    Notes: Abstract In the absence of underlying lung disease, pneumothorax is a rare complication of open heart surgery in patients on cardiopulmonray bypass. However, barotraumatic pneumothoraces may be induced by manually applied endotracheal tube positive pressure to prevent air emboli from the left heart during open heart surgery. Two patients in whom barotraumatic pneumothoraces occurred during cardiopulmonary bypass and open heart surgery are reported.

    Notes: Summary The relation of worker size to ommatidia number was examined in the polymorphic antCamponotus pennsylvanicus (DeGeer). Linear regression described this relationship as:Y = 260.9 + 113.6×; whereYis ommatidia number andX is head width. A log-log regression described this relationship as:Y = 323.5 + 286.9*logX(r 2 = 0.98). This analysis indicated an allometric relation of ommatidia number to head width, where ommatidia numbers increase at a slower rate than head width. This relationship is discussed in terms of ethotypes associated with worker morphotypes, and the possible mechanisms regulating polymorphic development.
