MIT's microrocket has reached 85, and its builders estimate a potential ratio more than 10 times that-more than enough to launch a satellite into space.
We estimated the spawning potential ratio (SPR) and fishery metrics (e.g., angler catch) across a range of minimum length limits and stocking rates.
A numerical example is given to show the effects of mass-reservoir chemical potential ratio, mass transfer coefficient ratio, mass leakage coefficient and internal irreversible parameter on the power output versus the efficiency characteristic of the cycle.
Per-recruit analysts of African tropical fish mostly applied deterministic and sex-aggregated length based Beverton Holt per-recruit models, but rarely examined the spawning biomass per-recruit (SBPR), spawning potential ratio (SPR), size-limit regulations, and stock recruit steepness (h).
Two effects which influence the course of the problem are considered: a flux induced velocity, referred to as the Stefan-Nusselt effect, characterized by a parameter called the potential ratio and a velocity due to the density difference between the phases, superimposed on the Stefan-Nusselt velocity, and characterized by a parameter called the density ratio.
We focused in this work on the bulk neutralizing potential ratio (NPR), which is defined as the ratio of the content of non-acid-generating minerals (typically reactive carbonates such as calcite) to the content of potentially acid-generating minerals (typically sulfides such as pyrite).
The CZTSSe samples exhibit a lower positive potential ratio of 66% at the GBs and also a lower negative potential ratio of 30% at the IGs.
Furthermore, our group reported the presence of the positive potential ratio at the GBs and a negative potential ratio at the IGs in CZTSSe thin-film, and these are closely related to device properties, especially to the J SC.
Higher positive potential ratio at GBs and lower negative potential ratio at IGs are exhibited in CZTSSe thin-film with NaF. Figure 6(a) displays the schematics of a band diagram near the GBs in the CZTSSe thin-films, and Figure 6(b) shows the CZTSSe thin-films with a 30 nm NaF layer.
