احسان اﷲ ثاقب(۱۹۴۲ء۔۲۰۱۴ء) پسرور میں پیدا ہوئے۔ آپ معروف رومانوی شاعری فاخر ہریانوی کے بیٹے ہیں- اعلی تعلیم حاصل کرنے کے بعد محکمہ تعلیم میں ملازمت اختیار کی۔ (۹۸۲)آپ کا ایک شعری مجموعہ ’’شہرِ غزل‘‘ کے نام سے معراج پر نٹرز لاہورسے ۲۰۰۶ء میں شائع ہوا۔ اس کے علاوہ کچھ شعری مسودات ہیں جو شائع نہیں ہو سکے۔ احسان اﷲ ثاقب غزل گو شاعر ہیں۔ ان کا اردو ادب میں بڑا کارنامہ یہ ہے کہ انھوں نے اپنے شعری مجموعے ’’شہرِ غزل‘‘ میں بیس بحور کے چھیاسی اوزان میں بڑی خوبصورتی سے طبع آزمائی کی ہے۔ آج ارد وشاعری میں کوئی قدآور شاعر بھی اتنی تعداد میں بحور اور اوزان میں شعر نہیں کہہ سکا ہے۔ انھوں نے ایک نئی بحر کا بھی اضافہ کیا ہے۔ جسے انھوں نے ’’بحرِ مترنم‘‘ کانام دیا ہے۔ یہ بحر تمام عروضی تقاضوں کو پورا کرتی ہے۔

Islamic literary legacy is diverse and multidimensional in Sub-continent despite its being prone to religious b and the issue of migration integral part of Islamic literary legacy is the Quranic translations & interpretations. The main aspect of these translations & interpretations are the endeavors put forward by Muslim as well as non-Muslim scholars. Keeping in view the endeavors translations & interpretations of Quran, the non-Muslims minorities of sub-continent can be divided into two groups. The first group of part is based on the followers of Judaism, Parsee, Buddhist, Sikhism, Jainism and idols of Kalash whose translations and interpretations is not well known. Whereas, the second group endure Christians, Hindus and Qadyanis. Christians and Hidus consider Quran as non-revealed. Since the style of their interpretations is based on criticism and rejection in aggressive manner. Whereas the interpretations by Qadyanis are focused on religious polarized beliefs and ideologies taking into considerations Quran as revealed. That’s why Qadyanis interpretations are not accepted in Muslim community. The criticism by non-Muslims writers has resulted in rational approach for study of Quran instead of tendency based on esteem among Muslim. This paper represents aforementioned non-Muslims services regarding Quranic Interpretations and Translations which are distinguished in Muslims Interpreters.
The primary purpose of this dissertation is to study the nonlinear screening effect of electrostatic field and the nonlinear structure of ion-acoustic solitary waves in relativistic degenerate electron-positron-ion plasmas. Nonlinear screening process in ultrarelativistic degenerate electron-positron gas is investigated by deriving a generalized nonlinear Poisson equation for the electrostatic potential. In the simple one-dimensional case, the nonlinear Poisson equation leads to Debye-like (Coulomb-like) solutions at distances larger (less) than the characteristic length. When the electrostatic energy is larger than thermal energy this nonlinear Poisson equation converts into the relativistic Thomas-Fermi equation whose asymptotic solution in 3D shows that the potential field goes to zero at infinity much more slowly than the Debye potential. The possibility of the formation of a bound state in electron-positron plasma is also indicated. Further, it is investigated that the strong spatial fluctuations of the potential field may reduce the screening length and that the root mean square of this spatial fluctuating potential goes to zero for large distance rather slowly as compared with the case of the Debye potential. The arbitrary and small amplitude ion acoustic solitary waves are studied separately in all three regimes (relativistic, non-relativistic and ultra-relativistic). The former is studied by using Sagdeev type-pseudo potential approach in plasmas consisting of collisionless, unmagnetized and degenerate dense electron-positron, and the non- relativistic cold classical ions. The electrons and positrons are assumed to follow the corresponding Fermi Dirac distribution function while the ions are described by the hydrodynamic equations. It is significant to note that the ion-acoustic speed in the degenerate pair-ion plasma does not only depend upon the electron Fermi temperature and ion mass, it also depends upon the concentration of the positrons and the ions in the plasma. Along with approximate solution, the exact amplitude solitary structure is also investigated numerically. It is seen that only compressive and supersonic solitary waves can propagate through such plasmas. The presence of the positions in the plasma drastically reduces the amplitude of the ion-acoustic solitary waves while the plasma thermal temperature increases it slightly.
