The observables of supergravity are defined to be the phase space gauge invariant objects of the theory. Dirac eigenvalues are obsevables of Euclidean gravity on a compact manifold [1,2,3]. We resume the basic results for supergravity [4,5], [6,7]. The general setting which we consider is of minimal supergravity in four dimensions on a compact spin manifold(More)
BACKGROUND The systemic antimicrobial prophylaxis is the standard treatment in the prevention of osteomyelitis after open fractures, with topical application of antimicrobials as an alternative due to their high concentrations at the site of the fracture, low systemic concentrations and fewer side effects. OBJECTIVES This study aimed to evaluate the(More)
