Desertification has emerged as a major environmental problem during last few decades. Due to its serious implications on food security it has attracted global recognition. Significant attention is being given to its mitigation both at government and non-governmental levels. Some of the efforts carried out by state sponsored agencies and NGOs have turned into success stories. However, it has been noticed that if the problem persists for a long time due to lack of attention then land restoration becomes ecologically and financially expensive. Therefore its earlier diagnosis and treatment can not only reduce the cost but is also beneficial for human welfare. Pakistan has substantial land susceptible to desertification due to geographical factors such as topography and aridity and social issues like rapid population growth and socio-economic changes. The pressure on land often leads to its un-sustainable land use leading to desertification. Millions of poor farm households and their livelihoods in arid and semiarid areas of the country are prone to risks and uncertainties associated with desertification and land degradation. Inhabitants of the areas affected by desertification try to adapt to changing environment and cope with emerging problems within their own limited knowledge and capacity.Some of the adaptation strategies like social values and norms are built in the traditions of the society. In addition, farmers try to learn from their experiences. Their efforts need to be supported as much as possible. Technology transfer and extension on conservation practices and selection of suitable and better adopted plant varieties and livestock breeds could be of substantial help in that direction. Further, financial assistance through farm credits could also help poor farmers to invest in their lands for improving its productivity. The present study of Karak district of Khyber Pakhtunkhwa has been undertaken to portray a case study in Pakistan in an area prone to and affected by desertification. It would provide an insight not only into the causes of desertification in a semiarid area but also into workable alternatives adapted locally for the sustainable management of land resources. It would also help in policy formulation and provide guidelines for decision-making to combat desertification. Data regarding physical parameters in this study were obtained using modern tools like remote sensing and GIS for mapping the area affected or at risk from desertification. The data on social parameters were collected through household surveys and focused group discussions that were analyzed following its processing with SPSS. Results obtained from this study reveal declining land productivity (both crops and rangeland), crop failure, and increased cost of agriculture, pointing a finger towards increasing desertification and land degradation. Both natural and anthropogenic factors are responsible for increase in desertification. Among natural factors enhanced aridity (water scarcity) as well as erosion of soil by wind and water are prominent. In terms of anthropogenic factors, over exploitation of resources, whether through cutting of vegetation, cultivation of farmland or livestock grazing is the main culprit. In order to reduce their dependence on land many people have migrated to earn income from nonfarm sources. However, while providing extra income, migration has also resulted in dearth of farm labor, often leading to abandonment of cultivated land opening them to erosion and desertification. Nevertheless remittances from migrants have also helped in certain cases to enhance investment in land for increasing productivity through increase of farm inputs. Finally, this study noted that the practice of traditional values for the control of desertification, which had declined with time are now being revived to control the overexploitation of resources, a good sign for future desertification control in the area.

مولانا فضل اﷲ الگیلانی

سید فضل اﷲ الگیلانی
افسوس ہے ہماری بزم علم وفضل کی ایک اورشمع روشن بجھ گئی، یعنی ۲۳/مئی کو مولانا سید فضل اﷲ الگیلانی نے۷۸ برس کی عمر میں علی گڑھ میں وفات پائی اور یونیورسٹی کے قبرستان میں مدفون ہوئے۔اناﷲ واناالیہ راجعون۔حضرت مولانا محمد علی مونگیری جن کاسلسلۂ نسب باپ کی طرف سے حضرت شیخ عبدالقادر جیلانی تک پہنچتا ہے مولانا کے دادا تھے۔ والد یعنی مولوی احمد علی کاانتقال جوانی میں ہوگیا جب کہ مولانا صرف سات برس کے تھے، اس لیے دادا نے آپ کو تربیت میں لے لیا اورمونگیر میں رہ کرآپ نے علوم دینیہ واسلامیہ کی تکمیل کی۔ بعض کتابوں کا درس مفتی عبداللطیف سے بھی لیا جوبعد میں آپ کے خسر بھی ہوگئے۔ تعلیم سے فراغت کے بعد عثمانیہ یونیورسٹی حیدرآباد کے شعبۂ دینیات میں لیکچرر ہوئے۔ ۱۹۵۶ء میں،۱۹۵۷ء میں ریڈر اورصدر شعبہ کی حیثیت سے سبکدوش ہوئے۔اس کے بعد آپ نے کاروبار شروع کردیا اور ملازمت کبھی نہیں کی۔
مولانا علم وفضل کے اعتبار سے سلف صالحین کانمونہ تھے استعداد نہایت پختہ، مطالعہ بے حد وسیع اورنظر دقیق تھی۔ان کوسب علوم سے یکساں مناسبت تھی، مطالعہ اور درس کے دھنی تھے، لکھتے کم تھے مگر جب کبھی لکھا بہت خوب لکھا، چنانچہ امام بخاری کی کتاب’’ ادب المفرد‘‘ کی جوشرح دوجلدوں میں مرحوم نے لکھی اورمدینہ سے شائع ہوئی ہے۔تحقیق اوردقت نظر کاشاہکار ہے۔ اس کے علاوہ چند چھوٹے بڑے رسالے جو بعض جزئی مسائل پرلکھے گئے ان میں بھی تحقیق کی یہی شان ہے۔ عملاً نہایت عابدوزاہد اورصاحب اورادوظائف، جماعت سے نمازادا کرنے کااہتمام سخت معذوری کی حالت میں بھی کرتے تھے۔ اخلاق وعادات کے اعتبار سے بڑے متواضع،خوش مزاج،باوضع اورقلندر منش انسان تھے۔ضرورت مندوں کی مدد کرنے میں انہیں خوشی محسوس ہوتی تھی۔ برسوں سے دارالعلوم دیوبند کی مجلس شوری کے ممبر تھے اُس کے جلسوں میں پابندی...

Application of Diabetes Self Management Education (DSME) in Patients with Type 2 Diabetes Mellitus based on Blood Glucose Levels

Diabetes Self Management Education (DSME) uses guidelines, counseling, and behavioral intervention methods to increase knowledge about diabetes and improve individual and family skills in managing diabetes mellitus (DM). This research is a quantitative study using a pre-experimental design that provides treatment or intervention to the research subjects then the effect of the treatment is measured and analyzed. This design is used to compare the results of the intervention of the application of Diabetes Self Management Education (DSME) on controlling blood glucose levels in patients with type 2 diabetes mellitus. The analysis used the dependent t-test / paired t-test. The results showed that there were significant differences in blood glucose levels in the measurement after giving DSME to the respondents, indicating that the measurement of blood glucose levels after treatment was smaller than the measurement before treatment. It is necessary to develop a program to increase the competence of nurses in nursing care for diabetic clients and education related to diabetic self-care to increase the knowledge and skills of nurses in managing diabetes.

Synthesis and Characterization of Zinc Oxide Films and Nanostructures

Zinc oxide (ZnO) is a material of interest for extensive research due to its numerous beneficial properties and wide range of applications. In this work, thin films of ZnO have been deposited by rf magnetron sputtering. The effect of varying thickness on the structural properties of the films have been studied. The crystallinity shows improvement with increasing thickness. The surface morphology is granular for all films and roughness increases with increasing thickness. Nanorods of ZnO have been synthesized via hydrothermal route. It has been shown that the diameter of nanorods increases with increasing solution concentration and with increasing thickness of seed layer. However the diameter decreases with increasing roughness of the seed layers. The number density shows inverse behavior to that of diameter. The covered area and growth rates of nanorods were also estimated. Use of thick seed layers and higher solution concentration led to formation of film like array of nanorods covering almost the entire substrate surface. A new model has been proposed for the growth of ZnO nanorods. This model is based on the Avrami model and estimates the number density of nanorods as a function of solution concentration. To the best of the author’s knowledge, Avrami equations have not been modified for nanostructures in terms of solution concentration. Zinc Acetate, Sodium Dodecyl Sulfate and Trisodium Citrate have been used to modify the structure of nanorods. Each agent had a different influence on the structure evolution of ZnO nanostructures. The growth mechanism in the presence of these agents have been discussed in detail. Use of Sodium Dodecyl sulphate and Trisodium Citrate have shown potential for growth of continuous granular films via the simple and inexpensive hydrothermal method.
