1. Wafer Bonding for Spaceflight Applications : Processing and Characterisation
Abstract : Bonding techniques intended for assembling space microsystems are studied in this work. One of the largest problems in bonding pre-processed semiconductor wafers are the severe process restrictions imposed by material compatibility issues. READ MORE

2. Nitric oxide and the lung : effects of spaceflight and hypergravity
Abstract : Nitric oxide (NO) is an important signal molecule in the body, in particular in the cardiovascular system. This highly reactive molecule is difficult to detect in tissues, but in gas-filled cavities such as the airways it can be detected in part per billion amounts. READ MORE

3. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus
Abstract : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. READ MORE

4. Effects of unloading and resistance exercise on skeletal muscle function, size and composition in man
Abstract : Exposure to microgravity, i.e., spaceflight, causes muscle unloading leading to muscle atrophy and dysfunction. Thus, there is a need for effective countermeasures to combat these effects. READ MORE

5. Cardiovascular function after long-term bed rest
Abstract : On earth, daily activities involve standing, changes of posture and various types of muscle action, all of which challenge the cardiovascular regulation. Removal of the orthostatic stress for a longer period, as during spaceflight or head-down tilt bed rest, consistently results in cardiovascular deconditioning. READ MORE
