In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

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.

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

This proposed research uses ego-documents from visual artists that were not intended for publication to reassess the scholarly debate on the demise of the Russian Avant-garde aesthetic in the twenties and early thirties of the 20th century.

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

Technologies that help to enhance our educational environments can be found everywhere.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

Op 7 december 2021 verdedigde Georgina Kuipers het proefschrift 'Beschadigd vertrouwen'. Het promotieonderzoek is begeleid door prof.mr. W. den Ouden en prof.dr. M.A. van der Steen (EUR).

Over the last decades, aviation safety has improved strongly. As a downside, airline pilots do not have as many opportunities to develop through experience the competencies that they need in critical situations.

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

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

In order to be able to develop effective medicine and treatments to prevent or cure autoimmune diseases or cancer we need to understand the mechanisms how they arise and what drives their course.Unravelling the fundamental molecular mechanisms influencing the onset and course of diseases such as allergies,…

In het academisch jaar 2023-2024 biedt het interdisciplinaire onderzoeksprogramma Sociale Veerkracht en Veiligheid vier vakken aan voor studenten die beginnen met het derde jaar van hun bachelor. Deze vakken zijn te volgen binnen de ruimte voor keuzevakken. Je kunt de vakken afzonderlijk als keuzevak…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

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…

De onderzoeksgroep Cyber Security Governance bestudeert de impact van moderne technologie op governance, soevereiniteit, wetshandhaving en internationale betrekkingen, en levert toonaangevend academisch onderzoek en beleidsinzichten.

In analogy to mathematical proofs, the goal of a proof system is for a prover to convince a verifier of the correctness of a claim.

Breeding for resistance becomes more and more important because we want to reduce the use of pesticides. A fast and cheap alternative can be to make use of morphological or chemical markers.
