مولانا محمد ابراہیم بلیاوی
ابھی مولانا شاہ وصی اﷲ صاحبؒ کا غم تازہ تھا کہ ایک اور بزرگ ہستی کا سایہ اٹھ گیا، رمضان المبارک کے آخری عشرہ میں مولانا محمد ابراہیم صاحب بلیاوی صدر مدرس دارالعلوم دیوبند نے وفات پائی مرحوم اس دور کے نامور عالم دین اور صاحب تقویٰ بزرگ تھے تقریباً نصف صدی تک دینی علوم کے درس کی خدمت انجام دی اور ان کے چشمۂ فیض سے ہزاروں تشنگان علم سیراب ہوئے، ان کی وفات سے علم و عمل، درس و تدریس اور تدین و تقویٰ کی ایک بڑی یادگار مٹ گئی اﷲ تعالیٰ ان کے مدارج بلند فرمائے۔

Education is the development of the different aspects of human being like psychological, social and physical development etc. It is not only the provision of information but it is for the sake of guidance of students to make them beneficial human beings. A teacher inculcates good habits in students and tries to reduce or terminate bad habits in them. Therefore, the responsibility of teacher is to guide the students about good and bad along with improving their academics. But while doing so, the teacher should avoid the ways which can be harmful for the students. Therefore he (the teacher) should know how to guide the students and stop them from wrong doings. At what time what technique, he should adopt that can give benefits to students? He should be aware of the student’s psychology, their age and their abilities. Sometimes punishment is very much necessary for students to make them realize not to commit anything like this again. At this critical moment what can help the student and teacher? The Holy Prophet Muhammad (SAW), being a perfect teacher guided the Umma in this aspect. He used many skills as a teacher and taught his followers, how to guide their children and pupils. Many times the prophets would use to advise his followers on anywrong doing and that is why none of the followers repeated the same mistake. It is very important to follow the teachings of the Holy Prophet in aspect. This research paper discusses the way of handling the students in different situations.
Chlorpyrifos (CFS) is one of the most common insecticides found in freshwater ecosystems and
has been detected in agricultural and fishery products worldwide. Acute toxicity assessment was
carried out by24hour LC50 of chlorpyrifos to freshwater fish Oreochromis niloticus. The value
for 24hour LC50 was determined as 37.93 ? 20.02?g/L. The experiment was carried to measure
the effects of different concentrations of chlorpyrifos (CFS) on O. niloticus through the
evaluation of biochemical and hematological parameters in addition to histological examination.
One hundred and twenty O. niloticus were randomly distributed into four groups in triplicates
containing ten fish per aquarium. The first group served as a GC (control group), which is the
non-treated group. The second group G1 was exposed to 1/11
of 24hour LC50. The third groupG2 was exposed to 1/7th
of 24hour LC50. While the fourth group G3 was exposed to1/3
rd of
24hour LC50.The exposure was for 14 days in all treated groups. Fish exposed to CFS showed
histological alterations as compared to control groups. Alterations were more prominent in high
dose group G3. Congestion, necrosis and hemorrhage in gills, degeneration in muscles and
intestine were noticed. In hematological assessment, significant increase in WBCs, LYMP,MCH
and MCV with the increase in dose was noticed while decrease in RBCs, HGB, HCT and MCHC
was observed with increase in dose as compared to control. Significant increase in AST and ALT
was observed.This study provides significant perceptions about the acute toxic effects of CFS on
fish and show potential to be used as biomarkers in further toxicological evaluation studies
