اسد اﷲ کاظمی

اسد اﷲ کاظمی
گزشتہ مہینہ ایک اور حادثۂ وفات جناب اسداﷲ صاحب کاظمی کاپاکستان میں پیش آیا جہاں وہ اپنے اعزاسے ملاقات کی غرض سے دو ماہ پیشتر ہی گئے تھے۔مرحوم نہایت قابل اور بڑی خوبیوں کے انسان تھے۔انگریزی نہایت عمدہ لکھتے تھے ۔تعلیم کے بڑے ماہر تھے۔اترپردیش میں تعلیم کے اسسٹنٹ ڈائریکٹر رہے اس کے بعد یونیسکو کی طرف سے کم وبیش آٹھ برس تک حکومتِ عراق کے مشیر تعلیم کی حیثیت سے بغداد میں قیام پذیر رہے۔ اس سے سبکدوش ہوکر الہ آباد میں مقیم ہوگئے۔اسی زمانہ میں سنٹرل وقف کونسل کی طرف سے مسلمان طلباء کے لیے پرائمری ایجوکیشن کانصاب بنانے کے لیے ایک کمیٹی کی تشکیل ہوئی تو اگرچہ اس کی صدارت راقم الحروف کے سپرد تھی لیکن واقعہ یہ ہے کہ کاظمی صاحب مرحوم نے کمیٹی کے ایک ممبر کی حیثیت سے نہایت اہم اور مفید رول اداکیا۔وہ برابر کمیٹی کی میٹنگس میں شریک اوراس کی کارروائیوں میں پوری دلچسپی اورسرگرمی سے حِصّہ لیتے رہے اور کمیٹی کی رپورٹ اورنصاب بہت کچھ انہیں کی رہنمائی کا نتیجہ ہے۔بغداد میں رہ کرقرآن مجید اوراسلامیات پرکتابوں کے مطالعہ کابڑا شوق پیدا ہوگیا تھا۔اخلاقی اعتبارسے نہایت شریف ،بلند نظر اور بیحد ہمدرد وملنسار بزرگ تھے۔جب کبھی ملاقات ہوتی تھی راقم الحروف سے ہمیشہ قرآن مجید کے کسی حکم یاکسی آیت پرگفتگو کرتے تھے۔اﷲ تعالیٰ نے ان کو حسناتِ دینی و دنیوی سے نوازا تھا۔اب آخرت میں بھی اﷲ تعالیٰ ان کو ابرار وصلحا کامقام عطافرمائے۔ آمین۔ [ اکتوبر ۱۹۷۱ء]

 

Why Criminologists Study Journalism?

‘Media is situated within, and fully interwoven with, many other social practices, to the extent where crime and media representations are inseparable’. Criminologist must, however, be alert to the ways in which media create perceptions in order to understand that things are not as always as they are presented. Criminologist has to be a well-versed scholar on the subject of media practices to tread fuzzy area between the news and propaganda and to identify the instances of media coverage of crime as the major culprit for the increase in crime through its redefinition; and for the increase in pessimism through projecting only dark things in much darker light as good news is bad news for media. Awareness of media practices helps criminologist to understand the reasons for separate feeds so can be used for different content of several newspapers to realize truth; and to understand the failure of media to publicize moral dilemma because of its failure to offer rational and duly informed societal response. Criminologist is to be media scholar to know that news is not necessarily about events those transcend crimes and there does exists the standoff between moral panic and realism and separation of cause and effect and the addition of newness to news and exceptionalization of crime; and crime representation can be for the marginalization of some groups.

Biotranformation of Selected Pollutants Using Biofilm Forming Bacteria

Environmental contamination due to improper dumping of industrial effluents and its toxicological manifestations has been recognized as major cause of public health risks, especially in developing countries. It has urged the scientific community to focus on various approaches to remedify their impacts.Keeping in view, the costs and generation of toxic byproducts related to conventional remediation strategies, there is a continuous need to look for environmentally safe technologies. Biological techniques (bioremediation) using microbial biomass and their biomolecules/products offer better treatment of contaminants compared to physical and chemical methods. Such potentials of biofilm forming bacteria and their biopolymers were investigated in present work. Bacteria from biofilm samples were isolated and screened for biofilm formation and decolorization of chemically variable dyes. All bacterial isolates were Gram negative, facultative anaerobes and mesophiles. They conferred resistance to multiple heavy metals including cadmium (100-1000 mg L-1), chromium (7001000 mg L-1), copper (600-1000 mg L-1), lead (1000 mg L-1), iron (1000 mg L-1) and nickel (200-600 mg L-1). Selected isolates with potentials to degrade/transform xenobiotic compounds were characterized at molecular level and identified as Staphylococcus sp. MB377, Bacillus subtilis MB378, Klebsiella oxytoca MB381 and Klebsiella pneumoniae MB398.Bacterial isolates showed the capability of decolorizing and degrading different dyes (Eriochrome black T, Congo red, Malachite green) in the presence and absence of glucose. Bacillus subtilis MB378 was most efficient in degrading these dyes up to 65-90% in presence of glucose. Optimum conditions for decolorization of Congo red dye were pH 5 (Klebsiella pneumoniae MB398), Eriochrome black T dye pH 8 (Bacillus subtilis MB378) and Malachite green dye pH 9 (MB392). While highest decolorization rates of Congo red dye were observed at 37˚C (Klebsiella pneumoniae MB398), Eriochrome black T dye at 30˚C (Bacillus subtilis MB378) and Malachite green dye at 30˚C (MB392), respectively. UV-VIS spectrophotometric & FTIR analysis, high performance liquid chromatography (HPLC) and gas chromatography (GCMS) further confirmed the possible degradation/transformation of dye molecules into respective metabolites.Assessment of simultaneous removal of dye and selected metals by biofilm forming bacteria showed efficient decolorization of Malachite green dye in presence of cadmium, copper and xxiv chromium (up to 79.65 & 88.07%, 79.35 & 93.18%, and 81.63 & 90.32%) by Staphylococcus sp. MB377 and Bacillus subtilis MB378, compared to individual dye molecules. Bioaccumulation yield of copper in combination with Malachite green dye was 30.88 mg L-1 (Staphylococcus sp. MB377), 31.22 mg L-1 (Bacillus subtilis MB378), while for chromium it was 29.88 mg L-1 (Bacillus subtilis MB378). Maximum chemotactic indices were recorded in the presence of glucose for Congo red by MB387 (1.37), Methyl orange by MB391 (0.97), Malachite green by MB391 (0.87) and Eriochrome black T by MB377 (0.74). Highest chemotactic potentials of Klebsiella oxytoca MB381 towards chromium (83.14), Staphylococcus sp. MB377 towards lead (81.23), MB392 towards cadmium (0.74) and Staphylococcus sp. MB377 towards copper (0.47) were recorded through capillary assay in the presence of glucose, while chemotactic response towards dyes and metals declined in the absence of glucose. Biopolymeric substances (EPS) were rich in carbohydrate contents and also harbored fairly good antimicrobial activities against target bacteria with inhibition zones ranging between 0.8-1.91 cm. FTIR spectroscopic analysis showed that these polysaccharides were comprised of proteins, carbohydrates, alkyl halides, nucleic acids, various hydrophilic and hydrophobic functional groups. SEM and XRD analysis revealed compact and crystalline nature of EPS. EPS from Staphylococcus sp. MB377, Klebsiella oxytoca MB381 and Klebsiella pneumoniae MB398 formed 67.71, 61.25 and 60.46% stable emulsions. EPS from Klebsiella pneumoniae MB398 gave highest emulsion retention values for Canola oil (1.330±0.045), Kerosene oil (1.261±0.251) and n-Hexane (0.794±0.120). EPS from Bacillus subtilis MB378 removed 96.09% of cadmium in combination with Malachite green, with an adsorption rate of 0.98 mg g-1. While 90.86% of copper removal in the presence of Malachite green dye was observed for EPS from MB392, compared to individual metal ions. EPS from Staphylococcus sp. MB377 removed 85.10 and 84.76% of Malachite green in combination with cadmium and chromium compared to dye molecules alone. FTIR spectra further confirmed that the reactions and complexation of dye in presence of metals with charged or ionizable functional groups of EPS had facilitated their adsorption and accumulation on to the surfaces of EPS. Complete genome sequencing of Staphylococcus sp. MB377 and Bacillus subtilis MB378 showed that each genome possessed significantly diverse structural and functional features. Both these strains had multiple genes involved in biofilm formation, adhesion, xxv exopolysaccharide production and chemotactic responses. Genes for metal resistance (Cd, Cr, Cd/Zn/Co, Cu) and reduction of arsenic were also annotated in the genomes of Staphylococcus sp. MB377 and Bacillus subtilis MB378, respectively along with multidrug efflux and transporting systems. These strains also possessed wide range of metabolic activities for effective catabolism and detoxification of xenobiotic compounds. Stress induced/response proteins were indicative of defense mechanisms and ability of bacteria to survive in diverse environmental conditions. Annotated genes encoding for various enzymes (dioxygenases, acylphosphatases, nitroreductases, tautomerase, laccase-like multicopper oxidase and oxidoreductases) indicated the potentials of these strains for utilizing and degrading different aromatic compounds and dyes.The diversity and potential of biofilm forming bacteria to adapt in diverse environmental conditions was recognized in present study. The results further supported present bacteria and their biomolecules as most potential/effective candidates for the remediation of polluted sites.
