آصف فیملی پارک دی سیر
آصف فیملی پارک میں پہلی وار ویکھیا
اجمیری مسجد دا سوہنا گنبد باشکل مزار ویکھیا
الحاج احمد علی ہے نیک نمازی بندہ رب دا پیارا
مسجداں اُتے خرچ کریندا اوہدی زندگی دا ورتارا
بہاول نگر دی ممتاز شخصیت عزت کرے جگ سارا
غریباں تے مسکیناں دا اوہنوں غمخوار ویکھیا
ایڈا سوہنا فیملی پارک ہر کوئی ویکھن آوے
ویکھن والا دوجی واری فیملی نال لیاوے
رات گئے تک گھمے پھرے اوہ بہتیاں خوشیاں پاوے
میں وی جا جا پارک نوں ہے بار بار ویکھیا
پارک دے وچ گھمن والے رج رج خوشیان پاون
ہر طرح دے کھانے پکن جو دل چاہوے کھاون
چنگے ذائقے والی چائے ٹھاکر ہوریں پلاون
ایہو جیا ذائقہ تاں اساں نہ کدی بازار ویکھیا
کڑیاں وی کدی سیر بہانے فیملی دے نال آندیاں نیں
مہک پھلاں دیں پہل موراں دی پیاں اپنا دل پرچاندیاں نیں
دوجی واری نال سہلیاں ول ول اوتھے آندیاں نیں
کشتی رانی دے وچ وی بیٹھیا میں انہاں نوں کئی وار ویکھیا
سوہنی اُچی پہاڑی ویکھ کے خوشیاں ہون دوبالا
مست ہوا دے جھولے آون کوئی سمجھے درداں والا
ملے سکون تے فرحت ایتھے دکھ رب کریم نے ٹالا
مہماناں نے وی ایہہ رونق میلا عین جاندی واری ویکھیا
فیملی پارک دے کبوتر وی پئے ہو ہو کردے نیں
بند ر بچیاں کولوں چیزاں لے لے پیٹ اپنا پئے بھردے نیں
موراں نے جد پہلاں پایاں خوشی دے بدل ورہدے نیں
نقد و نقد ی خوشیاں ملیاں ناں اساں کدی اودھار ویکھیا
ساز آواز سریلی ایسی دل چ اتردی جاوے
عطاء اللہ دی طرز سی ساری ہر ہک نوں پئی بھاوے
کونج وچھڑ گئی ڈاروں ایویں وچھڑیاں دی...
Agile methods of software development have been used widely over the last decade, and the majority of organizations have now embraced them in their projects. Thus, the current study explored the positive influence of agile practices on individuals' intentions to stay at their employment. In accordance with this objective, the study looked at the role of job characteristics in mediating the association between agile methods and intention to stay. A sample of 486 employees was contacted through online survey using the Google Forms platforms during the period of September 2021 who practice the agile methods while working at their organizations. They provided data on the questionnaires of agile practices, job characteristics, and intention to stay. Findings postulated that agile practices have significant impact on employees’ intention to stay. Results further reported the significant mediation through job characteristics between agile practices and intention to stay. Findings showed that the job when is designed on feedback, skill variety, job autonomy, task identity and task significance mediate an impact of practising agile methods on intention to stay.
Analysis of non-Newtonian fluids is now recognized very well for its several engineering and industrial applications. Motivation of researchers in these materials is through food products (mayonnaise, milk, apple sauce, ketchup, chocolates in liquefies form, yogurt, alcoholic beverages, ice creams etc.), biological material (vaccines, syrups, blood, synovial fluid etc.), chemical material (cosmetics, shampoos, tooth pastes, pharmaceutical chemicals, grease, paints, oil reservoirs etc.). Such materials do not obey the Newton''s law of viscosity. Rheological features of all the non-Newtonian materials are not concluded by one constitutive relation. Therefore numerous models of such fluids have been recommended for the discussion about their diverse characteristics. The non-Newtonian fluids at present are argued through three main classifications i.e., (i) Rate type (ii) Differential type and (iii) Integral type. In addition the features of such materials passing towards a stationary/moving surface have key importance in paper production and glass fiber, polymer and metal extrusion mechanisms, rubber sheets and drawing of plastics, cooling of metallic surfaces and crystal growth. The analysis of heat transfer aspects through a cooling rate is crucial to achieving the best quality product. Features of heat transfer is based through involvement of various mechanisms i.e., thermal radiation, heat generation/absorption, Fourier''s law of heat conduction, convection and Newtonian conditions. Having all such aspects in mind, the modeling for flows of non-Newtonian fluids through different physical conditions is made. Solutions and analysis are carried out by utilizing homotopy analysis technique. Finally the structure of the thesis is governed as follows. Chapter one consists of literature review of relevant published works. Expressions for Jeffrey, Walter-B, thixotropic and third grade fluids are included. Basic concept of homotopy analysis method is also presented. Chapter two addresses the mixed convection flow of Jeffrey material by an inclined impermeable stretching cylinder. Feature of heat transport are examined via thermal radiation and non-uniform heat source/sink. Convective conditions for heat and mas transfer are imposed. Implementation of appropriate transformation leads to partial differential systems into ordinary ones. Resulting systems are driven through homotopic technique. Aspects of sundry physical variables on the flow field are discussed graphically. Numerical values are constructed for the behavior of distinct variables versus coefficient of skin friction, local Nusselt and Sherwood numbers. The contents of this chapter are published in Plos One 12 (2017) e0175584. Chapter three explains the nonlinear convective flow of magneto Jeffrey nanomaterial.
