During the period of breeding larvae, the change range of NO 2 - N, NH 3 N and COD in test pond water were 18.2 %～ 91.7 %, 25.0 %～ 39.3 % and 16.5 %～ 50.0 % less than that in the control pond, respectively, and no medicine was added in the test ponds, no water exchanged.

Linear programming in the foreign exchange markets
Effects of exchange rate and tariffs on an open economy of scarcity of capital
In this paper, the impact of tariffs and exchange rate on consumption and investment in an open economy of scarcity of capital is analysed.
The purpose of present work is to examine the financial problem of finding the universal reservation prices of a European call option written on exchange rate when there is proportional transaction costs of trading foreign currency in the market.
Besides the hydrophobic interaction provided by nonpolar dodecyl, DPZ also has dipolar interaction, ion-exchange or electrostatic repellent interaction provided by the free phosphonic group and amino group at different conditions.
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.
They are potential tools for the decomposition and handling of signals that, like speech or music, seem over short intervals to have well-defined frequencies that, however, change with time.
Furthermore, at low concentrations (up to 5 mM), Me2SnCl2 binds to the phosphate groups of DNA in an exothermic step and had no significant effect on double-strand DNA stability, confirmed by the fact that the Tm value did not change.
The existence of positive solutions of the nonlinear fourth order problem is studied, where a:[0,1]→R may change sign, f(0)>amp;gt;0, λ>amp;gt;0 is sufficiently small.
Particularly, it can be applied without any change to meshes of nonmanifold topology.
