The present project was designed to probe the effect of diversified modification methods on the functional, structural and nutritional attributes of cereal starches. Purposely, starch was extracted from rice and corn grains and modified by Heat Moisture Treatment (HMT), acid hydrolysis, oxidation, cross linking and Octenyl Succinic Anhydride (OSA) modification methods. The compositional analysis of corn and rice revealed 69.84±3.22 % and 79.12±2.86 % starch. The morphological examination depicted regular, polygonal small granules of starch by Scanning Electron Microscopy (SEM). The pasting properties of all the modified corn and rice starches exhibited significant differences. The solubility of modified starches varied from 5.43±0.17 % to 17.27±0.52 % while the light transmittance was highest in oxidized (46.13±2.15 %) trailed by OSA (43.40±2.18 %), acid hydrolysis (26.93±0.95 %), native (23.77±1.16 %), HMT (16.30±0.87 %) and cross link (13.37±0.45 %) in modified rice starches. Similar trend was observed regarding the solubility and light transmittance values of modified corn starches. The modification process reduced syneresis as a function of storage in both rice and corn modified starches with lowest synersis value in OSA modified starches. The structural properties of modified starches were exemplified by SEM and X-ray diffraction (XRD) studies. The photomicrographs revealed that HMT produced slight agglomeration along with granular disruption, acid hydrolysis did not cause any pronounced effect on granule morphology while rough edges and cluster formation occurred in starch granules after cross linking and OSA modification in both the rice and corn starches. The polymorphic forms as examined by XRD depicted that rice starches elucidated A-type crystalline pattern with characteristics peaks at 15.92, 17.24, 17.78 and 22.94º (2θ). All the modified starches exhibited the same pattern and no noticeable changes in rice starch were observed after various modification processes. Likewise, corn starches also illuminated similar A-type crystalline pattern with sharp peaks at 15.92, 17.21, 17.73 and 22.91º (2θ). The diffractrogram explicated that the process of modification occurred in the amorphous zone of starch granules. Furthermore, the modified starches were examined for the nutritionally beneficial component of starch i.e. resistant starch (RS). The resistant starch content of modified rice starches expounded that RS increased from 6.57±0.28 % to 26.75±1.69 %. Likewise, RS content in modified corn starch also boosted from 13.67±0.87 % to 41.76±2.15 %. Furthermore, modified starches were incorporated in wheat flour and their effect on dough and bread quality was assessed. The addition of modified starches significantly affected the rheological properties of wheat flour as determined by farinograph and RVA. Bread prepared by the addition of modified starches especially OSA rice starch revealed significant improvement in texture during storage. The hypocholesterolimic potential of modified starches was demonstrated through bio-assay trial and the provision of modified corn starch supplemented diet caused significant decrease as compared to modified rice starch in serum cholesterol, LDL and triglycerides as 5.07 % , 9.03 % and 6.09 %, correspondingly. Conclusively, modifications of cereal starches noticeably affected their functional properties and enhanced their utilization under rigorous processing conditions. Addition of modified starches in bread showcased their anti staling properties and the bio-assay trial illustrated the prophylactic potential to lower hyperlipidemia.
انگریز راج سے پہلے پنجاب سکھو ں کی سلطنت کے تحت تھا۔مسلمان ایک قیدی جیسی زندگی گزار رہے تھے نہ وہ اذان دے سکتے تھے، گائے ذبح کیے جانے تک پر موت کی سزا کا حکم جاری ہوتا تھا۔جنگ کے دوران سکھ خود کو بچانے کیلییمسلمان خواتین کو گھرو ں سے نکال لاتے اور ٹینکوں کے اردگرد باندھ دیتے تاکہ مسلمان حملہ نہ کرپائے۔یہ تھی جنگ کے دوران بربریت کی حالت سکھ قوم جب بھی تشدد کرتی تو زیادہ تر مسلمانوں کو ہی اپنے تشدد کا نشانہ بناتی لوٹ مار کرتے ہوئے بے تکلفی سے کام لیتی۔مسلمانوں کے بڑے مقبروں سے بھی سکھ قوم نے پتھر اکھیڑ دیے۔ان حالات کو دیکھتے ہوئے مسلمان قوم اس حکومت کے ختم ہونے پر شکر ہی کرسکتی تھی۔ ہمارے ملک نے الگ پہچان پانے کیلئے نہ جانے کتنی سختیاں برداشت کی ہیں، آج کا انسان اس بات کا اندازہ لگا ہی نہیں سکتا۔
تقسیم ہند کے کچھ واقعات ایسے ہیں کہ جن کو سن کر پڑھ کر دل خون کے آنسو روتا ہے ، روح کانپ جاتی ہے۔یہ ہم ہیں جو سنتے ہیں ،صرف محسوس کرتے ہیں تو روح کانپ جاتی ہے تو وہ لوگ جنہوں نے اس کو جھیلا ہے، ان کو سوچ کر آنکھیں اشکبار ہوجاتی ہیں۔تقسیم پاک وہند میں اپنی جانیں،عزتیں ،مال ودولت سب کچھ قربان کردیا صرف اپنے اس پاک وطن کی خاطر۔وہ دن جب اس خوشی کااعلان کیا گیا تو ہر طرف ہنگامہ ہو گیا۔خوشی تھی کہ قیام پاکستان کا اعلان کیا گیا وہ مبارک 27 رمضان المبارک کی کڑی صبح اپنے ساتھ ساتھ غم کا پیغام بھی لائی کہ ہمارے مسلم بے یارو مددگار کہیں مردہ تو کہیں زندہ پڑے نظر آئے۔یہ ایک کڑا امتحان تھا ہمارے لیے...
The present paper explores and introduces a manuscript on i‘jaz al-Qur’ān (inimitability of the Qur’ān) named Nūr al- Īqān bi i‘jaz al-Qur’ān written by a profound South Asian Sindhi Scholar, Maulana Muhammad Ismā‘īl al-Ūdvī. The field of i‘jaz al-Qur’ān has been and is the field of interest of many Muslim as well as non-Muslim theologians and scholars. Many Muslim scholars of the Middle East and the West have written books and research papers from third/ninth Century up to present times. The main and significant reason for this is that the doctrine of i‘jaz al- Qur’ān proves the prophecy of Prophet Muhammad peace be upon him. This paper argues that Shaikh al-Ūdvī is the first South Asian Sindhi Muslim Scholar, who wrote a separate treatise in Arabic on the doctrine of i‘jaz al-Qur’ān, which is not introduced properly in academic circles of the day. In this treatise, al-Ūdvī has advanced some new and original arguments to support the doctrine and the prophecy of Prophet Muhammad peace be upon him.
The Medium Term Development Frame Work (MTDF) 2005-10 by Planning Commission Government of Pakistan states the policy for power sector in which it puts a greater emphasis on nuclear power resources by increasing its share from currently 425 MW to 8800MW by 2030. With the increase of nuclear share in the overall national energy mix, a corresponding environmental impact and nuclear safety analysis are equally important. These are usually taken care of by Primary Safety Analysis Report (PSAR) of a proposed nuclear power plant. The PSAR of any proposed nuclear power plant involves the assessment of a hypothetical accidental release of radionuclides in the atmosphere as set forth by US-NRC and PNRA such as those given as criteria for preparation and evaluation of radiological emergency plans and preparedness (10CFR100, PAK/910). Modeling atmospheric dispersion (both transport and diffusion) is the first step of such assessments. The objective of this work is to determine a more precise modeling methodology that can better predict the radiological consequences in terms of radionuclide concentration and doses compared to Gaussian dispersion approach that is based on assumptions such as uniform turbulence, flat topography and non-variant wind speed with time and space. The research goal was achieved by developing two broad strategies on the basis of Lagrangian approach. The first strategy is an effort to provide a simple answer to the complex problem. This methodology makes use of empirical parameterization of meteorology which serves as input for dispersion calculations by Lagrangian Stochastic Particle Model (LSPM). But the beauty of approach is its capability to capture complex atmospheric phenomenon like wind directional shear. This approach was used to study hypothetical accidental release of radionuclides in nocturnal atmosphere which generates maximum wind directional shear. The results of dispersion in terms of dispersion coefficients were in good comparison with that of experimental findings in the available literature. The resulting ground level concentrations of radio-nuclides and radiological dose contours were also compared with those based on approach analogous to Gaussian Plume Model (GPM). The exercise proved that how misleading results would be if we ignore wind directional shear in stable atmosphere. The second approach is based on a state of the art solution. It involves the coupling of an Eulerian meteorological model (RAMS) with LSPM. The meteorological model is responsible to provide meteorological input to LSPM at each grid point and at each time step. This computational technique was used to simulate a hypothetical accident at a proposed site for Nuclear Power Plant. The meteorological output of the modeling system was compared with observed values. The comparison proved the efficacy and reliance of the approach. This computationally intensive but effective strategy is quite capable of supporting a real time decision making system for tackling nuclear emergency.
