Diversification patterns within the Himalayan region have been paramount to the understanding of worldwide biodiversity. Apart from recent wide scale report, a hyperdiverse genus of the temperate region under angiosperm—Carex L. (Cyperaceae), consists of ca. 2100 species globally has not been examined in the Himalayan region, which covers 189 Himalayan Carex taxa. The timing, phylogenetic relationship and ecological diversification of Himalayan lineage in this remarkable genus were aimed to infer. Particularly inspected whether priority and adaptation to this ecological system, or both enlighten the success of radiation from the Kobresia clade (~ 60 species, among which ca. 40 are the Himalayan) of Himalayan Carex. The Phylogenetic patterns were evaluated employing maximum likelihood method (ML) of two (ITS and ETS) nrDNA regions and one (matK) plastid gene; the ML tree was used for time-calibration under penalized likelihood approach and with a fossil calibrated at the base of the tree. The estimation of phylogeographical reconstruction for ancestral ranges and historical processes was achieved with the model, dispersal-extinction-cladogenesis (DEC) implemented in BioGeoBEARS and reciprocal impacts of diversification were analyzed employing the model, geographic state speciation and extinction (GeoSSE). The climatic niche for all Carex species with available mapped georeferenced specimen data were assessed along with climatic records from WORLDCLIM, and therefore, niche evolution was estimated with a group of two models for adaptive range shift and inferring ancestral character states under Ornstein-Uhlenbeck (O-U) models and a Brownian motion model, respectively. During the exploration of Carex flora across the Western Himalayan range Carex simpliciuscula Wahlenb. (1803: 141), previously with doubtful record in the Flora of Pakistan, was confirmed for the region. The Himalayan taxa appears in three of the five reported major Carex clades, and characterized by multiple origins within each major clade. The oldest Himalayan Carex radiation was dated back to ~ 20 Ma, close the period of Himalayan orogeny, contributed to now abundant the Kobresia clade through longdistance migration from the region Nearctic. The Carex taxa in the Himalayas represents a heterogeneous model of diversifications derived from all through the cosmopolitan, however mostly temperate radiations. Several Himalayan radiations are relatively recently evolved, on the other hand, the most widespread and diverse Himalayan Kobresia radiation appeared at the lower Miocene. The timing and predominance of Hiamalayan taxa in Kobresia clade distributed in great elevation Himalayan meadows reveals that Kobresia may have eliminated other Carex taxa (non Kobresia) due to the consequence of mainly priority, competitive exclusion and historical contingency. A significant biodiversity needs to be discovered in order to explore new flora for the region. Around seventy specimens of 19 species collected with GPS reading of collecting sites from Western Himalayas (Pakistan) and 21 species requested from different herbaria, collectively made 40 for this study. Carex simpliciuscula, a new flora and numerous new collection localities for this region were explored. Additionally, morphological characters of pistillate scales studied particularly under scanning electron microscope seem to contribute to identifying taxa for the region. Therefore, these findings encourage further research on micro- and macromorphological studies of pistillate scales in Carex.

اہلیہ سید سلیمان ندوی

اہلیہ محترمہ مولانا سید سلیمان ندوی ؒ
کراچی کے ایک مکتوب سے یہ المناک خبر ملی کہ استاذی المعظم حضرت مولانا سید سلیمان ندویؒ کی اہلیہ محترمہ ۲۳؍ جولائی ۱۹۸۷؁ء کو اپنی اولاد کو آنسوؤں کے سیل رواں میں چھوڑ کر عالم جاودانی کو سدھاریں۔ اِنَّا ﷲ وَاِنَّا اِلیہ راجعون۔
یہ تعزیتی تحریر دارالمصنفین کے احاطہ میں اس گھر میں لکھی جارہی ہے جہاں حضرت استاذی المحترم نے اپنی زندگی کے بہترین بلکہ بہار آفریں اور مشک آگیں دور گزارے ہیں، وہ یہاں کے کتب خانہ میں اپنی میز پر سیرۃ النبیؐ، معارف کے شذرات، علمی، مذہبی اور ادبی مضامین میں اپنے علم و عرفان کے مروارید، نظر و فکر کے زمرد اور ادب و انشا کے درشا ہوار بکھیر کر داخل ہوتے تو پہلے اپنی سب سے چھوٹی اولاد کو اپنی آغوش شفقت میں لیتے، پھر ان کی اور اولادیں ان کے یمین ویسار میں سما جاتیں، جس کے بعد علمی میز پر ان کو جو تکان ہوتی وہ یکایک دور ہوجاتی، اور ان کے چہرے پر بشاشت، ان کی ہر ادا میں نزہت اور ان کی بزرگی میں روحانیت دکھائی دیتی، وہ اپنے بچوں کے شگفتہ چہروں کو دیکھتے تو ان کی آنکھیں جنت بن جاتیں، ان کی معصوم باتوں کو سنتے تو ان کے کان فردوس گوش بن جاتے، پھر فضا میں پدری مہرومحبت کی کوثر و سلسبیل نظر آتیں، اسی فضا میں ان کی اہلیہ محترمہ نے بھی زندگی گزاری، اس گھر میں وہ تقریباً ۱۰ برس رہیں۔
سید صاحب اپنی گھریلو زندگی میں بہت ہی نفاست پسند تھے، ان کی ہر چیز بہت سلیقہ، صفائی اور ستھرائی سے رہتی، مرحومہ بھی فطری طور پر بہت ہی سلیقہ مند، مہذب، عبادت گزار اور باوقار تھیں، جس سے سید صاحب کو اپنی زندگی میں بڑی مدد ملتی رہتی، دارالمصنفین کی قلیل آمدنی میں دونوں...

IMPLEMENTASI BLENDED LEARNING DALAM MATA KULIAH ULUMUL QURAN PADA PASCASARJANA UNIVERSITAS ISLAM NEGERI ALAUDDIN MAKASSAR

This study aims to see the implementation of blended learning in Ulumul Qur'an courses at uin Alauddin Makassar Postgraduate. The method used in this study uses a type of qualitative research related to the implementation of Blended Learning Courses Ulumul Qur'an at the Postgraduate UIN Alauddin Makassar. The results showed that: (1) the description of the model of implementation of the implementation of the study blended Ulumul Qur'an courses at the Postgraduate UIN Alauddin Makassar using a dual-system that is a combination of conventional systems with online. More use of online learning systems during the Pandemic (80%) compared to traditional face-to-face learning systems. The merger of the two systems includes the incorporation of learning resources as well (learning modules, textbooks, and journals), the implementation of learning (online discussions, watching videos, and accessing supporting resources, and the incorporation of a learning evaluation system, including standardized assessment through quizzing, midterm exams, and final exams.

An Analysis of the Role of Independent Power Producers in the Gross Domestic Product and Demand for Energy in Pakistan 1990-2015

Pakistan is a country having more than 207.77 million people, where almost 61 percent of population is living in rural areas (Planning & Development Division, Federal Bureau of Statistics, 2015). In both urban and rural areas, energy is considered as important element to run daily economic activities. The energy crisis remained one of the main obstacles in the way of development since independence. The situation of electricity is worsening day by day, and worsened in the rural areas as compared to urban areas. Pakistan has made no considerable progress for overs of decades to overcome this problem due to an effective planning and proper implementation of energy policies and lack of infrastructure. The focus of the study is to find-out the impact of Independent Power Producers (IPPs) on Gross Domestic Product (GDP) and demand for energy in Pakistan. For this purpose data was collected from Economic Surveys of Pakistan (2015), Pakistan Bureau of Statistic, IPPs yearly books and World Development Indicator, for the period of 1990 to 2015. The study aimed to find-out the determinants of energy demand and supply in Pakistan and to examine the impact of IPPs on economic growth of Pakistan. The study employed Autoregressive Distribution Lag (ARDL) model to build up the relationship between various explanatory variables and dependent variable. The impact of different variables was observed on energy demand, energy supply and Gross Domestic Product of Pakistan in the context of IPPs. The first model of the study was constructed to find out the impact of oil prices and energy supply on energy consumption. The results show that energy supply and oil prices affect positive and significant impact on demand of energy both in the short run and long run. It was found that 1 percent increase in energy supply and prices, increases energy consumption by 0.34 and 0.54 percent respectively in the long run. The second model was constructed to analyze the impact of certain variables like Gross Fix Capital (GFC) formation, Foreign Direct Investment (FDI), labor participation, oil prices and energy balance on energy supply in Pakistan.It was concluded that except oil prices, all the variables has significant and positive effect on energy supply except oil prices, which has a negative impact on energy supply both in the long and short run. The most important objective of the study is to examine the role of IPPs in Gross Domestic Product (GDP). It was observed that IPPs are playing positive role in increasing economic growth of the country, even though they are producing below their capacity still their impact is positive. The same variables were used for GDP as were chosen for energy supply. Where labor participation and oil prices showed negative results. It was found that labor participation in IPPs and increase in oil prices decreases economic growth by 0.08 and 0.01 percent respectively, while capital formation increased GDP by 0.30 percent in the short run and 0.88 percent in the long run. The effect of FDI was surprising, in the short run it has a negative associated with on GDP but in the long run it showed positive association with GDP. The study determined that IPPs are the asset for Pakistan, not only to fill the gap of electricity but also to increase GDP of the country. It is suggested that to increase supply of electricity, government should utilize its resources to install new power plants and encourage more IPPs by relaxing agreement in an area where there is more issue of energy, so that supply of energy can be increased in the country. Government of Pakistan should allow foreign investors to operate their plant wherever they want according to the feasible requirement of the area. All kind of restrictions should be removed while preparing operational policies for IPPs.
