The Nitrogen Compounds of the Fundamental Rocks [PDF]

The Journal of Agricultural Science, 1908
It has been shown that many rocks, when samples are taken from such a depth as precludes all possibility of weathering, contain nitrogen in amounts comparable to those present in soil, especially when the strata consist of indurated clays like the Lower Lias, Oxford, Kimmeridge or London Clay. Since the rocks also contain carbon the nitrogen is without

Nitrogenous Compounds in Hemodialysate [PDF]

Circulation, 1964
Correlation of clinical and chemical changes in patients with uremia has not been possible for substances other than urea and electrolytes. Since clinical improvement is frequently seen following hemodialysis, examination of the dialysate for substances of possible importance seemed warranted.

1,4,6,10-Tetraazaadamantanes (TAADs) with N-amino groups: synthesis and formation of boron chelates and host–guest complexes

Beilstein Journal of Organic Chemistry, 2022
A synthetic route to 1,4,6,10-tetraazaadamantanes (TAADs) bearing free and protected amino groups at the bridge N-atoms has been developed via intramolecular cyclotrimerization of C=N units in the corresponding tris(hydrazonoalkyl)amines.

Groundwater chemistry, pollution, and health risk assessment for nitrogen compounds. A case study in a suburban region of Romania

Romanian Journal of Ecology & Environmental Chemistry, 2022
As groundwater is used as a source of drinking water, monitoring its quality is essential due to possible adverse effects on human health. Nitrogen compounds (nitrates, nitrites, ammonia) within certain concentration limits are natural components of the ...
