In this study, we found that nine MAGs belonging to the SAR324 group contained the nifH gene encoding nitrogenase iron protein, indicating SAR324 may participate in N2 fixation, which is a source of nitrogen input to the sediments. Our results show that microbial communities in the sediments ...
It should be noted that for the extended exosphere these missions were mostly limited to hydrogen, whereas oxygen measurements were limited to altitudes below ∼700 km and for nitrogen below ∼600 km, and these measurements are quite old (Johnson1969). However, nitrogen and oxygen are the tw...
Note that Ni is also an essential micronutrient, playing an important role in nitrogen assimilation; therefore naturally present S. trochoidea, but in amounts below the XRF limit of detection (LOD). Metal mixture toxicity: OT micro-XRF analysis complemented by integrated SAXS. We examined the ...
4). A nitrogen mass balance based on the difference between N regeneration and DIN flux shows a small increase in N removal (Nr), coincident with e-SOx development (Table 3). While the increase in Nr is very small relative to the variability between replicate cores, this observation ...
U or fertilizer materials derived primarily from U, enriched with other additional useful additives and plant nutrient materials, can be treated with a solution of NBPT dissolved in one or more amino alcohols to reduce nitrogen volatilization. The solution may be applied as a coating for granular ...
Andreev (Tomsk polytechnic university, Russia) for the help in the preparation, analysis of fluorine-nitrogen gaseous mixtures, and implementation of the liquid-phase fluorination setup. The research was carried out using the equipment of the Center for Sharing Use “Nanomaterials and Nanotechnologies”...
The nutrient composition was determined in the shoots of 5 individual plantlets as 5 replicates per each treatment after oven drying and fine grinding. Total nitrogen was measured using a dry combustion method by a CHN automated elemental analyzer (Vario EL III, Elementar Analysensyteme, Hanau, ...
