Minimization of Multistage RBC Active Disc Area

Journal of Environmental Engineering, 1993
An analytical approach to the minimization of total active disc area (\IA\dT\N), required for organic carbon removal [i.e., biochemical oxygen demand (BOD)] by a multistage rotating biological contactor (RBC), is presented. RBC operation is simulated using semiempirical models based on a saturation-type (Monod) removal rate, and on a first-order ...

[Measurement of the disc area by indirect ophthalmoscopy].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2009
The aim of this study was to assess the accuracy of measuring the optic disc area by indirect ophthalmoscopy.In a prospective clinical trial, 57 eyes of 29 subjects (age 57.3+/-12.1 years) were examined. The refractive error was -0.67+/-2.69D (+3.75D to -8D).The vertical and horizontal disc diameters (DD) were measured using a Haag-Streit slit lamp and

The correlation of the physiological blind spot and the disc area

1987
Peripapillary crescents of choroidal atrophy occur commonly in patients with glaucoma [6], particularly in those with low tension glaucoma [4] and may indicate the part of the optic nervehead that seems to be susceptible to glaucomatous damage [1]. It has been suggested that the absence of a peripapillary choroidal atrophy may indicate a more resistant

Holomorphically embedded discs with rapidly growing area

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1999
It is shown that if V is a closed submanifold of the open unit ball of ℂ2 biholomorphically equivalent to a disc, then the area of V ∩ r can grow arbitrarily rapidly as r ↗ 1. It is also shown that if V is a closed submanifold of ℂ2 biholomorphically equivalent to a disc, then the area of V ∩ r can grow arbitrarily rapidly as r ↗ ∞.

Optic Disc Rim Area, Pallor, and Nerve Fiber Course

Archives of Ophthalmology, 1989
To the Editor. —An important objective of most examinations of the optic nerve head is to estimate the mass of nerve tissue, which is assumed to reflect the number of retinal ganglion cell axons leaving the eye. Current clinical estimates in the living eye are based on measurements of the cup/disc ratio or the rim area and suffer from a strong ...

Inner Area Aberration Compensating Lens for Compact Disc (Compact Disc-Recordable)-Digital Versatile Disc Compatible Head

Japanese Journal of Applied Physics, 2001
We have developed a dual-wavelength digital versatile disc(DVD)/compact disc(CD)-compatible inner area aberration compensating lens capable of reading compact disc-recordable (CD-R) disks. In order to be able to read CD and CD-R disks with an infrared laser, it is essential to increase the numerical aperture (NA) of the inner area, but the ...

Similarities of Total Disc Parameters for Glaucoma-like and Open-Angle Glaucoma Discs Matched by Optic Disc Area Size

1991
We matched 17 eyes of patients with open-angle glaucoma with 17 eyes of patients with glaucoma-like discs by disc area size. We found no significant difference between the two groups for the total disc with respect to cup volume, area, depth, neuro-retinal rim area, slope and area of pallor.

An asymptotic bound for the residual area of a packing of discs

Mathematical Proceedings of the Cambridge Philosophical Society, 1966
Suppose that a sequence of discsarranged in decreasing order of diameters, forms a packing within the unit plane square I2. It has been shown, by Florian(1), that the area ofis at least O(a), where a is the radius of θn. However, Gilbert (2) has produced some empirical results for the Apollonius packing 71 of discs which seem to suggest that for such a
