Resistance and Resilience of Lotic Algal Communities: Importance of Disturbance Timing and Current
We examined effects of disturbance timing on resistance and resilience of epilithic algal communities growing in fast(29 cm/s) and slow(1 2 cm/s) current outdoor experimental stream channels in Kentucky, USA that were either left undisturbed (control) over 33 d following a simulated spate, or were subjected to an additional spate after either 9, 18, 27, or 33 d. On day 33, all channels were sub...
متن کاملthe efficacy of residual chlorine content on the control of legionella spp. in hospital water systems.
outbreaks of legionellosis may be a side effect of institution-water treatment. however, the long-term outcomes and the predictive factors of legionella prevalence in such systems have still not been fully studied. this study was therefore conducted to investigate the prevalence of legionella spp. and to evaluate the role of bacteriological water quality parameters on its prevalence and removal...
متن کاملInteraction between local hydrodynamics and algal community in epilithic biofilm.
Interactions between epilithic biofilm and local hydrodynamics were investigated in an experimental flume. Epilithic biofilm from a natural river was grown over a 41-day period in three sections with different flow velocities (0.10, 0.25 and 0.40 m s(-1) noted LV, IV and HV respectively). Friction velocities u* and boundary layer parameters were inferred from PIV measurement in the three sectio...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
