The results show that the dissolving rates of N and P from two kinds of culturation newborn remains and their TN/TP and IP/TP ratios are varied in a greater range with the lapse of time, and the general changing patterns of the two newborn remains are similar.
1. The effects of temperature change on L. vannamei showed that the frequency of movement (FOM) and the swimming-walking speed (SWS) in all temperature treatments had no significant differences in experiment I , but in experiment II FOM and SWS increased with the temperature changing to 36℃ and decreased significantly with the temperature changing to 18 ℃, respectively.
A sign-changing solution for elliptic equation with sublinear term at origin
It is proved that the semilinear elliptic problem with zero boundary value -Δu=λu-|u|q-1u has a changing sign solution, as q∈(0,1) and λ>amp;gt;λ2, where λ2 is the second eigenvalue of the operator -Δ in the space H01(Ω).
CdSe nanocrystals of different sizes could be obtained by simply changing the solvent.
Spherical, spherical-like, and hexagonal silver nanoparticles can be obtained by changing the reductants.
Results showed that the morphology of the ZrWMoO8 particles can be simply adjusted by changing the gelling agents, and the thermal expansion coefficients of cubic ZrWMoO8 prepared in HCl solution are -3.84 × 10-6 K-1 from 100°C to 700°C.
