Phase contrast MRI segmentation using multiple cues

This paper presents a method for three-dimensional (3D) segmentation of blood vessels, using a combination of velocity data and magnitude images obtained using phase contrast MRI. In addition to standard MRI images, phase contrast MRI gives velocity information for blood and tissue. The proposed method uses a variational formulation of the segmentation problem which combines different cues; veloci

Isocyanates and amines from fires - a screening over commom materials found in buildings

Isocyanates, aminoisocyanates and amines were quantified from the combustion of 24 different materials or products typically found in buildings. Small-scale combustion experiments were conducted in the cone calorimeter, where generally well-ventilated combustion conditions are attained. Measurements were further made in two different full-scale experiments. Isocyanates and amino-compounds were sa

Magnetomotive Ultrasound Imaging Of Rat Lymph Nodes In Situ: Assessment Of Imaging Parameters

Detection and removal sentinel lymph nodes (SLN) is important in the diagnosis and treatment of breast cancer and malignant melanoma. The SLN is the first regional lymph node draining the cancer tumor and if the cancer has spread it is most likely to find cancer cells in the SLN. In this study we have been able to detect multimodal superparamagnetic iron oxide nanoparticles (SPIO-NP) in rat SLNs i

Collaborative Decision Making (CDM) - A Pilot Study Exploring Participation and Empowerment Before Implementing New Technology and Work Procedures

The pressure on European air-traffic logistics increases, both at the airports and in the sky, as the passenger rate increases. Handling airborne aircraft is becoming more rationalized as an effect of sophisticated technology and lower separation-minima. Technological and legal development at airports is lagging behind causing delays. Airport operations might be more efficient by increasing accura

Etik, emotion och existens. Tankar krting en ny begreppshistoria.

Artikeln diskuterar nya tillämpningar av den tyska begreppshistoriska tradition som utvecklats av bl.a. Reinhart Koselleck. I fokus står nya forskningsområden rörande tillvarons problematik - områden som rör etik och moral, känslor och psykologi och existensens förutsättningar - samt hur begreppshistoria kan användas metodologiskt för att närma sig dessa ibland svårhanterade ämnen.

I antologibidraget visas att lärande, eller kanske snarare deltagande i olika former av utbildning, rättfärdigas på olika sätt beroende på om de som utbildas är barn eller vuxna. Rättfärdigandet sker genom retoriska konstruktioner av samhället som närmast kan ses som motsatser: barnens skolgång rättfärdigas genom att samhället konstrueras som en, åtminstone värdemässig, konstant; vuxnas deltagande
