The traditional technique for processing of reactor-irradiated 186 W-enriched tungsten oxide (WO 3 ) targets involves formation of 188 W-sodium tungstate solutions by target dissolution in 0.1 M NaOH. Following long irradiations (> 21 days) in the OR

A simple method using an alumina SepPak ® has been developed to determine the breakthrough levels of 188 W from 188 W/ 188 Re generator systems. Detection of low levels of 188 W in the presence of high levels of 188 Re (155 keV, 15%) by traditional

The ``IQNP`` agent is an antagonist for the cholinergic-muscarinic receptor. Since the IQNP molecule has two asymmetric centers and either cis or trans isomerism of the vinyl iodide, there are eight possible isomeric combinations. In this report, the
