علامہ اقبال کی طلباء سے توقعات

علامہ اقبال کی طلبا سے توقعات
طالب علم کو ہر شخص بنظر استحسان دیکھتا ہے اپنی پہلی نظر میں جو تصور اُس کے ذہن میں آتا ہے وہ یہی ہوتا ہے کہ یہ بچہ بڑا ہو کر ملک و قوم کی خدمت کرے گا، ماں باپ کی فرمانبرداری کرے گا، ہر ایک کے ساتھ حسنِ سلوک کے ساتھ پیش آئے گا۔ اور وُہ طالب علم بھی بڑا خوش نصیب ہے جو اپنے بزرگوں کی توقعات پر پورا اترتا ہے۔
حضرت علامہ اقبال رحمۃ اللہ علیہ جو حکیم الامت بھی ہیں پوری دنیا ان کی عظمت کو سلام کرتی ہے ان کے اشعار جو دیوان کی صورت میں موجود ہیں ، اخلاق حسنہ پیدا کرنے میں ایک اہم رول ادا کرتے ہیں۔ یہ اپنے ان اشعار کے ذریعے خوابید ہ قوم کو بیدار کرنے کی کوشش کرتے ہیں۔
طلباء کے بارے میں جونظریات ،خیالات، تصورات، دیگر سلف صالحین کے ہیں ان سے ملتے جلتے علامہ اقبال رحمۃ اللہ علیہ کے خیالات اور توقعات ہیں۔ طلباء کے اندر وُہ چیز جوان کی شخصیت کونکھارنے کے لیے اہم رول ادا کرتی ہے مطالعہ ہے، مطالعہ کا عادی طالب علم اپنے ہم مکتب ساتھیوں میں، اپنے ہم عمر دوستوں میں عزت کی نگاہ سے دیکھا جاتا ہے، کمرۂ جماعت میں وہ مطمئن اور پرسکون ہوتا ہے، کیونکہ جو اسباق اس نے پڑھنے ہوتے ہیں وہ اس کی نظر سے پہلے گزر چکے ہوتے ہیں اور ان کی تشریحات سے پہلے ہی اس کی آشنائی ہوتی ہے۔
دوسری اہم خصوصیت جو طالبعلم کے لیے انتہائی ناگزیر ہے وہ صفائی ہے اور صفائی تو ویسے ہی ایمان کا حصہ ہے، صفائی اور پاکیزگی کی موجودگی طالب علم میںفہم وفراست کے اضافہ کا سبب بنتی ہے نفیس طبع طالب علم دیگر طلباء کی نسبت مستعد اور چاک و چوبند رہے ہیں۔ ان کی صلاحیتیں...

Fasting Gastric Acidity Evidential Effect on Esophageal Mucosal Damage

Gastric substances that potentially increase the esophageal mucosal damage are: gastric acid, pepsin, bile salts, and pancreatic enzymes. From all of these substances, the highest potential for reflux damage is gastric acid. Although the main cause of clinical symptoms of GERD is acid reflux, it has been known that there are subgroups with typical reflux symptoms that do not provide sufficient response or not responsive to PPI treatment. Despite the improvement of esophagitis, there is no clinical improvements in reflux symptoms of 30% respondents. Therefore, this study was designed to determine fasting gastric acidity with endoscopic findings in patients with GERD. A comparative-analysis study, which determine the fasting gastric acidity from endoscopic findings in patients with GERD. Samples recruited using consecutives sampling technique and divided into groups of esophagitis and non-esophagitis reflux. A total of 40 samples involved in this study. The Mann-Whitney test, was used for analyzing the difference between fasting gastric acidity from endoscopic findings of esophagitis lesions in patient with GERD. The median value for fasting gastric acidity in the esophagitis reflux group was 1.88 (0.82-4.84), whereas the median value for fasting gastric acidity in the non-esophagitis reflux group was 2.49 (0.68-5.97). The Mann-Whitney test result was p=0.298 (p>0.05). This study shows that there is no significant difference of fasting gastric acidity from endoscopic findings between esophagitis and non esophagitis reflux groups in patients with gastroesophageal reflux disease (GERD). This study shows that esophagitis lesions are not affected by gastric acidity.

Synthesis and Characterization of Hyperbranched Polymers

The applications of macromolecules are widespread in the modern world and their utilities keep on increasing. Several significant developments in the field of polymeric materials engaged transfer of advantageous characteristics via control of polymer architecture. The interest in hyperbranched polymers (HBPs) stems from the ability to manipulate polymer composition to impart a particular set of traits. This basic research work on HBPs was driven by curiosity and charisma of these extremely elegant and intricate architectures. The present thesis aimed to fabricate HBPs in a one-pot method using new monomers synthesized in this work. All the newly synthesized monomers were subjected to FTIR, 1H, 13 C NMR spectroscopy and elemental analysis. The next goal was to utilize commercially available monomers in the facile synthesis to different families of HBPs. The reactions were stopped before gelation by the optimization of polymerization conditions. A three pronged strategy to HBP was pursued and in each specific strategy AB2, A2 + B3 and 2A2 + CBB′, the shell chemistry of the HBPs was employed to tailor desirable properties. Initially, a novel AB2 monomer, 6-hydroxy-2,4-bis(4′-nitrobenzamide)pyrimidine (NAL), was synthesized and successfully polymerized to hyperbranched polyamide-ethers (HBPAEs), which was subsequently end modified. Afterward, new trifunctional monomers, 1,3,5-tris(4''-hydroxyphenylcarbamoyl)benzene (THPCB), 1,3,5-tris(3'',4''- carboxyphenyl)benzene trianhydride (TAn), and 1,3,5-tris(4′- aminophenylcarbamoyl)benzene (TAPCB) were designed, synthesized and efficiently polymerized to hyperbranched polyamide-esters (HBPAE), hyperbranched polyester- imides (HBPEI) and hyperbranched polyamides (HBPAs) respectively, via the polymerization of A2 and B3 monomers without gelation. In these cases a dilute A2 solution was added slowly to a dilute B3 solution to prepare HB samples in the absence of gelation. A new 2A2 + CBB′ approach was undertaken where an A2C dimer was formed initially which can be considered as a new A2B type of monomer. Further reaction among A2C molecules resulted in the formation of hyperbranched polyamide-esters (HBPAEs) containing pyrimidine moieties. Complete structural 1 elucidation of the ensuing HBPs was carried out using FTIR, H and i 13 C NMR spectroscopic analyses. Additionally, all the prepared HBPs were characterized for qualitative solubility test, inherent viscosity, molar mass, thermal stability, glass transition temperature (Tg) and crystallinity. Structure-property correlations were established and it was observed that properties depended on end functionality. The degree of branching (DB) determined for HBPs based on the 2A2 + CBB′ approach was found to be >60 % and 41-56 % for the AB2 and A2 + B3 systems. Molar masses were determined using GPC which showed that the prepared HBPs had moderate Mw values. Thermal analyses for different HBPs systems showed that aliphatic HBPs were less thermally stable and had values of Tg lower than aromatic ones. HBPs contain a distinct multiplicity of peripheral functionalities which offer sites for additional chemical modification or as templates for non-covalent intermolecular interactions. Modification of the end groups in the prepared HBPs was carried out using different modifiers and complete modification was achieved proving that reactive terminal functionalities were easily accessible. The modified polymers displayed good solubility in different organic solvents. The properties of HB systems were compared with their linear analogues based on the same backbone structure. Accordingly, solution viscosity measurements exhibited that HBPs had lower solution viscosity, enhanced solubility and predominantly amorphous character compared to their linear analogues of comparable molar masses. Tg evaluation of HBP samples of different systems were carried out and showed that our HB systems demonstrated a lower Tg than their linear counterparts. Intermolecular hydrogen bonding between pyrimidine nitrogens and the amide NH groups of adjacent molecules provided the basis for material uniqueness. In addition, pyrimidine moieties played a vital role in producing outstanding thermal properties of HBPs; therefore, pyrimidine rings influenced the structural and material characteristics of these HBPs. Future prospects and potential applications of these HBPs are also envisaged.
