The goal of this research was to evaluate the chemical composition of some herbal products consumed in Brazil through the Energy Dispersive X-ray Fluorescence (EDXRF). The methodology used encompassed the selection of 14 plants’ dried extracts and six gro... see more

Determination of scientifically grounded criteria that allow us to objectively diagnose damage to clothing caused by firing elastic bullets of “Teren-12P” cartridges, which are in service with Ukrainian law enforcement agencies, is currently an urgent pro... see more

The precolonial Guarani used to be spread over large areas in South America, especially in regions of the Prata River basin and Brazil’s coastal areas. Their great feature in terms of material culture is their ceramic production, especially for containers... see more

The main objective of this study was the chemical determination of elements present in the sample (archaeological fragments), used the X-ray fluorescence techniques. Three analytical techniques were used: (i) conventional energy dispersive X-ray fluoresce... see more

A new methodology based on a portable X-ray fluorescence (pXRF) was applied in this work to analyze the geochemical dispersion halo of a sulfide mineralization along the Bule Stream sediments (Ouro Branco, Minas Gerais State, Brazil). The study area, loca... see more

Summary. Treatment of tooth-maxillary anomalies and deformities, in particular in adult patients, is a topical problem in modern dentistry. Movement of teeth during orthodontic treatment is accompanied by resorption and the formation of a new bone tissue ... see more

The work presents the results of method development for matrix effects correction in X-ray fluorescence measurements of Ti, Mn, Fe and U concentrations in the silicate-type uranium ore samples using wavelength dispersive XRF spectrometer S 8 Tiger (Bruker... see more

Nuclear techniques and other techniques using ionising radiation represent a valuable tool in non-destructive diagnostics applied to archaeological finds and objects of arts, namely for determining the composition of materials used in the production of ar... see more

The aim of the research was to determine features of the elemental composition of polyfloral honey from the Odessa region (Ukraine) by the method of x-ray fluorescence for using these features in the geographic marking of the region of honey origin. A cho... see more
