De Kinderrechtenmonitor laat zien hoe het gaat met kinderen die in Nederland opgroeien. Met deze monitor wordt gemeten of en hoe kinderrechten, zoals vastgelegd in het Internationaal Verdrag inzake de Rechten van het Kind (IVRK), in Nederland worden nageleefd.

Het Sport Data Center (SDC) bestaat uit de data science disciplines van de Universiteit Leiden en de TU Delft, in combinatie met sportwetenschappelijke takken van het Amsterdam Institute of Sport Science en het Sports Engineering Instituut van de TU Delft.

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

There is accumulating evidence for an increase in severe global drought events. In particular, Europe experienced several severe droughts in 2003, 2015, and 2018 (unprecedented in the past 2,110 years). Such droughts have caused serious and far-reaching impacts on terrestrial ecosystems.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

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

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Willem Bilderdijk (1756-1831) was de grootste dichter van zijn tijd, maar ook een dwarsdenker in eeuwig verzet tegen de tijdgeest, en een zonderlinge hypochonder, die tientallen jaren leefde met

This dissertation is about Bayesian learning from data. How can humans and computers learn from data?

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

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

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

This thesis examines enzyme domain architecture and engineering to improve the breakdown of lignocellulose and starch, abundant biopolymers crucial for sustainable biofuel and biochemical production. Carbohydrate-active enzymes (CAZymes) facilitate this degradation, but the structural complexity of…

De afdeling Ondernemingsrecht en Financieel recht doet onderzoek op het terrein van onder meer het rechtspersonen- en vennootschapsrecht, het financieel verbintenissen- en aansprakelijkheidsrecht, corporate governance, duurzaamheid, het Nederlands en Europees financieel toezichtrecht, fusies en overnames,…

Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

This thesis applies data mining in commercial settings in the telecommunications industry.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Vandaag de dag liggen statistische methodes aan de grondslag van beslissingen in allerlei facetten van het leven, van de gezondheidszorg en agricultuur tot de financiële sector en marketing.

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

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

Let A be a commutative algebraic group over a field K, and let G be a finitely generated subgroup of the K-rational points of A. The purpose of this thesis is to study the degrees of the Kummer extensions relative to A,K and G.

This thesis describes the genetic and prokaryotic diversity of giant barrel sponges.

De masterclass is inleidend, en toegankelijk voor iedereen met interesse in wat het betekent om goed evaluatieonderzoek te doen. Kennis van methoden en technieken is niet vereist.

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?
