Dentine bond strength of a composite resin polymerized with conventional light and argon laser
Lasers argon Composite resins Dentin Tooth
2009/10/20
The use of argon laser (488 nm) has been suggested as a new alternative for polymerizing adhesive materials. This study aimed to evaluate the tensile bond strength of a microfilled composite (A110, 3M...
Changes in rat respiratory behavior under varying PCO2 levels and argon content in hyperbaric Ar-O2-CO2 atmospheres
respiratory carbon dioxide argon animal rat
2009/7/20
An anesthetized rat preparation has been used for breathing studies in hyperbaric Ar-O2-CO2 atmospheres in which total saturation pressure was varied in the range 1-19.1 ATA and PCO2 was set at levels...
Solubility of helium,argon,and sulfur hexafluoride in human blood measured by mass spectrometry
human helium argon
2009/7/17
A method has been developed to measure the solubility coefficients of gases in liquids by respiratory mass spectrometry. A sample (2.5 ml) pf the test liquid, equilibrated with a test gas mixture, is ...
Thermal insulation properties of argon used as a dry suit inflation gas
argon cold dry air thermal protection
2009/6/5
Uncontrolled observations from the "technical" diving community claim superior thermal comfort when replacing air with argon as dry suit inflation gas during diving. The objective of the present exper...
The purpose of this study is to evaluate the success rate and safety of argon laser photocoagulation as a modality of treatment for symptomatic trichiasis in a Middle Eastern country (Jordan). this si...
