31. Similarly, the PTAA model makes repeated calculations of mass balance , minutely re-adjusting the balance for each iteration. 32. Mass balanced ailerons, narrower than those of the Streak filled more than half of the trailing edge.33. Investigations were carried out by ARL and a split mass balance arm was fitted to each rudder. 34. Long-term mass balance records from Lemon Creek Glacier in Alaska show slightly declining mass balance with time. 35. Long-term mass balance records from Lemon Creek Glacier in Alaska show slightly declining mass balance with time. 36. The mass balance between sediment being transported and sediment in the bed is described by the Exner equation. 37. Dyurgerov, M . B ., 2002 : Glacier Mass Balance and Regime : Data of Measurements and Analysis. 38. The tail-unit also had fabric covered control surfaces, and trim tabs, with all controls 100 % mass balanced . 39. To determine mass balance in the accumulation zone, snowpack depth is measured using probing, snowpits or crevasse stratigraphy. 40. The health of a glacier is usually assessed by determining the glacier mass balance or observing terminus behavior.
