Angiomyolipoma (AML) are benign tumours composed of varying amounts of thick-walled dysplastic blood vessels, smooth muscle and mature adipose tissue derived from epithelioid cells. We present a previously unreported occurrence of multi-focal pancreatic and hepatic AMLs in a patient and discuss the diagnostic and management difficulties associated with this rare disease. In addition relevant ca...

Structural health monitoring is a developing research field which is multifunctional and can estimate the health condition of the structure by data analyzing and also can prognosticate the structural damages. Illuminating the damages by using piezoelectric sensors is one of the most effective techniques in structural health monitoring. Pressurized equipments are very important components in pro...

Background: Previous studies demonstrated a health improving effect in patients underwent an automatic vibratory massage taking 10 minutes. One of reasons that may explain a healing effect of the automatic massage is a stimulated increase in both blood circulation through vascular system and effective size of blood vessels. Objective: This paper aims to quantify a contribution of the auto...

In this investigation a suitable algorithm for the detection of cracks in the pressure vessels is presented. The equations of motion for the vessel are obtained and transferred into the wavelet space in a simplified form resulted from time and position approximations. The locations of cracks are randomly distributed in different regions of the structure to cover the whole geometry of the pressu...

The integrity assessment to evaluate the safety margin of reactor pressure vessels (RPV) often considers only crack initiation and excludes propagation analysis. This contribution focuses on analysis in RPV steels. eXtended Finite Element (XFEM) method implemented ABAQUS is applied a thick-walled cylindrical specimen with circumferential at inner surface order simulate embrittled subjected Pres...
