A comparative analysis of global and local processing of hierarchical visual stimuli in young children (Homo sapiens) and monkeys (Cebus apella).
Results obtained with preschool children (Homo sapiens) were compared with results previously obtained from capuchin monkeys (Cebus apella) in matching-to-sample tasks featuring hierarchical visualExpand

Synthesis and pharmacological activity of thiohexital enantiomers.
(S)-(+)- and (R)-(-)-5-Allyl-5-(1-methyl-2-pentynyl)-2-thiobarbituric acid (1, thiohexital) were prepared. The anesthetic activity (loss of righting reflex) and acute toxicity of the optically pureExpand

Radiation induced polymerization of dimethylcyclosiloxanes in the liquid state: 2. Polymerization kinetics of D3, D4 and D5 and the distribution of products
Abstract The rates of radiation induced polymerization in bulk of the cyclodimethylsiloxanes, D3, D4 and D5 have been determined under super-dried conditions. Drying was achieved by using repeatedExpand

Radiation-induced polymerization of dimethylcyclosiloxanes in the liquid state: I. Influence of drying and nature of the propagation mechanism
Abstract The radiation (cobalt 60 γ)-induced polymerization of octamethylcyclotetrasiloxane D 4 and decamethyl-cyclopentasiloxane D 5 has been studied in the liquid state. Progressive drying of theExpand
