All of the calculations in this section will be worked out using the distance, speed and time equation. An easy way to remember the distance, speed and time equations is to put the letters into a triangle.The triangles will help you remember these 3 rules: 1  Distance = Speed x Time.n the next page there are some examples to work through. Have paper and a pen handy, draw the distance, speed and time triangle on your paper, then try the examples. It might be helpful to first take a look at Bitesize Time Calculations.
Which procedure you have depends on the location, size, and type of lesion. A lesion is an abnormal area of the skin. This can be a lump, sore, or an area of skin color that is not normal. Before a biopsy, your provider will numb the area of skin so you don't feel anything. The different types of skin biopsies are described below.
Skin Abscess Overview. A skin abscess is a localized collection of pus that generally develops in response to infection or to the presence of other foreign materials under the skin. An abscess is typically painful, and it appears as a swollen area that is warm to the touch. The skin surrounding an abscess often appears pink or red. Abscesses can develop in many parts of the body, but they usually involve the skin surface. Skin abscesses are also referred to as boils.
