Structural Characterization of Steatite Vessels of Shadyakh by XRF, XRD and SEM Techniques
Using the stones to make tools and vessels dated back to Paleolithic and Neolithic periods. Stones so called soft stones, along with the alabaster, are one of the most famous stones that have been used to produce vessel in Near East, where they are in use currently in different applications. Soft stone vessels reach to highest level of flourishing during the Bronze Age and its geographical exch...
متن کاملMicro-sr-xrf and Micro-pixe Studies for Archaeological Gold Identification
For gold, the most promising elements for provenance are Platinum Group Elements (PGE), Sn, Te, Sb, Hg, Pb, but also high melting point elements, such as Ta and Nb. Small fragments of native Carpathian gold placer and primary were studied using Synchrotron Radiation X-Ray Fluorescence at ANKA synchrotron. The goal of the study was to identify the trace elements, especially Sn, Sb and Te. The me...
متن کاملsemi-analytical solution for static and forced vibration problems of laminated beams through smooth fundamental functions method
در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولTrace Element Profiling of Gunshot Residues by PIXE and SEM-EDS: A Comparative Study
We critically compare particle induced X-ray emission (PIXE) on the ion microprobe with scanning electron microscopy with energy dispersive X-ray spectroscopy (SEMEDS) for the characterisation of gunshot residues (GSR). Samples of gunshot residue from several different firearms were collected. Individual particles of GSR were analysed by SEM-EDS using a 30keV electron beam focussed to ~10nm and...
متن کاملPIXE and XRF analysis of honey samples
The systematic determination of trace-element concentrations in honey samples was done by the PIXE method using a 2 MeV proton beam and by the total reflection XRF method. The different kinds of honey samples were collected in the period of spring–summer in three places of Poland: in the centre of Warsaw (a highly polluted region) and about 100 km east of Warsaw and 70 km southwest of Warsaw (a...
