In this paper, the steady boundary layer flow and heat transfer of a micropolar fluid on an isothermal continuously moving plane surface is studied analytically. It is assumed that the microinertia density is variable and the viscous dissipation effect is taken into account. The system of nonlinear ordinary differential equations is solved analytically using the homotopy analysis method (HAM) and the results are obtained for various flow and heat transfer characteristics. By using HAM, accurate analytic series solutions are obtained in the whole spatial region. Also, a new suggestion for choosing the proper value of the auxiliary parameter ℏ in the convergence region is proposed. It is observed that the present solutions have higher accuracy when the residual error is obtained. The present results show that this algorithm is effective and can be similarly applied to other nonlinear equations. © 2010 John Wiley & Sons, Ltd.

The properties of lightweight concrete containing pumice treated with sodium hypochlorite (NaOCl) were experimentally investigated in this study. The study used treated pumice as 100% replacement of fine and coarse aggregates in concrete mixtures. Untreated pumice aggregates were used to prepare reference mixtures. In addition, the study investigated the effect of sodium hypochlorite on pumice properties. The concrete compressive strength at ages of 7 and 28 days was tested. The results showed that the compressive strength of concrete that contained treated pumice increased by 200% as compared to concrete containing untreated pumice. The pumice aggregate treated with NaOCl increased the pumice strength and improved its physical characteristics as the mean of specific gravity and abrasion resistance. © 2016 JUST.

This research studied the influence of internal heat generation on flow and heat transfer in a thin liquid film on an unsteady stretching sheet. The velocity and temperature fields were solved using the Homotopy Analysis Method (HAM), taking a general surface temperature into consideration. The analytical series solution are presented and the numerical results obtained are tabulated. The effects of unsteadiness parameter, Prandtl number and temperature-dependent parameter in this study are discussed and presented graphically via the velocity and temperature profiles. © Springer Science+Business Media B.V. 2010.

This study presents a discussion for fusing polymers as cells of the diesel particulate filter i.e., as a porous media. The transmission losses of sound waves and noise reduction will be calculated for different values of frequency and a comparison between ceramics and polymer filters is demonstrated. It is found that polymers cells improving transmission losses and noise reduction factor of the DPF. © Maxwell Scientific Organization, 2012.

This study provides an overview for the utilization of different catalytic material in the synthesis of organic compounds for important reactions such as heck reaction, aldol reaction, Diels- Alder and other reactions. Comparisons between multiple catalysts for the same reaction and justifications for developing new catalyzed materials are discussed. The following topics are introduced in this work; (1) solid base catalysts, (2) clay catalysts, (3) palladium catalysts, and (4) catalysts to produce organic compound from CO2. The features of these catalysts a long with the conjugated reactions and their selectivity are explained in details, also, some alternatives for toxic or polluting catalysts used in industry are suggested. © Maxwell Scientific Organization, 2011.
