The decontamination properties of shampoos for cesium, strontium, and cobalt were determined. method has been developed determining the decontaminating shampoos. chemical part study includes preparation hair, which consists forced pollution subsequent washing. Stable isotopes used in work. This increased safety staff during hair research. analytical quantitative determination was carried out by...

Abstract Stable isotope-based dietary information on the tenth century CE Hungarian population serves as a valuable comparative tool to other stable isotope studies in region. This study presents multiproxy approach involving skeletal samples with least diagenetic alteration and best-preserved primary signals. Dental bone collected from three cemeteries northeastern Hungary were investigated us...

Stable isotope ratio analysis (SIRA) of the socalled bioelements (H,C,N,O,S) and the heavy element strontium is applied for food authenticity control and for geographical origin assignment of food products since about 30 years. The first official methods eg for honey and fruit juices have been acknowledged in 1978 and 1981 by AOAC. In 1990 the EU decided to install an official database for wine...

Inherent difficulties of tracking and observing organisms in the field often leave researchers with no choice but to conduct behavioral experiments under laboratory settings. However, results of laboratory experiments do not always translate accurately to natural conditions. A fundamental challenge in ecology is therefore to scale up from small area and short-duration laboratory experiments to ...

Mass spectrometry has served as a major tool for the discipline of proteomics to catalogue proteins in an unprecedented scale. With chemical and metabolic techniques for stable isotope labeling developed over the past decade, it is now routinely used as a method for relative quantification to provide valuable information on alteration of protein abundance in a proteome-wide scale. More recently...
