The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.

Klinische psychologie richt zich vooral op de toepassing van wetenschappelijke psychologische kennis op assessment, preventie en behandeling van psychopathologie.

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

The last decades it is increasingly recognized that acute as well as chronic postoperative pain is an important problem. Treatment and prevention of postoperative pain is a challenge, especially in special patient populations where there is only limited guidance on how to optimally use opioids.

Cardiovascular disease is the number one cause of death worldwide. The most important risk factor for developing this disease is high cholesterol levels in the blood.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law.

Over the last decades, aviation safety has improved strongly. As a downside, airline pilots do not have as many opportunities to develop through experience the competencies that they need in critical situations.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The present thesis focuses on the pharmacological concept of drug-target interaction, which dates back to the beginning of modern pharmacology.

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

The coursework within the Science Communication and Society (SCS) specialisation prepares students for internships and a career in communication about science and health.

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.
