Here's what I found a while back when seeking info about tumor necrosis. 1) Necrosis in the tumor means that the cancer cells in that area are dead. The pathologic finding of necrosis suggests a fast-growing cancer. This often happens because the tumor runs out of blood supply in the central portion. Without a blood supply, the tumor cells cannot live.
In association football, where the shoes themselves are known as football boots, there are three different cleat types. There are soft ground cleats which are made for wet weather. The soft ground cleats are always replaceable, and are almost always metal, so when they wear down they are easy to replace.
Artificial turf's stiff plastics and polymer surface is not as forgiving as natural grass, and when you try to pivot or make sharp lateral movements, it grabs your shoe; thus, short cleats, or studs, are best. Cleats measuring 1/2 an inch are called firm-ground cleats. Compared to the 1-inch, soft-ground cleats, the short cleats are less likely to get locked into â or tear up â artificial turf, and allow athletes better mobility and healthier knees.
