Ultraviolet germicidal irradiation

At this point, it is important to note that, this particular orientation of rhodopsin in the microvillar membrane which gives selective sensitivity to polarized light by itself is not sufficient to analyse the sky 's polarization. An interesting analogy to spectral vision may be stated at this point to make this concept clearer, just like how it would be impossible to detect various colours if only one colour pigment was present, it is equally impossible to analyse the sky 's polarization if the…

Defining healthy sun exposure and sunscreen’s role Most cancer rates are decreasing, whereas skin cancer continues to steadily increase as it has for the past decades (Saraiya et al. 422). The three most common skin cancers are squamous-cell, basal-cell and melanoma carcinomas. Squamous-cell and basal-cell carcinomas are grouped as non-melanoma cancers. Family history and genetic disorders increases the risk of forming cancer; however, estimates place excessive sun exposure as causing as much…

The Banana Boat app would be planned to be released in April of 2017.

Skin cancer is by far known to be the most common type of cancer occurring in the human population today. However, most types of skin cancer are not considered to be a highly epidemic and can be cured easily, but there is one type of skin cancer that is considered to be most life threatening and that is melanoma. The reason why this disease is called ‘melanoma’ is because a tumor develops made of the melanocyte cells which are melanin producing cells (Skin Cancer 2016). Over the past few years’…

beneficial. Sunlight is needed for Vitamin D and energy, but the sun also produces Ultraviolet-A (UVA) and Ultraviolet-B (UVB) rays that can harm the body. Even though the sun’s rays can do damage to the body, many Americans choose to tan. According to skincancer.org, nearly 30 million Americans choose to tan indoors with the use of tanning beds. Like the sun, tanning beds also produce harmful UV-A and UV-B rays. Ultraviolet (UV) radiation from tanning beds can have many negative effects on the…

melanin in our skin the darker our skin colour is. Homo sapiens originally had a white-pink skin colour and they were covered in hair. Over time we grew less and less hair on our bodies resulting in less protection from the sun and its harmful ultraviolet (UV) radiation. In the very northern or southern countries, areas further away from the equator, there is less exposure to UV radiation due to its position. This resulted in people having lighter skin and due to these areas being colder people…

As the authors of “Skin Deep” state, “Our variation in skin color should be celebrated as one of the most visible manifestations of our evolution as a species.” I hope to enlighten you as to why they give creedence to that statement. It boils down to the authors concluding that various elements of natural selection, including reproductive health and migration, as well as cultural behaviors have influenced the variety of skin colors that we see today. To start with, the melanin in our skin…
