(see bottom ofFig. 1). Theglobal nitrogen cycleencompasses the N cycle of the earth and includes the transfer of mass among the earth's biogeochemical reservoirs: oceans, lakes, rivers, groundwater, the atmosphere, terrestrial biosphere, and geosphere (Fig. 1). Increases in the transfers of ...
others, including the United States and Germany, however, serum urea concentration is referred to indistinctly asblood urea nitrogen(BUN) or serum urea nitrogen (SUN), and is expressed as the mass concentration of nitrogen equivalents. The conversion between different units is shown in formula 1....

Response of Dasysiphonia to elevated nutrients and/or pCO2 Growth rates ofDasysiphoniawere responsive topCO2levels during experiments performed in winter, spring and fall (February, March, April, October, and November), where a higher level ofpCO2significantly increased growth relative to ambientpCO2...
Relative growth rates (RGR, % days−1) were estimated after measuring photosynthetic rates and Chlorophyllafluorescence by the difference in fresh weight (FW) after 3 days of incubation, using the formula: $$RGR={\rm{In}}(\frac{Wt}{{W}0})\times t-1\times 100,$$ ...
The formula used for this calculation is the same as that used in the GO analysis. Here, N is the number of genes with a KEGG annotation, n is the number of DEGs in N, M is the number of genes annotated to specific pathways, and m is the number of DEGs in M. The pathways with...
Molecular formula and properties of epoxy resin Full size imageIn recent years, polymer composites have been widely used in the field of electronic devices, including central processing units, high-integrated memory chips, batteries, displays and electronic packaging materials for their excellent adhesive...
The molar mass of a compound is {eq}92 \ g / mol {/eq}. What is the molecular formula for a sample containing {eq}0.606 \ g {/eq} nitrogen and {eq}1.390 \ g {/eq} oxygen? Molecular formula The molecular formula is the ...
where Ii is the probe current in the saturated ion density (highly negative) regime, VP is the applied probe potential, A is the area of the probe, Ni is the ion density, and mi is the ion mass. The square of the relative ion density, Ni2 was determined from the slope of the line...
6-12. Lattice diffusion is virtually completely halted, but the mass transport that does occur is concentrated in grain boundaries. Though diminished, the amount of diffusion may still be sufficient to cause damage. This is why short-circuit mass transport at low temperatures is viewed as a ...
