قیام امن اور حیات نبوی: ایک مثالی دور

Peace initiatives during the regime of the Prophet attain to how understand to studied be to needs (صلى الله عليه وسلم) Muhammad and maintain peace in a diverse society. The measures for peace, taken by the Prophet (ﷺ) can be divided into two types: The Internal Steps and The External Steps. One of the fundamental objectives of his prophetic annunciation was ‘purification and refinement’, which was the core of his internal measures for peace. These measures produced moral values such as love and harmony, reconciliation and sacrifice among them. These personality traits were then translated into the establishment of equitable justice system and reciprocally, a just system leads to shape behaviors contributing to peace and harmony. For steps external the on focused also (صلى الله عليه وسلم) Prophet The peace. These external measures include the treaty of al-Madīnah, the agreement with the Christian delegation of Najrān, the treat of Ḥudaybiyah and the announcement of the amnesty at the conquest of Mekkah. Thus, the study of the Prophet’s (ﷺ) life unfolds that if we want global peace, we have to follow the principles, practiced. (صلى الله عليه وسلم) Prophet the by down laid and

On Boundary Layer Flow and Heat Transfer to Burgers Fluid

The aim of this thesis is to furnish some theoretical results in the field of non-Newtonian fluid mechanics. The research presented in the thesis is concerned with the mathematical modeling and development of analytical solutions for non-Newtonian fluids. Particularly, this thesis focuses on the boundary layer flows of Burgers and generalized Burgers fluids induced by the stretching surface. Thus the theme of thesis is twofold. First, the development of the boundary layer equations for steady two- and three-dimensional flows of Burgers and generalized Burgers fluids. Second, to give a better understanding of their behaviors, the development of the analytical results for them in diverse circumstances. The problems considered here involve, the forced convective heat transfer over linear stretching surfaces by assuming different situations like nanofluid, Cattaneo-Christov heat and mass flux models, homogeneous-heterogeneous and melting processes. The modeled PDEs are transformed into ODEs by utilizing suitable transformations which are then solved by employing HAM. In the limiting cases, our solutions are in excellent agreement with previously reported results in the literature. To assess and demonstrate the physical aspects of our results, some of the velocity, 17 temperature and concentration profiles are presented graphically for emerging parameters and discussed in detail. Moreover, the local Nusselt and Sherwood numbers are presented in tabular form for a set of values of the non-dimensional parameters. A profound observation is that the velocity and associated momentum boundary layer thickness diminish with augmented values of the materials parameter ?2 of Burgers fluid; however, quite the opposite is true in case of the material parameter ?4 of generalized Burgers fluids. In addition, it is noticed that temperature and concentration profiles enhance as the material parameter ?2 is incremented. It is further observed that the temperature and concentration distribution possess a reverse behavior for the material parameter ?4 when compared with ?2. Indeed this thesis leads us to suggest that the results owing from the Burgers and generalized Burgers models do provide a much improved understanding of their rheological characteristics.
