| 1 | Solvent extraction and separation of light rare earth elements (La, Pr and Nd) in the presence of lactic acid as a complexing agent by Cyanex 272 in kerosene and the effect of citric acid,acetic acid and Titriplex Ⅲ as auxiliary agents显示文摘At present, the use of rare earth elements(REEs) has become an inevitable necessity in many modern industries. In general, liquid extraction is the best commercial method for extracting REEs due to its ability to control high volumes of liquids with electrical load. With the aim of improving a separation technology that would be superior to the existing extraction systems, the extraction behaviors of La(Ⅲ),Pr(Ⅲ), and Nd(Ⅲ) from an HCI medium with Cyanex 272 in the presence of the complexing agent lactic acid(HLac) and auxiliary agents citric acid(H_3 Cit), acetic acid(HAc), and Titriplex Ⅲ have been reported.The effect of pH and lactic acid concentration has been examined. The use of lactic acid as a complexing agent leading to a high extraction of REEs with Cyanex 272 at pH = 5 was compared with systems without lactic acid. The results show that the use of acetic acid along with lactic acid leads to an increase in the extraction percentage of LREEs. While use of citric acid and Titriplex Ⅲ reduces the extraction percentage of LREEs. Finally, the presence of Titriplex Ⅲ together with lactic acid could lead to an increase in the separation factor of Pr and Nd. | Eslam Kashi Razieh Habibpour Hesamoddin Gorzin Armin Maleki | 2018 | Journal of Rare Earths2018，36，3： | 12 |

| 3 | Laying hen performance,egg quality improved and yolk 5-methyltetrahydrofolate content increased by dietary supplementation of folic acid显示文摘This study was performed to evaluate the effect of folic acid(FA) on performance, egg quality and yolk5-methyltetrahydrofolate(5-MTHF) content. A total of 384 Hy-line W36 strain hens from 52 to 58 weeks of age were randomly assigned to 4 groups, and each group received one of following dietary treatments:0, 5.10 and 15 mg FA/kg diet. A completely randomized design was used. Egg production percentage, egg mass and egg weight were increased significantly(P < 0.05) and feed conversion ratio(FCR) was reduced significantly(P < 0.05) by increasing FA content in diets. No significant differences were detected among treatments on egg quality except for shell thickness. The dietary supplementations of laying hens diets with FA significantly increased yolk 5-MTHF content(P = 0.02). Overall, these data demonstrate that dietary supplementation with FA raised 5-MTHF content of yolk and productivity of egg production in laying hens. | Sattar Bagheri Hossein Janmohammadi Ramin Maleki Alireza Ostadrahimi Ruhollah Kianfar | 2019 | Animal Nutrition2019，，2： | 9 |

Intermediate antibacterial activity was exhibited by G.tricornutum and Vi.pseudo negundo against some of the studied strains with 7-20 mm and 7-13 mm of diameters,respectively. Noteworthy,out of 9 studied strains;6 and 2 of them were resistant to the G.tricornutum and Vi. pseudo negundo extracts,respectively.The S.officinalis and Va.pyramidata,however,showed no antibacterial activity against the studied strains.Conclusions:The Q.brantii,P.harmala,Z. spina-christi and O.decumbens extracts were shown to possess strong antibacterial activity against methicillin and cefixime resistant S.aureus strains and can be considered as the promising natural antibiotics for treating the studied strains. | Morteza Shojaei Moghadam Susan Maleki Esmaeil Darabpour Hossein Motamedi Seyyed Mansour Seyyed Nejad | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，4： | 7 |
| 5 | Coal pillar mechanics of violent failure in U.S. Mines显示文摘This paper seeks to enhance the understanding that the horizontal stresses build up and release during coal pillar loading and unloading(post-failure) drawing upon three decades of observations, geomechanical monitoring and numerical modeling in bump-prone U.S. mines. The focus is on induced horizontal stress in mine pillars and surrounding strata as highly stressed pillars punch into the roof and floor, causing shear failure and buckling of strata; under stiff stratigraphic units of some western US mines, these events could be accompanied by violent failure of pillar cores. Pillar punching eventually results in tensile stresses at the base of the pillar, facilitating transition into the post-failure regime; this transition will be nonviolent if certain conditions are met, notably the presence of interbedded mudstones with low shear strength properties and proper mine designs for controlling seismicity and dynamic loads. The study clearly shows high confining stress build-up in coal pillars resulting in up to twice higher peak vertical stress and high strain energy accumulations in some western US mines in comparison with peak stresses predicted using common empirical pillar design methods. It is the unstable release of this strain energy that can cause significant damage resulting from pillar dilation and ground movements. These forces are much greater than the capacity of most common internal support systems, resulting in horizontal stressinduced roof falls locally, in mines under unremarkable far-field horizontal stress. Attention should be placed on pillar designs as increasing support density may prove to be ineffective. This mechanism is analyzed using field measurements and generic finite-difference stress analyses. The study confirms the higher load carrying capacity of confinement-controlled coal seams in comparison with structurally controlled coal seams. Such significant differences in confining stresses are not taken into account when estimating peak pillar strength using most common empirical techniques such as those proposed by Bieniawski and Salamon. While using lower pillar strength estimates may be considered conservative,it underestimates the actual capacity of pillars in accumulating much higher stress and strain energies,misleading the designer and inadvertently diminishing mine safety. The role of induced horizontal stress in mine pillars and surrounding strata is emphasized in coal pillar mechanics of violent failure. The triggering mechanism for the violent events is sudden loss of pillar confinement due to dynamic loading resulting from failure of overlying stiff and strong strata. Evidence of such mechanism is noted in the field by observed red-dust at the coal-rock interfaces at the location of coal bumps and irregular, periodic caving in room-and-pillar mines quantified through direct pressure measurements in the gob. | Maleki Hamid | 2017 | International Journal of Mining Science and Technology2017，27，3： | 7 |
| 6 | 提高复合挤压铸造Al/Al-Cu双金属宏观复合材料界面结合的新方法(英文)显示文摘开发一种简便的提高复合挤压铸造Al/Al-4.5wt.%Cu双金属复合材料界面结合的新方法,并研究该方法对此双金属的显微组织和力学性能的影响。在挤压铸造Al-4.5wt.%Cu的内表面机加工一种特殊的同心槽图案,利用ProCAST和ANSYS软件对双金属构件界面区域的传热、凝固和产生的应力分布进行数值模拟,并进行实验验证。模拟结果表明,表面沟槽尖端完全熔化,沿界面产生较大的局部应力梯度场,这会导致插入界面的氧化铝层破裂,促进双金属组分的扩散结合。显微组织表征证实双金属界面存在明显的过渡区。通过加工表面图案,双金属的平均过渡区厚度和抗拉强度分别显著增加到375μm和54MPa。因此,该方法是一种经济可行的复合挤压铸造铝-铝宏观复合双金属的方法,不需要提前对固体镶块进行任何成本和时间密集型的化学或涂层处理。 | Mohammad Hossein BABAEE Ali MALEKI Behzad NIROUMAND | 2019 | Transactions of Nonferrous Metals Society of China2019，29，6： | 5 |
| 7 | Electronical and thermoelectric properties of half-Heusler ZrNiPb under pressure in bulk and nanosheet structures for energy conversion显示文摘The pressure dependence of structural,electronic and thermoelectric properties of half-Heusler ZrNiPb was investigated in the bulk and nanosheet structures.In order to obtain the accurate results,the full-potential(linearized) augmented plane-wave(FP(L)APW)calculations were performed with the Perdew-BurkeErnzerhof generalized gradient approximation(PBE-GGA)and modified Becke-Johnson(mBJ) plus spin-orbit coupling(SOC).Obtained band gap values are in close agreement with the experimental results(<0.5 eV).The variations of the thermoelectric properties of the ZrNiPb were studied under different temperatures,carrier concentrations and the hydrostatic pressures.The results show that the hydrostatic pressure decreases the lattice constant value.The band structure calculations display that the band gap increases with pressure for the bulk state and it is 0 for the nanosheet of ZrNiPb [010].The highest value of figure of merit(ZT)=0.95 is found at 9.378 GPa at a carrier concentration of n=1 × 10^18 cm^-3 at 250 K for p-type of ZrNiPb. | Hossein Asghar Rahnamaye Aliabad Zahra Nodehi Behrooz Maleki Azam Abareshi | 2019 | Rare Metals2019，38，11： | 5 |
| 8 | Effect of channel shape on selection of time marching scheme in the discontinuous Galerkin method for 1-D open channel flow显示文摘One-dimensional open channel flows are simulated using the discontinuous Galerkin finite element method. Three different explicit time marching schemes, including multistep/multistage schemes, are evaluated for different channel shapes for accuracy and efficiency. The Forward Euler, second-order Adam-Bashforth(multistep), and second-order total variation diminishing(TVD) Runge-Kutta(multistage) time marching schemes are utilized. The role of monotonized central, minmod, and zero TVD slope limiters for each of the time marching scheme is investigated. The numerical flux is approximated using HLL function. The accuracy and robustness of different time marching schemes are evaluated for steady and unsteady flows using analytical and measured data. The unsteady flows include dam break tests with wet and dry beds downstream of the dam in prismatic(rectangular, trapezoidal, triangular, and parabolic cross-sections) and non-prismatic(natural river) channels. The steady flow test involves simulation of hydraulic jump in a diverging rectangular channel. The various schemes are evaluated by comparing accuracy using statistical measures and efficiency using maximum possible time step size as well as CPU runtime. The second-order Adam-Bashforth time marching scheme is found to have the best accuracy and efficiency among the time stepping schemes tested. | SAFARZADEH MALEKI Farzam KHAN Abdul A. | 2015 | Journal of Hydrodynamics2015，27，3： | 4 |
| 9 | High-performance self-assembly MnCo2O4 nanosheets for asymmetric supercapacitors显示文摘In this study,MnCo2O4 nanosheets were proposed to be utilized as an electrode material for supercapacitors.A two-step hydrothermal method with post-annealing treatment was employed in preparation of the nanostructures.MnCo2O4 electrode delivered a high specific capacitance of 2000 F g^-1 at 0.5 A g^-1,remarkable high-rate capability of 1150 F g^-1 at 20 A g^-1,and an excellent cycling stability of 92.3%at 5 A g^-1 after 5000 cycles.It is found that a three-electrode supercapacitor based on MnCo2O4 exhibits a promising electrochemical performance,better than the other similar materials,benefited from the synergistic effects of MnCo2O4 nanosheets.In fact,the self-assembly of nanosheets structure with high specific surface area and mesoporous structure can potentially enhance the electrochemical performance of supercapacitors. | Jianwei Li Dongbin Xiong Linzhe Wang Maleki Kheimeh Sari Hirbod Xifei Li | 2019 | Journal of Energy Chemistry2019，28，10： | 4 |

| 11 | Serum immunoglobulin A concentration is a reliable biomarker for liver fibrosis in non-alcoholic fatty liver disease显示文摘AIM:To evaluate the diagnostic accuracy of serum Immunoglobulin A(IgA)for differentiating early stage nonalcoholic fatty liver disease(NAFLD)from nonalcoholic steatohepatitis(NASH).METHODS:All cases had fatty liver change confirmed by ultrasound and aminotransferases of at least twice the normal level.Clinical and biochemical data,including serum IgA,were obtained from 50 histologically proven NAFLD cases and 54 healthy controls.Fasting whole blood samples were obtained from the study population.Immunoturbidimetric methods were used to measure the IgA levels.All NAFLD cases were hospitalized for liver biopsy.Liver specimens were examined for steatosis,steatohepatitis and fibrosis within hepatocytes.Patients were categorized into two groups:NASH and non-NASH.Variables were compared within cases(NASH vs non-NASH)and controls.Cut-off values of serum IgA were evaluated using analysis of receiver operating characteristic(ROC curves).Associations between the variables were tested using calculations of correlation coefficients.Statistical significances were assigned to P values<0.05.RESULTS:The extent of liver fibrosis correlated positively with IgA levels.Subjects with no fibrosis in their liver biopsies had a lower IgA level(301.5±91.2 mg/dL)than subjects with any degree of fibrosis(388.8±140.8 mg/dL),(P=0.01).IgA levels were higher in NASH cases,and its value was significantly higher for higher degrees of fibrosis.Patients with perisinusoidal or pericellular fibrosis had significantly higher levels of IgA(403.5±133.9 mg/dL,418.2±129.5 mg/dL)compared to those without it(301.8±94.9 mg/dL,297.7±91.5 mg/dL),respectively.No significant correlation was found between steatosis grade and serum IgA levels.Based on ROC analysis,the best predictive IgA cutoff value for detecting liver fibrosis was 360mg/dL(61%sensitivity,81%specificity).CONCLUSION:The serum IgA level is useful to evaluate the severity of liver fibrosis and can be used serially for evaluation and follow-up of NAFLD cases. | Iradj Maleki Mahmood Reza Aminafshari Tarang Taghvaei Vahid Hosseini Alireza Rafiei Zhila Torabizadeh Maryam Barzin Elahe Orang | 2014 | World Journal of Gastroenterology2014，20，35： | 4 |
| 12 | Midline synovial and ganglion cysts causing neurogenic claudication显示文摘Typically situated posterolateral in the spinal canal, intraspinal facet cysts often cause radicular symptoms. Rarely, the midline location of these synovial or ganglion cysts may cause thecal sac compression leading to neurogenic claudication or cauda equina syndrome. This article summarizes the clinical presentation, radiographic appearance, and management of three intraspinal, midline facet cysts. Three patients with symptomatic midline intraspinal facet cysts were retrospectively reviewed. Documented clinical visits, operative notes, histopathology reports, and imaging findings were investigated for each patient. One patient presented with neurogenic claudication while two patients developed partial, subacute cauda equina syndrome. All 3 patients initially responded favorably to lumbar decompression and midline cyst resection; however, one patient required surgical stabilization 8 mo later. Following the three case presentations, we performed a thorough literature search in order to identify articles describing intraspinal cystic lesions in lateral or midline locations. Midline intraspinal facet cysts represent an uncommon cause of lumbar stenosis and thecal sac compression. Such entities should enter the differential diagnosis of midline posterior cystic lesions. Midline cysts causing thecal sac compression respond favorably to lumbar surgical decompression and cyst resection. Though laminectomy is a commonly performed operation, stabilization may be required in cases of spondylolisthesis or instability. | Jonathan Pindrik Mohamed Macki Mohamad Bydon Zahra Maleki Ali Bydon | 2013 | World Journal of Clinical Cases2013，1，9： | 3 |

| 16 | Synthesis of a copolymer carrier for anticancer drug luteolin for targeting human breast cancer cells显示文摘OBJECTIVE: To focus a new chemoprevention approach that uses nanotechnology to deliver luteolin to human breast cancer cells(MCF-7), and its underlying mechanism.METHODS: Water-soluble copolymer-encapsulated nanoparticle-luteolin(CENL) was formulated using the hydrophobic drug luteolin. The ability to load and release he anticancer drug into/from the synthesized hyperbranched polyester was evaluated by high-performance liquid chromatography.The successful synthesis of CENL was supported by analytical techniques including fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, gel permeation chromatography,and dynamic light scattering. Cell viability was measured using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide color method. Reactive oxygen species(ROS) were measured using a dichlorofluorescein probe and intracellular calcium(Cai2+) was evaluated with a flu3-AM probe.RESULTS: The results showed that the drug delivery system is stable and that the loading capacity is high. Treatment with nanoparticles containing luteolin and free luteolin resulted in cell death in breast cancer cells at high concentrations (IC50(33 ± 4) and(48 ± 6) μM, respectively)At high concentrations,CENL reduced cell viability and increased ROS and Cai2+ production.CONCLUSION: Our results demonstrate that CENL has potential for human breast cancer treatment. | Mahin Maleki Ali Aidy Elahe Karimi Shaahin Shahbazi Nader Safarian Naser Abbasi | 2019 | Journal of Traditional Chinese Medicine2019，39，4： | 2 |
| 17 | Analysis of factors affecting diagonal tension and compression capacity of corner joints in furniture frames fabricated with dovetail key显示文摘This study was conducted to analyze the effect of joint type, and numbers and types of dovetail keys on diagonal tension and compression performance of corner joints in a furniture frame. Joint members were cut from white fir lumber. Butted and mitered joints were constructed with one and two dovetail key(s) with butterfly and H shapes. Joints were glued by polyvinyl acetate (PVAc) and cynoacrylate (CA). Compression capacity of joints was higher than diagonal tension. Mitered joints were stronger than butted ones. Butterfly dovetail keys were superior to H shape keys. Double keys performed better than single key. Experimental joints glued with PVAc were stronger than those glued with CA glue and control specimens. In terms of strength, butterfly dovetailed joints were comparable with doweled joints. | Mosayeb Dalvand Ghanbar Ebrahimi Akbar Rostampour Haftkhani Sadegh Maleki | 2013 | Journal of Forestry Research2013，24，1： | 2 |
| 18 | 1-D coupled non-equilibrium sediment transport modeling for unsteady flows in the discontinuous Galerkin framework显示文摘A high-resolution,1-D numerical model has been developed in the discontinuous Galerkin framework to simulate 1-D flow behavior,sediment transport,and morphological evaluation under unsteady flow conditions.The flow and sediment concentration variables are computed based on the one-dimensional shallow water flow equations,while empirical equations are used for entrainment and deposition processes.The sediment transport model includes the bed load and suspended load components.New formulations for Harten-Lax-van Leer(HLL) and Harten-Lax-van Contact(HLLC) are presented for shallow water flow equations that include the bed load and suspended load fluxes.The computational results for the flow and morphological changes after two dam break events are compared with the physical model tests.Results show that the modified HLL and HLLC formulations are robust and can accurately predict morphological changes in highly unsteady flows. | Farzam Safarzadeh MALEKI Abdul A.KHAN | 2016 | Journal of Hydrodynamics2016，28，4： | 2 |
