In de afgelopen jaren is er steeds vaker gezocht naar nieuwe methodes om het klimaat van het verleden te kunnen reconstrueren. Voor temperatuur bepalen wordt er onderzocht of Mg isotoop ratio’s hier een indicator voor kunnen zijn. Het verschil tussen twee isotoop ratio’s wordt uitgedrukt in de delta …

Objective: There are widespread shortages of personal protective equipment as a result of the COVID-19 pandemic. Reprocessing filtering facepiece particle (FFP)-type respirators may provide an alternative solution in keeping healthcare professionals safe. Design: Prospective, bench-to-bedside. Setting: …

On duty, police officers are exposed to a variety of acute, threatening stress situations and organizational demands. In line with the allostatic load model, the resulting acute and chronic stress might have tremendous consequences for police officers’ work performance and psychological and physical …

Shared leadership is viewed as an effective form of management to deal with increased complexity in youth team sport. However two gaps exist: ‘lack of literature concerning leadership development in youth’ and ‘the paucity of reliable and valid measures to assess shared leadership in youth sport’. This …

DNA-based identification through the use of metabarcoding has been proposed as the next step in the monitoring of biological communities, such as those assessed under the Water Framework Directive (WFD). Advances have been made in the field of metabarcoding, but challenges remain when using complex samples. …

In this project, we investigated how the visual vernacular of climate change, defined as the platform-specific content and style of images used to articulate climate change, changed on Twitter between 2016-19. Due to the high number of tweets in the dataset, we focused on smaller time-specific samples …

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 …

During this research project the influence of selenium enriched growing environment on the phenolic composition on several Allium species is studied. Besides this, the influence on morphological properties is also monitored. Folin-Ciocalteu method is used to determine the total phenolic content and High …

A method for directly analysing the nickel content of organic samples by flame atomic absorption is validated. This method is developed to bypass the conventional preparation step for aqueous atomic absorption, which is microwave digestion. The working range of the method is 0 – 30 ppm. The limits of …
