1. När fysik blir lärområde i förskolan
Sammanfattning : This dissertation includes four separate empirical studies, and is directed towards what happens when physics becomes a learning area in preschool. It is about children and preschool teachers exploring and working with physical phenomena such as friction, sound, floating and sinking. LÄS MER
2. MRI Perfusion Measurements using Magnetic Susceptibility Effects: : Calibration Approaches and Contrast Agent Quantification
Sammanfattning : Exchange of oxygen and nutrients between blood and tissue occurs at the capillary level of the blood system. The blood volume flow rate in the capillaries is often referred to as perfusion, and knowledge about perfusion provides important information about the function and viability of the tissue, for example, in patients with ischaemic stroke, cancer, and neurodegenerative diseases.
