Particle observations in near-earth space: Design and verification of particle instruments for CubeSat experiments
(Turun yliopisto, 2021-12-15)
This doctoral thesis presents the design, simulation, and calibration of two instruments developed to study energetic charged particles in low-Earth orbit. The near-Earth energetic charged particle populations include ...
Measurement simulability and incompatibility in quantum theory and other operational theories
(Turun yliopisto, 2021-06-17)
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. ...
Empirical modelling of solar energetic particles
(Turun yliopisto, 2021-06-28)
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 ...
Low bandwidth manganite (Gd, Ca)MnO3 for future memristor devices
(Turun yliopisto, 2022-05-21)
The feasibility of the Emfit movement sensor as an automated screening tool for sleep apnea in the ischemic stroke patients
(Turun yliopisto, 2022-05-13)
Stroke is a common cause of death and a major reason for disability. Stroke survivors can have very difficult symptoms and require very intensive and expensive rehabilitation. Sleep disordered breathing, sleep apnea, is ...
Determining the fatty acid compositions of human brown and white adipose tissues in vivo using clinical proton magnetic resonance spectroscopy
(Turun yliopisto, 2021-03-18)
Brown adipose tissue (BAT) of adult humans is metabolically active tissue which has been shown to have health-benefiting effects, such as preventing from type 2 diabetes and obesity. To develop BAT based treatment methods ...
YBCO superconductor on buffered metallic tapes for coated conductor based applications: Modifying the pinning landscape for improving the critical current densities
(Turun yliopisto, 2021-09-25)
High temperature YBa2Cu3Oz<sub>6+x</sub>superconducting films are deposited on top of differently fashioned buffered metals to enhance the critical current density and its isotropy for coated conductor applications. The ...
Statistical properties of solar energetic proton events
(Turun yliopisto, 2023-05-30)
The Sun is the source of several different kinds of high-energy particles that are most prominently released in sudden large eruptions, known as solar energetic particle events. These particles, which escape the Sun and ...
Determination of absorbed dose by radiophotoluminescence dosimetry and Monte Carlo simulations
(Turun yliopisto, 2023-04-21)
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 ...
Memristor devices based on low-bandwidth manganites
(Turun yliopisto, 2022-12-12)
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 ...
