This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Several single-stranded RNA viruses make use of Xrn1-resistant RNAs in their 3’ untranslated regions of their genome RNAs in order to increase their pathogenicity.

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.

Globally and regionally, biodiversity is declining and there are shifts in species’ occurrences and functional traits.

Plastics have become an integral part of modern society due to their versatility and durability.

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

Op 11 november 2021 verdedigde Mariana Gkliati het proefschrift 'Systemic Accountability of the European Border and Coast Guard'. Het promotieonderzoek is begeleid door promotoren prof.dr. P. Rodrigues en prof.dr. L. Besselink (UvA).

This thesis investigates catalytic reactions at the atomic scale using scanning tunneling microscopy (STM), with a focus on Fischer–Tropsch synthesis, a key industrial process that converts hydrogen and carbon monoxide into liquid fuels.

This thesis investigates innovative and classical strategies in glycoconjugate vaccine development to address the growing threat of multidrug-resistant bacterial infections.

In this thesis the links between allergy and intestinal health, the gut microbiome (GM), and external factors were studied by exploring the metabolome in longitudinal clinical studies and in vitro models.

This thesis aims to develop model-based approaches to optimize drug dosing in patients with overweight and (morbid) obesity.

Anionic particles play an important role in biological systems where they fulfil many essential functions for cells.

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).

Wat zijn de vaak onzichtbare cognitieve gevolgen van multiple sclerose? Die bracht Maureen van Dam tijdens haar promotieonderzoek in kaart. ‘De lichamelijke symptomen zien mensen meestal wel, maar de cognitieve symptomen verdienen minstens net zoveel aandacht.'

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

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…

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

The research described in this thesis has, using the zebrafish as a model system, shed new light on the intricate relationship between TB and DM2, in particular on the role of leptin, SHP-1 and glucocorticoids.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Om de juiste klinische beslissingen te nemen of effectieve diagnostische testen en behandelingen te kunnen ontwikkelen, is het belangrijk om de onderliggende mechanismen van een aandoening of een bepaald gedrag te begrijpen.

Als een nieuwe methode is ontwikkeld om een (neuro-)psychologische aandoening of hieraan gerelateerde gedragsfactoren te herkennen en te behandelen, kan deze nog niet direct in de klinische praktijk worden ingezet. Eerst moet de methode geëvalueerd worden, bij voorkeur in gerandomiseerde, gecontroleerde…

Understanding how nature captures and transfers solar energy is essential both for elucidating biological photosynthesis and for guiding the design of artificial light-harvesting systems.

In this thesis, Quantum computing, norms, and polynomials, we investigate the interplay between quantum mechanics, complexity theory, and functional analysis, three central areas of physics, computer science, and mathematics, respectively.

During the development of the (human) body from a single fertilized egg, organs and structures must form. The development and growth of biological forms is called morphogenesis.

Adenosine diphosphate ribosylation (ADP-ribosylation) is a fascinating post-translational modification (PTM) that plays a role in a variety of cellular processes and is associated with several diseases, including cancer and viral infections.

Het vertrekpunt van dit onderzoek is de bevinding dat het menselijk brein vatbaar is voor allerlei denkfouten en vooringenomenheden (biases), die onze percepties kleuren en onze redenaties beïnvloeden, zonder dat we dit bewust doorhebben. Integendeel, mensen hebben veelal het gevoel dat zij slechts…
