Evaluation of Tear Fluid and Aqueous Humor Concentration of Clusterin as Biomarkers for Early Diagnosis of Pseudoexfoliation Syndrome and Pseudoexfoliative Glaucoma
(Taylor and Francis Ltd, 2.07.2020)Purpose: Pseudoexfoliation syndrome (PEX) is an age-related disorder of the extracellular matrix characterized by the accumulation of fibrillary deposits in the anterior chamber of the eye, which leads to the development ... -
Aircraft Structural Safety : Effects of Explicit and Implicit Safety and Measures Uncertainty Reduction Mechanisms
(University of Florida, 2006)Aircraft structural safety is achieved by using different safety measures such as safety and knockdown factors, tests and redundancy. Safety factors or knockdown factors can be either explicit (e.g., load safety factor of ... -
The frictional contact problem of sliding rigid parabolic stamps on graded materials
(2008-02)This study presents an analytical procedure to determine the contact stress distribution at the surface of an FGM coating perfectly bonded to a homogeneous substrate. The coating is assumed to be loaded by a rigid stamp ... -

Mesoscopic nonequilibrium thermodynamics treatment of the grain boundary thermal grooving induced by the anisotropic surface drift diffusion
(Springer, 2011-09)A systematic study based on the self-consistent dynamical simulations is presented for the grain boundary thermal grooving problem by strictly following the irreversible thermodynamic theory of surfaces and interfaces with ... -
Peptides to bridge biological-platinum materials interface
(Ice Publishing, 2012)Peptides with inorganic materials recognition already started to impact a wide range of surface- related technologies ranging from biomonitoring to biomedical areas. Combinatorial biology- based libraries are the initial ... -
Grain boundary grooving in bi-crystal thin films induced by surface drift-diffusion driven by capillary forces and applied uniaxial tensile stresses
(Taylor & Francis Ltd, 2012)Grain boundary (GB) grooving, induced by surface drift-diffusion and driven by the combined actions of capillary forces and applied uniaxial tensile stresses, is investigated in bi-crystal thin films using self-consistent ... -
Dynamic server allocation for unstable queueing networks with flexible servers
(Springer, 2012-01)This paper is concerned with the dynamic assignment of servers to tasks in queueing networks where demand may exceed the capacity for service. The objective is to maximize the system throughput. We use fluid limit analysis ... -
A criterion for the onset of void coalescence under combined tension and shear
(Pergamon-Elsevier Science Ltd, 2012-07)Depending on the relative positions of voids and on the loading conditions, shear loading components can play an important role in the void coalescence process leading to ductile fracture. Yet, most void coalescence criteria ... -
