A versatile spectrograph platform has been installed by University College London at the Adventdalen Observatory in Svalbard. The platform was primarily built to support the Southampton University study of proton aurora and smallscale auroral features. It has successfully recorded the spectral profile of the Doppler broadened H-beta emission line (486.1 nm) and observed the predicted red shifte...

Under continuous-light regimen Coprinus lagopus can enter and complete meiosis at 25 C, but is unable to do so at 35 C. The temperature-sensitive and the dark-dependent period is 10 hr before karyogamy. It is conjectured that the basidia are programmed for the initiation of meiosis during that 10-hr period.

Ss who receive information about a person's traits and behaviors in a social context are likely to focus their attention on the pragmatic implications of this information (i.e., why the information was conveyed). To examine this hypothesis, Ss listened to a taped conversation in which a male target (T) and another speaker (O) exchanged anecdotal accounts of T's behavior. Ss typically used O's t...

After hearing the punch line of the joke, the teenager falls to the floor, almost as if actually punched. She remains there, completely unable to move. She hears her parents reassure her friends that they need not worry about her because she will be all right in a few minutes. She is embarrassed and frustrated as the episode continues, and her friends begin to leave. They bid her goodbye, but s...

This report describes activity at a workshop on New Measurement Technology for Polymer Processing which was held at the National Institute of Standards and Technology on December 3-4,1990. The workshop was attended by 19 industry scientists and engineers from polymer processing and instrumentation manufacturing companies. The objective was to seek industry responses to the question: what in-lin...

Emotional stimuli often attract attention, but at what cost to the processing of other stimuli? Given the potential costs, to what degree can people override emotion-based attentional biases? In Experiment 1, participants searched for a single target within a rapid serial visual presentation of pictures; an irrelevant, emotionally negative or neutral picture preceded the target by either two or...

The transition from vegetative to reproductive development establishes new growth patterns required for flowering. This switch is controlled by environmental and/or intrinsic developmental cues that converge at the shoot apical meristem (SAM). During this developmental transition, floral inductive signals cause the vegetative meristem to undergo morphological changes that are essential for flow...
