The study highlights the dynamics and morphological characteristics of the Genus Planktoniella Schutt. The two available species P. sol (Wallich) Schutt. and P. blanda (Schmidt) Syvertsen and Hasle are important components of the phytoplankton assemblage in the estuarine system of Indian Sundarbans and also marine systems elsewhere. The sampling sites for the purpose of this study include four ...

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 ...

The effects of temperature on the assembly of collagen fibrils were examined in a system in which collagen monomers are generated de novo and in a physiological buffer by specific enzymic cleavage of type I pC-collagen, an intermediate in the normal processing of type I procollagen to type I collagen. Increasing the temperature of the reaction in the range of 29-35 degrees C decreased the turbi...

In this study, coagulation performance by using biological flocculants (BFs; produced from strain Bacillus sp. F6) for turbidity removal was investigated. The results demonstrated that BFs were able to eliminate turbidity from kaolin clay solution over a wide dosage range ( DR = 6–20 mg L ). The removal efficiency with BFs reached 86 % on average, lower than 95 % with Al2(SO4)3 ( Al = 6.5 mg L ...

Officials with the Long Island Sound Study (LISS) are presently reviewing the suite of indicators used to assess and report on Long Island Sound's ecological health and the programmatic success of the LISS. As part of this evaluation, managers seek to determine whether there are environmental variables that offer valuable information on ecosystem condition but that have not historically been tr...

Since the errors made in estimating distance under water are dependent on the degree of water turbidity, improvement through training in one body of water will not transfer to another body of water if there is a large difference in turbidity. This experiment demonstrated that the transfer problem can be overcome by training divers under different turbidity conditions so that they learn to tailo...

Diquat is the only herbicide registered in New Zealand for the control of submerged invasive weeds such as hornwort or coontail ( Ceratophyllum demersum L) . However, under turbid conditions, binding to clay and charged particles in the water may deactivate diquat. To determine whether endothall achieved better control of Coontail under turbid conditions, both diquat and endothall were applied ...

Background. Traditional Chinese medicine (TCM) has long been used to treat chronic atrophic gastritis (CAG). The aim of the present study was to evaluate the TCM syndrome characteristics of CAG and its core pathogenesis so as to promote optimization of treatment strategies. Methods. This study was based on a participant survey conducted in 4 hospitals in China. Patients diagnosed with CAG were ...
