BACKGROUND Corneal transplantation has rapidly evolved from full-thickness penetrating keratoplasty (PK) to selective tissue corneal transplantation, where only the diseased portions of the patient's corneal tissue are replaced with healthy donor tissue. Descemet's membrane endothelial keratoplasty (DMEK) performed in patients with corneal endothelial dysfunction is one such example where only ...

This study introduces the free vibration analysis of multilayered symmetric sandwich Timoshenko beams, made of functionally graded materials with two edge cracked, using the finite element method and linear elastic fracture mechanic theory. The FG beam consists of 50 layers, located symmetrically to the neutral plane, whose material properties distribution change along the beam thickness, accor...

This letter reports on the improvement of a SiO2 layer formed by atomic deposition 4H-SiC, using post-deposition anneal in forming gas ambient. Capacitance–voltage measurements revealed good electrical properties, compared to thermal oxide which was grown N2O, with flatband voltage values averaging at -0.29 V and low positive mobile ion charge density order 1010 cm?2. XPS analysis FG annealed s...

This paper introduces the concept of Fg-metric Space. We generalize G-metric space. Some supporting examples are given.

We present a general method to quantify coatings on microparticle surfaces based on the additional mass. Particle buoyant mass is determined in a solution with a density that is nearly equivalent to that of the core particle, reducing the magnitude and uncertainty of the measurement. Under these conditions, added material with a different density than that of the core is a larger fraction of th...

Fibrinogen (Fg) has been recognized to play a central role in coagulation, inflammation and tissue regeneration. Several studies have used Fg deficient mice (Fg(-/-)) in comparison with heterozygous mice (Fg(+/-)) to point the proinflammatory role of Fg in diverse pathological conditions and disease states. Although Fg(+/-) mice are considered 'normal', plasma Fg is reduced to ~75% of the norma...
