In this paper, effects of LENS input deposition variables (laser power, deposition head scanning speed, and powder feeding rate) on deposition quality (such as layer geometry, surface roughness, flatness, powder efficiency, and microhardness) were studied.
The equilibrium is controlled by the balance between organic input (deposition of organic matter at the sediment surface) and the intensity of bioturbation.
Depositional interpretation of sediment infill indicates that in the South Caspian Basin, as in other closed basins with high terrigineous input, basinal deposition is from turbidity currents and slumps generated from large shelf-edge deltas.
Especially the low Fe values (<0.5%) in subunits II and III indicate reduced terrigenous input during deposition of these sediments.
The assessment was made with the SMART2 model, a simple one-layer model including geochemical buffer processes, element cycling by litterfall, mineralisation and uptake, nitrogen transformation processes and element input through deposition, weathering and upward seepage.
Forest ecosystems are often found on acid soils where calcium availability depends on two main inputs (atmospheric deposition and the weathering of soil minerals) and on the biological cycling of nutrients.
The strong correlation between atmospheric CO2 levels (from Antarctic ice cores) and community dynamics is somewhat surprising taking into account that, in addition to changes in global climate, the fossil diatom assemblages analyzed here were influenced by local determinants such as regional current systems, terrestrial nutrient inputs, atmospheric deposition, physical mixing, etc [31], [45].
Pollutants can enter soils from a wide range of sources including, among other means, agricultural inputs, atmospheric deposition, flood and irrigation water, accidental spills, inappropriate solid, liquid and hazardous waste disposal, industrial activities.
Beyond the input of acidity, deposition of NH4+ and NO3- fertilizes ecosystems by providing a source of directly assimilable nitrogen ( section 6.3 ).
This was done by comparing the input of atmospheric deposition of polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) and PCBs with the amounts exported to surface waters.
Deposition input power of 75 to 150 W was used in fabricating TaN layers with various impingement energies for different structures.
