بابِ تاثیر سے انجیلِ کربلا تک
کائنات میں موسموں کی موجودگی سے طرز تکلم کے درجاتی دائروں کی دنیا ہو یا جذباتی سولات سے یقین کے منظروں میں شرطوں کی بحث ،یہ کبھی بھی لذتِ تاثیر سے خالی نہیں ہوتی ۔اس میں آرادھنا ،سادھنا کے معنوی تجربات بھی شامل ہو کر ،فکر کے داخلی رجحان کے ساتھ پھولوں کے رنگوں کی گرہ کھولتے ہیں ۔یہ جواز احساس کی خارجی خصوصیات کو جب آرادھنا کے سبز پتوں میں لپیٹ کر الہامیہ نفسیات کے زاویوں میں سمو کر ،ماضی کے تخلیقی اور موجودہ دور کے تحقیقی دروازے کھولتے ہیں تو سوچوں کے رویوں پر اثر انداز نہیں ہوتے کیونکہ لذتِ تاثیر اور تحقیق’’اپنے عہد کی زندگی کا سامنا کرنے اور اسے تمام امکانات و خطرات کے ساتھ برتنے کا ہنر سکھاتی ہے ۔جسے جدت کے نام سے بھی پہچانا جاتا ہے ۔ہر عہد میں جدیدت ہم عصر زندگی کو سمجھنے اور برتنے کے مسلسل عمل سے عبارت ہوتی ہے ۔اس لحاظ سے جدیدیت ایک مستقل عمل ہے ۔جو ہمیشہ جاری رہتا ہے ۔‘‘(جدیدت اور ادب ،وحید اختر)
ادبی کائنات میں جو تحیر اور طلسم سے سلسلہ شروع ہوتا ہے وہ آرادھنا ،سادھنا کے ساتھ مناجاتوں تک چلا آتا ہے ۔پھر کیفیاتی اسرار شروع ہوتے ہیں ۔جن کی وجہ سے عکس فسوں اسرار آگہی کی کرنوں میں ڈوبے سبز پتوں کا صحیفہ کھلنے لگتا ہے ۔جس کی وجہ سے فکری سوچ کی وادیوں میں نفسیاتی مقامِ مقدسہ نظر آنے لگتے ہیں ۔کبھی خود سپردگی کی ہئیت تو کہیں اسیر خواب و من الشباب کی جلی، خفی جذبات کی بارشوں میں بھیگی صورتیں نظر آنے لگتی ہیں ۔
اس سارے منظر نامے میں بکھری اساطیری رمزوں اور جدید اشاروں کو علمی دائروں میں پرکھنے کے ساتھ...
Constructivism is the basis for thinking of a contextual approach, namely that knowledge is built not a set of facts, concepts, or rules that are ready to be remembered. Students must construct that knowledge and give meaning through real experience. Students need to be accustomed to solving problems, finding something useful for themselves, and struggling with ideas. The teacher will not be able to give all knowledge to students. Students must construct knowledge in their own minds. Knowledge is not static, but is constantly evolving and changing as students construct new experiences that force them to base themselves and modify previous knowledge. Learning must be packaged into the process of constructing knowledge rather than receiving knowledge. In the learning process, students build their own knowledge through active involvement in the learning and teaching process. Students become the center of activities, not teachers. Critical thinking is an attempt by someone to check the truth of information using the availability of evidence, logic, and awareness of bias. Critical thinking skills are the cognitive processes of students in analyzing systematically and specifically the problems faced, distinguishing these problems carefully and thoroughly, as well as identifying and reviewing information to plan problem solving strategies.
Consequences of discontinuous chicken frying on some important parameters of soybean (SBO), sunflower (SFO) and canola oil (CLO) at constant temperature of 190 o C for 12 h were examined. The quality parameters such as fatty acid composition (FAC) with special emphasis on trans fatty acids (TFAs), free fatty acids (FFAs), iodine value (IV) and peroxide value (PV) of SBO, SFO and CLO were evaluated by taking out the oil samples from the fryer at an interval of 2 h. The total TFAs increased during frying of chicken in the range of 0.77- 1.67, 1.02- 2.62 and 1.29-3.14% in SFO, SBO and CLO. Other chemical parameters such as FFAs was 0.03-0.78, 0.05-0.49 and 0.19- 1.47%, PV was 1.51-3.04, 2.11-6.07 and 2.90- 8.02 meqO 2 /kg of oil increased whereas IV at 154.21- 140.69, 134.50 and 116.10-99.70 g/100g was decreased with respect to time of frying in SFO, SBO and CLO, respectively. The effect of commercial fish frying on the stability of FOs was examined at different intervals of time. The FO samples were collected into two phases; one before frying (unused) and other after frying (used; null replenishment, discarded). The main indicators of FOs determined during frying procedure were FAC, TFAs, FFA and PV. The FAC and TFAs in the FO samples were analyzed using the GC-MS. The TFAs were present in the range of 2.5-3.8, 5.6-14.8 and 7.3-20.8% in the fresh, null replenishment and discarded FO samples, respectively during the different frying periods. FFAs in fresh, NR, and discarded oils were 0.12%–0.24%, 0.22%–1.74%, and 0.80%–3.39%, respectively. PV in fresh, NR, and discarded oils were determined to be 1.15–3.93, 2.71– 7.51, and 2.84–14.68 meqO 2 /kg of oil. It was observed that commercial fryers were notusing the proper oil for frying. Furthermore, the last frying cycle just before discarding the oil may be dangerous for the health of consumers due to their significant level of TFAs, FFAs and PV. An easy UV spectrometric methodology was developed to assay PV of the FO samples. The assay of PV was based on the stoichiometric reaction of triphenylphosphine (TPP) with hydroperoxides available in FO samples to yield oxide of TPP, which indicates a reasonable absorption at 240 nm in UV region. The level of PV was found in the range 0.15-11.66 meqO 2 /Kg of oil in heated CLO samples for 1-12 h at frying temperature (180 0 C). Present methodology was compared with official procedure. The correlation of coefficient (R 2 ) was observed as 0.99525 which found in good agreement with official procedure. The present methodology may be used as a disjunctive to the official procedure, for the analysis of PV in FO samples. In another study the changes in main fat groups like saturated, monoene, trans and polyunsaturated FAs and their key fatty acid ratios (SFA/UFA, cis PUFA/SFA, C18:2/C16:0 and C18:3/C16:0) were investigated during potato chips frying in CLO. Single bounce attenuated total reflectance Fourier transform infrared (SB-ATR-FT-IR) spectroscopy was used for rapid analysis. The data obtained from gas chromatography- flame ionization detector (GC-FID) used as reference. The calibration of main fat groups and their key fatty acid ratios were developed by partial least square (PLS) regression coefficients using 4000 to 650 cm -1 spectral range. FT-IR PLS regression for the predicted SFAs, MUFAs, TFAs and PUFAs were found 0.999, 0.998, 0.998 and 0.999, respectively. Whereas for SFA/UFA, cis PUFA/SFA, C18:2/C16:0 and C18:3/C16:0 the regression coefficients were 0.991, 0.997, 0.996 and 0.994, respectively. We concludedthat FT-IR-PLS could be used for rapid and accurate assessment of changes in the main fat groups and their key fatty acid ratios ratio during frying process. The quantity of total polar compounds (TPC), carbonyl value (CV), conjugated diene (CD) and conjugated triene (CT) were monitored during potato chips frying in canola oil. Transmission Fourier transform infrared (FT-IR) spectroscopy was applied to attain improved sensitivity using 100 μm KCl cell. Partial least square (PLS) regression was applied to assess spectral regions correlating with known value of TPC, CV, CD and CT. Excellent coefficient of determinations were obtained as 0.997, 0.997, 0.999 and 0.999 for TPC, CV, CD and CT, respectively. The calibration models obtained were applied to analyze samples of canola oil drawn during potato chips frying from 1 to 7 h with wide ranges of 1.33 to 19.55% for TPC, 7.12 to 31.06 μmol/g for CV, 3.17 to 26.96 mmol/l for CD and 0.01 to 6.67 mmol/l for CT. A linear relationship was obtained between CD and TPC with a good correlation of coefficient (R 2 = 0.936). Results were compared with values obtained by their standard methods and found to be comparable. Outcomes of the present study revealed that transmission FTIR-PLS method could be used for quick and precise evaluation of oxidative changes occurred during frying process without using any organic solvent.
