قائد کا فرمان کام ، کام اور کام
نحمدہ وَ نُصَلِّیْ علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اساتذہ کرام اور میرے ہم مکتب ساتھیو!
آج مجھے جس موضوع پر اظہار خیال کرنا ہے وہ ہے:’’قائد کا فرمان کام، کام اور کام‘‘
جنابِ صدر!
اس کا ئناتِ رنگ و بو میں جو رنگینیاں نظر آرہی ہیں، اس کائنات میں جوحسن نظر آرہا ہے اس کائناتِ رنگ و بو میں جو تنوع دکھائی دے رہا ہے، اس کائنات کے گلشن میں جو بہار آ ئی ہوئی ہے، یہ سب کچھ اپنے آپ وجود میں نہیں آگیا، یہ کسی نہ کسی کاریگر کا شاہکار ہے، کسی نہ کسی محنتی کی محنت ہے۔
جنابِ صدر!
محنت اور جدوجہد ہی انسان کو انسانیت کے مقام پر فائز کرتی ہے، معاشرے میں اس کا ایک مقام بناتی ہے، کام سے محبت ہی بڑے بڑے کا م بناتی ہے، کام کرنے والا شخص کسی کا دست نگر نہیں ہوتا، اُس کی خودی میں اضافہ ہوتا ہے، اُس کی خودداری کی دیوار میں شگاف نہیں پڑتا، وہ غریب اور بے کس کی دستگیری بھی کر سکتا ہے۔
بے محنت پیہم کوئی جوہر نہیں کُھلتا
روشن شرر تیشہ سے ہے خانۂ فرہاد
صدرِذی وقار!
بانیٔ پاکستان قائدِ اعظم محمد علی جناح رحمۃ اللہ علیہ کا یہ فرمان زبان زدعام ہے کہ کام ، کام اور کام، اس نابغۂ روزگارہستی نے کام کر کے یہ ثابت کر دیا کہ اگر انسان کا ارادہ نیک ہو، انسان کے جذبات حق وصداقت کے ترجمان ہوں، اور مقصد نیک ہو، عوام النّاس کی خدمت کا جذبہ موجزن ہو تو مقصد کے حصول میں کوئی چیز رکاوٹ پیدا نہیں کرسکتی۔
صدرِذی وقار!

Background: Sleep is an essential function of our body. Many surveys have reported the prevalence of poor sleep in university students, especially in medical students. Objectives: The objective of the study was to evaluate the effect of physical activity and stress on sleep quality among medical students in Pakistan. Materials & Methods: An observational cross-sectional study was conducted on medical students of private medical colleges in Lahore. A convenient sampling technique was used and 210 students were selected. The Pittsburgh Sleep Quality Index (PSQI), Godin Shephard Leisure Time Physical Activity Questionnaire (GSLTPAQ), and Perceived Stress Scale (PSS 10) were used for data collection. We used SPSS version 20 to analyze data and applied statistical tests: Chi-square test and Logistic Regression. p-value < 0.05 was taken to establish significance. Results: Among the study participants 91(43.3%) were males and 119 (57.7%) were females. There was a significant effect of stress level on sleep quality (P=0.000*). The frequency of good sleepers was seen to increase by almost three times with increasing physical activity, however, this difference remained non-significant (p=0.07). The logistic regression test showed a significant relationship between poor sleep and stress (p=0. 008**) while no significant relationship was seen between sleep quality and physical activity. Conclusion: There was a significant association between poor sleep and high-stress levels and an increase in physical activity showed an increase in the frequency of good sleep, however, this difference was non-significant. It can be inferred that this positive effect of increasing physical activity on the quality of sleep could be indirectly due to its relieving effect on stress.
Potato processing industry is rising globally and increasing fast food demand of consumers exerts pressure on researchers to identify suitable potato cultivars for processing into chips and fries. Low sugar contents and light frying color are the principal traits to be observed for good chipping performance of potatoes. In potato industry, determination of sugar contents is particularly important as presence of high levels of sugars causes non enzymatic browning or Maillard reaction after frying of potato chips at high temperature. The current study was designed to screen out and assess the chipping potential of indigenous potato cultivars namely, Lady Rosetta, Santé. Hermes, Crozo, Kuroda and Asterix for sugar accumulation during storage at 3, 7 and 11ºC for 160 days (Phase I). The second phase was aimed to estimate the sugar reversion by applying reconditioning treatment at higher temperatures of 15, 20 and 25ºC for a short period of 30 days. All the physicochemical (specific gravity, dry matter, total starch ascorbic acid, sprouting, weight loss, hardness/firmness,) and biochemical analyses such as sugar contents (glucose, fructose, sucrose) and invertase enzyme activity were carried out at a regular interval of storage days. High Performance Liquid Chromatography (HPLC) was adopted for the quantification of sugars whereas the associated invertase activity appraised by spectrophotometrically. Considering the result of first phase; the correlation matrix for physicochemical and biochemical analyses revealed that specific gravity, dry matter content, percent weight loss and sprouting rate were positively correlated to sugar contents and invertase activity while negatively correlated to total starch, ascorbic acid and tuber’s hardness/firmness. Over the storage, gradual increase in sugar contents was observed during phase I, in which the maximum sugar accumulation was exhibited by tubers stored at 3ºC in contrast to 7 and 11ºC. Cold induced sweetening (CIS) under the influence of invertase activity was recorded highest in cultivar Kuroda, following the Santé, Asterix, Crozo, Hermes and Lady Rosetta. High temperature exposure to the stored tubers or reconditioning treatment for short time (Phase II) resulted in reversion of accumulated sugars to starch. The maximum reversion of sugars was attained at 20ºC as compared to 15 and 25ºC after 30th day of reconditioning. All the cultivars showed significant results for glucose, fructose and sucrose contents after reconditioning treatment such as Lady Rosetta (43.23, 38.33, 49.21 mg/100g), Hermes (48.97, 43.23, 39.23 mg/100g), Crozo (51.94, 46.72, 41.74 mg/100g), Santé (54.41, 51.37, 83.31mg/100g), Asterix (59.53, 62.11, 47.52 mg/100g) and Kuroda (86.93, 81.96, 51.21 mg/100g), respectively. The pattern of chips color was assessed and scored by using nine-point Hedonic scale after both phases. Consequently, significant variability (P < 0.05) in sugar contents and frying color was found among all cultivars, whereas Lady Rosetta with golden yellow chips color, Hermes having slightly yellow color and Crozo with yellow color were the most suitable cultivars for chips preparation after reconditioning. The outcomes of current study indicated that reconditioning at higher temperatures for short time resulted in a strong and diverse effect on starch sugar interconversion during storage. More importantly, these results proposed that reconditioning treatment of stored tubers could reduce CIS depending on the nature and type of the cultivar along with the applied storage conditions.
