| 3 | 具有二元化学反应和活化能的压缩流体的磁流体动力学(英文)显示文摘研究了在外加磁场作用下,黏性流体在压缩通道中的运动规律。热量和质量传输过程涉及温度依赖的二元化学反应和修正的Arrhenius活化能函数理论,但是该理论尚未揭示挤压流动机理。在无滑移壁边界条件下,流场、热场和质量场通过无量纲、高度非线性的常微分方程来控制。采用一种收敛性稳定的解析方法求解边值问题。对各种新出现参数的流速场、温度场和流体浓度分布的图进行了详细的研究,获得了表面摩擦、Nusselt和Sherwood数并以图表形式表现。结果表明,流体温度随着占主导地位的无量纲反应速率σ和活化能E的增加而升高。然而,σ和E的增加随着流体浓度的增加而下降。当前研究应用于许多工程和工业过程包括聚合物工业、压缩和注塑成型、润滑系统、纸张的生产、塑料薄膜的成型。在化学工程和地热领域,可以利用磁场来控制核冷却反应、核或化学系统、双分子反应、生化过程和导电聚合物流动。在这些应用的推动下,此研究已得到发展。 | S.AHMAD M.FAROOQ N.A.MIR Aisha ANJUM M.JAVED | 2019 | Journal of Central South University2019,26,5: | 2 |
| 4 | Nanoscale mass sensing based on vibration of single-layered graphene sheet in thermal environments显示文摘Based on vibration analysis,single-layered graphene sheet(SLGS)with multiple attached nanoparticles is developed as nanoscale mass sensor in thermal environments.Graphene sensors are assumed to be in simplysupported configuration.Based on the nonlocal plate theory which incorporates size efects into the classical theory,closed-form expressions for the frequencies and relative frequency shifts of SLGS-based mass sensor are derived using the Galerkin method.The suggested model is justified by a good agreement between the results given by the present model and available data in literature.The efects of temperature diference,nonlocal parameter,the location of the nanoparticle and the number of nanoparticles on the relative frequency shift of the mass sensor are also elucidated.The obtained results show that the sensitivity of the SLGSbased mass sensor increases with increasing temperature difference. | S.Ahmad Fazelzadeh Esmaeal Ghavanloo | 2014 | Acta Mechanica Sinica2014,30,1: | 2 |
| 5 | Effects of Supplementing Various Linoleic to α-linolenic Acid Ratios and Vitamin A on Production Performance and Egg Characteristics of Laying Hens during Summer Months显示文摘In the present feeding trial,responses of laying hens that were kept at high ambient temperature and Fed with various dietary ratios of linoleic acid(LNA)toα-linolenic acid(ALA)and vitamin A levels on production performance and egg quality traits were evaluated.A total of 360 Leghorn laying hens at 40th week of age(average initial body weight;1.79±0.23 kg)were fed with various combinations of canola oil and linseed oil containing diets to achieve LNA to ALA dietary ratios of 20:1,10:1,4:1,2:1,1:1 and 1:2,each supplemented with 3000 or 10000 IU of vitamin A/kg of diet.The experiment was designed as a 6×2 factorial Completely Randomized Design that continued for 12 weeks.Feed intake,body weight gain,egg production and egg quality traits were recorded during the trial.Decreasing dietary LNA to ALA ratio or increasing poly unsaturated fatty acids(PUFA)in the diet decreased(P<0.05)body weight gain and yolk percentage in laying hens.Feed intake,hen-day and hen-housed egg production,feed conversion ratio(FCR)per dozen of eggs and shell quality remained unaffected(P>0.05)by dietary treatments.Feed conversion ratio per kg eggs,egg weight and egg-shell thickness showed a curvilinear(P<0.05)response to decreasing dietary LNA to ALA ratio.Although the dietary ratio of LNA to ALA of 4:1 or less could produce eggs by the hens with desirable quantities of n-6 and n-3 PUFA–that are characteristics of functional diets–the performance of laying hens in terms of body weight gain and egg-yolk percentage was slightly compromised.Therefore,a 4:1 or 2:1 LNA to ALA combination can make a borderline between the production traits and the feed economics. | S.Ahmad M.Yousaf Z.Kamran M.U.Sohail M.N.Tahir K.C.Koutoulis A.Manzoor 无 | 2019 | Journal of Zoological Research2019,1,1: | 1 |

| 7 | Pulsed ion beam-assisted carburizing of titanium in methane discharge显示文摘The carburizing of titanium (Ti) is accomplished by utilizing energetic ion pulses of a 1.5 kJ Mather type dense plasma focus (DPF) device operated in methane discharge. X-ray diffraction (XRD) analysis confirms the deposition of polycrystalline titanium carbide (TiC). The samples carburized at lower axial and angular positions show an improved texture for a typical (200)TiC plane. The Williamson-Hall method is employed to estimate average crystallite size and microstrains in the carburized Ti surface. Crystallite size is found to vary from ~ 50 to 100 nm, depending on the deposition parameters. Microstrains vary with the sample position and hence ion flux, and are converted from tensile to compressive by increasing the flux. The carburizing of Ti is confirmed by two major doublets extending from 300 to 390 cm-1 and from 560 to 620 cm-1 corresponding to acoustic and optical active modes in Raman spectra, respectively. Analyses by scanning electron microscopy/energy dispersive x-ray spectroscopy (SEM/EDS) have provided qualitative and quantitative profiles of the carburized surface. The Vickers microhardness of Ti is significantly improved after carburizing. | M.Shafiq M.Hassan K.Shahzad A.Qayyum S.Ahmad R.S.Rawat M.Zakaullah | 2010 | Chinese Physics B2010,19,1: | 1 |
| 8 | Damped Kadomtsev–Petviashvili Equation for Weakly Dissipative Solitons in Dense Relativistic Degenerate Plasmas显示文摘We have investigated the properties of three-dimensional electrostatic ion solitary structures in highly dense collisional plasma composed of ultra-relativistically degenerate electrons and non-relativistic degenerate ions. In the limit of low ion-neutral collision rate, we have derived a damped Kadomtsev–Petviashvili(KP) equation using perturbation analysis. Supplemented by vanishing boundary conditions, the time varying solution of damped KP equation leads to a weakly dissipative compressive soliton. The real frequency behavior and linear damping of solitary pulse due to ion-neutral collisions is discussed. In the presence of weak transverse perturbations, soliton evolution with damping parameter and plasma density is delineated pointing out the extent of propagation using typical parameters of dense plasma in the interior of white dwarfs. | S.Ahmad Ata-ur-Rahman S.A.Khan F.Hadi | 2017 | Communications in Theoretical Physics2017,67,12: | 0 |

| 10 | Investigation of generalized Fick's and Fourier's laws in the second-grade fluid flow显示文摘The second-grade fluid flow due to a rotating porous stretchable disk is modeled and analyzed. A porous medium is characterized by the Darcy relation. The heat and mass transport are characterized through Cattaneo-Christov double diffusions.The thermal and solutal stratifications at the surface are also accounted. The relevant nonlinear ordinary differential systems after using appropriate transformations are solved for the solutions with the homotopy analysis method(HAM). The effects of various involved variables on the temperature, velocity, concentration, skin friction, mass transfer rate, and heat transfer rate are discussed through graphs. From the obtained results,decreasing tendencies for the radial, axial, and tangential velocities are observed. Temperature is a decreasing function of the Reynolds number, thermal relaxation parameter,and Prandtl number. Moreover, the mass diffusivity decreases with the Schmidt number. | T.HAYAT S.AHMAD M.I.KHAN A.ALSAEDI | 2018 | Applied Mathematics and Mechanics(English Edition)2018,39,11: | 0 |
| 11 | Investigations of Viscous Dissipation in Stagnation Point Flow Past a Stretchable Riga Wall: Modern Analysis of Heat Transport显示文摘This article scrutinizes the features of viscous dissipation in the stagnation point ?ow past through a linearly stretched Riga wall by implementing Cattaneo-Christov heat ?ux model. Viscous dissipation is carried out in Cattaneo-Christov diffusion analysis for the ?rst time in this letter. As a result of Cattaneo-Christov model, some extra terms of viscous dissipation are appeared in the energy equation. These extra terms of viscous dissipation are missing in the literature. On the utilization of suitable transformations, the equations governing the problem are reduced under the boundary layer approximation into the non-linear and dimensionless ordinary differential equations. Convergent approach is utilized to solve the dimensionless governing equations. The solution thus acquired is used to highlight the effects of emerging parameters on velocity distribution and ?uid's temperature through the graphs. Features of the drag force(or skin friction co-e?cient) are graphically interpreted. It is noticed that the presence of modi?ed Hartman number helps to reduce the ?uid's temperature but enhances the velocity pro?le. Further an enlargement in the value of thermal time relaxation parameter helps to decrease the temperature distribution. | Aisha Anjum N.A.Mir M.Farooq M.Javed S.Ahmad | 2019 | Communications in Theoretical Physics2019,71,4: | 0 |
| 12 | Chaetomium-like fungi causing opportunistic infections in humans:a possible role for extremotolerance显示文摘Members of the family Chaetomiaceae are ubiquitous ascosporulating fungi commonly,which reside in soil enriched with manure or cellulosic materials.Their role as human pathogens is largely ignored.However,the ability of some species to grow at high temperature enables them to play an important role as opportunistic pathogens.The family contains several genera and species that have never been reported to cause human infection.Hereby,three new species are described;two belong to the genus Subramaniula and one represents a Chaetomium species.Subramaniula asteroides was isolated from various sources including eye and skin infections as well as from the natural environment,and S.obscura was isolated from a toe infection.Chaetomium anamorphosum was isolated from a kidney transplant patient suffering from fungal peritonitis.All species described were previously misidentified as Papulaspora spp.due to the formation of cellular clumps or bulbil-like structures,which are characteristic of Papulaspora.The isolates failed to form sexual fruit bodies and ascospores remained absent,which is an unusual feature for the generally ascosporulating genera Chaetomium and Subramaniula;minute conidia from phialides were sometimes observed. | Sarah A.Ahmed Ziauddin Khan Xue-wei Wang Tarek A.A.Moussa Hassan S.Al-Zahrani Omar A.A.lmaghrabi Deanna A.Sutton S.Ahmad Johannes Z.Groenewald A.Alastruey-Izquierdo Anne van Diepeningen S.B.J.Menken M.J.Najafzadeh Pedro W.Crous Oliver Cornely Axel Hamprecht Maria J.G.T.Vehreschild A.J.Kindo G.Sybren de Hoog | 2016 | Fungal Diversity2016,,1: | 0 |
