Quantitative analysis and detection of chaptalization and watering down of wine using isotope ratio mass spectrometry

BIO Web of Conferences, 2019
In early 1990's European Union has established new isotopic approach for detection of wine authenticity. In this article we setup the possibility of using new approach using new EIM – Module – IRMS (Ethanol Isotope Measurement – Module – Isotope Ratio ...

Childhood “stress” and stable isotope life‐histories in Transylvania [PDF]

, 2019
Aims and Objectives Macroscopic skeletal analysis and stable carbon and nitrogen isotope analysis were employed to examine the relationship between skeletal “stress” lesions and changes in the isotopic life history profiles of six nonadults from the ...

Stable isotopes in obesity research

Mass Spectrometry Reviews, 2004
AbstractObesity is recognized as a major public health problem. Obesity is a multifactorial disease and is often associated with a wide range of comorbidities including hypertension, non‐insulin dependent (Type II) diabetes mellitus, and cardiovascular disease, all of which contribute to morbidity and mortality.

Radiocarbon and stable isotope evidence of dietary change from the Mesolithic to the Middle Ages in the iron gates: New results from Lepenski Vir [PDF]

, 2004
A previous radiocarbon dating and stable isotope study of directly associated ungulate and human bone samples from Late Mesolithic burials at Schela Cladovei in Romania established that there is a freshwater reservoir effect of approximately 500 yr in ...

Laboratory evaluation of stable isotope labeling of Culicoides (Diptera: Ceratopogonidae) for adult dispersal studies

Parasites & Vectors, 2019
Background Stable isotope labeling is a promising method for use in insect mark-capture and dispersal studies. Culicoides biting midges, which transmit several important animal pathogens, including bluetongue virus (BTV) and epizootic hemorrhagic disease

Carbon isotope fractionation during aerobic biodegradation of trichloroethene by Burkholderia cepacia G4: a tool to map degradation mechanisms [PDF]

, 2002
The strain Burkholderia cepacia G4 aerobically mineralized trichloroethene (TCE) to CO2 over a time period of similar to20 h. Three biodegradation experiments were conducted with different bacterial optical densities at 540 nm (OD(540)s) in order to test

Stable and radiogenic isotopes as tracers for soil degradation [PDF]

, 2008
Soil erosion seriously threatens mountain slopes. Direct measurement of soil erosion in the field is difficult and needs long term recording. However, stable and radiogenic isotopes are potential tracers for soil erosion estimation and would enable a ...

Stable Isotopes and Trace Elements

, 2011
The stable isotopic and trace element compositions of coral skeletons provide a wealth of information about past environmental conditions in reef settings. Interpretation of existing proxies continues to be refined, while the development of new proxies is shedding light on a range of environmental parameters.
