11. Modeling and Simulations of Multiphysics Phenomena ad Performance in Proton Exchange Membrane Fuel Cells
Sammanfattning : Proton exchange membrane fuel cells (PEMFCs) are considered as the mostpromising alternative power sources with a wide variety of applications owing to their attractive advantages compared to other conventional power sources. During the past decades, the cell performance has been gradually improved. LÄS MER
12. Avoiding slopping in top-blown BOS vessels
Sammanfattning : Slag formation plays a decisive role in all steelmaking processes. In top-blowing Basic Oxygen Steelmaking (BOS), i.e. in the LD process, an emulsion consisting of liquid slag, dispersed metal droplets and solid particles will, together with process gases, form an expanding foam.

13. An Operational View on Foaming and Slopping Control in Top-blown BOS Vessels
Sammanfattning : Slag formation plays a decisive role in all steelmaking processes. In top-blowing Basic Oxygen Steelmaking (BOS) i.e., in the LD process, an emulsion consisting of liquid slag, dispersed metal droplets, undissolved particles and solid precipitates will, together with process gases, form an expanding foam.

14. Postural control and adaptation to threats to balance stability
Sammanfattning : Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory systems.

15. Oxidative stress, macrophages, iron, and atherosclerosis
Sammanfattning : Macrophages have a great capacity to take up exogenous material, such as oxidatively modified low density lipoproteins (oxLDL) and different sources of iron containing structures. OxLDL is taken up into macrophage lysosomes by receptor-mediated endocytosis, but poorly degraded, resulting in foam-cell formation. LÄS MER
