This paper describe the spaces spanned by the angle sums of certain classes of polytopes, as recorded in the α-vector. Families of polytopes are constructed whose angle sums span the spaces of polytopes defined by the Gram and Perles equations, analogs of the Euler and Dehn-Sommerville equations. This shows that the dimension of the affine span of the space of angle sums of simplices is ⌊ d−1 2...

We review several linear algebraic aspects of the DehnSommerville relations and relate redundant analogues of the f and h-vectors describing the subsets of a simplex 2 that satisfy Dehn-Sommerville type relations to integer points contained in some rational polytopes.

Abstract We aimed to monitor the adverse effects (AE) and efficacy of post exposure prophylaxis (PEP) in health care workers (HCWs) exposed a rabies patient. In this study 109 HCWs eight household contacts were PEP candidates . Contact persons without infection control precautions Group I (high risk-82 cases). indirectly environmental surfaces classified II (low risk-35 schedule was vaccine (RB...

BACKGROUND Internet-based cognitive behavioural therapy (iCBT) for depression is effective when guided by a clinician, less so if unguided. QUESTION Would guidance from a technician be as effective as guidance from a clinician? METHOD Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based voluntee...

Fatigue has long been identified as a human factor in aviation. Subsequently, series of studies have highlighted fatigue-related elements within the context aviation industry, focusing on flight deck – with some extension to students and maintenance activities. However, latter not deeply examined its crew-centered counterpart. Similarly if more significantly fatigue experienced by aircraft tech...
