| 1 | 新型PEO/纳米结构ZrO_2镁合金涂层的抗菌活性及腐蚀行为(英文)显示文摘为了增强镁合金的耐腐蚀性和抗菌活性,先采用等离子体电解氧化(PEO)在镁合金上制备一层结合层,再用空气等离子喷涂(APS)制备纳米结构ZrO_2表面涂层。采用电化学试验研究涂层样品的腐蚀行为,采用琼脂扩散法对其进行大肠杆菌病原菌抑菌活性评价,并与无涂层样品进行对比。与PEO涂层和无涂层镁合金相比,PEO/纳米ZrO_2涂层样品的腐蚀电流密度最低,电荷传递阻力最高,相位角和阻抗模量最高。PEO结合涂层被纳米ZrO_2表面涂层完全密封,能够显著延缓侵蚀性离子向镁合金表面迁移,显著提高镁合金在模拟体液(SBF)中的耐蚀性。此外,PEO/纳米ZrO_2涂层的抗菌活性也高于PEO涂层和无涂层镁合金,这是由于ZrO_2纳米颗粒通过作用于细胞膜而降低了大肠杆菌的生长速率。 | Mohammadreza DAROONPARVAR Muhamad Azizi MAT YAJID Rajeev KUMAR GUPTA Noordin MOHD YUSOF Hamid Reza BAKHSHESHI-RAD Hamidreza GHANDVAR Ehsan GHASEMI | 2018 | Transactions of Nonferrous Metals Society of China2018，28，8： | 10 |
| 2 | Performance of a novel bent-up bars system not interacting with concrete显示文摘Increasing the bending and shear capacities of reinforced concrete members is an interesting issue in structural engineering.In recent years,many studies have been carried out to improve capacities of reinforced concrete members such as using post and pre-tensioning,Fiber Reinforced Polymer and other techniques.This paper proposes a novel and significant technique to increase the flexural capacity of simply supported reinforced concrete beams.The proposed method uses a new reinforcement bar system having bent-up bars,covered with rubber tubes.This technique will avoid interaction of bent-up bars with concrete.They are located in the zone where compressive and tensile forces act against one anothe匚The compressive force in the upper point of the bent-up bars is exerted to the end point of these bars located under neutral axis.Moreover,the tensile stress is decreased in reinforcements located under the neutral axis.This will cause the Reinforced Concrete(RC)beam to endure extra loading before reaching yield stress.These factors may well be considered as reasons to increase bending capacity in the new system.The laboratory work together with finite element method analysis were carried out in this investigation.Furthermore,bending capacity,ductility,strength,and cracking zone were assessed for the new proposed system and compared with the conventional model.Both the FEM simulation and the experimental test results revealed that the proposed system has significant impact in increasing the load bearing capacity and the stiffness of the RC beams.In the present study,an equation is formulated to calculate bending capacity of a new reinforcement bar system beam. | Aydin SHISHEGARAN Mohammad Reza GHASEMI Hesam VARAEE | 2019 | Frontiers of Structural and Civil Engineering2019，13，6： | 8 |
| 3 | Modification in Media Composition to Obtain Secretory Production of STxB-based Vaccines using Escherichia coli显示文摘Shiga toxin B-subunit (STxB) from Shigella dysenteriae targets in vivo antigen to cancer cells, dendritic cells (DC) and B cells, which preferentially express the globotriaosylceramide (Gb3) receptor. This pivotal role has encouraged scientists to investigate fusing STxB with other clinical antigens. Due to the challenges of obtaining a functional soluble form of the recombinant STxB, such as formation of inclusion bodies during protein expression, scientists tend to combine STxB with vaccine candidates rather than using their genetically fused forms. In this work, we fused HPV16 E7 as a vaccine candidate to the recombinantly-produced STxB. To minimize the formation of inclusion bodies, we investigated a number of conditions during the expression procedure. Then various strategies were used in order to obtain high yield of soluble recombinant protein from E. coli which included the use of different host strains, reduction of cultivation temperature, as well as using different concentrations of IPTG and different additives (Glycin, Triton X-100, ZnCl2). Our study demonstrated the importance of optimizing incubation parameters for recombinant protein expression in E. coli; also showed that the secretion production can be achieved over the course of a few hours when using additives such as glycine and Triton X-100. Interestingly, it was shown that when the culture mediums were supplemented by additives, there was an inverse ratio between time of induction (TOI) and the level of secreted protein at lower temperatures. This study determines the optimal conditions for high yield soluble E7-STxB expression and subsequently facilitates reaching a functionally soluble form of STxB-based vaccines, which can be considered as a potent vaccine candidate for cervical cancer. | Mohammad Sadraeian Mohammad Bagher Ghoshoon Milad Mohkam Zeinab Karimi SaraRasoul-Amini Younes Ghasemi | 2013 | Virologica Sinica2013，28，1： | 7 |
| 4 | Analytical methodologies for determination of methotrexate and its metabolites in pharmaceutical,biological and environmental samples显示文摘Methotrexate(MTX)is a folate antagonist drug used for several diseases,such as cancers,various malignancies,rheumatoid arthritis(RA)and inflammatory bowel disease.Due to its structural features,including the presence of two carboxylic acid groups and its low native fluorescence,there are some challenges to develop analytical methods for its determination.MTX is metabolized to 7-hydroxymethotrexate(7-OH-MTX),2,4-diamino-N10-methylpteroic acid(DAMPA),and the active MTX polyglutamates(MTXPGs)in the liver,intestine,and red blood cells(RBCs),respectively.Additionally,the drug has a narrow therapeutic range;hence,its therapeutic drug monitoring(TDM)is necessary to regulate the pharmacokinetics of the drug and to decrease the risk of toxicity.Due to environmental toxicity of MTX;its sensitive,fast and low cost determination in workplace environments is of great interest.A large number of methodologies including high performance liquid chromatography equipped with UVevisible,fluorescence,or electrochemical detection,liquid chromatography-mass spectroscopy,capillary electrophoresis,UVevisible spectrophotometry,and electrochemical methods have been developed for the quantitation of MTX and its metabolites in pharmaceutical,biological,and environmental samples.This paper will attempt to review several published methodologies and the instrumental conditions,which have been applied to measure MTX and its metabolites within the last decade. | Forough Karami Sara Ranjbar Younes Ghasemi Manica Negahdaripour | 2019 | Journal of Pharmaceutical Analysis2019，9，6： | 7 |
| 5 | Progress in the development of vaccines for hepatitis C virus infection显示文摘The hepatitis C virus(HCV), first described in 1989, is now a leading cause of liver cirrhosis and hepatocellular carcinoma. With more than 170 million people infected globally, this virus is a major public health issue. The current standard therapy is based on interferon in combination with ribavirin. This costly therapy often fails to completely clear the infection and is associated with adverse side effects. Recent anti-HCV therapies are interferon-free direct-acting antiviral(DAA) regimens for HCV, including simeprevir, sofosbuvir, and ledipasvir, which have effects on non-structural proteins. DAA regimens have several advantages, such as specifically targeting HCV viral replication, accompanied by very high sustained virological response rates and lower side effects like flu-like syndrome. These facts plus the fact that most HCV cases progress to chronic infection suggest the potential need for an efficient HCV vaccine. Different innovative methods, including methods based on peptide, recombinant protein, DNA, vector-based, and virus-like particles, have been introduced for the development of HCV vaccines. An extensive number of studies have been published on these vaccines, and some vaccines were even tested in clinical trials. In the current review, progress in the development of preventive and therapeutic vaccines against the HCV is reviewed in the context of peptide vaccines, recombinant protein vaccines, HCV-like particle, DNA vaccines and viral vectors expressing HCV genes. | Faezeh Ghasemi Sina Rostami Zahra Meshkat | 2015 | World Journal of Gastroenterology2015，21，42： | 6 |

| 7 | Computational Machine Learning Representation for the Flexoelectricity Effect in Truncated Pyramid Structures显示文摘In this study,machine learning representation is introduced to evaluate the flexoelectricity effect in truncated pyramid nanostructure under compression.A Non-Uniform Rational B-spline(NURBS)based IGA formulation is employed to model the flexoelectricity.We investigate 2D system with an isotropic linear elastic material under plane strain conditions discretized by 45×30 grid of B-spline elements.Six input parameters are selected to construct a deep neural network(DNN)model.They are the Young's modulus,two dielectric permittivity constants,the longitudinal and transversal flexoelectric coefficients and the order of the shape function.The outputs of interest are the strain in the stress direction and the electric potential due flexoelectricity.The dataset are generated from the forward analysis of the flexoelectric model.80%of the dataset is used for training purpose while the remaining is used for validation by checking the mean squared error.In addition to the input and output layers,the developed DNN model is composed of four hidden layers.The results showed high predictions capabilities of the proposed method with much lower computational time in comparison to the numerical model. | Khader M.Hamdia Hamid Ghasemi Xiaoying Zhuang Naif Alajlan Timon Rabczuk | 2019 | Computers, Materials & Continua2019，，4： | 5 |
| 8 | Assessing the seismic behavior of steel moment frames equipped by elliptical brace through incremental dynamic analysis(IDA)显示文摘Incremental dynamic analysis and nonlinear static pushover analysis are carried out on a performance-based design to determine the seismic demands and capacities of an elliptic braced moment resisting frame(ELBRF).The objective is to assess ductility,overstrength and response modification factors in a modern steel-braced structural system based on incremental dynamic analysis.This integrated system is connected to a beam and column with an appropriate length while providing enough architectural space to allow for an opening without having the common problems associated with architectural spaces in braced systems.Several different classes of buildings are considered on soil type II.Linear dynamic analysis,nonlinear static pushover analysis and incremental nonlinear dynamic analysis related to 12 records from past earthquakes are carried out using OpenSees software.The factors of ductility,overstrength and response modification are calculated for this system.The values of 9.5 and 6.5 are found and suggested only for the response modification factor for ELBRF systems in allowable stress and ultimate limit state methods,respectively.The fragility curves are plotted for the first time for this type of bracing,which contributes to the assessment of building seismic damage. | Ghasemi Jouneghani Abbas Haghollahi | 2020 | Earthquake Engineering and Engineering Vibration2020，19，2： | 4 |
| 9 | Synthesis of Gd_2O_3 nanoparticles:using bulk Gd_2O_3 powders as precursor显示文摘Gd2O3nanoparticles were synthesized from the commercial bulk Gd2O3 powders via a simple electrochemical method. The synthesized powders were characterized by means of X-ray powder diffraction(XRD),scanning electron microscopy(SEM), transmission electron microscopy(TEM) and Fourier transform infrared(FTIR) spectroscopy. The effects of solution p H on the morphological features of the sample were studied. The strategy developed in this study offers significant advantages for the synthesis of Gd2O3 nanoparticles from the bulk Gd2O3 powders compared with the conventional routes. From SEM observations, the size of the Gd2O3 nanoparticles is estimated to be significantly smaller than70 nm. | Taher Yousefi Meisam Torab-Mostaedi Mostafa Ghasemi Amir Ghadirifar | 2015 | Rare Metals2015，34，8： | 4 |
| 10 | Interactive effects of drought stress and chitosan application on physiological characteristics and essential oil yield of Thymus daenensis Celak显示文摘Thymus daenensis, a perennial herb, is often grown in areas that experience drought conditions during its growing period. Application of chitosan may compensate for the negative impact of drought stress on the yield of oil and secondary metabolites in Thymus.The interactive effects of foliar application of chitosan and drought stress on dry matter,essential oil yield, and selected physiological characteristics including photosynthetic pigments, osmotic adjustment, and lipid peroxidation of Thymus were investigated in a two-year study from 2014 to 2015. Treatments consisted of 0, 200, and 400(iL L'1 chitosan applied to plants grown under field capacity, mild drought stress(50% field capacity), and severe drought stress(25% field capacity). Dry matter yield decreased substantially as drought stress intensified. However, essential oil content increased under stress conditions,with the highest essential oil yield obtained from plants under mild drought stress. Foliar application of chitosan compensated to some extent for dry matter and oil yield reduction of plants grown under drought stress. The highest essential oil yield(1.52 g plant-1) was obtained by application of 400 \iL L_1 chitosan under the mild stress condition in 2015 when plants were mature. The compensatory effect of chitosan in reducing the negative impact of stress conditions on dry matter and oil yield was due mainly to stimulation of osmotic adjustment through proline accumulation and reduction of lipid peroxidase level, which increased the integrity of cell membranes of thyme leaves. | Zohreh Emami Bistgani Seyed Ataollah Siadat Abdolmehdi Bakhshandeh Abdollah Ghasemi Pirbalouti Masoud Hashemi | 2017 | The Crop Journal2017，5，5： | 4 |
| 11 | Aminobenzenesulfonamide functionalized SBA-15 nanoporous molecular sieve: A new and promising adsorbent for preconcentration of lead and copper ions显示文摘A rapid method for the extraction and monitoring of nanogram level of Pb2+ and Cu2+ ions using uniform silanized mesopor (SBA-15) functionalized with aminobenzenesulfonamide groups and flame atomic absorption spectrometry (FAAS) is presented. Aminobenzenesulfonamide functionalized SBA-15 was synthesized according to procedure in the literature and the presence of organic groups in the silica framework was demonstrated by FT-IR spectra. The functionalized product showed the BET surface area 110 m2/g and pore diameter 5.1 nm, based on adsorption-desorption of N2 at 77 K. The effect of several variables such as (amount of adsorbent, stirring time, pH and presence of other ions in the medium) has been studied. Lead and copper were completely extracted at pH greater than 3 after stirring for 10 min. The maximum capacity of the adsorbent was found to be 191.3 ± 1.4 and 155.0 ± 1.0 μg of lead and copper ions/mg functionalized SBA-15, respectively. The preconcentration factor of the method was found to be 200. The detection limit of the technique was 3.4 and 0.4 ng/mL for Pb2+ and Cu2+, respectively. The applications of this methodology for real samples were examined by various water type, black tea and pepper samples. | Leila Hajiaghababaei Babak Ghasemi Alireza Badiei Hassan Goldooz Mohammad Reza Ganjali Ghodsi Mohammadi Ziarani | 2012 | Journal of Environmental Sciences2012，24，7： | 3 |
| 12 | Microstructures, hardening and tribological behaviors of tin matrix composites reinforced with SiC and Zn particles显示文摘In order to strengthen pure tin and improve its dry sliding resistance, Sn/SiC and Sn/Zn composites were fabricated via a powder metallurgy route. Microstructure,hardness and pin-on-disk wear resistance of pure tin and the fabricated composites were compared to those of Sn–7.5 Sb–3.5 Cu Babbitt alloy. The dominant wear mechanism at different applied loads was determined by analyzing worn surfaces and wear debris in each case. The results showed that the hardening effect of Zn was much higher than that of SiC. The hardening role of Zn in the tin matrix was ascribed to the direct load transfer mechanism. Microscopic studies of the worn surfaces revealed that the pure tin was susceptible to surface fatigue wear and plowing damage, depending on the normal load applied during the wear test. In the case of Sn/SiC composite and the Babbitt alloy, delamination wear mechanism resulting from subsurface crack propagation controlled the wear rate. While the highest hardness and the lowest coefficient of friction were obtained for the Babbitt alloy, the Sn/Zn composite exhibited the highest wear resistance at a constant applied load, indicating the importance of asperity contact type in the wear process. | Fatemeh Ghasemi Mohammad Moazami-Goudarzi Hamidreza Najafi | 2021 | Rare Metals2021，40，9： | 3 |
| 13 | Assessment of different topographic correction methods in ALOS AVNIR-2 data over a forest area显示文摘Because the removal of topographic effects is one the most important preprocessing steps when extracting information from satellite images in digital Earth applications,the problem of differential terrain illumination on satellite imagery has been investigated for at least 20 years.As there is no superior topographic correction method applicable to all areas and all images,a comparison of topographic normalization methods in different regions and images is necessary.In this study,common topographic correction methods were applied on an ALOS AVNIR-2 image of a rugged forest area,and the results were evaluated through different criteria.The results show that the simple correction methods[Cosine,Sun-Canopy-sensor(SCS),and Minnaert correction]are inefficient in exceptionally rough forests.Among the improved correction methods(SCSC,modified Minnaert,and pixel-based Minnaert),the best result was achieved using a pixel-based Minnaert approach in which a separate correction factor in various slope angles is used.Thus,this method should be considered for topographic correction,especially in forests with severe topography. | Nafiseh Ghasemi Ali Mohammadzadeh Mahmod Reza Sahebi | 2013 | International Journal of Digital Earth2013，6，5： | 3 |
| 14 | Coupling system application in photocatalytic degradation of methylorange by TiO_2, TiO_2/SiO_2 and TiO_2/SiO_2/Ag显示文摘Three different photocatalysts including TiO_2,TiO_2/SiO_2 and TiO_2/SiO_2/Ag were synthesized via sol-gel growth method,in which colloidal silica was used as Si source,titanium tetra iso-propoxide(TTiP) as titanium source,Ag^+ as dopant ion and hydroxypropyl cellulose(HPC) as dispersant.The purpose was to study the enhancement of photocatalytic activity of TiO_2 by deposition on SiO_2 colloids and also doping with Ag ion.The catalysts were characterized using X-ray diffraction(XRD),transmission electron microscopy(TEM),X-ray fluorescence(XRF),Fourier transform infrared spectroscopy(FT-IR)and Brunauer-Emmett-Teller(BET) methods.It is confirmed that the major phase in all catalysts is anatase.Photocatalytic activity was studied in various conditions for degradation of methylorange(as a model pollutant) to evaluate the effect of some parameters on degradation efficiency.Studying the degradation process in various pH values reveals that the degradation is more efficient in acidic solution than alkaline condition.Coupling the photocatalytic process with some fields called electro-photochemical(EP),magnetic-photochemical(MP) and ultrasonic-photochemical(UP) was studied at two pH values which were compared with photochemical(P) alone.It is concluded that in most cases,the EP is the best coupled system and has the maximum efficiency.Liquid chromatography-mass spectrometry(LC-MS)analysis was used to check the complete decomposition of methylorange at the end of process. | Hossein Ghasemi Mobtaker Seyed Javad Ahmadi Shahram Moradi Dehaghi Taher Yousefi | 2015 | Rare Metals2015，34，12： | 3 |
| 15 | Experimental Analysis and Evaluation of Thermostat Effects on Engine Cooling System显示文摘Thermostat as a part of engine cooling system has a significant role in the shortening warm-up time and regulating the engine in proper temperature to approach optimal performance.Whereas,there is not adequate research on this part of the cooling system and its responsibility.Considering this gap and also being used in large scale,this study is intended to evaluate performance and reflex of the wax type thermostat in different engine working conditions.In this regard,performance of engine cooling system was investigated in various engine speeds and loads to reveal positive and negative influences of thermostat on engine cooling efficiency and engine performance.According to observed results,warm-up period and fuel consumption decrease by using a thermostat.On the other hand,however,the temperature oscillation of coolant fluid passing through engine increases sharply,which causes a disruption in the regulating engine temperature and also a possibility of the fluid boiling rises in some regions of the engine that increases the risk of damage in the engine parts.Engine temperature,fuel consumption,warm-up duration and emissions were provided and compared in two operation modes,with and without thermostat. | GHASEMI ZAVARAGH Hadi KALELI Alirlza SOLMUS Ismail AFSHARI Faraz | 2021 | Journal of Thermal Science2021，30，2： | 3 |

| 17 | A two-stage DEA model to evaluate sustainability and energy efficiency of tomato production显示文摘The aims of this study were to evaluate the sustainability and efficiency of tomato production and to investigate the determinants of inefficiency of tomato farming in Marand region of East Azerbaijan province,Iran.For these purposes,a two-stage methodology was applied,in which for the first time a fractional regression model(FRM)was employed in the second stage of analysis,so that,in the first stage a nonparametric Data Envelopment Analysis(DEA)was used to analyze the efficiencies of tomato production and in the second stage,farm specific variables such as education level,farmers’age,total land size and use of manure were used in a fractional regression model to explain how these factors influenced efficiency of tomato farming.The results of the first stage showed that there are considerable differences between efficient and inefficient farmers in the studied area,so that the main differences were in the use of chemical fertilizers,biocides and water for irrigation.Also,the results of second stage revealed that farmers’age,education level and total land size positively affected efficiency in tomato production.So,better use of land,chemical fertilizers,water for irrigation and improving the farmers’educational levels through literacy campaign and land consolidation would probably increase the efficiency in the long term. | Hossein Raheli Rassul Mohammad Rezaei Mehri Raei Jadidi Hassan Ghasemi Mobtaker | 2017 | Information Processing in Agriculture2017，4，4： | 2 |
| 18 | Pre-sowing treatment for breaking dormancy in Acer velutinum Boiss. seed lots显示文摘Acer velutinum Boiss is a valuable tree species native to Iran, and its seeds possess physiological dormancy that hampers seedling production in the nursery for large-scale reforestation efforts. The aim of this study was to determine the optimal dormancy breaking treatments for A. velutinum seeds. We conducted a factorial experiment involving six seed lots collected along an elevation gradient from 300 to 1800 m at 300 m interval and four cold-moist stratification periods (0, 4, 8 and 16 weeks) at 4℃ and 70% relative humidity. The result shows that the germination of cold-moist stratified seeds was significantly (p < 0.0001) higher than the control for all seed lots. The highest germination capacity was recorded after 16 weeks of cold-moist stratification for all seed lots (68% 88% depending on the seed lot) except those collected from mid altitude sites (600 and 900 m) that germinated equally well (≥ 75%) after 4and 8-week of clod-moist stratification compared to the other seed lots. The mean germination time was significantly shorter (12 to 19 days, depending on the seed lot) for seeds stratified for 16 weeks than for untreated seeds. It can be concluded that: (1) cold-moist stratification for 16 weeks is the best pre-sowing treatment for breaking dormancy in A. velutinum seeds; and (2) seeds should be collected from mid altitude sites (600 and 900 m) to get more than 80% germination within 15 days, and these seed lots even required shorter cold-moist stratification period(eight weeks) than other seed lots. | Mostafa Farhadi Mulualem Tigabu Alireza Ghasemi Arian Mehdi Sharifani Abolfazl Daneshvar Per Christer Oden | 2013 | Journal of Forestry Research2013，24，2： | 2 |
| 19 | Three-Dimensional Isogeometric Analysis of Flexoelectricity with MATLAB Implementation显示文摘Flexoelectricity is a general electromechanical phenomenon where the electric polarization exhibits a linear dependency to the gradient of mechanical strain and vice versa.The truncated pyramid compression test is among the most common setups to estimate the flexoelectric effect.We present a three-dimensional isogeometric formulation of flexoelectricity with its MATLAB implementation for a truncated pyramid setup.Besides educational purposes,this paper presents a precise computational model to illustrate how the localization of strain gradients around pyramidal boundary shapes contributes in generation of electrical energy.The MATLAB code is supposed to help learners in the Isogeometric Analysis and Finite Elements Methods community to learn how to solve a fully coupled problem,which requires higher order approximations,numerically.The complete MATLAB code which is available as source code distributed under a BSD-style license,is provided in the part of Supplementary Materials of the paper. | Hamid Ghasemi Harold S.Park Xiaoying Zhuang Timon Rabczuk | 2020 | Computers, Materials & Continua2020，，11： | 2 |
