فرد قائم ربط ملت سے ہے تنہا کچھ نہیں

فرد قائم ربط ملت سے ہے تنہا کچھ نہیں
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز سامعین اور میرے ہم مکتب ساتھیو! آج مجھے جس موضوع پر لب کشائی کی سعادت حاصل ہورہی ہے وہ ہے:’’فرد قائم ربط ملت سے ہے تنہا کچھ نہیں ‘‘
صدرِذی وقار!
فرد ملت کی بنیادی اکائی ہے ،فرد ہے تو ملت ہے، فرد ہے تو قوم کا وجود ہے، فرد ہے تو اس کائنات کی رنگینیاں ہیں، فرد ہے تو اس کا ئنات کی رعنائیاں ہیں ، فرد ہے تواس گیتی کے گلشن میں بہار ہے، فرد ہے تو اس گلستانِ ہستی میں نکھارہے۔
جنابِ صدر!
یہ مصرع ہمیں اتحاد کا درس دے رہا ہے۔ہمیں اتحاد کی بابت آگاہ کر رہا ہے، فردکا وجود ہی اتحاد کی بدولت قائم ہے، اتحادکا لفظ ہے ہی بڑی جاذبیت کا حامل ، یہ جس فقرے میں آ جائے اس کے معنی میں حسن پیدا ہو جاتا ہے، چند اینٹیں متحد ہو جائیں تو مکان کی تعمیر ہو جاتی ہے، چند قطرے متحد ہو جائیں تو بحر بے کنار کی شکل اختیار کر لیتے ہیں۔
صدرِ ذی وقار!
اتحاد جس صورت میں بھی موجود ہو قابل تحسین تصور کیا جاتا ہے، جوقوم آپس میں مربوط ہوتی ہے وہ ہر لحاظ سے خوش و خرم ہوتی ہے، اس کی فضاؤں میں آلودگی کا زہر نہیں ہوتا، اس کے کھلیانوں میں غیر نافع بوٹیاں نہیں اگتیں، اس کے شجر سایہ دار خزاں آشنا نہیں ہوتے ، اس کے میدان ویران نہیں ہوتے ، اس کے ہسپتال آباد نہیں ہوتے۔
جنابِ صدر!
اسلام میں اتحادِ ملی پر بڑا زور دیا گیا ہے، حدیث پاک میں ہے کہ مسلمان مسلمان کا بھائی ہے، مسلمان مسلمان کوگالی نہیں دیتا، مسلمان مسلمان کو برا بھلا نہیں...

Advancing Age as a Risk Factor for Acute Myocardial Infarction

Background: Acute myocardial infarction (AMI) is one of the leading causes of death in developed and developing countries. Age is an important non-modifiable risk factor for acute myocardial infarction. Objectives: The objective of the study was to explore the relationship of advancing age with the risk of acute myocardial infarction. Methods: It was a cross-sectional study conducted in 2019 after getting approval from Institutional Review board of University of Health Sciences, Lahore. Written informed consent and thorough history was taken from the study participants. Group 1 included 45 AMI patients aged 20-60 years. Group 2 included 45 healthy individuals aged 20-60 years. Independent sample t test and chi-square tests were applied for analysis of data. Results: Mean age was significantly higher in AMI patients (50.52±7.31) as compared to healthy controls (30.67±7.20). The risk of AMI increases with advancing age (p<0.001, OR= 2.78). Conclusions: Advancing age is an important risk factor for acute myocardial infarction.

Analysis of Specific Cutting Energy Consumption During Machining of Al 6061-T6 Alloy, Using the Energy Map Approach

There is an increased emphasis on energy efficiency of manufacturing processes owing to their negative impact on environment. Machining is one of the most widely used process in the manufacturing industry and accounts for more than 15% value in the globally manufactured products. Electrical energy consumption is considered as the major source of environmental and economic impact of machining processes. A number of studies can be found in literature that model and optimize energy consumption in machining processes. However, most of these studies employ power and energy as response variables that makes them machine tool specific. Therefore a generalized machine tool independent approach needs to be developed for energy consumption analysis in machining processes. This research addresses this problem by utilizing specific cutting energy as a response variable. Specific cutting energy takes into account cutting power and material removal rate and is independent of machine tool. A novel specific cutting energy map approach has been presented in this research. Al 6061-T6 alloy has been used as the workpiece material owing to its extensive application in automotive, aerospace and other high-tech products. The developed energy maps can represent specific cutting energy consumption in the form of different regions (very high, high, moderate, low and very low) against varying cutting condition. The energy map approach has been applied in conventional, transitional and high speed machining ranges. The formation of specific cutting energy regions has been investigated and it has been shown that these regions are strongly related with mechanics of cutting process in terms of: shear angle, chip ratio, chip formation, and contact length. It has been shown that energy saving up to 52% in machining of Al 6061 alloy can be achieved by selecting appropriate cutting parameters from the developed energy maps. The undeformed chip thickness was observed to be the most influential machining parameter affecting specific cutting energy consumption. The developed energy maps also revealed the presence of an avoidance zone associated with high cutting speeds and low undeformed chip thickness. Built-up edge was observed to be responsible for formation of avoidance zone.
