Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

The Minor in Business Administration teaches business knowledge and skills that are important for your future career.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

In this study the flows of PVC and its additives through the Swedish Society were followed from the cradle to the grave (from production to waste treatment).

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

CMLCA is a software tool that supports the technical steps of the Life Cycle Assessment. The focus of the program is on advanced computational aspects of life cycle inventory calculations.

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

What is the population size/structure and distribution of tiger and leopard inside the Bardia National Park (BNP) compared with the population outside? What is the movement and home range and conflict pattern in time and space of tigers and leopards inside the BNP compared with outside? What constitutes…

By documenting lexical and morpho-syntactic patterns among P’urhepecha speakers in Mexico and the US diaspora, this project will investigate the sources of language variation. The ensuing online dialect atlas will serve as an online resource for speakers, learners and researchers of the language.

Sinds 2021 is de master ook in deeltijd te volgen, een parttime opleiding van 2-3 dagen per week, waarvan één vaste, verplichte dag op vrijdag.

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

LIACS is a partner in RISE_SMA, an interdisciplinary, international network combining excellent scholars and practitioners to enable vigorous knowledge sharing and to develop solutions for contemporary challenges for Social Media Analytics (SMA).

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

PNEC-pro is a user-friendly screening tool for professionals dealing with the assessment of surface water quality. The tool calculates local, watertype specific no-effect concentrations (PNEC) of copper, lead, nickel and zinc based on biotic ligand models (BLMs).

The idea of citizens and public professionals collaborating to provide public services has widely spread in several countries around the globe. Co-production is often presented as the go-to solution for challenges like a legitimacy crisis of both the government and the market, and financial concerns.…

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

Planets are formed in disks of gas and dust around young stars.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Carbohydrates are present on the surface of bacteria making them suitable antigen candidates for vaccine development. This thesis deals with the synthesis of two carbohydrate-based components; the capsular polisaccharide of S. aureus type 5 and teichoic acids from staphilococci and enterococci speci…

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.
