During space sojourns, astronauts experience musculoskeletal deconditioning caused by the lack of gravity. The adaptation of the musculoskeletal system to inactivity and unloading of the weight-bearing limbs may be countered by daily exercise. However, current exercise devices and strategies employed on the International Space Station (ISS) do not appear to …
Magnetic resonance imaging (MRI) is a diagnostic method that is used for broad range of hospitalized patient, emergency patients, chemotherapy treated and as well the patients that may have infectious diseases. Because the examinations of different patients are usually performed with the same equipment in the same environment, the surfaces …
Omnipresence of sensor-equipped devices spurred rapid development of e-health and mhealth applications in the past decades. Despite their wide-spread adoption in the form of wearables, such devices are ultimately not a universal or ideal solution for regular health monitoring due to their reliance on battery, requiring skin contact and general …
Plastic pollution is a global issue, yet our understanding of its impact on organisms and ecosystems remains limited. My PhD thesis explores the presence of microplastics (MP) in river ecosystems, their interaction with freshwater hyporheic biofilms and specifically, the response of hyporheic biofilms to polyethylene terephthalate (PET) pollution in the …
A paradigm shift is occurring in the assessment of exposure to urban environmental stressors. Improved accuracy of personal monitors has enabled researchers to study exposure at the individual level. Monitoring stations are the primary reference point for air quality in urban environments, although there is a need to assess exposure …
Plasma facing components (PFC) in fusion devices are exposed to plasma. Plasma-wall interaction processes are important as they impose a series of constraints on the components. The lifetime of the PFCs is dominantly determined by two processes: erosion and fuel retention. At the first wall the erosion is caused by …
Electrochemical energy conversion devices such as fuel cells (FCs) and water electrolyzers (WE) have attracted attention from the scientific community for their unique ability to store electrical energy in the form of hydrogen and then generate electricity by the reverse process. Unfortunately, those devices rely on a significant amount of …
Atmospheric pressure non-equilibrium plasma jets in material processing have received substantial attention in the past two decades and are still in the developing stage with a growing interest in material synthesis and surface processing. The main opportunities of these techniques are their potential cost reductions in apparatus and handling. Because …
The use of low-cost sensing technologies increasingly used in participatory environmental health studies brings both opportunities and challenges. While previous research mostly focused on technical aspects, this thesis brings participants to the foreground and articulates their experiences. It aims to evaluate if low-cost sensing technologies are fitfor- purpose in environmental …
With the increasing use of electricity powered devices and processes in our daily lives, the need for the precise measurement of electrical currents across more than 15 decades from below nA to tens or hundreds of kA has become inevitable both for billing and more optimal energy distribution purposes as …
