[Special souvenirs after a trip to the tropics - the diagnosis of tissue helminths].

A case history after a trip to a tropical country documents the diagnostic tools (parasitology, PCR, serology) to detect a tissue helminth infection.

Competing reactions of secondary alcohols with sodium hypochlorite promoted by phase-transfer catalysis.

With aqueous hypochlorite and a phase transfer catalyst, secondary alcohols undergo hitherto unreported free radical reactions that compete with and effectively limit traditional ketone syntheses. Product mixture profiles are determined by reactant ratios, organic cosolvent, and availability of oxygen to the system. Under argon, over half of substrate alcohols, PhCH(OH)R, are converted to benzaldehyde and free radical products through beta-scission of intermediate alkyl hypochlorites.

An intercomparison of whole-body counters at participating region III nuclear power plants.

Seventeen Region III nuclear stations originated and participated in an intercomparison study of their whole body counting procedures using the same calibration standard. The first phase of the study involved transporting a phantom containing four reactor-produced radionuclides and 40K to each plant. The plant staff were asked to follow all procedures applicable for a human subject including routine and investigative counts, if necessary, and to provide a printout of the results to the project investigators.
