| 7 | Finite element solution of nonlinear convective flow of Oldroyd-B fluid with Cattaneo-Christov heat flux model over nonlinear stretching sheet with heat generation or absorption显示文摘In this study,a two-dimensional boundary layer flow of steady incompressible nonlinear convective flow of Oldroyd-B fluid over a nonlinearly stretching sheet with Cattaneo-Christov heat flux model and heat generation or absorption is examined.The governing equations of the boundary layer flow which are highly nonlinear partial differential equations are converted to the ordinary differential equations using similarity transformations and then the Galerkin finite element method(GFEM)is used to solve the proposed problem.The effect of local Deborah numbers 0,and ft.local buoyancy parameter z,Prandtl number Pr,Deborah number y,and heat generation/absorption parameter<5 on the temperature and the velocity as well as heat transfer rate and shear stress are discussed both in graphical and tabular forms.The result shows the enlargement in the local buoyancy parameter A will improve the velocity field and the heat transfer rate of the boundary layer flow.Moreover,our present work evinced both local skin friction coefficient and heat transfer rate step up if we add the values of non-linear stretching sheet parameter and local heat generation/absorption parameter has quite the opposite effect.The numerically computed values of local skin friction coefficient and local Nusselt number are validated with available literature and evinced excellent agreement. | Wubshet Ibrahim Gosa Gadisa | 2020 | Propulsion and Power Research2020，9，3： | 1 |

| 14 | Salting-out Assisted Liquid-Liquid Extraction for Analysis of Caffeine and Nicotinic Acid in Coffee by HPLC-UV/Vis Detector显示文摘A salting-out assisted liquid-liquid extraction method followed by high performance liquid chromatography with ultravio-let-visible detector(SALLE-HPLC-UV/Vis)has been proposed for determination of caffeine and nicotinic acid in raw and roasted coffee samples.Various parameters affecting chromatographic separations including mobile phase composition,injec-tion volume,flow rate and column temperature were studied.Experimental parameters affecting the extraction efficiency of SALLE method such as type and volume of the organic solvent,type and amount of salt,pH of the sample,and concentration of the ion-pairing reagent were also studied and thereby optimum conditions were established.The calibration curves which were constructed at five different concentration levels using the optimum conditions exhibited good linearity,with the coef-ficient of determination(R2)0.999 and 0.995 for caffeine and nicotinic acid,respectively.The limits of detection(LOD)and quantification(LOQ)which were determined at 3 and 10 times signal-to-noise ratio were 0.05 and 0.13 mg/L for nicotinic acid and 0.20 and 0.63 mg/L for caffeine,respectively.Intra-and inter-day precision studies were demonstrated satisfactory precision with RSD values below 10.Relative recoveries were also studied,and their results were ranging from 82-122%for both raw and roasted coffee samples.The findings demonstrated that the proposed method could be used as an effective and best alternative for the determination of caffeine and nicotinic acid in raw and roasted coffee samples. | Gadisa Chirfa Yared Merdassa Abera Gure | 2020 | Journal of Analysis and Testing2020，4，4： | 1 |
