بیماری سے بچاؤ کے لیے ریاست اور عوام کا کردار
بیماری ، عارضہ، مرض اور روگ یہ ہم معنی الفاظ ہیں۔ مرض اور بیماری صحت اور تندرستی کا متضاد ہے، انسانی اعضاء جب تک اپنے افعال کماحقہٗ سر انجام دیتے رہتے ہیں صحت و تندرستی برقرار رہتی ہے۔ اگر ان کے افعال کی بجا آوری میں رخنہ پیدا ہو جائے تو یہ مرض اور بیماری ہے۔ اس کا سبب خواہ خارجی عوامل ہوں یا اندرونی طور پر کوئی غیر مرئی طاقت برسر پیکار ہو! تندرستی اور صحت قدرت کی طرف سے ایک عظیم عطیہ ہے۔ اس نعمت خداوندی کے زیور سے مرصعّ انسان دیگر انعامات الٰہیہ سے بھر پور فائدہ اٹھایا جا سکتا ہے۔ لیکن اگر کسی کے آنگن میں گلشنِ صحت کے گلہائے رنگارنگ نہیں کھلے۔ بیماری اور مرض کے مہیب ومنحوس سایوں نے اسے اپنی لپیٹ میں لے رکھا ہے۔ بستر مرگ پر پڑا ہوا وہ نحیف شخص اپنی نقاہت بھری نظروں سے گلستان صحت و تندرستی میں محو پرواز طائران خوش الحان کو حسرت بھری نگاہ سے دیکھ تورہا ہے لیکن وہ کائنات کی رنگینیوں اور رعنائیوں سے بھی حظّ نہیں اُٹھاسکتا۔
تنگدستی اگر نہ ہو سالکؔ
Principal leadership activities in utilizing social media can affect the effectiveness of organizing, coaching, and communication. This study discusses effective communication with students through utilizing social media. Communication through social media is done by forming groups in various social media. This research was conducted with a survey method that uses data analysis with path analysis methods where calculations are performed with the program used are Data Analysis packages found in Microsoft Excel and SPSS. The subjects of this study were the deputy principals of the Vocational High School students' field of 100 people in the city of Bekasi. The determination of the sample was taken using Slovin formula and random sampling technique, as many as 80 deputy principals in the student field were the sample of the study while 20 deputy principals in the student field were used to test the validation of the research instruments. This research is expected to contribute to society.
Three independent experiments were carried out in hydroponic and sand cultures to explore the alleviating effects of different levels of silicon (Si) on growth related attributes and some vital physio-chemical characteristics in two maize cultivars exposed to NaCl-induced salinity stress. Each experiment comprised two maize cultivars (Sadaf and Sahiwal-2002), two salt concentrations (0 and 120 mM NaCl) with varied Si concentrations. Initially, nine Si levels (0, 0.4, 0.8, 1.2, 1.6, 2.0, 2.4, 2.8 and 3.2 mM) were used for optimization of Si levels in Hoagland’s nutrient solution. Silicic acid [Si(OH) 4 ] was used as a source of Si. Four Si levels (0, 1, 2 and 4 mM) were selected from the optimization experiment, which then were employed for major experimentation. Interactive effect of Si and salt on growth, gas exchange characteristics, plant pigments, chlorophyll fluorescence attributes, biochemical parameters like proline, total phenolics, H 2 O 2 , MDA, antioxidant enzymes (CAT, POD and SOD) and ion accumulation (Na + , Ca 2+ , K + , Cl - and Si) were determined. Exogenous application of Si improved the growth, photosynthetic efficiency, membrane stability, and antioxidant activities and alleviated the toxic effect of Na + ion via improving plant K + , water status, photosynthetic efficiency, membrane stability and activities of antioxidant enzymes. Of various levels, 1 or 2 mM Si were found more effective in this regard under control conditions. However, under stressful environment, 4 mM of Si gave maximum protection against salt stress. Of yield attributes, a positive association was found between Si application and grain yield per plant, although, Si made no change in 100-grain weight. Conclusively, Si had a positive impact on overall health of plant especially under stressed environment and was found effective in the enhancement of salinity tolerance of maize plants.
