This is the Book of knowledge wisdom. The language of the Holy Quran is Arabic although several words have been derived from other languages e.g., Roman, Hebrew and Persian etc. In this article such words & terminologies have been identified from their origins. More over these words have been analyzed with respect to their meanings. It is worth considering that these words lose their originality whatsoever after getting the Arabic structure.

The Optimal Homotopy Asymptotic Method (OHAM) is applied to derive a solution of the reduced fourth-order nonlinear boundary value problem. For comparison, the same problem is also solved by ...

Nineteen children showed acute hemolytic anemia, a leukemoid reaction, thrombocytopenia and oliguria; nine other had, in addition, a serum urea nitrogen level of over 100 mg per diciliter. Eight of the nine had pseudomembranous colitis, and six of the nine died. The frequency of bacteremia was similar in all grades of shigellosis. Circulating immune complexes were found in 10 of 20 patients with uncomplicated shigellosis and in four of six with severe hemolytic-uremic syndrome. Limulus assay for endotoxemia was positive in nine of 18 patients with hemolysis (50 per cent) and three of 61 with uncomplicated shigellosis (5 per cent) (P less than 0.001). These data support the hypothesis that severe colitis in shigellosis is associated with circulating endotoxin from the colon producing coagulopathy, renal microangiopathy and hemolytic anemia.

Water, sediment, and bivalves collected from the Buriganga River at Dhaka, Bangladesh, were examined. As demonstrated in many previous studies, fecal coliform counts were consistently higher for the bivalve tissue than those for water and sediment samples; in the bivalve Lamellidens marginalis, they were ~ 10.0-to 87.0-fold higher than those in water, and 2.0-to 11.0-fold higher than those in sediment.

The paper contributes to the domain of design research knowledge as it critically discusses as well as exemplifies the use of DSR in an interpretive research perspective that aims at solving some socio-economic problems, which is significantly lacking in contemporary research. The major argument here is that DSR can be fruitfully used in ICT4D research as long as the goal of ICT4D research is to innovate or design something new. Furthermore, due to the stage-gate model nature of DSR, its comprehensive use in ICT4D needs an integrated research approach with well-coordinated activities throughout the development process.

A mathematical governing model has developed for the momentum, temperature and concentration boundary layer. Similarity transformations using to modify the boundary layer equations. Whereas this prominent transformations are used to transform the principal nonlinear boundary layer equations for momentum, thermal energy and concentration to a system of nonlinear ordinary coupled differential equations with fitting boundary conditions. The coupled differential equations are numerically simulated using the famous Nactsheim-Swigert shooting technique together with Runge-Kutta six order iteration schemes. Pertinent results with respect to embedded parameters are displayed graphically for the velocity, temperature and concentration profiles and were discussed quantitatively. Skin-friction, Heat transfer rate (Nusselt number) and mass transfer rate (Sherwood number) are illustrated for the various important parameters entering into the problem separately are discussed with the help of graphs. Finally for the accuracy of the present results a comparison with previously published research work are accomplished and proven an excellent agreement.

The analysis is accompanied by testing differential transform method both on linear and nonlinear problems from the literature [Wazwaz AM. Approximate solutions to boundary value problems of higher-order by the modified decomposition method. Comput Math Appl 2000:40;679-91; Siddiqi SS, Ghazala Akram.

J Comput Appl Math 1997;78:371-90]. Numerical experiments and comparison with existing methods are performed to demonstrate reliability and efficiency of the proposed method.
