Answer to Question 1

Tower shading can cause the blades to flex slightly as they pass the tower, creating stress in the blades. In addition to potential damage, flexing can produce an oscillation.

Answer to Question 2

Line current is measured on a given line; phase current is measured on a component within the three-phase wye or delta connection. Line current and phase current are the same in the wye connection.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
