Sentence examples for deficient sites from inspiring English sources

The reduction of extractable soil phosphorus with increasing OM removal on these already phosphorus deficient sites may affect tree growth in the future but have not yet translated to stand volume differences over 10 years.

The putative pharmacophoric elements common to all potent α4β2 ligands include (1) a basic or quaternized nitrogen atom, and (2) a less basic nitrogen or a carbonyl oxygen that presumably interact with electron rich and electron deficient sites on the receptor, respectively.

There are three deficient sites around the perineurium: near the nerve ending, at the site invaded by the blood vessels present in nerves, and at the site invaded by the reticular fiber [ 93, 94].

We therefore analysed the contribution of each of the membrane interaction sites to NPC assembly by substituting endogenous Nup53 with constructs defective in the N-terminal membrane interaction site, lacking the C-terminal membrane interaction site, or comprising a combination of both deficient sites.

Based on the results of this study, we recommend organic matter retention during harvest and site preparation on N-deficient sites such as Pinaki Typic Sandy Recent Soil.

Our results indicate that white ash health is strongly influenced by site nutrition, and defoliation can trigger declines in cation-deficient sites.

Two studies (Leonard 1977; Neary and Leonard 1978) covering a range of New Zealand sites with varying geology, climate and hydrology found fertiliser application to trees on nutrient-deficient sites resulted in short-term increases in N and P in forest stream waters.

This so-called "reactive" intramolecular charge-transfer state creates an electron-deficient site across the double bond to trigger the subsequent nucleophilic attack of NADPH, by the negatively charged hydride from nicotinamide adenine dinucleotide phosphate.

However, this peak is absent in the "reactive" ICT state, providing further evidence that the electron-deficient site at the C17-C18 doubondbond is formed as a result of excited-state interactions with the C17 carboxyl group.
