OBJECTIVE To assess the diagnostic value of various ultrasound (US) findings and to make a decision-tree model for US diagnosis of biliary atresia (BA). MATERIALS AND METHODS From March 2008 to January 2014, the following US findings were retrospectively evaluated in 100 infants with cholestatic jaundice (BA, n = 46; non-BA, n = 54): length and morphology of the gallbladder, triangular cord t...

Heat transfer enhancement (HTE) efforts spent during the last half-century have become one of most important working areas researchers from both academia and industry. One popular passive methods, with regard to price-performance ratio, is place wire coils in a pipe or duct. In this study, heat pressure drop characteristics diamond, triangular, circular cross-sectional (DWC, TWC, CWC) square du...

The cooling performance of the air-conditioning system in electric vehicles could be enhanced through geometrical optimization air ducts. Furthermore, it has been proven that heat-transfer divergent channels is better than conventional channels. Therefore, present study investigates thermal and flow characteristics ducts with various rib shapes for vehicles. characteristics, namely, temperature...

in this paper, some elementary operations on triangular fuzzynumbers (tfns) are defined. we also define some operations on triangularfuzzy matrices (tfms) such as trace and triangular fuzzy determinant(tfd). using elementary operations, some important properties of tfms arepresented. the concept of adjoints on tfm is discussed and some of theirproperties are. some special types of tfms (e.g. pu...

In this study, spermatheca and eggs of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae were examined by light microscope SEM. The have ~1.30 mm length 0.94 width. Newly laid turn from white to yellow as soon embryonic differentiation. P. egg surface shows polygonal (usually hexagonal pentagonal) shapes. pipe shaped 6-7 micropylar projections. egg-burster which is a dark T-shaped or triangular p...

conclusion non-mass-like lesions, lesions with focal or segmental distribution, with a “plateau” enhancement curve type were the most frequent findings of dcis lesions on mri. background adequate diagnosis of ductal carcinoma in situ (dcis) could lead to efficacious treatment. due to the fact that dcis lesions can progress to invasive carcinomas and that the sensitivity of the standard examinat...
