In this dissertation, matching, entropy, holes and expansions come together. The first chapter is an introduction to ergodic theory and dynamical systems.

Heart failure is a major health care problem with high mortality.

By training with virtual opponents known as computer generated forces (CGFs), trainee fighter pilots can build the experience necessary for air combat operations, at a fraction of the cost of training with real aircraft.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

What are the flows of C&DW (e.g. bricks, concrete, gypsum and wood) in the case study countries ? How to define the specification for each material to be quantified? What indicators should be used to identify the pattern of each C&DW management system? How to interpret the MFA results in relation…

Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

Does a high quality prairie restoration in an urban/agricultural landscape provide invertebrates necessary for a sustainable ecosystem?

Woensdag 16 juni promoveert wiskundige Ionica Smeets op het onderwerp kettingbreuken. In het Academiegebouw zal ze tegenover een gezelschap van nationaal en internationaal gerespecteerde wiskundigen haar proefschrift verdedigen. ‘Ik ontdekte de kettingbreuken en dacht: leuker dan dit wordt het niet.…

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

Does the presence of Ring-necked parakeets negatively influence feeding and feeding behaviour of native bird species on artificial bird feeders and if so, what are possible solutions?

Leiden University would like to express its concern about the proposed Hungarian higher education draft law, which, if adopted, would make the functioning of Central European University (CEU) in Budapest nearly impossible. These changes would endanger the academic freedom vital for CEU’s continued operation…

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…

Wil je succesvol stoppen met roken? Dan is het vooral belangrijk of je jezelf kunt zien als niet-roker. Psycholoog Eline Meijer heeft ook ontdekt dat gestopte rokers die daarin niet slagen een grotere kans op terugval hebben. Dat komt vaker voor bij rokers met een lagere sociaaleconomische achtergrond.…
