عظیم ذات ہے اُس کی، بزرگ و برتر ہے (حمد)

حمدباری تعالیٰ

عظیم ذات ہے اُس کی بزرگ و برتر ہے
نہ کوئی ثانی ہی اُس کا نہ کوئی ہمسر ہے

جو بحر اُس کا ہے سارا تو اُس کا ہی بر ہے
جو خشک اُس کا ہے سارا تو اُس کا ہی تر ہے

وہی تو ہے جو ہے ذات و صفات میں یکتا
ہر ایک رنگ میں بے مثل وہ سراسر ہے

ہیں دو جہاں پہ عطائیں تمام تر اُس کی
وہ بے عدیل سخی ، بے مثال داور ہے

یہ اور بات کہ ہے لا مکاں مکاں اُس کا
مگر جو ہے دلِ مومن وہ اس کا ہی گھر ہے

Factors Related to the Development of Children's Motoric in Integrated Service Post

Motor development is a process of growing and development of motion ability of children's development conditions with the nerve and brain development of children so every simple movement is the results of complex interaction patterns of various and optimized particular systems. Motor development is connected with the growth process of motoric associated with knowledge, family income and attitudes of moms. The type of research used is observational research with the "cross sectional study" approach, to know the factors related to motor development of motorcycle of body in the integrated service post of Sawi Massamaturu village, popular district. Research results show that of the large 30 sample estimates, 14 children with normal motor development and 6 children that the motor development is disturbed. Conclusion in this research a significant relationship between knowledge, and attitude with the motoric development of family income not significant the development of children motoric

Study of Zinc Ferrite Containing Ferrimagnetic Bioactive Glass Ceramics for the Hyperthermia Treatment of Cancer

Ferrimagnetic bioactive glass ceramics are expected to be potential candidates for the hyperthermia treatment of cancer. When placed in an alternating magnetic field of high frequency, these materials generate heat energy by hysteresis and eddy current losses. Tumor cells usually perish around 43 °C due to the poorly developed nervous and circulatory system whereas healthy body cells remain unaffected at this temperature. Such materials should have the adequate ability to bond with the tissues (bioactivity). Much work has been done on Fe 3 O 4 containing glass ceramics for this purpose but present work is the first ever detailed study of its kind on ZnFe 2 O 4 containing ferrimagnetic bioactive glass ceramics for the hyperthermia treatment of cancer. Glass ceramics of the composition (%wt) xZnO • 25Fe 2 O 3 • (40 -x)SiO 2 • 25CaO • 7P 2 O 5 • 3Na 2 O were prepared by melt-quench method and subsequent sintering at 1100 °C. After sintering the materials were quenched to about -10 °C to cause ferrimagnetism by preserving the high temperature state of mixed spinels, i.e., random distribution of cations at tetrahedral (A) and octahedral (B) sites of the spinel lattice. Magnetic properties of ferrimagnetic materials were further enhanced by cooling the materials in an aligning magnetic field to cause anisotropy. XRD was used to study the crystalline phases in the materials. Magnetic properties of the materials were studied using VSM. The sample X10 (having 10% ZnO) exhibited the highest hysteresis area. Calorimetric properties were studied by placing the materials in a magnetic induction furnace. The sample X10 exhibited the best magnetic heat generation due to its highest hysteresis losses. Anisotropic materials showed better magnetic and calorimetric properties than the non-aligned materials. Materials were immersed in simulated body fluid (SBF) for 3 weeks to study the bioactivity. In Vitro characterization was carried out using XRD, FTIR, SEM, EDS, AAS & pH meter. The results confirmed that all samples were bioactive as layers of biological hydroxycarbonate apatite (HCA) appeared after 3 weeks. Sample X10 exhibited adequate bioactivity. Due to balanced calorimetric & biological properties, sample X10 was considered the potential material of choice to be used for the hyperthermia treatment of cancer as well as for re-enforcement of the damaged bones.
