LEAVE ACCRUAL RECORDS. Vacation and sick leaves are accrued based on the leave accrual codes established on the Payroll Personnel System (PPS). Leave code is established by the department when an appointment is initially set up. For staff employees thereafter, the PPS will re-derive the leave code on the appointment during month-begin periodic maintenance.
For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction.
A diminished blood supply means that heart muscle cells receive less oxygen and nutrients needed to function optimally and waste products manufactured is not drained away in an efficient manner.
