النورسي ومعالجته النقدية الايجابية البناءة للقضايا

From the very first day, the scholars of the Ummah, Particularly from the time of Im฀m Sh฀f฀ movements of Islamic thought originated, which affected not only the Arabic world but the whole Islamic world. There had been movements of severe revenge and bloodshed and a lot of people were killed. Im฀m Nawras฀ is one of those unique people who served the Islamic thought from such dangerous storms. Day and night he made selfless efforts. He criticized the falsehood and injustice. The period of Im฀m Nawras฀ was plagued with severe gales of argumentations. This became the cause of Invitational, reformative and renewing movement of Im฀m Nawras฀. It faced the western and European attacks which appeared after Industrial and ideological revolutions of Europe. Before starting the movement, he did deep study of current affairs, Islamic thought and history. He studied the reasons due to which chaos of Islamic thought began. It was necessary to study all the situations and to fight with the contemporary Atheistic thought and wipe out its effects. So this article discusses intellectual contributions of Im฀m Nawras฀. He is great in handling the critical situation, and his conservative positive criticism is excellent. He is one of those luckiest persons who survived and got a chance to serve humanity. He was unique in handling intellectual issues away from dialectical demagoguery. Im฀m Nawras฀ really worked great for Islam. His principles regarding intellectual positive criticism, his philosophical thoughts, his criticism on mystic issues are presented here in this article. It is important to study and analyze Nawras฀ ’s amazing ability and his critical positive approach and treatment of constructive issues away from the ego.

Infield Superconducting Transport Properties of Magnetic Nanostructures-Cutl-1223 Composites

(M) x -CuTl-1223; M = Ni, Co, CoFe 2 O 4 , Cr, Al 2 O 3 , nanoparticles-superconductor composites were synthesized by solid-state reaction (ceramic method) and their infield (magnetic) superconducting properties were investigated. Structural, morphological and compositional analysis of these composites were carried by using X-rays diffraction (XRD) analysis, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX), respectively. The infield transport measurements were carried out by resistance versus temperature (RT) measurements with small current ( ˷ 10 μA) by using four-probe technique with the help of physical properties measurement system (PPMS). Broadening in superconducting transition region was observed with increasing the external applied magnetic field (H) in all the samples, which was attributed to thermally activated flux flow (TAFF). Flux pinning strength was calculated by using TAFF model. The field dependent flux flow activation energy {U o (H)} of CuTl-1223 superconducting matrix was increased with addition of ferri-magnetic (CoFe 2 O 4 ) and antiferromagnetic (Cr) nanoparticles up to certain optimum level of concentration. The transition width (ΔT) of CuTl-1223 phase was decreased after addition of these nanoparticles. The enhancement in U o (H) and reduction in ΔT show improvement in flux pinning ability of CuTl- 1223 matrix with addition of CoFe 2 O 4 and Cr nanoparticles. The flux pinning strength of CuTl- 1223 phase was decreased with addition of ferromagnetic (Ni and Co) and non-magnetic (Al 2 O 3 ) nanoparticles. It was observed that U o (H) decreases and ΔT increases with the addition of these nanoparticles. The suppression in U o (H) with increasing magnetic field obeys the power law (U o = β H - a ) . The value of ‘a’ corresponds to the suppression rate of U o (H) with H. The decrease in ‘a’ with the addition of Cr, Co, and Al 2 O 3 nanoparticles showed that the decreasing rate of activation energy with increasing H is lowered with addition of these nanoparticles. Thus although the addition of Co and Al 2 O 3 in CuTl-1223 matrix decreases its flux pinning but their addition has lowered the suppression rate of U o (H) with H, which shows that the inclusion of these nanoparticles can make CuTl-1223 superconductor suitable for high field applications. In case of addition of CoFe 2 O 4 and Ni nanoparticles in CuTl-1223 superconductor, value of ‘a’ increases which indicates that lowering rate of activation energy increases with the rise in H. The transition width (ΔT) was increased with the rise in H, which shows TAFF takes place in the samples with small current. It was observed that broadening in ΔT with ‘H’ obeys a power law (ΔT = ΔT o + CH n ) where ΔT o is the transition width in absence of applied field.
