Effects of Hip Geometry on Fracture Patterns of Proximal Femur

  Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...

Role of spin state on the geometry and nuclear quadrupole resonance parameters in hemin complex.

Theoretical calculations of structural parameters, 57Fe, 14N and 17 O electric field gradient (EFG) tensors for full size-hemin group have been carried out using density functional theory. These calculations are intended to shed light on the difference between the geometry parameters, nuclear quadrupole coupling constants (QCC), and asymmetry parameters (eta Q) found in three spin states of hem...

Open cavity receiver geometry influence on radiative losses

Open cavity receivers can be used to efficiently absorb concentrated solar radiation at high temperatures. Using ray-tracing and a stochastic optimisation method, the geometry of such receivers is optimised looking at radiative losses only. Results confirm the major role of the aperture in cavity losses mitigation and highlight the flux distribution variation on geometries with comparable radia...

Lectures on complex geometry, Calabi–Yau manifolds and toric geometry

These are introductory lecture notes on complex geometry, Calabi–Yau manifolds and toric geometry. We first define basic concepts of complex and Kähler geometry. We then proceed with an analysis of various definitions of Calabi–Yau manifolds. The last section provides a short introduction to toric geometry, aimed at constructing Calabi–Yau manifolds in two different ways; as hypersurfaces in to...
