Petroleum waste is composed of some hazardous compounds, which may affect the terrestrial and aquatic ecosystem. These compounds are persistent in the terrestrial environment and may take several years prior to be degraded naturally. Therefore, some environmental friendly techniques are needed to be adopted to speed up the natural degradation process of such compounds. Biological technique is one of the most beneficent technique used to speed up the natural degradation of petroleum compounds across the world. Further improvement in biological technique using nano particles is also gaining scant attention to enhance the natural degradation process of petroleum waste. The proposed study aimed to develop an economic, rapid and environment-friendly remediation method for the oil companies to rehabilitate petroleum waste contaminated soil which could be achieved through developing microbial based technique. This study described further improvement in the bioremediation method, using mangrove roots powder with and without silver nitrate nanoparticles to accelerate the degradation of petroleum waste contaminated soils at various depths.) Objective 1. The present study was aimed to examine the difference in the soil physicochemical as well as geochemical characteristics between control and petroleum waste contaminated (with respect to distance and depth). For that purpose, three oil fields (Chanda, Nashpa and Mela) from Kohat Plateau and four oil fields (Kal, Chaknaurang, Messakaswal and Sadqal) from Potwar Plateau were selected. Soil samples were collected from surface 0-15cm (‘A’ horizon) and subsurface 15-30 cm (‘B’ horizon) and 30+cm (‘C’ horizon) for physicochemical and geochemical analysis (soil texture, pH, EC, organic matter, organic carbon, inorganic carbon, major elements: Al, Ca, K, Mg, Na, P, and trace elements such as Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn). Some sites had no ‘C’ horizon iv therefore information about such sites is restricted to only A and B horizons. The results of this study show that the soil of Kohat Plateau was sufficient in calcium and sodium. However, Phosphorus and potassium were found to be deficient in such soils. Whereas, Aluminum was found to be marginal in all soils. Petroleum waste contamination poses no effect on the lateral and horizontal distribution of all major elements in any of the soil profile of both the study areas. However, calcium was found to be decreases with increase in depth in a soil profile and distance from the contamination source. This suggests that petroleum waste may increase the concentration of Ca in the soil. Petroleum waste contamination poses no effect on major elements concentrations in all soils. Organic carbon content increases with the petroleum contamination except for a few exceptions. Total Cr, Zn and Pb concentration in all soils of both the study areas remained within the permissible limit. However, the total Cu, Mn, Ni and Cd concentration in all soils of both the study areas exceeds the permissible limit. Whereas, the concentration of Co in all soils of both the study areas was also above the permissible limit. Moreover, Copper and Nickel were found to be at elevated level in petroleum waste contaminated soil. The results of contamination factor show that Cd, Cr, Cu, Co, Mn, Ni, Pb and Zn depicts low to moderate contamination in the soil of Kohat and Potwar Plateau. However, enrichment factor show that Cr, Pb and Zn were in depleting range, whereas, Co, Cu and Ni were in normal range, However, Cd was significantly enriched and Mn was unusually enriched. Zinc and Nickel were in the category of deficient to minimal enriched, which indicated their occurrence in the soil was natural. Cadmium poses moderate risk to the ecological system whereas all the other trace elements (Cr, Cu, Co, Mn, Ni, Pb and Zn) may cause low ecological risk to the environment. Pearson correlation shows positive correlation of Ni with Cd, Cr, Co, and Pb except for Zn. Objective 2. To identify and isolate various genera of micro-organisms capable of degrading hydrocarbons at various depths of the soil profile in petroleum waste-contaminated sites, soil samples were collected from surface 0-15cm (‘A’ horizon) and subsurface 15-30 cm (‘B’ horizon) and 30+cm (‘C’ horizon). Around 18 bacterial strains were isolated from horizon A, B and C. Bacillus pumilus, Bacillus sp. Exiguobacterium aurantiacum, Bacillus megaterium, Lysinibacillus fusiformis,and Bacillus altitudinis) were isolated from surface soil. Whereas, Bacillus subtilis, Bacillus licheniformis, Lysinibacills fusiformis, Bacillus firmus, Bacillus sp., Bacillus oceanisediminis, Bacillus subtilis, Fictibacillus barbaricus, Bacillus sonorensis, Bacillus amyloliquefaciens, Lysinibacillus sphaericus were isolated from subsurface soil of petroleum waste contaminated soils. Objective 3. To prepare a microbe-based formulation for the remediation of petroleum waste-contamination, the uncontaminated/control soil was initially spiked with 50% petroleum waste. Then, the spiked soil was treated with fertilizer, consortium, mangrove root powder and silver nanoparticles alone or in combination (T1-T7). To evaluate the efficiency of the abovementioned treatments (at surface or subsurface soil) and to choose the best suitable treatment for the degradation of TPH, two lab experiments A (in aerobic conditions) and B (anaerobic conditions) were conducted for an incubation period of 240 days. The rate of degradation of TPH and total bacterial population was monitored regularly at various days of incubation (i.e., 0, 5, 20, 60 and 240). The results of the present study show that silver nanoparticles alone or in combination with consortium or/and fertilizer had no pronounce effect on the degradation of TPHs. Thus, cannot be considered suitable to be applied commercially to facilitate bioremediation. Whereas, consortium degraded a significant amount of TPH even in the beginning of incubation period. In addition, the efficiency of fertilizer in the degradation of TPHs was also observed at the end of incubation. Similarly, Total bacterial population was increased in the presence of fertilizer and consortium. Whereas, silver nanoparticles did not increase the total bacterial population. Thus, bioremediation is considered to be an effective technique to degrade TPHs than nano-bioremediation. Like silver nanoparticles, mangrove root powder (alone or in combination with consortium and/or fertilizer) did not show any positive or negative impact on the degradation of TPHs as well as on the total bacterial population. Thus, mangrove root powder is not suitable to enhance bioremediation of petroleum waste contaminated soils.
مولانا ظفر علی خان افسوس ہے کہ گذشتہ مہینہ ۲۷؍ نومبر کو مولانا ظفر علی خان نے بھی سفر آخرت کیا، ان کی موت سے ایک اہم تاریخی یادگار مٹ گئی، وہ پرانے نامور علیگ اور مولانا شبلی مرحوم کے شاگرد تھے، نئی نسل ان کی اہمیت اور ان کے کارناموں کا اندازہ کر ہی نہیں سکتی، ایک زمانہ میں پورا ہندوستان ان کی شہرت سے گونجتا تھا، اور سیاست و صحافت، انشاء و خطابت، سخن وری سخن سنجی ہر میدان میں ان کا طوطی بولتا تھا، وہ اپنے زمانہ کے بڑے جری، دلیر، پرجوش اور سرفروش لیڈر، شعلہ بیان خطیب، سحرطراز ادیب اور قادر الکلام و نکتہ سنج شاعر تھے، ان کے قلم اور زبان دونوں میں سیلاب کا جوش و خروش تھا، اپنی تحریر و تقریر سے طوفان بپا کردیتے تھے، ملک و ملت کی راہ میں ان کے بڑے کارنامے اور بڑی قربانیاں ہیں، ان کے زمانہ میں کوئی مذہبی و ملی اور قومی و سیاسی تحریک ایسی نہ تھی، جس میں ان کا سرگرم حصہ نہ رہتا ہو، وہ اس زمانہ میں انگریزی حکومت سے ٹکرلیتے تھے، جب اس کے جلال و جبروت کا آفتاب نصف النہار پر تھا، اور بڑے بڑے لیڈر اعتدال سے باہر قدم نکالنے کی ہمت نہ کرتے تھے اور اس راہ میں جانی و مالی ہر قسم کی قربانیاں کیں اور برسوں قید و بند کی مصیبتیں جھلیں۔ ان کا اخبار زمیندار اپنے زمانہ کا اردو کا سب سے مشہور اور ممتاز اخبار تھا، ہندوستان خصوصاً مسلمانوں کی بیداری میں اس کا بڑا حصہ ہے، اس نے جس قدر مالی نقصان برداشت کیا ہے، اس کی مثال اردو اخباروں میں نہیں مل سکتی، زمیندار کا ادارہ صحافت کی مستقل تربیت گاہ تھا، پنجاب کے اکثر اخبار نویس اسی ادارہ کے تربیت یافتہ ہیں، قادر الکلامی میں اکبر کے...
The UK is a Christian majority country with several minority religious groups like Muslims, Hindus, Jews and Sikhs who have been living there for a long time. All faith groups have their own laws. Likewise, Muslims also have their specific laws called “Sharī’ah law” or “Muslim Family Law”. This paper attempts to represent a prospect of how Islamic law deals with the issues faced by the Muslims in England and Wales. There are many “The Islamic Shari’ah Council (ISC)” and “Muslim Arbitrational Tribunal (MAT) to solve the family concerns in England and Wales, for instance, marriage, child custody, divorce and other issues related to their matrimonial life. These councils play a prime role in implementing Islamic law among Muslims in Britain. Since ISC and MAT play a crucial role in applying Islamic law, it will be the focusing component of the paper. This study examines how ISC and MAT resolve the legal problems of the Muslim families and to which extent sometimes it is allegedly not compatible with England and Wales's domestic legal settings. Moreover, the main aim and object of the paper is to find out the internal functions and the processes of the Islamic Sharī’ah Council and Muslim Arbitration Tribunal in England and Wales
The present breeding study was planned to cross the various indigenous breeds for developing a hybrid rural breed which can live as a scavenger bird under the harsh rural conditions with improved economic traits. The study was conducted in three independent phases. In first phase, breeds comparison was performed for Desi, Fayoumi and Rhode Island Red chickens. Maximum hatchability was recorded in Fayoumi followed by RIR and Desi. The average day old weight was seemed highest in RIR, intermediate in Desi and lowest in Fayoumi. The poor feed conversion was observed in Desi breed and better feed conversion was recorded in RIR breed. The early age of sexual maturity was recorded in Fayoumi followed by RIR and Desi. The RIR chickens had highest egg production followed by Fayoumi and Desi chickens. The all internal egg quality parameters were significantly higher in RIR than Fayoumi and Desi breeds except shell and yolk thickness. In second phase, the performance of RIR and Fayoumi chickens were examined with their reciprocal crossbred chicks. Higher hatchability was noticed in crossbred chickens than their parents. The average day old weight was highest in RIR and FIRI (Fayoumi male × RIR female) followed by RIFI (RIR male × Fayoumi female) and Fayoumi. The average weight gain and daily feed intake was higher in FIRI chickens than RIFI crossbred chickens. The better FCR and liviliability were observed in both crossbred chickens during growing phase. Morphologically the two crossbred chicken (RIFI and FIRI) showed variation in all characters. The dominant skin colour for both crossbred chickens was white while the egg shell colour was chalky white. The major feather colour in RIFI was brown with xxblack spots, while black & white in FIRI. Shank colour was 100% yellow in RIFI and 100% black in FIRI. The dominant comb type in the whole ecotypes was the single one. The heterotic effects on body weights were significant in both crossbred chickens except at day old and gradually increased to 10.27% at 3 weeks in RIFI and 19.45% at 8 weeks in FIRI and then declined to 5.50% at 4 weeks in RIFI and 8.70% at 9 weeks of age in FIRI. Results for reciprocal crosses in this research study revealed that FIRI had high heterotic percentage at 10 weeks of age to get hybrid vigor in growth traits. These results may helpful for the poultry breeders to cross these two breeds (Fayoumi X RIR). The egg production was highest in FIRI followed by RIFI, RIR and Fayoumi chickens respectively. In conclusion, the crossbred chickens of Fayoumi male and RIR female (FIRI) showed better performance in all traits than crossbred chickens of RIR male and Fayoumi female (RIFI). On the basis of above results, crossbred females of FIRI were retained and mated to the third breed (Whitel Leghorn) for further improvement in production performance in the subsequent trial. In third phase, crossbred chicken with proposed name; Rural Leghorn (RLH) breed was developed by crossing White Leghorn male with FIRI females. The progeny as RLH chickens contain White Leghorn (50%), RIR (25%) and Fayoumi (25%). In this phase, according to research plan, only growth data regarding RLH-G1was also recorded and compared with performance of FIRI, RIFI and RLH breeds. The average day old weight was highest in RLH followed by RLH-G1, FIRI and RIFI. The results showed that RLH and RLH-G1 crossbred chickens had lowest mortality and were shown heavier in weight at 20 weeks of age. The dominant skin colour for the crossbred chicken was white for RLH and xxiRLH-GI while the egg shell colour was light brown in RLH. The major feather colour in RLH was white whereas in RLH- G1 ratio of white and colored birds was 75:25 respectively. Shank colour was 100% yellow in RLH whereas 84% white in RLH-G1. The heterotic effects on body weights were significant in both crossbred chickens except at day old and gradually increased to 8.55% at 7 weeks in RLH and 26.5 in RLH-G1 and then declined to 4.28% at 9 weeks in RLH where as 22.67 in RLH-G1. The highest egg production was found in RLH (72.2%) followed by FIRI (60%), RIFI (54%), RIR (41%) and the Fayoumi chickens (36%). As far as the rate of lay (no. of eggs per hen) is concerned, RLH scored higher (253) than those of FIRI (198), RIFI (178), RIR (141) and Fayoumi (123) chickens. In conclusion, newly evolved RLH chicken gained better body weight than Fayoumi and Desi, moderate than RIR and FIRI chickens with lower mortality. The RLH chicken showed better performance in all egg traits than parents and other crossbred chickens of RIR male and Fayoumi female. The growth performance of RLH- G1chicken was better than reciprocal crosses of RIR and Fayoumi chicken and at par with RLH chicken.
