A swinging arm type of frame height sensor was designed to measure the distance variation between the soil surface and the frame of a sensor system developed for the online measurement (tractor-based continuous measurement) of the spatial variation in soil compaction.
Several measures were adopted to reduce the effects of variation in the degree of soil compaction across pots and also other sources of variation on the waterlogging conditions.
The two-start super-coiled model, or twisted ribbon [10] predicts a linear variation of the compaction with the NRL.
That said, natural variation in chromatin compaction clearly does exist, at least in the Cvi accession (Tessodori, 2009) and we have mentioned the possibility.
Overall, considerable variation was observed between the scaling exponents for the 12 viewpoints along the + D Bl 6 chromosome, in agreement with observed qualitative variation in local compaction in Hi-C data heatmaps [ 18, 28].
Individual ES cells exhibit a relatively narrow variation in chromatin compaction, whereas primary mouse embryonic fibroblasts (PMEF) show broad distributions.
A semi-analytical model was developed for the conversion of the voltage applied to the hydraulic subsystem of an agricultural tractor to the depth under the soil surface of an attached cutting tool (subsoiler) for online measurement of spatial variation in soil compaction.
The compaction-related variation in the solid-part conductivities is large [21 550 W/(m K) and 10 230 kS/m], due to the preferred orientation variation.
The CMS was able to show some inconsistencies in the compaction process such as unequal compaction converge across the mat, non-uniform compaction effort and temperature, and delay in compaction after placement of asphalt mixtures.
In the attempt to optimise the powder metallurgy technique, variations in slurry concentration, compaction pressure and sintering temperature were investigated.
