Article Synopsis
- The work aims to establish equations connecting exposure time to solar radiation, the ultraviolet index (UVI), and their effects on vitamin D synthesis and sunburns.
- It introduces PROBIT equations to predict how much vitamin D various skin types (I to IV) can produce based on repeated sun exposure and protective measures.
- The findings suggest that balancing skin exposure can help achieve required vitamin D levels of 2000 IU or more while minimizing the risk of sunburn, particularly by adjusting the area of skin that is exposed.
The objective of this paper is to propose a methodology to estimate the consequences to buildings from the pressure wave caused by unconfined vapour cloud explosions (VCEs). This methodology is based on the use of characteristic overpressure-impulse-distance curves, shown in a previous paper [F. Diaz Alonso, E.
View Article and Find Full Text PDFA number of models have been proposed to calculate overpressure and impulse from accidental industrial explosions. When the blast is produced by ignition of a vapour cloud, the TNO Multi-Energy model is widely used. From the curves given by this model, data are fitted to obtain equations showing the relationship between overpressure, impulse and distance.
