The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

Sustainable energy from wind and solar is most readily available near the sea.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

In this thesis we push the boundaries of high-resolution imaging at radio frequencies between 100 and 200 MHz. Using the International LOFAR Telescope that spans across Europe we achieve sub-arcsecond angular resolution.

Bij Cambridge University Press (CUP) verscheen onlangs van Ingrid Leijten het boek Core Socio-Economic Rights and the European Court of Human Rights. Het boek maakt onderdeel uit van de serie Cambridge Studies in European Law and Policy en heeft als onderwerp de bescherming van sociaaleconomische rechten…

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

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

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

The endocannabinoid receptors CB1R and CB2R are involved in a plethora of processes, and consequently are involved in many pathological conditions. Their wide distribution makes the CBRs both an interesting therapeutic target and hard to study.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

A convolutional neural network (CNN) is a biologically inspired algorithm, highly capable at processing images and videos.

Chapter 1,contains the numerical verification of the Birch and Swinnerton-Dyer conjecture for hundreds of Jacobians of hyperelliptic curves of genus 2, 3, 4 and 5.

Per 1 mei is Casper de Jonge benoemd tot hoogleraar Griekse Taal- en Letterkunde. ‘De Griekse literatuur komt niet alleen uit Athene: ook auteurs uit Egypte, Syrië en Klein-Azië schreven in het Grieks.’

Een samenwerking tussen het Instituut voor Strafrecht & Criminologie van de Universiteit Leiden en de hoogleraren strafrecht Marc Thommen en Sarah Summers van de Universität Zürich heeft voor een tweede maal geleid tot een interessant en leerzaam seminar voor Zwitserse en Leidse studenten.

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…
