background: proton induced x-ray emission (pixe) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. materials and methods: five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 mev energy proton beams produced by a van de graff accelerator in vacuum. two specime...

abstract  background: pixe (particle induced x-ray emission) is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. it is very important to know which factors or probably elements act as initial seed and lead to growing the sands. the goal of this study was to compare the relative values of fe/k, cu/k and zn/k for gallst...

The IBA DataFurnace (NDF) is a general purpose program for analysis of IBA data. It currently includes Rutherford backscattering (RBS), elastic (non-Rutherford) backsscattering (EBS), elastic recoil detection analysis (ERDA), non-resonant nuclear reaction analysis (NRA), and particle induced X-ray emission (PIXE). Here we discuss recent developments in the advanced physics capabilities implemen...

Analytical techniques play a fundamental role in heritage science. Among them, Particle Induced X-ray Emission (PIXE) and Fluorescence (XRF) are widely used many laboratories for elemental composition analysis. Although they well-established, strong effort is put on their upgrade, making them suitable more applications. Over the years, at INFN-LABEC (the laboratory of nuclear environment cultur...

Ancient potteries found at Ban Muang Bua, located in northeastern Thailand, associate with Thung Kula Ronghai culture. Most of them are products used daily life and grave goods. The potsherds were examined using techniques based on X-ray spectroscopy. Elemental composition morphology analyzed proton-induced emission spectroscopy (PIXE) scanning electron microscopy coupled energy-dispersive (SEM...

Recently, environmental dust exposure has emerged as a possible risk factor for interstitial pneumonia. Inhaled silica/silicates and titanium are associated with the progression of rapidly progressive pneumoconiosis. However, relationship between inhaled elements idiopathic pulmonary fibrosis (IPF) remains unclear. In this study, we focused on IPF presenting histological usual pneumonia investi...
