Synchrotron X-ray diffraction characterization of healthy and fluorotic human dental enamel

open access: yes, 2020
With the introduction of fluoride as the main anticaries agent used in preventive dentistry, and perhaps an increase in fluoride in our food chain, dental fluorosis has become an increasing world-wide problem.

Wave loadings on a vertical cylinder due to heave motion

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
Wave forces and moments due to scattering and radiation for a vertical circular cylinder heaving in water of finite depth are derived analytically. These are derived from the total velocity potential which can be decomposed as two velocity potentials ...

On the complete radiation-diffraction problem and wave-drift damping of marine bodies in the yaw mode of motion [PDF]

open access: yesJournal of Fluid Mechanics, 1998
The coupled radiation-diffraction problem due to a floating body with slow (time-dependent) rotation about the vertical axis in incoming waves is studied by means of potential theory. The water depth may be finite. First, the radiation problem is described.

Application of Laboratory Diffraction Methods in Characterization of Elements Made By Additive SLM Methods – State of the Art

open access: yesFatigue of Aircraft Structures, 2021
The greatest challenge of widely developed incremental manufacturing methods today is to obtain, as a result of the manufacturing process, such components that will have acceptable strength properties from the point of view of a given application.

Diffraction by a half-plane in a moving fluid

open access: yes, 2005
In the following work we solve the problem of the diffraction of a plane sound wave by an impedance half-plane in a moving fluid. Expressions for the total far field are derived for both the leading edge and trailing edge situations. In the trailing edge

PROSPECTS OF THE USE OF GRADIENT GRATES IN THE LASERS OF TERAHERTZ RANGE [PDF]

open access: yesRadio Physics and Radio Astronomy, 2018
Purpose: The improvement and development of terahertz radiation sources is required for the further development of the terahertz frequency range. Submillimeter lasers are one of the few sources of terahertz radiation.
