In this work new results regarding the behavior of some non-Newtonian fluids in different circumstances will be presented. Such results refer to different motions of Maxwell, Oldroyd-B fluids and Burgers’, fluid with fractional derivatives model and ordinary Oldroyd- B fluid. Motion of fractional Maxwell and Burgers’ fluid is studied between two sliding cylinder which are sliding along their common axis with time dependent velocities, and flow of fractional Oldroyd-B fluid is studied between two rotating cylinders which are rotating about their common axis with time dependent angular velocities. Taylor-couette flow of an Oldroyd-B fluid in an annulus is studied in which the motion is produced due the time dependent torque on the inner cylinder. The flow of generalized Maxwell fluid over an oscillating flat plate with constant temperature at the boundary is also studied. The integral transforms technique will be used to find the solutions. The obtained results will satisfy all the governed initial and boundary conditions. The solution corresponding to particular cases will also be obtain as liming cases of our general results. Finally, the obtained results will be analyzed numerically by making graphs using computer algebra system (CAS).

ہر چند شاعری تخلیقی محرک کی محتاج ہوتی ہے مگر موضوعی شاعری دراصل اس وقت زور دارہوتی ہے جب فیضان و عقل، جذبِ درروں اور بیدار قوتِ فیصلہ یا پھرشعور و لاشعور کے دھارے آپس میں مل جاتے ہیں۔یہ وہ مقام ہوتا ہے جہاں عرفان و وجدان اور فہم وخرد کی توانائی ایک دوسرے کو سہارتے ہوئے باہم آمیز ہو جاتے ہیں۔یہ حقائق اپنی جگہ بجا لیکن جب بھی کسی تخلیق کار کو اخلاقی موضوع کا سامنا کرنا ہوتا ہے تو شرطِ اوّل کے طور پر ذہنی وقلبی،نزہت و متانت ، نیاز مندی ،عاجزی و انکساری اور مثالی اسلوبِ کلام کا حامل ہونا لازم آتا ہے۔متحرک و منور اسلوب کی بنیادی غذا ،تخلیق کار کی شخصیت، حُبِ موضوع ،مقام کا حاملعلم و کردار ،تقویٰ و ایمان ،طبعی مناسبت، تہذیب کے اِساسی زاویوں سے آگاہی اور وفورِ شوق سے تیار ہوتی ہے۔اردو نعتیہ سرمائے کی متنوع جہات میں سیرتِ النبیﷺ کے حتی الامکان پہلوئوںکواجاگر کرنا کسی بھی شاعر کے لیے آزمائش سے کم نہیں ، پھر اس سے بڑی آزمائش ہیئت مسدس میں اظہار، جس کا مزاج ہمیشہ متقاضی رہا ہے کہ مترنم اور رواں دواں وسہل اوزان کے ساتھ ساتھ دلوں میںاترتا شفاف کومل لہجہ اورآبِ زُلال سے دھلی زبان شیتل سی مخمور لے پوری قدرتوں کے ساتھ بہم ہو۔میں سمجھتا ہوں کہ یہ سب لطائفِ پر نور روحِ بندگی سے میسر آتے ہیں۔ اگر ایسا نہ ہو تو معلومات کو شعر میں لانے سے ثقالت کا احساس حاوی رہتا ہے، جس کامسدس متحمل نہیں ہو سکتا۔
انھی موضوعی اور معروضی خوبیوں کے سبب پورے وثوق سے کہا جا سکتا ہے کہ مسدس ہی ایک ایسی صنفِ سخن ہے جسے دنیا بھر کی مستند و اعلیٰ نظموں کے مدِ مقابل رکھا جاسکتا ہے۔

A Study of Learning Styles and Their Relationship With Emotional Intelligence of Students at University Level: A Case Study of Abdul Wali Khan University Mardan.

Teaching – learning is an inclusive process involving many factors like motivation, intelligence, memory, interest, creativity etc. Some of the recently focused such factors are learning styles and emotional intelligence. Learning style refers to an individual’s preferred mode of acquiring knowledge. Similarly, emotional intelligence denotes a person’s capacity to asses, use and manage personal and others’ emotions. Both of these constructs are vital to learning and achievement. Individuals are different with respect to their learning styles and levels of emotional intelligence. Preferring a specific mode of learning reveals emotions of liking for it. Apparently, these constructs seem to be related as both involve emotions and cognition. This study attempted to highlight the distribution of learning styles and emotional intelligence of the university students along with determining the existence, nature and degree of relationship between them. The theoretical framework was taken from the FelderSilverman Model of Learning Styles (1988) and Davis, Stankov and Roberts’ (1998) conception of emotional intelligence. The objectives of this enquiry were: (1) To identify different learning styles of university students on gender bases, (2) To compare learning styles across disciplines, (3) To determine the levels of emotional intelligence of university students on gender bases, (4) To compare emotional intelligence across disciplines and (5) To find the relationship between learning styles and emotional intelligence. It was a descriptive-correlational enquiry which involved collection of quantitative data through a survey. The population of the study was consist of students of all five faculties of Abdul Wali Khan University Mardan. The cluster sampling technique was used to collect data from the final year students of the 15 selected departments under five faculties. The data were assembled through two standardized tools. The Index of Learning Styles (ILS, Felder & Spurlin, n.d.) was used to ascertain learning styles while Wong and Law Emotional Intelligence Scale (WLEIS, Wong & Law, 2002) was exercised to establish the levels of emotional intelligence. Prior to administering, these tools were passed through validity and reliability in the local context through pilot testing. Afterwards, these tools were dispensed to the sampled learners. The collected data were analyzed by means of percentage, mean, t-test, ANOVA, Tukey test and correlation. The findings revealed that visual, sensing and active styles of learning were highly preferred. In terms of emotional intelligence, majority of the students excelled on ‘self-emotion appraisal’ and fall behind on ‘regulation of emotion.’ In addition, female students subjugated all components of emotional intelligence. Moreover, significant differences of learning styles and emotional intelligence were indicated across gender and disciplines. The ttest findings revealed that female students were significantly superior (t (826) = - 2.135, р = .033 < .05) to male students on visual – verbal facet. Likewise, on emotional intelligence, female students were also meaningfully superior to male students on ‘self-emotion appraisal’ (t (826) = -2.475, р = 0.014 < 0.05) and ‘overall emotional intelligence’ (t (826) = -2.058, р = 0.04 < 0.05). In terms of relationship, the findings implied lower levels of correlations in general. Generally, the active – reflective and visual – verbal aspects of learning styles indicated low positive while sensing – intuitive aspect implied low negative association with the various facets of emotional intelligence. In terms of recommendations, the study suggested the improvement of curricula keeping in view the learning styles and emotional intelligence of the students. Also, the weak area of emotional intelligence, particularly ‘regulation of emotion’ has been addressed for improvement. In addition, new venues for research were also suggested. This study has wide implications for teachers, curriculum designers, students, educational psychologists and researchers.
