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 …

Non-invasive, rapid, on-site detection and identification of body fluids is highly desired in forensic investigations. The use of fluorescence-based methods for body fluid identification, have so far remain relatively unexplored. As such, the fluorescent properties of semen, serum, urine, saliva and …

In this research several methods were developed and validated using the Supermini 200 wavelength dispersive X-ray fluorescence spectrometer. A multielement was calibrated containing 26 elements and corrected for interference according to the de Jongh algorithm. The limits of detection and quantification …

Sustainable Urban Drainages Systems (SuDS) are designed to collect, store and infiltrate large amount of surface runoff water during heavy rainfall. Surface runoff water is known to transport pollutants such as particle bound heavy metals. Therefore, a build-up of pollutants in the top-soil, of the commonly …

Er wordt bewuster omgegaan met de bodem om deze, op dit moment en voor de toekomst, niet nadelig te beïnvloeden. Voor agrarisch ondernemers is dit van groot belang. Hierbij ligt de focus op de chemische, fysische en biologische gezondheid van de bodem. Dit onderzoek is afgebakend tot de chemische gesteldheid …

Raman spectroscopy is an optical technique that is based on the inelastic scattering of light. It is non-invasive, fast, objective and easy to use. These traits make it an ideal tool for use in medical diagnosis. Melanoma is the deadliest form of skin cancer. Currently, melanomas are visually diagnosed …
