Nanomineralogy of gemstones: From genesis to discovery
Nanomineralogy is the study of Earth and planetary materials at nanoscales, focused on characterizing nanofeatures (like inclusions, exsolution, zonation, coatings, pores) in minerals and rocks, and revealing nanominerals and nanoparticles [1]. With advanced high-resolution analytical scanning electron microscope, we are now capable to characterize solid materials easier and faster down to nano...
متن کاملX-Ray Fluorescence Analysis of Gemstones
The energy dispersive X-ray fluorescence analysis (ED-XRFA) is a well-established tool for multielement composition analysis in different fields/1/. It works non-conducting and it is non-destructive. No particular sample preparation is necessary if the specimens have an almost planar and smooth surface. For the characterization of precious gemstone material it is also important that the deposit...
متن کاملImpact of Echinococcosis on Quality of Sheep Meat in the South Eastern Kazakhstan
A survey of 2,123 slaughtered adult sheep in markets of the south-east Kazakhstan established that the average contamination of animals by Echinococcus granulosus is 9.1% with primary localization of cysts in livers and lungs. The histologic structure of the muscle tissue of infected sheep displayed destructive changes with a prevalence of granular dystrophy. The amount of protein, fat, calcium...
متن کاملNew Genetic Lineage of Tula Hantavirus in Microtus arvalis obscurus in Eastern Kazakhstan
Genomic sequences of Tula (TULV) hantavirus were recovered from tissue samples of European common voles Microtus arvalis (subspecies obscurus) captured in Kazakhstan, Central Asia. Phylogenetic analysis of the S genomic segment of Kazakh TULV strains showed that they form distinct, well supported genetic lineage and share a more ancient common ancestor with two Russian lineages of TULV. The ded...
متن کاملEchinococcosis, toxocarosis and toxoplasmosis screening in a rural community in eastern Kazakhstan.
OBJECTIVE To determine the extent of carnivore-transmitted parasitic zoonoses in a community in eastern Kazakhstan, a region where cystic echinococcosis (CE) re-emerged in recent years. METHODS Cross sectional ultrasound study of 3126 human subjects to determine the extent of human cystic and alveolar echinococcosis (AE). Blood samples were taken from each subject and analysed for antibodies ...
