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.
اک دفعہ دا ذکر اے کہ کسے پنڈ وچ کسے بندے نے بہت وڈے رقبے وچ تربوز کاشت کیتے ہوئے سن۔ تربوز نوں منڈی تک لے جاون لئی اوہنے اک اونٹ وچ رکھیا ہویا سی۔ اوہ تربوز دی گڈ بھر دے تے اونٹ اوس گڈ نوں کھچ کے منڈی لے جاندا۔ اونٹ بڑا موٹا تازہ سی تے مالکاں اوس دا ناں بلو رکھیا ہویا سی۔ مالکاں نے اپنے اونٹ دی دیکھ بھال لئی اک نوکر رکھیا ہویا سی جو بہت بیوقوف سی۔ کئی وار اوہ اونٹ نوں پٹھے پانا بھل جاندا۔ کئی وار اونٹ نوں پانی پلانا تے چھاویں بنھنا بھل جاندا۔ اوس دے مالک اوس دی ایس عادت توں بہت تنگ سی۔
اک دن نوکر اونٹ نوں اکلا چھڈ کے کتے باہر کم چلا گیا۔ اونٹ تربوز دے کھیتاں اندر وڑ گیا تے تربوز کھانے تے خراب کرنے شروع کر دتے۔ اچانک اک تربوز اونٹ دے گلے وچ پھس گیا۔ جدوں مالک نے ویکھیا تاں بہت پریشان ہویا۔ فیر اوس اک چادر لئی تے اوس نوں اونٹ دی گردن دوالے لوپٹ دتا۔ ایس توں بعد اک ڈنڈا پھڑ کے اونٹ دی گردن اتے زور نال ماریا۔ جس پاروں اونٹ دے گلے وچ پھسیا تربوز ٹٹ گیا۔ اونٹ نے کجھ تربوز نگل لیا تے کجھ منہ توں باہر کڈھ دتا۔ انج اونٹ دا ساہ سوکھا ہویا۔ اوہ بیوقوف بندہ ایہہ سارا کجھ ویکھ رہیا سی۔ مالک نے اوہنوں نوکری توں جواب دے دتا تے اوہ اپنا سامان چک کے نال والے پنڈ اپڑ گیا۔
پنڈ پہنچ کے اوس نوں کئی گلہڑ دے مریض نظر آئے۔ اوس نے اپنے آپ نوں حکیم دسیا تے گلہڑ دا علاج کرن دا دسیا۔ پہلاں پنڈ والیاں اوس اتے اعتبار نہ کیتا۔ فیر کجھ دناں اوہناں نوں یقین ہو گیا کہ...
The development of Islamic boarding schools is one of the targets for sharia economic development which is based on the understanding of the halal value chain where the development of Islamic economics and finance summarizes various initiative programs including the development of Islamic boarding schools. The purpose of this study is to describe how the implementation of the Islamic Boarding School Accounting Guidelines at Al Huda Islamic Boarding School which is more focused on the readiness of HR at Al Huda Islamic Boarding School in applying the Islamic Boarding School Accounting Guidelines. The Al Huda Islamic boarding school was chosen as the research locus because the Al Huda Islamic Boarding School was appointed by Bank Indonesia Gorontalo Representative Office as a pilot project for the Pesantren (Islamic Boarding School) which applies the Islamic Boarding School Accounting Guidelines. The stages of the research method began with observations and results of interviews with informants from the board of the Al-Huda Islamic Boarding School. The results showed that there was a desire to apply these guidelines in the Al-Huda Islamic boarding school. Even though treasurers, secretaries and operators do not have a basic knowledge of the Economics of Accounting, the existing human resources are ready to apply the Pesantren accounting guidelines, of course, adjusting to the needs of the Al-Huda Islamic boarding school. The author sees that there is no urgency in implementing Islamic boarding school accounting guidelines at the Al-Huda Islamic boarding school because the reporting entity is the foundation that houses the Al-Huda Islamic boarding school, the Al Huda Islamic Education and Da'wah Foundation, Gorontalo. The foundation is fully responsible for the donors or the community.
The purpose of my study was to implement mathematical tasks based on the learning theory Constructivism and to explore the difficulties of class five students, and my own difficulties as a teacher when using this learning theory. For this purpose, I designed tasks on the basis of my assessment of students' needs and their prior knowledge about the particular mathematical topic being taught. I myself taught class five and personally developed lessons based on constructivism. Therefore, my teaching and interviews allowed me to have a close association with my sample of four students and to get a deeper understanding of the students as well as my own difficulties. In order to gain in-depth information regarding students' difficulties in learning mathematical concepts, I interviewed the students using open-ended questions. The questions were designed on the basis of students' difficulties identified through my reflections and through discussions with my supervisor. The analysis of students' documents (homework and classwork) and interviews with the mathematics teacher, who observed my teaching, provided me with the necessary data required to answer my research questions. The major findings regarding the nature of the tasks which provided the best learning opportunities to the students included: use of concrete materials, problem solving/individual work, presentation of students' work, and a friendly atmosphere in the class. Students' difficulties included problems in representing their derived formulas in symbolic form, calculating the area of a rectangle and triangle was challenging for the students when measurements of length and breadth were two digit numbers, misinterpreting local language created difficulties in understanding mathematical concepts like length, breadth and height. The difficulties I felt as a teacher included selecting appropriate words for proper instructions according to the students level of understanding, maintaining discipline in a class of 40 students, using appropriate resources and so on. Conclusions made on the basis of my findings are as follows. Lack of students prior knowledge is a strong obstacle for students when they are involved in construction of further knowledge by themselves. A friendly but well disciplined class plays a key role in developing students' interest, curiosity and enthusiasm in learning. Unfavourable physical conditions hinder students' involvement in their construction of knowledge. Teacher's lack of skill in giving appropriate instructions and selection of resources becomes a strong obstacle in students construction of their own knowledge.
