Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…

In De verwoestingen van Rusland beschrijft politicoloog Hans Oversloot (Universiteit Leiden) de uiterst turbulente geschiedenis van de Sovjet-Unie en de Russische Federatie van de afgelopen 35 jaar. Aan de orde komen onder meer de teloorgang van het socialisme door Gorbatsjov, de opkomst van de oligarchen…

Stellar feedback is a crucial ingredient in the evolution of galaxies.

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

The Low Frequency Array enables studies of low-frequency carbon radio recombination lines with unprecedented sensitivity, spectral and spatial resolution.

In Oost-Azië staat de autoritaire as van Rusland, China en Noord-Korea recht tegenover de democratische as van Zuid-Korea, Japan en Taiwan. Deze laatste drie landen hebben elk een uniek en effectief antwoord gevonden op de macht van China in de regio en zijn erin geslaagd de druk van hun dictatoriale…

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

Het belangrijkste doel van dit onderzoek is om de steden van het Romeinse Nabije Oosten in de keizertijd in kaart te brengen, met een focus op locatie, stadsgrootte en stedelijke kenmerken, om de vorm van het stedelijke systeem en de niveaus van integratie te bestuderen.

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.

In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…

Understanding how chemical complexity emerges during star formation requires connecting molecular material preserved in interstellar ices with that observed in the gas phase after protostellar heating begins.
