Making the Virtuagym e-platform suitable for wheelchair users with a spinal cord injury or lower limb amputation.

Around the sixth and seventh centuries, South and Southeast Asia saw a great religious change: Saivism largely took over from Vaisnavism. We’re going to look at the way in which Saivism, the religion of the god Siva, presented itself with respect to Vaisnavism. In particular we’ll investigate the role…

What is a good data protection law? How does a good data protection law evolve? Is European data protection law a good one? And whether the European data protection applicable to China?

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

The insights leading to the present project firstly manifested themselves in 2008, when I worked with field recordings on the basis of relatively well-established notions in music composition studies, such as ‘musical material’ and écriture. With hindsight, I understand the outcomes of those first experiments…

This historical study argues that the Mandaean religion originated under Sasanid rule in the fifth century, not earlier as has been widely accepted. It analyzes primary sources in Syriac, Mandaic, and Arabic to clarify the early history of Mandaeism.

In Luganda, the widest spoken minority language in East African country Uganda, the word for photographs is Ebifananyi. However, ebifananyi does not, contrary to the etymology of the word photographs, relate to light writings. Ebifananyi instead means things that look like something else. Ebifananyi…

The civilizations of ancient China and Mesoamerica, although not historically related and obviously different in many specific aspects (such as language and writing), show many interesting commonalities and similar tendencies in their cultural manifestations.

Both Europe and Latin America face challenges globally and at home. Conflicts over land and resources have been resurgent in recent years.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

The investigations described in this thesis lay out strategies aimed at advancing antibiotic research and development. The examples presented revolve around two main approaches: understanding drug-target interactions and target identification.

Ruobin Han defended her thesis on 21 March 2017

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

This dissertation derives from the development of tools for algorithmic composition which extract pitch materials from sound signals, analyzing them according to their timbral and harmonic properties, putting them into motion through diverse rhythmic and textural procedures.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

In our research protein translocation from Agrobacterium into yeast and plant cells is studied to obtain fundamental insights in the translocation process

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…
