Ze presenteerden de resultaten voor een volle collegezaal en in de aanwezigheid van de client voor wie zij aan de slag waren gegaan met een complex security…

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.

Komend academisch jaar 2017-2018 start een nieuwe bacheloropleiding bij de Universiteit Leiden. De studie “Security Studies” zal gegeven worden op de Haagse Faculteit Governance and Global Affairs. Sleutelstad sprak met opleidingsdirecteur Ruth Prins over de nieuwe studie, waar zij zelf ook een vak…

Jan van den Berg heeft zij proefschrift op 8 november 2018 verdedigd.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

In this thesis, we present new laboratory data of interstellar dust analogues.

Dit artikel gaat in op de onderzoekskloof door te onderzoeken hoe deze instanties hun personeel zo kunnen inzetten dat ze maximale prestaties leveren met het personeel dat ze hebben.

The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

Promotor: Jelle S. Kaastra Co-promotor: Jelle de Plaa

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

De auteurs presenteren een benadering voor het achterhalen van de voorkeuren van de bevolking voor gebruik in de optionele wegingstap in de Levenscyclusanalyse (LCA).

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

The increasing resistance of pathogenic bacteria to antibiotics necessitates the discovery of new medicines.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

Op 2 juli promoveert Jiaqi Wang. Het Leiden University Centre for Linguistics feliciteert Jiaqi!

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

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

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.
