معاشرے کی تعمیر وترقی میں طلباء کا کردار
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز سامعین اور میرے ہم مکتب شاہینو!آج مجھے جس موضوع پر لب کشائی کرنی ہے وہ ہے:’’معاشرے کی تعمیر وترقی میں طلباء کا کردار ‘‘
جنابِ صدر!
طالب علم معاشرے کا ایک اہم جزو ہے، ایک اہم حصہ ہے، معاشرے کی تسبیح کا ایک اہم دانہ ہے، ایک اہم شمارہے، طالب علم کا وجود گھر کے لیے، خاندان کے لیے، معاشرے کے لیے، ملک وقوم کے لیے ریڑھ کی ہڈی کی حیثیت رکھتا ہے۔ وہ معاشرہ جس میں طالب علم کا کوئی کردار نہ ہو وہ حقیقت میں معاشرہ کہلانے کا حق دار نہیں ہے۔
صاحبِ صدر!
ایک ہونہار طالب علم جب علمی درسگاہ کے زیور سے مزیّن اور مرصعّ ہو کر خانگی ، معاشرتی، سیاسی اور قومی ماحول میں قدم رکھتا ہے تو اس کا وجود پورے ماحول کو متاثر کرتا ہے، اس کی گفتگو، اس کی نشست و برخاست ، اس کا قیام وقعود معیاری ہوتا ہے، اس کا اندازِ جہاں بانی منفرد اور یکتا ہوتا ہے، اس نے دورانِ تدریس صحت مند اور مفید نصاب کے اوراق اسود کی ورق گردانی کی ہوتی ہے۔
جنابِ صدر!
اس نے اگر منافقت کا باب پڑھا ہوتا ہے تو ریاکاری اور منافقت سے دور رہ کراپنی زندگی گزارتا ہے ،گل سر سبنر کی طرح مضافاتی علاقے کو معطر رکھتا ہے، جو تعلیمی ادارے میں پڑھتا ہے اس پر من وعن عمل کرتا ہے، اس کی زندگی عوام النّاس کے لیے ایک نعمت غیر مترقبہ ہوتی ہے۔
معزز سامعین!
ایک ذی فہم و فراست اور ذی شعور طالب علم ،علم و دانش کے نشتر سے معاشرے کے وجود سے جہالت، نفرت، بغض، حسد، ریا کاری ،نمود ونمائش، اقرباء پروری...
Islam is a comprehensive code of conduct which encompasses to each sphere of human life. This also owns and endorses those manmade rules which serve the cause of humanity and not entering to its fundamentals. Adherence to Pakistani Traffic rules also falls under the preview of the same doctrine. It is very pertinent to note here, that the same traffic rules such as fastening of seat built, proper use of indicators, speed control etc. Have been devised to ensure the safety which starts from a pedestrian and ends up to a rider of any vehicle class. Any violation of traffic rules is an indirect breech of divine discipline imposed by Allah the Almighty. If the violation costs any damage, injury or fatal accident, this will directly be dealt under the principles set by Islam. This study aims at highlighting the significance of adherence to traffic rules which is directly linked to the ground safety. This ultimately serves the main purpose of saving any precious human life. If the same is ensured, no doubt the purpose of the holy verse would be fulfilled
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.
