ڈاکٹر یعقوب صروف
اڈیٹر المقتطف کی وفات، علمی حلقہ میں یہ خبر نہایت افسوس کے ساتھ سنی جائے گی کہ مصر کے مشہور علمی، صنعتی، زراعتی اور فلسفیانہ رسالہ المقتطف کے دوسرے اڈیٹر ڈاکٹر یعقوب صروف نے بھی جولائی ۱۹۲۷ء کو وفات پائی۔ یہ وہ شامی اہل قلم ہے جس نے عربی ممالک میں سب سے پہلے سائنس، حکمیات، فلسفہ اور اختراعات جدیدہ کے معلومات بہم پہنچائے اور پورے پچاس برس اس نے اس اہم خدمت کو انجام دیا۔ ۱۸۷۶ء میں اس نے اس رسالہ کو جاری کیا تھا اور اب تک اسی طرح پوری شان کے ساتھ جاری رہا۔ ان کی پیدائش ۱۸ء میں ہوئی تھی۔ بیروت امریکن کالج میں تعلیم پائی تھی اور پھر وہیں ریاضیات کے پروفیسر مقرر ہوگئے تھے۔ وہیں اس رسالہ کی اشاعت کا اس کو اور اس کے رفیق فارس نمر کو جو پہلے وفات پاچکا ہے، خیال آیا تھا۔ ترکی حکومت نے اپنی اجازت سے ان کی ہمت افزائی کی۔ آخر یہ مصر میں آکر تکمیل کو پہنچا۔ یعقوب صروف کے بعد فواد صروف نے اس رسالہ کی زمامِ ادارت اپنے ہاتھ میں لی ہے۔

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.
Among the major cucurbit vegetables, Cucumis melo has one of the highest polymorphic fruit types and botanical varieties. The present study was performed to evaluate the morphological and genetic diversity among different genotypes of Snapmelon (Cucumis melo var. momordica) taken from all the four provinces of Pakistan. For the morphological diversity various plant, leaf and fruit parameters were studied according to IPGRI-1998 plant descriptor. Data of these parameters was recorded in 40 genotypes of Snapmelon collected from different parts of the country. Young leaves of these genotypes were collected for DNA extraction through CTAB method, which was used for genetic analysis by SSR Markers. Principle component analysis was used to indicate the morphological diversity among 40 genotypes of Snapmelon collected from diverse origins of Pakistan. These showed the highest phenotypic diversity between the wild and the domesticated genotypes of Hyderabad and Nankana (tehsils), respectively. The morphological markers concluded the fact that the diversity exists in the landraces of Snapmelon in vegetative as well as in the reproductive characters. Moreover, the morphological markers revealed that most of the landraces of same geographical area clustered differently, which depicts the movement of the germplasm to other areas through various means. On the contrary, the results of the qualitative and quantitative analysis showed that the few Snapmelon landraces collected from diverse regions clustered together which indicate some type of commonality of origin among the germplasm of those landraces. The results of this research also support the view that morphological and chemical contents in fruits are reliable in estimating genetic relationships among the landraces of Snapmelon and can be used efficiently for discrimination. This study showed that Pakistani Snapmelon germplasm is a rich source of variation for traits of economic interests. This conclusion came from the high significant differences among the Snapmelon germplasm analyzed for quantitative variables combined with high standard deviation values and the presence of two or more phenotypic classes per trait. SSR markers were also tested on Snapmelon germplasm which yielded valuable information on the genetic relationships of these landraces. The genetic analysis through principle coordinate analysis and dendrogram showed that the 13 wild landraces were distinguished from all domesticated landraces collected from various regions of the country. In conclusion, the genetic diversity exists in various traits of Snapmelon landraces which can be further exploited to develop new combinations through conventional or biotechnological tools.
