The particle size distribution in 11 different dwellings was studied during 5-7 days, samples being taken every 15 min. Large variation in the aerosol concentration has been found. Also the size distribution of the aerosol varies depending on the level of activity in the home, e.g. smoking and cooking. The average area median diameter found in the dwellings was 0.2 ,am. A technique for the measure
The relationship between a percept-genetic measurement of creativity and other tests of creativity was investigated. The participants were elementary school children. The relation between self-image and three different creativity measures was also studied. A creative fluency test, a questionnaire about creative activities and a percept-genetic creativity test were used. A self-image inventory meas

Wear in forming tools and contact problems between sheet-metal and tool-material are common problems in manufacturing industries and sheet-metal-parts production. In this paper recent tool material experiences are presented. Quantitative determination of wear has been performed using micro hardness indentions made on the tool surface prior to pressings and thereafter measured. Wear tests are perfo
Detecting and sorting spikes in extracellular neural recordings are common procedures in assessing the activity of individual neurons. In chronic recordings, passive electrode movements introduce changes in the shape of detected spike waveforms, and may thus lead to problems with identification and tracking of spikes recorded at separate instances in time, which is an important step in long-term m
Studies on the emergence of the picture sign in small children Pictures take part in every day life for as well adults as for children. In interaction with children, pictures are often used to facilitate communication, but the child does not understand pictures as adults do; that is as signs. In my studies I try to approach an understanding of the child’s emergence of the picture sign. Empirical
This chapter singles out three areas of possible future research, where psychology in collaboration with other social science disciplines may make important contributions: (1) diplomatic signaling, (2) diplomatic culture, and (3) interaction dynamics.
