The model of combined forced and free convection in a vertical parallel-plate channel with prescribed wall heat fluxes was presented by considering a fully developed flow and by taking into account the effect of viscous dissipation. In this paper, homotopy solution for the model is obtained. Convergent region of the homotopy analysis method solution is presented. Residual error for the HAM solution is presented graphically. © 2010 John Wiley & Sons, Ltd.

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.

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.

In this paper, the numerical-analytical solution for the hyperchaotic Chen system is obtained via the multistage homotopy analysis method (MSHAM). An analytical form of the solution within each time interval is given, which is not possible using standard numerical methods. The numerical results obtained by the MSHAM and the classical fourth-order Runge-Kutta (RK4) method are in complete agreement. Moreover, the residual error for the MSHAM solution is given for each time interval. © 2010 The Royal Swedish Academy of Sciences.

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.

To evaluate the effect of vitamin C and zinc on performance and immune-competence during heat stress. Four hundred and eighty, 1 day old Arbor Acres broiler males and females were used and raised in either a thermoneutral (control) or heat stressed (40°C) environment where different levels of vitamin C and zinc were supplemented. Humoral immunity was assessed by intravenous injection of Sheep Red Blood Cells (SRBC) followed by evaluation of serum for antibody titers in primary and secondary responses. Heat stressed birds that supplemented with vitamin C and Zinc showed greater (p = 0.5) body weight, higher daily gain, better feed conversion ratio and less mortality than the non-supplemented control group. Total, IgM and IgG antibody titers for primary and secondary responses were significantly increased in birds receiving vitamin C and zinc with variable levels according to the concentration of vitamin C and zinc. These results indicated that the immune response of broilers can be influenced under heat stress conditions by combination of different levels of vitamin C and Zinc in the diet. The recommended levels of vitamin C and Zinc depend on environmental conditions and other factors which still need further manipulation. © 2012 Knowledgia Review, Malaysia.

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.

Frequent itemset mining assists the data miner in searching for strongly associated items (and transactions) in large transaction databases. Since the number of frequent itemsets is usually extremely large and unmanageable for a human user, methods for mining interesting rules have been proposed to define meaningful and summarized representations of them. Furthermore, many measures have been proposed in the literature to determine the interestingness of the rule. In this paper, we introduce a new temporal measure for interesting frequent itemset mining. This measure is based on the idea that interesting frequent itemsets are mainly covered by many recent transactions. This measure reduces the cost of searching for frequent itemsets by minimizing the search interval. Furthermore, this measure can be used to improve the search strategy implemented by the Apriori algorithm. © 2010 IEEE.

Density functional theory (DFT) calculations are performed to investigate the CO oxidation on Ir(100) surface at different CO coverages, 0.125, 0.25, and 0.5 monolayers (ML). The reaction pathway and transition state (TS) are determined using constrained minimization and nudged elastic band (NEB) methods. We found that the CO molecule is significantly more mobile toward O atoms, which causes a weakening of the O-metal bond. The increase of CO coverage leads to a decrease in the activation energy of the reaction and an increase of Oa-CO distance where O coverage is kept at 0.25 ML. © 2011 WILEY-VCH Verlag GmbH & Co.
