Agilent is now offering a comprehensive analyser package for the target based, multiresidue screening of environmental waters on the Agilent 5977 GC/MS. This screening method uses Target Deconvolution (TD) on the MassHunter Quantitative software. It is suitable for the analysis of environmental waters as required by the Water Framework Directive (WFD 2000/60/EC). This method uses a target MS li...

In spallation neutron sources neutrons are produced when a beam of high-energy particles (e.g., I GeV protons) collides with a (watercooled) heavy metal target such as tungsten. The resulting spallation reactions produce a complex radiation environment (which differs from typical conditions at fission and fusion reactors) leading to the radiolysis of water molecules. Most water radiolysis produ...

Although the pesticides are widely used in agriculture, they, and in particular the relative residues in foodstuff, waters and atmosphere, make a remarkable social alarm and sanitary problems for the harmful effects (carcinogenic and mutagenic effects) producing on the human health. In fact, their spread in waters and atmosphere can produce undesired effects on various organisms and determine t...

The high water permeability of kidney proximal tubules is of paramount importance for isotonic reabsorption of 70% of the glomerular filtrate, and water channels have been postulated to account for the high water permeability. Target analysis following radiation inactivation was used to probe the molecular size of the water channel. Samples of brush border membranes from rat renal cortex were s...

objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
