Magnetic resonance study of atomic hydrogen stabilized in matrices of hydrogen isotopes below 1K
(Turun yliopistoAnnales Universitatis Turkuensis A I 555, 2017-03-03)
In this thesis, we report on an experimental study of H, D and T atoms stabilized in solid molecular matrices of hydrogen isotopes at temperatures down to 70 mK. Previous experiments have been carried out at ...
Observational studies of core-collapse supernova progenitors and their environments
(Turun yliopistoAnnales Universitatis Turkuensis A I 558, 2017-05-12)
In this doctoral thesis, core-collapse supernova progenitor stars are studied. Different ways to gain information on the progenitor stars of core-collapse supernovae are explored, with an emphasis on using the environments ...

Spectroscopic Studies of III-V Semiconductor Materials for Improved Devices
(Turun yliopistoAnnales Universitatis Turkuensis A I 505, 2015-01-17)
Defects in semiconductor crystals and at their interfaces usually impair the properties and the performance of devices. These defects include, for example, vacancies (i.e., missing crystal atoms), interstitials (i.e., extra ...
Surface Studies of Thiolate Adsorbates on Some Metals
(Turun yliopisto, 2008-12-05)
The results and discussions in this thesis are based on my studies about selfassembled thiol layers on gold, platinum, silver and copper surfaces. These kinds of layers are two-dimensional, one molecule thick and covalently ...

Implementability of observables, channels and instruments in quantum theory of measurements
(Turun yliopisto, 2017-11-25)
Measurements play an integral part in any scientific theory. Indeed, the observations revealing causal behaviour and symmetries in our world of experience lie at the heart of determining the truth or the falsity of scientific ...
The supermassive binary black hole system OJ287
(Turun yliopistoAnnales Universitatis Turkuensis AI 492, 2014-08-15)
Abstract
This doctoral thesis concerns the active galactic nucleus (AGN) most often
referred to with the catalogue number OJ287. The publications in the thesis
present new discoveries of the system in the context of ...
Research and development of III-V semiconductor surfaces for improved device interfaces
(Turun yliopistoAnnales Universitatis Turkuensis A I 473, 2013-10-19)
This thesis is devoted to understanding and improving technologically important
III-V compound semiconductor (e.g. GaAs, InAs, and InSb) surfaces and
interfaces for devices. The surfaces and interfaces of crystalline ...
Multifrequency VLBI Observations of Selected Active Galactic Nuclei
(Turun yliopistoAnnales Universitatis Turkuensis A I 425, 2011-10-15)
In this dissertation, active galactic nuclei (AGN) are discussed, as they are seen with the high-resolution radio-astronomical technique called Very Long Baseline Interferometry (VLBI). This observational technique provides ...
