You may notice that your menstrual blood becomes dark brown or almost black as you near the end of your period. This is a normal color change. It happens when the blood is older and not being expelled from the body quickly. Temporary thick, heavy flow isn't necessarily cause for concern.hen, during your period, your body sheds the uterus lining along with blood. The amount of blood and fluid lost is usually between 4 and 12 teaspoons each cycle. The average menstrual cycle lasts 28 days (counting from the first day of bleeding to the first day of the next cycle).
Depreciation is the process by which a company allocates an asset's cost over the duration of its useful life. Each time a company prepares its financial statements, it records a depreciation expense to allocate a portion of the cost of the buildings, machines or equipment it has purchased to the current fiscal year.
Understanding accumulated depreciation is impossible without understanding depreciation. Depreciation is the reduction of the value of a fixed asset over a pre-defined period of time. For example, the value of a piece of machinery worth $10,000 at purchase may depreciate by $1,000 per year over a period of 10 years.
