Eerder schreef van Dijkhuizen boeken over duistere onderwerpen als pijn, demonische bezetenheid en exorcisme. Maar voor zijn nieuwste boek koos hij een schijnbaar luchtiger onderwerp: verzoening. Maar wat blijkt, verzoening is vaak juist helemaal geen ''happy affair''. Hij vertelde erover in een podcast…

In Afrika wonen 1,5 miljard mensen. Over 30 jaar zijn dat er 2,5 miljard. De impact van het continent op de wereldeconomie, maar bijvoorbeeld ook op het milieu, zal daardoor enorm toenemen. Onderzoekers van het Afrika-Studiecentrum Leiden (ASCL) zijn zich er al decennia van bewust dat Afrika een cruciale…

Do sustainability values play a role in motivating people to act for biodiversity in successful projects and in successful leadership action? And how could these values be incorporated in current economic valuation methods?

Afrika heeft een bevolking van 1,5 miljard mensen. In 2050 zal dit aantal naar verwachting stijgen tot 2,5 miljard. De impact van het continent op de wereldeconomie en samenlevingen, maar ook op het milieu, zal daardoor enorm toenemen.

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…

Op de Oude Sterrewacht bieden we een aantal manieren voor scholen om op bezoek te komen. Naast de rondleidingen die wij organiseren zijn er speciaal voor scholen ook workshops te doen.

How do nanoparticles bioaccumulate and biodistribute in organisms?

Do selenium nanoparticles in fish food cause subtle alterations in behavior of fish: effect of particles size and concentration?

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

This thesis describes the design, characterization and application of dextran based crosslinked network.

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

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’.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Identification of the products or product groups that have the greatest environmental impact from a life-cycle perspective using environmentally extended input-output analysis.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

Hoe en in welke mate kunnen groepen clinici en biomedici kennis uit klinische vakken en kennis uit de basisvakken expliciet maken en aan elkaar relateren?

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies.
