اندھیروں میں کھلا کیسا دریچہ

اندھیروں میں کھلا کیسا دریچہ
حرا سے روشنی دیتا دریچہ

نہ جانے کب کہیں سے نعت اُترے
خیالوں کا کھلا رکھا دریچہ

سدا آئے صدا صلِّ علیٰ کی
نبیؐ کے ذکر کا رسیا دریچہ

ہوائے سبز آتی ہے وہاں سے
بنا ہے گنبدِ خضرا دریچہ

ہوئی مدت مدینے حاضری کی
کھلا ہے اب بھی یادوں کا دریچہ

بہ رنگِ اجتہاد، اجماع ِ اُمت
یہی ہے فِکر تازہ کا دریچہ

مجھے سرشار رکھتا ہے یہ گھر میں
مدینے کی طرف رکھا دریچہ

سخن کو معتبر رکھتا ہے ہر دم
یہ رنگِ نعت میں ڈوبا دریچہ

عصر حاضر میں مسلمانوں کی سیاسی ابتری اور اس کا تدارک: سیرتِ طیبہﷺ کی روشنی میں

The noble life Of Rasulullah (ﷺ) provides the best after course and framework for the individual and collective life of Muslims which can lead Muslims to prosper in each part of life. Out of different problems of the Muslim Ummah in the current circumstances is the absence of political insight and exemplary leadership which is one of the most important problems and due to which Muslims are victim of decline on international basis. The political and national problems of Muslims include the absence of exemplary leadership, Muslim Ummah getting victim of mutual differences, deprivation of the majority of Muslim rulers of bravery and boldness, shortage of the wellbeing of the public, excess of corruption and fraud, absence of self-accountability in the public and rulers, not complying with the rules of justice, shortage of qualified and experienced individuals in different departments and institutions along with some other similar problems. Without getting them solved, the dreams of prosperity and success of Muslim Ummah cannot be fulfilled. We can find the solution of all of these problems in the teachings of Rasulullah (S.A.W) and in his noble life. Hence it is very important to prepare a framework in the light of Seerah and adopt it accordingly in this very important part of life. In the article under reference, Muslims Political deterioration in the modern era and a review of its remedy is to be presented in the light of Seerah.

Atmospheric Dispersion and Consequence Modeling of Radiological Emergencies

The Medium Term Development Frame Work (MTDF) 2005-10 by Planning Commission Government of Pakistan states the policy for power sector in which it puts a greater emphasis on nuclear power resources by increasing its share from currently 425 MW to 8800MW by 2030. With the increase of nuclear share in the overall national energy mix, a corresponding environmental impact and nuclear safety analysis are equally important. These are usually taken care of by Primary Safety Analysis Report (PSAR) of a proposed nuclear power plant. The PSAR of any proposed nuclear power plant involves the assessment of a hypothetical accidental release of radionuclides in the atmosphere as set forth by US-NRC and PNRA such as those given as criteria for preparation and evaluation of radiological emergency plans and preparedness (10CFR100, PAK/910). Modeling atmospheric dispersion (both transport and diffusion) is the first step of such assessments. The objective of this work is to determine a more precise modeling methodology that can better predict the radiological consequences in terms of radionuclide concentration and doses compared to Gaussian dispersion approach that is based on assumptions such as uniform turbulence, flat topography and non-variant wind speed with time and space. The research goal was achieved by developing two broad strategies on the basis of Lagrangian approach. The first strategy is an effort to provide a simple answer to the complex problem. This methodology makes use of empirical parameterization of meteorology which serves as input for dispersion calculations by Lagrangian Stochastic Particle Model (LSPM). But the beauty of approach is its capability to capture complex atmospheric phenomenon like wind directional shear. This approach was used to study hypothetical accidental release of radionuclides in nocturnal atmosphere which generates maximum wind directional shear. The results of dispersion in terms of dispersion coefficients were in good comparison with that of experimental findings in the available literature. The resulting ground level concentrations of radio-nuclides and radiological dose contours were also compared with those based on approach analogous to Gaussian Plume Model (GPM). The exercise proved that how misleading results would be if we ignore wind directional shear in stable atmosphere. The second approach is based on a state of the art solution. It involves the coupling of an Eulerian meteorological model (RAMS) with LSPM. The meteorological model is responsible to provide meteorological input to LSPM at each grid point and at each time step. This computational technique was used to simulate a hypothetical accident at a proposed site for Nuclear Power Plant. The meteorological output of the modeling system was compared with observed values. The comparison proved the efficacy and reliance of the approach. This computationally intensive but effective strategy is quite capable of supporting a real time decision making system for tackling nuclear emergency.
