One may begin describing the distance course “IT and Learning- rehabilitation engineering” by saying that it was a great success. Looking back, it is evident that our experience from two years of working with Internet-based teaching prior to the present course was absolutely vital to its favorable outcome. It is difficult to switch from classroom-based to Internet-based teaching. There are mechani
Recently, chemists and physicists in the Joint Working Party (JWP) have approved the new elements, but what is the significance and how can we make use of elements that exist so fleetingly?
The single muscle fiber preparation provides an excellent tool for studying the mechanical behaviour of the contractile system at sarcomere level. The present article gives an overview of studies based on intact single fibers from frog and mouse skeletal muscle. The following aspects of muscle function are treated: (1) The length-tension relationship. (2) The biphasic force-velocity relationship.
BACKGROUND: Retransfusion of the patient's own blood during surgery is used to reduce the need for allogenic blood transfusion. It has however been found that this blood contains lipid particles, which form emboli in different organs if the blood is retransfused on the arterial side. In this study, we tested whether retransfusion of blood containing lipid micro-particles on the venous side in a po
A water-repellent treatment normally works well if there are no cracks in the façade. The occurrence of cracks, however, may allow water to penetrate, resulting in significant moisture. How wide a crack may be tolerated is not known. A limit of 0,3 mm is often allowed. To illuminate this question and create a better basis for evaluating an acceptable width for a crack, this paper will present both

Abstract Objectives. To investigate whether coronary microemboli have long-term effects on left ventricular (LV) function in an experimental model. Furthermore, to determine if first-pass perfusion and late gadolinium enhancement (LGE) patterns differs between small- and large-sized microemboli. Design. Six pigs underwent left anterior descending (LAD)-coronary microembolization with small-sized (
Laser-induced fluorescence (LIF) investigations have been performed in connection with photodynamic therapy (PDT) of basal cell carcinomas and adjacent normal skin following topical application of 5-aminolaevulinic acid (ALA) in order to study the kinetics of the protoporphyrin TX (PpIX) build-up. Five superficial and 10 nodular lesions in 15 patients are included in the study. Fluorescence measur
