Basic 1D diagenetic model The basic reactive-transport diagenetic model we developed includes six components, including two solid-phase species: organic matter and CFA; and four solute components: [Ca2+], [DIC], [DIP], and [F−]. The mass balance functions for this basic model are30,31: $$frac{{partial {mathit{C}}_l}}{{partial t}} = frac{1}{phi }frac{partial }{{partial x}}left( {phi {mathrm{D}}frac{{partial C_l}}{{partial x}}} right) – frac{1}{phi […] More

Deforestation The deforestation of the planet is a fact2. Between 2000 and 2012, 2.3 million Km2 of forests around the world were cut down10 which amounts to 2 × 105 Km2 per year. At this rate all the forests would disappear approximatively in 100–200 years. Clearly it is unrealistic to imagine that the human society would start […] More

There is a clear and systematic difference in peat OM content and stoichiometry in organic soils between the four studied land use types in Switzerland. We presume that differences in OM content among land use types, as found here, mostly reflect drainage and land use effects, and are the result of long-lasting decomposition. Yet, it […] More

Electrolysis ecological floating bed design and eutrophic water In this research, the EEFBs and the traditional EFBs both had the same surface area of 1,089 m2 and were designed to compare their removal efficiencies in eutrophic waters under similar conditions. The EEFBs were made of polystyrene board 33 cm wide × 33 cm long × 5.5 cm thick. […] More

Sample collection Eighteen samples of mono-varietal Ogliarola campana EVOO were directly collected in Campania region (Southern Italy), among olive production areas ascribed to four regional PDOs (Fig. 1): Irpinia (IR, 7 samples), Colline Salernitane (CS, 4 samples), Penisola Sorrentina (PS, 5 samples) and Cilento (CI, 2 samples). The unbalanced experimental design was constrained by local and […] More

Selective carbon sources influence the end products of nitrate respiration in microbial enrichment cultures To enrich for nitrate-respiring microbial communities from samples of aquatic sediment, agricultural soil, and groundwater, we inoculated them into a medium with 20 mM sodium nitrate as the electron acceptor and 2 g/L yeast extract as the carbon source and electron donor, and we […] More
