necrotizing soft tissue infections (nstis) are polymicrobial infections with high morbidity and mortality. we report a case of retroperitoneal nsti in an immunocompetent young male, with clinical symptoms and signs mimicking acute pancreatitis (pseudo-cullen’s and pseudo-grey-turner’s signs). the initiating lesion was a pustule which progressed and mimicked acute pancreatitis. ct scan showed fe...

Automatic segmentation of liver in medical images is challenging on the aspects of accuracy, automation and robustness. A crucial stage of the liver segmentation is the selection of the image features for the segmentation. This paper presents an accurate liver segmentation algorithm. The approach starts with a texture analysis which results in an optimal set of texture features including high o...

A number of important anatomical features and chemical composition in opposite, normal, and compression wood of Norway spruce (Picea abies) were evaluated to optimally utilize spruce logs containing compression wood. A comparison of axial tracheid and ray cell features in the opposite, normal, and compression wood was provided. Lignin, cellulose, acetone-soluble, and water-soluble extractive co...
