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...

Our main goal is to assess the hydrodynamics of turbidity currents and mudflows and their ability to produce morphological features such as ripples, dunes, antidunes and gullies along their paths. Of particular interest is to elucidate the role played by turbidity currents on the inception of submarine channels and canyons. To this end, understanding the mechanics of sediment erosion, including...

Turbidity as a result of increased suspended sediments in coastal waters is an environmental stress of worldwide concern. Recent research on fish suggests that detrimental changes to gill structure can occur in turbid waters, with speculation that these alterations diminish fitness variables, such as growth and development, by negatively impacting the O2 uptake capacity (respiration) of fish. S...

Background & objectives: Nitrate contamination of drinking water is a common problem in many parts of the world that poses a serious threat to public health and environment. In this research, the performance of a new rotary electrocoagulation reactor model for removal of nitrate in presence or absence of turbidity has been investigated. Methods: In this study, aluminum and iron electrodes were...
