Salinity is a major environmental stress which is reducing crop yields as well as tree growth particularly in arid and semi-arid zones. In Pakistan, large cultivated land is affected by various degrees of soil salinity and sodicity. There exists a great diversity among plant species for their salt tolerance. Screening of plant species for salt-affected soils is based on their survival and relative growth on higher salinity levels. Keeping these facts in view, three studies were planned to explore the salinity tolerance and response on water stress of two different conocarpus species viz Conocarpus lancifolius and Conocarpus erectus. In the first experiment, four month old seedlings of both species were transplanted in half strength Hoagland nutrient solution having ,five treatments (control, 100, 200, 300 and 400 mMNaCl). The data regarding growth and ionic composition (Na+ and K+) showed that Conocarpus lancifolius was more tolerant to salinity than Conocarpus erectus. The seedlings of Conocarpus erectus and Conocarpus lancifolius survived at 400 mMNaCl and decreased in plant height and fresh weight due to higher salt concentration were 62%, 67% and 68%, 73%, respectively. Both the species were further studied under the combination of salinity and water stress in the pots at half and double field capacity, where Conocarpus lancifolius proved to be better tolerant to salinity and water stress. In the final study these species were grown in the salt affected field and their annual growth and ionic data were recorded for two years. The changes in the soil chemical and physical properties were also determined at these intervals. The comparison of both species indicated that Conocarpus lancifolius produced more biomass and caused marked reduction in the soil chemical properties like pHs, ECe and SAR as compared to Conocarpus erectus, due to more addition of organic matter and rhizosphere acidification .On the other hand the physical properties like bulk density and infiltration rate were also improved more under Conocarpus lancifolius than under Conocarpus erectus. Results revealed that conocarpus species will prove to be a good source of timber, fuel wood and forage for livestock as well as rehabilitating barren lands.

آہ ڈاکٹر فریدی
جس حادثہ کا دھڑکا عرصہ سے لگا ہوا تھا وہ بالآخر پیش آکر رہا اور جس کے ہاتھوں سے اﷲ تعالیٰ نے ہزاروں مایوس مریضوں کو شفا بخشی تھی۔ اس نے بھی گزشتہ ۱۹؍ مئی کو جان جاں آفریں کے سپرد کردی، مرحوم فریدی کے کن کن اوصاف کو یاد کیا جائے۔
اے تو مجموعۂ خوبی بچہ نامت خوانم
وہ ایک حاذق طبیب، بے غرض مخلص اور جری لیڈر اور سراپا انسانیت اور شرافت تھے، قومی و ملی مفاد کے مقابلہ میں کسی طاقت کو خاطر میں نہ لاتے تھے، اس کے لئے آخر وقت تک حکومت سے جنگ کرتے رہے، اور اپنی دولت، صحت اور زندگی کسی چیز کی بھی پروا نہ کی اور ایک بہادر سپاہی کی طرح اس راہ میں جان تک دے دی، انھوں نے قوم و ملت کے لئے جو قربانیاں کیں اس دور کے مسلمانوں میں مشکل سے اس کی مثال مل سکتی ہے، ان کا سب سے بڑا کارنامہ یہ ہے کہ انھوں نے مسلمانوں سے خوف و ہراس اور احساس کمتری دور کرکے ان میں جرات و ہمت پیدا کی، ان کا دامن فرقہ پروری سے بالکل پاک تھا، انھوں نے اقلیتوں اور پسماندہ طبقوں کے مفاد کے لئے مختلف سیکولر پارٹیوں سے مل کر اس کا عملی نمونہ پیش کیا، اگرچہ وہ مسلم مجلس کے بانی اور اس کے صدر تھے، لیکن کانگریسیوں سے بھی ان کے تعلقات تھے، اور وہ بھی ان کی عزت کرتے تھے، ان کی موت پر مختلف طبقوں کے اکابر اور جن کو ان کی سیاست سے اختلاف تھا، انھوں نے بھی جو تاثرات ظاہر کئے ہیں وہ ان کی مقبولیت کے شاہد ہیں۔

Students’ Perceptions Toward Bilingual Education at Icp Chemistry Education in Makassar

This study aims to find out: (1) students’ perceptions toward bilingual education in ICP (International Class Program) toward the use of two languages of instructions (English and Indonesian) by the lecturer in classroom. (2) to investigate its benefit for students in ICP chemistry education. The researcher adopted a descriptive qualitative research with a case study method. To gain the data, the researcher employed questionnaire with the students. The subjects in this study were 24 of students sixth semester belong to the International Class Program (ICP) chemistry education in State University of Makassar. The results of this study showed that there were the bilingual education helps the students to gain control their English skill. It showed that students’ positive perceptions toward the use of bilingual language as language instruction in the classroom by the lecturer. It is concluded that teaching chemistry in English facilitates the learners’ attempt in learning English.

اردو زبان کا تاریخی و لسانی جائزہ: دکنی عہد سے بیسویں صدی تک

The topic of this dissertation is to evaluate historic and linguistic aspects of Urdu language (covering from Deccan Era to 20th century). The dissertation is divided into seven chapters to grasp and comprehend it well. These seven chapters are the reflection of poetry and prose which emerged under the influence of proclivity and concoction of renowned language and literature because it is intended to observe how conception and comprehension of language inspire human intellect, behavior and action. It also reveals that how by passing through evolutionary changes creativity and comprehension bring about maturity and stability in civilization and literature and under the influence of these changes what does a society expresses. In first chapter 'Urdu language of Deccan Era' is briefly evaluated. As Urdu language, its growth and its publication started from Deccan and then it got the status of official language.
