چودھری خلیق الزماں

چودھری خلیق الزماں
افسوس ہے کہ گزشتہ مہینہ چودھری خلیق الزماں مرحوم کا کراچی میں انتقال ہوگیا، مرحوم ان لوگوں میں تھے جن کی پوری زندگی سیاسی اور قومی کاموں میں گزری، سیاست کا چسکا ان کو طالب علمی ہی کے زمانہ سے تھا، چنانچہ جنگ بلقان کے زمانہ میں ہندوستان سے جو طبی وفد ڈاکٹر انصاری مرحوم کی قیادت میں ٹرکی گیا اس میں جو نوجوان شامل ہوئے تھے ان میں ایک چودھری صاحب بھی تھے، کئی مرتبہ لکھنو میونسپلٹی کے چیرمین ہوئے ان کی چیرمینی کا دور ایک یادگار دور تھا، اسی زمانہ میں خلافت اور ترک موالات کی تحریک شروع ہوئی، اس میں اس سرگرمی سے حصہ لیا کہ صوبے کے لیڈروں میں ان کا شمار ہونے لگا، ایک مدت تک کانگریس میں رہے، پنڈت موتی لال کے معتمد علیہ اور جواہر لال کے خاص رفقاء میں تھے، کانگریس میں بھی نمایاں مقام حاصل کیا، چنانچہ ۱۹۲۹؁ء میں جب کانگریس کے لیڈروں کی گرفتاری کا سلسلہ شروع ہوا تو آخر میں ان کو کانگریس کا ڈکٹیٹر مقرر کیا گیا تھا۔
پھر مسلم لیگ میں شامل ہوگئے اور پاکستان کی تحریک میں چند دنوں میں آل انڈیا لیڈر کی حیثیت حاصل کرلی چنانچہ پاکستان کے بانیوں میں ان کا شمار ہوتا ہے، قیام پاکستان کے بعد کراچی چلے گئے، یہاں بھی ان کو بڑے بڑے عہدے حاصل ہوئے مختلف اوقات میں مسلم لیگ کے صدر مشرقی پاکستان کے گورنر اور انڈونیشیا کے سفیر مقرر ہوئے مگر مسٹر جناح ان سے خوش نہ تھے اس لئے وہ پاکستان کی سیاست پر اثر انداز نہ ہوسکے اور آخر میں گوشہ نشینی کی زندگی اختیار کرلی تھی اور اسی پر ان کا خاتمہ ہوا، چودھری صاحب کی زندگی قلندرانہ تھی، وہ وکیل تھے، ان کے ماموں اور خسر مولوی محمد نسیم صاحب لکھنو کے چوٹی کے وکیل اور...

چائنہ نمک کی حلت و حرمت کا تجزیاتی مطالعہ

Monosodium Glutamate is the scientific name of Chinese salt, which also called Ajinomoto. Monosodium Glutamate was first discovered by the Japanese chemist Ikeda Kibunae in 1908. The MSG was firstly derived from seaweed. Later on MSG was got from meat, gluten, and vegetables etc. It can be derived from Najas ul ‘ain and Gher Najas ul ‘ain things. If it was got from Najas ul ‘ain, then there is a question about MSG that is it halal (permissible/ lawful) or haram (non-permissible/unlawful). This research in this article is concluded that if the culture of MSG is halal or the proper Istihalah has been done in Najas; MSG will be halal (permissible/ lawful). However, where no such details are available about the culture of MSG, it should be avoid, although it cannot be declared haram as per Islamic Jurisprudence rules.

Experimental Investigation and Mathematical Modeling of a Low Energy Consuming Hybrid Desiccant Cooling System for the Hot and Humid Areas of Pakistan

This experimental and simulation study investigates the potential of using a solar assisted hybrid desiccant cooling system (SHDCS) for air conditioning applications for Pakistan. A review of literature reveals that compared to the conventional vapour compression cycle this cycle could offer saving in overall primary energy. Since the cycle is based on supply of conditioned ventilation air it has significantly lower environmental impact. A gas fired hybrid desiccant cooling test rig has been installed at the Energy Conservation Laboratory NED to study the performance of various components. These experiments enabled understanding of the system and helped develop effect of individual components on the system performance. Important parameters of system components established from the experiments were used as input to the TRNSYS simulation model. The simulation studies have been based on a well established transient energy software TRNSYS. Specific to this work a mathematical model of Modified Cooler was prepared from basic principles and added as module to TRNSYS. Addition of this component resulted in an increases of the COPp-s by a factor of 1.065 for the weather of Lahore. Besides COP; all system parameters showed an improvement due to the addition of this component. Six case studies based on SHDCS have been performed for Karachi and Lahore. The results so obtained established that the advantage of using SHDCS depends on the climatic conditions. SHDCS offers considerable promise for Lahore i. e., it shows that of the seven month summer cooling season the desiccant cooling system alone suffices for three month – April, May and October. However for Karachi summer, characterized by high humidity, SHDCS does not provide acceptable temperature and humidity conditions without auxiliary air conditioning. The source of thermal energy needed for regeneration plays an important part in the overall success of the desiccant cooling scheme. To reduce the use of conventional energy, in this case natural gas, a solar collector has been included in the study. Micro analysis of the flow and heat transfer phenomenon taking place inside inclined solar air collector was studied using CFD software, which demonstrated that low heat transfer between air and absorber can be improved by using staggered fins. It was also shown that the fin configuration coupled with low flow velocity helped increase heat transfer in the absorber duct by increasing heat transfer area, mixing and residence time. Energy, economic and environmental impact of the solar collectors was also studied and payback periods for energy, Carbon emission and monetary investment have been found to be 1.5 years, 1 year and 14 years respectively. The success of the desiccant cooling system is strongly associated with cost of the thermal energy. Combined heat and power systems offer an opportunity of providing this energy at no additional cost. The latter study has been suggested to be taken up as future work.
