انا

حالات کی اک ضرب نے دیکھو
ایسی رُت بھی کھولی تھی

کہ ہم تم جو یکجاں بہت تھے
دور بہت جا بیٹھے تھے

دل کو پر گماں تھا یہ
غلط نہیں ہے تو پر تجھ سے

اس رُت میں غلط ہو رہا ہے
گردش کا یہ کھیل ہے شاید

دل کی ان زمینوں پہ
جو فاصلے بو رہا ہے

اس سب میں تو بھی تھک گئی تھی
چلتے چلتے رُک گئی تھی

میں بھی ٹھیک تھا اپنے تئیں
رُک گیا تھا میں بھی وئیں

پر تجھ سے یوں بچھڑنے کو
میں نے بہتر سمجھا مرنے کو

اُٹھا میں اپنے کمرے بند سے
تیرے پیروں میں انا دھرنے کو
میں آیا سب ٹھیک کرنے کو

بیسویں صدی کی معروف بائبلوں کے تصور جہنم کا تجزیاتی اور بیانی مطالعہ

Since Eschatological Sciences are playing a vital role in shaping theologoy and philosophy of the major world religions. The concept of Hell is conceived as a place where human actions are judged and then rewarded accordingly on the Day of Judgment. Aim of the paper is to find out how the terminlolgy of Hell and its concept is evolved in several versions of the English Bibles of the twenthith century. The paper highlighted that due to numerous English translations of the Bible in ninthenth and twentheith century, not only caused amalgamation in supplementary concepts but also caused change in the concept of Hell as well. This resulted confusion in other eschatological dogmas evolved around the subject. Keeping in view its evolved concept over the history the research shows how it affected other related concepts to it.

Biodiesel Production by Microalgae Cultivation Through Conversion of Industrial Carbon Dioxide Co2

Biofuel production is widely deliberated to be one of the most sustainable alternatives to the non-renewable petroleum fuels and used as feasible means for environmental and economic sustainability. Biological capture of carbon dioxide by photosynthetic unicellular microalgae is an attractive technology because it is scalable and efficient mean to yield renewable energy source i.e. biodiesel. Microalgae, a third generation feedstock for biofuel, can be grown on non-arable land in fresh, brackish or saline water and with higher areal productivities than any other land-based crops. In particular high productivities are achieved during cultivation when coupled with an additional carbon dioxide supply; for every kilo grams of dry biomass approx. 1.83 kg of CO2 is required. In this study five industrial cities of Punjab were selected to identify microalgae strains from industrial areas which provide opportunities to achieve significant reductions in carbon dioxide emissions. Microalgae have been considered for biological carbon capture and sequestration to offset carbon emissions from fossil fuel combustion. Series of factors for carbon sequestration like tolerance of CO2 source (i.e. flue gas), cultivation conditions, inhibiting compounds that come with the CO2 source (e.g. SOx & NOx) and physiochemical parameters such as pH, nutrients, temperature and light, had been studied in this research. The adapting ability of mixed consortia of microalgae was used to tolerate growth in 100% flue gas from an unfiltered coal-fired power plant that contained 11% CO2. Challenges existed in particular around the high SOx and NOx emissions that caused a rapid decline in pH when added to cultures. This required slow adaptation of microalgae over many months, with step-wise increases from 10% to 100% flue gas supplementation, and the maintenance of high phosphate fertilizer levels in the form of 50mM phosphate buffer for flue gas at and above 50%. Concurrently, this led to a selection of microalgae that seem to be particularly well adapted to low pH and high level flue gas supplementation. For two different microalgal consortia, 18S rRNA community profiling and microscopic analyses revealed that, after a rapid decline in biodiversity over the first few months, in particular Desmodesmus sp. was the dominant genus (-79-90%). This novel study demonstrates that upto 100% unfiltered flue gas from coal-fired power generation can be used for algae cultivation. While it is clear that large areas are needed to xviii offset flue gas emission through microalgae, direct comparisons to other carbon sequestration technologies should be made once upscaling, cost reductions and process optimizations are in place. With the implementation of serial passages of over a range of open or closed PBRs this process may contribute towards the development of microalgal-mediated carbon capture and sequestration processes.
