Sammanfattning : Purposeful and well-coordinated movements depend on the control exerted by dopamine (DA) on the basal ganglia (BG) network. Accordingly, dysfunctions or lesions of the dopaminergic system in the BG can result in an overall poverty and slowness of movement, cardinal features of Parkinson´s disease (PD), or in dyskinesias, exaggerated and involuntary movements resulting from L-DOPA pharmacotherapy.

Sammanfattning : In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. LÄS MER
3. Collision Threshold Pressure : A novel measure of voice function Effects of vocal warm-up, vocal loading and resonance tube phonation in water
Sammanfattning : The phonation threshold pressure (PTP), i.e., the smallest amount of subglottal pressure needed to initiate and sustain vocal fold oscillation, is frequently difficult to measure due to the difficulty for some subjects to produce extremely soft phonation. In addition, PTP values are often quite scattered. LÄS MER
Sammanfattning : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. LÄS MER
5. The role of scattered trees in soil water dynamics of pastures and agricultural lands in the Central American Tropics
Sammanfattning : Trees affect the water cycle, and thus the amount of groundwater and surface water, through their effects upon the local microclimate and edaphic properties; in particular through rainfall interception, evapotranspiration, and infiltration. Empirical data about the effects of scattered trees upon hydrological processes have been largely lacking, especially for tropical regions. LÄS MER
