The determination of the number and the molecular and isotopic
composition of the gases used as reference materials.
2 We report a case of rupioid psoriasis developing as isotopic
response after chicken pox.
Here we present an alternative method of isotope analysis that could overcome a number of constraints and therefore has potential for wider adoption of isotopic
techniques as part of AW-IPM programs.
In this study, isotopic
turnover rates, discrimination factors, and C:N ratios were used as indicators of diet performance and nutrient assimilation of larvae in relation to their diet (Roth & Hobson 2000.
This was considered to be a variant of the isotopic
Most bulk nitrogen isotopic
records have suggested that [N.
The expectation has long been that the moon should carry the isotopic
"fingerprint" of the foreign body, which scientists have named Theia.
If the isotopic
data are normally distributed, traditional parametric statistical analyses (e.
In this study, we investigate the isotopic
signal of periphyton, phytoplankton, sediment, riparian vegetation, aquatic macrophytes, and grasses, because those sources can be constituents of POC mixture.
Fishes were fed twice a day at 10:00 and 16:00 h, with commercial extruded fish food containing crude soybean protein, in which the isotopic
values of carbon and nitrogen, previously analysed, were -19.
We used the isotopic
signature of alanine, an amino acid and building block of protein that essentially traps the carbon from dietary sugar so that it can be measured in the protein component of hair or blood.
Product offerings include both isotopic
kits, bulk antibodies, tracers and related products.
