کمپیوٹر عصر حاضر کی اہم ضرورت
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اسا تذہ کرام اور میرے ہم مکتب ساتھیو!
آج مجھے جس موضوع پر اظہار خیال کرنا ہے وہ ہے:’’ کمپیوٹر عصر حاضر کی اہم ضرورت‘‘
کمپیوٹر عقلِ انسانی کا اک انعام ہے
زندگی کا سہل اس کے دم سے ہر اک کام ہے
صدرِذی وقار!
قوموں کی زندگی میں کچھ لمحات ایسے آتے ہیں جو ان کی زندگی میں امر ہو جاتے ہیں۔ قرآنِ پاک میں ہے کہ انسان کے لیے کائنات کی ہر چیز مسخر کر دی گئی ہے۔ ہر چیز انسان کے تابع ہے، انسان جب چاہے، جہاں چاہے اور جیسے چاہے کائنات کے ذرے ذرے پرحکومت کر سکتا ہے، قرآن پاک کی اس آیت نے اہل لب کی زندگی میں انقلاب برپا کر دیا، اور کمپیوٹر کو دیکھ کر قرآن پاک کی یہ حقیقت تو اور بھی الم نشرح ہو جاتی ہے کہ کائنات کی ہر چیز مسخر کر دی گئی ہے۔
جنابِ صدر!
کمپیوٹر عصر حاضر کی اہم ضرورت ہے ، یہ ہمارے لاکھوں مسائل حل کر دیتی ہے۔ کمپیوٹر کی ایجاد ایک ایسی ایجاد ہے کہ ہماری بے شمار مشکلات آناًفا ناًدرست انداز میں حل کر دیتی ہے، یہ اعدادوشمار کو جمع کرنے اور ان کا تقابلی جائزہ لینے کے کام بھی آتا ہے، دوسرے الفاظ میں اس کی اپروچ اور ڈاٹا کاعمل انسانی دماغ سے کئی گنا بہتر اور جلدحل ہوجاتا ہے یہ معلومات کو print کرنے کی صلاحیت بھی رکھتا ہے۔
صدرِ ذی وقار!
کمپیوٹر عصر حاضر میں اللہ تعالیٰ کا انعام ہے، ایک عظیم نعمت ہے، ایک نفع بخش ایجاد ہے، جس طرح اللہ تعالیٰ نے دنیا کے لیے اپنی نعمتوں کی فراوانی فرمائی ہے، اپنے انعاماتِ رفیعہ سے عوام النّاس کو نوازا...
The travel and tours enterprise were badly affected due to pandemics. In the aftermath of high restrictions on human movement, travel-based entrepreneurs were highly impacted due to lockdown. Due to pandemic, highly impacted into earning-saving, lack of supportive working conditions, lower self-capacity, and lack of recovery budget and policies, the travel and tours-based entrepreneurs were highly impacted. The study reflected the impact of pandemics on travel and tours, major constraints, and a possible way forward to sustaining. The research explores what are the major existing practices of sustaining travel and tours entrepreneurs during pandemics, what factors can contribute to building bounce-back capacities of travel and tours entrepreneurs’ sustainability. Above forty-four, snowball-based sampling was done from major travel and tours entrepreneurs, Pokhara-Nepal. A structure-based open-ended questionnaire, key informant interviews, and in-person-based discussion were applied in the method of study. Used the content analysis along with a recap of the research question, undertake bracketing to identify biases, operationalize variables with develop a coding, and code the data with undertaking analysis while qualitative analysis, and multiple regression facilitated on quantitative analysis to finalize the discussion. The study reflects that self-saving, social support, state and financial institutions recovery support, social behavior and change communication, full vaccination practices, and self-accountable tourist behavior are highly expectable conditions to the sustainability of travel and torus entrepreneurship in the learning area. The study concludes that self-saving capacity can contribute to bounce-back capacity for every entrepreneur. Social support and socioeconomic recovery packages were also contributing to sustaining travel and tours in the study area. Self-saving condition and capacity is higher bounce back capacity compared to non-saved entrepreneurs in the study area. Social support, socioeconomic recovery practices, and recovery packages from state and financial institutions were not at the higher level as expected.
Incorporation of well-defined functional filler into a polymer matrix to form inorganic/organic composites with tailored properties represents new chemical feedstock advancement. In this work, functionalized polyhedral oligomeric silsesquioxane (functional silsesquioxane) and quaternary ammonium compound immobilized metal graphene oxide (functional graphene oxide) hybrids with defined architectures were synthesized by wet chemical methods. The synthesized functional fillers were thoroughly characterized by using various techniques including electronic absorption (UV-Vis), X-ray diffraction, scanning electron microscopy (SEM), optical microscopy, Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), Raman Spectroscopy, and dynamic laser light scattering (DLS). Functional silsesquioxane was incorporated into two polymer matrices, non-reactive and reactive, to achieve inorganic/organic composites. Poly(vinylidene fluoride-hexafluoropropylene) (PVdF-HFP) as non-reactive polymer matrix and poly(pyromellitic dianhydride-co-4, 4′-oxydianiline), amic acid solution as reactive polymer matrix were used. Functional graphene oxide was incorporated in poly(methyl methacrylate)/poly(ethylene glycol) (PMMA/PEG) blend matrix to achieve inorganic/organic composite. All the composites were prepared by low cost solution casting method. The physiochemical properties of the prepared composites were examined by using different techniques. The prepared composites analysis by FTIR, XRD, TGA, differential scanning calorimetry (DSC), and SEM indicated that the functional fillers were bonded through different set of interactions including electrostatic, van der Waal and hydrogen bonding and dispersed uniformly into the polymer matrices. The prepared composites showed excellent antifouling and antibacterial performances for bovine serum albumin (BSA) protein and Escherichia coli (E. coli) bacteria, respectively. In addition, the prepared composites performance was checked with pure water flux and gas permeability/selectivity studies. The present study would be providing advantages over existing methods to prepare nanofiller/polymer composites such as low cost, proper dispersion of fillers that would allow obtaining excellent structural, thermal, optical and surface properties of polymer nanocomposite/nanohybrids for applied water treatment and other environmental applications.
