An Innovative Index for Evaluating Water Quality in Streams
A water quality index expressed as a single number is developed to describe overall water quality conditions using multiple water quality variables. The index consists of water quality variables:Expand

Conversion of trichloroacetic acid to dichloroacetic acid in biological samples.
Trichloroethylene (TCE) has been identified as an environmental contaminant in groundwater. Trichloroacetic acid (TCA), dichloroacetic acid (DCA), chloral hydrate (CH), trichloroethanol (TCOH), andExpand

A sensor network for high frequency estimation of water quality constituent fluxes using surrogates
We describe the observing infrastructure required to make high frequency estimates of water quality constituent fluxes based on surrogate data at multiple sites within an environmental observatory. Expand

Optimization of anaerobic hydrogen and methane production from dairy processing waste using a two-stage digestion in induced bed reactors (IBR)
Abstract This study investigated the effects of pH, temperature and hydraulic retention time (HRT) and organic loading rate (OLR) on hydrogen production from dairy processing waste (DPW) inExpand

Stability studies on the cyanobacterial nicotinic alkaloid anatoxin-A.
Anatoxin-a (ANTX-a) is a potent nicotinic cholinergic bicyclic secondary amine produced by some toxigenic strains of Anabaena spp. cyanobacteria (LD50 = 0.20-0.25 mg/kg i.p., mouse). Studies wereExpand

Kinetics of chloral hydrate and its metabolites in male human volunteers.
Chloral hydrate (CH) is a short-lived intermediate in the metabolism of trichloroethylene (TRI). TRI, CH, and two common metabolites, trichloroacetic acid (TCA) and dichloroacetic acid (DCA) haveExpand

Influence of sampling frequency on estimation of annual total phosphorus and total suspended solids loads
The determination of sediment and nutrient loads is typically based on the collection and analysis of grab samples. The frequency and regularity of traditional sampling may not provide representationExpand
