| 4 | Is it time to replace propranolol with carvedilol for portal hypertension?显示文摘Beta-adrenergic receptor antagonists(β-blockers) have been well established for use in portal hypertension for more than three decades. Different Non-selective β-blockers like propranolol, nadolol, timolol, atenolol, metoprolol and carvedilol have been in clinical practice in patients with cirrhosis. Carvedilol has proven 2-4 times more potent than propranolol as a beta-receptor blocker in trials conducted testing its efficacy for heart failure. Whether the same effect extends to its potency in the reduction of portal venous pressures is a topic of on-going debate. The aim of this review is to compare the hemodynamic and clinical effects of carvedilol with propranolol, and attempt assess whether carvedilol can be used instead of propranolol in patients with cirrhosis. Carvedilol is a promising agent among the beta blockers of recent time that has shown significant effects in portal hypertension hemodynamics. It has also demonstrated an effective profile in its clinical application specifically for the prevention of variceal bleeding. Carvedilol has more potent desired physiological effects when compared to Propranolol. However, it is uncertain at the present juncture whether the improvement in hemodynamics also translates into a decreased rate of disease progression and complications when compared to propranolol. Currently Carvedilol shows promise as a therapy for portal hypertension but more clinical trials need to be carried out before we can consider it as a superior option and a replacement for propranolol. | Shahab Abid Saadat Ali Muhammad Asif Baig Anam Akbar Waheed | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 13 |
| 5 | Health risks associated with heavy metals in the drinking water of Swat,northern Pakistan显示文摘The concentrations of heavy metals such as Cd, Cr, Cu, Mn, Ni, Pb and Zn were investigated in drinking water sources(surface and groundwater) collected from Swat valley, Khyber Pakhtunkhwa, Pakistan. The potential health risks of heavy metals to the local population and their possible source apportionment were also studied. Heavy metal concentrations were analysed using atomic absorption spectrometer and compared with permissible limits set by Pakistan Environmental Protection Agency and World Health Organization. The concentrations of Cd, Cr, Ni and Pb were higher than their respective permissible limits, while Cu, Mn and Zn concentrations were observed within their respective limits. Health risk indicators such as chronic daily intake(CDI) and health risk index(HRI) were calculated for adults and children separately. CDIs and HRIs of heavy metals were found in the order of Cr > Mn >Ni > Zn > Cd > Cu > Pb and Cd > Ni > Mn > Cr > Cu > Pb > Zn, respectively. HRIs of selected heavy metals in the drinking water were less than 1, indicating no health risk to the local people. Multivariate and univariate statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination with heavy metals in the study area. | Kifayatullah Khan Yonglong Lu Hizbullah Khan Shahida Zakir Ihsanullah Sardar Khan Akbar Ali Khan Luo Wei Tieyu Wang | 2013 | Journal of Environmental Sciences2013，25，10： | 12 |
| 6 | Scour and flow field around a spur dike in a 90° bend显示文摘Spur dike is an important element in river training that creates rapid variations in flow field, sediment transport and bed topography. The mechanism of flow and sediment transport in a channel bend is very complex, especially when a spur dike is constructed in a bend. Most of previous investigations on flow behavior and scour around spur dike were carried out in straight channels. In this paper results of experiments on flow field and scour around a spur dike in a 90 degree channel bend are presented. Sand with uniform grain size was used as the bed material. Experiments were conducted for different locations and different lengths of spur dikes at the bend with different values of discharge. The three dimensional flow fields around a spur dike were investigated. The maximum depth of scour was correlated to the Froude numbers, lengths and the locations of spur dike in the bend. | Majid FAZLI Masoud GHODSIAN Seyed Ali Akbar Salehi NEYSHABOURI | 2008 | International Journal of Sediment Research2008，23，1： | 11 |
| 7 | EXPERIMENTAL AND FIELD STUDY ON MINING-PIT MIGRATION显示文摘Rivers are one of the most essential sources of sand and gravel supply for civil works. However, undesirable effects of irregular in-stream mining have been reported on natural sources, environment and infrastructures close to rivers. Therefore, it is necessary to find the effects of mining on rivers in more details. This research concentrates on mining-pit migration phenomenon and its effects on the channel bed. This paper reports an experimental study on the migration of rectangular mining pits and variation of longitudinal profile in the channel bed composed of rather uniform sediments. Different values of widths and lengths were used for pit while pit depths and flow variables were kept constant. The results show that the migration speed changes with the length/width ratio of the pit. The migration speed in convection period is higher than that in diffusion period. In addition, by increasing the length or width, filling rate of pit increases, where the effect of width is more important than the effect of the length. Also is reported in this paper a field study on the changes of three pits excavated at different locations of a river. Some similarities between the pit migration in the straight reach of the river and that of the experimental work is realized and presented. | S.Ali Akbar Salehi NEYSHABOURI Ali FARHADZADEH Ata AMINI | 2002 | International Journal of Sediment Research2002，17，4： | 9 |

| 10 | EFFECT OF POLYANILINE AS A SURFACE MODIFIER OF TiO_2 NANO-PARTICLES ON THE PROPERTIES OF POLYVINYL CHLORIDE/TiO_2 NANOCOMPOSITES显示文摘Surface of TiO2 nanoparticles was modified with the in situ chemical oxidative polymerization of aniline. Polyaniline modified TiO2 nanoparticles (PANI-TiO2 ) were characterized with the FT-IR, XRD, SEM and TEM techniques. Results confirmed that PANI was grafted successfully on the surface of TiO2 nanoparticles, therefore agglomeration of nanoparticles decreased dramatically. Polyvinyl chloride nanocomposites filled with 1 wt% 5 wt% of PANI-TiO2 and TiO2 nanoparticles were prepared via the solution blending method. PVC nanocomposites were analyzed with FT-IR, XRD, SEM, TG/DTA, DSC and tensile test techniques. Effect of PANI as surface modifier of nanoparticles was discussed according to the final properties of PVC nanocomposites. Results demonstrated that deposition of PANI on the surface of TiO2 nanoparticles improved the interfacial adhesion between the constituents of nanocomposites, which resulted in better dispersion of nanoparticles in the PVC matrix. Also PVC/PANI-TiO2 nanocomposites showed higher thermal resistance, tensile strength and Young's modulus compared to those of unfilled PVC and PVC/TiO2 nanocomposites. | Ali Olad Sepideh Behboudi Ali Akbar Entezami | 2013 | Chinese Journal of Polymer Science2013，31，3： | 6 |
| 11 | Biodegradable starch/poly(vinyl alcohol) film reinforced with titanium dioxide nanoparticles显示文摘Biodegradable starch/poly(vinyl alcohol)/nano-titanium dioxide(ST/PVA/nano-TiO2)nanocomposite films were prepared via a solution casting method.Their biodegradability,mechanical properties,and thermal properties were also studied in this paper.A general full factorial experimental approach was used to determine efective parameters on the mechanical properties of the prepared films.ST/PVA/TiO2nanocomposites were characterized by scanning electron microscopy(SEM)and X-ray difraction(XRD).The results of mechanical analysis show that ST/PVA films with higher contents of PVA have much better mechanical properties.In thermal analysis,it is found that the addition of TiO2nanoparticles improves the thermal stability of the films.SEM micrographs,taken from the fracture surface of samples,illustrate that the addition of PVA makes the film softer and more flexible.The results of soil burial biodegradation indicate that the biodegradability of ST/PVA/TiO2films strongly depends on the starch proportion in the film matrix.The degradation rate is increased by the addition of starch in the films. | Zahra Hejri Ali Akbar Seifkordi Ali Ahmadpour Seyed Mojtaba Zebarjad Abdolmajid Maskooki | 2013 | International Journal of Minerals,Metallurgy and Materials2013，20，10： | 5 |

| 14 | Effects of preparation and operation conditions on precipitated iron nickel catalysts for Fischer-Tropsch synthesis显示文摘Iron nickel oxide catalysts were prepared using co-precipitation procedure and studied for the conversion of synthesis gas to light olefins.In particular,the effects of a range of preparation variables such as Fe/Ni molar ratios of the precipitation solution,precipitate aging times,calcination conditions,different supports and loading of optimum support on the structure of catalysts and their catalytic performance for the tested reaction were investigated.It was found that the catalyst containing 40%Fe/60%Ni/40wt%Al 2O3 ,which was aged for 180 min and calcined at 600 ℃ for 6 h was the optimum modified catalyst.The catalytic performance of optimal catalyst has been studied in different operation conditions such as reaction temperatures,H2 /CO molar feed ratios and reaction total pressure.Characterization of both precursors and calcined catalysts was carried out by powder X-ray diffraction(XRD),scanning electron microscopy(SEM),Brunauer-Emmett-Teller(BET) surface area measurements,thermal analysis methods such as thermal gravimetric analysis(TGA) and differential scanning calorimetry(DSC). | Mostafa Feyzi Ali Akbar Mirzaei Hamid Reza Bozorgzadeh | 2010 | Journal of Natural Gas Chemistry2010，19，3： | 4 |
| 15 | Effect of fin attachment on thermal stress reduction of exhaust manifold of an off road diesel engine显示文摘The effect of fin attachment on the thermal stress reduction of exhaust manifold of an off road diesel engine(Komatsu HD325-6) was investigated.For doing this,coupled thermo-fluid-solid analysis of exhaust manifold of the off road diesel engine was carried out.The thermal analysis,including thermal flow,thermal stress,and the thermal deformation of the manifold was investigated.The flow inside the manifold was simulated and then its properties including velocity,pressure,and temperature were obtained.The flow properties were transferred to the solid model and then the thermal stresses and the thermal deformations of the manifold under different operating conditions were calculated.Finally,based on the predicted thermal stresses and thermal deformations of the manifold body shell,two fin types as well as body shell thickness increase were applied in the critical induced thermal stress area of the manifold to reduce the thermal stress and thermal deformation.The results of the above modifications show that the combined modifications,i.e.the thickness increase and the fin attachment,decrease the thermal stresses by up to 28% and the contribution of the fin attachment in this reduction is much higher compared to the shell thickness increase. | Ali Akbar Partoaa Morteza Abdolzadeh Masoud Rezaeizadeh | 2017 | Journal of Central South University2017，24，3： | 4 |
| 16 | Grout diffusion characteristics during chemical grouting in a deep water-bearing sand layer显示文摘The deep,loose bottom aquifer of the eastern air shaft in the Xinglongzhuang Coal Mine was used to develop an experimental model of shaft grouting through Model deep soil.Lab experiments using chemical grouting were done to study the grout.The grouted soil shapes and osmotic pressure were measured during the experiments.The tested characteristics of the grouted soil show that the diffusion mode of grout in saturated sandy soil is a combination of split compaction and osmosis.More specifically,the shape of the grouted soil is determined by split compaction while the size of the grouted soil shape is determined by osmosis.Sensor test results indicate that the main reason for the non-uniform grout diffusion is the anisotropic osmotic pressure field surrounding the grouting holes. | Ali Akbar Daya | 2012 | International Journal of Mining Science and Technology2012，22，4： | 4 |
| 17 | Interaction analysis between slenderness ratio and resin content on mechanical properties of particleboard显示文摘The interaction between particle size and resin content is one of the most important structural parameters that can influence the accuracy of predictions about wood-composite properties. We developed three kinds of equation (linear, quadratic, and exponential) for each mechanical property of particleboard based on slenderness ratio and resin content at a constant density (0.7g cm -3 ). Results from SHAZAM software (version 9) suggested that the quadratic function was not significant, but the linear and exponential functions were significant. The interaction between particle size and resin content was analyzed by Maple 9 software. The results indicated that an exponential function can better describe the simultaneous effect of slenderness and resin content than a linear equation. Under constant resin content, particles with higher slenderness ratios increased more in modulus of rupture (MOR) and modulus of elasticity (MOE) than did particles with lower slenderness ratios. Edge withdrawal resistance (SWRe) values did not increase with increasing slenderness ratio. | Mohammad Arabi Mehdi Faezipour Mohammad Layeghi Ali Akbar Enayati | 2011 | Journal of Forestry Research2011，22，3： | 4 |

| 20 | Enhancing through-plane thermal conductivity of fluoropolymer composite by developing in situ nano-urethane linkage at graphene–graphene interface显示文摘Attributed to the intense development and complexity in electronic devices,energy dissipation is becoming more essential nowadays.The carbonaceous materials particularly graphene(Gr)-based thermal interface materials(TIMs)are exceptional in heat management.However,because of the anisotropic behavior of Gr in composites,the TIMs having outstanding through-plane thermal conductivity(┴TC)are needed to fulfill the upcoming innovation in numerous devices.In order to achieve this,herein,nano-urethane linkage-based modified Gr and carbon fibers architecture termed as nanourethane linkage(NUL)-Gr/carbon fibers(CFs)is fabricated.Wherein,toluene diisocyanate is utilized to develop a novel but simple NUL to shape a new interface between graphene sheets.Interestingly,the prepared composite of NUL-Gr/CFs with polyvinylidene fluoride matrix shows outstanding performance in heat management.Owing to the unique structure of NUL-Gr/CFs,an unprecedented value of┴TC(~7.96 W·m^–1·K^–1)is achieved at a low filler fraction of 13.8 wt.%which translates into an improvement of^3,980%of pristine polymer.The achieved outcomes elucidate the significance of the covalent interaction between graphene sheets as well as strong bonding among graphene and matrix in the composites and manifest the potential of proposed NUL-Gr/CFs architecture for practical applications. | Muhammad Maqbool Haichang Guo Akbar Bashir Ali Usman Adeel YAbid Guansong He Yanjuan Ren Zeeshan Ali Shulin Bai | 2020 | Nano Research2020，13，10： | 3 |
