Scattering from an acoustically soft elliptic disk is treated by means of the null field approach. It is shown that in the disk limit of a general ellipsoid the relevant matrix elements have a well-defined limit, and that the formulation is attractive for numerical calculations. In a separate section the low frequency expressions of the total cross section and the far field amplitude are also deri

This article is a review of a book by the Swedish ethnologist Billy Ehn. The book gives a description and analysis of the events when four departments were integrated into one. The writing of the book resulted in a conflict that forced Ehn to resign as the dean of the newly created department. One reason for his resignation was that the staff of the department felt that they had not been properly

The role of Latin in the formation of Western Europe, especially through the Carolingian Reform and the medieval University.

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
