The age estimation of biological traces is one of the holy grails in forensic investigations. We developed a method for the age estimation of semen stains using fluorescence spectroscopy in conjunction with a stoichiometric ageing model. The model describes the degradation and generation rate of proteins …

Since the return of the grey wolf (Canis lupus) in the Netherlands in 2015, much research has been done on the ecology and distribution of the species. This has led to a dietary study using hair- and DNA-sampling of wolf scats, and preliminary analyses of DNA in wolf scats showed that DNA from non-prey, …

This collection of articles contains contributions to the research project ‘From Prevention to Resilience’ (FPtP). In this project, the research team has generated insights and tools for designers, policymakers, and other professionals to contribute to more resilient cities and neighborhoods. The point …

Microbial spoilage by moulds is a major quality challenge for bread manufacturers. It reduces the product shelf-life generating economic losses and consumers dissatisfaction. In particular, bake-off bread products are susceptible for mould formation. Mould growth is mainly caused by mould aerosols, contaminating …

We report the detection of tryptophan at sub-ppb levels for a fluorometer based on Fresnel lenses and low-cost electronics. These fluorometers can be used to detect fecal contamination in drinking water, indicated by tryptophan-like fluorescence.

Background People from lower and middle socioeconomic classes and vulnerable populations are among the worst affected by the COVID-19 pandemic, thus exacerbating disparities and the digital divide. Objective To draw a portrait of e-services as a digital approach to support digital health literacy in …

Every year, an average Dutch household produces 1165 kilogram of waste. For high-quality recycling of this waste, we need to separate the waste properly, as placing something in the wrong container may jeopardize the whole recycling process. Municipalities are keen to increase the amount of waste that …

Soil quality is directly linked to food quality and quantity. However the globalisation and the pressure to increase the agricultural production results to deterioration of the environment, climate change and a serious threat to human and animal health. Soil contamination effected by the environmental …

A growing number of women have paid jobs before and during pregnancy. Thus, increasingly more women are potentially exposed to occupational hazards by working with organic solvents, pollutants, toxins, or contaminated water. Working in these areas can lead to adverse effects on the health of young women …

The use of cleanrooms is increasing and the expectation is that this growth will continue in the coming decade. When compared to an average office building, cleanrooms consume large amounts of energy due to their high Air Change Rates (ACRs) and strict air conditioning requirements. Application of Demand …
