Nucleation and subsequent growth of particles was studied in the CLOUD7 chamber experiment at Cern. Experiments were performed in varying concentrations of sulphuric acid, ammonia, dimethylamine and α-pinene, and using both ozone and hydroxyl radicals as oxidizers. Particle growth rates were determined at size ranges <1.5 nm, 1.5–3 nm, and >3nm. Comparison of the growth to the amount oxidized o...

Analysis of the marking fluid of two tigers (one Bengal and one Sumatran) by GC using an amine-specific column and a nitrogen-specific detector has shown the presence of the following amines: ammonia, methylamine, dimethylamine, trimethylamine, triethylamine, propylamine, and butane-1,4-diamine (putrescine). In contrast to previously published reports, we were unable to detect 2-phenylethylamin...

OBJECTIVE Some neuropeptides and monoaminergic neurotransmitters may affect hypothalamic feeding centres, sympathetic activity and thermogenesis. Sibutramine (BTS54524; N-[1-[1(4-chloro phenyl) cyclobutyl]-3methyl N,N-dimethylamine hydrochloride monohydrate) is a new 5-HT serotonin and noradrenaline reuptake inhibitor (SNRI), antiobesity drug. The aim of this study was to evaluate the effects o...
