Monte Carlo simulations have been used to derive the relationship between the counting efficiency and both the chest wall thickness and adipose mass fraction as a function of photon energy. Adipose mass fraction can be eliminated by the use of the de

A fundamental assumption made in calibrating a lung counter is that the deposition of radioactivity in the lung is homogeneous; however, depositions rarely follow this pattern. There will be an uncertainty on the activity estimate if the lung counter

There have been recent reports of high nitrite concentrations occurring in both terrestrial and aquatic ecosystems. In the present study, modelling procedures were applied to results from soil incubation studies in order to quantify the relative cont

Previous studies have reported that only 40% of nitrite (NO 2 - ) in major rivers in Northern Ireland originates from land drainage. The remainder appears to originate from N transformations at the interface between sediment and water within river sy

The flux of N2O from soil can be due to nitrification or denitrification. Since aerobic and anaerobic microsites can develop within the same soil aggregate, nitrification and denitrification could be occurring at the same time. The contribution of ni

Recent studies have shown relatively high nitrite concentrations occurring in soil. The contribution to nitrite accumulation of the two major source processes, nitrification and denitrification, was studied by differential 15N-labelling of nitrate an

Traditionally nitrite is viewed as a transient intermediate in a number of processes. Recent studies have shown that NO2− can occur in relatively high concentrations in soil and may be the source of concentrations in river water above EU guidelines

Concentrations of NO2−N in land drainage and river waters in Northern Ireland in recent years have frequently exceeded EEC guide values. Very little information exists to indicate if and when NO2− accumulates in soil solution, and whether NO2

Late-onset Alzheimer's disease (LOAD) is a multifactorial disease with the potential involvement of multiple genes. Four recent genome-wide association studies (GWAS) have found variants showing significant association with LOAD on chromosomes 6, 10,
