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.
Without an adequate blood supply, the heart muscle is deprived of oxygen and nutrients and waste products manufactured by the cells accumulates in the muscle tissue. Depending on the severity, it may cause myocardial ischemia, which is damage but not death of the muscle due to an inadequate blood supply. Alternatively it may cause death of the muscle tissue which is known as a myocardial infarction (MI).
