A Qualitative Evidence Synthesis to Explore Relationship‐Centred Dental Care for Older People Living in Care Homes

Gerodontology, EarlyView.
ABSTRACT Background Patient groups and policymakers are calling for the implementation of relationship‐centred, co‐ordinated care for vulnerable older people. Relationship‐centred care highlights the significance of strong, quality relationships among residents, their families and the broader healthcare team.

Solution of Linear Radiative Transfer Equation in Hollow Sphere by Diamond Difference Discrete Ordinates and Decomposition Methods

Semina: Ciências Exatas e Tecnológicas
In this article, we present a methodology to solve radiative transfer problems in spherical geometry without other forms of heat exchange. We use a decomposition method based on the Adomian formulations, together with a diamond difference scheme and a ...

ACS Algorithm in Discrete Ordinates for Pressure Vessel Dosimetry

EPJ Web of Conferences, 2016
The Adaptive Collision Source (ACS) method can solve the Linear Boltzmann Equation (LBE) more efficiently by adaptation of the angular quadrature order. This is similar to, and essentially an extension of, the first collision source method.

A non-separable stochastic model for pulse-like ground motions [PDF]

, 2013
A phenomenological non-separable non-stationary stochastic model is proposed to represent near-fault pulse-like ground motions (PLGMs) by means of a parametrically defined evolutionary power spectrum (EPSD). Numerical data pertaining to ensembles of EPSD
