1. Low-energy ions around comet 67P/Churyumov-Gerasimenko
Sammanfattning : Low-energy ions play important roles in the formation of the plasma environment around a comet. Reliable ways of measuring these ions are therefore of high importance to fully understand the processes and dynamics of this environment. Unfortunately, low-energy ions are infamously difficult to detect. LÄS MER
2. The effect of spacecraft charging on low-energy ion measurements around comet 67P/Churyumov-Gerasimenko
Sammanfattning : A spacecraft in space interacts with the surrounding environment and aqcuires an electrostatic potential. Charged particles are constantly bombarding the surface of the spacecraft, and at the same time solar EUV radiation induces photoemission, causing electrons to be emitted from the surface. LÄS MER
3. A safe road transport system : factors influencing injury outcome for car occupants
Sammanfattning : Given that over a million people are fatally injured in road accidents each year, the need for a systematic proactive approach is undeniable. The Swedish Road Administration (SRA) has developed a model for a safe road transport system based on the Vision Zero philosophy, to identify and prevent deviations from a safe system approach with regard to crashes.

4. Chemical genetics and immunomodulation in Salmonella enterica serovar typhimurium infection
Sammanfattning : Salmonella sp. are versatile bacteria that survive and replicate in a plethora of environmental niches and hosts, including humans. The illnesses caused by various serovars in humans range from mild gastroenteritis to severe systemic disease such as typhoid fever that still cause an important number of casualties especially in developing countries.

5. Governance and Development of the East African Community : The Ethical Sustainability Framework
Sammanfattning : The pursuit of sustainability of governance and development has become a major challenge in contemporary times because of increasing realization that: various ecological and social systems are interconnected; and the complexity of our natural and constructed environs requires holistic approaches to avoid catastrophic fissures in the systems on which humans depend. As regional governments such as the East African Community (EAC) become important in Africa (and other regions), they present opportunities to generate cross-national approaches to achieving sustainability albeit success in that direction is limited and sporadic.
