Nothing in FAR and no standard FAR clause authorizes a CO to unilaterally update, add, or delete clauses in a contract after award. None of the five Changes clauses, FAR 52.243-1 through -5, empower a CO to do that. Thus, with a few exceptions, which are discussed below, changes to FAR clauses â revisions, additions, and deletions â must be accomplished through supplemental agreement [(bilateral modification). See FAR 43.103(a)(3).
What else do I need to know about rib fractures? Flail chest occurs if 3 or more of your ribs are broken in 2 or more places. This condition may make it hard for you to breathe. Normally, when you take a breath, your rib cage expands. Flail chest prevents your ribs from expanding. This can cause your broken ribs to push inward on your organs. What are the signs and symptoms of a rib fracture? Chest wall pain that worsens when you breathe, move, or cough
Both men and women have 24 ribs, twelve on each side. Each rib is attached to a spinal bone (thoracic vertebra) in the back. The first seven pairs of ribs join the breastbone (sternum) in the center of the chest. The front ends of the eighth, ninth, and 10th pairs are connected to the ribs above them. The 11th and 12th pairs are called âfloating ribs,â because they are anchored in place only by connective tissue. One in every few hundred people have an extra rib. These are called cervical ribs, because they arise from one of the spinal bones in the neck (cervical vertebrae).
