پیکر تراشی

اسے امیجری یا صورت گری بھی کہا جاتا ہے۔ شاعر اپنے قلم سے اور اپنے الفاظ سے اپنے مقصد کو دلکش انداز میں بیان کرتا ہے امیجری کے اس پہلو کو آگے بڑھاتے ہوئے پیکر تراشی کے تحت اس کی تفصیل بیان کی جاسکتی ہے۔ پیکر تراشی کو صورت گری یا امیجری بھی کہا جاتا ہے۔ قابل تحسین ہیں ڈاکٹر تو قیر احمد خاں صاحب کہ جنہوں نے ”امیجری“ کا عنوان تحقیق کے لیے منتخب کیا۔ پروفیسر تو قیر احمد خاں نے پہلے پروفیسر عبدالحق کی نگرانی میں ایم۔ فل اور پھر پی۔ ایچ۔ ڈی کا مقالہ مکمل کیا۔ ڈاکٹر تو قیر احمد خاں کا ایم فل کے مقالے کا عنوان ” بال جبریل کی امیجری" تھا۔ دونوں مقالے اب کتابی شکل میں دستیاب ہیں جس سے امیجری کے موضوع کو وسعت میسر آئی۔ اپنی تصنیف " اقبال کی شاعری میں پیکر تراشی“ کے حرف آغاز میں ڈاکٹر تو قیر احمد خاں نے پروفیسر عبدالحق کا شکریہ ان الفاظ میں ادا کیا ہے:
”یہ مقالہ فکر اقبال کے شناور ، معروف محقق اور نقاد استاذی ڈاکٹر عبدالحق کی نگرانی
میں پایہ تکمیل کو پہنچا جن کی متفق رہنمائی اور اخلاق کریمانہ کے بغیر اس امر کی
تحمیل آسان نہ تھی “ (26)
ڈاکٹر توقیر احمد خاں نے پیکر تراشی پر تفصیلی گفتگو کی ہے۔ پروفیسر عبدالحق نے اقبال کی شاعری کے دلکش پہلوؤں کا جائزہ لیتے ہوئے ان میں پیکر تراشی کی رقصاں تصویروں کا ذکر کیاہے۔ کہتے ہیں:
”اقبال کی نظموں میں پیکر تراشی کی رقصاں، متحرک اور منہ بولتی تصویر میں ان
تخلیقات کی صناعی میں اضافہ کرتی ہیں “ (27)
اقبال کے یہاں تشبیہ اور استعاروں کے علاوہ پیکر تراشی کے بھی بہت سے نمونےدیکھے جا سکتے ہیں۔ یہ انمول نمونے اقبال کے فن کو جاوداں بنا دیتے ہیں۔ پروفیسر عبد الحق کہتے...

أثر مؤشرات التغري املناخي يف انتشار بعض اإلمراض املعدية يف حمافظة ذي قار

The study examines the impact of climate change on the spread of some diseases in Thi- Qar Province through collecting and analyzing data about various weather elements and phenomena of some monitoring stations ( Nasiriyah ) for a high-temperature climatic cycle of 78 years (1941-2018). It is divided into seven consecutive and different time periods, 1941-1951, 1952-1962, and 1963-1973, 1974-1984, 1985-1995, 1996-2006, 2007-2018. These elements and phenomena are solar radiation, temperatures (maximum and minimum), wind (Dust storm, rising dust, suspended dust), and the thermal extremes phenomenon (heat and cold waves) The research aims to reveal the reality of trends in climate of the province of thi qar, and find out the reality of the general trend of the elements of climatic different by relying on a series of evidence statistical number of climatic variables for the meteorological station in Nasiriyah especially temperature, wind speed, relative humidity and rainfall, and extreme dust The most important results of the research showed that temperatures trending upward in sync with a clear reduction in the amount of relative humidity and rainfall which threatens a sharp repeating the phenomenon of drought in the future. The research study has found that the City of Nasiriyah ranked first in human diseases for the period 2009-2018, as the reasons for this level of diseases include that Nasiriyah is subject to the recurrence of dusty weather phenomena due to its proximity to the Western Desert Plateau, as well as the lack of cultivated and water-covered areas. This city witnesses serious air pollutions due to the concentration of a large number of factories located near inhabited areas, as well as, the spread of brick factories in the regions of the city, such as, brick factories in the area of El-Islah. This is public services, in addition to the building projects, deterioration of sewage overflow, the spread of epidemics and insects harmful to human health, other climatic environmental pollutants, such as the spread of pollen, plant scents and air allergens, which contributed to the increase in the severity of skin diseases, climate eyes, arthritis and respiratory allergies. The city of Al-Shatra ranked second in the number of people with climatic diseases, Al-Rifai ranked third with infected cases, Souk Al-Shuyoukh ranked fourth, and finally Al-Jibayish ranked fifth and last in people with climatic human diseases for the period 2009-2018 in Dhi- qar province due to the same geographical, climatic, medical, and environmental causes indicated earlier.

Phytochemical and Biological Studies of Euphorbia Serpens, Euphorbia Granulata Euphorbiaceae and Vernonia Cinerascens Compositae

The present research work emphasis on the biological and Phytochemical studies of the medicinal plants Vernonia cinerascens (Compositae), Euphorbia granulata and Euphorbia serpens (Euphorbiaceae). Dichloromethane and methanol extracts of the different parts of Vernonia cinerascens, Euphorbia granulata and Euphorbia serpens were prepared. These extracts were subjected to a battery of biological screening and it was observed that dichloromethane extracts of Vernonia cinerascens roots and that of Euphorbia granulata whole plant exhibited significant antifungal activity against Microsporum canis. Microsporum canis is responsible for tinea capitis and tinea corporis. Methanol extract of Vernonia cinerascens also showed significant antifungal activity against Fusarium solani. Fusarium solani is a pathogen responsible for fungal infections in plant and human. Dichloromethane and methanol extracts of Euphorbia serpens exhibited moderate antifungal activity against Aspergillus flavus. Methanol extracts of Vernonia cinerascens and Euphorbia serpens showed antioxidant activity. All the extracts have dose dependent spasmolytic activity. Dichloromethaneextract of Vernonia cinerascens root was subjected for Phytochemical investigations and afforded a new monoterpene, (3β-acetoxy-5α-angeloyloxy-7-deoxy-carvotacetone). Methanol extract of the same plant when subjected for isolation offered a new flavone (5,4''-dihydroxy-7-(4-hydroxybenzoyl)-3''-methoxyflavone) and eight known compounds, namely, 2-hydroxy-3-methoxy-5-(2′-propenyl)-phenol, vanillic acid, isoferulic acid, caffeic acid, methyl gallate, uridine, 3''-methylquercetin and quercetin.
