relative to DEA approach for optimizing energy inputs and reducing environmental impacts of chickpea production system. | Behzad Elhami Asadollah Akram Majid Khanali | 2016 | Information Processing in Agriculture2016，3，3： | 6 |

| 17 | Selective methanation of carbon monoxide in hydrogen rich stream over Ni/CeO_2 nanocatalysts显示文摘In the present work, selective methanation of carbon monoxide in hydrogen rich stream was investigated over Ni/CeO2 nanocatalysts. The obtained results revealed that increasing in nickel loading decreased the BET surface area, pore volume and nickel dispersion. The 25% Ni/CeO2 with a NiO crystal size of 12 nm exhibited the highest activity in CO methanation reaction and reached to maximum CO conversion and CH4 selectivity at temperatures above 230 ℃. The catalytic results revealed that CO selective methanation well progressed at lower temperatures while CO2 methanation was completely suppressed until CO conversion reached to maximum value. | Behzad Nematollahi Mehran Rezaei Ebrahim Nemati Lay | 2015 | Journal of Rare Earths2015，33，6： | 6 |
| 18 | Combined application of Artificial Neural Networks and life cycle assessment in lentil farming in Iran显示文摘In this study,an Artificial Neural Network(ANN)was applied to model yield and environmental emissions from lentil cultivation in Esfahan province of Iran.Data was gathered from lentil farmers using face to face questionnaire method during 2014–2015 cropping season.Life cycle assessment(LCA)was applied to investigate the environmental impact categories associated with lentil production.Based on the results,total energy input,energy output to input ratio and energy productivity were determined to be 32,970.10 MJ ha1,0.902 and 0.06 kg MJ1,respectively.The greatest amount of energy consumption was attributed to chemical fertilizer(42.76%).Environmental analysis indicated that the acidification potential was higher than other environmental impact categories in lentil production system.Also results showed that the production of agricultural machinery was the main hotspot in abiotic depletion,eutrophication,global warming,human toxicity,fresh water aquatic ecotoxicity,marine aquatic ecotoxicity and terrestrial ecotoxicity impact categories,while direct emissions associated with lentil cultivation was the main hotspot in acidification potential and photochemical oxidation potential.In addition,diesel fuel was the main hotspot only in ozone layer depletion.The ANN model with 9-10-6-11 structure was identified as the most appropriate network for predicting yield and related environmental impact categories of lentil cultivation.Overall,the results of sensitivity analysis revealed that farmyard manure had the greatest effect on the most of the environmental impacts,while machinery was the most affecting parameter on the yield of the crop. | Behzad Elhami Majid Khanali Asadollah Akram | 2017 | Information Processing in Agriculture2017，4，1： | 6 |
| 19 | Estimation of froth flotation recovery and collision probability based on operational parameters using an artificial neural network显示文摘An artificial neural network and regression procedures were used to predict the recovery and collision probability of quartz flotation concentrate in different operational conditions. Flotation parameters, such as dimensionless numbers (Froude, Reynolds, and Weber), particle size, air flow rate, bubble diameter, and bubble rise velocity, were used as inputs to both methods. The linear regression method shows that the relationships between flotation parameters and the recovery and collision probability of flotation can achieve correlation coefficients (R2) of 0.54 and 0.87, respectively. A feed-forward artificial neural network with 3-3-3-2 arrangement is able to simultaneously estimate the recovery and collision probability as the outputs. In testing stages, the quite satisfactory correlation coefficient of 0.98 was achieved for both outputs. It shows that the proposed neural network models can be used to determine the most advantageous operational conditions for the expected recovery and collision probability in the froth flotation process. | Saeed Chehreh Chelgani Behzad Shahbazi Bahram Rezai | 2010 | International Journal of Minerals,Metallurgy and Materials2010，17，5： | 5 |
