Remotely sensed assessment of dredging impacts on water turbidity is straightforward when turbidity plumes show up in clear water. However, it is more complicated in turbid waters as the spatial or temporal changes in turbidity might be of natural origin. The plausibility of attributing turbidity patterns to dredging activities would be greatly enhanced when demonstrating association between dr...

2014 Turbidity measurements at high pressures have been performed in the isotropic phases of MBBA, EBBA, and CBNA. In all cases an increase of the value of Tc 2014 T* with pressure is observed. However, rather unusual behavior is found for the magnitude of the turbidity at the isotropic-nematic transition : in MBBA this magnitude decreases with increasing pressure, in the homologous neighbor EB...

When an empyema with an exclusively lymphocytic cell content assumes a ‘pale creamy’ appearance, there is a possibility that the empyema has evolved into a pseudochylothorax. Otherwise, in the absence of either pseudochylothorax or chylothorax, a tuberculous pleural effusion with a >90% content of lymphocytes would be expected to have a serous instead of a pale creamy appearance, even when the ...

In this study, the treatability of rose processing wastewater was investigated by using electrocoagulation (EC) methods compared to classical chemical (CC) and Fenton application (FA) processes. High chemical oxygen demand (COD) and dissolved solids contents were detected in the wastewater. Among these treatment applications, it was found that the EC unit is the most effective treatment techniq...

Environmental context The molecular organisation of humic substances is key to understanding various natural and engineered processes, such as metal speciation bioavailability. Two main models have been proposed: polymeric supramolecular organisation. A physicochemical approach, based on the interaction acid with increasing amounts cationic surfactants, leads a sequence structures that provides...

By identifying fragments of DNA in the environment, eDNA approaches present a promising tool for monitoring biodiversity cost-effective way. This is particularly pertinent countries where traditional morphological has been sparse. The first step to realising potential develop methodologies that are adapted local conditions. Here, we test field and laboratory protocols (aqueous sediment samples)...

Eutrophication is a large problem in many marine and brackish-water areas. One of the consequences is algae-induced turbidity affecting visually feeding organisms, and behavioural changes of fish and other animals are common in turbid water. The aim of this study was to compare the performance of larval pike Esox lucius in turbid and clear water. We experimentally studied habitat choice, prey a...

Turbidity regimes vary dramatically among small streams in north coastal California. In an analysis of turbidity data from 27 small streams in the region, turbidity at the 10-percent exceedence level ranged from 3 to 116 formazin nephelometric units (FNU) for the 2005 wet season, translating to 1.7 to 65 days above an oft-cited biological threshold of 25 FNU. Watersheds draining to the streams ...
