Payroll time conversion is simply the process of converting minutes to hours for payroll purposes. For example, 30 minutes would be entered into payroll as 0.5 hours. Some organizations only enter a single decimal for hours, so minutes are rounded. If only a single decimal place is used, typically organizations will round up.
A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath. Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality.
A long-standing hypothesis is that yawning is caused by an excess of carbon dioxide and lack of oxygen in the blood. The brain stem detects this and triggers the yawn reflex. The mouth stretches wide and the lungs inhale deeply, bringing oxygen into the lungs and hence to the bloodstream.s such, the stretching of jaw and face muscles seems to be necessary for a good yawn.The yawn reflex is often described as contagious: if one person yawns, this will cause another person to sympathetically yawn. The reasons for this are unclear; however, recent research suggests that yawning might be a herd instinct.
