Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

Development of an aggregated impact indicator to measure decoupling.

SEAtrans: an interdisciplinary research project that aims at studying the dynamics and processes of transitions in society-nature interactions in Southeast Asian societies.

Op 10 november 2021 verdedigde Carmel van Niekerk-Jacobs het proefschrift 'Realising the right to reproduce with assistance in South Africa'. Het promotieonderzoek is begeleid door prof.dr. J.J. Sloth-Nielsen en prof.dr. T. Liefaard.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Evaluating the environmental consequences of diet changes in the European Union.

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

The Dutch atlas with pesticides concentrations in surface waters have been overhauled. This new, free accessible, website is in line with the European Framework Directive on Water (In Dutch: KRW).

What are the environmental trade-offs for SMEs considering moving from monoculture aquaculture practice towards IMTA? What are the environmental trade-offs comparing IMTA species with their conventional monoculture alternatives?

In deze masterspecialisatie volg je naast de Nederlandstalige kerncursus en scriptieseminar een aantal Engelstalige vakken en keuzeseminars. In het programma is naast de politiekwetenschappelijke inhoud ook aandacht voor onderzoeksvaardigheden.

Security is key to survival for any living organism: life is full of perils and threats, both physically, environmentally, and societally. Security challenges such as terrorism, natural disasters, and cybercrime rank among the most pressing issues of our time, affecting the security and safety of millions…

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

Although nanoparticles are extensively used in various applications like consumer products and have most probably entered the environment, little is known about the effects of these particles on living organisms.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.
