The influence of blood glucose level on tear break up time among young adults with diabetes [PDF]

open access: yes, 2018
It has been reported that diabetics are more likely to develop tear film dysfunction compared to non-diabetics. Even so, there has been very little research reported on the correlation between blood glucose level and quality of tears.

Tear break-up time for tear film evaluation: Are moistening solutions interchangeable?

open access: yesContact Lens and Anterior Eye, 2015
It was the main purpose of this study to investigate the influence of the moistening solution on TBUT measurements in an asymptomatic population.An online survey was employed to determine the compliance of Spanish eye care practitioners with the recommended normalized procedure to administer TBUT.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...
