The goal of this thesis is achieving saturation intensity of 76.5 mW/cm2for 2S1/2F=1 - 2P1/2F = 2 transition in singly-ionized beryllium ions (Be+). By enlarging the optical power of a laser diode at 626.266 nm via a bow-tie cavity and converting to 313.133 nm using Second Harmonic Generation in a nonlinear …

As an essential nutrient for food production, phosphate is largely used in fertilizers to enhance crop growth (Baishya et al., 2016; Hasanuzzaman et al., 2018). Regardless of its enormous demand, the only concentrated P source is phosphate rock and the resource is finite (Cordell & White, 2011; Smit …

Lower cardiorespiratory fitness (CRF) and physical activity (PA) associate with higher cardiovascular disease (CVD) risk, but the relationship between CRF and PA in people who have rheumatoid arthritis (RA) at an increased CVD risk (CVD-RA) is not known. The objectives of this study were to determine …

Police interrogations tend to be very stressful which comes at the expense of the effectiveness of interrogations as stressed suspects and witnesses provide less extensive and accurate statements. To study the contribution of the interrogation room towards this problem, an experiment using the four-group …

Background: The Clinical Frailty Scale (CFS) is frequently used to measure frailty in critically ill adults. There is wide variation in the approach to analysing the relationship between the CFS score and mortality after admission to the ICU. This study aimed to evaluate the influence of modelling approach …

Information about the sources of plastic litter found in the Zeeuwse Delta is still scarce. This problem is addressed by this study with the aim to identify the possible sources of plastics that washed ashore on a selection of beaches in the Zeeuwse Delta. For this study the source and origin of the …

Heatwaves are expected to increase in the future due to climate change. Heatwaves cause heat stress to humans and some of the effects are dehydration and hyperthermia. In general it is known what can be done to reduce heat stress. However, applying this knowledge on a local scale requires a clear overview …
