Photochromic sodalite, Na8(AlSiO4)6(Cl,S)2, has been a topic of research for almost 100 years, though only recently has a deep understanding of its remarkably fatigueresistant colour change been obtained. Aside from the ...

The subject of this thesis is centered on a mineral called hackmanite, also known as photochromic sodalite. It is found naturally in remote, mountainous places in Afghanistan, Pakistan, Greenland, Russia, Canada, and the ...

Amazonia is the largest remaining tropical rainforest. As such, it is globally important both in terms of carbon and water cycles as well as biodiversity. As in most areas of the tropics, deforestation is also alarmingly ...

Human activities can negatively impact biodiversity, including bats, leading to excessive mortality, population declines and potentially species extinction. Amongst these threats, wind power and light pollution are both ...

In this thesis we study questions on the distribution of primes and multiplicative orders modulo prime numbers. The problems are attacked using methods from analytic and algebraic number theory. In the first article, ...

Knowledge on flyway structures, year-round spatiotemporal distributions and migration strategies is a key for understanding the ecology of migratory populations and the evolution of migratory behaviours. Knowledge on these ...

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 ...

Spiders (Araneae) are the largest order of Arachnida and the sixth most speciose order of Animalia, comprising more than 50,000 extant species as well as over 1,400 species known from fossils. Despite this immense diversity ...

Infectious diseases in natural populations are important areas of research in ecology and evolution as they describe how parasites influence the host fitness. A host may undergo adaptive evolution against the parasite by ...

This thesis focused on the proanthocyanidins (PAs), a class of plant specialized metabolites that have a wide range of industrial applications. They play a vital role in the production of various food and feed products. ...
