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.

Co-ordination Action for Innovation in Life-Cycle Analysis for Sustainability: deepening, broadening and leaping forward the LCA methodology.

Nederland en China kunnen van elkaar leren slimmer om te gaan met afvalwater uit huishoudens en veeteelt. Leidse, Wageningse en Chinese wetenschappers gaan samen met betrokkenen werken aan haalbare oplossingen die milieu, gezondheid en economie vooruit helpen.

How to contribute to a quantum leap of eco-industrial symbiosis in China?

Eduard Fosch-Villaronga, universitair hoofddocent bij eLaw, heeft bijgedragen aan 'Cyber–Physical–Human Systems', een boek waarin de nieuwste ontwikkelingen in interacties tussen cyberfysische systemen en mensen worden onderzocht.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

In order to gain a better insight into the basis of the rapid jasmonic acid (JA)-mediated stress response, an integrated approach using a targeted high-resolution mass spectrometry-based (HRMS) platform, was conducted to monitor the metabolism of JA using the model system of cell suspension cultures…

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

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…

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Het onderzoek van eLaw sluit vooral (maar niet uitsluitend) aan bij het facultaire onderzoeksprogramma Effective Protection of Fundamental Rights in a Pluralist World. De centrale onderzoeksvraag van dit programma is: welke kansen en bedreigingen vloeien voort uit de institutionele en normatieve diversiteit…

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

INFORM (Introduction of the data protection reform to the judicial system) is een project dat door het Directoraat-Generaal Justitie and Consumentenzaken van de Europese Commissie wordt gefinancierd.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

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.

Which traits and/or trade-offs determine benefits of being deciduous or evergreen?

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

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.

This dissertation presents new cryptographic protocols, which can be divided into two families.

Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

Leiden University and the Ministry of Infrastructure and Water Management are involved in a collaboration in the form of a research project titled 'Data-Driven Risk Assessment in Infrastructure Networks'
