The frequency at which beetles surface to replenish the bubble is determined both by oxygen demand and by the capacity of the air store to uptake oxygen from the surrounding water via diffusion. However, little is known of how changes in water temperature and dissolved oxygen will affect ...

摘要: The freshwater cladoceran Moina macrocopa showed high tolerance to hypoxia, but high temperature shortened its lifespan and reduced its reproductive performance. The 48-h LC50 values of Cr, Cu, Ni and Zn for M. macrocopa were not significantly affected by temperature and hypoxia.关键词:...

Effect of temperature and dissolved oxygen concentration on nitrification rate were investigated with enrichment cultures of nitrifying bacteria. Values of specific nitrite oxidation rate in the absence of ammonia were 2.9-12 times higher than maximum specific ammonia oxidation rates at the same temperatur...
At low temperature, the dissolved oxygen concentration only affected the attack behavior of the Al-Zn-In and Al-Zn-In-Cd anodes but had little influence on the attack behavior of the Al-Zn-In-Mg-Ti anode. 展开 关键词: Aluminium Temperature dissolved oxygen SEM Cathodic protection ...

The developed models can be used to predict mean, maximum and minimum water temperatures and dissolved oxygen at the monthly, weekly and daily time scales. A nonlinear logistic model is found to best represent the S-shaped relationship between water temperature at the real-time stations and air ...
