I lived in Switzerland for a year when I was younger. I discovered that my favorite food is deep fried haggis with chips, when I visited Scotland this summer. My favorite book genres are fantasy, science fiction and historical fiction. I love medieval, Jacobite and Renaissance history. I am a big fan of Harry Potter and Lord of the Rings. I love art and music. I play the Irish whistle and piano. I recently got a flute and am working on learning it as well. I also want to learn the bagpipes. My favorite art mediums are chalk pastels, oil paint, clay and ink. I especially like calligraphy. When I finish school and university I would like to be an university professor.

Sommaire:Usnic acid was extracted from Usnea hirta. The extract was transferred into olive oil to create a solution that could be used as sunscreen. The sample was then run through a spectrophotometer to determine UV absorption. These results were used to calculate SPF. The results indicate that a sunscreen is possible, although an increased concentration of usnic acid is required for a reasonable SPF.
