Abstract

In this research, experimental and analytical deep drawing of the several-stages design mold is produce hexagonal cup and also proved the influence of the thickness of the sheet on the allocation of strain and laminating in curvature of the cup area for all stages of the drawing. Three stages deep drawing mold was designed and constructed to carry out the experimental work required to produce a hexagonal cup of (28.25 mm by 24.5 mm) , (60 mm) high drawn from a circular flat sheet (80 mm diameter), made from low carbon steel (1006–AISI). Analysis program (ANSYS11.0) to perform the finite element method to accomplish the analytical side of the search. Three types of thickness sheet (t_° = 0.5, 0.7,1 mm) with constant radius of curvature of punch equal to (R_p =4) mm, radius of curvature of die equal to (R_d =8 mm) and radius of curvature of wall of die (R_c= 4 mm) were used. From the experimental and analytical results of the three stages of drawing, it has been found that drawing load less than the more advanced stages of drawing operation on the wall of cup, maximum laminating take place at curvature of the cup area with sheet thickness equal to (t_° =0.5 mm) and maximum thickening take place at the at throat cup with sheet thickness equal to (t_° =1 mm), the maximum values of strains (radial, hoop, thickness and effective) take place at throat cup with sheet thickness equal to (t_° =1 mm).

Abstract

The target of the present work is to synthesize a series of new Citraconimides containing benzothiazole rings. Syntheses of these new cyclic imides were performed via two steps:The first one involved preparation a series of N-(substituted benzothiazole-2-yl) Citraconamic acids via reaction of citraconic anhydride with 2-aminobenzothiazole substituted with different substituent's. The resulted citraconamic acids were dehydrated in the second step via treatment with acetic anhydride and anhydrous sodium acetate or by fusion method to afford a series of desirable N-(substituted benzothiazole-2-yl) Citraconimides. The synthesized compounds were screened for their antibacterial activity against four microorganisms' including [Staphylococcus aurous and Streptococcus pyogenes] (Gram positive) bacteria and [E.coli and Pseudomonas aeruginosa], (Gram-negative) bacteria respectively. The new compounds were found to exhibit good to moderate antibacterial activity .also anti fungal activity of the prepared compounds were tested against [Candida albicans] fungi and some of the tested compounds were found to exhibit good antifungal activity.

الهدف من هذا البحث تحضير مجموعة جديدة من مركبات الستراكونيمايد المعوضة بحلقة البنزوثايوزول . تحضير حلقات الايمايد الجديده هذه تم وفق الخطوتين التاليتين: الاولى تمت من خلال تحضير مجموعة من المركبات من خلال تفاعل الستراكونك انهايدرايد مع 2امينوبنزو ثايوزول المعوضة بعدة معوضات ، وفي الخطوة الثانية تم تجفيف احماض الستراكوناميك من الماء بمعاملتها بالاسيتك انهايدرايد او خلات الصوديوم اللامائية او بطريقة الصهر . تم اختبار فعالية هذه المركبات كمضادات حيوية تجاه بعض انواع الاحياء المجهرية وقد وجد لها اثر ملموس تجاه هذه الفعالية ، وكذلك اختبرت فعاليتها ضد الفطريات واثبتت فعالية جيدة

Abstract

Background & Objectives: The aim of the present study is to investigate the perspective and opinions of a representative sample of social groups regarding physicians' medical ethics' practice. Subjects and Methods: A exploration of point of view of social group conducted by a self-administered questionnaire distributed to a convenient sample from various localities including University of Mosul, primary and intermediate schools, and various governmental and private enterprises. Results: From 48 respondents 54.2% agreed that there are an intentional or unintentional ignorance of patients' rights from the physicians and only 41.7% considered that most of the population has trusted the physicians. On the other hand, more than three quarters (77.1%) of the sample considered that ethical and humanistic side of medical practice are more important than physicians’ scientific qualifications and capabilities. While, half of the study sample (50%) was not sure that most of the physicians have a clear vision about their commitment to patients and society

Abstract

Background: the most common cause of obstructive jaundice is CBD stones, and these can produce significant morbidity and mortality. The management of the obstructive jaundice due to CBD stones is in evolution; several methods of investigations and treatment have been introduced, and each one has its own advantages and disadvantages.Objective: to study and evaluate the management of obstructive jaundice due to CBD stones in Baghdad teaching hospital.Patients and methods: a prospective study of 111 patients with clinical, laboratory, and imaging features suggestive of obstructive jaundice due to CBD stones who were managed in Baghdad teaching hospital over the period from January 2011 to November 2011; other 14 patients with obstructive jaundice due to other causes were excluded. . All patients were symptomatic and had abnormal liver function tests. Transabdominal US was done for all of them, MRCP for 26 patients, and EUS for 9 patients. Four patients had primary stones, 95 patients had secondary stones, 9 patients had retained stones and 3 patients had Mirizzi syndrome.Those patients were subjected to ERCP both to prove the diagnosis and extract the CBD stones. Only three patients sent directly for surgical treatment because they were diagnosed as Mirizzi syndrome. Surgical treatment also was offered for those patients in whom endoscopic management failed. Results: from the 125 patients presented with obstructive jaundice included in this study 14 patients were found to have a periampullary lesions, and they were excluded from the study, so the total number of the patients was 111; 46 males and 65 females Endoscopic management was done for 108 patients with success rate of 90%. Surgical treatment was required in 13 patients, 10 of them following failure of ERCP and the other 3 patients were those with Mirizzi syndrome. The most common complication of ERCP was acute pancreatitis and the most common cause of failure to extract the stones was the size of stone (more than 15mm) Conclusions: Endoscopic sphincterotomy and stone extraction followed by laparoscopic cholecystectomy is still considered the orthodox treatment of CBD stones. Large and multiple CBD stones are the most common causes of failure of endoscopic extraction and indication for surgical treatment. There was higher incidence of retained CBD stones in our study than what was reported in western countries, because there is no intraoperative screening to avoid missing CBD stones in our hospital.Key wards: CBD stones, endoscopic management, surgical intervention
