If this is a sound wave, the denser the medium, the faster the wave. For a light wave, the denser the medium, the slower the wave. It all depends on the medium through which it travels. The factor of the medium that plays a role on the velocity of a wave is its density. If this is a sound wave, the denser the medium, the faster the wave.
Mastitis is an infection of the tissue of the breast that occurs most frequently during the time of breastfeeding. This infection causes pain, swelling, redness, and increased temperature of the breast. It can occur when bacteria, often from the infant's mouth, enter a milk duct through a crack in the nipple. This causes an infection and painful inflammation of the breast.
Mastitis In Dogs. Mastitis is an infection of the milk ducts. Also called mammitis or mastadenitis, during nursing, it can be caused by a breast (teat) engorgement (swelling).Mastitis can also be caused by a blocked milk duct. You may see cracked or damaged skin or tissue around the nipple.Bacteria get inside, either by a crack or even through the pores, and can infect the dam suddenly, even if the teat is not engorged. An engorged breast is a mild form of mastitis.Mastitis, if not treated, can lead to gangrene mastitis. Gangrene mastitis is caused by bacteria that do not require oxygen in order to grow (anaerobic bacteria). The skin turns black and dies, leaving a huge hole that will drain pus-blood.n engorged breast is a mild form of mastitis. Mastitis, if not treated, can lead to gangrene mastitis.
