Investigation of [N-X-N]+ and [N-C-N]+ complexes in solution
(2017-11-02)Halogen bonding is a weak interaction. In this thesis the three center four electron halogen bond, [N−X−N]+, has been studied. The lighter halogens form highly unstable halonium ions that are reactive towards nucleophiles ... -
Signal Transduction in Photoreceptor Proteins
(2017-10-26)The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals ... -
Measuring the Evolution of Meta-models, Models and Design Requirements to Facilitate Architectural Updates in Large Software Systems
(2017-10-24)Background: In order to reduce complexity of the system and its development cost, the architecture of large software systems is often developed following the MDE (Model-Driven Engineering) approach. Developing architectures ... -
Peroxiredoxins in Redox Signaling and Aging
(2017-10-23)Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not ... -
Plant Oxylipins and Lipid Transfer Proteins in Defense
(2017-10-20)Oxylipins, the oxygenated metabolites of polyunsaturated fatty acids (PUFAs), are found in many eukaryotic organisms. In plants, several enzymes can produce different types of oxylipins, and the chloroplast structural ... -
Creating Optical Activity: Total Spontaneous Resolution and Viedma Ripening
(2017-10-18)The creation of optical activity has been considered as something impossible even though reports of such creation via total spontaneous resolution since the 1940´s have been published. More recently Viedma ripening have ... -
Proactive Software Complexity Assessment
(2017-10-16)Large software development companies primarily deliver value to their customers by continuously enhancing the functionality of their products. Continuously developing software for customers insures the enduring success of ... -
Contracts and Computation — Formal modelling and analysis for normative natural language
(2017-10-11)Whether we are aware of it or not, our digital lives are governed by contracts of various kinds, such as privacy policies, software licenses, service agreements, and regulations. At their essence, normative documents like ... -
Evaluation of suitable nursery areas for penaeid shrimps in shallow water systems in southern Mozambique
(2017-10-09)Tropical shallow water habitats such as estuaries, mangrove forests and seagrass beds are important nursery areas for juveniles of many commercially important species including penaeid shrimp. Penaeids are one of the most ... -
Understanding Software Design for Creating Better Design Environments
(Chalmers University of Technology and Göteborg University, 2017)Context: Software design is considered an essential activity to analyze software requirements in order to produce a description of the software's internal structure that will serve as the basis for its construction. Models ... -
The solution conformations of macrocycles. Applications in the exploration of weak interactions and in drug development
(2017-09-26)Understanding the solution conformation and dynamics of molecules with biological relevance, as well as the impact of their conformation stabilizing weak interactions, is for example important for drug design. Macrocycles ... -
Microbial communities in anammox and nitrifying biofilms
(2017-09-19)Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. ... -
Airborne particulate matter in a Sub-Saharan Africa city: Nairobi, Kenya, and at an Equatorial high altitude site: Mount Kenya
(2017-09-13)In Sub-Saharan Africa (SSA), air quality is gravely understudied despite the existing influential factors such a rapid urbanization and population growth that negatively affect the environment. Majority of urban areas in ... -
Mobile phones in school: From disturbing objects to infrastructure for learning
(2017-09-06)Amid digitalisation, the mobile phone has pervaded society and become one of the most widespread digital technologies. In school, the mobile phone has stirred up conflicts and tensions visible in public debate as well as ... -

Proteostasis and Aging in Saccharomyces cerevisiae - The role of a Peroxiredoxin
(2017-08-25)Aging is characterized by a progressive decline in physiological functions that limits biological processes, increases the risk of disease, and ultimately leads to death. At the cellular level, aging is associated with ... -
Child–Robot Interaction in Education
(2017-08-25)Advances in the field of robotics in recent years have enabled the deployment of robots in a multitude of settings, and it is predicted that this will continue to increase, leading to a profound impact on society in the ... -
Sexual signalling and noise pollution - implications for courtship behaviour and reproductive success in two vocal species of marine gobies
(2017-08-24)Many marine animals use acoustic signals to mediate social interactions. Acoustic cues and signals are especially important in water because sound is unique as a sensory modality propagating with little attenuation over ... -
Designer magnetoplasmonics for adaptive nano-optics
(2017-08-24)Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple ...
