The research programme Industrial Ecology aims to support the ecological transformation of society and environment towards sustainability. The research subject is Industrial Ecology in its broadest definition, covering environmental systems analysis, and incorporating the social and economic aspects…

Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Automated Machine Learning (AutoML) is widely used to automatically build a suitable practical Machine Learning (ML) model for an arbitrary real-world problem, reducing the effort of practitioners in the ML development cycle for real-world applications. Optimization is a key part of a typical AutoML…

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

On 13 October 2021 Ross Spence defended the thesis 'Collateral Transactions and Shadow Banking'. The doctoral research was supervised by Prof. M. Haentjens and Prof. A.M. Pacces (UvA).

Changing burial rites in Early Medieval Northern Gaul, 450-600 CE

The SNP genotyping line offers flexible genotyping for small and large projects at affordable price and high quality. The use as SNPs as molecular markers is very versatile and can be used for a wide variety of scientific questions ranging from paternity analysis, conservatuion genetis towards QTL…

Indonesia is experiencing various environmental challenges related to its fast economic growth. Therefore, it is necessary to have measurable and applicable indicators to obtain accurate data and information regarding the costs of adverse environmental impacts arising from economic activities to support…

What are the manifestations, antecedents and consequences of the cognitive uncertainty experiences of social care professionals?

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

Martin Richardson, who graduated in 1997 from what was then the Leiden LLM Programme in European Community Law (now: Leiden Adv LLM European and International Business Law, EIBL), has recently been appointed as a Senator of the College of Justice in Scotland, meaning that he is now a judge of the highest…

When do fire making tools appear in prehistory, and how might the use of these tools manifest in the archaeological record?

The principle aim of the project is to study the genesis and the quantitative properties of the Early Roman urban network of the Balkan and the Danube provinces.

Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

What is the population size/structure and distribution of tiger and leopard inside the Bardia National Park (BNP) compared with the population outside? What is the movement and home range and conflict pattern in time and space of tigers and leopards inside the BNP compared with outside? What constitutes…

Uniting an international consortium of scholars, the Skandapurāṇa Project comprises a team of researchers working in fields across the Humanities. We are creating a critical edition of a foundational work of purāṇic literature and, in doing so, tracing the dynamics of a textual tradition to better understand…

Sara Brandellero, Assistant Professor in Brazilian Studies (LUCAS), is a founding member of the newly launched European Network of Brazilianists working in Cultural Analysis/Rede Europeia de Brasilianistas de Análise Cultural – REBRAC. Network launched at international conference at the University of…

1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

Course, Introduction to Dialectometry (2024)

This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

Biodiversity and trade: mitigating the impacts of non-food biomass global supply chains.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

Using biomethane to produce ammonia, a crucial chemical in agriculture, could drastically reduce the climate impact of the process. In a study published in One Earth, researcher Robert Istrate shows it’s even possible to make ammonia production net-zero or carbon negative.

In the next decades, thousands of wind turbines will be added to the North Sea. Environmental scientist Chen Li identified the most beneficial areas for their construction, focusing on material use, carbon footprint, and environmental impact. His paper was published in Environmental Science & Techno…

How can mega sand nourishments, such as the Sand Motor, be designed and managed for optimal ecosystem services provision ?

Researchers need to work in specialized environments when they work with dangerous bacteria and viruses. These microbes spread easily, so only in labs with a high biosafety levels they can be studied. Unfortunately, to look at the microbes properly, expensive microscopes are needed that are not always…

From 26 to 28 May, second-year students of the Advanced MSc International Relations and Diplomacy (MIRD) participated in the programme's annual visit to Geneva, Switzerland.

This new article by Bassant Hassib and James Shires is part of a special issue for Journal of Cybersecurity, based on a selection of contributions from THe Hague Program for Cyber Norms' 2019 Conference.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Do general practitioners recognize children with or at risk of problematic anxiety and is there a pattern that might help differentiate those with and without anxiety disorders in general practice?
