The waterâs temperature affects the dissolved oxygen capacity of the water. The ratio of the dissolved oxygen content to the potential capacity of the water gives the percent of saturation, which is an indicator of water quality.Since temperature fluctuates during each day and according to the seasons of the year, dissolved oxygen levels also fluctuate accordingly (Gada 2010).he ratio of the dissolved oxygen content to the potential capacity of the water gives the percent of saturation, which is an indicator of water quality.

Tailbone Pain During Pregnancy â Causes and Treatment. Tailbone Pain (Coccyx Pain, Coccydynia) Location and Symptoms. Tailbone pain is a sharp or dull pain on the end of the spine â in the lower back between the upper buttocks (Picture 1). The pain can be severe; some women describe it as a âbruised tailboneâ.
Symptoms may include difficulty with sitting, pain with deep penetration during intercourse (for women), constipation and even severe headaches. Some people also report concurrent back pain. A fall, surgery or accident can move the tailbone out of its normal place, causing constipation, tailbone or lower back pain. In all of these situations, the coccyx may be pushed into an awkward angle. The consequent pull on support ligaments and nerves can cause moderate to debilitating tailbone pain.
