مولانا عبدالباری حاوی

مولانا عبدالباری حاوی
افسوس ہے گذشتہ ماہ ہمارے نہایت فاضل دوست مولانا عبدالباری صاحب حاویؔ نے بھی ہوائی جہاز کے ذریعہ حج کے ارادے سے جاتے ہوئے ظہران میں وفات پائی۔انا ﷲ وانا الیہ راجعون ۔مولانا وانمباڑی(شمالی ارکاٹ) کے باشندہ تھے اوروہیں حضرت مولانا گنگوہی حضرت شیخ الہند اورمولانا تھانوی کے ارشد تلامذہ سے علوم و فنون اسلامیہ ودینیہ کی تعلیم پائی۔یوں توسب علوم وفنون میں کامل درک رکھتے تھے لیکن حدیث اورعربی ادب میں بڑا کمال حاصل تھا۔ پہلے مختلف مدارس اورایک ہائی اسکول میں درس کی خدمات انجام دیں، اب ادھر دس برس سے مدراس کے مشہور جمالیہ عربک کالج میں صدر الاساتذہ کے عہدے پرفائز تھے۔عربی زبان اوراردو وفارسی میں شعر کہتے تھے۔ پہلے تخلص مجاہدؔ تھا پھر حاویؔ کے تخلص سے مشہور ہوئے ۔بڑے خوش اخلاق اورعابد و زاہد بزرگ تھے۔ وضعداری، مروت اورشرافت ان کی فطرت تھی۔جیسا کہ سفرنامہ مدراس میں عرض کیا جاچکا ہے علالت اورضعف کے باوجود راقم الحروف سے ملاقات کے لیے قیام گاہ پرتشریف لائے۔سات آٹھ مرتبہ حج وزیارت مدینہ سے مشرف ہوچکے تھے۔اس مرتبہ پھر جارہے تھے کہ اثنائے راہ میں پیغامِ اجل آپہنچا۔عمرساٹھ کے لگ بھگ ہوگی اﷲ تعالیٰ صدیقین وشہداء کامقام عطا فرمائے۔ آمین۔ [مارچ ۱۹۷۲ء]

 

Exploring the Challenges Faced by The Teachers in Developing Higher Order Thinking Skills Among Students at Higher Education Level

This study was designed to describe the importance of higher order thinking skills (HOTS) among students by the teachers; to analyze the availability of instructional facilities and to explore the challenges faced by the teachers in developing higher order thinking skills among students at higher education level. The theoretical framework of the study was based on the model of Bloom’s revised taxonomy and higher order thinking skills by Mishra & Kotecha (2016). The model based on six dimensions named as remembering, understanding, applying, analyzing, evaluating and creating. The research approach was qualitative with case study research design. The population of the study was based on faculty members of the three different departments of the National university of Modern Languages, Islamabad. Convenient sampling was used as the sampling technique. Data was collected by open ended questionnaire. Data was analyzed by categories and sub-categories after that researchers established codes from the responses of the faculty members. The findings of the study revealed that higher order thinking skills are important because it help us to develop critical thinking skills and creativity. Teachers faced many challenges during the class like lack of time, cooperation among students, diverse mental level, large number of students and lack of physical resources. These challenges can be tackled by motivation and suitable teaching method.

Nonlinear Wave Propagation in Photonic Band Gap Materials

This research work is concerned with the nonlinear wave propagation in photonic band gap (PBG) materials. Photonic band gap materials are artificial periodic structures that exhibit bands and gaps for the propagation of light in certain frequency ranges depending on the periodicity of the structure. Nonlinear PBG materials can be defined as the periodic structures that have the ability to control light with light and produce a structural enhancement of nonlinear effects. The optical properties of such materials can show dramatic changes with the changing intensity of light. An interesting manifestation of nonlinear effects in these structures is the formation of gap solitons and the associated phenomenon of optical bistability. Promising applications for such phenomena include optical switches, logic gates, transistors etc. Recent theoretical and experimental studies have suggested the possibility of creating artificial metamaterials that can possess a negative real part of magnetic permeability and/or a negative real part of electric permeability and are known as double and single negative metamaterials (DNG, SNG). The main focus of the present study is to explore the new features of the nonlinear wave propagation due to the inclusion of double negative and single negative metamaterials in PBG structures. The conventional PBG structures are characterized by Bragg gaps whereas in PBG structures containing DNG and SNG metamaterials, mechanisms other than Bragg reflections can produce gaps such as the zero-n and the zero- φ eff gaps. The real advantage of these new gaps is the fact that these are relatively insensitive to the incident angle and disorders in the structures. iiIn the present work we have considered only one-dimensional structures. The transfer matrix approach and the characteristic matrix approaches are mainly used to study the wave propagation through these structures. We have also applied the Kronig-Penney delta function approach in one of our investigations. The electric field profiles for the zero-n gap soliton, zero-φ eff gap soliton and Bragg gap soliton are plotted and a comparison of their characteristics is made. Similarly the optical bistability curves for the one-dimensional structure containing alternate DNG and regular materials and containing SNG materials are also plotted. We have considered normal as well as oblique incidence. The properties of an angular gap in one-dimensional structures containing SNG layers are investigated. We have also investigated some defect structures. The properties of the resulting localized mode are studied. The results of the investigations are summarized at the end.
