Introduction After walking into an optician store one day, not knowing what to try on, bad customer service and becoming exhausted after trying on all the sunglasses in the store, the idea of a selfie application came to me. The application would be a fun tool for people in need of help of finding the right shape that would fit their face shape. Been in the optician business for eight years, I talked to the department of marketing at Synsam Norway, and they were interested in the idea. This is a…

Ozone is a naturally occurring molecule containing three oxygen atoms. Ozone molecules form a gaseous layer in the stratosphere, 15-30 km above the surface of the earth called the Ozone layer. It protects life on earth by absorbing harmful ultraviolet (UV) radiation from the sun. Today the ozone layer is depleting due to the release of pollution containing chemicals chlorine and bromine. Such deterioration allows large amounts of UV B rays to reach Earth1 seen in figure 1, which can cause many…

There are several forms of skin cancer including; Squamous cell skin carcinoma, Basal cell cancer, and Melanoma, the deadliest form of cancer. It’s evident that ultraviolet (UV) rays are a major cause of melanoma. The UV rays damage the DNA in skin cells and sometimes this damage can affect certain genes, which control how skin cells grow and divide. If these genes become affected, they’re no longer able to function…

Mutations of Penicillium notatum When Introduced to Ultraviolet Radiation in Different Environments Introduction DNA is composed of two strands composed of polynucleotides arranged in a double helix formation composed of four nucleotide subunits: adenine (A), thymine (T), guanine (G), and cytosine (C). Each base must form a hydrogen bond with its respective compatible base, therefore adenine always bonds with thymine and guanine always bonds with cytosine. DNA is used to…

really worth shortening your life span? Having a sun kissed glowing tan has been known to not only improve your overall confidence and self-esteem but to make you feel instantly happier and help you get over your post-holiday blues. Sunbeds give out ultraviolet (UV) rays that can damage your skin not only in short term but also long term. These UV rays can cause your skin to age a lot quicker than it naturally would causing early wrinkles and make it look leathery, it can also cause your body’s…

Accordingly, the purpose of the experiment is to determine what the effect of UVA light is on Staphylococcus epidermidis. The hypothesis for this experiment is if the exposure of the ultraviolet light wattage increases, then the growth of staph will decrease when the growth of staph is a function of ultraviolet light. Moreover, the almost all of same form of UV light will be used. The three sources of UV light will be sunlight, which has a mixture of UVA and UVB light, tanning light, and black…

was then placed in either ampicillin or not as well as with a ribosome known as arabinose. The E. coli without pGLO died in the ampicillin and the ones with pGLO survived after a period of incubation, with the one that had arabinose glowing under ultraviolet light. This was the expected result due to GFP adding a resistance to ampicillin in the plasmid. Introductions Escherichia coli…

common and primary cause of skin cancer such as from the sun or from chemicals,Because the sun gives off three types of electromagnetic radiation that are close to skin cancer. UVB is the most damaging of the uv bands. UVB means the spectrum of the ultraviolet region, and when you get too much of ultra violet rays from the sun, that's when you get skin cancer. If you want to maybe spend more than 3 hours in the sun, you need some serious protection against those rays of the sun. You should use…

“CHM 110 Required Note Packet.” This chart shows a spectrum from gamma rays to radio waves. Gamma rays, in which, are high energy radiation, and radio waves, which are low energy radiation (Kudurna “CHM 110 Required Note Packet”). For example, “Ultraviolet light is a type of high radiation that can be damaging to the body (Kudurna “CHM 110 Required Note Packet”).” Normally UV rays are blocked by suncreens, but with the invention of this new apparel, that can support the body to remain cool…
