ایمان سے وہ شخص تو ایماں کی طرح ہے

ایمان سے وہ شخص تو ایماں کی طرح ہے
وہ دشمن جاں مجھ کو مری جاں کی طرح ہے

ہر دن ہے تری صورتِ پُرنور کی صورت
ہر رات تری زلفِ پریشاں کی طرح ہے

عزت میں بہت کرتا ہوں ہر ایک ہی ماں کی
ہر ماں مجھے لگتا ہے مری ماں کی طرح ہے

اک تیری جھلک باعثِ تسکینِ دل و جاں
دیدار ترا درد کے درماں کی طرح ہے

ساون کی طرح میری ہے آنکھوں کا برسنا
اور جلنا مرے دل کا، چراغاں کی طرح ہے

ہر شب ہے مری رنج کی روداد کے جیسی
ہر روز مرا درد کے عنواں کی طرح ہے

جس دن سے مرے دیس کو تم چھوڑ گئے ہو
اُس دن سے مرا دیس بیاباں کی طرح ہے

دستورِ زباں بندی یہاں جب سے ہے نافذ
یہ شہر مرا شہرِ خموشاں کی طرح ہے

ہے وصل ترا گلشن و گلزار کی مانند
اور ہجر ترا خارِ مغیلاں کی طرح ہے

اے قیس! ترا چاکِ گریبان جو دیکھا
یہ چاک مرے چاکِ گریباں کی طرح ہے

ہر صبح، مری صبحِ قفس جیسی ہے تائبؔ
ہر شام مری شامِ غریباں کی طرح ہے

Assessment of Dietary Behavior of Children Aged between 3-12 Years Suffering from Thalassemia Visiting Tertiary Care Hospitals, Lahore Dietary behavior of Thalassemia children

Thalassemia is a hereditary blood disorder passed down through families in which the body makes hemoglobin in an abnormal form. Nutritional deficiencies in thalassemia children results in anemia and other medical complications. Objective: To assess dietary behavior of children aged between 3-12 years suffering from thalassemia. Methods: A cross-sectional study was carried out in the outdoor patient department of thalassemia at Sir Ganga Ram Hospital, Lahore for 4 months.100 patients were selected through non probability sampling technique. Data was tabulated and analyzed by SPSS version 21.0. Results: Thalassemia was more prevalent in the age group of 8-12 years. Nutritional deficiencies in thalassemia patients caused anemia as it was evident from results that 74% of thalassemic children had pale skin. As far as dietary intake was concerned only 4% of thalassemia children were consuming meat and meat products.58% of thalassemia children consumed milk on daily basis. Only 8% took green leafy vegetables on daily basis as it contains high amount of iron. Micro nutrient deficiencies as vitamin A, C were common among thalassemia patients as only 30% were consuming fruits on daily basis. Conclusions: Most of the thalassemiacchildren were found to be malnourished due to inadequate dietary intake. The caregivers and parents should be counseled to create awareness

Synthesis and Charaterization of Polyurethane Composite Materials Derived from Hydroxy Terminated Polyepichlorohydrins

Hydroxy terminated polyepichlorohydrins (PECH) of different molecular weights were synthesized using a novel catalyst and co-catalyst combinations. Different polymerization conditions like temperature, time and monomer addition rates exhibited pronounced effect on the molecular weight, polydispersity and functionality of the products. After optimization of the conditions, polyepichlorohydrins of three different molecular weights i.e., 1045, 2497 and 3521 daltons were selected for the preparation of their polyurethane elastomers (PUE). The DSC studies of the polyol displayed linear increase in glass transition temperature (Tg) with the increase in its molecular weight (-35.6 to -28.3 oC). In second part of the present study two series of polyurethane elastomers were prepared by prepolymer method from polyepichlorohydrins (polyols) of three different molecular weights, aromatic (TDI) and cycloaliphatic (IPDI) diisocyanates and three chain extenders (1,4-butadiol, 1,6-hexanediol and cyclohexanedimethanol). The structural elucidation of PECH and its elastomers was carried out by FT-IR and NMR spectroscopic techniques. The change in molecular weight (polyol), type of diisocyanate, nature of chain extender and amount of chain extenders engendered significant effect on the surface morphology and thermo-mechanical properties of the resulting PUEs. Aromatic diisocyanate based elastomer (P25TDIDM10) exhibited optimum UTS (8.11 MPa) and elongation at break (511.7%) whereas cycloaliphatic diisocyanate elastomer (P10IPDIDM10) showed 8.58 MPa UTS and elongation at break (511.7%). All the polyurethane elastomers were stable up to 200 °C and were degraded without melting to constant mass above 450 °C. Tg of TDI based PUE was increased to -16 oC while in IPDI series it was further shifted to 7.98 oC. In the third part of this research work, selective polyurethane elastomer P10IPDIDM10 was used, due to its superior properties, as a matrix for the synthesis of polymer based composites. Graphite, aluminium flakes and aluminium powder were used in different proportions (5-15%) as fillers in the polymer matrix composites. Incorporation of fillers enhanced the UTS with corresponding decrease in elongation at break, whereas in case of graphite, electrical properties of the composite were also improved. The present study revealed that the synthesized PUEs and composites were found promising candidates for various advanced applications.
