"People change over time.
Steel corrosion has been studied in solutions containing various concentrations of Na2CO3/NaHCO3, Na2SO4 and NaCl to simulate an anticipated change in environment from carbonate-dominated to chloride-dominated groundwater composition over time.
The results also showed that MK replacement proved to be the most significant variable affecting the chloride permeability, decline of permeability over time, and the service life of the tested mixtures.
Blood urea nitrogen, calcium, sodium, potassium and chloride did not significantly change over time or between dog skill levels, P>0.05.
The chloride concentration of the surrounding environment varies over time.
Chloride ingress into concrete is a complex mechanism that could be influenced by the following circumstances: The chloride concentration of the surrounding environment varies over time.
It will oxidize over time to form toxic nitrosyl chloride, nitrogen dioxide and chlorine gases.
This study also confirms that the chloride diffusion coefficient increases with temperature and decreases over time.
Over time, sodium, calcium, magnesium and chloride build up and upset the ability of crops to draw water through their roots.
With the exception of chloride, albumin, hemoglobin, and glucose, no important shifts over time were observed (Additional file 1: Figures 4, 5, 6).
