1. Visual Flow Display for Pilot Spatial Orientation
Abstract : Pilot spatial disorientation (SD) is a significant cause of incidents and fatal accidents in aviation. The pilot is susceptible to SD especially in low visibility when the visual system is deprived of information from outside the cockpit. READ MORE

2. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern
Abstract : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

3. Effects of gravity and posture on the human lung
Abstract : The presence of the gravitational force at the surface of Earth affects all of the organ systems in landliving creatures. The function of the lung is particularly susceptible to changes in the direction and magnitude of gravity because of the elastic structure of this organ. READ MORE

4. Lung function in micro- and in hypergravity
Abstract : The lung is extremely susceptible to gravity, even during short-term changes of the gravity vector, because it is a mixture of air and elastic tissue components. Yet, there is limited knowledge of the effects of gravity on the respiratory system. READ MORE

5. Body posture and gravity as determinants of lung perfusion and ventilation
Abstract : Normal lung gas exchange depends on an intimate match between regional ventilation and regional blood flow in the lungs. The beneficial effect of the prone posture in acute respiratory failure is well documented but the mechanisms involved are not completely understood. READ MORE
