ریزۂ ریگ
میں ریگ ِ رواں کا اک مضطرب ذرا
دشت کی پہنائی میں بھٹکتا ہوا
آندھیوں کی غلامی میں اڑتا ہو
جس کا وجود دوسرے ریگ ریزوںکے سوا کچھ نہیں
جس کی اندھی قسمت میںدشت کی اذیتوں کے سوا کچھ نہیں
اپنے وجود سے روز جدا ہوتا ہوا
اپنے خشک آنسو نگلتا ہوا
کبھی ریت کے بھاری ٹیلوں میں دب گیا
کبھی سطحِ ریگ پر حدت سے جل گیا
Syariah banking as an important component of banking law in Indonesia is currently experiencing rapid growth. The existence of Shariah banking is expected to help solve various problems in Indonesia, especially poverty. In the midst of its development, Shariah banking has not been able to handle the market share where the majority of the market share comes from people from the middle class. In addition, the education and socialization of Shariah banking is insufficient, so there is a diversity of public perceptions regarding Shariah banking. Pros and cons occur in society regarding the establishment of Sharia banks, where the benefits of Sharia banking are enormous, both in the economic world and in the future. This research uses literature review. Review using a qualitative approach. Primary data sources in this research were obtained from observations or research observations on problems that occur with Sharia banking management. Meanwhile, secondary data was obtained from good literature and books, journals and other sources related to current materials.
In this dissertation, a new semi analytical technique has been developed to determine the transformed solutions of non-Newtonian fluids subject to different circumstances involving fractional derivatives. The unsteady motion of viscoelastic fluids, such as Walters’-B fluid, Maxwell fluid, Oldroyd-B fluid and Burgers’ fluid involving fractional derivatives has been discussed with the developed technique. This semi analytical technique has less computational effort and time cost compared to other existing schemes in the literature. In Chapter 2, Caputo-Fabrizio fractional derivative have been developed to study the heat and mass transfer of free convective motion of Walters’-B fluid through an infinite porous vertical plate in the presence of magnetic field. In Chapter 3, the approximate solutions for velocity field and shear stress of a Maxwell fluid using Caputo fractional derivatives have been developed. In Chapter 4 and 5, Caputo fractional derivative has been developed to study velocity field and shear stress in an infinite long circular cylinder subject to an Oldroyd-B fluid and Burgers’ fluid, respectively.
