BACKGROUND, AIM, AND SCOPE Fishery wastewater treatment can be compromised due to seasonal production. The use of sequencing batch reactors is not completely successful, despite flexibility being one of the principal advantages. Most research on activated sludge is performed using synthetic wastewater to ensure a stable and constant feed. The current work compared biomass morphology and settlin...

It can be shown from bedform stability diagrams, that each turbidity current, regardless of whether its density is low or high, or whether its history is simple (e.g., surging flow) or complex (e.g., sustained flow), should pass through a final waning phase in which flow conditions are prone to bedform development. Yet, many thick deep-marine sandstones of supposed turbidity-current origin are ...

[1] Levees are the primary elements of self-formed submarine channels, yet little is know about their morphodynamics. We present field observations of static levee morphology and stratigraphy in addition to laboratory experiments that link levee morphodynamics to turbidity current flow properties. These observations are used to motivate a levee growth model. Using a three-dimensional seismic vo...

An understanding of sediment transport processes and resultant concentration dynamics in estuaries is of great importance to engineering design awareness and the management of these environments. Predictive modelling approaches provide an opportunity to investigate and address potential system responses to nominated events, changes, or conditions of interest, often on high temporal and spatial ...

Laboratory experiments were conducted to determine how larval and juvenile yellow perch Perca flavescens respond to changes in prey density when exposed to different levels and types of turbidity (phytoplanktonic or sedimentary). Across prey densities, consumption by P. flavescens tended to be less in phytoplanktonic turbidity compared with sedimentary turbidity. For larvae, this effect was dep...

We compared the effects of specimen turbidity and glycerol concentration on nine enzymatic methods for triglyceride measurement. We assayed 51 specimens with triglyceride concentrations of 0.85-8.21 mmol/L (75-727 mg/dL) and turbidity at 420 nm equivalent to > or = 0.1 mmol/L (8.8 mg/dL) triglyceride (measured as part of our comparison method). The data were analyzed by multiple regression, whi...

The objective of this paper is to study the turbidity behavior in an Amazon Floodplain Lake. Observations of turbidity provide quantitative information about water quality conditions. However, the number of available in situ measurements of water quality characteristics is usually limited, especially temporal series variables and synoptic coverage of extensive water body. In order to contribute...

In tuna farming, turbidity measurement is highly important since one of the cause of death of tuna is a choking death due to muddy water. In this paper, we consider to use visible light communication modules for estimation of turbidity in underwater environments. If these modules can be used as turbidity meters, additional introduction of dedicated turbidity meters is not necessary. In this pap...
