آج کل دل جلوں میں رہتا ہوں
اپنے ہی دوستوں میں رہتا ہوں
لذتِ انتظار مجھ سے پوچھ
میں ترے راستوں میں رہتا ہوں
ساتھ رہتی ہے میرے تنہائی
گو کہ میں جمگھٹوں میں رہتا ہوں
کیا یہ کم میری تم سے نسبت ہے
میں تری نفرتوں میں رہتا ہوں
شہر کے شور سے ہوں تنگ آیا
جا کے پھر جنگلوں میں رہتا ہوں
میرا تائبؔ مزاج موزوں ہے
میں بڑے شاعروں میں رہتا ہوں
This study aims to compare the learning outcomes of physics taught using face-to-face learning models with online learning models at Islamic Senior High School 2 Palu City in the academic year of 2021/2022. In this study, the X1 variable consists of the face-to-face model, the X2 variable is the online learning model, and the Y variable consists of the results of learning Physics. This study used quantitative research with comparative analysis techniques. The subject of the research was students of X IPA 1 at Islamic Senior High School 2 Palu, which is totaling 25 students. Data collection was carried out using student learning outcomes tests, observation, and documentation. The method used for the analysis of hypothesis testing is the paired sample t-test. Descriptive, normality, and homogeneity tests were used for data analysis. The results showed that there were significant differences in the learning outcomes of Physics subjects between face-to-face learning and the online learning model for class X IPA1 Islamic Senior High School 2 Palu in the academic year of 2021/2022. The results of the descriptive analysis calculation show that there is a difference between the Physics Learning Outcomes Taught Using the Face-to-Face Learning Model and the Online Learning Model in class X IPA1 in the academic year 2021/2022. This shows that the face-to-face learning model is more effective than the online learning model in physics subjects.
Salinity is a serious concern for agriculture worldwide and it is increasing continuously. Drought-affected lands are severely affected by salinity, and crops production is drastically reduced. Soils of over 100 countries of America, Africa, Australia and Asia are facing serious salinity problem, mainly due to anthropogenic activities like irrigation. Now, salinity has also become a menance for agriculture in Pakistan because it is limiting the production of crops and affecting the country’s economy from nineteenth century. In Pakistan, approximately 6.67 million hactare area is facing the problem of salinity. In Pakistan, salinization is due to natural environmental conditions like ecological fluctuations, inefficient irrigation, high evapo-tanspiration, flooding, usage of low-quality water for irrigation and its poor drainage. This study was conducted to evaluate adaptive components of salt tolerance in Cyperus laevigatus L., which is a hydro-halophytic plant. Six populations of Cyperus laevigatus were collected from Sahianwala, Sargodha, Sangla Hill, Kalar Kahar, Pakka Anna and Domeli and their degree of salinity was assessed by examining their morpho-anatomical and physiological attributes. Cyperus laevigatus populations can be rated as Domeli ˂ Sargodha ˂ Kalar Kahar ˂ Sangla Hill ˂ Sahianwala ˂ Pakka Anna from least tolerant to the most tolerant, based on overall growth and biomass production under high salinities. The most tolerant population from the Pakka Anna relied on increased or maintained photosynthetic rate, high water use efficiency, restriction in Na+ uptake of in root and shoots, high uptake of shoot and root Ca2+ and K+, in addition to high accumulation of organic osmolytes, hence making this population more suitable for salt-affected areas. Structural adaptations like increased root area, thick root endodermal layer and large root metaxylem vessels, large stem area, broad metaxylem vessels, intensive sclerification in stem and leaf, increase in vascular bundle area and large cortical cells in stem, bract and leaves and decreased stomatal area and density all contributed significantly towards its high degree of salinity tolerance. Cyperus laevigatus can easily survive up to 600 mM salt, and differently adapted populations showed differential response towards salt stress tolerance and adopt different mechanisms based on morpho-physiology and anatomy. Therefore, this species can be effectively used to re-vegetate salt-affected areas, as well as for phytoremediation of salt affected lands.
