مظلوم بہن کی فریاد

مظلوم بہن کی فریاد

’’اگر مجھے پتہ ہوتا میری حکومت گرانے کے لیے میرے بھائی کو قتل کیا جائے گا ۔تو میں کبھی بھی پرائم منسٹر ہائوس کے لیے نہ لڑتی ۔‘‘

یہ کوئی سیاسی بیان نہیں ایک مظلوم بہن کی اپنے بھائی کے قتل پہ فریاد ہے ۔کنیزِ کر بلا کا یزیدیت کے خلاف مقدمہ ہے ۔مظلومیت کا نوحہ ہے ۔بھٹو خاندان پہ ہو نے والے مظالم ہمار ی تاریخ پہ بد نما داغ ہیں اور اس سے بھی بڑی بے ضمیری یہ ہے کہ قاتل انہیں قتل کرنے کے بعد قتل کا الزام بھی انہی پہ لگاتے رہے ۔

 

وہ دریا دیس سمندر تھی

جو تیرے میرے اندر تھی

وہ سوہنی مٹی سندھڑی کی

وہ لڑکی لال قلندر تھی

یادگارِ کار ساز

ہماری خاک سے خوشبو وطن کی آئے گی

ہمارا خون اس مٹی کے رنگ میں شامل ہے

 

THE TEACHERS AND STUDENTS PERCEPTION ON ENGLISH TEXTBOOK WHEN ENGLISH RINGS THE BELL

Abstract The purpose of this study is to compare the student's and teacher’s perceptions about their current English textbook they used. This study categorized as a descriptive qualitative study. The population of VIII grade students (45 students) of junior high school was involved in this study and an English teacher of them too. The questionnaire and semi-structured interview were used as the instrument of this research. Besides, the guideline of the interview and questionnaire was from [1]Cunningsworth's (1995) theory which is explained about the book evaluation. The data were analyzed through Google form percentage presentation for the questionnaire while transcription, coding was used for the interview section. The result showed, 75% of students believed that the book they used has good quality. While the rest 25% felt it did not fulfill their expectation and need. Besides, the teachers’ perception supports it with some of the books’ part lacks organization and employed too many vocabularies. Whereas the students felt their current level was not suitable with the teachers’ beliefs, but the teacher believed that it was appropriate with the students’ level. So, there were few different perceptions between them.  However, the teacher believed that her role in helping students with textbook usage could help the main point of students’ need due to the teacher has lack of knowledge and awareness to do coursebook evaluation. Therefore, further research needs to be done to make this study more comprehensive.    

Aspartic Acid Racemization - a Precise Tool in Forensic Age Estimation in Human Dentin

BACKGROUND: Age estimation is a major concern in Forensic Medicine for its prime importance in legal, socioeconomic and other global issues like bomb explosions, mass migration & mass disasters both in alive or cadavers. Classical methods based on morphological, radiological or histological methods are being used. The precision and reliability of these methods have margin of error of ± 10 years. There is a need for development of a biological tool at molecular level. Amino acid racemization in dentin is found to be a precise model for age estimation with margin of error within ± 3 years. OBJECTIVES: Current study was designed to determine the correlation of coefficient of aspartic acid racemization (KR) with reference to age. Secondary objective of this study was calculation of margin of error between chronological age & calculated age by racemization method. Third objective was calculation of correlation of gender, socioeconomic status & different age categories with KR (Coefficient of racemization). MATERIALS AND METHODS: This study was conducted in dental outpatients‘ clinics at Ziauddin Hospital, Karachi. The duration of study comprised of two years 2011-2013. It was a Cross sectional study and sampling technique was convenient sampling Sample size calculated was 116 subjects. ERC approval was taken. An oral expressed consent of patients was taken. Preliminary data including name, gender, chronological age (Y-M-D), socio-economic status, educational status, monthly income, occupation and any other factors affecting oral health was entered into a specially designed performa for this study. High-Pressure Liquid Chromatography was performed on each sample to quantify the L and D forms of aspartic acid in dentin. RESULTS: Total sample size was 116 subjects, which were divided into two groups – Test group of 85 subjects of known age group and Validation group of 31 subjects whose age were kept unknown to the researcher. 85 teeth samples of known age group (test group) were analyzed and D/L ratio of aspartic acid was estimated by HPLC technique. Regression line was derived from scatter plot graph and least square method was used to calculate the regression equation. The coefficient of racemization (KR) for each tooth was calculated using the formula KR = In [(1+D/L)/ (1- D/L). For checking whether regression equation would correctly predict the age, the proposed formula was applied for validation group of 31 teeth and then difference between actual age and predicted age of 31 samples were calculated. Co-efficient of determination was found to be 0.96, which show that regression equation for estimating age was 96% correct. There was a very strong positive correlation (0.98) observed between actual ages and co-efficient of racemization, which indicates that as age increases co-efficient of racemization increases. CONCLUSION: As the correlation coefficient proved to be strongly positive, it suggests racemization of human dentine could be used as a precise method for estimation of chronological age in living and in dead. The error of margin between calculated and chronological age was ± 2.44 years in 116 subjects. PValue was significant among different age groups. KR coefficient has significant correlation with age rather than gender and socioeconomic status. HPLC is a reliable technique to estimate the coefficient of racemization because it is highly reproducible, cost-effective and convenient. However there is a need for extensive research towards standardization of the method to enable quality assurance within and between laboratories.
