Situation analysis on the integration of refractive error services provided by optometrists into the national health services in Kenya

BMC Public Health
Introduction Even though the burden of uncorrected refractive error could potentially be addressed through innovative and cost-effective approaches, integration of the services into the National Health Services (NHS) is desirable.

Rapid estimation of concentration of aromatic classes in middistillate fuels by high-performance liquid chromatography [PDF]

An high performance liquid chromatography (HPLC) method to estimate four aromatic classes in middistillate fuels is presented. Average refractive indices are used in a correlation to obtain the concentrations of each of the aromatic classes from HPLC ...

Visual acuity standards for driving [PDF]

, 2015
This paper reviews the current visual acuity standards for UK drivers. These standards have changed in recent years such that car drivers (Group 1) now have two standards to meet: reading a number plate at 20m, and achieving an acuity of 6/12.

Demonstration of analyzers for multimode photonic time-bin qubits

, 2018
We demonstrate two approaches for unbalanced interferometers as time-bin qubit analyzers for quantum communication, robust against mode distortions and polarization effects as expected from free-space quantum communication systems including wavefront ...

Amblyopia [PDF]

, 2016
Amblyopia is, aside from refractive error, the most common cause of visual loss in children. Thus amblyopia is a serious public health issue. When diagnosed and treated early, the visual losses may be easily reversed.
