Photodynamic Therapy (PDT) in Prosthodontics: Disinfection of Human Teeth Exposed to Streptococcus mutans and the Effect on the Adhesion of Full Ceramic Veneers, Crowns, and Inlays: An In Vitro Study

open access: yesBiomedicines, 2022
The use of PDT in prosthodontics as a disinfection protocol can eradicate bacteria from tooth surfaces by causing the death of the microorganisms to which the photosensitizer binds, absorbing the energy of laser light during irradiation.

Statistical approach on the inter-yarn friction behavior of the dual-phase STF/ρ-Aramid impregnated fabrics via factorial design and 3D-RSM

open access: yesHeliyon, 2023
Shear thickening fluids (STFs) refer to non-Newtonian fluids of the dilatant variety, wherein their viscosity experiences a significant surge with an escalation in the shear rate. In this investigative work, the friction behavior between yarns (pull-out)

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Development of compression pull-off test (CPOT) to assess bond strength of bitumen

open access: yes, 2019
The quantification of moisture susceptibility has been a major concern for researchers as it adversely affects the performance of asphalt pavements. Several methods have been developed to assess bond strength using asphalt mixtures in loose and compacted

An approach to harmonic load- and source-pull measurements for high-efficiency PA design [PDF]

open access: yes, 2004
High-efficiency power-amplifier design requires numerous efforts to investigate both input and output harmonic terminations effects. A simplified theoretical approach to clarify the relevance of such terminations is presented here, and design criteria to

Determination and modelling of bond properties of synthetic macro-fibres in concrete

open access: yesMokslas: Lietuvos Ateitis, 2021
Bond behaviour of a synthetic macro-fibre in concrete is the object of this research. The bond strength and stiffness are the parameters characterising the bonding mechanism that determines the efficiency of the reinforcing material. However, there is no

Modelling of clinching joint pull-out test

open access: yesComputer Methods in Materials Science, 2015
The paper presents the model of the tests on joints obtained by clinching (mechanical joining) high-strength TRIP690 steels. A numerical finite element analysis of the joint with a bottom thickness of 0.6, 0.7 and 0.8 mm was carried out using the MSC.MARC&MENTAT implicit software.
