AbstractPURPOSE: To report observations on the influence of posterior lens capsule opacification on optical coherence tomographic imaging quality and measurements of macular thickness. METHODS: The retrospective study included 13 eyes in 12 patients of which 2 eyes had a healthy macula and 11 eyes had maculopathy. In all eyes posterior lens capsule fibrosis was present. A clinical examination incl

The simulation model for secondary settling tanks by Bürger et al. (2013) was introduced mainly to resolve spatial discretization problems when both hindered settling and the phenomena of compression and dispersion are included. Straightforward time integration unfortunately means long computationaltimes. The next step in the development is to introduce and investigate time-integration methods for

Aims/hypothesis. With ageing the long-lived proteins of the human lens undergo denaturation by non-enzymatic glycation. The denaturated proteins are fluorescent, a property that can be assessed in vivo by fluorometry. Our aim was to examine the relative contribution of hereditary and environmental effects on the accumulation of fluorescent compounds in the lens.Methods. We examined 59 monozygotic

This contribution introduces a new perspective on the modelling of settling behaviour aimed at providing a unified description of the processes taking place both in primary and secondary settling tanks for a more detailed operation and control in Water and Resource Recovery Facilities (WRRFs). First, experimental evidence is provided pointing out the flocculation

The analysis of a simplified activated sludge process (ASP) with one main dissolved substrate and one main particulate biomass has been conducted in steady-state conditions. The ASP is formed by a plug-flow reactor anda settler tank. The biomass growth rate is described by a Monod function. For this process, it is not possible to get an explicit expression for the efflue

Purpose: The present study was performed as part of an epidemiological study, the Inter99 Eye Study. The aim of the study was to describe refractive errors and visual acuity (VA) in a suburban Danish population.Methods: The Inter99 Eye Study comprised 970 subjects aged 30–60 years and included a random control group as well as groups at high risk for ischaemic heart disease and diabetes mellitus.
