Isotopic signatures of N O can help distinguish between two sources (fertiliser N, or endogenous soil N) of N O emissions. The contribution of each source to N O emissions after N-application is difficult to determine. Here, isotopologue signatures of emitted N O are used in an improved isotopic model based on Rayleigh type equations.

Global atmospheric ethanol budget models include large uncertainties in the magnitude of ethanol emission sources and sinks. In order to apply stable isotope techniques to constrain ethanol emission s...
The nanoSIMS-based chemical microscopy has been introduced in biology over a decade ago. The spatial distribution of elements and isotopes analyzed by nanoSIMS can be used to reconstruct images of bio...
Quantification of cellular deoxyribonucleoside mono- (dNMP), di- (dNDP), triphosphates (dNTPs) and related nucleoside metabolites are difficult due to their physiochemical properties and widely varyin...
Stable isotope analysis is used to understand the foraging habits and movements of a diverse set of organisms. Variability in stable isotope ratios among tissues derived from the same animal makes it ...
Measurements of the stable isotope ratios of nitrogen (N/N) and oxygen (O/O) in nitrate (NO) enable identification of sources, dispersal, and fate of natural and contaminant NO in aquatic environments...
The distribution of stable (non-radioactive) isotopes in living organisms is increasingly studied, in particular the zinc (Zn), copper (Cu) and iron (Fe), not only in primitive organisms, ...
This study evaluates the effectiveness of an enhanced package of support for activities described in the "Standard Operating Procedures (SOP) for Patient Tracing in Health Facilities in Zi...
For assessing body retinol pools in preschool children, it is recommended that a blood sample is taken 14-21 days after isotope dosing. During this period, dietary intake of vitamin A shou...
Daprodustat administration has the potential, by virtue of increasing hypoxia-inducible factor (HIF) levels, to increase oral iron absorption and incorporation into hemoglobin (Hgb). There...
Conventional indirect indicators of iron status, using serum and red blood cell biomarkers, are confounded by inflammation from common infections in sub-Saharan Africa, a region with a hig...
Identification of those persons (or animals) who have had such an association with an infected person, animal, or contaminated environment as to have had the opportunity to acquire the infection. Contact tracing is a generally accepted method for the control of sexually transmitted diseases.
Statistical formulations or analyses which, when applied to data and found to fit the data, are then used to verify the assumptions and parameters used in the analysis. Examples of statistical models are the linear model, binomial model, polynomial model, two-parameter model, etc.
Hydrogen. The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight 1. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
Adaptive antiviral defense mechanisms, in archaea and bacteria, based on DNA repeat arrays called CLUSTERED REGULARLY INTERSPACED SHORT PALINDROMIC REPEATS (CRISPR elements) that function in conjunction with CRISPR-ASSOCIATED PROTEINS (Cas proteins). Several types have been distinguished, including Type I, Type II, and Type III, based on signature motifs of CRISPR-ASSOCIATED PROTEINS.
Theoretical models simulating behavior or activities in nursing, including nursing care, management and economics, theory, assessment, research, and education. Some examples of these models include Orem Self-Care Model, Roy Adaptation Model, and Rogers Life Process Model.
