Gedurende een seminar van een uur zullen twee of drie sprekers…

Afgelopen weekend heeft Italië aan Nederland verzocht twee schepen terug te roepen die onder de Nederlandse vlag varen voor de Libische kust.

ILS organizes a new lunch seminar series where all researchers from Leiden Law School can present their research. The idea is to hear in a simple and nice way what researchers from other research programs and institutes are working on. During a seminar two or three speakers will present their research.…

Taalkundige Johan Rooryck gaat onderzoek doen naar leervermogen en kernkennissystemen, en hoe bezit in verschillende talen wordt uitgedrukt. Samen met collega-onderzoekers heeft hij twee NWO-subsidies van in totaal 2,75 miljoen euro ontvangen voor de onderzoeksprogramma’s ‘Knowledge and Culture’ en…

Description of Development of a low cost technology for in-situ treatment of groundwater for potable and irrigation purposes (TiPOT) (2004 - 2007)

CREEA is a FP7 project on compiling and refining environmental and economic accounts. The project runs from April 2011 to March 2014.

Prof.dr. E.W. Meijer, lid van de Raad van Toezicht van de Universiteit Leiden, is op 28 februari benoemd tot Commandeur in de Orde van de Nederlandse Leeuw.

How does the management of Elephant Marsh Fishery in Malawi relate to wider contexts of policies, theories and regions? And how can the current management system be adapted to achieve long-term sustainability of the fishery?

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

Developing methodes to understand the evolution of patches in natural ecosystems

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

Producing green energy has become the main goal in our society in the search of reducing or eliminating the carbon emission from fossil fuels.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects of the shared venom system. Morphological changes included the partitioning of the mixed ancestral glands into two discrete glands devoted for production of venom ormucous…

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

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.

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

Cardiovascular disease is a major global burden and atherosclerosis is the main underlying pathological process.

In summary, the collective results described in this thesis show that nanoparticulate vaccines can be delivered intradermally by coated and hollow microneedles and evoke antigen-specific immune responses.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.
