(Ablation, NCI Dictionary) Bone marrow ablation followed by replacement of stem cells in the circulating blood to help the bone marrow recover and continue producing healthy blood cells. Ablation - The melting of the ice, mainly during summer months, and usually at the snout end of the glacier.. Accumulation - The build up of the glacier due to snow being compacted into ice.. Calving - The splitting of the end of the glacier into smaller sections.
Abrasion generally occurs four ways. Abrasion : Abrasion is the degeneration of land due to ‘scouring action of materials’. This is a slow process. See Full Answer. 2. removal, especially by cutting with a laser or electrocautery. d. d. d . Ablation. Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. This causes various processes of melt, or ablation, to occur. This can occur through melting or sublimation and, at or near the snout of a glacier, it can also occur by calving. Ablation meaning and definition of ablation ... Google key word : ablation .

Cardiac ablation is a procedure that can help people who have abnormal rhythms in their heart. As a glacier moves, it erodes away at the land surrounding the ice. The annual equilibrium line separates the accumulation and ablation zone annually.

What is a ablation in geography?
Ablation . In many cases, the material located between a moving glacier and its bedrock bed is severely sheared, compressed, and “over-compacted.” This type of deposit is called lodgment till. Estuary Somewhat enclosed coastal area at the mouth of a river where nutrient rich fresh water meets with salty ocean water.
An estimator is any value calculated from the sample data For example, the sample mean is an estimator of the population mean. See more. Ablation may be performed by surgery, hormones, drugs, radiofrequency, heat, or other methods.
