This thesis investigates educational software: computer software applications which serve to support teachers and improve learning outcomes for students. It aims to delineate the field of educational technology research as an interdisciplinary field and exemplify some of the methods used for approaching the many research questions that arise from asking what makes good educational software. The ov

Cascaded convolutional codes with conventional convolutional codes as constituent codes are powerful and attractive to use in communication systems where very low error probabilities are needed. This paper clearly demonstrates the dramatic effect the replacement of the inner convolutional encoder by an equivalent one could have on the cascaded convolutional code

This PhD thesis deals with anthropomorphic images from the Vendel and Viking Ages, their contexts and functions. The images are seen as means of communication with “effective power” or agency ("Wirkmächtigkeit"). They could have had a relationship of interaction or partial identity with what was represented, due to the fact that the Vendel and Viking Age societies were largely based on oral tradit

Kulturartikel om rasism i svensk film med anledning av en SVT1-visning av filmen "I mörkaste Småland" (1943). Särskilt stereotypiseringen av tattaren behandlas i texten.

Ambulance organisations in Sweden have introduced prehospital fast track care (PFTC) for patients with suspected hip fracture. This means that the ambulance nurse starts the pre-operative procedure otherwise implemented at the accident & emergency ward (A&E) and transports the patient directly to the radiology department instead of A&E. If the diagnosis is confirmed, the patient is tra

The (14)C-glycocholic acid and (14)C-xylose breath tests are clinically used for the diagnosis of intestinal diseases, such as bacterial overgrowth in the small intestine. The two tests have in earlier studies been thoroughly evaluated regarding their clinical value, but due to the long physical half-life of (14)C and the limited biokinetic and dosimetric data, which are available for humans, seve

BACKGROUND.: The proliferation signal inhibitor everolimus offers the potential to reduce calcineurin inhibitor (CNI) exposure and alleviate CNI-related nephrotoxicity. Randomized trials in maintenance thoracic transplant patients are lacking. METHODS.: In a 12-month, open-labeled, multicenter study, maintenance thoracic transplant patients (glomerular filtration rate >/=20 mL/min/1.73m and 1 year

Normvärdet 0,5 luftomsättningar per timme är för lågt under den varma årstiden och onödigt hög på vintern. Ventilationen bör variera med årstiden. Helst bör styrningen ske automatiskt via ånghalten i luften. Rekommendationerna i SBN och nuvarande Nybyggnadsregler om hur platta på mark bör utföras har varierat under åren. Men konsekvent har man prioriterat uttorkning av byggfukt och därmed dragit

Symptom relief through spinal cord stimulation (SCS) based on the gate-control theory and enhanced external counterpulsation (EECP) through improved coronary perfusion is two treatments in angina pectoris refractory to medication and surgery. The overall aim was to evaluate and compare the initial and longterm effects, utilization and cost of EECP compared to SCS. The effects were also compared to

Progression to metastasis is the proximal cause of most cancer-related mortality. Yet much remains to be understood about what determines the spread of tumor cells. This paper describes a novel pathway in breast cancer that regulates epithelial-to-mesenchymal transition (EMT), motility, and invasiveness. We identify two transcription factors, nuclear factor 1-C2 (NF1-C2) and Forkhead box F1 (FoxF1

Poor nonword repetition is considered as a clinical marker of specific language impairment (SLI). In children with expressive language problems, the analysis and scoring procedures are often insufficiently described. We argue for a combined analysis of segmental and suprasegmental accuracy in nonword repetition tasks as well as an appreciation of gender differences. The view is taken based on empi
