The paper discusses the motivation for and outcome of the addition of socially oriented so called “off-task” conversational abilities to an existing “teachable agent” (TA) in an educational mathematics game. The purpose of the extension is to affect constructs known to promote learning, such as self-efficacy and engagement, as well as enhancing students’ experiences of the game. A comparison of st

The text discusses the phenomenon of modern rune carvers within the Nordic countries. The article illuminates the purposes and different meanings connected to the act of rune carving in our time. It is concluded that the shaping of identity in close relation to visions of past times is an important part of the rune carving activities of today.

Construction projects are costing too much and taking too long as a consequence of unnecessary omissions and errors in project documentation and sub-optimal coordination of design information between consultant disciplines. The theory behind BIM provides an exciting integrated solution for project information management, however in this new process further effort is required to define the content

Antibodies are important proteins participating in a number of reactions to protect us from harmful diseases. Apart from this important function, they are also useful in different technical and medical applications. This, however, relies on our possibility to produce antibodies in vitro. In the first part of my thesis a new technology called CDR shuffling was developed to create diverse and highly

Popular Abstract in Swedish Cancer är en genetisk sjukdom, som uppkommer genom ansamling av icke-letala mutationer. Dessa mutationer, som kan ske på både DNA- och kromosomnivå, ger cellen tillväxtfördelar och leder till klonal expansion av en cellpopulation som står utanför de normala tillväxtkontrollerna. Utvecklingen från normal till malign fenotyp sker stegvis, där ökad ansamling av genetiska sA series of primary and metastatic breast carcinomas obtained from female and male patients were cytogenetically analysed. Trisomy 12 was identified as a recurrent and sometimes early event in breast carcinogenesis. Also, multiple polysomies involving chromosomes 1, 5, 6, 7, 12, 16, 18, and 19 were identified as a possible pathway of progression in a subset of carcinomas. Among the male breast car

High-performance concrete slabs have been field exposed at the Traslovslage marine field station at the Swedish west coast since April 1992 as a part of the Cementa/Euroc sponsored project, "Durability of Marine Concrete Structures." The concrete slabs mounted on a floating pontoon are exposed in three exposure zones: submerged, splash, and upper splash zones. The results after two years of exposu

Popular Abstract in Swedish Alpha1-antitrypsin (AAT), som är ett cirkulerande glykoprotein, är den vanligast förekommande serinproteinashämmaren i plasman hos människa. Den ingår i gruppen av akutfasproteiner, och dess halt i plasma kan snabbt öka till koncentrationer överstigande 50 mM vid inflammation, infektion eller malign sjukdom. Då AAT fungerar som en effektiv hämmare av neutrofilelastas ocAlpha1-antitrypsin (AAT), a circulating single-chain glycoprotein is the most abundant serine proteinase inhibitor in human plasma. AAT is an acute phase protein, its levels increase rapidly to concentrations exceeding 50mM in response to inflammation, infection and malignant diseases. Since AAT is a powerful inhibitor of neutrophil elastase and proteinase 3, it is generally assumed that its physi
