Details of a numerical and experimental investigation on the heat transfer characteristics for three-dimensional turbulent flows in rectangular duct with punched Delta Cut Winglet are presented present article. The aim study is to examine influence winglet shape, attack angles 00 , 30°, 45°, 60°, 900 different patterns viz., Inline Staggered, Height Perforation H/2, H/3 H/4, Diameter 2.5mm, 3.2...

intraductal papillary mucinous neoplasms (ipmns) are rare pancreatic tumours, accounting for less of 1-2% of all neoplasms of the gland. main characteristics of ipmns are their favourable prognosis as these pre-malignant or frankly malignant lesions are usually slow-growing tumours and radical surgery is frequently possible. according with the localization of the lesions, three different entiti...

bile duct tumor is difficult because of ambiguity caused by the abundant mucin secretion and/or by the superficial mucosal spread of the tumor along the bile duct [1]. We report the case of a 77-year-old patient, who initially presented with severe jaundice, right upper abdominal pain, and fever. The endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a large amount of viscous mu...

Two groups of subjects classified as high vs. low in the need for power (n power) were assessed for augmenting versus reducing in the event-related potential (ERP) elicited by neutral and power-related words. Words at four different intensity levels in each of these two classes were randomly presented and ERPs in response to each word class at each of the four intensity levels were computed fro...

The spacial characteristics of an underground common duct often lead to disasters resulting in great damage life and property. In the case a cable fire, additional damages such as failure power fire prevention equipment occur. Accordingly, derive risk factors cone calorimeter test was performed this study. simulation factor obtained by measuring temperature changes with time, while heat release...

developmental midline perinasal masses in children are rare lesions specifically in association with choristomas. we encountered a 3-year-old boy with epiphora, a striking mass on the nasal bridge and ipsilateral nasal hypoplasia. ct scan imaging showed multiple calcified areas within the tumor in addition to linear defect in frontal bone, hypoplastic left ethmoidal sinus and left nasal cavity,...

abstract background: thyroglossal duct cysts (tdc) are the most common congenital neck masses arising from the expansion of the epithelial tract remnants occurring during embryogenic thyroid migration. about 7% of the population have thyroglossal duct remnants. clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. thyroglossal duct cysts may ra...

thyroglossal duct cysts are the most common form of congenital cysts on the neck. the incidence of thyroid papillary carcinoma in thyroglossal duct cyst is less than 1%. in most cases the diagnosis is made postoperatively. we present a 22-year-old female with thyroid papillary carcinoma arising from thyroglossal duct cyst,identified in pathologic study after sistrunk operation.in our case there...
