1. The left half represents the traditional karst process, which is mainly controlled by hydrological processes, while the right half represents the biogeochemical and ecological processes, which are controlled by photosynthesis/respiration. Due to the involvement of short-time scale biological processes,...
Using structural equation models analysis, we find that an increase in carbon input from the crops accelerated fungal succession and enhanced microbial growth efficiencies, leading to a progressive increase of microbially-derived carbon contributions to SOC formation and accrual at decadal timescales under...
In equation (4), SHt,TRU refers to the share of hydrogen fuel cell trucks; SHt,RAI refers to the share of railways that using hydrogen; SHt,SHI refers to the share of shipping that uses hydrogen; DISp,t is the distance travelled in year t by vehicle type p; LOADp,t is the load ...
LCA is defined as “the compilation and evaluation of the inputs, outputs and potential environmental impacts of a product system throughout its life cycle”. It
(e.g. annual), and is calculated as the difference between photosynthesis and autotrophic respiration within the given year. NPP operates as the primary input flow parameter for the LUCAS model. Global NPP is estimated at 60 Gt C year−1, which is about half of the estimated gross primary...
Once a material has a low ICE, even if in a half cell of laboratory research, it always indicates that the material will lead to low energy density and cycle life, and the prospect of practical application will also be lessened. Therefore, a high ICE is a highly desirable parameter in ...
14, it can be noted a linear decrease of MNP concentration with time, indicating that the biodegradation process obeys to the 0-order kinetics with a rate constant (22 °C) of 10.4 mg L−1 h−1 and a half-life time of 4.5 h. Assuming fungi’s ability to direct mineralization of ...
The energy consumption of the two cold regeneration processes accounts for a larger proportion of the energy consumption in the raw material production stage, which accounts for half of the overall energy consumption of the regeneration process. The energy consumption of each asphalt pavement ...
Once tmin was known, Equation (1) was considered to represent the water infiltration into the soil from there onwards, and Ks can be assessed from its slope. 2.8. Soil Carbon Dioxide Emission Rate Polyvinyl chloride (PVC) collars of 10 and 4.5 cm in, respectively, inner radius (r) and ...
We replace production with the MUEEI as the denominator in the equation. Normalization by the index helps size the emission-reduction opportunity at any upstream asset relative to the lowest emitters and traces back to the areas to address across structural and operational...
