The recommended dose and schedule of nivolumab in adjuvant melanoma is 240 mg administered as an IV infusion over 60 minutes every two weeks until disease recurrence or unacceptable toxicity, for a maximum of 1 year.
The velocity of a skydiver is largely governed by weight and drag. Obviously both can vary quite a bit. The typical skydiver flying in belly or prone position reaches the terminal velocity of about 110mph to 150mph (typically 130mph) after about 1000ft of freefall.
Raindrops are larger. A large raindrop, about one-quarter of an inch across or about the size of a house fly, has terminal fall speeds of about 10 meters per second or about 20 mph. That kind of speed can cause compaction and erosion of the soil by their force of impact.
