بجلی کے بحران پہ کیسے قابو پایا جا سکتا ہے

بجلی کے بحران پر قابو کیسے پایا جاسکتا ہے
نہ چھوڑیں واپڈا والے اگر بجلی تو کیا غم ہے
’’یدِ بیضا لیے بیٹھے ہیں اپنی آستینوں میں‘‘
انسان گھر میں موجود ہے۔ گھر کا سارا نظام اس کی سر پرستی میں بحسن وخوبی رواں دواں ہے۔ دریں اثناء گھر کے آنگن میں خفتہ شیر خوار بچہ آواز کے ساتھ رورہا ہے اور اس کے رونے کی وجہ کوئی بیماری نہیں، کوئی اور خار جی عمل نہیں صرف اور صرف لوڈ شیڈنگ کے سبب شدت حرارت ہے جس نے معصوم کی نیند حرام کر دی ہے، اس کی اس بے چینی نے والدین کے قویٰ کومضمحل کر دیا ہے اور پورے گھر میں ایک بحران کی سی کیفیت ہوگئی ہے۔ اور اس قسم کے بحران صرف کسی خاص علاقے میں نہیں ہیں بلکہ ملک کی کثیر آبادی اس سے متاثر ہے۔
برقی رو کی کمی یا قلت سے ہر ایک متاثر ہوتا ہے۔ لائبریری میں کوئی پرسکون فضاء میں محو مطالعہ کتب ہو، یا ظرف ہائے طعام اُٹھائے موجود غلام گردش ہو، کوئی کوچہ بازار میں موجود ہو، یا کوئی گھر کی بالکونی میں قیام پذیر ہو، کوئی صنعتکاری کے میدان سے مربوط ہو، یا کوئی زراعت و کاشتکاری کے میدان سے وابستہ سب کے سب بجلی سے نبردآزما ہیں۔
اس بحران پر قابو پانے کے لیے اقلیم عقل و خرد کی فرمانروائی کے ساتھ نصرت الٰہی کا طلبگار ہونا ہو گا۔ اس مہیب سائے کواجالے میں بدلنے کے لیے ابتدائی طور پر کاشانۂ خویش کو سامنے رکھنا ہو گا۔ اصراف وتبذیر جیسی خصائل قبیحہ سے کنار کشی اختیار کرنی ہوگی ،کفایت شعاری جیسی خصلت صالحہ کو اوڑھنا بچھونا ہوگا۔ اگر ایک شخص فضول خرچی جیسی لعنت سے چھٹکارا حاصل نہ کرے اور دن رات اسی عادت سے وابستہ رہے تووہ بھی اپنے مقصد میں کامیاب نہیں ہو...

ACADEMIC MOTIVATION LEVEL AND ATTITUDE TOWARDS SOCIAL STUDIES AMONG PUBLIC SCHOOL SECONDARY STUDENTS IN ZAMBOANGA SIBUGAY PHILIPPINES

In a Social Studies, students' academic motivation and attitudes will be useful to their academic progress. If a student is enthusiastic about a subject, he or she will do better in class and learn faster. There have been a lot of studies that have looked into students' academic motivation and attitudes toward social studies, but there does not appear to be any study that focuses on the learners themselves. This quantitative study aims to determine the level of academic motivation as well as the attitude toward social studies of 458 secondary students from public schools using the Academic Motivation Scale High School Version and Secondary Students Attitudes Towards Social Studies Scale. It also looked at whether there was a significant difference in academic motivation and attitude toward social studies when respondents were sorted by gender. Finally, it investigates the link between academic motivation and attitude towards social studies. Students are found to be "highly motivated" in terms of academic motivation and have a “positive attitude” toward social studies, according to the findings. Furthermore, when respondents were divided into gender groups, no significant differences in academic motivation and attitude toward social studies were found. Finally, academic motivation and attitude toward social studies show a significant favorable relationship.

Evaluation of Some Commercial and Candidate Cultivars of Spring Wheat Triticum Aestivum L. for Salt Tolerance

A study was planned to assess the salt tolerance potential of 10 wheat cultivars, five newly developed (S-24, Saher-2006, Inqlab-91, Faisalabad-2008 and Lasani) and five candidate (P.B-18, M.P-65, SH-20, AARI-10, G.A-20). Two salinity levels were (0 mM and 150 mM) applied at three growth stages seedling, tillering and boot stages. This study comprised independent two experiments. The first experiment was performed to screen the 10 wheat cultivars on the basis of biomass production and yield under saline stress. Four wheat cultivars (S-24, Saher-2006, Lasani and AARI-10) were selected on the basis of the results of the first experiment and again grown in the following year for detailed study of physio-biochemical responses under saline stress imposed at different growth stages. Saline stress application at different growth phases caused a marked reduction in biomass production, yield, different gas exchange attributes, photosynthetic pigments and water relation parameters. However, comparatively cvs. S-24 and Saher-2006 showed less reduction in these attributes due to saline application at three growth stages. Less cholophyll degradation, comparatively higher photosynthetic and transpiration rate and leaf turgor were observed due to saline stress imposition at the boot stage. However, it was greater due to salinity imposed at the seedling stage. Furthermore, NaCl applied at three different growth stages markedly increased the endogenous Na+ level and caused reduction in Ca2+, K+, K+/ Na+ and Ca2+/ Na+ ratios. Overall, cvs. Saher-2006 and S-24 maintained higher K+/ Na+ and Ca2+/ Na+ ratios as compared to the other wheat cultivars under salt stress. There was a less decrease in K+/ Na+ and Ca2+/ Na+ ratios under the saline environment developed at the boot stage while maximum at the seedling stage. A significant alteration in different biochemical attributes was observed in all wheat cultivars under saline stress imposed at three growth stages. For example, a substantial increase was observed in H2O2, MDA, soluble proteins, proline, glycinebetaine and activities of different aintioxidants (SOD, POD, CAT, phenolics). Different wheat cultivars showed variation in these biochemicals in response to salt stress applied at different growth stages. Maximum antioxidative enzymes activities were observed in cvs. S-24 and Saher-2006 due to saline stress application at three growth stages. However, cvs, S-24 and Sher-2006 had higher accumulation of GB and proline as compared to the other cultivars (Lasani and AARI-10) under saline stress imposed at early growth stages (seedling and tillering) than at the boot stage. Anatomical studies of four wheat cultivars under saline stress applied at different growth stages showed that cvs. S-24 and Saher- 2006 had thick epidermis of stem and root, greater schlerification in stem and leaf, higher vascular bundle and metaxylem area and greater cortical cell area due to saline stress applied at three different growth stages than the other two cultivars (Lasani and AARI- 10). These anatomical characteristics showed their better adaptability under saline environment in terms of checking water loss, good water storage capacity, and better toxic ion compartmentalization due to large size vacuoles of cortical cells and better water and nutrient transport through vessels. So, it can be inferred that wheat is more prone to adverse effects of saline stress when applied at the early growth stage (seedling) than at later growth stages. Overall, of all wheat cultivars cvs. S-24 and Saher-2006 were more tolerant to saline stress.
