To determine the microbial contribution to this increased SOC storage capacity, we quantified catabolic enzyme activities, metabolic quotients of native SOC (bulk soil) and rhizodeposition (13C content), and specific enzyme activity in Control+Recent and Historical+Recent soils. Microbial biomass increase...
2. The lower dissolution rates in the over-aged state can be due to the lower solute contents in the matrix and the stronger electronic bonds of the elements in the precipitates. Also, the coarsening of the precipitates increases their stability in the over-aged state, thus decreasing the ...
What elements from the periodic table must we have to sustain life, here on Earth? Is there a way to determine if two atoms will form ions or a covalent bond when they react? An atom is in its most stable state when A) the numbe...
i.e. on the neutron rich side of the line of stability, half-life data are generally better known and the respective number ofT1/2determinations is larger. This is especially true for isotopes of the actinide series, where large effort has been put to improve decay data for the nuclear...
natural anisaldehyde with natural acetone produced by fermentation. Anisylidene acetone is then hydrogenated to obtain anisine acetone. Finally, the anisine acetone is demethylated to obtain natural Raspberry Ketone. The method of measuring isotope 14C is used to determine that its naturalness is over...
To determine how the four ant species influence carbon fixation and water relations in these acacias, Milligan and his colleagues set up a five-year ant-removal experiment between 2013-2018. They found 48 matched pairs of trees that harbored each ant species (12 pairs of trees per ant species...
To determine the potential differences in C stability per severity level, future research should target the relationship between the various respiration components and (manipulated) soil temperature under several severity levels over time (long and short timescales). 3.1.2. Time after fire The required...
Isotope dilution methods were used to determine MeHg concentrations in sediments and waters. Briefly, an isotopic amendment of enriched Hg isotope was added to the sediment prior to distillation pretreatment (U.S. EPA, 2001). Distillates were then derivatized with sodium tetraethylborate and analyzed...
Furthermore, going beyond the doping compensation threshold associated to Fermi level pinning triggers observable changes in the thermal conductivity. This informs design considerations on the doping of BAs, and it also suggests a direct way to determine the onset of compensation doping in experimental...
2. Explain trends in the relative stability of nuclei. What is the difference between nuclear fission and nuclear fusion? What are the significances of them both? Determine whether the following nuclear reaction is fusion or fission. Explain your answer. ^{229}_{90}Th \to ^{225} _{88}R...
