My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Green infrastrucuture (GI) like urban farm and green roofs could provide many beneficial functions in cities. These include for example food production, flood prevention or increasing biodiversity. MultiGreen project aims at developing an integrated modelling tool to support…

The skin protects the body from unwanted influences from the environment as well as excessive water loss. The barrier function of the skin is located in the stratum corneum (SC).

If X is a locally compact Hausdorff space, then a representation of the complex C* algebra C_0(X) on a Hilbert space $H$ is given by a spectral measure that takes its values in the orthogonal projections on $H$.

Integrins play an essential role in multicellular life by connecting cells to the extracellular matrix.

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

Sorghum (Sorghum bicolor) is a major cereal crop that millions of subsistence farmers in Sub-Saharan Africa (SSA) rely on. However, the scourging impact of the root parasitic weed Striga (Striga hermonthica, a.k.a. “witch-weed”) has remained a major constraint hampering the productivity of sorghum in…

This study explores regional variation in the use of utterance-final particles by analyzing spoken Taiwan Mandarin data recorded from spontaneous conversations.

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

De overheid moet in een democratie openbaarheid nastreven, maar soms is geheimhouding noodzakelijk om belangen als veiligheid of privacy te beschermen. De Wet open overheid (WOO) bevat daarom een recht op overheidsinformatie, maar staat ook uitzonderingen daarop toe om in de wet gespecificeerde belangen…

The Directorate-General Police, Sanctions, and Protection has initiated this research project in order to gain insight in the nature and, if possible, the extent of the developments with regards to the pluralization of policing functions in the Netherlands in support of future policies for the benefit…

During the course of drug discovery translational steps are made.

An international partnership of brain researchers from 35 research centres - from the US to China - including the Leiden Institute for Brain and Cognition (LIBC), has collected resting-state functional MRI data from more than 1400 healthy volunteers and put the information online so that it is available…

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

OBJECTIVES: To determine whether the lipid/protein ratio and the total dry SC mass per surface area are related with the skin barrier function of controls and AE patients.

The barrier function of the skin is primarily provided by the stratum corneum (SC), the outermost layer of the skin. Skin barrier impairment is thought to be a primary factor in the pathogenesis of atopic eczema (AE).

An important feature of atopic eczema (AE) is a decreased skin barrier function. The stratum corneum (SC) lipids - comprised of ceramides (CERs), free fatty acids (FFAs) and cholesterol - fulfill a predominant role in the skin barrier function.

In her book Between Smiles and Grimaces, Mariska Kret shows us what differences there are between humans and animals, and more importantly, what similarities.

In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.

Our research regularly receives attention in the (Dutch) popular media. Here is an overview.

Recently the book “Privaatrecht 2050. De weg naar ecologische duurzaamheid” is published.

On Thursday and Friday, 1 and 2 March 2018, ICCL students and staff enjoyed a study trip to Brussels, including visits to the Permanent Mission of the Kingdom of the Netherlands, the European Commission and top law firm De Brauw Blackstone Westbroek.

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

Assuming everywhere good reduction we generalize the class number formula of Taelman to Drinfeld modules over arbitrary coefficient rings.

We prove a p-adic version of the work by Gross and Zagier on the differences between singular moduli by proving a set of conjectures by Giampietro and Darmon, who investigated the factorisation of a rational invariant associated to a pair of CM-points on a genus zero Shimura curve, obtained as the ratio…
