| 1 | Evaluation of photosynthesis, physiological, and biochemical responses of chickpea (Cicer arietinum L. cv. Pirouz) under water deficit stress and use of vermicompost fertilizer显示文摘One goal in the face of drought stress conditions is to increase growth and yield through the reduction of negative effects of stress. Vermicompost can play an effective role in plant growth and development and in reducing harmful effects of various environmental stresses on plants due to its porous structure, high water storage capacity, having hormone-like substances, plant growth regulators, and high levels of macro and micro nutrients. This study considered the physiological, biochemical, and photosynthetic responses of the chickpea to different combinations of vermicompost and water stress in a greenhouse environment. Two factors were involved, addition of vermicompost to soil at four ratios: control(100 wt%(weight percentage) soil); 10 wt% vermicompost+90% soil; 20 wt% vermicompost+80 wt% soil; 30 wt% vermicompost+70 wt% soil weight percentage, and treatment of water stress at three levels including 75, 50, and 25% of field capacity. The results showed that vermicompost had a significant effect on all traits under stress and non-stress conditions. Application of vermicompost in soil, especially at the levels of 20 and 30 wt% significantly increased all studied traits under non-stress conditions. Under moderate stress conditions, vermicompost at 30 wt% treatment resulted in a significant increase in the photosynthetic pigments, CO_2 assimilation rate, internal leaf CO_2 concentration, transpiration, the maximal quantum yield of photosystem II(PSII) photochemistry(F_v/F_m), concentrations of Ca and K in root and leaf tissues, proline and soluble protein contents in root tissues. Peroxidase(POX) and catalase(CAT) enzyme activities decreased significantly with increasing proportions of vermicompost, but the activity of superoxide dismutase was not significantly different. In conclusion, the above results showed that vermicompost fertilizer had a positive effect on physiological, biochemical, and photosynthetic responses of chickpea under non-stress and moderate stress conditions, but no positive effect was determined under severe water stress. | Saeed Reza Hosseinzadeh Hamzeh Amiri Ahmad Ismaili | 2018 | Journal of Integrative Agriculture2018，17，11： | 9 |
| 2 | Heat Transfer and Energy Analysis of a Pusher Type Reheating Furnace Using Oxygen Enhanced Air for Combustion显示文摘Oxy-fuel firing is more energy efficient and environmental friendly than conventional air-fuel firing and its application to reheating furnaces has begun since 1990s.A computational method was presented to predict the steady heat transfer to the billets and temperature distribution in a continuous pusher type reheating furnace in which combustion air was enhanced by oxygen.Radiation heat flux calculated from the radiation heat exchange within the furnace was modeled using the FVM considering the effects of furnace walls and billets.Energy consumption per ton of steel,production rate and thermal efficiency of furnace,and trend of NOx emission in various levels of oxygen enrichment were investigated by comparing with baseline furnace(21% of O2 in air).The results showed that the best range of oxygen enrichments was between 21% and 45% by volume,as the higher slope of flame temperature and production increase occur in this range.The reduction of energy consumption can be obtained up to 18% per ton of steel for oxygen enrichment of 60% by volume. | Hamzeh Jafar Karimi Mohammad Hassan Saidi | 2010 | Journal of Iron and Steel Research(International)2010，17，4： | 7 |
| 3 | Effects of probiotic supplementation on abdominal pain severity in pediatric patients with irritable bowel syndrome:a systematic review and meta-analysis of randomized clinical trials显示文摘Background Probiotic supplementation has been used to alleviate abdominal pain in children and adolescents with irritable bowel syndrome(IBS),but the evidence is not compelling.Thus,a systematic review and meta-analysis of randomized clinical trials(RCTs)were performed to investigate the effects of probiotic supplementation on abdominal pain in pediatric patients with IBS.Methods PubMed/MEDLINE,Web of Science,Scopus,Cochrane Library,and Embase were the available databases searched to find relevant randomized clinical trials up to April 2021.The effect size was expressed as weighted mean differenee(WMD)and 95% confidence interval(CI).Results Seven RCTs with 441 participants were included,from which the meta-analysis demonstrated that probiotic supplementation has a significant effect on reducing abdominal pain in pediatric patients with IBS(WMD=-2.36:95%CI-4.12 to-0.60;P=0.009).Although our study involved children and adolescents(≤18 years),the effects of probiotic supplementation seem to be more potent in patients under 10 years old(WMD=-2.55;95%CI-2.84 to -2.27)compared to patients aged 10-18 years(WMD=-1.70;95%CI-2.18 to -1.22).The length of supplementation longer than four weeks was more effective(WMD=-2.43;95%CI-2.76 to -2.09).Conclusion Probiotic supplementation can reduce abdominal pain in pediatric patients with IBS. | Somayeh Fatahi Amirhossein Hosseini Mohammad Hassan Sohouli Aliakbar Sayyari Katayoun Khatami Zahra Fazeli Farsani Hamzeh Amiri Naghi Dara Ivan G.O.de Souza Heitor O.Santos | 2022 | World Journal of Pediatrics2022，18，5： | 5 |
| 4 | 利用井筒稳定性分析确定砂岩安全钻井液密度窗口显示文摘以伊朗西南部某油田Asmari组砂岩储集层为研究对象,研究其中一口垂直井的井筒稳定性,利用FLAC3D软件,根据钻遇地层地质力学特征建立井筒的有限体积模型,监测井壁岩石塑性状态的形成以确定砂岩层安全钻井液密度的上限值和下限值。评估了岩石强度特性、井筒周围主要地应力和孔隙压力对该井安全钻井液密度窗口的影响,敏感性分析结果表明,井壁岩石内聚力和内摩擦角的减小会导致安全钻井液密度窗口大幅变窄;孔隙压力和最大水平应力与最小水平应力之比的减小则会使安全钻井液密度窗口显著增大。此模型便于量化安全钻井液密度窗口的变化,可作为一种油气井钻井方案设计和监测工具。 | DARVISHPOUR Ayoub SEIFABAD Masoud Cheraghi WOOD David Anthony GHORBANI Hamzeh | 2019 | 石油勘探与开发2019，46，5： | 5 |

| 7 | Role of bevacizumab intraocular injection in the management of neovascular glaucoma显示文摘AIM:To assess the long-term effects of intraocular bevacizumab(Avastin)injections as an adjunctive drug to manage patients with neovascular glaucoma(NVG).METHODS:A retrospective study was conducted consisting of 34 eyes with secondary NVG caused by proliferative diabetic retinopathy(n=25),ischemic central retinal vein occlusion(n=8),and retinal ischemia resulting from persistent detachment(n=1)were managed by intraocular injections of bevacizumab(1.25 mg/0.05 m L),in addition to other treatments.The main outcome measure was the change in the degree of iris neovascularization.Secondary outcomes included intraocular pressure and the number of additional interventions or antiglaucoma medications administered after injection.RESULTS:All patients were followed-up for at least 12 mo.At the last follow-up,complete regression of rubeosis irides was detectable in 13(38.2%)eyes and incomplete regression in 21 eyes(61.8%).The mean intraocular pressure was 45.32±7.185 mm Hg at baseline and significantly decreased to 26.15±5.679 mm Hg at the last follow-up visit(P=0.000005).Patients received an average of 4.97 injections.As additional treatments,12 eyes(35%)received laser photocoagulation and 6 eyes(18%)underwent retinocryopexy.No further treatment was needed in 16 eyes(47.1%).CONCLUSION:Intravitreal bevacizumab injection can have a favorable effect in controlling intraocular pressure and pain control in patients with NVG because it decreases the angiogenesis and helps to augment the results of conventional procedures.The primary cause of retinal ischemia should be always targeted. | Fawaz Al Sarireh Hamzeh Mohammad Alrawashdeh Khalid Al Zubi Khalil Al Salem | 2021 | International Journal of Ophthalmology(English edition)2021，14，6： | 4 |
| 8 | The effects of transcranial direct current stimulation on gait in patients with Parkinson’s disease:a systematic review显示文摘Background:Gait problems are an important symptom in Parkinson’s disease(PD),a progressive neurodegenerative disease.Transcranial direct current stimulation(tDCS)is a neuromodulatory intervention that can modulate cortical excitability of the gait-related regions.Despite an increasing number of gait-related tDCS studies in PD,the efficacy of this technique for improving gait has not been systematically investigated yet.Here,we aimed to systematically explore the effects of tDCS on gait in PD,based on available experimental studies.Methods:Using the PRISMA(Preferred Reporting Items for Systematic Reviews and Meta-Analyses)approach,PubMed,Web of Science,Scopus,and PEDro databases were searched for randomized clinical trials assessing the effect of tDCS on gait in patients with PD.Results:Eighteen studies were included in this systematic review.Overall,tDCS targeting the motor cortex and supplementary motor area bilaterally seems to be promising for gait rehabilitation in PD.Studies of tDCS targeting the dorosolateral prefrontal cortex or cerebellum showed more heterogeneous results.More studies are needed to systematically compare the efficacy of different tDCS protocols,including protocols applying tDCS alone and/or in combination with conventional gait rehabilitation treatment in PD.Conclusions:tDCS is a promising intervention approach to improving gait in PD.Anodal tDCS over the motor areas has shown a positive effect on gait,but stimulation of other areas is less promising.However,the heterogeneities of methods and results have made it difficult to draw firm conclusions.Therefore,systematic explorations of tDCS protocols are required to optimize the efficacy. | Fateme Pol Mohammad Ali Salehinejad Hamzeh Baharlouei Michael A.Nitsche | 2021 | Translational Neurodegeneration2021，10，2： | 4 |
| 9 | Life Cycle Assessment modeling of milk production in Iran显示文摘Livestock units are known as one of the most influential sectors in the environment pollution.Therefore,the aim of this study was to investigate the environmental impacts of milk production in Guilan province of Iran through Life Cycle Assessment(LCA)methodology.The primary data were collected from 45 units of milk production through a field survey with the help of a structured questionnaire.The reliability was assessed using Cronbach’s alpha coefficient and was estimated an acceptable value of 0.91.The consumption of resources and emissions were allocated to a functional unit(FU)of one ton of milk.Impacts of emissions in five impact categories of global warming,acidification,eutrophication,photochemical oxidation and depletion of resources were investigated.The results showed that the characterization index for these impact categories were 1831 kg CO2 eq,7.97 kg SO2 eq,3.42 kg PO4^-3 eq,0.21 kg C2H4 eq and 838.39 MJ,respectively.Final indices for these impact categories were calculated as 0.24,0.28,0.076,0.017 and 0.046,respectively.Environmental index(EcoX)and resources depletion index(RDI)were obtained 0.61 and 0.04,respectively.In this study,the highest potential for environmental impacts of production revealed for acidification and followed by global warming impact category. | Hamzeh Soltanali Bagher Emadi Abbas Rohani Mehdi Khojastehpour Amin Nikkhah | 2015 | Information Processing in Agriculture2015，2，2： | 4 |

| 11 | Role of endoscopic ultrasound in liver disease: Where do we stand in 2017?显示文摘Endoscopic ultrasound(EUS) was first introduced into medical practice in 1980 s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, is now having increasing therapeutic role as well. We provide a review of the application of EUS in the diagnostic and therapeutic aspects of liver disease. We also look at the evolving future research on the role of EUS in liver diseases. | Hamzeh A Saraireh Mohammad Bilal Shailendra Singh | 2017 | World Journal of Hepatology2017，9，24： | 4 |
| 12 | A tri-level programming model for attack-resilient control of power grids显示文摘The significance of modern power grids is acknowledged every time there is a major threat. This paper proposes the novel approaches to aid power system planner to improve power grid resilience by making appropriate hardening strategies against man-made attack or natural hazards. The vulnerability indices are introduced, which return the most vulnerable component in the system based on a tri-level defender-attacker-operator(DAO) interdiction problem which solves iteratively. The output of DAO is the set of hardening strategies that optimally allocated along the network to mitigate the impact of the worst-case damages. By repeating DAO problem based on the proposed algorithm, the various crafted attack is imposed on the system, and the defender's behavior demonstrates how an element is vulnerable to threats. The WSCC 9-bus, IEEE 24-bus, and IEEE 118-bus systems are employed to evaluate the model performance.The counter-intuitive results are proven by the proposed robust hardening strategy, which shows how the hardening strategy should be allocated to improve power network resilience against threats. | Hamzeh DAVARIKIA Masoud BARATI | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，5： | 4 |

| 14 | The Effect of Variable Stator on Performance of a Highly Loaded Tandem Axial Flow Compressor Stage显示文摘Increasing the aerodynamic load on compressor blades helps to obtain a higher pressure ratio in lower rotational speeds.Considering the high aerodynamic load effects and structural concerns in the design process,it is possible to obtain higher pressure ratios compared to conventional compressors.However,it must be noted that imposing higher aerodynamic loads results in higher loss coefficients and deteriorates the overall performance.To avoid the loss increase,the boundary layer quality must be studied carefully over the blade suction surface.Employment of advanced shaped airfoils(like CDAs),slotted blades or other boundary layer control methods has helped the designers to use higher aerodynamic loads on compressor blades.Tandem cascade is a passive boundary layer control method,which is based on using the flow momentum to control the boundary layer on the suction surface and also to avoid the probable separation caused by higher aerodynamic loads.In fact,the front pressure side flow momentum helps to compensate the positive pressure gradient over the aft blade's suction side.Also,in comparison to the single blade stators,tandem variable stators have more degrees of freedom,and this issue increases the possibility of finding enhanced conditions in the compressor off-design performance.In the current study,a 3D design procedure for an axial flow tandem compressor stage has been applied to design a highly loaded stage.Following,this design is numerically investigated using a CFD code and the stage characteristic map is reported.Also,the effect of various stator stagger angles on the compressor performance and especially on the compressor surge margin has been discussed.To validate the CFD method,another known compressor stage is presented and its performance is numerically investigated and the results are compared with available experimental results. | Hamzeh Eshraghi Masoud Boroomand Abolghasem M.Tousi Mohammad Toude Fallah Ali Mohammadi | 2016 | Journal of Thermal Science2016，25，3： | 3 |

| 17 | Lens thickness assessment : anterior segment optical coherence tomography versus A-scan ultrasonography显示文摘AIM: To assess lens thickness measurements with anterior segment-optical coherence tomography(AS-OCT)in comparison with A-scan ultrasonography(A-scan US).·METHODS: There were 218 adult subjects(218 eyes)aged 59.2 ±9.2y enrolled in this prospective cross-sectional study. Forty-three eyes had open angles and 175 eyes had narrow angles. Routine ophthalmic exam was performed and nuclear opacity was graded using the Lens Opacities Classification System Ⅲ(LOCS Ⅲ). Lens thickness was measured by AS-OCT(Visante OCT, Carl Zeiss Meditec, Dublin, CA, USA). The highest quality image was selected for each eye and lens thickness was calculated using Image J software. Lens thickness was also measured by A-scan US.·RESULTS: Interclass correlations showed a value of99.7% for intra-visit measurements and 95.3% for inter-visit measurements. The mean lens thickness measured by AS-OCT was not significantly different from that of A-scan US(4.861 ±0.404 vs 4.866 ±0.351 mm, P =0.74).Lens thickness values obtained from the two instruments were highly correlated overall(Pearson correlation coefficient =0.81,P <0.001), and in all LOCS Ⅲ specific subgroups except in grade 5 of nuclear opacity. Bland-Altman analysis revealed a 95% limit of agreement from-0.45 to 0.46 mm. Lens thickness difference between the two instruments became smaller as the lens thickness increased and AS-OCT yielded smaller values than A-scan US in thicker lens(β=-0.29, P <0.001)· CONCLUSION: AS-OCT-derived lens thickness measurement is valid and comparable to the results obtained by A-scan US. It can be used as a reliable noncontact method for measuring lens thickness in adults with or without significant cataract. | Nikoo Hamzeh Sasan Moghimi Golshan Latifi Massood Mohammadi Nassim Khatibi Shan C.Lin | 2015 | International Journal of Ophthalmology(English edition)2015，8，6： | 2 |
| 18 | Effect of Low-Pressure Nitrogen DC Plasma Treatment on the Surface Properties of Biaxially Oriented Polypropylene, Poly (Methyl Methacrylate) and Polyvinyl Chloride Films显示文摘In this study, commercial biaxially oriented polypropylene (BOPP), polyvinyl chloride (PVC) and poly (methyl methacrylate) (PMMA) films were treated with nitrogen plasma over different exposure times in a Pyrex tube surrounded by a DC variable magnetic field. The chemical changes that appeared on the surface of the samples were investigated using Fourier transform infrared (FT-IR) spectroscopy and attenuated total reflectance Fourier transform infrared (ATR- FTIR) spectroscopy after treatment for 2 min, 4 min and 6 min in a nitrogen plasma chamber. Effects of the plasma treatment on the surface topographies and contact angles of the untreated and plasma treated films were also analyzed by atomic force microscopy (AFM) and a contact angle measuring system. The results show that the plasma treated films become more hydrophilic with an enhanced wettability due to the formation of some new polar groups on the surface of the treated films. Moreover, at higher exposure times, the total surface energy in all treated films increased while a reduction in contact angle occurred. The behavior of surface roughness in each sample was completely different at higher exposure times. | S. Hamideh MORTAZAVI Mahmood GHORANNEVISS Soheil PILEHVAR Sina ESMAEILI Shamim ZARGHAM S.

| 19 | Tunneling in submicron CMOS single-photon avalanche diodes显示文摘Tunneling is studied in two main single-photon avalanche diode(SPAD) topologies,which are n-tub guard ring(NTGR) and p-tub guard ring(PTGR).Device simulation,I-V measurements,and dark count calculations and measurements demonstrate that tunneling is the main source of noise in NTGR,but it is less dominant in PTGR SPADs.All structures are characterized with respect to dark noise,photon detection probability,timing jitter,afterpulsing probability,and breakdown voltage.Noise performance is disturbed because of tunneling,whereas jitter performance is disturbed because of the short diffusion time of photo-generated minority carriers in NTGR SPADs.The maximum photon detection probability is enhanced because of an improvement in absorption thickness. | Mohammad Azim Karami Armin Amiri-Sani Mohammad Hamzeh Ghormishi | 2014 | Chinese Optics Letters2014，12，1： | 2 |
| 20 | Comparison of accuracy and computational performance between the machine learning algorithms for rate of penetration in directional drilling well显示文摘Oil and gas reservoirs are of the main assets of countries possessing them.Production from these reservoirs is one of the main concerns of engineers,which can be achieved by drilling oil and gas reservoirs.Construction of hydrocarbon wells is one of the most expensive operations in the oil industry.One of the most important parameters affecting drilling cost is the rate of penetration(ROP).This paper predicts the rate of penetration using artificial intelligence and hybrid models on Kaboud oil field well#7 in the directional stage.In this study,different models were constructed through various approaches based on 1878 dataset obtained from drilling operation in the well#7.Then,the accuracy of the constructed models was compared with each other.It was found that the MLP-ABC algorithm predicts the rate of penetration more accurately,by far,as compared with other methods.The MLP-ABC algorithm achieves impressive ROP prediction accuracy(RMSE=0.007211 m/h;AAPD=0.1871%;R^(2)=1.000 for the testing subset).Consequently,it can be concluded that this method is applicable to predict the drilling rate in that oilfield. | Omid Hazbeh Saeed Khezerloo-ye Aghdam Hamzeh Ghorbani Nima Mohamadian Mehdi Ahmadi Alvar Jamshid Moghadasi | 2021 | Petroleum Research2021，6，3： | 2 |
