قرآنی اور غیر قرآنی زندگی کا تقابل اور جائزہ

Allah has blessed the human beings with countless blessings, among these; the two most important are life and Quran. To be thankful for these blessings is compulsory, however, it is to be mentioned with regret that we are unaware of this obligation. Life that is not passed in accordance with the defined pattern and stipulations of Quran is a non Quranic pattern of life. Today Muslims have lost dignity by putting aside the Quranic teachings. What is Quranic pattern of life? To know it one has to dive into the sea of Quran and then need to find pearls and shells by pondering and considering on we can unveil the secrets of the universe. Non Quranic pattern of life is not the guarantee of success, rather it is a disgrace in both the worlds. If life is to set on Quranic pattern then one understand Quran well. To deny useless deeds, false beliefs and civilization of human beings are the objectives of Quranic study. ALLAH also wants the same from Believers. Quran is the mentor of all worldly knowledge. All other disciplines are derived from it and all are dependent on the Quran. Therefore it is necessary to have a purposed life and to come out of purposeless life. Once the pattern is according to Quran, all the disappointments and worries of life would end gradually. Life in the light of ALLAH’s orders is a guaranteed peaceful, blessed and eternal successful. What actions come under Quranic pattern of life and which life goes out of its vicinity, this would be discussed in detail in this article.

Solutions of Couple Stress and Non-Newtonian Fluid Flows

The equations governing the flow of couple stress and modified second grade non-Newtonian fluid flows for systems of non-linear ordinary differential equations are formed and thus these systems have no general solutions. The general solutions become more rare if we study these flows together with heat transfer analysis and even more harder if we introduce the variable viscosity instead of constant viscosity. In the first part of the thesis we study the steady incompressible couple stress channel fluid flows together with the energy equations taking variable viscosity into account. The Reynolds and Vogel’s viscosity models have been used for the temperature dependent viscosity. Depending on the relative motion of the plates, four different problems are considered, viz plane Couette flow, plug flow, plane Poiseuille flow and Couette- Poiseuille flow. Approximate analytical and numerical approaches have been used to solve the nonlinear developed equations arising during the mathematical modeling of these problems. Solutions for the velocity profiles, temperature distributions, volumetric flow rates, average velocities Nusselt number and shear stresses are obtained. The influence of different emerging parameters on the flow pattern has been discussed and presented with the help of graphs. A study of thin film flows for the Generalized (modified) second grade fluid together with the energy equation is carried out in the next part of the analytical investigation. Two different problems have been investigated, (i) when a wide belt is moving vertically upward through a container with a constant speed V0 and (ii) when fluid is falling on the stationary infinite vertical belt under the influence of gravity. For the above stated problems the governing equations are converted into ordinary differential equations and then solved exactly for the velocity profile and temperature distribution. Expressions for the volume flux, average velocity and shear stress are obtained in both these problems. Effects of different parameters on velocity and temperature are presented graphically. Furthermore approximate solutions have been developed for the Generalized second grade fluid in cylindrical coordinates.
