The front panel includes a front panel UV light sensor, a front panel IR phototransistor, and an LCD. The side panel includes a side panel UV light sensor, and a side panel IR phototransistor. A temperature sensor measures a skin temperature and generates a temperature signal. A skin color sensor detects a skin color of the driver and generates a skin color signal. The microcontroller requests an input of a SPF of a sunscreen used by the driver; calculates an exposure time threshold; generates a UV exposure warning when an exposure time exceeds the exposure time threshold; calculates an updated skin temperature; and generates an IR exposure warning when the updated skin temperature exceeds a maximum skin temperature threshold.

Abstract

A method of fixating a tissue sample includes treating the tissue sample having a pre-treatment composition with a propolis-containing composition to form a fixated tissue sample having a post-treatment composition. The propolis-containing composition includes a propolis extract and at least one liquid. The pre-treatment composition comprises a mixture of proteins, nucleic acids, carbohydrates, lipids, minerals, and vitamins. The mixture of nucleic acids, carbohydrates, lipids, minerals, and vitamins in the pre-treatment composition is the same as that in the post-treatment composition.
