Abstract

Hydatid cysts of the liver and/or lung are commonly seen in surgical practice in endemic areas like Iraq. Primary or secondary skeletal muscle hydatidosis is rarely reported, even in endemic areas. This is a case report of a 51 year-old, otherwise healthy, man with a firm non-fluctuant cystic swelling in the right thigh that was painless and growing slowly over a period of six months. While ultrasound and magnetic resonance imaging suggested a multilocular cystic lesion, other investigations failed to confirm the diagnosis of muscular hydatid cysts, especially in the absence of a primary cyst in the more common organs. The lesion was initially considered a soft tissue tumor but intraoperative exploration revealed a hydatid cyst with daughter cysts, that was excised and the patient was treated with Albendazole for 1 month postoperatively. The patient developed a seroma that disappeared spontaneously. There was no recurrence for up to 4 months of follow-up. This report illustrates that echinococcal disease should be considered in the differential diagnosis of a cystic mass in any anatomic location, especially when it occurs in endemic areas.

Abstract

The present work devote the effect of shot peening time on the mechanical properties for two aluminum alloys AA2017-T4 and AA6063-T5. The test carried out using standard tensile specimens under various shot peening times. The results showed that the increase in yield and tensile strength values. The maximum increasing at 15 minute for AA 2017-T4, and at 9 minute for AA 6063-T5. The maximum values of strain hardening factor (n) and strength factor (k) are recorded at 15 minute for AA 2017-T4 while recorded the maximum values of (n) at 24 minute and (k) at 9 minute for AA 6063-T5. The results showed that the percent elongation are increased to maximum value at 9 minute for AA 2017-T4 while the minimum value was at the same time for AA 6063-T5.

اشتمل البحث على بيان تأثير القصف بالكرات الفولاذية على الخواص الميكانيكية لنوعين من سبائك الألمنيوم ( (AA2017-T4 و (AA6063-T5). اجري الفحص على عينات شد قياسية تحت تأثير أزمان قصف مختلفة. أكدت النتائج زيادة في قيم مقاومة الخضوع ومقاومة الشد لتسجل أعلى زيادة عند زمن (15) دقيقة لسبيكة AA2017-T4)) و(9) دقيقة لسبيكة ((AA6063-T5. سُجلت أيضا أعلى قيم لمعامل الاصلاد الانفعالي (n) و معامل المتانة (k) عند زمن (15) دقيقة لسبيكة (AA2017-T4) بينما سُجلت أعلى قيمة (n) عند زمن (24) دقيقة وقيمة (k) عند زمن (9) دقيقة لسبيكة AA6063-T5)). أوضحت النتائج أيضا إن نسبة الاستطالة تزداد لتبلغ أعلى قيمة لها عند زمن (9) دقيقة لسبيكة AA2017-T4)) بينما سجلت أدنى نسبة استطالة لسبيكة AA6063-T5)) عند ذات الزمن.
