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.
Defining Depreciation and Depreciation Rate. The depreciation rate is the percent rate at which an asset is depreciated. A company determines the depreciation rate by dividing the depreciated cost of an asset by the number of years of its useful life. Depreciation is the periodic transfer of cost to expense. It applies to fixed assets, which lose their ability to provide services over time. Fixed assets include buildings and equipment.
