The organ in the Great Auditorium in the Academy Building has been played at walk-in concerts and University celebrations since 1998.

How do Humanitarian Response Organizations (HROs) and Virtual & Technical Communities (V&TCs) collaboratively govern disaster sensemaking processes, and what challenges shape the effectiveness of these collaborations between 2010 and 2016?

This volume challenges the idea that the development of ‘democracy’ is a story of rise and progress at all. It is rather a story of continuous but never completely satisfying attempts of interpreting the rule of the people.

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…

How do leadership behaviour repertoires take shape in public organizations?

Treatment with special stem cells seems to be a good option for suppressing the immune system in organ transplants. Researchers are trying to learn from processes that take place in the human body during pregnancy.

The research in the Biosyn group is focused on the design, synthesis and function of the four major types of biomolecules: nucleic acids, carbohydrates, peptides and lipids and hybrid structures thereof. These biomolecules and their derivatives are used in drug discovery and chemical biology, to develop…

Charisma K. Lepcha (PI, Sikkim University), Pradyut Guha (co-PI, Sikkim University), Rajib Sutradhar (co-PI, Christ University Bangalore) and Erik de Maaker (Leiden University) have been awarded a two-year grant of USD 18.000 to conduct research on the impact of ‘green farming’ on the sensitive mountain…

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

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.

The central theme of the NWO-project ‘The Promise of Organization’ is the evolution of political organization during the 19th century. We focus on the enthusiasm, arguments and concrete activities of the organizers as well as the criticism offered by opponents of modern political organization.

Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

My research focusses on site-specific compositional and performance practices of music for organ and electronics and their musical-spatial values.

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…

This study discusses the position of the monasteries in pre-1950s Tibetan societies and how that position was informed by Buddhist monastic ideology.

Growing public backlash against international organizations (IOs) and attacks of national political elites on the rule of law increasingly challenge governance by IOs.

The confinement of molecular catalysts in metal-organic frameworks has the potential to lead to significant improvements in selectivity, long term activity and catalyst stability.

Regenerative medicine is a new way of treatment that helps impaired cells, tissues, and organs work well again. We do this by repairing, replacing, or restoring cells, tissues, and organs after damage from illness or injury. This includes treating long-term diseases such as diabetes, kidney diseases,…

Petra van der Bekerom, Joris van der Voet, and Johan Christensen, three assistant professors at Leiden University, conducted a large-scale survey experiment about whether citizens are more negative about failing service delivery than private organizations.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

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.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

The Future of Multilateralism addresses current challenges and future perspectives of international and regional organizations. It aims to uncover how stable the foundations of global cooperation really are, particularly in the light of the latest unilateral and protectionist practices of international…

The lipid matrix in the stratum corneum (SC), the upper layer of the skin, plays a critical role in the skin barrier. The matrix consists of ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs).

Netherton Syndrome (NTS) is a rare genetic skin disease caused by mutations in the serine protease inhibitor Kazal-type 5 gene, which encodes the lympho-epithelial Kazal-type-related inhibitor. NTS patients have a profound impaired skin barrier function. Because SC lipids play a crucial role in the…

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.
