1. Annoyance, quality- and safety aspects of sound in truck cabins
Abstract : For heavy vehicles the interior sound environment is still more or less just apassive result of the engineering of the different parts that make up the vehicle,although measures are taken to keep sound pressure level within legislatedboundaries. Additionally, the sound inside truck cabins is dominated by itslow frequency (LF) content, and is hence prone to impair task performance andreduce wakefulness as well as cause general annoyance and different adversehealth effects.

2. Perception of Sound and Vibration in Heavy Trucks
Abstract : Interior truck cabin sound has for some time been a concern for manufacturers. Today reasonably low sound pressure levels have been achieved using passive absorption. However low frequency sound is difficult to passively absorb and will hence dominate the interior sound. READ MORE

4. Characterisation of inputs and outputs of striatal medium spiny neurons in health and disease
Abstract : Striatal medium spiny neurons (MSNs) play a crucial role in various motor and cognitive functions. They are separated into those belonging to the direct pathway (dMSNs) and the indirect pathway (iMSNs) of the basal ganglia, depending on whether they express D1 or D2 type dopamine receptors, respectively.

5. Hydrology and Bed Topography of the Greenland Ice Sheet : Last known surroundings
Abstract : The increased temperatures in the Arctic accelerate the loss of land based ice stored in glaciers. The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere and holds ~10% of all the freshwater on Earth, equivalent to ~7 metres of global sea level rise. READ MORE
