Isotopic determination of silicon by mass spectrometry in plants and soils labeled with Si-30
(TAYLOR & FRANCIS INC, 2008)
A method for isotopic determination of silicon by mass spectrometry in plants and soils labeled with Si-30 is reported. The development of this method is for use with studies involving the physiological process of absorption, ...
Incorporation of labeled methionine as a tissue tracer in broiler chickens
(2016-10-01)
The objective of this study was to evaluate the process of L-methionine incorporation in the blood plasma, liver, breast muscle, and abdominal fat of 35- to 59-d-old broiler chickens using the carbon stable isotope (12C ...
ACCUMULATION AND TRANSLOCATION OF SILICON IN RICE AND BEAN PLANTS USING THE 30SI STABLE ISOTOPE
(TAYLOR & FRANCIS INC, 2010)
The 30Si silicon isotope stable was used for assessing the accumulation and translocation of Si in rice and bean plants grown in labeled nutritive solution. The isotopic silicon composition in plant materials was determined ...
Oxoisoaporphines: Regioselective deuterium labelling involving the metastable hydrogenated photoproduct anions
(2011)
During the 1H NMR study of the photoreduction of aza-oxoisoaporphines, aza-OIAs, (7H-benzo[e]perimidin-7-ones) by amines we found an unexpected H/D isotopic exchange in the aromatic positions 4 and 6 of these molecules. ...
Isotope determination of sulfur by mass spectrometry in soil samplesDeterminação isotópica de enxofre por espectrometria de massas (irms) em amostras de solo
(Sociedade Brasileira de Ciência do Solo, 2012)
Sulphur plays an essential role in plants and is one of the main nutrients in several metabolic processes. It has four stable isotopes (32S, 33S, 34S, and 36S) with a natural abundance of 95.00, 0.76, 4.22, and 0.014 in ...
