Snelle en goedkope chips die extreem kleine hoeveelheden vloeistof (microfluïden) analyseren vormen de kern van gepersonaliseerde gezondheidszorg. Maar het ‘laboratorium op een chip’ is nog niet effectief genoeg. Dr. Paul Vulto en zijn onderzoeksteam ontwikkelden een techniek die het gebruik van microfluïdische…

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

Emeritus hoogleraar Ferdinand Feldbrugge bood op 29 november 2017 het door Brill-Nijhoff uitgegeven “A History of Russian Law” aan aan de decaan van de faculteit, Joanne van der Leun, het hoofd van de universiteitsbibliotheek Kurt De Belder en aan de Eerste Secretaris van de Russische ambassade, Yuri…

This thesis describes the development of improved formulations and alternative delivery strategies for polio vaccination.

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

Development of indicators to assess decoupling of economic development and environmental pressure in the EU-25 and AC-3 countries.

Heart failure is a major health care problem with high mortality.

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

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.

Humans perceive the real world through their sensory organs: vision, taste, hearing, smell, and touch. In terms of information, we consider these different modesalso referred to as different channels of information or modals.

EU Universe Awareness (EU-UNAWE), een educatief sterrenkundeproject van de Leidse Sterrewacht, heeft gloednieuw lesmateriaal ontwikkeld: Universe in a Box. Het toegankelijke lespakket is ontworpen om de moeilijke en soms abstracte concepten van sterrenkunde uit te leggen aan jonge kinderen van 4 tot…

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Het project Universe Awareness (UNAWE) van de Universiteit Leiden organiseert een Kickstarter crowdfunding campagne om de lespakketten van 'Universe in a Box', een lespakket voor sterrenkunde, zoveel mogelijk te kunnen verspreiden onder kansarme gemeenschappen over de hele wereld. De campagne werd gelanceerd…

What categories exist in the languages of pastoralists? Do these semantic concepts reflect universal or languagespecific tendencies? What (environment? culture?) governs the similarities (or the differences) attested crosslinguistically in cattle colour systems?

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

Description of 20th century changes in the Dutch flora: Description and interpretation (1999 - 2005)

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

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.

Acute cardiovascular clinical events such as myocardial infarction and cerebral stroke represent the major cause of death in Western societies. These pathologies are primarily resulting from atherosclerosis, a progressive condition characterized by the accumulation of lipids, immune cells, and fibrous…

The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

The ongoing increase in antimicrobial resistance combined with the low discovery of novel antibiotics is a serious threat to our health care.

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

Description of The Regional Network on the Synergy between the Convention on Biological Diversity and the UN Convention to Combat Desertification.

This study has been carried out in the community of Sukamiskin, a kelurahan (‘village’) in Bandung, the Capital of West Java Province, located in the Sunda Region of Indonesia.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…
