A micromechanical four-phase model to predict the compressive failure surface of cement concrete [PDF]
Fracture and Structural Integrity, 2014 In this work, a micromechanical model is used in order to predict the failure surface of cement concrete subject to multi-axial compression. In the adopted model, the concrete material is schematised as a composite with the following constituents: coarse

Deformation behavior of axially compressed aluminum polygonal tube
Procedia Engineering, 2017 Abstract Aluminum tubes are efficient energy absorbing components and are widely used as framework and reinforcement members of structures. This paper deals with the influence of the axial length, cross-sectional shape and reinforcing rib on a dynamic axially compressed aluminum polygonal tube in order to obtain basic data on buckling.

Collective excitations of a degenerate gas at the BEC-BCS crossover
, 2004 We study collective excitation modes of a fermionic gas of $^6$Li atoms in the BEC-BCS crossover regime. While measurements of the axial compression mode in the cigar-shaped trap close to a Feshbach resonance confirm theoretical expectations, the radial ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
