Heavy metal contamination now a day is one of the major global environmental concern and the main sources of heavy metal contamination are either natural or anthropogenic. Industrial wastewater is commonly used for irrigation in most of the developing third world countries. As the number of industries is being increased day by day in the modern world, with this the concentration of heavy metals is also being increased. Several studies have been conducted to elaborate the effects of these heavy metals on living organisms including animals, plants and human. This study aims to isolate, identify some indigenous heavy metal tolerant (HMT) bacteria from textile effluents and to evaluate their biosorptive potential. Three indigenous isolates were screened out showing maximum tolerable concentration (MTC) and multi metal resistance (MMR) to Ni and Co at different levels and were given name as AMIC1, AMIC2 and AMIC3. Molecular characterization confirmed that AMIC1 was (K. variicola, accession number LT838344) while AMIC2 and AMIC3 were (B. cerus accession numbers LT838345 and LT838346 respectively). Biosorptive potential was accessed using Inductively Coupled Plasma- Optical Emission Spectroscopy (ICP-OES) and it was found that AMIC1 reduced (49%, 50%) of Ni after 24 and 48 hours respectively and (68.6%, 71%) of Co after 24 and 48 hours respectively. Similarly AMIC2 reduced (48.4%, 49%) of Ni after 24 and 48 hours respectively and (70.6%, 73.6%) of Co after 24 and 48 hours respectively. AMIC3 reduced (51.8%, 50.6%) of Ni after 24 and 48 hours respectively and (73.2%, 71.8%) of Co after 24 and 48 hours respectively. Fourier transform infrared spectroscopy (FT-IR) was used to analyze the functional groups and overall nature of chemical bonds in bacterial strains while Scanning Electron Microscope (SEM) was performed to detect outer morphological changes in the bacteria in response to metal stress. So it can be concluded that all three bacteria possessed significant bioremediation potential which could be utilized for the development of bioremediation agents to detoxify textile effluents at industrial surroundings in the natural environments in Pakistan.

غلام احمد فرقتؔ کاکوروی

غلام احمد فرقتؔ کاکوروی
دوسرا حادثہ غلام احمد فرقت کاکوروی مرحوم کی درد ناک موت کا ہے، انھوں نے عالم مسافرت میں بڑی بیکسی میں جان دی، بہار کے کسی مشاعرے سے واپس آرہے تھے کہ راستہ میں دفعتہ انتقال ہوگیا، مغل سرائے اسٹیشن پر ٹرین میں لاش ملی، ڈائری سے مرحوم کے نام کا پتہ چلا، پولیس نے ضروری کارروائی کے بعد لاش بنارس کی ایک اسلامی انجمن کے حوالہ کردی جس نے اس مشہور ادیب کو لاوارثی میں دفن کیا، اس دردناک حادثہ پر جتنا بھی رنج والم کا اظہار کیا جائے کم ہے۔
فرقت مرحوم فطری ظریف اور طنز و ظرافت میں شوکت تھانوی کا مثنّٰی تھے، مگر ان کی ظرافت محض ہنسنے ہنسانے کا سامان نہ تھی، بلکہ اکبر کی شاعری کی طرح اصلاحی تھی، اور اس سے انھوں نے بڑے مفید کام لیے، اور اس دور کے ادبی اور سماجی فتنوں کا اپنے رنگ میں بھرپور مقابلہ کیا، اس لحاظ سے وہ ادیب ملت تھے، ان کے قلم میں اتنی طاقت تھی اور انداز بیان اتنا دلکش اور موثر تھا کہ ان کے حریف بھی ان کا لوہا مانتے تھے، وہ ان کے طنز پر تڑپ اٹھتے تھے، مگر اس سے لطف لینے پر بھی مجبور تھے، ان کو لکھنؤ کی ٹکسالی زبان پر بھی قدرت تھی، اور لکھنؤ کی پرانی سوسائٹی کی مصوری میں بھی کمال حاصل تھا، اﷲ تعالیٰ ان کی مسافرت کی موت اور اصلاحی خدمات کے صلہ میں ان کی مغفرت فرمائے۔
(شاہ معین الدین ندوی، فروری ۱۹۷۳ء)

تکفیری جماعت داعش: افکارو اثرات: تجزیاتی مطالعہ

Since the past few years, muslims all over the world are being brutally accused of severe extremism. Many muslims now a days condemn terrorism and extremism and are not willing to connect these terms with the religion Islam. However there are a few who are in favour of these things. Terrorism is basically caused by a number of different acts of brutality. Its actually a chain reaction caused by the conspiracies against Islam, double standards of different super powers and injustice to the convicted and oppressed. Killings of the innocent and unarmed in the name of aggression is some thing which is totally against the Islamic teachings. Things become more complicated and dangerous when such acts of vandalism are done in the name of religion. Although many goals of ISIS are Islam based, however these very goals are achieved through non-Islamic ways. They feel no shame and go against all the ethics and moral values to reach their goals. Hence causing much more damage to their own muslim fellows. Even the cemetries are no more safe. They kill their opponents in the worst possible way and disrespect the dead bodies by kicking and hanging them to the trees. If this situation persists, it is inevitable that ISIS might replace the Halaku Khan and Genghiz Khan is brutality.

Constraint’S Analysis of Agricultural Credit Use: Implications for Poverty Reduction in Pakistan

The study analyzed the constraints faced by the farmers to rural credit by utilizing two household level data sets. The first survey Pakistan Rural Household Survey (PRHS) 2001 was utilized to study the purpose, source structure and utilization of rural credit and; the second which covered nearly 160 households from Sargodha District 2007 was used to calculate the demand and interest rate function by applying Heckman two stage procedures. The focus of this study was to find out the affect of credit constraints of institutional credit on consumption and production pattern of the rural farm households. After measuring the probability of being constrained used to study affect on consumption pattern of farmers who were credit constraint. The frontier production function was used to study the affect of credit constrained and un-constrained farmers. The analysis revealed that agricultural production loan was found as 45.8 percent. ZTBL was providing most of the loan to the farmers for their agricultural needs. The interest was ranging between 10 to 20 percent in all agro-climatic regions. The logit model was applied to determine the nominal interest rate and borrowing function of the farmers. The results showed that the transitory income, predicted interest rate, and farm size were significant. Credit constraints were determined by using Heckman’s two stage procedure. The results showed that the coefficient of education of male household was significant showing that education function as a facilitator to enter into credit market. The farmers faced many constraints namely: lower literacy rate, small and fragmented holdings, uneven access to agricultural extension and information and in ability to obtain adequate irrigation water, less access to agriculture credit institutions, and inequitable distribution of land and water. The results of the frontier production revealed that credit users and non credit users were allocatively inefficient, especially irrigation water. The mean technical efficiency of credit users was 90 and that of non-credit users was 79 percent, respectively. The high technical efficiency of credit users was attributed to better market access to the farmers to new technology through the availability of agricultural credit. The low level of technical efficiency of non-credit users as compared to credit users implied that potential for improvement exists. The high technical efficiency of credit users was safely attributed to credit availability through which farmers have an access to new technology. With respect to policy implication, the study suggested that development and dissemination of low cost and site-specific production technologies for the farmers. In this regard formation of Credit Assessment Bureaus for the risk assessment of the borrowers as it done in urban areas. Better dissemination of information and technology for improved decision making regarding use of credit.
