hydatid cyst is a zoonotic disease that is common in the mediterranean region. thoracic wall, rib or extrapulmonary intrathoracic localization of the cysts is very rare. giant extrapulmonary intrathoracic hydatid cysts can lead to both diagnostic and treatment difficulties and can be confused with tumor. we present a case of a hydatid cyst with thoracic wall involvement mimicking tumor. we conf...

in spite of the fact that cementitious and concrete materials are mainly used on a large scale and inhuge quantities for roads, dams, bridges and building constructions, the mechanical behavior of thesematerials depends to a great extend on structural elements and phenomena which are effective on amicro and nanoscale. although this is well known by researchers, material producers and engineersf...

Surfactants are widely used in bakeries as dough strengtheners and dough improvers but there is a wide range of compounds available according to their mode of action that could potentially improve the quality of not only the simple breads and doughs but also of frozen dough. These types of product usually have a short shelf-life when compared with normal bakery products. With the increase in mo...

background and objective: mediastinal masses in children are a heterogenous group of asymptomatic potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. materials and methods: the clinical and laboratory features of 65 patients who had open biopsies in ali-asghar hospital over 11 years were reviewed. results: seventy-...

osteosarcoma (osteogenic sarcoma: os) is the most common primary malignant bone tumor of long bones, whereas primary osteosarcoma of chest wall, especially in sternum, is extremely rare. we report a 57-year-old man with an immobile slow growing mass located in the middle of the sternum. the patient had no significant pain or tenderness and the past medical history was not remarkable. ct-scan sh...

An imminent food crisis reinforces the need for novel strategies to increase crop yields worldwide. Effective control of pest insects should be part of such strategies, preferentially with reduced negative impact on the environment and optimal protection and utilization of existing biodiversity. Enhancing the presence and efficacy of native biological control agents could be one such strategy. ...

background some sonographic positions for detection of abdominal wall hernias needed .in this paper we described the sonographic technique of abdominal wall hernia. methods from june 2013 to july 2016, three hundred seventy four patients referred in our department for evaluation of abdominal wall hernia (median age, 38 years; range 2 - 86 years). one hundred and ninety patients had abdominal he...

background & objective: abdominal cutaneous and subcutaneous nodules are uncommon lesions which may be benign or malignant. majority of the malignant nodules are metastatic in origin and may be the initial presentation of primary malignancy, hence an early diagnosis is important. our aim was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous a...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...
