An Autopsy Case of a Cavernous Hemangioma with Solitary Fibromatous Fibrosis within the Cavernous Space in the Liver of an Adult.
An autopsy case of a cavernous hemangioma in the liver found accidentally in an adult was reported. It is not so rare to find the small sized hemangioma but unusual to discover a tumorlike fibrous nodule in a solitary state in the central part of the hemangioma. The origin and formation of the fibrous nodule were discussed.departmental bulletin pape

TENSILE STRAIN CAPACITY OF X80 GIRTH WELDED LINEPIPES AND CRACK GROWTH ANALYSIS
ABSTRACT This paper examines the tensile strain capacity of girth welded pipelines. A pressurized and no pressurized full-pipe tension tests were conducted together with FE analyses in order to investigate the strain behavior of pipe under large axial loading with high internal pressure. The critical tensile strain drastically decreased under a high internal pressure condition. Single edge notch tension (SENT) tests with shallow notched specimens were also performed to obtain the material resistance curve (R-curve), and a series of FE analyses was conducted to obtain the crack driving force for ductile crack propagation. The R-curve and crack driving force curve were used in predicting the tensile strain limit of X80 girth welded pipe with a surface defect in the HAZ. The predicted critical tensile strain showed good agreement with that obtained in the pressurized and no pressurized full-pipe tension test
