مولانا سعیداحمد اکبرآبادی
اس سے زیادہ دلدوز خبر،مفتی عتیق الرحمن ؒ کے وصال کے بعد ندوۃ المصنفین ماہنامہ برہان کے لیے کوئی دوسری نہیں کہ ۲۴؍ مئی مولانا سعید اکبرآبادی کاکراچی میں انتقال ہوگیا۔اِنَّا لِلّٰہِ وَاِنَّا اِلَیْہِ رَاجِعُوْنَ ْ
مولانا سعید احمد اکبرآبادی کی رحلت،علمی، ادبی، اوردینی، اور صحافتی دنیا کا ایک ایسا نقصان ہے جس کی تلافی کی کوئی صورت بظاہر موجود نہیں ہے وہ ان نادر شخصیتوں میں سے جن کے اندر قدیم اورجدید علوم جمع ہوجاتے ہیں اور وہ زمانہ کو اپنی خداداد ذہانت اور طبائع کی روشنی سے منّور کرنے کاایسا عظیم الشان کام انجام دیتے ہیں، جوقدیم علوم کے ماہرین اور جدید علوم کے علمبردار وں سے الگ الگ صورت میں ممکن نہیں۔ مولانا سعید احمد اکبرآبادی ایک طرف علامہ انور شاہ کشمیریؒ کے ذریعہ اورواسطے سے ،اس سلسلۃ الذہب سے منسلک نظرآتے ہیں،جواسرار علوم نبوت کے محرموں اورفقہ وحدیث کے بالغ نظر عالموں، اسلامی شرع اوردینی کمالات کے حامل شخصیتوں کاایک ایسا قافلہ ہے، جس نے دینی علوم کوتحقیقی صلاحیتوں کے قالب میں ڈھال کر ہرزمانہ اور ہرعہد کے مطابق بنانے اور اس کی رہنمایانہ استعدادقائم ر کھنے میں ناقابلِ فراموش حصّہ لیا۔ دوسری طرف سے وہ جدید علوم سے پوری طرح واقف، اور دنیا میں سائنسی اورصنعتی اورمعاشی انقلابات کے اثرات ونتائج سے مکمل طورپر باخبر اور نئے زمانے کے تقاضوں کاپورا شعور رکھنے والے ایک دانشور تھے، جوقدیم علوم کی آب و تاب،مذہبی روایات کے تقدس کی برقراری اور اصول واحکام دین کی پاسداری بلکہ نگہبانی کافرض آدھی صدی سے بھی زیادہ مدّت تک انجام دیتے رہے۔وہ ایک طرف مفتی عتیق الرحمن عثمانی ؒ،مولانا حفظ الرحمن سیوہاروی ؒ، مولانامحمد یوسف بنوری ؒ، مفتی محمد شفیع دیوبندیؒ،قاضی زین العابدین سجاد میرٹھی(تعالیٰ اﷲ عمرہٗ) مولانا احمدعلی لاہوریؒ،اورمولانا قاری محمد طےّب قاسمیؒ ،جیسے نابغۃ العصراور فقید المثال ماہرین علوم شریعت اور...

MEWASPADAI VIRUS LGBT PADA PENDIDIKAN ANAK

LGBT (Lesbian, Gay, Bisexual and Transgender) is a frightening epidemic of society, especially in Indonesia. The epidemic also infects most children and adolescents. So as educators, both parents and teachers should pay particular attention  to the symptoms that cause virus LGBT in the community, especially in children's education. Because it is against the nature, norms, customs, religion and morals of humanity. Moreover, LGBT's behavior is not a disease transmitted through genes or disorders, but more to the consequences mistakes and erros of children’s education.

Synthesis and Characterization of Nanoparticles Added Cutl-Based Superconductors

Low anisotropic (Cu 0.5 Tl 0.5 )Ba 2 Ca 2 Cu 3 O 10-δ (CuTl-1223) phase of Cu 1-x Tl x Ba 2 Ca 2 Cu 3 O 10- δ [CuTl-12(n-1)n]; n=1, 2, 3, ... high temperature superconducting (HTSC) family was synthesized by solid-state reaction method. Nanoparticles (NPs) were prepared separately by different techniques (i.e. co-precipitation, sol-gel, and colloidal solution methods). Different kinds and sizes of NPs such as non-magnetic metallic (Ag, Au), non-magnetic metallic oxide (Al 2 O 3 ) and magnetic ferrite (CoFe 2 O 4 ) were added with different wt.% during the final sintering process of CuTl-1223 superconducting matrix to get the required (NPs) x /CuTl-1223 nanoparticles-superconducting composites. These composites were characterized by different experimental techniques such as x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive x-ray (EDX) spectroscopy, resistivity versus temperature measurements, critical current density (J c ) measurements, magnetic ac-susceptibility measurements, Fourier transform infrared (FTIR) spectroscopy etc. The experimental data were analyzed by different well established theoretical models such as Aslamazov-Larkin (AL), Lawerence-Doniach (LD) and Maki-Thompson (MT) models. It was observed that tetragonal structure and stoichiometry of the host CuTl-1223 superconducting phase remained unaltered after the addition of these NPs, which indicates about the occupancy of these NPs at the inter-granular spaces. Non-magnetic metallic NPs (Ag, Au) have improved the superconducting transport properties (T c , J c , etc) up to certain optimum concentration of these NPs in CuTl-1223 matrix. The improvement in the superconducting properties can be attributed to an increase in the inter-grains connectivity by healing up the inter-grains voids and pores after the addition of these NPs. The improved inter-grains connections can facilitate the carriers transport processes across the inter-crystallite sites due to their metallic nature. But the superconducting volume fraction starts to be decreased after certain optimum inclusion level of these non-magnetic non-superconducting metallic NPs, which causes the suppression of superconductivity parameters. The effects of highly coercive cobalt ferrite (CoFe 2 O 4 ) nanoparticles addition on superconducting properties of CuTl-1223 matrix were also explored. The magnetic behavior of CoFe 2 O 4 nanoparticles was determined by MH-loops with the help of superconducting quantum interference device (SQUID). The resistivity versus temperature measurements showed an increase in T c (0), which could be most probably due to improvement of weak-links by the addition of these nanoparticles. The increase of mass density with xxviincreasing content of these NPs can also be an evidence of filling up the voids in the matrix. But the addition of these NPs beyond an optimum level caused the agglomeration and produced additional stresses in material and suppressed the superconductivity. We observed non- monotonic variation of superconducting properties after the inclusion of nano-Al 2 O 3 particles, which can be associated with inhomogeneous distribution of these NPs at the grain-boundaries in CuTl-1223 matrix. But overall suppression of superconducting properties was attributed to a pair-breaking mechanism caused by reflection/scattering of carriers across these insulating nano- Al 2 O 3 particles present at the grain-boundaries of the host CuTl-1223 matrix. The presence of Al 2 O 3 nanoparticles at the grain-boundaries possibly reduced the number of flux pinning centers, which were present in the form of weak-links in pure CuTl-1223 superconducting matrix. The suppression of activation energy {U (eV)} may be due to weak flux pinning in the nano-Al 2 O 3 particles added samples. The superconducting microscopic parameters (i.e. zero temperature coherence length along c-axis {xc (0)}, inter-layer coupling (J), inter-grain coupling (a) etc.) deduced from fluctuation induced conductivity (FIC) analysis with the help of above mentioned theoretical models explained the experimental findings very well. For example, the increase in the values of inter-grain coupling (a) deduced from FIC analysis is a theoretical evidence of improved inter-grain coupling in the host CuTl-1223 matrix with the increased contents of these nanoparticles. We also calculated the activation energy {U (eV)} of (NPs) x /CuTl-1223 nanoparticles-superconducting composites. The increase in T c (0), J c , U (eV) etc and decrease in normal state resistivity {ρ 300 K (Ω-cm)} were observed after the addition Ag, Au and CoFe 2 O 4 NPs in CuTl-1223 superconducting phase. The suppression of superconducting properties (i.e. T c (0), J c , U (eV) etc) after the addition of Al 2 O 3 nanoparticles in host CuTl-1233 superconducting matrix was observed.
