Abstract

This is a prospective case control study conducted over a period of two years to evaluate the risk ‎factors of breast cancer in Basrah.‎‎ One hundred and ten female patients with carcinoma of breast were admitted to the general surgical ‎department in three main referral hospitals in Basrah and those attended to Basrah breast clinic, ‎compared with (140) women who had no breast cancer from the population as a control group were ‎included in the study. The patients were diagnosed to have breast cancer according to the results of fine ‎needle aspiration cytology biopsy and the results of histopathological examination of excisional biopsy ‎taken from the primary growth in the breast.‎‎ The study involved history, physical examination, laboratory & radiological investigations, ultrasonic ‎study and the results of fine needle aspiration cytology biopsy and histopathological examination.‎‎ The data showed that the range of age of the group affected was (41-50 years); the patients were ‎mostly from urban areas (66.36%); the married patients were most commonly affected than single ‎patients (77.27%). Most of them (76.3%) had a history of breast feeding and (27.2%) of patients had a ‎history of contraceptive pills taking. ‎‎ Sixty two patients had acceptable range of body mass index, and seven patients only had a family ‎history of breast cancer.‎‎ The study showed that the epidemiological pattern of the risk factors of breast cancer were altered to ‎some extent according to the environmental, psychological and nutritional changes that occurred in our ‎country in the last decades.‎

Abstract

In this study induced air flotation (IAF) through Perspex glass column (ID 10cm and 150 cm heights) has been studied experimentally to treat the oily wastewater of Iraqi North Oil Company. The column operated in a semi-batch mode (batch wastewater, continuous air injection). Different samples of oily wastewater (30,100,800ppm) were used. Air introduced at different superficial gas velocity through porous (pore size 120µm) distributor which located at the bottom of column. Different speed of the stirrer (50 to 250) rpm was used to indicate it effect on the removal efficiency of oil from water.The study showed that the removal efficiency of oil was increased with increasing initial oil concentration, it reached up to 76 %. While it became 89% when using stirrer.The experimental results were translated to a computer program to predicate empirical correlation.

في دراسه عمليه التطويف المستحث من خلال عمود التطويف (القطر الداخلي 10 سم وبارتفاع 150 سم) تمت عمليه معالجه الماء الملوث بالنفط لشركه نفط الشمال العراقيه. العمود يعمل بنظام شبه وجبه (وجبه من الماء الملوث وضخ للهواء مستمر). تم اخذ عينات مختلفه من الماء الملوث بالنفط بتراكيز(30,100,800) جزء بالمليون. الهواء الداخل بسرع مختلفه من خلال الثقوب (حجم الثقب 120 مايكرومتر) حيث ان الموزع يقع في نهايه العمود. سرع مختلفه من الخلاط المستعمل تتراوح من (50الى 150)دوره بالدقيقه لمعرفه مدى تاثير هذه السرع على كفاءه ازاله النفط من الماء. الدراسه بينت ان كفاءه الفصل للنفط تزداد بزياده التركيز الابنتدائي للنفط , وقفزن من 76% الى 89% باستخدام الخلاط. النتائج العمليه ترجمت بواسطه انظمه الحاسوب لاسناد الارتباط التجريبي.
