Skandapurāṇa IV presents a critical edition of Adhyāyas 70-95 from the Skandapurāṇa , with an introduction and annotated English synopsis.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

Mechanical interactions between cells and their environment play an important role in many biological processes.

Citizens in multiple crime-ridden countries strongly support the militarization of security—that is, placing the military in charge of traditional policing duties. Yet, we know little about the determinants of such support. Do people approve of militarization even in the face of human fatalities? Political…

In this thesis, classes of strongly interacting quantum field theories, have been studied.

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

Nietzsche’s concept of the agon or Wettkampf, a measured and productive form of conflict inspired by ancient Greek culture, has attracted a good deal of interest in Nietzsche studies and beyond. This book, by a leading expert on the topic, brings together research conducted over 20 years with a focus…

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Citizens’s attitudes towards trade are not only about the (perceived) economic effect. Commerce also has a variety of security implications. Employing an original experiment, political scientists Matthew DiGiuseppe (Leiden University) and Katja Kleinberg (Binghamton University) demonstrate that security…

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

Niels van Willigen (Institute of Political Science, Leiden University) puts Dutch participation in UN peacekeeping into an historical context. He analyses the reasons for the Dutch withdrawal from the 1990s onwards, and explores the obstacles and opportunities for a structural return. Van Willigen argues…

Do you have a creative and curious attitude towards scientific research? Do the creation of media and use of technology drive your research interests? Could you be a researcher who challenges scientific practice and pushes its boundaries? Then the Media Technology MSc programme at Leiden University…

Statistical distributions in LCA and converting between different representations of these distributions.

The aim of this thesis was to develop and evaluate a Ecological Professional Development Model to support preservice biology teachers to direct their own subject-specific ecological professional development route.

Negative perceptions of ambiguous social cues, social performance and physical arousal in socially anxious youth

We analyse the link between media consumption and the attitudes toward people living with HIV/AIDS in Chile. We used data from a sample of 1000 people, obtained in the 2011 wave of the World Values Survey (WVS). We use a logistic binary regression model by maximum likelihood. Our results suggest that…

Kyra van der Moezel defended her thesis on 7 September 2016.

The aim of this thesis was to develop aluminium salt-based nanoparticles that may ultimately be used as adjuvant in human vaccines.

The research described in this Thesis was aimed at designing and synthesizing nature-inspired compounds as part of TB vaccine discovery.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

A synchronic description of the endangered Slovene dialect spoken in the Gailtal valley in Carinthia, Austria.

Cyclic peptides are investigated as a platform to induce different orientations between various ligands.

The subjects of the texts vary from Demosthenes to the delivery of camels in early Islamic Egypt, and their provenances stretch from the Eastern to the Western Desert, and from the Egyptian Nile valley to Qasr Ibrim in northern Nubia.

Political scientist Nicolas Blarel (Leiden University) analsyses how non-state actors can (directly or directly) attempt to provoke conditions for a crisis between state actors that have nuclear capabilities. He argues that there is an urgent but complicated and understudied task to understand and manage…

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

In my thesis I study Majorana fermions from three different perspectives. The first one corresponds to non-interacting Majorana fermions that, however, pose non-trivial topological properties. The second one corresponds to strongly interacting Majoranas and the third to relic neutrinos. No one knows…

Jelke Bethlehem (Leiden University, Institute of Political Science) gives an overview of many aspects of polls: questionnaire design, sample selection, estimation, margins of error, nonresponse and weighting. As such, it is useful both for readers who want to gain a better understanding of the ins and…

The work described in this thesis focuses on the development of linear or cyclized peptide probes against protein N-methyltransferases to characterize their specific binding behavior, providing further binding details for inhibitory activity study.

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.
