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.

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

Retorica is overal. In de Tweede Kamer, in de rechtbank, en in de collegezaal; maar ook op de markt, op Twitter, en op Facebook. Mensen proberen elkaar steeds weer te overtuigen met argumenten, te verleiden met emoties, en te imponeren met een gunstige zelfpresentatie. De minor Retorica bestudeert de…

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

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…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

Leiden is een echte studentenstad met een sfeervol en compact centrum waar je alles vindt wat je in je studentenleven nodig hebt. Den Haag is een internationale studentenstad en biedt jou een mooie mix voor een rijk en gevarieerd studentenleven.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

Studievoorlichting

Leiden is een echte studentenstad en heeft alles in huis om van jouw studententijd een onvergetelijke tijd te maken. En als internationaal georiënteerde studentenstad biedt Den Haag jou een mooie mix voor een geweldige studententijd.

Technology can drive peace and justice. Innovative solutions increasingly make use of new types of data, mobile technologies and social media. Big or small (data), high-tech or low-tech: the challenge is to maximise the benefits while minimising the risks that come with the so-called data revolution…

Participants in this course will learn to support student teachers and new colleagues in their professional development as teachers, with particular emphasis on the context of bilingual or international education, as in the ICLON World Teachers Programme (WTP).

Het primaire doel van de leerstoel is het uitvoeren en bevorderen van wetenschappelijk onderzoek naar de rol van het militaire instrument in hedendaagse conflicten en het verhogen van de kennis daarover in de Nederlandse maatschappij.

Een gesprek voeren of college geven over een oorlogssituatie is niet eenvoudig. Toch – of juist – is ook in de collegezaal deze behoefte mogelijk wel aanwezig onder studenten of docenten. We delen daarom hier tips en bronnen om het gesprek of college in goede banen te leiden.

The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

In this special edition of Information Polity there is a focus on the transparency challenges of using algorithms in government in decision-making procedures at the macro-, meso-, and micro-levels.

In this project of the Center for Public Values & Ethics (CPVE) ongoing research is conducted on the history of advice to Dutch central government by so-called State committees from 1814 to 2014. State committees have been installed by Dutch central government since 1814 to provide expert advice, research…

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

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

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…
