Radiation therapy (RT) utilizes the harmfulness of ionizing radiation for good, with the goal of destroying cancer cells without damaging too much healthy tissue. Dosimetry is always needed to achieve this goal. Dosimetry ...

Quantum theory is a particularly important instance of an operational theory.By looking at quantum theory from the perspective of more abstract operational framework one is able to study its properties in a wider context. ...

Coronal Mass Ejections (CMEs) are large-scale releases of hot plasma, to which the magnetic field is frozen-in. If the CMEs are faster than the local magnetosonic velocity in the solar wind, they create shock waves as they ...

This dissertation investigates the phenomenon of resistive switching (RS) in lowbandwidth mixed-valence perovskite manganite oxides. In particular, the compounds Pr0.6Ca0.4MnO3 and Gd1−xCaxMnO3 with x between 0 and 1 are ...

Solar energetic particles (SEPs) are an important component of space weather. They pose a serious radiation hazard to electronic equipment and biological organisms in space. They are produced in explosive events such as ...

Solar energetic particles (SEPs) and geomagnetic storms related to coronal mass ejections (CMEs) are a major research topic in solar-terrestrial and geospace physics. Solar energetic particles and coronal mass ejections ...

Two decades ago, the first experiments with a novel optical microphone using a small silicon cantilever as its sensing element were conducted at the University of Turku. In retrospect, those experiments revealed the potential ...

Particle decay processes have deep and profound implications in cosmology and especially on various early universe particle processes. Common decay rates, which may be experimentally verifed e.g., in particle accelerators, ...

High temperature YBa2Cu3Oz_6+xsuperconducting films are deposited on top of differently fashioned buffered metals to enhance the critical current density and its isotropy for coated conductor applications. The ...
