Six human 5S rRNA genes and gene variants and one pseudogene have been sequenced. The six genes/variants were transcribed in a HeLa cell extract with about equal efficiency. Three genes contain the Sp1 binding sequence GGGCGG in position -43 to -38 and three genes contain the Sp1 like sequence GGGCCG in this position. The six genes contain furthermore one(More)
One of the most important aspects of usability is consistency in user interfaces. Consistency should apply both within the individual application and across complete computer systems and even across product families. Practical methods for coordinating user interface design are not well known, however. To remedy this situation, a workshop on <i>Coordinating(More)
One of the basic usability testing techniques the HCI community draws on, and which stands out as unique, is thinking aloud. We introduce the many names, uses and modifications of the classical think aloud technique, and ask the rhetorical question: What do researchers think they get when they ask people to think aloud? We answer it by discussing the(More)
A major fraction of the human 5S rRNA genes has previously been assigned to chromosome region 1q42.11-->q42.13 (Sørensen et al., 1991). Through in situ hybridization of different tritiated probes to metaphase spreads, we have demonstrated that a minor fraction of the 5S rRNA genes is localized at band 1q31. This fraction amounts to 25-30% of the genes found(More)
The crystal structure of a PNA duplex reveals both a right- and a left-handed helix in the unit cell. The helices are wide (28A), large pitched (18bp) with the base pairs perpendicular to the helix axis, thereby demonstrating that PNA besides adapting to oligonucleotide partners also has a unique structure by itself.
Barley (Hordeum vulgare L.) produces a leucine-derived cyanogenic β-d-glucoside, epiheterodendrin that accumulates specifically in leaf epidermis. Barley leaves are not cyanogenic, i.e. they do not possess the ability to release hydrogen cyanide, because they lack a cyanide releasing β-d-glucosidase. Cyanogenesis was reconstituted in barley leaf epidermal(More)
The paper describes a large European R&D-project on Multimedia And Network In Co-operative Research And Learning (MANICORAL) from point of view of the participating HCI-researchers. The project developed the methodology of Dialogue Design, drawing on two sources: Participatory Design and Dialogue Research. Action Research is understood as the historical(More)
Cultural differences in cognitive processes and cognitive tools have been extensively documented. Design and use of culturally sensitive interfaces have been in demand in HCI for sometime. In this study the method of stimulated retrospective verbalization which is called here as Mind Tape study, has been used to capture cognitive differences of Danish and(More)
