المبحث الأول: أصلها ونسبها
وُلدت بروین شاکر في بیتِ عزِ وشرفٍ وأصل أجدادھا من الھند، وھي من بیتِ علم وثقافۃ وشعر وأدب، فقد تعلّم جد الشاعرۃ (پروین شاکر) السید أبو الحسن في (پٹنہ) بتنہ في مسجدِ شمس الھُدیٰ[1]، وکان لہُ ثمانیۃ أولادٍ وبنتان، وکان والد بروین شاکر أصغر أولادہِ، وھو شاکر حسین، وکان یحب الشعر منذ صغرہ، ثم انتقل شاکر حسین من بتنہ إلی کراتشي، یبحث عن مستقبل رائعٍ، ثمّ تزوج بفتاۃٍ إسمھا أفضل النساء وھي والدۃ بروین شاکر[2]۔
ولادتها
ولدت لسید شاکر حسین إبنتُہ الأولی في 12 مارس 1950م التي سماھا نسرین[3]، وفي 24 نوفمبر 1952م ولدت ابنتہُ الثانیۃ والتي سُمیت ب (پروین بانو)[4]، وبعدھا نسبتاً إلی أبیھا سمیت ب(پروین شاکر) وأسمھا في شھادۃ الماجستیر (پروین بیگم)[5]، وأھلھا کانوا یسمونھا بالمحبۃ والدلع ب(پارو). تقول ھي بنفسھا أن (پارو)، و (پارا) أسماء الدلع والدلال کانوا أھلی یسمونی بھا (Nick Name)[6]۔
تعلیمها
کان تعلیم بروین شاکر الإبتدائی في(حي الرضویۃ) في (المدرسۃ الإسلامیۃ) في کراتشي مع شقیقتھا نسرین، أمّا بروین فکانت طالبۃ مجتھدۃ منذ طفولتھا، فقد سُجّلت في المدرسۃ في الصف الثالث ولکن بجھدھا ومحاولتھا ألحقت بأختھا نسرین في الصف الخامس۔
بعدما أکملت الشاعرۃ دراستھا الإبتدائیۃ ألحقت بمدرسۃ في (Sun rising school) [7] ثم أخذت الشاعرۃ تشارک في مختلف العلوم والمسابقات بجانب دراستھا وتفوقھا الدراسي، المسابقات المختلفۃ والمباحثات أضافت في فھمھا وفطانتھا وأیضاً شارکت في الأعمال الأدبیۃ المدرسیۃ مما ساعدھا علی زیادۃ ثقافتھا وأدبھا۔
ثم بدأت الشاعرۃ تُطالع کتب الأدب والمذھب والقصص الدینیۃ وقد فازت في ھذہ المدرسۃ بجائزۃِ في...
Kamal Ahmed Rizvi (1930-2015) is among the very first people to give credence to Pakistan Television Urdu drama. He is one of the first rate and accomplished dramatists, director, actor, as well as a visualizer. In the world of drama he has a very versatile presence. He is also one of the first persons to affect the transition of the Urdu drama from stage to television, as such, he is an indelible name in the history of our art and theatre. Whenever Pakistan Television drama is mentioned, his name can never be omitted; or if its history is written, it shall be incomplete without reference to him. If Kamal Ahmad Rizvi is called an institution by himself, it shall not be wrong, because he is a creative writer, a translator, a director and a producer; and until now there has been no other individual with like qualities in the history of Pakistan Television, and this is his mark of distinction. ______
The current study reveals various features that can affect the gasification process to improve syngas quality and yield. A comprehensive study was carried out using a 24 kW downdraft gasifier to evaluate the effect of uniformly distributed air in the oxidation zone, additional throat on the gasifier internal thermal profile distribution and the overall gasification process. The effect of biomass moisture, equivalence ratio, gasifying agent type and pre-treatment of the gasifying agent on producer gas yield and composition were also evaluated. The gasifier unit was equipped with cyclone separator, wet scrubber, water gas separator, biomass filter, auxiliary filter, cooling tower and vapour compression refrigeration system. The maximum flow rate of producer gas was found to be 90-104 m3h-1 under the biomass feeding range of 30-40 kgh-1. When corn cobs and waste wood (carpenter waste) with moisture content from 5-30% were used as feed stock, with 70ºC air as the oxidizing agent, the energy value of the producer gas obtained was 6.31 and 6.66 MJm-3, respectively. The heating value was improved to 6.72 and 8.43 MJm-3 when using 150ºC air-steam mixture as the gasifying agent, with the optimum equivalence ratio of 0.30. The Methane, Hydrogen and Carbon monoxide concentration (on volume basis) were found to be 6.20, 19.32 and 21.00%. The average amount of syngas produced from one kg of corn cobs and waste wood were 2.94 and 2.62 m3, while the average amount of tar produced was 2.2 and 1.8 gNm-3 respectively. The efficiency of cleaning and cooling system were found to be 86.81 and 92.06%. The experimental research concluded that uniformly distributed air in the combustion zone as an interconnected parameter with biomass moisture level, type of gasifying medium and pre-treatment/pre-heating of gasifying agent played a vital role in affecting the syn gas production and composition.
