کوئی تو ابرِ مودّت، کوئی سحابِ کرم
کوئی تو ابرِ مودّت، کوئی سحابِ کرم
حضورؐ اب تو کھلے ہم پہ کوئی بابِ کرم
مرے نبیؐ کا وُہ دربارِ محتشم ہے جہاں
نہ کوئی حد ہے کرم کی نہ کچھ حسابِ کرم
ہماری آنکھوں میں کنکر دکھوں کے چبھتے ہیں
علیؓ کا واسطہ! بخشیں ہمیں لعابِ کرم
وُہ جس کو پڑھ کے مؤ لف قلوب ہوتے ہیں
اب اُترے ہم پہ بھی صفّہ کا وُہ نصابِ کرم
کہ اب تو تشنہ لبی سے دماغ جلتا ہے
سو کوئی ابر کا چھینٹا کہیں سے آبِ کرم
دلوں میں تیرگی تعبیر کی مسلّط ہے
ہمیں عطا ہو کوئی روشنیِ خوابِ کرم
وفورِ رحمتِ عالم مآبؐ اتنا ہے
عجب نہیں کہ میں لا ہی سکوں نہ تابِ کرم
سلام و ذکر سے ایماں کی آبیاری کروں
کھلے گا نخلِ تمنا پہ یوں گلابِ کرم
حروفِ رحمت و رافت میں چوم لوں عابدؔ
کُھلی ہوئی ہے مرے سامنے کتابِ کرم
Parental Factors Affecting Student's Self-Concept and Academic Performance Amid Modular Distance Learning
Nelda B. Caasi Palawan National School, Puerto Princesa City, Palawan, Philippines Parental factors impact students’ self-concept and academic performance during the pandemic. Thus, this study determined the students’ self-concept and academic performance and the parental factors related to it. The research design was descriptive-correlational, and 500 nonrandom college students in West Philippines participated in the study. Researcher-made instruments were used, which were subjected to reliability and validity evaluation. Data were collected online from June 2021 to July 2022 and were analyzed using descriptive (frequency counts and percentage) and inferential statistics (Spearman correlation). Results revealed a positive self-concept and satisfactory academic performance among the students. Besides, parental factors such as educational attainment and school/classroom involvement are significantly related to self-concept and academic performance. Further, self-concept is significantly associated with academic performance. This shows that some parental factors are vital in developing the student’s self-beliefs and supporting their studies and academic endeavors amid the COVID-19 pandemic. Future studies may consider more factors related to academic achievement and self-concept. Other researchers may find the mediation or moderation effect of self-concept between parental factors and students’ scholastic achievement.Synthesis and Characterization of New Polyamides, Poly Amide-Imide S, Polyimides and Polyurethanes Bearing Thiourea Moieties
This thesis primarily addresses the systematic modification of polyamides, poly(amide- imide)s, polyimides and polyurethanes to yield high performance poly(thiourea-amide)s, poly(thiourea-amide-imide)s, imide)s, poly(thiourea-ether-imide)s, poly(urethane-thiourea)s, poly(phenylthiourea-azomethine- poly(urethane-thiourea-imide)s and poly(urethane- azomethine-thiourea)s. The foremost goal of current research is the structural modification of polymers exploiting the synthetic chemistry to attain excellent solubility via slightly disrupting polymer chain regularity and packing. Various synthetic schemes were developed for the inclusion of thiourea moieties along with other desired linkages in these polymers. The designed monomers (dinitro, diamines, dicarboxylic acids, diacid chlorides, diols and diisocyanates) bearing pre-formed linkages were then synthesized and employed for the preparation of novel thiourea-based polymeric materials. The incorporation of different functional groups provides an opportunity to control certain physical properties such as solvent miscibility, η inh , crystallinity, molecular weight, thermal stability and flame retardancy of the resulting polymers. The effect of thiourea and other functional groups on the properties of newly synthesized polymers were scrutinized together with their structure-property relationship. Major tools utilized for the examination of polymer properties are FTIR, 1 H NMR, solubility, viscometry, GPC, TGA, DSC and XRD. Novel thiourea-based polymers demonstrated outstanding thermal stability without deteriorating their organosolubility or processability. Another objective of the work was to evaluate the expedient applications and potential relevance of these valuable high-performance materials for advanced technologies. The processable poly(thiourea-amide)s, poly(thiourea- amide-imide)s, poly(thiourea-ether-imide)s and poly(urethane-azomethine-thiourea)s were found to have superior thermal stability as well as non-flammability. Poly(phenylthiourea-azomethine- imide)s having C=S and –C=N– moieties can act as imminent contenders to fabricate certain electrically conducting materials. Poly(thiourea-amide)s, in addition to the excellent solubility and thermal resistance, can be employed as solid extracting phases for the elimination of environmentally toxic metal ions from aqueous media. Prior to this effort, reported in peer- reviewed journals, synthesis of high temperature polymers bearing C=S entity was an unexplored area. Easy processability, high molar mass, heat and flame stability, electrical conductivity, etc, depict their high adaptability in future, rendering them backbone materials in polymer science.Journals by Discipline
